Report of the XIV SBPMat Meeting: plenary lectures with their files, memorial lecture, symposia, awards…

OPENING CEREMONY

Sunday, September 27. By 6:45 pm. Hundreds of people enter the plenary room of the Convention Center “SulAmérica”, in Rio de Janeiro (Brazil) for the opening ceremony of the 14th annual meeting of the Brazil Materials Research Society, whose acronym in Portuguese is SBPMat. The opening table is composed by the chairmen of the event, Prof. Marco Cremona (Brazil) and Prof. Fernando Lázaro Freire Junior (Brazil), as well as the present SBPMat president, Prof. Roberto Mendonça Faria (Brazil), the immediate past president of the European Materials Research Society (E-MRS), Prof. Rodrigo Martins (Portugal), and the general secretary of the International Union of Materials Research Societies (IUMRS), Prof. Robert Chang (USA). Behind them, a big banner shows the logos of dozens of institutions and companies that gave financial support to the event.

At the opening table, from the readers´ left: Prof. Rodrigo Martins (Portugal, E-MRS immediate past president and IUMRS officer), Prof. Fernando Lázaro Freire Junior (Brazil, chair of the event), Prof. Marco Cremona (Brazil, chair of the event), Prof. Roberto Mendonça Faria (Brazil, SBPMat president), and Prof. Robert Chang (USA, IUMRS general secretary).

Near 1,000 attendants are present at the ceremony, which starts with the Brazilian national anthem. The chair Prof. Cremona welcomes the participants to the meeting. Prof. Robert Chang, who was president of MRS (Materials Research Society) in 1989 and founded IUMRS in 1991, convokes the participants of all countries to try to solve together the most important global challenges for materials research, related to health, food, environment, transport etc. Representing E-MRS, Prof. Martins, who presently takes care of Global Leadership and Service Award at IUMRS, emphasizes his desire of promoting international connections. Prof. Faria talks a little bit about Brazil, which, as well as other developing countries, is very rich in raw materials but needs to add value to its products by means of science and technology.

After the opening, Prof. Eloisa Biasotto Mano (Brazil) goes to the stage for the Memorial Lecture “Joaquim da Costa Ribeiro“, which is a distinction bestowed annually by SBPMat on a Brazilian researcher with outstanding career in the field of Materials. This 91-year-old scientist pursued international scientific education at a time when most women were illiterate in Brazil, and founded in the Federal University of Rio de Janeiro (UFRJ) the first research group in polymers in the country. This group later became the Institute of Macromolecules (IMA), which was directed by Eloisa until she retired. In the memorial lecture, she talks about macromolecular materials and, using a representation of a polyethylene molecule made by herself with wire, she shows how these kind of molecules behave in response to their big size. A group of Prof. Eloisa´s disciples (among them, the present director of IMA) assists her with the presentation, showing affection, gratitude and admiration for her . After the talk, many attendants of diverse ages make a queue to take a picture with this protagonist of the dawn of polymer science in Brazil. Eloisa, who is professor emeritus of UFRJ, poses for all the pictures she is ask to. At the end of the photo session, she accepts our microphone and leaves a message for the young people starting a carreer in science:

Right after the memorial lecture, in the same venue, the participants enjoy the welcome cocktail while meeting friends and collaborators. The cocktail is animated by live “chorinho” music, an instrumental Brazilian popular genre original from Rio de Janeiro.

PLENARY LECTURES

Nader Engheta

Nader Engheta.

Monday, September 28. At 8:30 in the morning, the plenary room is full of attendants waiting to learn about metamaterials and the extreme behavior of waves interacting with them in the first plenary lecture of the event. The speaker is Nader Engheta, the H. Nedwill Ramsey Professor of Electrical and Systems Engineering at the University of Pennsylvania (United States). This Iranian-born scientist is a recognized world leader in research on metamaterials, and holds an H number of 69. Through experimental and theoretical research, Engheta and his collaborators have created such unconventional things as nanocircuits made of metamaterials that function as optical filters. Since the beginning of the talk, Engheta captivates the audience with some history of science and with a world of structures created by using particular composite metamaterials with particular sizes and geometries and arranged in particular ways with the aim of obtaining unconventional interaction with light and other waves.

In the afternoon, at 3:30, more than 400 people attend the second plenary lecture, which is about glass-ceramics (materials formed through controlled crystallization of certain glasses). The speaker is the Brazilian researcher Edgar Zanotto, Professor at the Federal University of São Carlos (UFSCar), in Brazil, where he founded and heads the Vitreous Materials Laboratory (LaMaV) that assembles a big international team. Zanotto, who is a world-renowned expert on glass-ceramics, presents in his lecture many useful applications of these materials, such as cooking hobs or artificial bones and teeth. He also mentions the scientists who, along 60 years of glass-ceramics history, contributed to the advancement of research on that topic. In spite of those contributions, the comprehension of some aspects of the formation of glass-ceramics is not complete, he says, but that is not a problem for glass-ceramics fabrication and applications. It´s just an opportunity for fundamental scientists.

Paul Ducheyne. Biomaterials. Merging Materials Science with Biology.

Paul Ducheyne.

Tuesday, September 29. 8:30 am, time for the third plenary lecture of the event. The lecturer, Prof. Paul Ducheyne, also comes from University of Pennsylvania (USA), where he directs a multidisciplinary center for bioactive materials and tissue engineering research. An authority on biomaterials field, Ducheyne is the editor in chief of a six-volume book on biomaterials published in 2011. In the talk, he shows a series of biomaterial-made devices, grafts, scaffolds etc., most of them already being commercialized, that actively interact with the body, either by promoting tissue formation (for example, bone) or by releasing drugs for diverse treatments. Ducheyne presents their effects on solving health problems, numbers about their markets, and scientific recent advances that can make them even more effective.

Ulrike Diebold. Surfaces of Metal Oxides.
Ulrike Diebold.

Some hours later, at 3:30 pm, hundreds of participants cluster again, this time around Prof. Ulrike Diebold, whose research group at UT Wien (Austria) is devoted to the understanding of fundamental mechanisms and processes occurring in surfaces at the atomic scale. Prof. Diebold catches the audience attention from the beginning to the end by showing, through scanning tunneling microscopy images, how she spies the behavior of atoms on the surface of metal oxides – topic in which she is a worldwide leader researcher. In particular, she reveals two secrets of metal oxide surfaces: the first one about how oxygen adsorbs on titanium dioxide and the second one about how active single metal atoms are in oxidation process in magnetite.

Wednesday, September 30. In the plenary lecture of the morning, the audience is transported again to the social-impacting world of biomaterials by Prof. George Malliaras, Greek-born, working at École Nationale Supérieure des Mines de Saint-Étienne (France), where he heads the Department of Bioelectronics. Malliaras has an H index of 64. After many years working on organic electronics, he entered the new field of organic bioelectronics and obtained impacting results. His research is about electronic devices made of conducting polymers that match properties of living tissues. These devices are used for interfacing with human brain – a “natural electronic device”. The final purpose is to study brain activity or diagnose and even treat neurological diseases such as epilepsy. An example of device is a transistor that enables boosted in vivo recording of brain activity with low invasion. As suggestions for the materials community, Malliaras highlights the importance of collaboration with neuroscientists and physicians and the challenge of improving the understanding of electronic transport and structure.

Ichiro Takeuchi. Combinatorial Approach to Materials Discovery.

Ichiro Takeuchi.

In the talk of the afternoon, the speed of science progress accelerates following the beat of the combinatorial approach. Prof. Ichiro Takeuchi, from University of Maryland (USA), explains how his group manages to optimize materials and properties discovery. As well as in lottery one can buy a big number of tickets to have more chances to win a prize, in materials discovery scientists can produce a huge number of combinations of elements to obtain a compound with desirable properties. For example, for quaternary compounds, millions of combinations are possible, from which only 0,01 % are known. In Prof. Takeuchi´s lab, machines for thin film deposition used with masks work night and day to create patchwork-like samples containing libraries of similar compounds. Then, the libraries are characterized by rapid tools, giving information about the properties of several compounds at the same time. Coupled with appropriate theory and computational simulations, these high-throughput experiments become real materials discovery engines.

Claudia Draxl. On the Search of Novel Materials: Insight and Discovery though sharing of big data.
Claudia Draxl.

Thursday, October 1st, 8:30 am. In the last plenary lecture of the event, Prof. Claudia Draxl (Humboldt University, Germany) publicly wonders how to make available the huge amount of data resulting from experiments around the world, high-throughput screening, computer clusters etc. Why to do that with scientific data? For confirmation, broad dissemination in society, sharing with distant collaborators and reuse with new purposes. With that aim, Prof. Draxl and collaborators from European countries are facing the development of a repository of materials raw data, called Novel Materials Discovery (NoMaD), which hosts, organizes and shares materials data on the web.

SYMPOSIA SESSIONS

Some of the symposia coordinators with the meeting chairs and the SBPMat president.

The symposia at SBPMat annual meetings are selected from proposals that can be submitted to the event committee by any scientist from anywhere in the world. This edition of the event encompassed 26 symposia (including the satellite event “8th International Summit on Organic and Hybrid Solar Cells Stability”) and 2 workshops, and it registered symposia coordinators from Argentina, Denmark, England, France, Germany, Italy, Ireland, Japan, Portugal, Spain, Swiss, USA, and, of course, Brazil. Within the symposia, near 190 invited speeches and more than 2,000 technical works are presented and discussed in oral and posters sessions, on a wide range of subjects going from carbon nanostructures to biomaterials, from characterization techniques to computer simulation, from materials for sustainable development to safe use of nanomaterials.

While some symposia have been held year after year in the SBPMat meeting, the University Chapters symposium was a novelty of this year meeting. It was completely organized by students from diverse points of Brazil who are coordinators of the SBPMat University Chapters. The chapters are organized teams, affiliated with the society, composed of graduate and undergraduate students working in materials field. The members of these groups carry out diverse activities that complement their academic education. The students from the existing chapters, which were eight in number up to the moment of the meeting, faced the challenge of organizing a symposium – a task that is usually done by senior researchers.

In fact, students have not only active but also massive participation in the XIV SBPMat meeting. Almost half of the attendants (950 people) were master, doctoral and even undergraduate students doing research on materials field. In Brazil, the federal agency for research support, CNPq, has a program called “scientific initiation” that grants scholarships to undergraduate students to conduct research under the supervision of a Professor.

For the oral sessions of the symposia, all along the meeting, after the morning plenary session, and before and after the afternoon plenary talks, the attendants distributed themselves among 17 rooms. The poster sessions took place at the end of the afternoon from Monday to Wednesday and in the morning on Thursday. Walking through the long corridors of the poster sessions, one could see active scientific discussion, many times between a young author and a renowned researcher. One could also hear very positive comments about the original arrangement of the poster panels. The size of the poster session was impressive. In total, near 1,800 research works were presented in the posters.

Plenary talks of the meeting: know more about the speechs and the speakers

When interacting with advanced materials, light and other waves can behave in quite an unusual way. In the XIV SBPMat Meeting, Nader Engheta, a world expert in materials created by humans known as metamaterials, will speak of extraordinary phenomena that occur when materials developed in his research group interact with light. Among other significant contributions, Engheta and his colleagues have created nanoscale optical circuits using metamaterial arrangements. In an interview to our newsletter, this Professor of the University of Pennsylvania (United States) spoke of this and other contributions, which were published in some of the most renowned scientific journals. In a message to our readers, he mentioned the thrills of a scientist’s life. See the interview.

We also interviewed Professor Edgar Zanotto (UFSCar, Brazil), whose plenary talk will be about glass-ceramics – materials formed from the crystallization of certain glasses. Since the beginning of his scientific career, Zanotto has been studying the mechanisms for glass-ceramics formation and developing applications for them. In the XIV SBPMat Meeting, the scientist will talk about past and future, including the development of new glass-ceramics and their use in new products. See the interview.
We also interviewed Professor Paul Ducheyne, from the University of Pennsylvania (USA). For about 4 decades, Ducheyne has dedicated himself to the study of biomaterials, field in which he is the author of hundreds of papers summing over 10,000 citations, besides 40 patents and books. In the interview, Ducheyne listed some of his most important contributions to the field, such as explaining how synthetic materials lead to tissue formation. In his plenary talk during the XIV SBPMat Meeting, Ducheyne will obviously address biomaterials; particularly bioactive ceramics with in situ functionalization and sol-gel materials used for the release of drugs and growth factors. See the interview.
Professor Ulrike Diebold (UT Wien, Austria) will speak in the XIV SBPMat Meeting about the surfaces of metal oxides. These materials are used for gas monitoring, catalysis, anti-corrosion, energy conversion, pigmentation and many other applications. Using her scanning tunneling microscopes (STM), Diebold investigates, for example, atomic-scale defects in the network of metal oxides. In our interview, she talked about his major contributions in the field of metal oxides and about the power of STM technique for the study of surfaces. She also left a tempting invitation to go to her lecture. See the interview.
Organic electronics applied to the study of the brain and the diagnosis and treatment of neurological deseases will be addressed by Professor George Malliaras, director of the department of Bioelectronics of the École Nationale Supérieure des Mines de Saint-Étienne (France). Examples of these applications are devices based on organic materials used to record and stimulate the cerebral activity. In an interview to our newsletter, Malliaras spoke about the importance of interdisciplinary collaboration to generate research with social impact in his research field. The scientist also mentioned some of his main contributions in organic electronics and bioelectronics. See the interview.
Professor Ichiro Takeuchi, from the University of Maryland (USA), will talk in the SBPMat Meeting about the combinatorial approach in the field of Materials. This methodology, which substantially accelerates the rate of several research processes, has been helping Professor Takeuchi to discover a number of compounds and develop strategies to quickly determine the relation between composition, structure and property in many materials. In our interview, the scientist explains how the combinatorial research works in practice, and lists some of his main contributions to the field. He also discusses a topic of his plenary lecture: the “integrated materials engine”, which combines theory and high-throughput experiments in order to discover new materials. See the interview.
In times of “big data”, Professor Claudia Draxl, from Humboldt University (Germany), will discourse about how to exploit the wealth of information, inherently inside the materials data, which promises unprecedented insight.

Featured paper

A team of scientists from Brazilian institutions (UCS, Unicamp and UFRGS), with a chemical approach on an issue traditionally addressed with physics, managed to advance in the understanding of adhesion and delamination of DLC thin films deposited on steel surfaces. The results of the study, which were published in ACS journal devoted to applied interfaces and materials, can help optimize the deposition of these films, thus expanding its use in the industry in applications of high impact, such as increasing the energy efficiency of car engines. See our story about the paper.

SBPMat´s community people

We interviewed Sergio Neves Monteiro, currently Professor at the Brazilian Militar Institute of Engineering (IME). Neves Monteiro worked in the introduction of Materials research in Rio de Janeiro State. He was associate dean of graduate studies and research at the Federal University of Rio de Janeiro (UFRJ), higher education secretary in the Ministry of Education, assistant secretary of science and technology in the State of Rio de Janeiro and president of the Rio de Janeiro research foundation (FAPERJ), among other functions. In an interview to our newsletter, he spoke a bit about his career and left a message for our readers who are beginning their careers as researchers: “I remember you that, much more than a career with stability and adequate remuneration in teaching and research institutions, being a researcher can bring great personal satisfaction and the certainty of contributing directly to the country’s development. See the interview.

Featured paper: United atoms, adhered films.

[Paper: Identification of the Chemical Bonding Prompting Adhesion of a-C:H Thin Films on Ferrous Alloy Intermediated by a SiCx:H Buffer Layer. F. Cemin, L. T. Bim, L. M. Leidens, M. Morales, I. J. R. Baumvol, F. Alvarez, and C. A. Figueroa. ACS Appl. Mater. Interfaces, 2015, 7 (29), pp 15909–15917. DOI: 10.1021/acsami.5b03554]

United atoms, adhered films

With an innovative approach on an academic and industrial problem, a study wholly conducted in Brazil has brought significant advances in the understanding of the adhesion of DLC (diamond-like carbon) films on steels. The results of the work, which were recently published in the journal Applied Materials and Interfaces of the American Chemical Society (ACS), can help optimize such adhesion, thus prolonging the life of DLC films and expanding their use in the industry.

The team of scientists was particularly interested in the DLC potential to increase the energy efficiency of internal combustion engines. In fact, if all car engine components were coated with DLC films, the owner of that car would spend 5-10% less fuel and save the environment a good deal of greenhouse gas emissions and other pollutants, among other advantages. The reason for such saving lies in the ultra-low friction of DLC, since friction is the force responsible for wasting fuel while providing resistance to the motion that the parts of the engine make among themselves.

However, DLC has a drawback: it does not adhere to steel, causing quick delamination of the films from the substrate. To work around this problem, both in the laboratory and in industry, it is customary to deposit a layer containing silicon, known as interlayer, over the steel. The DLC film is then deposited on top of it. The result is a “sandwich”, which does not come undone easily.

In the paper published in the ACS journal, the authors experimentally analyzed a “sandwich” consisting of a steel substrate, an interlayer of silicon carbide (SiC) and a DLC film. Both the interlayer and the film were deposited by a quick process that generated thin layers of a few nanometers (up to 10). Mainly, two issues differentiated this study from other similar studies in the scientific literature. Firstly, the team focused in analyzing what happened in two regions corresponding to the interfaces of the interlayer with the film (upper) and with the steel (lower). Secondly, the scientists made a chemical approach on the matter of adhesion.

“This work has identified the chemical structure that generates adhesion in lower (SiCx: H/steel) and upper (a-C:H/SiCx:H) interfaces, which make up the a-C:H/SiCx:H/steel sandwich structure”, said Carlos A. Figueroa, professor at the University of Caxias do Sul (UCS) and corresponding author of the article. “The mechanisms found in the bibliography raised physical or mechanical aspects, but not chemical ones,” said Figueroa, who graduated in chemical sciences from the University of Buenos Aires (UBA) and has a doctorate degree in physics from the State University of Campinas (Unicamp). “However, adhesion is generated by the sum of all individual chemical bonds existing among DLC, the interlayer and steel,” he adds.

Scientists kept a constant film deposition temperature, but varied the interlayer deposition temperature, generating a group of samples deposited at 100° C and another one at over 300° C. After analyzing them by a variety of techniques, especially, X-ray photoelectron spectroscopy (XPS), researchers found that the lower interface of the interlayer, regardless of the deposition temperature, was largely composed of silicon atoms (from the interlayer) bonded to iron atoms (from the substrate). At the upper interface of the interlayer, the team found differences according to the deposition temperature of the interlayer. In the samples deposited at 100° C, oxygen atoms bonded many of the silicon and carbon atoms, preventing the carbon of the film to strongly bond to the silicon of the interlayer, and resulting in a film without good adhesion. In turn, scientists did not find oxygen in the interface of the samples deposited at over 300° C, but bonds between carbon and silicon atoms, which caused the film adhere well to the interlayer.

In the center, a real engine cylinder displays, on the left side, a DLC film (in black) delaminated on the interlayer deposited at 100° C and, in the right side, the same film well adhered on the interlayer deposited over 300° C.

Besides Figueroa and students of the research group he leads in UCS, also authored the paper researchers from the Institute of Physics at Unicamp, where the XPS measures were made, as well as a scientist from the Federal University of Rio Grande do Sul (UFRGS) that, together with the other authors, participated in the discussion of results.

The work received the support from Brazilian Science funding bodies (Capes, CNPq through INCT National Institute of Surface Engineering, Fapergs), of Petrobras, UCS, the European Commission (Marie Skłodowska – Curie Actions) and Plasmar Tecnologia (a small company that is developing, through a TECNOVA RS project, an industrial equipment to deposit DLC on steel aiming to increase the energy efficiency of car engines).

SBPMat´s community people: interview with Sergio Neves Monteiro.

Sergio Neves Monteiro graduated in Metallurgical Engineering from the Federal University of Rio de Janeiro (UFRJ) in 1966. Soon after graduation, he went to the United States to continue his education at the University of Florida (UF), invited by a professor from that university. At UF he developed work on deformation of materials and obtained master’s (1968) and doctorate (1972) degrees, both in Materials Science and Engineering. In 1976 he held a postdoctoral fellowship in Germany, at the University of Stuttgart.

Between his masters and doctorate, he returned in 1968 to UFRJ as a professor and became coordinator of the Metallurgical Engineering course, as well as he participated in the creation of the Metallurgical and Materials Engineering Program in the Institute Alberto Luiz Coimbra for Graduate Studies and Research in Engineering (COPPE). He was full professor of the Metallurgical Engineering department at UFRJ and COPPE until he retired from his post in the university in 1993. Then he started working in the Darcy Ribeiro State University of the North of Rio de Janeiro (UENF), where he took part in the implementation of the university and created the Advanced Materials Laboratory. He was full professor at UENF until 2012.  Since 2012, he is a collaborating professor of the Military Institute of Engineering (IME), also in Brazil.

Throughout his career, he held various management positions at UFRJ, UENF, the research foundation of the State of Rio de Janeiro (FAPERJ), the Brazilian Ministry of Education (MEC), the Department of Science and Technology of the State of Rio de Janeiro and the Brazilian Association of Metallurgy and Materials (ABM), among other institutions.

He is holder of a fellowship 1A from the Brazilian national research foundation (CNPq) for scientific productivity. In 47 years of academic life, he advised about 80 masters and doctoral dissertations and has published over 500 articles in national and international journals, as well as 58 book chapters.

He received awards and distinctions from ABM, FAPERJ and Institute of Superhard Materials (Ukraine), among others. He is a fellow of the American Society for Metals.

Here follows an interview with the researcher.

SBPMat Newsletter: – So what led you to become a researcher and work in the Materials area?

Sergio Neves Monteiro: – Since I was a child I have been interested in nature, like animals, rocks, stars, earthquakes, volcanoes and all that surrounds us. So when I was admitted into the School of Engineering at UFRJ, the area I was immediately interested in was Metallurgy and Materials. In my third year at the university, as monitor of professor Hervasio de Carvalho (then president of the National Nuclear Energy Commission, CNEN) I came into contact with research and was motivated to take courses at COPPE, which had recently been implemented at the UFRJ Chemistry School in Praia Vermelha. Invited by Professor Robert Reed-Hill, one of the professors of the course, I traveled to the University of Florida shortly after the completion of my undergraduate course to pursue masters studies, and thus, beginning my career as a researcher.

SBPMat Newsletter: – What, in your consideration, are your main contributions to the Materials area?

Sergio Neves Monteiro: – As a professor at UFRJ, I implemented in 1968, along with professors Walter Mannheimer and Ubirajara Cabral, the Metallurgical and Materials Engineering Program in COPPE. I was part of the education of the first masters and doctors in the area and participated in the organization of the 1st CIBECIMat, coordinated by professor Waldimir Longo from IME. I was Assistant Dean for Graduate Studies and Research at UFRJ, Secretary of Higher Education in MEC in Brasilia, Assistant Secretary of Science and Technology of the State of Rio de Janeiro and President of the Board of FAPERJ. In research, I have been actively and innovatively contributing with the following topics:

· Dynamic aging of metals;

· Properties of composites reinforced with natural fibers;

· Ballistic protection mechanisms associated with new materials;

· Characterization of conventional ceramic with incorporation of industrial waste;

· Processing techniques of diamonds and other metals/superhard alloys.

Details of my accomplishments are available in my curriculum in the Lattes Platform.

SBPMat Newsletter: – Leave a message for our readers who are starting their careers as scientists.

Sergio Monteiro Neves: – I congratulate the young Brazilian scientists for the path they have chosen. I remember that much more than a career with stability and adequate remuneration in teaching and research institutions, being a researcher can bring great personal satisfaction and the certainty of contributing directly to the country’s development. The publication of articles in international journals of high impact is a tremendous achievement with recognition by the community. Research has been one of the main tools for technological advances and quality of life in developed countries.

Memorial Lecture “Joaquim da Costa Ribeiro” for Prof. Eloisa Biasotto Mano.

Since 2011, every year, SBPMat (the Brazilian Materials Research Society) has been granting awards to researchers with outstanding work in the field of Materials.  Such researchers have the opportunity to make a lecture during the SBPMat annual meeting. The name of the award is Memorial Lecture “Joaquim da Costa Ribeiro”, in honor of Prof. Costa Ribeiro, a pioneer in Materials experimental research in Brazil. In 2015, the SBPMat award will be delivered to Eloisa Biasotto Mano, professor emeritus of the Federal University of Rio de Janeiro (UFRJ), during the opening of the XIV SBPMat Meeting, on September 27 at 19 pm in the SulAmérica Convention Center (Rio de Janeiro). During such event, in addition to receiving the award, Professor Biasotto Mano will speak of the importance of macromolecular materials.

Eloisa Biasotto Mano was born on October 24, 1924 in Rio de Janeiro. By 13 years of age, she did not know what science was, neither did she know what a scientist’s work was about, as these subjects were little present and were inaccessible to the public in Brazil at that time, when there was not even television in the country. However, there were books, and Eloisa had access to many of them in the printing house where her uncle worked as an editor. The girl, who was very serious and responsible, had been assigned to review the proofs of works translated from French. And behold, Eloisa had to read “Madame Curie”, the biography of that scientist woman, born in Poland, who had won two Nobel Prizes, and who had died a few years ago. “I found it great for someone to be so interested in something and have the life she’d had,” recalls Eloisa in an interview in the documentary “Eloisa Mano”. This is how Eloisa discovered the word “chemistry” and began to take an interest in this field of knowledge.

At 20 years of age, Eloisa Mano was admitted into the National School of Chemistry of the University of Brazil (UB), currently UFRJ, to carry out her studies. This occurred in the 1940’s, when less than 40% of women (and less than 50% of men) were literate in the country. Higher education was just beginning; institutions could be counted with the hands´fingers. But Eloisa graduated in Industrial Chemistry in 1947. In 1955 she also obtained the degree of the newly established course of Chemical Engineering. In 1949, she specialized in rubber technology at the National Institute of Technology, also in Rio de Janeiro, one of the few institutions, which, at the time, had infrastructure for experimental research. Given her good performance, she was invited to remain in the institution as a technology chemist, which allowed her to acquire experience in polymer technology.

At that point, Eloisa had higher education degrees, but she felt she could learn more. She thought that there should be a good option abroad and that she could somehow arrange her means to travel, since she could not afford the expenses herself. She then went to the US Embassy and was given great news: there was a scholarship for someone with her profile. Thus, between 1956 and 1957, she was able to study polymer science at the University of Illinois, USA, under the advisory of Professor Carl Shipp Marvel – considered a great scientist and a pioneer in the field of organic chemistry/polymers.

After her experience abroad, Eloisa returned to the National School of Chemistry at UB and worked in Industrial Microbiology for 5 years. In that period, she learned a lot with her mentor, Professor Raymundo Augusto de Castro Moniz de Aragão. Aragão was one of the instigators of the creation of a UB Chemistry Institute, dedicated to research and graduate studies, which happened in 1959. Later, Professor Aragão became the dean of the university and minister of Education and Culture of Brazil.

In 1960, Eloisa Mano obtained her PhD degree from UB with a dissertation in organic chemistry. In 1962, she was admitted into the Chemistry Institute of the UB after a highly competitive selection process, and obtained the chair of organic chemistry. That same year, the Chemistry Institute became one of the first institutions in the country to offer graduate courses and began accepting applications for Masters studies in organic chemistry and biochemistry.

In 1964, Eloisa left Brazil for her second training in polymer science, this time at the University of Birmingham (England), with Professor J.C. Bevington. The following year, Eloisa came back to Brazil and to the university, whose name had changed in 1965 to UFRJ, as it is currently. In 1968, Prof. Eloisa created the first research group in polymers in Brazil, initially composed of 9 master students advised by her, who worked on the UFRJ campus at Praia Vermelha. The Polymer Group gained a good reputation constantly attracting new members, but the physical infrastructure did not grow along with the group.

In 1972, the group managed to obtain financing from government agencies for the construction of a new building at the UFRJ campus at Fundão Island. The group then was named “Macromolecular Center”. Eloisa personally took care of the building’s project, and continued taking great care of her workplace after the building was constructed, in 1978.

In 1976, the center was transformed into the Institute of Macromolecules (IMA), and professor Eloisa became its first director, a position she held until her mandatory retirement in 1994. That year, IMA was renamed to Professor Eloisa Mano Institute of Macromolecules. In 1995 Eloisa was named UFRJ professor emeritus.

Along with her work at IMA, professor Eloisa engaged in international activities that contributed to internationalizing the IMA, generating opportunities abroad for students of the institute. Besides being part of the editorial board of several national and international journals in the field of polymers, Eloisa was a visiting researcher/ professor at universities and research institutes from the Netherlands, Norway and Spain (1972), Germany (1976), Mexico and the United States (1977), Argentina (1978), Japan (1979), Chile (1983), France (1989), among others.

In over half a century dedicated to research, Eloisa Mano advised about 50 masters and doctorate theses, and published 17 books, 4 book chapters and over 200 papers in national and international scientific journals. In these publications, she collaborated with about 250 co-authors.

Her performance was recognized through awards and distinctions by many different entities such as the American Chemical Society (ACS), Society of Plastics Engineers (SPE), Society of Polymer Science, Brazilian Chemical Society (SBQ), Brazilian Association of Chemistry (ABQ), Brazilian Association of Polymers (ABPol), Regional Chemistry Council, Rio de Janeiro Government, Presidency of Brazil and industry federations of Rio de Janeiro.

Materials created by applying the state-of-the-art in materials science and engineering and nanotechnology can make light and other electromagnetic waves behave in an extraordinary way, becoming very useful for applications in several fields.

To talk about this issue in the XIV SBPMat Meeting, Professor Nader Engheta (University of Pennsylvania, USA) will be in Rio de Janeiro in the end of September. Engheta is a recognized world leader in research on metamaterials – man-made materials created through micro or nanoengineering, and capable of interacting with electromagnetic waves in ways not found in nature.  Metamaterials can sculpt the waves in order to achieve unconventional light-matter interaction.

In Rio de Janeiro, Engheta will talk about extreme scenarios generated from metamaterials: light traveling at full speed through artificial structures, one-atom-thick optical devices, metamaterials that perform mathematical operations, miniaturized circuits – optical rather than electronic – composed by metamaterials, and structures with effective refractive index near zero.

In his childhood in Tehran (capital of Iran), Nader Engheta developed a special curiosity to understand phenomena related to waves. This curiosity propelled him to attend and get a BS degree in Electrical Engineering at the University of Tehran. In 1978, he came to the United States to pursue his post-graduate (master’s and PhD degrees), also in Electric Engineering, carried in the prestigious Caltech (California Institute of Technology), in the United States. In 1982, he got his PhD diploma from Caltech, with a dissertation in the field of electromagnetism. After a post-doctorate at the same institution, Engheta worked as a scientist in the industry for four years, working again with electromagnetism.  Then he joined the faculty of the University of Pennsylvania in Philadelphia in 1987, and was swiftly promoted through the professorial ranks, and now he is the H. Nedwill Ramsey Professor of Electrical and Systems Engineering, with affiliations in the departments of Electrical and Systems Engineering, Physics and Astronomy, Bioengineering and Materials Science and Engineering.

Owner of an H number of 69 according to Google Scholar, Engheta has more than 21400 citations. Besides being author of 28 book chapters and numerous journal articles and conference presentations, Engheta is coeditor of the book “Metamaterials: Engineering and Physics Explorations”, released in 2006 by Wiley-IEEE publisher. In 2012, he chaired the Gordon Research Conference on Plasmonics.

His contributions to science and engineering have received important recognitions and distinctions from several entities, as the international society of optics and photonics, SPIE (“2015 SPIE Gold Medal”), the international union of radio science, URSI (“2014 Balthasar van der Pol Gold Medal”) and the international professional association of electric and electronic engineers, IEEE (“2015 IEEE Antennas and Propagation Society Distinguished Achievement Award”, “2013 Benjamin Franklin Key Award”, “2012 IEEE Electromagnetics Award”, “IEEE Third Millennium Medal”), among many other entities. He is also Fellow of six international scientific and technical organizations, namely, Materials Research Society (MRS), American Physical Society (APS), Optical Society of America (OSA), American Association for the Advancement of Science (AAAS), SPIE, and IEEE.  Engheta also received several teaching awards.  In 2006 the Scientific American Magazine selected him as one of the 50 Leaders in Science and Technology for his development of metamaterial-inspired optical nanocircuitry.

Here follows an interview with Professor Nader Engheta.

SBPMat newsletter: – In your opinion, what are your most significant contributions on issues related to the topic of your plenary lecture? Explain them very briefly and if possible, share references of resulting papers or books, or comment if these studies have produced patents, products, spin-off companies etc.

Nader Engheta: – I am very interested in light-matter interaction, and in my group we explore different methods in manipulating and tailoring interaction of waves with material structures, both in the optical as well as microwave domains.  I am very excited about all the research topics my group and I have been working on.  Some of these topics include (1) The optical metatronic nanocircuitry, in which we brought the notion of “lumped” circuit elements from electronics into the field of nanophotonics, developing a new paradigm in which material nanostructures may function as optical circuit elements.  In other words, “materials become circuits” working with optical signals.  In this way, nanophotonics can be modularized, in an analogous way as in electronics.  This allows one to perform optical signal processing at the nanoscale, (2) Metamaterials that can do math:  following our work on optical metatronics, we are exploring how properly designed materials (e.g., layered materials) can interact with light in such a way that one can do mathematical operations with light.  In other words, we are exploring the following questions:  Can materials be specially designed to perform analog processing with light at the nanoscale?  As light propagates through such properly designed material structures, would the profiles of the output signals resemble the results of certain mathematical operations (such as differentiation or integration) on the profiles on the input signals?  In other words, can we design materials for specific mathematical operations in order to do “photonic calculus” at the nanoscale?  (3) The extreme scenarios in light-matter interaction: this may include extreme dimensionality, like graphene photonics as the one-atom-thick platform for light manipulation, extreme metamaterials in which material parameters such as relative permittivity and relative permeability attain near-zero values.  This category of materials, which we have named epsilon-near-zero (ENZ), mu-near-zero (MNZ) and epsilon-and-mu-near-zero (EMNZ) materials, exhibit very interesting features in their response to electromagnetic wave interaction.

SBPMat newsletter: – Help us visualize the metamaterials developed by your group. Please choose one of your favorite photonic materials and tell us, very briefly, its composition, its main properties and its possible applications.

Nader Engheta: – One of the structures developed by my group is the optical metatronic nanocircuits for mid-IR regime (from 8 to 14 microns), in which we properly tailored and constructed nanorods of Si3N4 with specific widths and thicknesses, separated by a specific gap.  These arrays of Si3N4 nanorods function as collections of optical nanoinductors, optical nanocapacitors and optical nanoresistors in mid IR.  We demonstrated that such structures behave as nanoscale optical circuits, with functionality analogous to electronic filters, but here these material structures operate in the mid IR regimes.  We have shown how these structure operate as optical filters in the mid IR, offering exciting applications for future integrated optical devices and components.

Later, in collaboration with my colleague Professor Cherie Kagan and her group at UPenn, we extended this work into the near IR regime (from 1 to 3 microns).  In this case, we used the indium tin oxide (ITO) as the material of choice, with proper design and patterning of ITO nanorods. We also demonstrated that such ITO-based optical metatronic circuits function as an interesting platform for optical circuitry and filtering.  This can have exciting possibilities in the silicon photonics.

SBPMat newsletter: – If you want, leave a message or invitation to your plenary lecture to the readers that will attend the XIV SBPMat Meeting.

Nader Engheta: – One of the exciting features of doing science is the joy of search for unknowns and the thrill of discovery.  I always believe that we should follow our curiosity and our passion for discovery. Also, in science and technology it is important to maintain the balance between the complexity and the simplicity in search for solutions to scientific inquiry.
