SBPMat´s community people: interview with Osvaldo Novais de Oliveira Junior.

On January 29, 2016, in the city of Campinas (São Paulo State, Brazil), Osvaldo Novais de Oliveira Junior took office in the new executive board of the Brazilian Materials Research Society (SBPMat), acting as president. Novais is a professor of the São Carlos Institute of Physics (IFSC) at the University of São Paulo (USP). He has been a researcher in the field of Materials for 35 years, during which time he has published over 460 articles in indexed journals, 7 patents and 16 book chapters, among other publications. In total, the scientific production of professor Osvaldo has received, so far, over 8,500 citations according to Web of Science (index h=46) and 12,100 (h = 53) according to Google Scholar.

Osvaldo Novais de Oliveira Jr. was born on August 13, 1960 in Barretos, a city of the northern part of the State of São Paulo that, at that time, had approximately 60,000 inhabitants. When he was a teenager, he received the nickname of Chu, which accompanies him to this day, being also part of his professional electronic address.

He began his university studies in the Educational Foundation of Barretos. In 1980, while he was attending courses to obtain a teaching degree in Physics, he transferred to IFSC/USP to pursue a Bachelor degree in Physics, and started to work in research projects in the Electrets Group, nowadays referred to as Polymers Group “Bernhard Gross”. Within such group he began his master’s degree in 1983, supervised by professor Guilherme Fontes Leal Ferreira, obtaining in 1984 the title of Master in Applied Physics. In the following year he began to teach courses in the Bachelor Degree in Physics at USP São Carlos and continued developing research activities in the Polymers Group.

In 1986, he moved from São Carlos to the Welsh city of Bangor, United Kingdom, for doctoral degree studies in the University of Wales – nowadays Bangor University. In 1990, he obtained the title of Doctor in Electronic Engineering by defending his doctoral dissertation concerning electrical properties of Langmuir films, supervised by professor David Martin Taylor.

Back to Brazil in 1991, he added to his teaching activities at USP São Carlos, some classes in the graduation courses in Applied Physics. In 1993, he was named associate professor in that university.

In the same year, he conducted his first academic research works in natural language processing, an area that basically deals with problems related to automatic generation and understanding of texts by means of computers. Professor Osvaldo Novais was part of the team that founded the Interinstitutional Center for Computational Linguistics (NILC) and participated in the development of the first software for grammar revision of Brazilian Portuguese, which was named “ReGra”. The grammar checker was part of several versions of Microsoft Word processor as from 1999. From the work in NILC and scientific writing courses, he produced a book, together with more 7 authors, on scientific writing in English (“Writing Scientific Papers in English Successfully: Your Complete Roadmap”).

Osvaldo Novais was a visiting researcher in the University of Massachusetts Lowell (UMass Lowell), in the United States, between 2000 and 2001, and a visiting professor of University of Aveiro (Portugal) in 2006. Also in such year, he received Scopus Award, granted by Elsevier do Brasil and Capes (the Brazilian agency in charge of post-graduate programs), as one of the 16 Brazilian researchers with greatest scientific production, based on the number of publications, citations and supervisions (nowadays, there are 40 completed master theses and doctoral dissertations).

In 2008, he became a full professor of USP.

Nowadays, in addition to his activities as professor and researcher in IFSC-USP, Prof. Osvaldo Novais is a member of the coordination in Physics at FAPESP (the São Paulo research foundation), regional editor for South America of “Display and Imaging” scientific journal and associate editor of “Journal of Nanoscience and Nanotechnology”.

Here you find an interview with the researcher.

SBPMat Newsletter: – Tell us what made you become a researcher and work in the field of Materials.

Osvaldo Novais: – My professional choices almost always occurred without planning or specific motivation. I began the course for obtaining a teaching degree in Sciences in the Educational Foundation of Barretos, since I did not pass the entrance examination for being admitted in the Electronic Engineering graduation course, which I thought was the career I would like to have. After having decided to change area at the end of the first year and to do the entrance examinations for Philosophy and Psychology courses, for financial and personal reasons, I ended up continuing in the Sciences course and chose a teaching degree in Physics in the third year. There was a major transformation when I transferred to the Bachelor degree in Physics in USP São Carlos, and started participating in research projects. There I decided to become a teacher and researcher. My choice for the area of polymers was the result of a suggestion from a friend, who had great admiration for the faculty members of the Electrets Group at that time. Thus, I began doing research activities in such group, nowadays called Polymers Group “Bernhard Gross”, where I have been for 35 years.

Although I have not chosen a career or a research area due to a vocation or conviction, I was very fortunate because I consider the study of materials both fascinating and essential for society. Researchers in materials may amuse themselves with challenges and contribute to make this world a better place. Research training also allowed me to act in different areas, which is an important factor for those passionate for knowledge, as it is my case.

SBPMat Newsletter: – What are, in your own assessment, your main contributions to the field of Materials?

Osvaldo Novais: – I believe my greatest contribution was to have participated in the construction of a network of research in materials, mainly in nanostructured organic films. Such network nowadays comprehends researchers in many regions of Brazil,  and also includes international connections. Concerning specific scientific contributions, I could possibly point out the study of electrical properties of Langmuir films, as well as the use of such films as cell membrane models. It could also be worth to point out sensors (such as electronic languages) and biosensors produced with nanostructured films, noting that the main actors of such contributions have been students and doctoral candidates of my research group.

SBPMat Newsletter: – In parallel to your performance in Materials research, you develop studies concerning natural language processing within NILC, center of which you are founding member. Tell us a little bit about this activity.

Osvaldo Novais: – Out of need, I ended up becoming interested in scientific writing in English, in a work that was, at first, informal and that resulted in projects of software tools for writing aid. Being invited to participate in the team that developed the first grammar checker for Portuguese in the 1990s, NILC was created, which to this date is a reference worldwide for Portuguese language automatic processing. I say that without any embarrassment whatsoever, since all merits for this achievement go to a team of computer scientists and linguists, of several universities of Brazil, who have been conducting research and development of the highest level for years. My participation was merely important in the beginning.

For two decades, my research in natural language processing with NILC was fully disconnected from Physics, but in the last years we have used statistical physics methodologies for text treatment. With the new research paradigm based on intensive use of data (called “Big Data”), now there is the possibility of combining nanotechnology – an area that is predominantly of materials – with natural language processing and artificial intelligence, for example, in the diagnosis systems supported by computer. This is a fascinating topic that allows exercising technological convergence, which will boost research and development in the 21st century.

SBPMat Newsletter: – Briefly tell us what are your plans for SBPMat while president of the society within 2016-2018.

Osvaldo Novais: – I believe that the most relevant plan is to continue the excellent work that the previous executive boards have carried out, which made SBPMat be one of the most powerful scientific societies in Brazil. That includes keeping the excellent level of our annual meetings and strengthening the international insertion that it has achieved. Other goals of the new executive board are: to increase the interaction of materials researchers with the industries installed in Brazil, to encourage the participation of young researchers in the society and to promote scientific and technological popularization programs, emphasizing the key role of research in materials for technological and social development.

SBPMat Newsletter: – We always invite the interviewees of this newsletter section to leave a message for the readers who are beginning their scientific careers. Would you like to say something in particular for the future/ junior scientists?

Osvaldo Novais: – My message is: apply yourself and strive towards obtaining strong scientific training, focusing on languages of knowledge, whatever the natural languages (in our case, Portuguese and English) and languages of mathematical formalisms. Such strong training will allow you to continuously learn, which is essential in an ever-changing society. May you follow your dreams by solving scientific and technological problems, which is one of the most amusing and refreshing activities.

Featured paper: New member of the family of photovoltaic materials.

[Paper: Photovoltaic effect in Bi2TeO5 photorefractive Crystal. Ivan de Oliveira, Danilo Augusto Capovilla, Jesiel F. Carvalho, Renata Montenegro, Zanine V. Fabris and Jaime Frejlich. Appl. Phys. Lett. 107, 151905 (2015). DOI: 10.1063/1.4933097.]

New member of the family of photovoltaic materials

The photovoltaic effect consists in the generation of direct electrical current in a material, in consequence of its exposure to light, in the absence of an applied electric field.

In an article recently published in Applied Physics Letters, a Brazilian team of scientists presented striking experimental evidences of the presence of photovoltaic effect in bismuth telluride (Bi2TeO5) crystals. Until the publication of the paper, the material was known, for example, for being photorefractive (its reafractive index is altered in consequence of its exposure to light), but there was no evidence of its photovoltaic nature.

“The greatest contribution of this article lays in the fact that we showed for the first time that the Bi2TeO5 crystals exhibit the photovoltaic effect”, highlights Ivan de Oliveira, Professor of Faculty of Technology (FT) at State University of Campinas (UNICAMP) and author of the said article.

The published work was performed at the Optics Laboratory at FT – Unicamp, in the city of Limeira (SP), in collaboration with the Physics of Materials Group of the Federal University of Goiás e with the Optics Laboratory of the Institute of Physics “Gleb Wataghin” at UNICAMP. The collaborators gathered their experience in manufacture and characterization, respectively, of photorefractive crystals.

The study that originated the article is part of the master’s degree research of Danilo Augusto Capovilla, under the guidance of Professor Oliveira, in which some results indicated that the Bi2TeO5 crystals might exhibit photovoltaic effects. “Upon such indications, we performed several experiments and managed, using direct and indirect measures, to show that the Bi2TeO5 crystals in fact present the photovoltaic effect”, says professor Oliveira. “The demonstration of the effect was performed using non-holographic techniques and, mainly, stabilized holographic record techniques”, he completes.

One of the experiments conducted consisted in measuring the photovoltaic current of the non-doped bismuth tellurite sample and, for comparison, of a material in which the photovoltaic effect is already known, the iron-doped lithium niobate.

Scheme of direct measure of photovoltaic effect in Bi2TeO5 crystals. The sample is lighted with laser light and a current is generated in the volume of the material. The current is generated in the absence of electric field.

In addition to leave some questions which answers might be searched in new researches, such as the origin of the photovoltaic effect in the studied crystal, the article creates possible applications to bismuth telluride in light conversion into electricity, information storage and manufacture of optical components.

Featured paper 
A team of scientists from Brazil developed “nanomanipulations” in samples prepared in Israel, composed of serpentine-shaped carbon nanotubes over crystalline quartz. Through experimental and theoretical analyzes, the scientists were able to measure the strain suffered as a result of nanomanipulations and to understand phenomena related to the adhesion of nanostructures over materials such as quartz. Researchers condensed the study’s findings in a mathematical equation applicable to various materials. The results of the study were recently published in Nano Letters. See our story about the paper.
People in the Materials community 
We interviewed the winner of the Capes Doctoral Dissertation Award in the Materials area, Edroaldo Lummertz da Rocha, PhD in Materials Science and Engineering from the Brazilian Federal University of Santa Catarina (UFSC). Edroaldo became interested in science because it would enable him to help people somehow.  In his doctoral research, he worked on the interface among Materials Science, Computer Science and Biology to study the interaction between biological cells and nanomaterials. He generated knowledge that can lead to the development of new drug delivery systems. In addition to this satisfaction, his PhD gave him the gratification of seeing two articles he co-authored on high-impact journal covers. See our interview with Eldroaldo and data about other dissertations related to Materials area which also were awarded by CAPES this year.

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.

Edgar Zanotto.

Edgar Zanotto.

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.

George Malliaras.
George Malliaras.

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.
