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


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.



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.

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.

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.

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.

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.

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.

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.



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.

Twice a day from Monday to Wednesday, the attendants could take a break and have a coffee with cookies while visiting the exhibition of the event, which encompassed 32 stands showing a variety of scientific instruments, services, scientific journals, books and opportunities for the materials community. In addition, on Wednesday, the participants had the opportunity to attend four hours of technical talks given by some expositors about fabrication and characterization techniques.

On Thursday by 12:30 the closing ceremony started. In the closing panel, Prof. Soo Wohn Lee, from MRS Korea and conference chair of the IUMRS-ICAM 2015, joined the representatives of SBPMat, E-MRS and IUMRS.

The meeting chair Prof. Cremona presented some photos of the past days and hours that made the public remember so nice and fruitful moments. He also presented the numbers of the event: 2,000 registered people from 985 institutions, among which 300 were foreign researchers from 40 countries. Finally, he announced that the next SBPMat annual meeting will be held in Campinas city (São Paulo state).

After the closing words, more than 20 prizes were given to young researchers within four different awards: the Bernhard Gross Award, a traditional SBPMat recognition for the best works of students, and the awards bestowed by IUMRS, E-MRS and Horiba.

Entrevistas com palestrantes de plenárias do XIV Encontro: Paul Ducheyne.

Estão presentes em dispositivos usados em procedimentos médicos amplamente praticados para diagnosticar ou tratar problemas de saúde. Fazem parte do corpo humano, de modo temporário ou definitivo, e interagem, de maneira mais ou menos ativa, com os sistemas biológicos nos quais estão inseridos. Claro, estamos falando dos biomateriais. Exemplos desses materiais são muito numerosos. Um deles é o stent que libera fármacos para conseguir melhores resultados na abertura de artérias que estão se obstruindo. Outro exemplo é o da prótese óssea que promove a regeneração do tecido natural que está substituindo temporariamente.

Biomateriais é o tema da palestra plenária do XIV Encontro da SBPMat a cargo de Paul Ducheyne. Na palestra, Ducheyne aboradrá, em particular, dois tipos de biomateriais: cerâmicas bioativas com funcionalização in situ e materiais sol-gel nanoporosos que liberam fármacos e outras moléculas.

Ducheyne é professor de Bioengenharia (a aplicação da Engenharia a questões relativas a sistemas biológicos) e de Pesquisa em Cirurgia Ortopédica, na Universidade de Pennsylvania (Penn), nos Estados Unidos. Ele também é diretor do Centro de Materiais Bioativos e Engenharia de Tecidos, um grupo de pesquisa multidisciplinar que congrega cientistas dos departamentos de Engenharia, Odontologia e Medicina da Penn.  Além disso, é professor convidado especial na Universidade de Leuven (KU Leuven), na Bélgica, onde obteve seus diplomas de MSc e PhD em Ciência e Engenharia de Materiais.

Paul Ducheyne é autor ou editor de uma série de livros sobre biomateriais; em particular, ele é editor-chefe de  “Comprehensive Biomaterials”, um livro de 3.650 páginas divididas em 6 volumes, publicado em 2011 pela editora Elsevier. Dono de um índice H de 58, ele tem cerca de 330 artigos científicos publicados com mais de 10.000 citações –  das quais umas 2.600 pertencem a seus 10 artigos mais citados. Ducheyne também é autor de mais de 40 patentes. Além disso, organizou várias conferências e simpósios da área de Biomateriais, começando na década de 1980.

Em 1992, Ducheyne fundou a empresa Orthovita, dedicada a produtos para tratar ossos lesionados e para coibir hemorragias. Foi seu presidente até 1999. Em 2011, a empresa passou a fazer parte da Stryker Corporation, uma das líderes no mercado de tecnologia para medicina.

Paul Dycheyne foi secretário da Sociedade Europeia de Biomateriais, presidente da Sociedade de Biomateriais dos Estados Unidos e da Sociedade Internacional de Cerâmicas para Medicina. Entre outros prêmios e distinções, recebeu, em 2008, o  C. William Hall Award da Sociedade de Biomateriais. Ducheyne fez ou ainda faz parte do conselho editorial de periódicos científicos das áreas de Biomateriais, Biocerâmicas, Bioengenharia, Engenharia de Tecidos, Ortopedia e Odontologia.

Segue uma entrevista com o cientista.

Boletim da SBPMat: – Conte-nos brevemente o que o levou a se dedicar aos biomateriais. 

Paul Ducheyne: – Eu sempre me interessei por medicina. Além disso, quando me formei (nos anos 70), eu já previa o declínio da indústria siderúrgica no Ocidente, e não queria ser atingido por isso. Daí veio o meu afastamento radical da ciência de materiais na época.

Boletim da SBPMat: – Como conseguiu fazer a fusão entre Ciência de Materiais e Biologia na sua carreira científica?

Paul Ducheyne: – Esse é “O” tema central da pesquisa em Biomateriais.

Boletim da SBPMat: – Quais são, na sua opinião, suas contribuições mais significativas no campo dos biomateriais? Explique-as muito brevemente e compartilhe as referências dos artigos ou livros gerados, ou comente se esses estudos geraram patentes, produtos ou empresas. 

Paul Ducheyne: – Muita gente conhece minha explicação mecanicista de como os materiais sintéticos (cerâmicos) estimulam a função celular e levam à formação de tecido.  Mais recentemente, meu uso de cerâmicos processados por sol-gel para a liberação controlada de uma variedade de medicamentos e fatores de crescimento também tem sido muito bem considerado. Por último, publiquei diversos trabalhos sobre vários assuntos (como o crescimento de tecido ósseo em materiais porosos, o comportamento mecânico do cimento ósseo e a biocompatibilidade do titânio) que são altamente citados.
