Public note of the the Brazilian Materials Research Society (SBPMat).
The directory and the board of the Brazilian Materials Research Society (SBPMat) express their unease in light of the lack of prospects for science, technology and innovation (STI) in Brazil. The sector has experienced deep budget cuts in recent years, cuts that threaten to derail programs and research projects and crucial advancements for the Nation. The government has shown no signs of repealing these cuts, hence ensuring a budget that can minimally maintain Brazil in the upward trajectory of recent decades.
Even more worrying is the absence of a strategic plan for STI, a key requirement to help Brazil overcome the severe crisis we are experiencing. The unification of the Ministry of Science, Technology and Innovation with the Ministry of Communications, for example, does not seem to adhere to any logic that allows us to envisage the formulation of public policies to boost Brazil’s economic and social development.
In the very short term, our suggestion is that the government should reinstate the budgets and provide the means for the ongoing initiatives of the funding agencies such as CAPES, CNPq and Finep, because the interruption or reduction of STI programs – even for short periods of time –may cause irreparable damage to Brazil.
The area that most concerns our Scientific Society is with regard to the fact that Brazil is a major producer of raw materials and lacks sufficient investment in STI to add value to products, provide high-tech companies and create jobs. It is relevant to point out that the knowledge generated in the STI activities is an essential element to build an egalitarian and developed society, which is what we aspire for our country.

People in the Materials community: interview with Rodrigo Fernando Bianchi.
In the month when the SBPMat University Chapters program completes two years of existence, we interviewed its coordinator, Professor Rodrigo Fernando Bianchi of the Federal University of Ouro Preto (UFOP), scientific director of SBPMat.
Curious since his childhood to understand the phenomena of nature, Rodrigo Bianchi chose Physics as his undergraduate major, which he studied between 1992 and 1995 in his native city, at the São Carlos Institute of Physics of the University of São Paulo (IFSC-USP). Research opportunities appeared and later he earned a master’s and doctoral degree in the area of Materials, also in the IFSC-USP, under the guidance of Professor Roberto Mendonça Faria. He received his master’s degree in 1997. In 2000, during the doctorate program, he spent six months doing research in United States, at the University of North Carolina at Chapel Hill, (a research stage known as a “doctoral sandwich” program). In 2002, he received the degree of Doctor of Science at IFSC-USP.
During his undergraduate studies, Bianchi complemented his academic activities with tutoring at USP, until he became a teacher at the Electronic Systems Engineering Department in 2004. In 2006, he became a professor in the Physics Department of UFOP. That same year he created the Laboratory of Polymers and Electronic Properties of Materials (LAPPEM). From 2011 to 2013 he was a visiting researcher at the Department of Electrical Engineering and Computer Sciences at the University of California, Berkeley, USA. Between 2013 and 2014, he was the coordinator of the Center for Technological Innovation and Entrepreneurship of UFOP.
Since the creation of LAPPEM, the research and development work carried out by the research group and collaborators of the laboratory have produced scientific papers, patents and enterprises, and have received national-level awards. For example, in 2008, the group was awarded 3rd place in the Werner von Siemens Technology Innovation Award in the “Health” modality and the Incentive Award in Science and Technology for SUS, given by the Ministry of Health for the development of neostickers. Designed for blue light phototherapy to treat neonatal jaundice, the neostickers are organic light-emitting diode sensors that indicate the optimum point of blue light accumulation for the treatment.
Another one, among the several recognitions that took place earlier this year, was a project created by LAPPEM members to introduce to the market a development conducted in the laboratory, which was classified in fourth place among 1.500 startups in Brasil in the ranking “100 Open Startups”. In this case, the product was an adhesive, also based on organic luminescent material, which allows to monitor the level of ultraviolet (UV) radiation absorbed by human skin.
Currently, and since 2014, Rodrigo Bianchi is scientific director of SBPMat. When he took over the direction, he received the assignment to create and lead the SBPMat University Chapters (UCs) program, which currently has eight participating groups based in universities of five Brazilian states. Bianchi is also dean of Planning and Development of UFOP and permanent professor of the postgraduate programs in Materials Engineering and Science: Physics of Materials.
Awarded a level 2 CNPq productivity scholarship, Bianchi is the author of 7 filed patents and more than 40 articles published in international indexed journals. He has supervised 19 master dissertations and six doctoral theses.
The following is an interview with the researcher.
SBPMat Newsletter: – Tell us why you became a scientist and what led you to work in the Materials area.
Rodrigo Bianchi: – I was always a curious child trying to understand the phenomena of nature. This “curiosity” has accompanied me throughout my journey as a scientist, from the basic and secondary cycles, through my studies in Physics in the Institute of Physics of São Carlos, USP, and postgraduate studies in Materials Science and Engineering, also at USP, up to the research lines that I coordinate at UFOP, in polymeric electronic devices applied to healthcare. The research opportunities in polymers I had since my undergraduate years led me to work closer in the applied area. As a result, from Physics I went to Materials Science and Engineering, and today I consider myself a “physicist – materials engineer” with research lines focused on both the fundamental study of charge transport phenomena in organic electronic devices, as well as the idealization of sensors applied to neonatology, to the food area and to the monitoring and control of radiation.
SBPMat Newsletter: – In your assessment, what are the main contributions to the Materials area? Please also tell us of the cases in which you participated to transform scientific knowledge into products.
Rodrigo Bianchi: – Without a doubt I believe that the main contribution was to use the phenomena that made organic electronic devices not feasible for the market, such as photodegradation, that led to low durability and poor performance of organic light emitting diodes (OLEDS), to develop innovative sensors. Something like knowing the principles of operation and limitation of devices that were still in the maturation phase to create new sensors with different applications. An example of this strategy was the use of color change of the OLEDs, generated by the exposure of oxygen and light, which precluded many of the commercial applications of these systems, to develop colorimetric radiation sensing in the form of nanofibers, films and gels. In other words, develop 1, 2 and 3D scale sensors to use in different health areas: from phototherapy control for neonatal jaundice to monitoring UV radiation for sunbathers and construction and rural workers, up to the monitoring of cobalt processes, radiotherapy and food irradiation. So, encouraged by such research, partnerships and guidelines, besides our group in UFOP, there are currently other research groups working in the area in Brazil and abroad. Furthermore, our group is currently composed of physicists, chemists, food engineers, pharmacists and many students and professionals focused on developing multidisciplinary research in the field of organic electronics. The group has generated dozens of articles, patents and guidelines, with a focus to always understand the fundamental phenomena in order to develop innovative organic devices. Due to this characteristic, our team members have been awarded important innovation awards, as for instance by the Ministry of Health, Siemens and the Government of the State of Minas Gerais.
From a technological point of view, the As31 startup, created by students to market these products, was recently in fourth place in the ranking of the 100 Open Brazilian Startups, and regularly meets with major companies to establish B2B partnerships (business-to-business) to launch products into the market. This was the second startup created by members of our research group. The lesson we learned is that there are many difficulties related to creating technological and innovative products. Therefore, the first step to launch a startup involves having a well-trained and competent scientific and technological team. However, having the courage to change and modify the direction of the company is fundamental. For example, today the As31 has two Smart Tags as driving-force products: one to indicate to the consumer possible raw meat contamination processes, caused by temperature variations during its shelf-life, and another to indicate when bathers, especially children, should reapply sunscreen. two applications that emerged from the observation of the problems of OLEDs for more than ten years and which are currently very up to date.
SBPMat Newsletter: – The SBPMat University Chapters (UCs) program, which you have coordinated from the beginning, celebrates its two year anniversary this month. Give us your personal assessment of the results achieved to date and tell us about your plans for the program going forward.
Rodrigo Bianchi: – About the SBPMat UC program, I have to say it has been a great pleasure to participate in this creation and in the work done. It’s a challenge and not an easy task setting up a work routine and the involvement of students who are the future of the materials area in the country. We now have materials groups spread out and concentrated in all regions of the country, from north to south, from east to west. Then, it is very important to unite these students in a single cause, and as a result provide them their value in society. How to do this? Our strategy was to encourage students to form their groups, and this included numerous lectures and disseminations of UCs across the country. Once the UC program were created, most important thing was to encourage students to organize a symposium at the annual SBPMat meeting, in which students had a leading role in society by getting involved in establishing the program and also in organizing the event. An innovation, because I don’t know of any other materials entity that has provided such an opportunity until now. This happened in Rio de Janeiro in 2015 and the involvement and success of the students was clearly seen. These were high-level scientific lectures involving not only materials science themes, but also ethics and scientific writing, for example. In other words, themes that interest directly the students, who are the future of the Materials area in the country. For the next meeting in Campinas, the students are organized to again coordinate this symposium. Regarding the future? The answer is to encourage the formation of new groups, interaction among students and consolidate the participation of everybody in SBPMat.
SBPMat Newsletter: – We always ask the person interviewed in this section of the newsletter to leave a message for those who are beginning their scientific careers. Would you like to say something in particular to these future scientists / junior scientists?
Rodrigo Bianchi: – As a final message to the readers, especially the younger ones: “the Materials area is extremely rich and gives us the opportunity to interact with various themes and professionals from many fields of knowledge. So, enjoy this significant feature. Get involved with competent and motivating people, and have the courage to innovate and bring your ideas into the market. Brazil needs this and you can make a difference!”

SBPMat´s community people: interview with Roberto Mendonça Faria.
The interviewee of this edition of the newsletter of the Brazilian Materials Research Society Newsletter (SBPMat) is Professor Roberto Mendonça Faria, who has just handed over the SBPMat Presidency after four years in office (although he promises to remain active in the society).
Roberto Mendonça Faria was born in Adamantina, a small town on the west side of the State of São Paulo (Brazil), on May 1952. At the beginning of his secondary studies, already oriented towards “hard sciences” and stimulated by a great physics teacher, he started to look at science as a potential profession. In 1976, Faria concluded his bachelor’s degree in physics at the São Paulo University (USP).
In the same year, still passionate about physics, in which humanity was taking great steps towards knowledge, Faria began his academic career. He started teaching in undergraduate courses at USP and began his master´s course in physics at the same university. There, supervised by Professor Bernhard Gross, a pioneer in Materials research in Brazil, Faria learnt the pillars of scientific activity and developed a fascination for uncovering mysteries of materials (in this case, the conductivity induced via radiation in a polymer known as Teflon). Right after obtaining the master’s degree, in 1980, Faria began the doctorate course in physics at USP, once again having Professor Gross as supervisor. In 1984, Faria defended his dissertation about dielectric absorption and induced conductivity via radiation in the polymer PVDF.
In 1985, Faria started lecturing in postgraduate courses at USP. Between 1987 and 1989, he stayed in France on a post-doctorate internship at Université Montpellier 2. In 1990, he obtained the Associate Professor title at USP after defending a thesis about phase transitions in ferroelectric copolymers. In 1999, he became Full Professor of the São Carlos Institute of Physics (IFSC) at USP, where he occupied several management positions throughout the years, such as the head of the Department of Physics and Materials Science (1994-1996), the coordination of the postgraduate program in physics (1997-1998) and the IFSC general direction (2002-2006).
Roberto Faria also was the coordinator of two large scale projects at a national level. The first project was the “Multidisciplinary Millennium Institute of Polymeric Materials”, one of 17 projects selected within the program “Institutes of the Millennium” of the Brazilian Ministry of Science, Technology and Innovation (MCT). This institute gathered around 140 researchers from 17 institutions from Brazil’s five regions, and existed between 2002 and 2008. The second project continued one of the research focuses of the first one – the study of electronic polymers and their applications. Starting in 2009, the Brazilian National Institute for Organic Electronics was approved and established in the context of the Brazilian National Institutes of Science and Technology (INCTs) from the MCT.
Going beyond the frontiers of his scientific area, Faria was the coordinator, between 2010 and 2014, of the São Carlos pole of the Institute of Advanced Studies (IEA) at USP, an organization intended for broad and interdisciplinary research and discussion of fundamental issues on science and culture. In addition, in the context of his interest in contributing with the economical development of his country through research, Faria coordinated the making of the book “Science, technology and innovation for a competitive Brazil”, published in 2012.
In the last few years, Faria has been having an active participation in international scientific entities in the Materials area. In 2014, he was one of the general coordinators of the “Spring Meeting of the European Material Research Society – 2014”, which took place in the French city of Lille. In 2015, he was elected second vice-president of the International Union of Materials Research Societies (IUMRS).
Faria is a member of the Academy of Sciences of the State of São Paulo and the Brazilian Academy of Sciences and belongs to the editorial board of the journal “Materials Science – Poland”. In 40 years of scientific research on polymeric materials, particularly those with electronic activity and their applications in devices, Professor Faria has produced around 180 articles published in indexed journals, having about 2,000 references, and has supervised 47 master´ss and doctorate thesis.
An interview with the researcher follows below.
SBPMat Newsletter: – Tell us what made you become a scientist and work in the field of Materials.
Roberto Mendonça Faria: – Before High School, I imagined I was going to follow my studies in the “hard sciences” area (engineering, physics, chemistry, mathematics, etc.). But I didn’t have any intention to follow a scientific career, even less so to be a scientist. However, in the first year of High School I started to change my mind, stimulated by an excellent physics teacher, Roberto Stark. I graduated in Physics and soon after I was lucky to be supervised by two great masters: Professor Bernhard Gross and Professor Guilherme Fontes Leal Ferreira. As any newly-graduated person in physics at the time, I was passionate about the extraordinary experimental and theoretical advances of the 20th century physics. However, my first research study was about an apparently modest theme: the interaction of ionizing radiation with thin films of insulating polymers. Under the supervision of Professor Gross, I definitely learnt how to approach a scientific issue and also how to handle the methodological strictness needed to discover the effects and the phenomena arising from the experiments performed. Those first years of research were crucially important to my career. I never again lost the fascination in discovering the properties and the enigmas of the condensed matter, and I’m happy because materials science and engineering is extremely important for the development of Brazil.
SBPMat Newsletter: – In your assessment, which are your main contributions to the field of Materials?
Roberto Mendonça Faria: – There are different ways to measure the contributions made to the advance of scientific and technological knowledge. The most objective and internationally followed view is the bibliometric, conduced by the Journal of Citation Reports (JCR) from Thomson Reuters. This metric has many merits, but it’s too much focused on numbers. Another fact influencing scientific assessments comes from the pragmatism of the present world. Today, it is required that scientific works aim at specific applications. In this context, researches involving more fundamental studies tend to lose the visibility they deserve. That is, many times scientific works of great value have little mentions. An analysis of my production from JCR may lead to the conclusion that my most relevant contributions are connected to applications, but I particularly believe that my greatest contributions are more related to fundamental works in the areas of phase transitions of ferroelectric polymers and electrical transportation mechanisms in electronic polymers.
One of the interesting areas I have been working on in the last few years is the organic solar cells. I believe that, with my research group, we gave a significant contribution to the understanding of phenomena involving the transportation of electrical carriers inside the cell. Since 2013 we published two works where we developed an analytical equation which rules the electrical current curve in function of the voltage of a solar cell when under lighting. This analytical equation works very well in special cases and has explained many of the optoelectronic effects of the devices we built and measured in our laboratories. One of the works was published in the Applied Physics Letters journal in 2013, and the other was published on Solar Energy Materials and Solar Cells in 2015.
On the other hand, I always dedicated myself to assembling research laboratories and forming human resources. I also have been contributing with several post-graduation programs, directly and indirectly, and for more than 20 years I have been dedicating myself to strengthening the area of Organic Electronics in the country, especially in the formation of a research network in this area: the National Institute of Science and Technology of Organic Electronics. Whenever possible, I try to encourage projects in partnership with private enterprises and research institutes that aim towards applied projects. In the public policies area, I believe my greatest participation was coordinating a document from CAPES (the Brazilian agency in charge of post-graduate programs) and SBPC (Brazilian Society for the Advancement of Science), called “Science, technology and innovation for a competitive Brazil”, which has contributed to the creation of the Brazilian Company of Industrial Research and Innovation (EMBRAPII).
SBPMat Newsletter: – You have just finished your tenure as President of SBPMat. Share with our readers an analysis of the results achieved by the boards you have headed during the last four years.
Roberto Mendonça Faria: – SBPMat is a relatively new society, but it has an important mission to fulfill for the development of the country. Brazil has an extraordinary richness offered to it by nature. However, the country does not take advantage of this richness because it places little knowledge over its natural resources. There was a revolution in agriculture after the country decided to put knowledge over this blessing that nature has offered to it. Today, agribusiness is one of the pillars, perhaps the strongest one, of our economy. We have to do the same with the raw matters that abound in our territory. The publication “Science Impact – A special report on materials science in Brazil”, in partnership with the Institute of Physics (IOP), was one of the projects that worked and gratified me very much. This type of initiative helps raising awareness that Brazil has a natural gift to be a leader in several materials-related segments and to generate a lot more richness than it currently does.
Another valuable contribution that the two previous SBPMat administrations gave to materials science and engineering in Brazil was the definite consolidation and internationalization of the annual meeting, which always take place at the end of September.
I must highlight that the creation of the bilingual electronic newsletter was a realization that worked, especially because of the capability it has been produced with.
SBPMat Newsletter: – You just took over, for two years, the second vice-presidency of IUMRS. Talk about your plans, expectations…
Roberto Mendonça Faria: – I’m starting this activity. My plans are, first of all, to increasingly insert the Brazilian Materials Science in the international scenario. At the same time, I intend to use the IUMRS support to stimulate materials research in other Latin American countries. Brazil and Latin America have many problems that come from their still deficient economies. I have conviction that research studies in the materials area are valuable instruments to improve the living conditions of these populations. Today, as a member of the SBPMat council, I want to take this discussion not only in Brazil, but in several Latin American countries with the help from IUMRS.
SBPMat Newsletter: – Leave a message for the readers that are starting their scientific careers.
Roberto Mendonça Faria: – I decided to register here that one of the fulfillments (still in progress) that makes our administration proud was the creation of the University Chapters program. I’m going to ask the council to allow me to work with Professor Rodrigo F. Bianchi within this program. I have no doubts that the more researchers we form, the more Brazil will gain with this.
I believe that the work with young people starting scientific activity is one of the most valuable works for a senior researcher. It is our duty to show young people how important the work of “manufacturing knowledge” is for the country, especially in scientific and technological areas. There isn’t one example of a country that has eradicated poverty without the development of strong education and competitive science and technology. Therefore, the message to young people is: believe in your work and always try to make it in the most competent way possible.
XV SBPMat Meeting: deadline for submission of symposia proposals was extended up to February 11.

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.
