Fernando Galembeck’s interest in research began in adolescence, when he realized the economic value of scientific knowledge while working in his father’s company in the pharmaceutical segment. Today, at age 75, Fernando Galembeck can look back at his own scientific trajectory and tell many stories about the generation and application of knowledge.
A founding member of B-MRS, Galembeck was chosen this year to deliver the Memorial Lecture “Joaquim da Costa Ribeiro” – a distinction awarded annually by B-MRS to the trajectory of a distinguished researcher in the Materials area. The honor is also a tribute to Joaquim da Costa Ribeiro, pioneer of experimental research in Materials in Brazil. The lecture, titled “Materials for a better future,” will take place at the opening of the XVII B-MRS Meeting on September 16 of this year, and will address issues such as needs, shortages and promises in the Materials area.
Galembeck graduated in Chemistry in 1964 from the University of São Paulo (USP). After getting his degree, he remained at USP working as an instructor (1965-1980) while doing his Ph.D. in Chemistry (1965-1970), in which he developed research on dissociation of a metal-metal bond. After his Ph.D., he completed post-doctoral internships in the United States, at the universities of Colorado, in the city of Denver (1972-1973) and California, in the city of Davis (1974), working in the field of Physical-Chemistry of biological systems. In 1976, back at USP, he had the opportunity to create a laboratory of colloids and surfaces at the Institute of Chemistry, in an agreement that involved the Institute, Unilever, the Brazilian Academy of Sciences and the Royal Society. From that moment on, Galembeck became more and more involved with the development of new materials, especially polymeric materials, and their manufacturing processes.
In 1980, he joined the State University of Campinas (Unicamp), after which he became a full professor in 1988, where he remained until his retirement in 2011. Since then, he has been a contributing professor at the institution. At Unicamp, he held management positions, notably vice-rector of the university, as well as director of the Institute of Chemistry and coordinator of its post-graduate program. In July 2011, he took over the newly created Brazilian National Nanotechnology Laboratory (LNNano), at the National Center for Energy and Materials Research (CNPEM), remaining in this post until 2015.
Throughout his career, he has held direction or coordination positions at the Brazilian Academy of Sciences (ABC), the Ministry of Science, Technology and Innovation (MCT), the National Council for Scientific and Technological Development (CNPq), Sao Paulo Research Foundation (FAPESP), Brazilian Chemical Society, (SBQ), Brazilian Society for the Advancement of Science (SBPC) and the Brazilian Society of Microscopy and Microanalysis (SBMM), among other entities.
Prof. Galembeck is the author of roughly 279 scientific papers published in peer-reviewed journals, with over 3,700 citations, 35 patents and more than 20 books and book chapters. He has supervised nearly 80 master’s and doctoral degrees.
Fernando Galembeck received numerous awards and distinctions, among them the Anísio Teixeira Award, from CAPES, in 2011; the Telesio-Galilei Gold Metal 2011, from the Telesio-Galilei Academy of Science (TGAS), the Almirante Álvaro Alberto Award for Science and Technology 2006, from CNPq and the Conrado Wessel Foundation; the José Pelúcio Ferreira Trophy, from Finep, in 2006; the Grand Cross of the National Order of Scientific Merit, in 2000, and the National Commendation of Scientific Merit, in 1995, both from the Presidency of the Republic of Brazil. He also received a series of acknowledgments from companies and associations, such as CPFL, Petrobrás, Union Carbide do Brasil, the Brazilian Association of Paint Manufacturers, the Brazilian Chemical Industry Association, the Union of Chemical Industry for Industrial Purposes of the State of Rio de Janeiro, Brazilian Polymer Association, Brazilian Chemical Society (which created the Fernando Galembeck Technological Innovation Award), the Union of Engineers in the State of São Paulo and the Electrostatic Society of America.
This scientist has been a fellow of TWAS (The World Academy of Sciences) since 2010 and from the Royal Society of Chemistry since 2014.
In this interview, you will be able to know a little more about this Brazilian researcher and his work.
SBPMat Newsletter: – Tell us what led you to become a scientist and work on issues in the field of Materials.
Fernando Galembeck: – My interest in research work started during my adolescence, when I comprehended the importance of new knowledge, of discovery. I found this when I was working, after school, at my father’s pharmaceutical laboratory, as I could see how the newest, latest products, were important. I also saw how costly it was, for the lab, to depend on imported raw materials, which were not produced in Brazil, and that in the country there was no competence to manufacture them. Then I realized the value of new knowledge, as well as the importance and the economic and strategic significance of such breakthroughs.
This feeling was increased when I took my major in Chemistry. I enrolled into the Chemistry course because one of my school teachers had suggested that I should seek a career related to research. He must have seen some inclination, some tendency of mine. So I attended the Chemistry course provided by the Philosophy School, in an environment where the research activity was very vivid. Because of that, I decided to conduct my Doctoral studies at USP. At that time, there were no regular graduate studies in Brazil yet. The advisor with whom I defended my dissertation, Professor Pawel Krumholz, was a great researcher, who also had built a very important career working on a company. He was the industrial director of Orquima, a major company by that time. That boosted my interest in research.
I worked with Chemistry for some years and my interest in materials came from a curious occurring. I was almost graduating, in my last vacations during the undergraduate studies. I was at an apartment, resting after lunch. I remember looking at the walls of this apartment and noticing that, with all I had learned in the Chemistry course, I did not have much to say about the things I could see: the paint, the coverings etc. That was Chemistry, but also Materials, and there was not much interest in Materials in the Chemistry course. Actually, Materials became very important in Chemistry mainly because of plastic and rubber, which, at the time, did not have the importance they have today. I’m talking about 1964, when petrochemicals were practically non-existent, in Brazil.
Well, then I started to work with Physical Chemistry, to later work a little in a field that is more oriented to Biochemistry, that is Biological Physical Chemistry and, in 1976, I received a task from the USP Department, which was to build a colloids and surfaces laboratory. One of our first projects was to modify plastic surfaces, in that case, Teflon. Then I realized that a major part of the colloids and surfaces Chemistry existed due to Materials, because the subject lends itself to create and develop new materials. From that moment on, I was getting increasingly involved with Materials, mainly polymers, a little less with ceramics, and even less with metals.
SBPMat Newsletter: – What are, in your own opinion, your main contributions to the field of Materials? Consider, in your answer, all aspects of your professional activity, including cases of knowledge transfer to the industry.
Fernando Galembeck: – I will tell the story in order, more or less. I think that the first important result in the field of Materials was exactly a technique intended to modify the surface of Teflon, that material in which it is very difficult to stick something. There is even that expression, “Teflon politicians”, the ones for which does not matter what you throw at them, they do not stick to anything. But, in certain situations, we want the Teflon to have adhesion. So, by a somewhat complicated path, I managed to see that I already knew how to modify Teflon, but I had never realized that is was important. I knew the phenomenon; I had observed it during my PhD defense. I knew that there was a change happening in Teflon. But it was during a visit to a Unilever laboratory in 1976, when I was talking to a researcher, that I saw that there were people striving to modify the surface of Teflon and achieve adhesion. Then, bringing the problem and the solution together, as soon as I returned to Brazil, I tried to see if I what I had previously observed was really useful, and it worked. That led to the first paper I wrote by myself and my first patent application, at a time when almost nobody talked about patents in Brazil, especially in the university environment. I was very enthusiastic about this: I was approached by companies that were interested in applying what I had done; one the modification in Teflon itself, the other in a different polymer. So I felt great, because I had made a discovery, I had a patent, and there were companies which, at least, would like to know what it was to see if there was a way to use it. One more thing: soon after the paper I wrote was published, I was invited to attend a conference in the United States, which addressed exactly the issue of modifying surfaces. Polymers, plastic and rubber surfaces, a subject with which I was involved for pretty much the rest of my life, up until now.
I will mention a second fact that did not have the same effects, so far. I discovered a method that enables the characterization and separation of very small particles. That was a very interesting paper. It was released, also produced a patent, but had no practical consequences. Recently, there have been some issues related to nanoparticles, which is a very important subject in Materials now, offering a chance to apply what I did over 30 years ago. The name of the technique is osmosedimentation.
Next there was some work that I did by collaborating in projects with Pirelli Cabos. With all this story of surfaces and polymers, I think I had become more or less known and was approached by Pirelli, which contracted me as a consultant and commissioned projects I had at Unicamp. An outcome of these projects, that I think is the most important, was the development of an insulator for very high voltages. This work was not only mine, but rather of a very large team, in which I took part. There were several people from Pirelli, and several from Unicamp. The result of this project was that the Brazilian Pirelli managed to be hired to provide high voltage cables for the Eurotunnel, back in the ‘80s. I think this was a very important case, as it led to a product and brought substantial economic results. I would like to stress that this was done in Brazil, by a Brazilian team. They were not a Brazilian company, but the team was based here.
Then I worked on several studies with nanoparticles, at a time when we did not even call them nanoparticles; we called them fine particles or simply small colloidal particles. The first work I published on nanoparticles was in 1978. There were other things I did next, which ultimately turned into a work on aluminum phosphate, which gave rise to several theses carried out in the laboratory and publications, and was also licensed by a company of the Bunge group, which basically exploits phosphates. The subject started in my laboratory, stayed in the laboratory for several years, then a company from the Bunge group here in Brazil became interested, started to participate, we collaborated. This became a rather large development project. Bunge later found the project unfeasible in Brazil and today it is the United States. I think it’s a pity that it is there, but there were other issues involved, including disagreements with Unicamp, which owns the patents. Recently, the company of the group that worked with these phosphates was Amorphic Solutions, which offered the product on the Internet, for various applications. From what I understand, they are currently emphasizing its use as an anticorrosive material for steel protection. I have recent information that Bunge has negotiated the rights to these products with a large chemical company, but I do not know the details.
About the same time, in another project on nanoparticles, clay/natural rubber nanocomposites were developed. This was licensed by a Brazilian company called Orbys, which released a product called Imbrik, that showed to be good for rubber rolls for paper manufacturing.
Another case with a product. I had done a project with Oxiteno, which manufactures raw materials for latex, the surfactants. They wanted to get an ideia of how much you can change the latex changing the surfactant. I conducted a project with them that I consider one of the most interesting among those in which I have been involved. In the end, we realized that, by changing the surfactant a bit, we changed the latex a lot. These are used in paints, adhesives, resins. So we realized we had a great versatility. This work was published and promoted. It did not result in a patent because it was a comprehension project. So, another company, Indústrias Químicas Taubaté (IQT) approached me to produce cationic latex, but using a new path. Cationic latex in general is made of quaternary ammonium salts, which have some environmental restrictions. The company wanted an alternative that did not have those restrictions. By the end of the project, we produced cationic latex without environmental restrictions, and the IQT put the product on the market.
My participation in a Navy project of developing carbon fibers was a great challenge that gave me big satisfaction. My group participated by synthesizing copolymers of acrylonitrile, up to the scale of ten liters. The results were transferred to a company that produced pilot scale production at the old Rhodia-Ster and Radicci plant in São José dos Campos. The selected copolymer was spun and then pyrolyzed, at the Technological Center of Marinha, in São Paulo. It resulted in a high performance carbon fiber, which was used in the manufacture of a centrifuge, used in Aramar. The challenge was to find the copolymer that showed good performance in the later stages of fiber production, which was achieved.
There was another case that was also very interesting, even though it was canceled. Here in Brazil, there was a large manufacturer of polyethylene terephthalate, PET, which is used for many things, including bottles. They knew about the work I had done with nanocomposites, the one with Orbys I mentioned before, so they approached me wanting to produce PET nanocomposites. We had to find out how to escape from what was already patented abroad and discovered a whole new path. The company was called Rhodia-Ster, and today it is part of another Italian company, called Mossi e Ghisolfi. The company was enthusiastic and ended up patenting it in Brazil, and then later abroad. At a certain point, they decided that they would conduct the work internally, and so they did for some years. One day, my contact within the company called me to tell this: “look, we were working with two technologies; the one held by Unicamp and another one, in another country. Both are working, but the company has reached a point where it has chosen to complete the development of only one”. When coming to the final stage in developing materials, the projects costs are too high. One have to use large amounts of materials, run many tests with customers. So, the company decided to take one project further, and, unfortunately, it was not the one in which I had worked. At the end, it was a little frustrating, but I think that it was interesting, because, during this whole time, the company invested a lot in the path we had started here. Not only that, each project brings resources for the laboratory, jobs at the university and the company etc. So, these projects result in many benefits, even when they are not concluded.
Now, fast forwarding, I will arrive at a more recent result of my work at CNPEM, where I was until 2015. A goal of CNPEM is the use of renewable source materials to make advanced materials. It has a whole philosophy behind it, related to the depletion of natural resources, to sustainability… The goal was to do new things with materials derived from biomass, and the main interest is in cellulose. It is the most abundant polymer in the world, but it is a very difficult polymer to work with. You cannot process pulp as you process polyethylene, for example. One of the goals is to plasticize cellulose; that is, to work the cellulose as closely as possible to the one we use to work with synthetic polymers. An initial result within this idea was the creation of cellulose adhesives in which the only polymer is cellulose itself. Then, by then no longer at CNPEM, we obtained graphite exfoliation, which generated a family of paints, pastes and conductive adhesives, which are the object of a PIPE project recently approved by Fapesp.
This is the latest case. In the middle of the way, many other projects were conducted with companies, for issues of their interest. Coating something, gluing another, modifying a polymer to achieve a certain result. But these were answers to demands from companies, instead of researches started at the laboratory.
SBPMat Newsletter: – Leave a message for our readers who are starting their careers as scientists.
Fernando Galembeck: – First of all, in any chosen career, there must be a dose of passion. It does not matter if you are going to work in the Stock Market, Healthcare or whatever you may do; above all, your taste must decide. If a person chooses a career because it will give them money or status… I think it is a bad choice. If you do things with pleasure, with interest, the money, prestige and status will come from other paths. The goal is to do what makes you happy, what makes you feel good when you do it, what makes you feel accomplished. It is true not only for the scientific career, but also to any other career. In science, it is crucial.
Another point is that you must be prepared to work hard. There is no easy way. I know some young people who are constantly seeking the great idea that will bring them success with relatively little work. Well, I’d better not count on it. It may even happen, but waiting for it is almost the same as wait to win the Lottery and get rich.
I’m over 75, therefore I have met many people and seen many things happen. Something that strikes me is how young people who seemed very promising end up not working very well. Frankly, I think it is bad for youngsters to achieve success too early, because I have the impression they get used to this idea that things will always work out fine. And the problem is that there isn’t anything, anyone, any company that will always work. There will always be the moment of failure, the moment of frustration. If the person is prepared for that, when the times come, he or she will overcome it, while others are crushed – they cannot move one. That is why we must be careful not to be deceived by our success and think that, because it worked once, it will always work. You must be prepared to fight.
When I was in college, thinking about doing research seemed a very strange thing to do, crazy talk. People did not know very well what it was, or why would someone choose to do it. Some people said that research was something like priesthood. I have always worked with research, associated with teaching, consulting and, without having ever sought to become rich, I managed to have an economic status that I deem very comfortable. But I insist, my goal was to enable the development, to produce material, not the money I would receive. Money came, as it does. So, I suggest you to focus on your work, on the results and the contribution that said work may give to other people, to the environment, to the community, to the country, to knowledge. The rest comes as a bonus.
In short, my message is: work seriously, earnestly and passionately.
Finally, I would like to point out that I think the research work, the development work, really helps you to grow as a person. It will depart you from ideas that are not very fruitful and guide you towards attitudes that are really important and helpful. A student asked Galileo once: “Master, what is the method?”, and Galileo’s answer was: “The method is the doubt”. I think it is very important in the research activity, which, for Materials in particular, is especially interesting because the final product is something you can hold in your hands. In the research activity you have to always wonder, “I’m thinking like this, but is this right?”, or “This guy wrote this, but what are his bases to write it?”. This attitude is very different from the dogmatic one, which is common in the realms of politics and religion, and very different from the attitude of someone who has to deceive, as the lawyer who works for a corrupt or drug dealer. The researchers have to commit themselves to the truth. Of course there are also people who call themselves researchers and spread disinformation. Some years ago, people were talking about something called “Bush science”, an expression referring to President Bush. This Bush science was the arguments fabricated by people who gained money as scientists, but who produced arguments to sustain Bush’s policies. In other words, the problem exists in science as well, but then we get back to what I said earlier. You cannot become a scientist because of money, or to achieve prestige, or to be invited to have dinner with the president; you must enter this field because of your interest in the subject itself.

How many scientific vocations were aroused, and how many domestic accidents were caused, by experimental chemistry games for children (which until some time ago did not follow all the toy safety standards)? The Argentine scientist Galo Juan de Ávila Arturo Soler Illia belongs to this group. He remembers that his interest in science lit up (literally) with a small fire caused by a chemistry lab set in his parents’ home – two lawyers, members of the Radical Civic Union, that was also the party of Galo Soler Illia’s grandfather, President Arturo Umberto Illia, who ruled Argentina from 1963 to 1966, until undergoing a coup.
Today, Galo Soler Illia can be considered one of the best known researchers in the Brazil´s neighboring country, both in the scientific community (he is among the 30 Argentine scientists best positioned in Google Scholar for the citations to his works, and has also received the top national science awards) and among the lay public (in the field of Nanotechnology, he is a very active and didactic presenter in all the media, and is usually an information source for Argentine journalists).
Galo Soler Illia was born in Buenos Aires on May 31, 1970. He completed his primary studies in a private constructivist school, Bayard College. In 1983, he enrolled in the National School of Buenos Aires, a public institution dependent on the University of Buenos Aires (UBA), which among other things was characterized by a high study demand, a wealth of extracurricular activities and better-quality infrastructure than other public schools. In 1988, he graduated from the college with a specialization in Sciences. Both in primary and secondary education he had the opportunity to carry out activities in science labs.
In 1989, Soler Illia began to study in a Chemistry Sciences course at UBA. During the undergraduate course, he began teaching in the Department of Physical, Analytical and Inorganic Chemistry of UBA and doing research in a group of Materials Chemistry and also in a laboratory set up in the house of a friend. In 1993, he obtained a bachelor’s degree in Chemistry, with a grade point average of 9.13 / 10.
From 1994 to 1998, Soler Illia completed his doctorate in Chemistry, also at UBA, under the guidance of Professor Miguel Angel Blesa. Through research on nanoparticles of mixed metal hydroxides, he generated knowledge about the complex mechanism of particle formation, which would be very useful in his research as a postdoc and as a professional researcher, focused on the synthesis of materials with high control of their characteristics. Concomitantly to the doctorate, he continued to teach, as an assistant, at UBA.
In 1999, he moved to France, together with his wife Astrid Grotewold, also a chemist, and remained there until 2002. Soler Illia did postdoctoral studies at the Université Pierre et Marie Curie (Paris), under the supervision of Dr. Clément Sanchez, with a 2-year scholarship from CONICET, the main Argentine entity in support of science and technology. In the post-doc, Soler Illia developed methods to produce highly controlled porosity materials. This period resulted in Soler Illia’s most cited articles so far, with more than 1,800 citations in one of the papers, according to Google Scholar. At the end of his stay in France, Soler Illia also worked on applications of mesoporous thin films for the research and development center of the company Saint Gobain.
Galo Soler Illia returned to Argentina in early 2003, at a time when the country was ending great political instability, which caused the Presidency of the Republic to appoint 5 different people in just 11 days. In addition, the country was still under the effects of the severe economic crisis that had reached its peak in 2001. However, Soler Illia was quickly able to enter the research career at CONICET, working at the National Atomic Energy Commission (CNEA) and without wasting time, founded the Chemistry Group of Nanomaterials, which to date operates in the design and development of nanostructured materials. In 2004, the scientist became a professor of UBA in the department where he studied for his bachelor’s degree and doctorate.
In early 2015, Illia became director of the Institute of Nanosystems (INS) of the National University of San Martín, located in the metropolitan area of Buenos Aires. The INS is defined as a space for nanoscience and nanotechnology research, development and creation, whose ultimate goal is to solve priority problems of industry and society in general. At the institute, Soler Illia has a multidisciplinary scientific team of 4 researchers (4 more in 2017), 6 graduate and post-doc students and 1 laboratory technician, and also a management team of 6 professionals.
Currently, in addition to being director of INS, Galo Soler Illia is principal researcher of CONICET and associate professor at UBA. He is a member of advisory boards at the Argentinean Nanotechnology Foundation (FAN) and at the Brazilian National Synchrotron Light Laboratory, and also a member of the editorial board of the Journal of Sol-Gel Science and Technology (Springer). Moreover, Soler Illia has a scientific dissemination column on Nanotechnology in a television broadcast program called “Scientists Made in Argentina”, which airs once a week on the Argentine public channel. Finally, Soler Illia has just been appointed (November of this year) as member of the Argentine Presidential Council 2030, composed of intellectuals from various fields to advise the president of Argentina, Mauricio Macri.
Soler Illia, whose h-index is 44, has produced over 120 papers published in international scientific journals, with about 11,000 citations, according to Google Scholar. He has supervised 7 completed PhD theses and is the author of 2 dissemination books on nanotechnology. He is also the author of 4 patent applications.
His work was recognized with a series of awards for science, technology, innovation and scientific popularization, among them the main Argentinean awards, like Houssay Award (2006 and 2009), from the Secretary and later Ministry of Science and Technology; the KONEX Award (2013) from the eponymous foundation and the Innovar Award (2011 and 2016) from the Ministry of Science, Technology and Productive Innovation. He also received distinctions from the National Academy of Exact Sciences, FAN, Argentinean Association of Physicochemical Research, CONICET, BGH and Dupont companies, among others. In May of this year, Galo Soler Illia was appointed titular scholar of the Argentinean National Academy of Exact Sciences, Physics and Natural Sciences, a select group of only 36 scientists.
Here’s an interview with the Argentine scientist.
SBPMat newsletter: Tell us why you became a scientist and work in the field of materials.
Galo Soler Illia: I always liked Chemistry. This started when I received a chemistry game, I was five years old, and while experimenting with it I burned my parent`s dinner table. Later, during my high school studies I was a bit of a nerd, writing software code for physics classes at my school. Writing code aroused my curiosity to know how things worked and how problems could be solved. I learned a lot. Near the end of secondary education, I decided to study Chemistry because I believed it was a very versatile and wonderful course that had great possibilities in many fields. At that time, I was really interested in Biotechnology, which was a new area. At the time I started my undergraduate studies at the University of Buenos Aires (UBA), the area of Materials Chemistry had began to emerge. Still a student, I began teaching as an assistant in the Department of Inorganic, Analytical Chemistry and Physical Chemistry of the Faculty of Exact and Natural Sciences, inspired by the example of young and enthusiastic teachers who were returning from abroad and who propagated an atmosphere of work and demand. Together with my best friends, we set up a laboratory on the terrace of one of my friend’s home. There we grew crystals and planned molecule synthesis. Since we spent all day at university and had some spare time, I found a place to work, without a salary or scholarship, in a Materials Chemistry group that had just begun. Everything was very fast, and before I noticed it I had finished my undergraduate studies and began my doctorate, manufacturing microparticles for catalysts. It was a beautiful time of my life, a time from which I still retain my innate curiosity, my willingness to explore and build materials and a wonderful group of friends, who have become outstanding colleagues now spread out throughout the world.
SBPMat newsletter: In your opinion, what are your main contributions to the Materials area, considering all aspects of your scientific activity?
Galo Soler Illia: I have always been interested in building materials, in the chemist’s task to join atom with atom, to manufacture new architectures. I focused on understanding the physicochemical phenomena that take place during the production of a material. When you know and understand these processes, you go from simply “preparing” a material to being able to design it and synthesize it, however complex it may be. And we can take advantage of the properties of the chemical elements to obtain the properties we desire. I’ll give three examples. In my thesis, I studied the precipitation and aggregation of nanoparticles of mixed metal hydroxides, precursors of catalysts. We discovered a very interesting world and were able to contribute to understanding the complexity behind a dynamic particle formation mechanism: the effects of particle shape and structure, the importance of metals coordination in the formation of a mixed phase, the evolution of surface charge and its effect on the stability of a colloid and much more, which helped me in the future as a solid basis for my research. I was fortunate to be able to work with Miguel Blesa, Alberto Regazzoni and Roberto Candal, three excellent Masters who guided me, stimulated and corrected me.
In my second phase, I worked in Paris in the laboratory of Clément Sanchez. I used what I had learned in order to develop methods to produce highly controlled porosity materials, known as organized mesoporous materials. Again, I became interested in the materials formation mechanisms, which are complex because they require controlling the growth of small inorganic species and their self-assembling with micelles. It is a small physical-chemical symphony, which one must learn to play. We had to use, develop and combine many characterization techniques to understand the phenomena taking place and how they controlled the formation and organization of pore systems, the stability and crystallinity of materials, which among others are important variables in the final performance of these solids.
In my third phase, back in Argentina, I set up a research group at the National Atomic Energy Commission in Buenos Aires, and devoted myself to building more complex architectures based on everything I had learned. My best contributions in this regard refer to the use of forces and interactions at the nanoscale to manufacture many different nanocomposites with designed and surprising optical and catalytic properties. All this required new laboratories, training human resources and the transfer of basic science to technologies. Particularly, over the last years we have worked with companies and aspire to generate nanotechnology in Argentina, extending the knowledge of our laboratory to society.
SBPMat newsletter: Briefly tell us about your interaction with Brazil. Do you come here often for collaborations, events, use of labs, seminars? Have you worked with Brazilian groups or in Brazilian laboratories?
Galo Soler Illia: I returned to Argentina in 2003 and I knew right away about what was being developed in Brazil. Since that time, I began developing projects at the National Laboratory of Synchrotron Light (LNLS), which is a beacon for all those who work in Materials in Latin America. The interaction with the synchrotron staff was very important for us to be able to characterize our materials, and we are amazed to see how the installations have improved over the years. A few months ago I had the opportunity to visit the Sirius building, which is simply stunning and which will be a world reference. I also had the opportunity to visit several universities, teaching courses and collaborating in the education of undergraduate and postgraduate students. Furthermore, we created the School of Materials Synthesis in Buenos Aires, which will have its eighth edition in 2017. This school was designed to generate a community of Latin American scientists qualified with skills in the rational synthesis of materials. We started with many Brazilian students, thanks to the support of the Argentinean-Brazilian Nanotechnology Society, which unfortunately has stopped working. It is truly beautiful to see how students from both countries work together in the laboratories and discuss and present their work in “portunhol” [hybrid mixture of Spanish-Portuguese]. From this school, and with the help of several colleagues, collaborative networks are emerging that will undoubtedly provide us with the technological base for larger joint ventures. I travel to Brazil several times a year and always admire the strength of the country to boost local technological development. I hope that after these difficult times, we may continue growing together.
SBPMat newsletter: We always ask the guest being interviewed in this section to leave a message for the readers who are beginning their scientific careers. What would you say to these junior scientists?
Galo Soler Illia: Looking back, I have three recommendations to young scientists. One is to never lose your imagination and your ability to ask questions; the second is to work hard to find the answers, and the third is to make use of the surprises. Sometimes, we train to develop a path and a strategy and we focus on the rigor to demonstrate and formalize what we find. However, it is crucial to know that this path is full of interesting nooks and turns, and sometimes an aspect we hadn’t taken into account opens up a new and unexplored landscape. Newton said that we, scientists, are sometimes like children on the beach, we find a shell that is prettier than the others and we are happy, but there lies before us the vast ocean of truth. My advice is to continually seek our shells, enjoy them and let us come within reach of understanding the wonders of our universe. And always keep in mind that developing science in our continent is a beautiful challenge that will add richness to our countries and well-being to our brothers.
Sidney José Lima Ribeiro was born in Sao Paulo (Brazil) in 1959. In high school he signed up for a technical course in Chemistry in the seaside city of Santos. He later moved to Araraquara also in the state of São Paulo where he graduated with a bachelor`s (1982), master`s (1987) and then a doctorate degree (1992) in Chemistry at the University of the State of São Paulo Júlio de Mesquita Filho (UNESP). He began his teaching career in the Chemistry Institute – UNESP in 1986. From 2001 to 2003 he was the head of the General and Inorganic Chemistry Department. In 2008, he became a full professor. His postdoctoral fellowship was in France, at the École Centrale Paris (1994) and at the Centre National d’ Etudes des Telecomunications, CNET (1995).
Professor Sidney Ribeiro is a member of the editorial board of the Journal of Sol-Gel Science and Technology (Springer) and the Journal of Non-Crystalline Solids (Elsevier) and editor of the Eclectic Chemistry journal (Chemistry Institute of UNESP).
He is the author of over 300 peer reviewed articles published in international journals, 7 books or book chapters and 19 patent applications. His scientific production has approximately 5,000 citations. He has mentored or supervised a hundred research works, including doctoral theses, master`s dissertations, postdoctoral research and scientific initiation projects.
He was a visiting researcher at the National Institute for Research in Inorganic Materials (Japan) and visiting professor at the University of Trento (Italy), at the Universities of Angers and Toulouse (France), the University of Aveiro (Portugal) and the Federal University of Juiz de Fora (Brazil).
He has been a member of the São Paulo State Academy of Sciences since 2012 and full member of the Brazilian Academy of Sciences (ABC) since 2015.
Here is a brief interview with the researcher.
SBPMat newsletter: – Tell us what led you to become a scientist and work in the Materials area.
Sidney Ribeiro: – I am a chemist. I studied a technical Chemistry course at the Carmelite High School in Santos. Afterward, by now truly enjoying chemistry, I got my Bachelor`s Degree in Chemistry here in Araraquara. I graduated in 1982. I completed my Master`s in Spectroscopy of Lanthanide here at UNESP under the guidance of Professor Ana Maria G. Massabni which included a national doctoral “sandwich” program, with a part of the work done here in Araraquara and another part at the Federal University of Pernambuco under the guidance of Prof. Gilberto Sá. In my doctoral research I started to work in the interface between Chemistry – Physics – Materials Science, in which we participate until today. My post-doctoral research was at the École Centrale Paris and CNET France Telecom from 1994-95.
SBPMat newsletter: – In your opinion, what are your main contributions to the Materials area, considering all aspects of scientific activity?
Sidney Ribeiro: – We have worked with materials containing rare earth ions with applications in photonics and biomedicine. We have two very well-cited review papers that can serve as an example for those interested in learning more about our work:
1-Carlos, LD et al, Lanthanide-Containing light-emitting organic-inorganic hybrids: a bet on the future, Advanced Materials (2009) 21(5) 509-534.
2-Correia SFH et al, Luminescent solar concentrators: challenges for lanthanide-based organic-inorganic hybrid materials, J. of Materials Chemistry A (2014) 2 (16) 5580-5596.
Our postgraduate program is classified by Capes as level 7 (the highest) and our undergraduate courses are among the best in Latin America. This basic science work has resulted in the training of skilled labor (27 master’s degrees, 20 doctoral degrees and 23 postdoctoral supervisions and dozens of undergraduate students), the deposit of 19 patent applications, and spin-offs or cooperation with a dozen small businesses that now manufacture products developed in our laboratories. The trinomial research-education-extension is definitely well explored at IQ-UNESP.
SBPMat newsletter: – Please leave a message to the readers who are beginning their scientific careers.
Sidney Ribeiro: – We are all born liking science. Who, as a child, in a moment of scientific inspiration, didn’t mix our mother’s perfume with insecticide and some olive oil just to “see what came out of it”? This taste for science has to be preserved in our educational system. And for those who are starting out I say: go ahead. The country needs you. Someone said that when you do what you love you will never “have to work”. Work becomes your pastime and it’s really awesome.
