Interviews with our plenary speakers

We interviewed Robert Chang, professor of the first department of Materials Science in the world at Northwestern University. Besides having a remarkable career as a researcher (his H index is 56), “Bob” has dedicated the past 20 years guiding the development of the Materials World Modules program, which develops educational, interactive and playful material (for example, card games) on Materials and Nanotechnology for pre-college students and their teachers. In his plenary lecture at the XIII SBPMat Meeting, Professor Chang will try to mobilize citizens of the world to solve global problems together. See our interview with the scientist.

We also spoke with Professor Colin Humphreys, a professor at the University of Cambridge.  Among other honors, the scientist was knighted by the Queen of England for his services to science. Besides being the author of over 600 publications, the professor developed materials for the industry that currently fly in aircraft engines and created low cost LEDs based on gallium nitride, material on which he specialized. In João Pessoa, he will show, among other issues, how gallium nitride could reduce electricity consumption by 25% in the world. See our interview with Colin Humphreys.

We interviewed the German physicist Karl Leo, specialist in organic semiconductors. Beyond being the author of more than 550 papers with more than 23,000 citations and 50 families of patents, the scientist has already participated of the creation of 8 spin-off companies. In his lecture at the XIII SBPMat Meeting, Karl Leo will speak on highly efficient organic devices, as OLEDs and solar cells. See our interview with Karl Leo.

We also spoke with the Portuguese physicist Antonio Luis Ferreira Martins Dias Carlos, of the University of Aveiro, who will perform a lecture in our meeting in João Pessoa on luminescence applied to nanomedicine. In the interview, the professor shared with us his most prominent works in the field of Materials. He also told us about some challenges in the area of luminescence for medical applications, both in medical imaging and intra-cellular temperature mapping, and cited examples of applications of luminescent materials that have already been used in the diagnosis and treatment of various diseases. See our interview with Luis Dias Carlos.

We interviewed the French scientist Jean-Marie Dubois (Institut Jean-Lamour), specialist in quasicrystals (ordered, but aperiodic structures on solid materials) and pioneer in patenting applications for them. He told us a little about his main contributions to the field of Materials and gave a teaser on the theme of his plenary lecture in the XIII SBPMat Meeting: he will talk about quasicrystal structures, found in metallic alloys, polymers, oxides and artificial nanostructures, and their unprecedented properties. In the picture, Jean-Marie Dubois (on the left) and Dan Shechtman, who received a Nobel Prize in 2011 for the quasicrystals, using equal ties, both decorated with the Penrose tiling, an example of aperiodicity.  Read our interview with Jean-Marie Dubois here.

We also interviewed the Italian chemist Roberto Dovesi (Universita’ degli Studi di Torino), one of the creators of CRYSTAL, a computational tool for ab initio quantum calculations used in the study of several solid materials properties. The CRYSTAL code is currently used in over 350 laboratories around the world.  In his plenary lecture in the XIII SBPMat Meeting, Dovesi will attempt to demonstrate that today quantum simulations may be very useful tools to complement experiments. See our interview with Roberto Dovesi.

We have interviewed Professor Alberto Salleo, from Stanford University, who is going to give a plenary lecture on organic electronic devices in the XIII SBPMat Meeting. Young, yet holding a career that stands out internationally, Salleo told us about the work conducted by his group, which has been developing a deeper understanding on the role provided by the defects in charge transport in organic semiconductors. He also shared with us his main papers, published in Nature Materials. Finally, Salleo discussed the next challenges and applications on organic electronics, and anticipated what he is going to address in the plenary lecture, which promises to be very informative while mild enough for a wider audience. Read our interview with Alberto Salleo.

Interviews with plenary lecturers of the XIII SBPMat Meeting: Jean-Marie Dubois (Institut Jean-Lamour, França).

The author, Jean-Marie Dubois (left) and Nobel Prize winner Dan Shechtman (right) celebrating Shechtman’s 70th birthday two years before he was awarded his Nobel Prize. Observe that both carry the same tie, which is decorated by a Penrose tiling, a prototypical example of aperiodicity in the art of drawing and painting.

The French scientist Jean-Marie Dubois, PhD in Physics from National Polytechnic Institute of Lorraine (France) is a Distinguished Director of Research at the French National Center for Scientific Research, CNRS (France), where he chairs a committee dedicated to materials chemistry, nanomaterials and processing.  He is the former director of Institut Jean Lamour in Nancy (France), a major research institute in field of materials.

His curriculum shows an international scientific trajectory. Dubois holds Honorary Doctorates (Dr Hon. Causa) from Iowa State University (USA) and Federal University of Paraïba (Brazil), is a former “overseas fellow” of Churchill College at University of Cambridge (U.K.) and a permanent visiting professor at Dalian University of Technology (China). He was recently elected as Honorary Member of Jožef Stefan Institute in Ljubljana (Slovenia). He is a member of Lorraine Academy of Sciences (France).

He is the author of more than 250 scientific articles in refereed journals, 14 international patents, and 7 books. His papers were cited more than 5400 times (H index = 39).

SBPMat newsletter: – Under your viewpoint, which are your main contributions to the field of Materials Science and Engineering? And your scientific/technological contributions with more social impact (patents, products)?

A part of 20x20x30 cm, used by a French car producer, made of a polymer reinforced by a quasicrystalline powder. It that can be produced by additive machining with no restriction regarding complexity of its shape.

Jean-Marie Dubois: – My first contribution that was aimed at a social impact was the discovery of Al-based metallic glasses, which could be good candidates for light-weight alloys useful for the aeronautic industry. I patented them in 1982, listing a number of favorable examples, and as is the rule for a patent, also counter examples. One such composition was in fact a stable quasicrystal, which was unraveled in Japan few years later. Based on this discovery, I was the first to patent few application niches of quasicrystals that are Al-based intermetallics showing no periodic order as do conventional crystals. The discovery of quasicrystals dates back to 1982, but was published in literature only in 1984, whereas my first patent on these materials was filed in 1988. From that on, I dedicated quite some efforts to discover, patent, and produce new research, about different areas of the physics of quasicrystals including thermal conductivity, adhesion and friction, corrosion resistance, etc. My leadership in this area of materials science is recognized by the international community through the “International Jean-Marie Dubois Award” that is offered every three year “to recognize important, sustained research on any aspect of quasicrystals within the 10-year period preceding the award”. Altogether, I own 14 international patents, with more than 35 extensions. I was responsaible for few tens of collaboration contracts with the industry, including a good dozen of contracts financed by the European Commissions with on average half a dozen of industrial partners and the same number of academic partners. The last one was a so-called Network of Excellence that started the field of Complex Metallic Alloys in Europe, with 20 partner institutions from 12 European countries and some 400 scientists on board.

SBPMat newsletter: – Please give us a short teaser about your plenary talk at SBPMat meeting. What do you intend to broach?

Jean-Marie Dubois: – My talk will be a laudation to the discoverer of quasicrystals who was awarded a Nobel Prize in Chemistry in 2011 for his discovery that forced the scientific community to revise its understanding of ordered condensed matter. Members of the MRS Brazil are used to know what is a crystal, a periodically ordered solid. I wish to introduce them to another type of order in solid, that is not periodic, and leads to unprecedented properties. Alloys that exhibit such a type of order are specific and I call them push-pull alloys. Then, I wish to show that this type of order is not restricted to metallic alloys, but may also be encountered in soft matter like polymers, oxides, artificial nanostructures, and even artistic drawings from ancient Islamic tilings. The talk will therefore be a review for the non-expert in quasicrystals and complex intermetallics
