Despite all the knowledge on nanotechnology generated over the last few decades, applying nanomaterials to commercial products can still be a difficult task. At the XVI B-MRS Meeting, Professor Pulickel Ajayan, one of the world’s references in nanomaterials and nanostructures, will shed light on this problem. In the plenary lecture he will address in Gramado on the morning of September 14, Ajayan will discuss some challenges of the application of nanomaterials (particularly those of two dimensions) in systems and devices. He will address issues related to the synthesis, characterization and modification of these materials.
Ajayan and his collaborators have developed nanomaterials with diverse functionalities, applicable to fileds such as energy storage and conversion, catalysis, low consumption electronics, nanomedicine or environment care. Among his most famous contributions, are carbon nanotubes filled with molten material acting as nanowire moulds (1993); nanobrushes made of carbon nanotubes, highlighted by Guinness World Records as the smallest ones (2005); the paper battery, made of cellulose and nanotubes (2007); the ultra-dark nanotube carpet, which reflects only 0.045% of light (2008), and a reusable sponge of nanotubes capable of absorbing oil dispersed in water (2012).
Professor and director of the Department of Materials Science and Nanoengineering at Rice University (USA), Ajayan has exceptional publication metrics: a h index of 144 and more than 95,000 citations according to Google Scholar.
Pulickel Madhavapanicker Ajayan was born in 1962 in India, in a small town in the southern state of Kerala. He attended primary school there and then went to the state capital, to a high school that aroused his enthusiasm for learning, his curiosity, and his interest in science.
In 1985, Ajayan graduated in Metallurgical Engineering at Banaras Hindu University (BHU), located in northeastern India and then went on to do a PhD in Materials Science and Engineering at Northwestern University (USA). At that moment, he began to penetrate nanotechnology. In 1989, he defended his PhD thesis about very small gold particles that, some years later, would begin to be called “nanoparticles”.
In 1990, he moved to Japan to pursue a postdoctoral stage at the Fundamental Research Laboratory of the NEC Corporation, where he remained until 1993 in the group that was responsible for a series of seminal studies on carbon nanotubes – including the “discovery” of these nanomaterials, attributed to Sumio Iijima in 1991. During his postdoc, Ajayan obtained important results on the synthesis of nanotubes in large scale and on the filling of nanotubes with other materials.
From Japan, he went to France where he worked as a researcher at the Solid Physics Laboratory of the Université Paris-Sud for two years. Then he went to Germany, where he worked for a year and a half at the Max-Planck-Institut für Metallforschung. In 1997, he moved to the United States to become an assistant professor at the Rensselaer Polytechnic Institute (RPI), the nation’s oldest university of technological research, located in the state of New York. At RPI, he was the Henri Burlage chair Professor in Engineering and worked in the nanotechnology research group.
In 2007, he left RPI and joined the faculty of the Department of Mechanical Engineering and Materials Science at Rice University to be the Benjamin M. and Mary Greenwood Anderson professor of Engineering. In 2014, he also held the founding chair of the Department of Materials Science and NanoEngineering.
Currently, in addition to teaching and leading a research group of about 40 members at Rice University, Ajayan travels a lot, whether to share his knowledge on nanotechnology (he has delivered more than 350 invited lectures and has held visiting professor positions at universities around the world), or to take care of his scientific collaborations. In addition, Ajayan has acted on the boards of several journals, startups and international conferences of the materials and nanotechnology field.
The scientist has received important awards from a number of institutions including the Royal Society of Chemistry (UK), Alexander von Humboldt Foundation (Germany), Materials Research Society (USA), Microscopic Society of America (USA). He also received distinctions of numerous universities around the world, including the doctorate honoris causa by the Université Catholique de Louvain (Belgium). He is an elected member of the Royal Society of Chemistry (UK), American Association for the Advancement of Science (AAAS), and the National Academies of Sciences of India and Mexico, among other scientific societies.
Here follows an interview with the scientist.
B-MRS newsletter: – We would like you to choose some of your contributions to nanotechnology, describe them briefly, and share the paper reference, if possible. Please choose:
– The one(s) you consider to have caused or will cause more social impact.
Pulickel Ajayan: – Several of our discoveries have commercial and social impact. In the past two decades some of the research highlights from our lab have been carbon nanotube arrays as extreme light absorbers (for thermo-photovoltaics), nanotube arrays as gecko-tapes, high conductivity carbon nanotube fibers, graphene oxide membranes for water filtration, carbon nanomaterials for energy storage, light weight polymer nanocomposites, development of two-dimensional materials for electronics and sensors, carbon based quantum dots as catalysis for example CO2 reduction etc.
– The one(s) that gave you more personal satisfaction.
Pulickel Ajayan: – One of the most exciting work was related to the conversion of carbon onions into diamond nanoparticles using electron irradiation. This work was done in collaboration with Prof. Florian Banhart when I was visiting as a post-doc at the Max Planck Institute for Metallforschung in Stuttgart in the mid-90’s. This work published in Nature magazine showed direct observation of graphite to diamond phase transition without application of any external pressure.
B-MRS newsletter: –Have any of your scientific/ technological contributions been transferred to a commercial product? If so, has this transfer occurred through patent licensing, start-up …?
Pulickel Ajayan: – Two start-up companies (Paper Battery Co. and Big Delta Systems) have come out of our work; both engage in unconventional energy storage technologies.
B-MRS newsletter – Leave an invitation to your plenary talk for our readers.
Pulickel Ajayan: – Nanotechnology is a paradigm changing approach on how we will be building materials of the future. It is at the core of bottom-up manufacturing and will impact several areas of future technologies. Our work in the past two decades have focused on creating nano-engineered materials with various types of nanoscale building blocks.
Besides repelling water, superhydrophobic materials can be useful in a myriad of applications. Anti-ice, anti-corrosion and anti-bacterial systems, oil/water separation, water purification and desalination, and drug delivery are just a few examples. At the XVI B-MRS Meeting, this wide range of possibilities will be presented in a plenary lecture by Professor Frédéric Guittard.
Together with his research group at the University of Nice Sophia Antipolis (France), Guittard gets inspiration from nature to create hydrophobic and oleophobic surfaces based on conductive polymers and other materials. In these topics, the group has dozens of patents and articles (seven of them, highlighted in the covers of journals of Chemistry, Polymers and Materials since 2014), and is among the few most cited groups in the world.
Frédéric Guittard obtained his doctoral degree in Organic Chemistry in 1994 from the University of Nice Sophia Antipolis, and remained in the institution as a postdoc for about a year. Between 1995 and 1996, he carried out postdoctoral internships at institutions in the cities of Padua (Italy), Preston (United Kingdom) and Prague (Czech Republic). From 1996 to 1997, he worked in the pharmaceutical industry in the Principality of Monaco.
In 1997, he returned to his alma mater, the University of Nice Sophia Antipolis, as an associate professor, becoming a full professor in 2002. From 2004 to 2010, he was the director of the university’s Chemistry Department. Concerning laboratory leadership, Guittard coordinated the Laboratory of Chemistry of Organic and Metallic Materials and, since 2017, leads a new laboratory, the N.I.C.E. ®, whose name refers not only to its location in the city of Nice, but also to the acronym of “Nature Inspires Creativity Engineers”. In addition, Guittard created, and already directs, a professional master’s degree program in Materials and Management at the University of Nice.
In 2012, 2014 and 2016, Guittard was the chairman of the first editions of the international conference on materials inspired by nature, also identified with the trademark N.I.C.E.
Currently, Guittard is a visiting professor at University of California, Riverside (USA).
His scientific production, which has more than 5,200 citations, includes books, more than 230 articles and 35 patents.
Here follows an interview with the scientist
B-MRS Newsletter: – Your research has a biomimetic approach. In what elements of Nature do you take inspiration to develop your hydro and oleophobic materials?
Frédéric Guittard: – From an artichoke. My kids wanted me to grow an artichoke: when I watered it, surprisingly I rediscovered the Lotus effect. The next steps were to adapt, to adopt, to integrate this secret from Nature into technologies or biotechnologies.
B-MRS Newsletter: – In your opinion, what are your main scientific or technological contributions in the field of hydrophobic and oleophobic materials? Please describe them briefly, and share the paper reference, if possible.
Frédéric Guittard: – There are some interesting applications for superhydrophobic or superoleophobic materials. The main applications concern the anti-adhesion (like anti-graffiti, anti-icing, anti-fingerprints …) or anti-bioadhesion (like anti-fouling or for example to remove bacteria from surfaces in hospitals). The following publications will give more details:
– Bioinspired Superhydrophobic Surfaces: Advances and Applications with Metallic and Inorganic Materials, CRC Press, Francis & Taylor Group, 300 pages, 2017 (F. Guittard, T. Darmanin)
– Superhydrophobic and Superoleophobic Properties in Nature, Materials Today, 2015, 18, 273-285 (T. Darmanin, F. Guittard)
– Recent advances in the potential applications of bioinspired superhydrophobic materials, Journal of Materials Chemistry A, 2014, 2, 16319-16359 (T. Darmanin, F. Guittard)
B-MRS Newsletter: – Your laboratory has an extensive list of industrial partners. Is university-to-industry knowledge transfer common in your laboratory? If so, in what way does it happen? Via patent licensing, spin-offs, joint projects?
Frédéric Guittard: – The first point is to understand that Industries and Universities are not competitors but can form a chain of value. In this way, the industries have to innovate in order to improve or to create the service. The Universities can help the industries to show amazing solutions with a proof of concept. Even if the cost is important to take into account, the key point at 80% for success is the good human relationship. More often, the solution is near us and the effort is weak! We have to see and to observe in order to find the key parameter and to ask the question where is the best in class from all the phenomena in the world (not only in the same field). It is like the benchmarking approaches.
Patent, licensing, spin-offs or joint projects can be used according to the origin of the idea and its realization.
In the research group of Professor Kirk Schanze, conjugated polyelectrolytes (CPEs) have been the subject of both fundamental studies and applications. The group has already explore CPEs as fluorescent sensors, in solar cells and as biocidal materials.
On September 13, in Gramado, Kirk Schanze, who is a Professor at the University of Texas at San Antonio (UTSA) and editor-in-chief of ACS Applied Materials & Interfaces, will take some time out of his busy schedule to deliver a plenary lecture on CPEs in the XVI B-MRS Meeting.
Schanze graduated in Chemistry from Florida State University in 1979. Four years later, he earned his Ph.D., also in Chemistry, from the University of North Carolina at Chapel Hill. Soon after, he was appointed a Miller Postdoctoral Fellow at the University of California, Berkeley. In 1986, he joined the University of Florida (UF) as a professor of the Department of Chemistry. There, he chaired the Division of Organic Chemistry, held the Prominski Chair of Chemistry, and founded the Schanze Group, which today continues its research activities at UTSA. In 2016, Schanze left UF to hold the Robert A. Welch Distinguished University Chair in Chemistry at UTSA.
Between 2000 and 2008, Schanze served as senior editor of the prestigious journal Langmuir. Shortly thereafter, he became the first editor-in-chief of ACS Applied Materials & Interfaces, which had just been released.
Prof. Schanze has authored about 300 papers and 20 patents. According to Google Scholar, his scientific production has more than 16,000 citations and his h index is 71. He is fellow of the American Chemical Society (ACS). He was a visiting professor at the Harbin Institute of Technology (China) and the Tokyo Metropolitan University (Japan) in 2011, at the Ecole Normale Supérieure Cachan (France) in 2008 and at the Chemical Research Promotion Center (Taiwan) in 2007. He has received distinctions from the American Chemical Society, National Science Foundation, University of Florida, Japan Society for Promotion of Science, and Japanese Photochemical Association, among other entities.
Here follows an interview with the scientist.

Kirk Schanze: – Everyone is invited to attend my talk which will highlight our work of conjugated polyelectrolyte as applied in the field of energy- and bio- materials chemistry.
In the race to develop ever smaller and better performing chips, several technological limitations need to be overcome. Today, the bottlenecks to continue this trend lie mainly in techniques for manufacturing electronic circuits of less than 10 nanometers (nm). Among the techniques being improved to manufacture the next generation of chips, one of the most promising is extreme ultraviolet lithography (EUVL). This technology takes advantage of the very short wavelength of extreme ultraviolet radiation to pattern nanoscale circuits on the chip with the intermediation of the so-called “resists” – thin layers of radiation sensitive material that cover the chip substrate during nanofabrication.
At the XVI B-MRS Meeting, a plenary lecture will discuss an important contribution that the materials field can make to the next generation of chips: the development of suitable resists for the fabrication of electronic circuits of less than 10 nm through EUVL.
The subject will be presented by Kenneth E. Gonsalves, Distinguished Professor of the Indian Institute of Technology Mandi (IIT Mandi), a teaching and research institution created in 2009, where Gonsalves arrived in 2012 as a visiting professor.
Gonsalves obtained his BS in Chemistry from the University of Delhi (India) followed by an MS also in Chemistry from Boston College (USA) and a PhD from the University of Massachusetts at Amherst (USA) with a doctoral thesis on polymer synthesis. Then he performed a postdoctoral specialization on polymer ceramics at MIT (USA). From 2001 to 2014, Gonsalves was the Celanese Acetate Distinguished Professor of Polymer Materials at the University of North Carolina at Charlotte (USA).
Together with his research group at IIT and his collaborators from the United States, India, Brazil, Taiwan and Europe, Gonsalves carries out research and development on resists for advanced nanofabrication techniques, with support of major companies in the electronics segment, and on polymer scaffolds for tissue engineering.
Here follows a brief interview with the researcher.
B-MRS newsletter: – Tell us a little bit about your main scientific/ technological contributions up to the moment.
Kenneth Gonsalves: – My research has centered on polymers with an emphasis on synthesis of novel materials. For the last 20 years I have focused on resist technology for IC (integrated circuit) fab. This is a fascinating area as it has significant technological applications in the development of integrated circuits, solid state devices. In addition it can also be used successfully for cell and tissue engineering of scaffolds for biotechnologies.
B-MRS newsletter: – About the resists you are working on, what skills and expertise are needed to develop them, in your opinion? When this next generation of chips is expected to be available?
Kenneth Gonsalves: – Resist R&D is multifaceted and extremely complex. It requires extensive collaborations between chemists with organic, inorganic and polymer backgrounds. In addition, interaction with physicists and electrical/electronic engineers is essential. The next generation of chips at the 14 nm node are currently available. Sub 7 nm node technology is expected by 2018 onwards.
B-MRS newsletter: – Describe in the simplest and briefest possible way the process of EUVL, without forgetting to mention the role of resists.
Kenneth Gonsalves: – The EUV photons are generated by a plasma or synchrotron source operating at a wavelength of 13.5 nm. Through a series of special mirrors and a mask, the predesigned template for the IC fab is projected onto photosensitive materials such as polymers as well as inorganics. This is all conducted in vacuum, a challenge for the IC fab industry as it is a drastic change from current photolithography fab, which functions under ambient conditions. The extremely short EUV wavelength is a prerequisite for patterning features at the sub 20 nm scale. The challenges for resists that can meet the sub 7 nm node requirements are enormous. A new paradigm is paramount – hybrid resists, that are partially inorganic may provide solutions to patterning at these scales. Inorganic hardmasks are another alternative. The sensitivity of these photoresists has to be enhanced drastically in order to meet the mass volume production of chips. There are several other critical parameters that have to be met for a successful resist system. Again, this requires multidisciplinary, multi institutional, industry collaboration on a global scale.

B-MRS was present at the 69th annual meeting of the Brazilian Society for the Advancement of Science, represented by Professor Glaura Goulart Silva (UFMG), scientific director of our society. Learn more about Goulart Silva’s impression of the event (“an area of resistance to the dismantling of science and technology in Brazil”) and her account on the round table on carbon nanostructures, in which she participated as a panelist. See here.
In a study carried out at the Brazilian Federal University of Triângulo Mineiro, researchers developed a mortar reinforced with multilayer graphene nanoflakes, with resistance almost 150% higher than that of traditional mortar. The material may be easily prepared by civil construction professionals by adding graphene powder to conventional mortar. The scientific team also studied the mechanisms that provide exceptional resistance to this new material.

Interviews with speakers of the XVI B-MRS Meeting
We interviewed Professor Susan Trolier-McKinstry, who is the current president of the Materials Research Society (MRS) and the Steward S. Flaschen Professor of Ceramic Science and Engineering at Penn State (USA). Trolier-McKinstry is also a Professor of Electrical Engineering and Director of the Nanofabrication facility at that university. The scientist will deliver a plenary lecture in Gramado, on September 12, on piezoelectric films for microelectromechanical systems (MEMS). Based on piezoelectric materials, Trolier-McKinstry and her group have developed MEMS – microscopic machines capable of capturing and processing environmental information, and with this data, carrying out operations involving movement – with applications in the energy and health areas, among others. In the interview, she spoke about science and about the current challenges of materials research societies. See the interview.
We also interviewed Alexander Yarin, Distinguished Professor at the University of Illinois at Chicago (USA). In his plenary lecture in Gramado, on September 11, he will talk about the nanofibers he produces in his laboratory from agro-waste materials, using a process based on the interaction between a jet of polymer solution and a jet of air. These biopolymer nanofibers can be used in health and environmental areas, for example. Find out more about Professor Yarin’s main contributions and about the themes he will address at the XVI SBPMat Meeting. See the interview.
