Miquel Salmeron Biography

Miquel Salmeron graduated in physics from the University of Barcelona and obtained his PhD from the Autonomous University of Madrid, Spain. He is currently a senior scientist at the Lawrence Berkeley National Laboratory, in the materials science division, which he directed until August 2012. He is also adjunct professor in the materials science and engineering department at the University of California, Berkeley. His research focuses on the structure, reactions and mechanical properties (friction, lubrication) of materials surfaces and nanomaterials. He pioneered the development of scanning tunneling microscopy for studies of materials surfaces in vacuum and in atmospheric pressures of gases and liquids. He also developed x-ray photoelectron spectroscopy for studies under gases at ambient pressures. His interests include the atomic scale origin of friction, nanoparticle structure and reactivity, solid-electrolyte interfaces for energy storage applications and electronic properties of organic films. He received the Outstanding Research and the Outstanding Scientific Accomplishment Awards from the U.S. Department of Energy in 1995. He is a fellow of the American Physical Society since 1996 and of the American Vacuum Society since 2003. In 2008, he received the Medard Welch Award of the American Vacuum Society and the Langmuir Lectureship Award of the American Chemical Society.

Talk Presentation: Physics and Chemistry of Material Surfaces under Ambient Conditions of Gases and Liquids—What’s New?

The atoms at the surface of materials are the frontier separating the bulk from the surrounding medium. Over the last decades scientists have studied intensely the structure and properties of the surfaces with the goal of understanding and improving electronic and chemical properties of materials. This is because the surface–medium interaction determines wetting, friction, chemical, biological and electronic properties. The activity of catalysts, the phenomena occurring in water droplets and particles in the atmosphere and the electronic properties of semiconductor devices are direct consequences of surface-environment interactions. While the need to pursue studies in the normal environment that surrounds a material, that is, under gases or liquids, has always been recognized, the techniques used in the past have only partially fulfilled this need, as they work best under high vacuum conditions. My research over the last ten years has focused on discovering what are the surface structures and their dynamics in real life, everyday environments, an endeavor that often required the development of new techniques and methods. I will present some of the new tools developed in my laboratory and what new properties were discovered with their application to study phenomena in the area of environmental science, surface chemistry, electrochemisty and catalysis.

Jennifer Lewis Biography

Jennifer A. Lewis joined the faculty of the materials science and engineering department at the University of Illinois at Urbana-Champaign in 1990 where she is currently appointed as the Hans Thurnauer Professor of Materials Science and Engineering and serves as the director of the Frederick Seitz Materials Research Laboratory. In 2013, she will join the faculty of the School of Engineering and Applied Sciences and the Wyss Institute for Biologically Inspired Engineering at Harvard University. Her research group has made pioneering contributions to the directed assembly of soft functional materials. To date, her work has resulted in over 120 peer-reviewed papers and eight patents. She has served on the editorial advisory boards of Langmuir and Soft Matter and as an associate editor for the Journal of the American Ceramic Society. Lewis is the recipient of the NSF Presidential Faculty Fellow Award (1994), the Brunaeur Award from the American Ceramic Society (2003) and the Langmuir Lecture Award from the American Chemical Society (2009). In addition, she is a fellow of the American Ceramic Society (2005), the American Physical Society (2007), the Materials Research Society (2011) and the American Academy of Arts and Sciences (2012).

Talk Presentation: Printing Functional Materials

The ability to pattern functional materials in planar and three-dimensional forms is of critical importance for several emerging applications, including flexible electronics and photovoltaics, lightweight structural materials and tissue engineering scaffolds. Direct-write assembly enables one to rapidly design and fabricate materials in arbitrary forms without the need for expensive tooling, dies or lithographic masks. Recent advances in the direct-write assembly of viscoelastic inks will be highlighted, including pen-on-paper electronics, electrodes for flexible photovoltaics and conformal 3D antennas, printed origami metallic and ceramic structures and 3D hydrogel scaffolds and microvascular architectures for tissue engineering. Ongoing efforts to enable high-throughput printing of large-scale architectures will also be described.
