Edward Van Keuren, Ph.D.

Georgetown University

Edward Van Keuren is an Associate Professor in the Department of Physics at Georgetown University. After obtaining a Ph.D. in Physics from Carnegie Mellon University in 1990, Prof. Van Keuren worked for the German chemical company, BASF AG, in Germany and Japan, and also spent several years at the Japanese National Institute of Materials and Chemical Research. During this time, his work encompassed the development and characterization of novel optical switching materials, in particular those based on organic nanoparticles. He also developed a number of fiber optic light scattering methods for determining particle size in concentrated dispersions. Since 1999, he has been at Georgetown, continuing his research on the preparation and application of nanoparticles. His research focus is on both applying novel optical characterization methods to measure the nucleation and growth of organic nanoparticles in solution as well as the development of new nanoparticle-based materials for applications such as MRI contrast enhancement. He has over 80 publications in peer reviewed journals, several patents, and his work has been recognized by a National Science Foundation Career Enhancement Award, an Oak Ridge Associated Universities Ralph E. Powe Junior Faculty Enhancement Award.

Jaime Ruiz García, Ph.D.

Universidad Autónoma de San Luis Potosí

DNA is a highly charged polyelectrolite and as such it is considered to be completely soluble in pure water. Surprisingly, we found that DNA can be trapped at the air/water interface and does not go back into a pure water subphase. We show that DNA is trapped in a minimum energy at the interface, much bigger that KT, that does not permit its return to the bulk. Once at the interface, DNA molecules condense to form different two-dimensional mesostructures such as foams, giant rings, disks and rods at low density. This condensation occurs without the presence of multivalent cationic ions, as it is required in bulk, for example in condensing DNA toroids. However, we show that monovalent and divalent cations do not change this behavior, but trivalent cations does. At high density, the molecules form a remarkable monomolecular network. At the interface, DNA is only partially immersed in water, which originates that the chains get only partially charged, but the charges are of the same sign. Therefore, this can be considered another case of like-charge attraction, similar to those found in colloids trapped at the air/water interface. However, the origin of the attractive part of the interaction potential is unknown. In addition, we found that DNA at the air/water interface can form 2D smectic-like domains tens of microns in size. Both, the DNA monomolecular networks and the smectic-like domains are interesting from theoretical and application standpoints.

Jesús Israel Mejía Silva, Ph.D.

Israel Mejia, received his BE in Electrical Engineering with distinctions from the National Polytechnic Institute in Mexico City in 2003. After achieving a Ph.D. from CINVESTAV in 2010, he joined the University of Texas at Dallas (UTD) as a Research Scientist for the department of Materials Science and Engineering. As a key link between academia and industry, Dr. Mejia’s work primarily involves leading research teams in using innovative approaches to design, fabricate and characterize semiconductor devices for implementation in novel, cutting-edge microelectronic applications, integration processes and circuits. He was awarded as IEEE Senior Member in 2016 and he has been heavily involved in technology development for startups and large multinational semiconductor companies. He is currently the Director of Microtechnologies at CIDESI hosting the Micro Electronic and Mechanical Devices Laboratory. Novel thin film transistors (TFTs) have become a cost-effective alternative technology to be used in applications where conventional single crystal materials are not functional. Such applications involve systems capable of being flexible and transparent, rugged and lightweight, large area and cheap. However, some of these “novel TFTs” do not offer the required performance for a specific applications or the processes are not ready to be transferred to standard manufacturing processes commonly used in industry. Therefore, adequate strategies are required in research groups to keep a balance between “basic science” and “applied science” if they are to be successfully engaging projects attractive for potential applications that benefit society, while at the same time fostering fundamental science for students. In this talk, we will discuss the methodology and the key drivers that led to the implementation of the polysilicon TFT node. We will discuss in detail the technological challenges associated with moving out of the “comfort zone” for scientists and students. Finally, we will demonstrate the benefits and the outcomes this new node has to offer for the academy-industry relationship.
