James Bray

James Bray, GE Global Research 


Title: Electrical and Electronic Materials for Industrial Applications


Abstract: This talk will focus on emerging needs, opportunities and challenges for electrical and electronic materials in energy, power conversion, aviation, lighting, and transportation, as seen from an industry perspective. There will be some emphasis on experiences at GE and on ceramics.


Biography: Bray attended Georgia Institute of Technology and was graduated with a B.S. degree in physics in 1970. He received an M.S. in physics from the University of Illinois in 1971 and a Ph.D. in physics in 1974. While at Illinois, he worked under Professor John Bardeen on unusual mechanisms for superconductivity. He joined General Electric Global Research after graduation in September, 1974. Until June 1979, he worked as a theoretical condensed matter physicist in support of several programs. Since June 1979, he has held several technical management positions supervising R&D on various physical science topics, biotechnology, electronic materials processing (e.g., molecular beam epitaxy, chemical vapor deposition), electronic devices, electronic packaging, and high-temperature superconductivity. In 1996, he began work in the new GE Six-Sigma quality thrust and eventually acted as manager of the Measurements Systems Program, containing the bulk of the NDE projects. In 1998, he became manager of the new Optical Measurements and Processing Lab, focused on applied optics projects of many types. In 2001, he became Program Manager of the Superconducting Generator Program. He presently is a Chief Scientist within Electrical Technologies and Systems.


Jurgen Rodel 

Jürgen Rödel, Technische Universität Darmstadt, Germany


Title: Lead-free piezoceramics: History, achievements, future


Abstract: Legislation originating from Europe has enhanced scientific interest in the research on lead-free piezoceramics about 10 years ago, although earlier work was done 50 years ago and some companies started research in the 1990s. Therefore I will summarize the current legislation, the progress which has been made overall in eliminating lead from industrial products and briefly review its toxicity. The evolution in research in lead-free piezoceramics over the last 20 years is then highlighted and the chances for success evaluated. In particular, progress in alkali niobates is contrasted to bismuth-based piezoceramics and barium titanate-based piezoceramics and is discussed with reference to the salient properties required. The focus will be on application-relevant properties like temperature-dependence, stress dependence, cycle and frequency dependence of the materials in question. In the end I will discuss recent advances in product development and will suggest applications where PZT may be replaced soon. As guidance for researchers, I will outline the immediate needs for the next five years and try to sketch the road for lead-free piezoceramics after that period.


Biography: Rödel is a Professor in the Department for Materials and Geoscience at Technische Universität Darmstadt (Germany). He received a Diplom in Materials Science from Universität Erlangen-Nürnberg and a Ph.D. from the University of California at Berkeley. He completed postdoc periods at NIST, Gaithersburg, and TU Hamburg-Harburg. At TU Darmstadt part of his research is focussed on processing of lead-free piezoceramics and high-temperature piezoelectrics as well as toughened piezoceramics. Next to the ceramics group, he initiated the center of electric fatigue at TU Darmstadt (SFB595). In Germany he served the Deutsche Forschungsgemeinschaft (DFG) a four-year term as speaker of the review board for Materials Science and a four-year term as regular member of same review board. Rödel is currently member of the grants committee on centers for collaborative studies of the DFG and was member of the selection committee for fellowships for the Alexander-von-Humboldt foundation. He received the DFG research award for young scientists (Heinz-Maier-Leibnitz-Price) in 1992 and the DFG research award for senior scientists (Gottfried Wilhelm Leibniz-Price) in 2009. He authored/coauthored more than 230 refereed publications and 4 patents.


Joseph Mantese

Joseph V. Mantese, United Technologies Research Center


Title: Functional Electronic Materials in Integrated Commercial Building and Aerospace Systems  


Abstract: Commercial building and aerospace platforms are undergoing a consolidation of subsystems towards creating holistic approaches to intelligent buildings and aircraft design. Using analogies from a similar rationalization of automotive systems, this talk will look at the role of functional electronic materials development and component processing as enabling technologies for future distributed sensing needs and energy generation/consumption. With an eye toward lessons learned from the automotive industry; opportunities for functional and electronic materials will be identified, particularly in the areas of: closed-loop-sensing, local power generation/storage, and material/device processing for cost-effective manufacturing.


Biography: Mantese is a Research Fellow at United Technologies Corporation’s Research Center, specializing in electronic materials, components, sensors, and packaging. Prior to joining UTRC, Dr. Mantese was Department Head of Delphi Research Laboratories (Materials, Components, and Packaging). He was Section Leader at General Motors’ Research and Development Laboratories were he received an R&D 100 Award (1997) for the development of industrial scale plasma ion implantation. He was twice winner of General Motors’ Campbell Award (1990 and 1995) for scientific breakthroughs in materials science, and is an inductee in Delphi Corporation’s Hall of Fame (2000). In 2010 Dr. Mantese received an UTRC’s Outstanding Achievement Award for his work related to multi-species chemical sensing. In 2013 he was inducted in the Connecticut Academy of Science and Engineering (CASE). Dr. Mantese is the holder of 33 patents pertaining to electronic materials, sensors, MEMS, and components. He is also the author of over 95 peer reviewed papers, a book on the fundamentals of graded ferroic materials, and three book chapters related to electronic materials and devices.
