Himanshu Jain

Prior to joining the faculty of Lehigh University in 1985, Dr. Jain worked as a researcher for six years at the Materials Science Division of Argonne National Laboratory, and the Nuclear Waste Management Division of Brookhaven National Laboratory. During this period he also taught a graduate course on ceramics at Columbia University in New York City and served as a Visiting Scientist at UniversitÑt Dortmund, Germany and Indian Institute of Technology at Kanpur, India. At Lehigh he has introduced new courses on Dielectrics, Glasses, and Biomaterials. Dr. Jain's research activities include: dielectric properties, defects, diffusion, and nuclear spin relaxation in glasses and ceramics; physical and chemical structure of glass; radiation enhanced processing; glass-metal reactions; materials problems in nuclear waste management; etc. He is a discoverer of 'anomalous isotope mass effect in glass'. Professor Jain has edited three books and is a coauthor of two patents and numerous research papers. He is a recipient of Humboldt and Campbell Fellowships. He maintains active collaborations with several institutions in Germany, Greece, India and U.S.A. This goes well with him as he enjoys visiting new places in his spare time.

Selected recent publications

An understanding of interaction of reactive metals with common oxide glasses is crucial to their application in hermetic seals, microelectronics, as a biomateri al etc. The figure shows the microstructure of the development of the interface between titanium metal and silica glass. The inset is a high resolution x-ray ph otoelectron spectra describing the very early stages of the reaction between the two components at room temperature, which cannot be detected by common analytic al techniques.

Inorganic glasses are used in numerous electrical, microelectronics and optical applications. Dr. Jain's group has specialized in correlating physical and chemi cal structure with electrical properties. The 3-D figure shows the electrical re sponse of an ion conducting glass over a wide range of temperature and frequency . The large plane represents a relatively new mechanism of conductivity describe d by Dr. Jain as the 'jelly fish' like movement of a group of atoms.

Prof. Jain and his daughter have recently produced a paper that describes the making of hard candy as a model for the processes involved in commercial glass formation. The full version of this paper is available here in PDF format (3.1 MB).
