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

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.
