Biography

Professor Emri has developed an innovative theoretical-experimental approach to studying the interrelation between the macroscopic thermo-mechanical boundary conditions and the rate of structural rearrangement which is related to the mechanical spectrum. He has developed several unique, specially designed apparatuses for characterization of time-dependent behavior of materials. Among them the high-pressure apparatus for experimental studying of the simultaneous effects of pressure and temperature on the structure formation and non-linear behavior of polymeric materials is probably the most important. The non-linear viscoelastic model Knauss-Emri, the Emri-Tschoegl algorithm for the evaluation of mechanical spectra, and the high-pressure apparatus represent a unique tool for studying the interrelation between the so-called initial molecular kinetics (determined with the molecular mass distribution and topology of molecular chains), the thermo-mechanical boundary conditions, and the macroscopic properties of polymer materials. In collaboration with BASF, this experimental-theoretical approach was used in the development of new generation nano-structured polymers, which were named the I-Polymers (where I stands for intelligent). The invention was patented world-wide. These nano-structured materials exhibit orders of magnitude different physical properties than the chemically identical conventional polymers. One book and chapters in 4 books, over 150 publications, 23 patents (international, US and EU), more than 30 invited and plenary lectures on conferences, universities and research institutes, and about 1000 citations in peer reviewed journals and books.
