The essence of nonlinear polymer rheology: everything you must know

by Shi-Qing Wang, University of Akron, USA

Polymer processing suffers from a variety of rate-limiting difficulties. In extrusion alone, we encounter surface roughness on extrudate (sharkskin), quasi-periodic extrudate distortion associated with pressure oscillation and gross melt fracture.  To have better mechanical characteristics, polyolefin resins need to have sufficiently high molecular weight, and the same is true for rubbers.  Consequently, useful polymers, in the annual amount of one hundred million tons, are always strongly entangled.  Most of the melt processing instabilities of these polyolefin and rubbers are due to the presence of high entanglement.  Our task is to understand and predict rheological responses of entangled polymeric materials.

This presentation summarizes more than one decade of intensive research carried out at Akron that has completely changed our worldview of the essence of nonlinear rheology of entangled polymers.  Continue reading “iRTG lecture series by Shi-Qing Wang (October 14, 2019) | part 1”

Polyelectrolyte Solutions: The least understood form of condensed matter

by Ralph H. Colby, The Pennsylvania State University, USA

Polyelectrolytes are polymer chains with covalently bonded ions and oppositely charge counterions. The combination of electrostatic interactions and conformational entropy of polymer chains led Nobel Laureate de Gennes to term this class of materials as the least understood form of condensed matter. Yet polyelectrolytes are essential for life, as DNA and RNA are both polyelectrolytes. Continue reading “iRTG lecture series by Ralph Colby (October 28/30, 2019) | part 2 and 3”

Two lectures on “Current trends of electronics and a study of defects in materials for semiconductor devices” (June 20/21, 2019)

by Akira Uedono, University of Tsukuba

Abstract:

In the past four decades, we have witnessed quick and large growth of the semiconductor industry, and how it has driven advances in communication, energy, health care, and security. Now it becomes the indispensable technology of our society. This great success of electronic industries was attributed to continuous and aggressive downsizing of the metal–oxide– semiconductor field-effect transistors (MOSFET). Another important achievement was light emitting diodes (LED) and semiconductor lasers based on compound semiconductors, which resulted in 2014 Nobel Prize in Physics for the development of efficient blue GaN LEDs (Akasaki, Amano, and Nakamura). Here, widegap semiconductors, especially group-III nitrides, played an important role, and they are now ready to use for power electronics, which expected to give a large impact on our society again.
