The demonstration of a microwave SQUID multiplexed readout of transition-edge sensor (TES) microcalorimeters has the potential to dramatically expand the scale of arrays of TESs. In this manuscript we discuss recent work to develop an instrument for high

Advances in the generalized entropy theory of glass-formation in polymer melts

December 21, 2014
Author(s)
Jack F. Douglas, J Dudowicz, Karl Freed
The generalized entropy theory (GET) of polymeric glass-forming liquids is reformulated in a simpler and more natural formalism than our previous version of this theory. This new theory is then applied to survey essential trends in the dependence of the

Solidification

December 19, 2014
Author(s)
William J. Boettinger, Dilip K. Banerjee
In this chapter, we give a general view of the formation of the solid from its melt. This process is generally driven by the extraction of heat from the melt but fluid flow has a major influence on solidification. Thus an early section deals with transport
