A Self-Assembled Microlensing Rotational Probe [PDF]
, 1998 A technique to measure microscopic rotational motion is presented. When a small fluorescent polystyrene microsphere is attached to a larger polystyrene microsphere, the larger sphere acts as a lens for the smaller microsphere and provides an optical ...

Glass transition and alpha-relaxation dynamics of thin films of labeled polystyrene
, 2008 The glass transition temperature and relaxation dynamics of the segmental motions of thin films of polystyrene labeled with a dye, 4-[N-ethyl-N-(hydroxyethyl)]amino-4-nitraozobenzene (Disperse Red 1, DR1) are investigated using dielectric measurements ...

Secondary Crystallization of Isotactic Polystyrene [PDF]
, 1974 When isotactic polystyrene (i-PS) is crystallized from the melt or from the glassy state at rather large supercooling an additional melting peak appears on the curve during scanning in a differential calorimeter.

Numerical Integration of Weight Loss Curves for Kinetic Analysis
Thermo, 2021 Research abounds in the literature on kinetic analyses using thermogravimetric (TG) runs. Many of these studies use approximations of integral or derivative forms of the kinetic law and all of them use programmed temperatures.
