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.

FRET Measurement of Polymer Response under Shear
Sensors, 2021 Polymer solutions under shear flow are often observed in manufacturing processes. Classically, polymer behavior is represented by Kuhn’s bead-spring model, in which only the elongation of polymer chains is assumed.

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 ...
