Measurement of Thermo-Optic Properties of Thin Film Dielectric Coatings [PDF]

, 2013
We have carried out an experiment to test the theory of the thermo-optic response of a dielectric stack mirror coating and to measure parameters of interest in calculating thermo-optic noise. Specifically, we measured the coefficient of thermal expansion

Dielectric-tensor reconstruction of highly scattering birefringent samples

, 2022
Many important microscopy samples, such as liquid crystals, biological tissue, or starches, are birefringent in nature. They scatter light differently depending on the light polarization and molecular orientations.

A non-obtrusive technique to characterize dielectric charging in RF-MEMS capacitive switches

, 2012
Degradation and failure due to dielectric charging has been a dominant and pervasive reliability concern for RF-MEMS switches. Traditionally, the operational lifetime dictated by this degradation phenomenon is extrapolated from a series of measurements ...

Application of terahertz spectroscopy to the characterization of biological samples using birefringence silicon grating [PDF]

, 2012
We present a device and method for performing vector transmission spectroscopy on biological specimens at terahertz (THz) frequencies. The device consists of artificial dielectric birefringence obtained from silicon microfluidic grating structures. The

C2α‐carbanion‐protonating glutamate discloses tradeoffs between substrate accommodation and reaction rate in actinobacterial 2‐hydroxyacyl‐CoA lyase

FEBS Open Bio, EarlyView.
Enzymes of the 2‐hydroxyacyl‐CoA lyase group catalyze the condensation of formyl‐CoA with aldehydes or ketones. Thus, by structural adaptation of active sites, practically any pharmaceutically and industrially important 2‐hydroxyacid could be biotechnologically synthesized. Combining crystal structure analysis, active site mutations and kinetic assays,
