Connecting high-temperature and low-temperature protein stability and aggregation

PLOS ONE, 2017
Protein aggregation is a long-standing problem for preservation of proteins in both laboratory settings and for commercial biotechnology products. It is well established that heating (cooling) can accelerate (slow) aggregation by populating (depopulating) unfolded or partially unfolded monomer states that are key intermediates in aggregation processes.

Temperature dependence of the superheating field for superconductors in the high-k London limit

, 2008
We study the metastability of the superheated Meissner state in type II superconductors with k >> 1 beyond Ginzburg-Landau theory, which is applicable only in the vicinity of the critical temperature.

The temperature stabilization and temperature measurement of a Kösters interferometer

Measurement Science and Technology, 2005
In this work, the mechanical design, optical setup and temperature measurement system of a Kosters interferometer are described for the length measurements of long gauge blocks. The temperature variation of 9 mK at 15 °C and 2 mK at 20 °C was measured inside the interferometric chamber using the six air and four surface thermistors.

Analysis of the Light Propagation Model of the Optical Voltage Sensor for Suppressing Unreciprocal Errors

Sensors, 2017
An improved temperature-insensitive optical voltage sensor (OVS) with a reciprocal dual-crystal sensing method is proposed. The inducing principle of OVS reciprocity degradation is expounded by taking the different temperature fields of two crystals and ...
