Hot deformation and processing map of GH3535 superalloy

open access: yesTransactions of Nonferrous Metals Society of China, 2015
Abstract The hot deformation behavior of GH3535 superalloy was investigated by hot compression tests in the temperature range of 1000–1200 °C and strain rate range of 0.01–50 s−1. The activation energy is about 356.3 kJ/mol, and the flow curves and processing map were developed on the basis of experimental data.

Conserved structural motifs in PAS, LOV, and CRY proteins regulate circadian rhythms and are therapeutic targets

open access: yesFEBS Letters, EarlyView.
Cryptochrome and PAS/LOV proteins play intricate roles in circadian clocks where they act as both sensors and mediators of protein–protein interactions. Their ubiquitous presence in signaling networks has positioned them as targets for small‐molecule therapeutics. This review provides a structural introduction to these protein families.
