A Novel Modification Method of Stainless-steel Electrode for Sulfur Preparation by Reduction of Sulfur Dioxide

Electrochemistry, 2020
A novel modification method of stainless-steel electrode for reduction of sulfur dioxide to prepare sulfur was reported. Sulfur dioxide can spontaneously react with modified stainless-steel electrode at a rate of 12.77 mA/cm2 to produce sulfur under ...

Rheological and Aging Characteristics of Polymer-Modified Asphalt with Addition of Sulfur

Engineering Proceedings, 2023
The polymer modification of asphalt binders was first introduced in Europe in the 1980s and has gained use, as lower-quality asphalt binders did not perform well under increasingly heavier traffic loading on pavements.

Isolation and evolution of labile sulfur allotropes via kinetic encapsulation in interactive porous networks

IUCrJ, 2016
The isolation and characterization of small sulfur allotropes have long remained unachievable because of their extreme lability. This study reports the first direct observation of disulfur (S2) with X-ray crystallography.

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

FEBS 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.

Produção de sulfato de amônio duplamente marcado com os isótopos estáveis 15N e 34S Production of ammonium sulfate doubly labeled with the 15N and 34S stable isotopes

Química Nova, 2005
The purpose of this work was the production of ammonium sulfate double labeled with 15N and 34S ((15NH4)2(34)SO4)), employing the ion exchange technique in two different processes. The first one was carried out using Na2(34)SO4 and (15NH4)2SO4 previously

Structural biology of ferritin nanocages

FEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...
