The Role of Hydrogen Sulfide in Evolution and the Evolution of Hydrogen Sulfide in Metabolism and Signaling [PDF]
Physiology, 2016 The chemical versatility of sulfur and its abundance in the prebiotic Earth as reduced sulfide (H2S) implicate this molecule in the origin of life 3.8 billion years ago and also as a major source of energy in the first seven-eighths of evolution. The tremendous increase in ambient oxygen ∼600 million years ago brought an end to H2S as an energy source,

Thermally Induced Gelling Systems Based on Patchy Polymeric Micelles
Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.A novel strategy to design thermally induced gelling systems with tunable material properties is reported. Polymeric mixed‐shell micelles displaying multiple thermosensitive patchy domains formed hydrogels by assembling into well‐entangled worm‐like network structures upon heating to body temperature. The patchy micelle design significantly affects the

Metabolic Turnover of Hydrogen Sulfide [PDF]
Frontiers in Physiology, 2012 More than 15 years have passed since hydrogen sulfide (H2S) emerged as a biological signaling molecule – initially, in the nervous and vascular systems through the modulation of N-methyl d-aspartate (NMDA) receptors and the activation of transmembrane receptor potential (TRP)- and ATP-dependent K+ (KATP)-channels (Abe and Kimura, 1996; Hosoki et al ...

Which Chromium–Sulfur Compounds Exist as 2D Material?
Advanced Functional Materials, EarlyView.2D chromium sulfides synthesized using molecular beam epitaxy on graphene. Structural characterization reveals two novel 2D materials, Cr2S3‐2D, which lacks a direct bulk counterpart, and Cr223S${\rm Cr}_{2\frac{2}{3}}{\rm S}$4‐2D, a minimum thickness version of Cr5S6. However, attempts to synthesize CrS2 are unsuccessful. Both new 2D phases are stable

Terahertz spectroscopy of hydrogen sulfide [PDF]
Journal of Quantitative Spectroscopy and Radiative Transfer, 2013 Abstract Pure rotational transitions of hydrogen sulfide (H2S) in its ground and first excited vibrational states have been recorded at room temperature. The spectrum comprises an average of 1020 scans at 0.005 cm−1 resolution recorded in the region 45–360 cm−1 (1.4 to 10.5 THz) with a globar continuum source using a Fourier transform spectrometer ...
