Microbiological analysis of the population of extremely haloalkaliphilic sulfur-oxidizing bacteria dominating in lab-scale sulfide-removing bioreactors [PDF]

open access: yes, 2008
Thiopaq biotechnology for partial sulfide oxidation to elemental sulfur is an efficient way to remove H2S from biogases. However, its application for high-pressure natural gas desulfurization needs upgrading.

Covalently introducing sulfur in a thiol-rich metal-organic framework toward advanced lithium-sulfur batteries [PDF]

open access: yes, 2023
The severe shuttle effect and sluggish reaction kinetics have hindered the commercial application of high-energy lithium-sulfur (Li-S) batteries. In this work, a dual-thiol metal-organic framework (MOF) was in situ synthesized on carbon nanotubes, and ...

Recent progress in electrochemical decomposition of hydrogen sulfide for sulfur recovery and hydrogen production

open access: yesFrontiers in Chemistry
Hydrogen sulfide (H2S) generated by industrial processes (such as petroleum refining, natural gas purification, and coal processing) is a highly toxic and corrosive gas, which is detrimental to human health and environment. Electrocatalytic decomposition

Modeling the signature of sulfur mass-independent fractionation produced in the Archean atmosphere [PDF]

open access: yes, 2014
Minor sulfur isotope anomalies indicate the absence of O2 from the Archean atmosphere. A rich dataset showing large variations in magnitude and sign of Δ33S and Δ36S, preserved in both sulfates and sulfides, suggests that further constraints on Archean ...
