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 ...

Organic sulfur: A spatially variable and understudied component of marine organic matter

open access: yesLimnology and Oceanography Letters, 2020
Sulfur (S) is a major heteroatom in organic matter. This project evaluated spatial variability in the concentration and molecular‐level composition of organic sulfur along gradients of depth and latitude.

Effects of organic sulfur on oxidation spontaneous combustion characteristics of coking coal

open access: yesEnergy Exploration & Exploitation, 2022
Research on the spontaneous combustion of coal caused by sulfur has always been focused on pyrite in coal but has rarely considered the influence of organic sulfur.

Sulfur-bound biomarkers of a Monterey shale and a Greenland lake sediment [PDF]

open access: yes, 2009
Seeking to reconstruct the biogeochemical processes that produced organic sulfur compounds in two unique depositional environments, we used the nickel boride desulfurization reaction to release hydrocarbons from sulfur-bound macromolecules not otherwise ...

Doses of sulfur at topdressing and organic compost supply at planting in the production, quality and content of macronutrients in lettuce seeds

open access: yesBioscience Journal, 2022
The purpose of this study was to evaluate doses of sulfur applied at topdressing, with and without organic compost supply at planting, in the production, physiological quality and content of macronutrients in lettuce seeds.

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 ...

Extractive Distillation Approach to the Separation of Styrene from Pyrolysis Gasoline Feedstock Coupled with Deep Desulfurization

open access: yesSeparations, 2023
The separation of mixtures with close boiling points is a critical task in the petrochemical industry, and one such mixture that requires separation is o-xylene/styrene.

Chemical and Isotopic Evidence for Organic Matter Sulfurization in Redox Gradients Around Mangrove Roots

open access: yesFrontiers in Earth Science, 2019
Coastal environments like mangrove forests are increasingly recognized as potential hotspots for organic carbon burial, giving them a crucial and yet poorly constrained role in the global carbon cycle.

Chemotaxonomic patterns in intracellular metabolites of marine microbial plankton

open access: yesFrontiers in Marine Science, 2022
Most biological diversity on Earth is contained within microbial communities. In the ocean, these communities dominate processes related to carbon fixation and nutrient recycling.

Effects of elemental sulfur and sulfur-bearing minerals on the thermal evolution of aromatic compounds in solid bitumen

open access: yesShiyou shiyan dizhi, 2021
Previous studies have shown that some of the aromatic compound parameters have good correlation with the maturity of organic matter. However, it is still unknown whether the widely used aromatic maturity-related parameters are available with the co ...
