Abstract:
Lithium-sulfur batteries appear to be an exciting technology for energy storage due to their many advantageous properties. Due to its low weight and high energy, this technology could be used in aviation, aerospace or in heavy electric vehicles or even for mobile applications. This article investigates possible approaches for modelling of lithium-sulfur batteries. A new method using Ansys Fluent add-on Multi-Scale Multi-Domain battery module, originally designed for lithium-ion batteries, is presented. Battery characteristics are described through an equivalent circuit model, which can capture

Abstract:
The nutrient status and fertiliser requirements of a red earth soil (Gn 2.14) were examined in glasshouse and field experiments in northern Queensland. From soil analyses and glasshouse experiments, deficiencies of phosphorus, potassium, sulfur and zinc were expected. However, the only nutrients limiting growth of Stylosanthes scabra cv. Seca pastures under field conditions were phosphorus and sulfur. In the first 2 years of the field experiments, applications of 20 kg/ha of phosphorus and sulfur (equivalent to 220 kg/ha of single superphosphate) gave near maximum response in DM yield of Seca.

We have previously reported morphological correlates of sulfur mustard (HD) toxicity in several model systems: the human skin grafted athymic nude mouse; the hairless guinea pig; and human cells in culture. We are now describing HD effects in a human skin equivalent, TESTSKIN®, and comparing these effects with those already reported for animal models and cells in culture. The human skin equivalent (HSE) is used here as an organotypic in vitro model system to bridge the knowledge gap between HD effects in monotypic cells in culture and animal in vivo effects.

Abstract:
Two-dimensional (2D) layered thiophosphates have garnered attention for advanced batteries due to their open ionic diffusion channels, high capacity, and unique catalytic properties. However, their potential in energy storage applications remains largely unexplored. In this study, we report for the first time a 2D transition metal thiophosphate (Nb4P2S21) with high sulfur content. Nb4P2S21, synthesized via chemical vapor transport (CVT), is treated as a sulfur-equivalent material with better conductivity than sulfur, suitable for high-capacity lithium storage.

S-Adenosylmethionine (SAM), likely an ancient molecule in biological systems, is known for delivery of a [CH3+] equivalent to a host of cellular metabolites containing nucleophilic N, O, S, and C centers via heterolytic cleavage of the CH3–S bond in SAM. SAM can also undergo catalyzed hemolytic cleavage of that CH3–S bond by iron/sulfur-containing enzymes that use the resultant 5′-deoxyadenosyl radical for carbon-based radical chemistry on specific substrates. Bioinformatic analysis indicates >50 000 such enzymes in microbial data bases. All these iron/sulfur cluster enzymes are predict

The paragenetic sequence is complex, involving multiple generations of sulfide ore minerals. Early minerals are disseminated throughout the host rock.

Abstract:
Dyeing leather is an important process, because visual perception is the first experience that a customer or anyone else has of the material: the colour itself, the intensity and the uniformity. Traditionally, vegetable-tanned leather was coloured by natural products, which required the assistance of a mordant. The development of chromium(III) tanning followed the development of synthetic dyes, which offered deeper shades. Currently, the commonest class of dyes for leather is the 1 : 1 premetallised dyes, the equivalent of a strong colourant carrying its own mordant. Other classes of dyes are

S-Adenosylmethionine (SAM), with the unique thermodynamically activated but kinetically stable trivalent sulfonium cation in its side chain, is the second most widely used coenzyme after ATP. SAM can engage in a multitude of two-electron paths, where transfer of the methyl group as a nascent cation equivalent to O, N, S, and even carbon nucleophiles dominates natural product tailoring flux. The aminobutyryl group of SAM is also activated at C4 as an electrophilic carbon. Equally important, if not more so, in natural product biosynthetic pathways are one-electron redox routes where SAM, coordin

Abstract:
Unlike other group transfer reactions in biochemistry, the actions of nitrogen transferring enzymes do not follow a single unifying chemical principle. Nitrogen-transferring enzymes catalyze aminotransfer, amidotransfer, and amidinotransfer. An aminotransferase catalyzes the transfer of the NH2 group from a primary amine to a ketone or aldehyde. An amidotransferase catalyzes the transfer of the anide-NH2 group from glutamine to another group. These reactions proceed by polar reaction mechanisms. Aminomutases catalyze 1,2-intramolecular aminotransfer, in which an amino group is inserted into an
