Toxicity of elemental sulfur for brucellae.
In previous reports we have described the toxicity of certain peptones and amino acids, particularly cystine, for brucellae (Schuhardt, Rode, Foster, and Oglesby, 1949; Schuhardt, Rode, and Oglesby, 1949). Subsequently, we found and reported that cystine per se is not toxic for these organims, and proved that the observed toxicity of autoclaved cystine is due to a heat-induced breakdown product...
متن کاملElemental sulfur coarsening kinetics
BACKGROUND Elemental sulfur exists is a variety of forms in natural systems, from dissolved forms (noted as S8(diss) or in water as S8(aq)) to bulk elemental sulfur (most stable as α-S8). Elemental sulfur can form via several biotic and abiotic processes, many beginning with small sulfur oxide or polysulfidic sulfur molecules that coarsen into S8 rings that then coalesce into larger forms: [For...
متن کامل11398: Investigation of Elemental Sulfur Corrosion Mechanisms
Sour gas wells frequently co-produce elemental sulfur which can cause catastrophic corrosion of mild steel. As producing wells become increasingly sour, the incidence of sulfur corrosion will likely increase. Despite the severity of this problem, limited mechanistic information about this process exists in the literature. The objective of this study is investigation of the corrosion mechanism i...
متن کاملPractical Corrosion Control Measures for Elemental Sulfur Containing Environments
This paper provides an overview of materials’ performance in well environments containing H2S and elemental sulphur (S). Based on this information the factors affecting the service life of materials used for well completion and surface facilities in highly sour environments are discussed and limitations on materials selection and chemical inhibition procedures are suggested.
متن کاملElemental-Sulfur-Mediated Facile Synthesis of a Covalent Triazine Framework for High-Performance Lithium-Sulfur Batteries.
A covalent triazine framework (CTF) with embedded polymeric sulfur and a high sulfur content of 62 wt % was synthesized under catalyst- and solvent-free reaction conditions from 1,4-dicyanobenzene and elemental sulfur. Our synthetic approach introduces a new way of preparing CTFs under environmentally benign conditions by the direct utilization of elemental sulfur. The homogeneous sulfur distri...
