sec-Alkyl radicals are key reactive intermediates in the hydrocarbon combustion and atmospheric decomposition mechanisms that are formed by the abstraction of hydrogen from an alkane, or as a second generation product of n-alkyl H-migrations, C-C bond scissions in branched alkyl radicals, or the bimolecular reaction between olefins and n-alkyl radicals. Since alkanes and branched alkanes, which...

Alkyl nitrites have been problematic worldwide due to their recreational use. Although there is a lack of scientific information on their action on the central nervous system (CNS), many anecdotal reports and case studies have inferred the CNS actions of alkyl nitrites. The objective of this study was to investigate the effects of alkyl nitrites on the CNS, especially focusing on the dopaminerg...

Based on molecular dynamics simulations, the melting points Tm of a series of 1-alkyl-3-methylimidazolium hexafluorophosphate ionic liquids [CnMIM][PF6] with n = 2, 4, 10, 12, and 14 were studied using the free energy-based pseudosupercritical path (PSCP) method. The experimental trend that the Tm decreases with increasing alkyl chain length for ILs with short alkyl chains and increases for the...

In the title mol-ecular salt, C18H22NO(+)·C7H7O3S(-), the dihedral angle between the aromatic rings in the cation is 10.00 (9)°; its alkyl side chain adopts an extended conformation. In the crystal, weak C-H⋯O and π-π [centroid-centroid distance = 3.7658 (17) Å] inter-actions link the components, generating a three-dimensional network.

significantly higher than the proposed therapeutic range of 500-1,500 ng/ml.3 Evaluation of this patient's response to bretylium suggests that a broader therapeutic range exists for the drug than previously reported. Our experience with this patient and the wide range of doses summarized above suggests that some patients may require substantially higher parenteral doses of bretylium tosylate th...

background and objectives: sodium dodecyl sulfate (sds) is one of the most widely used anionic detergents. the present study deals with isolation and identification of sds-degrading bacteria from a detergent contaminated pond situated in varanasi city, india. materials and methods : employing enrichment technique in minimal medium (pbm), sds-degrading bacteria were isolated from pond water samp...
