Organic Geochemistry [Biogéohimie Moléculaire]

Abstract : Anaerobic ammonium oxidation (anammox) is a major process of bioavailable nitrogen removal frommarine systems. Previously, a bacteriohopanetetrol (BHT) isomer, with unknown stereochemistry, elut-ing later than BHT when examined by high performance liquid chromatography (HPLC), was detectedin ‘Ca.Scalindua profunda’ and proposed as a biomarker for anammox in marine...[En savoir plus]

ChemCatChem [LASYROC]

Abstract : The copper(I)‐exchanged zeolite CuI‐USY proved to efficiently catalyze the direct azidation of arylboronic acids with sodium azide under simple and practical conditions, namely at room temperature under air with methanol as solvent and without any additive. This easy‐to‐prepare and cheap catalytic material has been demonstrated to be recyclable and the mild azidation conditions...[En savoir plus]

Front. Microbiol. [Biogéohimie Moléculaire]

Abstract : Bacteria and Eukarya organize their plasma membrane spatially into domains of distinct functions. Due to the uniqueness of their lipids, membrane functionalization in Archaea remains a debated area. A novel membrane ultrastructure predicts that monolayer and bilayer domains would be laterally segregated in the hyperthermophilic archaeon Thermococcus barophilus. With very different...[En savoir plus]

Chem. Comm. [BCB]

Abstract : The measurement of exchangeable Cu2+ levels in biological samples is gaining interest in the context of copper-related pathologies. Here, we report a Tb3+ luminescent turn-off sensor for Cu2+ based on the specific and suitable-affinity Xxx-Zzz-His (ATCUN) peptide motif, enabling Cu2+ detection in the presence of a biological fluorescent background. Graphical...[En savoir plus]

Chemistry Eur. J. [LCSOM]

Abstract : The pentamethylcyclopentadienyl N‐heterocyclic carbene nickel complex [Ni(η 5 ‐C 5 Me 5 )Cl(IMes)] (IMes = 1,3‐dimesitylimidazol‐2‐ylidene) efficiently catalyses the anti‐Markovnikov hydroboration of alkenes with catecholborane in the presence of a catalytic amount of potassium tert ‐butoxide, and joins the very exclusive club of nickel catalysts for this important transformation....[En savoir plus]

Int. J. of Quantum Chemistry [LCQ]

Abstract : Two (so‐called left and right) variants of N‐centered ensemble density‐functional theory (DFT) are presented. Unlike the original formulation of the theory, these variants allow for the description of systems with a fractional electron number. While conventional DFT for open systems uses only the true electron density as basic variable, left/right N‐centered ensemble DFT relies...[En savoir plus]

La StrasNanoCar team qualifiée pour la NANOCAR RACE II

La StrasNanoCar team qualifiée pour la NANOCAR RACE II En 2021, le projet européen FET OPEN MEMO (Mechanics with Molecules) organise la 2nde course internationale de nanovéhicules : la Nanocar Race II. Il s'agit de déplacer sur une grande distance et de manière contrôlée des molécules-voitures (molécules imitant des véhicules macroscopiques) sur une piste (surface métallique) à l'aide d'un...[En savoir plus]
