A 59-year-old man was referred by his family doctor for progressive renal failure. He was on lithium sulfate therapy since 32 years for bipolar disorder. The medical history revealed polyuria and polydypsia, which was persistent since several years. Family history was negative for hereditary nephropathies. Laboratory findings revealed a blood urea nitrogen concentration of 7.0 mmol/l and a seru...

one-pot preparation of 2,4,5-trisubstituted and 1,2,4,5-tetrasubstituted imidazoles has been conducted in the presence of poly(4-vinylpyridinium butane sulfonic acid) hydrogen sulfate, p(4vpbsa)hso4, as an efficient dual acidic catalyst under solvent-free conditions. reusability of the catalyst, easy work-up procedure, eco-friendly reaction conditions, short reaction times and high yields of th...

Extensive lithium wall coatings and liquid lithium plasma-limiting surfaces reduce recycling, with dramatic improvements in Ohmic plasma discharges in the Current Drive Experiment-Upgrade. Global energy confinement times increase by up to 6 times. These results exceed confinement scalings such as ITER98P(y,1) by 2-3 times, and represent the largest increase in energy confinement ever observed f...

The dissolution kinetics of silica-containing minerals in aggregates influences strongly the process ASR concrete. In this paper, effect different ions on rates SiO2 (amorphous and quartz) feldspars at high pH values was studied by following increase silicon concentrations experiments with a novel approach measuring evolution scratches polished surfaces. second method avoided problem precipitat...

In the title dihydrate salt, 2C12H24N(+)·SO4 (2-)·2H2O, the cation possesses twofold rotational symmetry, with the N atom situated on the twofold axis. The sulfate anion has fourfold roto-inversion symmetry, with the S atom located on the -4 axis. In the crystal, the components are linked via ammonium-sulfate N-H⋯O and water-sulfate O-H⋯O hydrogen bonds, forming a three-dimensional network.

A novel deltaproteobacterial, mesophilic, hydrogen-oxidizing, and sulfate-reducing bacterium (strain KaireiS1) was highly enriched from an inactive chimney located in the active zone of Kairei hydrothermal vent field (Central Indian Ridge) Ocean. Based on 16S rRNA gene analyses, strain KaireiS1 is currently only cultured representative a cluster uncultured Deltaproteobacteria, positioned within...

The sulfate-reducing bacterium Desulfovibrio vulgaris Hildenborough possesses four periplasmic hydrogenases to facilitate the oxidation of molecular hydrogen. These include an [Fe] hydrogenase, an [NiFeSe] hydrogenase, and two [NiFe] hydrogenases encoded by the hyd, hys, hyn1, and hyn2 genes, respectively. In order to understand their cellular functions, we have compared the growth rates of exi...

A convenient and efficient direct protocol for the preparation of antibacterial azo dyes by the reaction of 2-naphthol with aromatic amines in the presence of catalytic amount of N-methyl-2-pyrrolidonium hydrogen sulfate ([H-NMP]HSO4) was carried out under solvent free conditions. This method has some advantages such as: easy work-up and easy separation of catalyst from the reaction mixture. Th...

Beyond state-of-the-art lithium-ion battery (LIB) technology with metallic lithium anodes to replace conventional ion intercalation anode materials is highly desirable because of lithium's highest specific capacity (3,860 mA/g) and lowest negative electrochemical potential (∼3.040 V vs. the standard hydrogen electrode). In this work, we report for the first time, to our knowledge, a 3D lithium-...
