In the first step, the base (OH⁻) will deprotonate the ethanol, generating an alkoxide ion (C₂H₅O⁻). This alkoxide ion will then attack the carbonyl carbon of acetone, leading to the formation of ahemiacetal(or hemi-ketal in this case). The reaction can be summarized as foll...
Transiently trapped quantum states along the reaction coordinate in the transition-state region of a chemical reaction are normally called Feshbach resonances or dynamical resonances. Feshbach resonances trapped in the HF–OH interaction well have been d
Lipase was used as positive control, while samples without the reaction mix were used background controls. Cu(I)-catalyzed azide-alkyne cycloaddition reaction (Click-iT chemistry) Cells were grown on coverslips in a 12-well plate and kept either with FASNi, 0.2 µM or with vehicle (...
Real-time quantitative RT-PCR (qRT-PCR) reactions were performed in 20 μL solution with a LightCycler480 SYBR Green I Master (Roche) according to the manufacturer instructions. Each reaction was performed in triplicate. The mRNA expression level of the validated genes (CDK9, BNIP3L and ZC...
A safe and scalable procedure for the synthesis of 2-oxopropanethioamide, an intermediate in the synthesis of a potent β-secretase (BACE-1) inhibitor, from the reaction of acetyl cyanide with hydrogen sulfide gas under continuous-flow conditions has been developed. The toxic gas could be accura...
富氧空位(In3+)掺杂TiO2 (Vo - In -TiO2)对NO3−和CO2共活化还原合成尿素表现出较高的催化活性,相对于可逆氢电极(vs. RHE),在−0.65 V电位下,法拉第效率(FE)和尿素产率(Rurea)分别为9.06%和759.8 μg mg−1h−1,这可归因于氧空位(Vo)和In3+各自的功效及其通过接力催化(relay catalysis)的协同...
[80]. Staudenmaier improved this method by adding the chlorate in small portions throughout the reaction [81]. The process is slow and involves the generation of the toxic gas(es) NO2, N2O4, and/or ClO2; the latter also being explosive [82]. Hummers and Hoffman introduced the most ...
The title compounds were obtained by reaction of Zr(OnPr)4) with an excess of the corresponding acids and analyzed by single crystal X-ray diffraction. Each cluster consists of a Zr6O4(OH)4 core in which the faces of a Zr6 octahedron are capped by μ-OH or μ-O groups, while the...
Oxygen evolution reaction catalysts capable of working efficiently in acidic media are highly demanded for the commercialization of proton exchange membrane water electrolysis. Herein, we report a Zn-doped RuO2 nanowire array electrocatalyst with outstan
Test media preparation. The corrosive environment was HCl 1 M, prepared by the dissolution of 37% hydrochloric acid in double-distilled water. Various concentrations of the inhibitor (0.1, 0.2, 0.3, 0.4, 0.5, and 1.0 mM) were prepared by suitable dilution in 1 M HCl. Weight ...
