Low-temperature soft chemical synthesis routes to transition-metal nitrides are of interest as an alternative conventional high-temperature ammonolysis reactions involving large volumes chemotoxic NH3 gas. One such method is the reaction between metal oxides and NaNH2 at ca. 200 °C yield counterpart nitrides; however, there remains uncertainty regarding mechanism product phase assemblage (in pa...

Ternary Co3Mo3N nitrides are reported to exhibit high catalytic activity in ammonia synthesis. However, synthesis of ternary requires thermal treatments at elevated temperatures and reactive atmospheres that lead unavoidable surface reduction (∼ 10 m2 g-1). In this work, we have developed a novel approach improve the through its dispersion into area silica-based support (SBA-15). During ammonol...

This study aimed to synthesize quinolinone derivatives and investigate their cytotoxic activity. The compound 1-azacoumarin-3-carboxylic acid (2-oxo-1H-quinoline-3-carboxylic acid) was obtained via the cyclocondensation of 2-hydroxybenzaldehyde with diethyl malonate in base catalyst give ethyl coumarin-3-carboxylate, followed by ammonolysis ester (ethyl coumarin-3-carboxylate) ammonia presence ...

Study of reactor modeling in the process aniline synthesis. Every year demand for is growing all over world, and, accordingly, capacity its production. The areas consumption this product are different: production isocyanates used industry building materials (foams, decorative parts, pipe insulation, etc.), shoe industry, additives to motor fuels; pharmaceutical preparations; organic dyes and pi...

Transition metal carbides are attracting growing attention as robust and affordable alternative heterogeneous catalysts to platinum group metals (pgms), for a host of contemporary established hydrogenation, dehydrogenation isomerisation reactions. In particular, the metastable ?-MoC 1? x phase has been shown exhibit interesting catalytic properties low-temperature processes reliant on O?H C?H b...

Poly(ethylene terephthalate), more commonly known as PET in the packaging industry and generally referred to as ‘polyester‘ in the textile industry, is an indispensable material with immense applications owing to its excellent physical and chemical properties. On the other hand, due to its increasing consumption and non-biodegradability, PET waste disposal has created serious environmental and ...

Human erythrocyte ghosts were chemically cross-linked with a family of bifunctional cross-linking reagents, imidoesters. Since the reagents are identical in their chemical structures, except for the number of methylene groups, they differ by that distance between the functional groups. The maximum distance is 4.9 A in dimethyl malonimidate, 6.1 A in dimethyl succinimidate, 8.6 A in dimethyl adi...
