Biocatalysts, capable of efficiently transforming CO2 into other more reduced forms of carbon, offer sustainable alternatives to current oxidative technologies that rely on diminishing natural fossil-fuel deposits. Enzymes that catalyse CO2 fixation steps in carbon assimilation pathways are promising catalysts for the sustainable transformation of this safe and renewable feedstock into central ...

Various strategies have been proposed to promote sustainable incomes through good urban governance. One of the good strategies for good urban governance is the development of sustainable tourism in order to achieve sustainable urban incomes. Tourism as the second industry plays an important role in the cycle of economic activity, employment development, currency and tax revenue, and compensatio...
The kinetics and mechanism of oxidation of cetirizine hydrochloride by Mn(VII) in acidic medium was studied spectrophotometrically. The electron transfer reaction between MnO4 and the drug have been studied over the range 2.0 ≤ 10 [cetirizine hydrochloride] ≤ 6.0, 2.5 ≤ pH ≤ 4.5 and 295 K ≤ T ≤ 313 K in aqueous medium. The electron transfer reaction shows first order dependence in [MnO4 ] T and...

Reaction of substituted-aniline (8) with ethyl (l-methyl-5-nitroimidazole-2- carbonyl) acetate (9) gave 4-hydroxy-2-(l-methyl-5-nitro-2-imidazolyl)- substituted-quinolines (lo), which were converted to compound 11 with phosphorus oxychloride. Substituted-2-(l-methyl-5-nitro-2-imidazo1yl)-4.- methyl-(or phenyl-) quinolines (14) were prepared through the reaction of 2- acetyl-5-nitro-1-methy...
Starting from 2-(2-pyridyl) imidazole a series of substituted imidazoles (2-5) were prepared. From the reaction of 2-(3-pyridyl) -4-(or 5) nitroimidazole (15) with dimethyl sulfate in alkaline medium 1-methyl-2-(3- pyridy1)-4-nitroimidazole (6,)w as prepared. Reaction of compound 15 with diazomethane gave I-methyl-2-(3-pyridy1)-5- nitroimidazol(e7 ) in addition to 6. The antibacterial and an...
