We report a simple, green and cost-effective approach to synthesize high-quality reduced graphene oxide/chitosan composites for determining flubendiamide. Graphene oxide was obtained by electrochemical exfoliation of pencil using DC supply system.

The green sulfur bacterium Chlorobium tepidum produces chlorobactene as its primary carotenoid. Small amounts of chlorobactene are hydroxylated by the enzyme CrtC and then glucosylated and acylated to produce chlorobactene glucoside laurate. The genes encoding the enzymes responsible for these modifications of chlorobactene, CT1987, and CT0967, have been identified by comparative genomics, and ...

Culture conditions are described under which Cyanophora paradoxa grows with a generation time of less than two days. The organism is an obligate photoautotrophic flagellate unable to degrade exogenous carbohydrates via respiration. It does not synthesize nitrogenase but can form a hydrogenase with similar properties as in blue-green algae. The photosynthetic 0 2-evolution pro­ ceeds with essent...

background: to develop a new green approach for biosynthesis of silver nanoparticles, myconanotechnology has been represented as a novel field of study in nanotechnology. in this study, we have reported the extracellular synthesis of highly stable silver nanoparticles using three species of dermatophytes: trichophyton rubrum, trichophyton mentagrophytes and microsporum canis. methods: clinical ...

Due to increasingly noticeable environmental impacts of business activities and consequently rising demands for environmental information by organizational stakeholders, reliable sustainability reporting (SR) is ever more important for firms. As the task of detailed sustainability reporting is complex and involves gathering and processing of a considerable amount of data, green information syst...

A simple, green, and efficient approach was used to synthesize 3,4-dihydropyrimidines derivatives. We showed that the application of the planetary ball milling method with a ball-to-reagent weight ratio of 8 for the Biginelli reaction provides 3,4-dihydropyrimidines derivatives with excellent yields (>98%) in a short reaction time from the one-pot, three-component condensation of aldehydes, eth...
