The vanadium-based catalyst, acts as a homogeneous catalyst for the selective oxidation of various kinds of sulfides with 30% aqueous H2O2. Vanadium-based catalyst was successfully used as the oxygen source for the oxidation of sulfides to sulfoxides for the first time. The sulfoxides were obtained in a good way to high yields without any detectable over-oxidation to sulfones under normal condi...

A versatile and green synthetic protocol has been developed for synthesis of substituted quinazolinone spiroquinazolinone heterocycles effectively via a combined surfactant mediated system. The use Surfactant, water as reaction medium, room temperature, high yield ease purification made the process very effective ecofriendly in nature. To demonstrate wide scope Isatoic anhydride Isatin used rea...

This paper presents an Effect of Fly Ash on Properties of Concrete. In the present study. Use of fly ash in concrete imparts several environmental benefits and thus it is ecofriendly. It saves the cement requirement for the same strength thus saving of raw materials such as limestone, coal etc required for manufacture of cement. Fly ash is pozzolanic material & it improving the properties of co...

Diclofenac Sodium, a Non-steroidal anti-Inflammatory drug (NSAID) was banned for veterinary use in Pakistan, India and Nepal in 2005-06 due to its relay toxicity associated with catastrophic decline in the populations of vulture in South Asia. The main aim of the present research was to study pharmacokinetics of meloxicam in goats under local conditions. Meloxicam is another NSAID, reported as ...

the fe-mcm-22 zeolite was found to be an efficient solid heterogeneous catalyst for synthesis of dihydropyrano [2,3-c] pyrazoles via one pot four component reaction of ethyl acetoacetate, hydrazine hydrate, aromatic aldehyde and malononitrile in aqueous alcohol. the catalyst was synthesized by hydrothermal method under autogenous pressure and modified by fe (iii) ion exchange. the prepared cata...

An extremely efficient catalytic protocol for the synthesis of a series of pyranopyrazole derivatives developed in a one-pot four-component approach in the presence of ZnO nanoparticles as heterogeneous catalyst using water as a green solvent is reported. Greenness of the process is well instituted as water is exploited both as reaction media and medium for synthesis of catalyst. The ZnO nanopa...

The development of easier, cheaper, and more ecofriendly synthetic methods for mesoporous materials remains a challenging topic to commercialize them, and the transformation of waste glycerol, as a biodiesel byproduct, into something useful and salable is one of the pending issues to be resolved. Here we first report that mesoporous silica (KIE-6) and carbon (KIE-7) can be simultaneously synthe...

silver nanoparticles (agnps) are amongst the most investigated materials in nanotechnology in view of their unique physio-chemical features and applications in restorative science. their progressive usages in different fields of science besides some predominant restrictions with conventional methods for their synthesis have demanded analysts to discover green courses for their creation. biologi...
