Postsynthetic modification of magnetic nano ferrites (Fe3O4) has been accomplished by anchoring glutathione and dopamine on the surface. The Cu nano particles immobilized over these surfaces were investigated for the coupling and cyclo addition reactions. The Fe3O4-DOPA-Cu (nano-FeDOPACu) catalyst showed activity for C-S coupling reactions whereas the Fe3O4-Glut-Cu (nano-FGTCu) catalyst was active for cyclo ad Read More

The size controlled 2D hexagonal structured Co3O4 with exposure of {111} plane was fabricated, and the catalytic properties for photooxidation of organics using as-prepared samples were investigated. 2D hexagonal structured Co3O4 with the size of 3 μm displays the higher photocatalytic activity than 200 nm size for the photooxidation of IPA and cyclohexanol, both of which are higher than bulk Co3O4 suggesting that mor Read More

Short-term microwave irradiation was effectively used to devulcanize scrap ground tire rubber (GTR) particles. Microwave devulcanization was a short-time procedure, i.e. 1 min, 2 min and 4 min, during which, the GTR particles were exposed to continuous irradiation in order to cleave the cross-linked mono/di/poly sulfidic bonds (S-S, C-S) among their molecules to obtain the natural rubberlike ingredient. After that, polypyrr Read More

In comparison with the development of new materials with strong basicity, less attention is paid to the improvement of water resistance of solid bases. In the present study, Ca(NO3)2 and γ-Al2O3 was employed as base precursor and support, respectively, producing the materials denoted as CaNA. The results show that calcium ions can insert into the vacancies on the surface of γ-Al2O3 thus generating a strong guest-host int Read More

The rapid growth of science and technology in energy and environmental fields has enlightened the substantial importance of the conducting polymer and metal composite materials engineered at nano-scale. This is particularly manifested in the design and synthesis of novel sensor materials to achieve the desired morphology and property. Here, a brief review is presented about the recent works and advances on ta Read More

Continuous flow processes play a significant role in the process intensification of organic transformations, as is evident from the multitude of flow reactors that have been developed for various specific needs. These flow processes are deemed more sustainable due to the advantages associated with their use which include improved safety, enhanced efficiency, increased atom-economy and conversion, and ease of ha Read More

Pyrrole is one of the main five membered heterocyclic systems reported for its various chemotherapeutic activities. Subsequently, pyrroles have been highlighted as the important biologically active scaffolds. This review focuses on the synthesis, reactions and pharmacological activity associated with pyrroles, and its derivatives. Microwave-assisted reactions are also covered to understand green chemistry aspects of p Read More

In recent years, there has been a considerable interest in developing sustainable chemistries utilizing green chemistry principles. Since the first published report in 1986 by Gedye and Giguere on microwave assisted synthesis in household microwave ovens, the use of microwaves as an alternate non-conventional energy source in organic synthesis has been extensively explored. Microwave irradiation has been successful Read More

Synthesis of triazole based unnatural amino acids, triazole bis-amino acids and β-amino triazole has been described via stereo and regio-selective one-pot multi-component reaction of sulfamidates, sodium azide, and alkynes under MW irradiation conditions. The developed method is applicable to a broad substrate scope and has significant potential for the synthesis of triazole modified unnatural amino acids.

A simple, solvent free, microwave assisted alkylation of amines with alcohols catalyzed by manganese oxide impregnated γ-Fe2O3 is reported

Many organic pesticides that were banned a few decades ago, as well as those that are currently in use in many parts of the world, pose some serious threat to human life and the ecosystem because of their persistent and bioaccumulative nature. In the recent years advanced oxidation technology has been widely employed in water treatment for elimination of resistant organics. An actively researched green chemistry Read More

1-(2-Furanyl)-2-(3-indolyl)ethanone (FIE, 4) is a potent ligand of the human aryl hydrocarbon receptor (AhR), the so-called dioxin receptor, and the estrogen receptors (ERs), with high activities in transactivation assays. Direct synthesis approaches towards 4 have been hampered by the high oxidative instability of both the indole moiety and the furan part. A biomemetic synthetic pathway was devised that provides the compo Read More

Polyols or sugar alcohols are sugar-derived metabolites. The origin, metabolic fate and functions of most of them are not clear. The monitoring of polyols can be helpful in the diagnosis and treatment of diseases, especially those of unknown etiology. The main aim of the study was to develop and demonstrate the efficiency, reliability, sensitivity of the gas chromatography - electron capture detection method for the quantificati Read More
