Substituted 2, 4- diphenyl quinolines were synthesized by a multicomponent domino reaction of anilines, aldehydes and terminal aryl alkynes. The synthetic pathway involves the formation of an imine, followed by the intermolecular addition of an alkyne to the imine. This intermediate immediately undergoes ring closure and oxidative aromatization. The reaction is catalyzed by natural kaolin, a st...

In present study we used five green plants for microwave assisted synthesis of Alumina nanoparticles from Aluminum nitrate. Structural characterization was studied using x-ray diffraction that showed semi- crystalline and possibly, amorphous structure. Fourier infrared spectroscopy was used to determine Al-O bond and functional groups responsible for synthesis of nanoparticles. FTIR confirmed e...

A facile synthesis of mercaptanacid-capped CdTe/CdSe (core/shell) type II quantum dots in aqueous solution by means of a microwave-assisted approach is reported. The results of X-ray diffraction and high-resolution transmission electron microscopy revealed that the as-prepared CdTe/CdSe quantum dots had a core/shell structure with high crystallinity. The core/shell quantum dots exhibit tunable ...

the genus haplophyllum, which belongs to the rutaceae family, includes 18 species in iran. in this study, after collecting plant material, botanical identification and suitable drying, the essential oils from aerial parts of haplophyllum robustum bge. were extracted by three different isolation techniques, conventional hydrodistillation (hd), microwave-assisted hydrodistillation (mahd) and solv...

the aluminum oxide materials are widely used in ceramics, refractories and abrasives due to their hardness, chemical inertness, high melting point, non-volatility and resistance to oxidation and corrosion. the paper describes work done on synthesis of α-alumina by using the simple, non-expensive solution combustion method using glycine as fuel.aluminum oxide (al2o3) nanoparticles were synthesiz...

A solution based economically low cost, eco-friendly, and energetically advantageous alternative route for the fabrication of ultrafine LiFe0.95Ti0.05PO4 (LFTP) LiFePO4 (LFP) polycrystalline materials by semi-wet combustion sol–gel synthesis is presented in this chapter. The energy dispersive X-ray (EDX) spectra LFP LFTP material were observed with high-resolution transmission electron microsco...

Curcumin is the natural bio-active component of turmeric (Curcuma longa L.) with known therapeutic properties; nevertheless, its biological applications are limited due to its poor bioavailability. To overcome this limitation, curcumin was conjugated with silica nanoparticles. Curcumin was separated from turmeric by microwave-assisted extraction and silica nanoparticles were developed from rice...
