Microwave-Assisted Synthesis, Microstructure, and Physical Properties of Rare-Earth Chromites

21-Dec-2012 | Jesús Prado-Gonjal; Rainer Schmidt; Juan-José Romero; David Ávila; Ulises Amador; Emilio Morán, Inorganic Chemistry, 2012

The full rare-earth (RE) chromites series (RE)CrO3 with an orthorhombic distorted (Pnma) perovskite structure and the isostructural compound YCrO3 can be synthesized through a simple microwave-assisted technique, yielding high-quality materials. Magnetization measurements evidence that the Néel ...

Improved structural and catalytic attributes of Ba2Co2Fe12-2x(Zr,Ni)xO22 materials synthesized by sol-gel and microwave heating methods

12-Sep-2012 | Barkat Ul-ain; Safeer Ahmed; Yanqiang Huang; Ai-Qin Wang; Tao Zhang, Journal of Materials Chemistry, 2012

Nominal composition of Zr-Ni co-doped Ba2Co2Fe12-2x(Zr,Ni)xO22 (x = 0.2-1.0) Y-type hexaferrites were synthesized by conventional Sol-gel and novel microwave heating method. Structural analysis were carried out by TGA, SEM, XRD, O2-TPD and BET surface area. Microwave synthesized samples revealed ...

IJMS, Vol. 13, Pages 6730-6746: Rapid Synthesis and Antiviral Activity of (Quinazolin-4-Ylamino)Methyl-Phosphonates Through Microwave Irradiation

01-Jun-2012 | Luo, Hui ; Hu, Deyu ; Wu, Jian ; He, Ming ; Jin, Linhong ; Yang, Song ; Song, Baoan, International Journal of Molecular Sciences, 2012

This study describes the simple synthesis of new (quinazolin-4-ylamino) methylphosphonates via microwave irradiation. Substituted-2-aminobenzonitrile reacted with 1,1-dimethoxy-N,N-dimethylmethanamine at a reflux condition to obtain N'-(substituted-2-cyanophenyl)-N,N-dimethylformamidine (1). The ...

Proton-conducting membrane preparation based on SiO2-riveted phosphotungstic acid and poly (2,5-benzimidazole) via direct casting method and its durability

28-Feb-2012 | Suwen Wang, Feilong Dong, Zhongfang Li, Journal of Materials Science, 2012

SiO2-riveted phosphotungstic acid (T–PWA–SiO2) was synthesized using the sol–gel method and thermally treated in a microwave synthesizer. The dissolving-detaching experiment shows that PWA in T–PWA–SiO2 exhibits better fastness than in the sample without thermal treatment (PWA–SiO2). The ...

Performance of microwave synthesized dual solvent dope solution and lithium bromide additives on poly(ethersulfone) membranes

27-Jun-2011 | Ahmed Iqbal; I. Ani; Rizwan Rajput, Journal of Chemical Technology & Biotechnology, 2011

Abstract BACKGROUND: Generally the fabrication of polymeric membranes is a complicated and expensive process since it involves several steps. The preliminary preparation steps involve polymer drying and dissolution and is very time consuming and expensive. Currently, conventional electrothermal ...

Ordered mesoporous carbon with tunable, unusually large pore size and well-controlled particle morphology

11-Apr-2011 | Lung-Ching Sang; Ajayan Vinu; Marc-Olivier Coppens, Journal of Materials Chemistry, 2011

A method is proposed to synthesize well-ordered mesoporous carbon with a remarkably wide pore diameter using microwave-synthesized mesoporous silica, MWSBA-15, as the template. The pore size of the carbon is controlled by tuning the pore size of MWSBA-15, which is accomplished by varying the ...
