Abstract
  The microwave assisted preparation and characterization of chitosan-surfactant modified NaMMT clay composite material is discussed, followed by its interesting application to detoxify heavy metal chromium. Cr(VI) could be effectively adsorbed in a weakly acidic medium (pH 5) from a large sample volume. ...  Read More

Facile preparation of nanoporous platinum and its high electrocatalytic performances

Jiagang Hou; Haoran Geng; Caixia Xu; Xiaolei Mu; Jinshui Yao

Volume 2, Issue 6 , December 2011, Pages 392-396

https://doi.org/10.5185/amlett.2011.2225

Abstract
  Nanoporous platinum was fabricated by a simple dealloying method. Electron microscope characterizations show that selectively etching Al from PtAl alloy precursors in alkali or acid solution can both easily prepare three-dimensional bicontinuous network nanostructures of Pt. The resulted nanostructure ...  Read More

Morphology and electrical conductivity of self- doping polyanilines synthesized via self- assembly process

S.R. Kargirwar; S.R. Thakare; M.D. Choudhary; S.B. Kondawar; S.R. Dhakate

Volume 2, Issue 6 , December 2011, Pages 397-401

https://doi.org/10.5185/amlett.2011.4245

Abstract
  Copolymerization of self doping monomer aniline and oxalic acid (OA)/ acetic acid (AA) in different molar ratio via the self-assembly process were conducted to prepare self-doping polyanilines (SD-PANIs). In this polymerization process, AA or OA plays the roles of surfactant and dopant for the self-doping ...  Read More

Microstructure, phase formations and optical bands in nanostructured alumina

Jitendra Gangwar; Kajal Kumar Dey; Surya Kant Tripathi; Avanish Kumar Srivastava

Volume 2, Issue 6 , December 2011, Pages 402-408

https://doi.org/10.5185/amlett.2011.3233

Abstract
  We report the synthesis of nano-scaled alumina of varied dimensions through a novel optimized processing of aluminum nitrate. The X-ray diffractometry confirmed the formation of X- and γ- phases of alumina particles in the nano region, depending on the annealing conditions during processing. Subsequently, ...  Read More

Liquid-Phase Synthesis of Nickel Nanoparticles stabilized by PVP and study of their structural and magnetic properties
