Frontiers In Bio-nanocomposites

Ashutosh Tiwari

Volume 2, Issue 6 , December 2011, Pages 377-377


  In today’s world, bio- nanocomposites are becoming increasingly prevalent owing to the extraordinary properties that they possess. Scientists learn to select suitable matrix (e.g. aliphatic polyesters, polypeptides and proteins, polysaccharides, and polynucleic acids) and fillers (e.g. nanotubes, ...  Read More

Green, formaldehyde-free, foams for thermal insulation

Maria C. Basso; Xinjun Li; Vanessa Fierro; Antonio Pizzi; Samuele Giovando; Alain Celzard

Volume 2, Issue 6 , December 2011, Pages 378-382


  New, green and cheap rigid foams presenting outstanding performances for thermal insulation are described. Such ultra-lightweight cellular materials are mainly based on renewable chemicals: tannin and furfuryl alcohol, are very easy to produce and have thermal conductivity as low as 38 mW/m/K. Compared ...  Read More

Microwave assisted preparation and characterization of biopolymer-clay composite material and its application for chromium detoxification from industrial effluent

A. Santhana Krishna Kumar; S. Kalidhasan; Vidya Rajesh; N. Rajesh

Volume 2, Issue 6 , December 2011, Pages 383-391


  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


  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


  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


  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

Mandeep Singh; Manish Kumar; Frantisek Stipanek; Pavel Ulbrich; Pavel Svoboda; Eva Santava; M.L. Singla

Volume 2, Issue 6 , December 2011, Pages 409-414


  We have synthesized nickel nanoparticles using nickel chloride as a precursor in ethanol using PVP (Poly Vinyl Pyrrolidone) as a surfactant and hydrazine hydrate as reducing agent at 60 °C in a facile manner. The structural analysis showed that particles are face-centered cubic and monodisperse within ...  Read More

Preparation and characterization of a photochromic hydrogel

Chen Mo; Lin Lin; Li Xiaoqiang

Volume 2, Issue 6 , December 2011, Pages 415-418


  A new type of photochromic hydrogel, spiropyran (SP)-Polyvinylpyrrolidone (PVP)-poly (N-isopropyl acrylamide) (PNIPAM) hydrogel with functionalized SP chemically incorporated, was synthesized. The molecular structure of synthesized products was given by nuclear magnetic resonance (NMR) spectra and infrared ...  Read More

  The AC impedance and conductivity properties of Ba0.8Sr0.2TiO3 ceramics in a wide frequency range at different temperatures have been studied. The compound was prepared by a high-temperature solid-state reaction technique. A preliminary structural analysis of the compound by X-ray diffraction technique ...  Read More

Simulation study of influence of Al, Si and B on the growth of TiC

Haimin Ding; Kaiyu Chu; Jinfeng Wang

Volume 2, Issue 6 , December 2011, Pages 425-428


  The influence of Al, Si and B on the growth of TiC is studied in this article. It is found that the adsorption of Al is more favorable on TiC {111} than that on {001}. Therefore, under the influence of it, the growth rate of {111} will be accelerated and result in the decreasing of the relative growth ...  Read More
