A simple and cost effective hydrothermal method has been done for the synthesis of MoS2 and MoS2/rGO nanocomposites. The prepared MoS2/rGO composite was characterized by XRD, FESEM and TEM which revealed the formation and as well as the morphological scenario of MoS2/rGO nanocomposite. Pure MoS2 and MoS2/rGO nanocompo…
Nanotechnology is a fast growing field and nanoparticles are viewed as fundamental building block of nanotechnology. The most important and distinct property of nanoparticles is that they exhibit larger surface area to volume ratio (Albrecht et al., 2006). The most effectively studied nanoparticles today are those mad…
click reactions, ethylene glycol moieties containing two different terminal groups to discrete areas towards the exterior of a PSi rugate filter. The patterning of biological species to the functionalized surface was demonstrated through the conjugation of fluorescein isothiocyanate labelled bovine serum albumin (FITC…
Temperature of the cutting tool is one of the most important factor affecting the tool wear in wood processing, because the basic properties of the material from which a tool is made, such as hardness, toughness and chemical stability, degrade with increasing tool's temperature. The effect of different wear mechanisms…
Under ambient temperature and atmospheric pressure conditions, phenol could be completely oxidized to CO <sub>2</sub> with catalyst [C <sub>16</sub> H <sub>33</sub> (CH <sub>3</sub> ) <sub>3</sub> N] <sub>4</sub> H <sub>2</sub> SiV <sub>2</sub> W <sub>10</sub> O <sub>40</sub> .
In this article, we have synthesized a polymer containing regulated azobenzene groups by one-pot multi-component polymerization (MCP) based on Passerini reaction, and investigated its self-assembly behavior and photo-induced deformation properties. We found that this molecule can form spherical structures with sizes r…
The effect of transition metal fluorides on the decomposition of NaBH4 has been investigated for NaBH4 ball milled with TiF3, MnF3 or FeF3. The compounds were examined by thermal programmed desorption with residual gas analysis, thermo gravimetric analysis and volumetric measurements using a Sieverts-type apparatus. T…
A new technology based on bio-templating approach was proposed in this paper. Egg-shell membrane (ESM) has been employed as a natural biotemplate. Fibrous oxide ceramics was prepared by wet impregnation of biological template with water solution of cerium nitrate. The template was derived from membranes of fresh chick…
A systematic evaluation of the factors governing the measured thermal and mechanical property reinforcement in crosslinked polyethylene nanocomposites is presented.
To obtain a columnar structure with nucleophilic channels embedded in the column centres, we synthesized a series of new crown ether derivatives (compounds 1, 2, and 3) which are composed of a core of dibenzo-24-crown-8 symmetrically surrounded by four identical substituents. Experimental results indicate that compoun…
Thermoresponsive glycopolymers have been prepared by a free radical polymerisation process, and subsequently processed into blended fibers with poly- <sc>l</sc> -lactide- <italic>co</italic> -ε-caprolactone (PLCL) using electrospinning.
High conductivity and the absence of ferromagnetism in pristine graphene fail to satisfy primary criteria for possible technological application in spintronics. Opening of the bandgap in graphene is primarily desirable for such applications. We report a simplified and novel approach of controlled grafting of a magneti…

The charge transport of a π-stacked polymer was manipulated by silicon incorporation to realize molecular nanofuse devices in a silicon-stimulated filament mechanism.
The redox reactions of highly epitaxial LaBaCo <sub>2</sub> O <sub>5+δ</sub> (LBCO) thin films exposed to the switching flow of reducing (H <sub>2</sub> ) and oxidizing (O <sub>2</sub> ) gases were examined at various temperatures between 260 and 700 °C. Their electrical resistance was measured using a precise ac brid…
This study presents a characterization of the degree and mechanism of corrosion inhibition of Zn by vanadate inhibitors. A combination of open circuit potential measurements, anodic and cathodic polarization, and Raman spectroscopy were used to compare corrosion inhibition of Zn exposed to or pre-treated with a dilute…
A number of known catalysts, which have been proven to be very effective for several hydrogen species, were studied in order to determine their effects on the hydrogen ab/desorption properties of KSiH3. Among all the catalysts used in this work, mesoporous Nb2O5 is found to be quite effective, with a reduction in acti…
Mercury thioarsenate glasses (HgS) <sub>x</sub> (As <sub>2</sub> S <sub>3</sub> ) <sub>1−x</sub> , 0.0 ≤ <italic>x</italic> ≤ 0.5, form a hybrid (HgS <sub>2/2</sub> ) <sub>n</sub> chain/AsS <sub>3/2</sub> pyramidal network, highly unusual for metal chalcogenide glasses. This network is evidenced by Raman spectroscopy…
We have studied the interaction of hydrogen with V-Mo and V-Mo-Ti alloys. Hydrogen absorption and desorption isotherms have been measured, the stability ranges of the forming hydride phases have been determined, and the Δ H and Δ S of the reactions involved have been calculated. X-ray diffraction results indicate the…
Photo-induced molecular motion in a liquid crystal polymer film including azobenzene was studied by the heterodyne transient grating method. The film was confined in a liquid crystal cell, where it is a photomobile film under free-standing conditions. By observation of the refractive index change induced by a laser pu…
