La2Ce2O7 nano-powders with cubic fluorite structure have been firstly prepared by Molten Salts method. These nano-powders were prepared at relatively low temperatures(800°C and 900 °C) at different time, using La(NO3)3•6H2O and La(NO3)3•6H2O as raw materials, as well as K2SO4 (anhydrous) and Na2SO4 (anhydrous) as molt…
The polycrystalline V2O5 films as the anode in V2O5 /LiPON /LiCoO2 lithium microbattary were prepared by RF magnetron sputtering system. The V2O5 films’ crystal structures, surface morphologies and composition were characterized and analyzed by X-ray diffraction (XRD), scanning electron microscopy (SEM) and X-ray phot…
ZnO single-crystalline films were prepared by predepositing a homobuffer layer on Si (100) substrate in a pulsed laser deposition system. The effect of short-time rapid thermal annealing under N2 and O2 ambient on the optical property was systematically studied by photoluminescence measurements from 77K to room temper…
This research was aimed to study the electrospinning of natural rubber (NR)-acrylonitrile butadiene styrene (ABS) blend. The NR used in this research was compounded in a torque rheometor, with stearic acid, wingstay-L, dibenzothiazoledisulfide (MBTS), tetramethylthiuram disulfide (TMTD) and sulfur, respectively. The c…
The environmental and health hazards associated with chromium-containing solution have aroused wide public concern, so attempts have been made to find alternatives for metal finishing. In the present paper, inhibition effect of acridine on corrosion of hot dipped Zn and Zn-Al alloy coatings on steels in diluted hydroc…
Abstract Bias enhanced nucleation (BEN) is the crucial process step to generate epitaxially oriented diamond nuclei on various substrates comprising elemental semiconductors, carbides and non‐carbide forming metals. Numerous studies on Si and SiC have shown that the diamond growth immediately starts during the biasing…
Abstract In this work, we present a study about the homoepitaxial growth of phosphorus‐doped diamond on (100) substrates. The growth was performed by microwave plasma assisted chemical vapor deposition (MPCVD) adding an organic precursor for phosphorus (tertiarybutylphosphine: TBP) in the gaseous phase. We show that p…
Poly (vinyl pyrrolidone) (PVP)/magnesium acetate composite fibers were prepared by electrospinning technique via sol–gel process. Magnesium oxide (MgO) submicrometer fibers (solid) and tubes (hollow) with diameter in the range of 100–400 nm were successfully prepared by calcinations of PVP/magnesium acetate composite…
In this paper, the intercalation of methyl-red (MR) into Mg/Al (ratio=2:1) layered double hydroxide (LDH) was carried out using reconstruction method to obtain MRLDH nanocomposite material. Its chemical composition, crystal structure and appearance were characterized by XRD, FT-IR, TEM, TG-DTA and element analysis. It…
Abstract Single crystals of Pr 4 S 3 [AsS 3 ] 2 can be obtained through the reaction between the elements praseodymium, arsenic and sulfur using CsCl as fluxing agent in torch‐sealed evacuated silica ampoules. The starting materials were heated for ten days at 700 °C and then cooled down slowly to room temperature. Th…
Crystal structures of lactose permease from Escherichia coli (LacY) exhibit two six-helix bundles with 2-fold pseudosymmetry separated by a large hydrophilic cavity. The cavity is open only on the cytoplasmic side and contains the side chains important for both sugar and H(+) binding at the apex in the middle of the p…
In this study, the effect of addition Calcium carbonate (CaCO3) filler component on solid state thermal decomposition procedures of Polypropylene-Low Density Polyethylene (PP-LDPE; 90/10 wt%) blends involving different amounts (5, 10, 20 wt%) Calcium carbonate (CaCO3) was investigated using thermogravimetry in dynamic…
The electrical resistivity and positive temperature coefficient (PTC) behavior of carbon black (CB)-filled high density polyethylene (HDPE) /ethylene-vinyl acetate copolymer (EVA) composites were investigated. At any particular CB content, the composite with the HDPE/EVA weight ratio 9/1 showed the lowest resistivity…
Multiblock copolymers containing periodically spaced side-chain carboxyl groups were obtained by a two-step synthesis involving the preparation of ABA triblock prepolymers of lactic acid (A block) and ethylene glycol (B block) followed by chain extension to (ABA) n multiblock copolymers by reaction with pyromellitic d…
Abstract Single crystals of Sr M 2± x Ru 4 ∓ x O 11 with M = Fe, Co with maximum width of 2 mm and a thickness around 0.05 mm were grown from a chloride flux. Sample compositions were determined from refinements of X‐ray diffraction data and microprobe analysis. The hexagonal crystal structure (space group P 6 3 / mmc…
We report that pentacene can be used as a protection layer of graphene using synchrotron radiation-based photoemission spectroscopy. When pentacene was deposited on a single layer graphene, molecular states of pentacene were clearly observed, yet no change in the band structure of graphene could be identified. Unique…
We present the x-ray absorption spectra that show the Co valence state and the orbital character of the conduction band of delafossite ${\text{PdCoO}}_{2}$. The $\text{Co}\text{ }2p$ x-ray absorption spectra of ${\text{PdCoO}}_{2}$ and ${\text{PtCoO}}_{2}$ show that the Co ions have the trivalent low-spin configuratio…
A method has been recently proposed for determining the value of the surface tension of a solid in the absence of adsorption, gammaS0, using material properties determined from vapor adsorption experiments. If valid, the value obtained for gammaS0 must be independent of the vapor used. We apply the proposed method to…

Starch based wood adhesive prepared by in emulsion synthesis have green material, superior property, low cost. The effects of vario…
Thermochromic vanadium dioxide (VO2) exhibits a semi-conducting to metallic phase transition at about 68°C, involving strong variations in electrical and optical properties. A simple method was proposed to prepare VO2 thin films from easily gained V2O5 thin films. The detailed thermodynamic calculation was done and th…
