Binary ZnSe thin films were prepared by spin-coating and chemical co-reduction, the effects of reaction conditions on thin films were investigated. The phases of obtained samples were characterized by X-ray diffraction (XRD). The size and morphology of the products were observed by scanning electron...

CuGaS2 as a ternary semiconductor with chalcopyrite structure has a direct bang-gap of 2.43 eV at room temperature corresponding to the wavelength of 0.51 ?m, it is a promising absorption layer for photovoltaic material. In this work, convergence of the plane wave cut-off energy and the K-mesh were carried...

Cu2ZnSnSe4 thin films were prepared at 160~200 oC by spin-coating and chemical co-reduction, the effects of reaction temperature, time and substrates on thin films were investigated. Experimental results show that, the temperature, reaction time and process are the main factors that affect crystal phase...

Perovskite-type cube structure LaMnO3 nanofibers of approximately 50~100 nm in diameter were synthesized via Sol-Gel processing and electrospinning technology after calcined at 900? by using polyvinypyrrolidone (10 wt %PVP) as complexing agents. The nanofibers were characterized by experiment technology....

Research the pyrolysis kinetics of eucalyptus and the absorption band and characteristic peaks of volatile pruducts under the heating rate 10?•min-1, 30?•min-1, 60?•min-1respectively. The experimental results show that eucalyptus pyrolysis process can be divided into 3 stages: moisture volatilizes stage,...

New ultrasonic-assisted brazing technology was adopted to weld mini butt joint by SnBi composite solder with 1.5wt% Al2O3 content and 0.5mm, 0.8mm and 1mm three kinds of copper substrate distance. The mechanical properties of the mini butt joint were characterized by means of the micro hardness tester...

The AB5-type hydrogen storage alloys La0.7Ni2.5Co0.9-xMn0.1Alx were prepared by magnetic induction melting. The structure and the electrochemical properties of alloys were also investigated using X-ray powder diffraction technique and various electrochemical measurements. All the alloys are mainly composed...

A first-principle study on the conductive path formation induced by the aggregated O ions in the defected titanium dioxide (Ti12O29) is reported. The result illustrates that the O interstitials induce the aggregation of the O-ions. Thus, the formation of the conductive path is attributed to the continuous...

The drawing mold of Miniature Inner Grooved Copper Tubes (MIGCT) is made of WC-Co hard alloy, TiAlN coating is deposited on the substrate of WC-Co hard alloy. Inspections on binding force and hardness show that TiAlN coating is provided with fine surface finish and can meet the requirement of industrial...

Scratched alkyd varnish coating (AVC) with isophorone diisocyanate (IPDI) microcapsules as functional additives display self-healing properties. Here, we investigated the mechanism of the self-healing process using a water trigger in seawater. FT-IR spectra of the self-healing products in the scratched...

The purpose of this paper is to examine whether low pressure cold spray can deposit high quality Al-PTFE Composites Coating or not. Different Polytetrafluoroethylene (PTFE) content Al-PTFE composite powders were used to deposit composites coating with low pressure cold spraying methods under the parameter...

In this paper, boron doped diamond (BDD) thin flms have been deposited on Ti-based substrates with or without a Ta intermediate layer by microwave plasma chemical vapour deposition (MWCVD). Raman spectroscopy and scanning electron microscopy (SEM) examinations demonstrate that the electrode has well-defined...

The RuO2- IrO2-SnO2/Ti anodes were prepared by the sol–gel procedure. SEM, EDX and XRD showed that the rutile structured RuO2–IrO2–SnO2 solid solution was formed after pyrolysis, the solid solution structure and active components were almost disappeared after the deactivation of the anodes. Electrochemical...
