	Abstract:Atomic layer deposition (ALD) technology is induced to encapsulate inverted indium-tin-oxide (ITO)-free polymer solar cells (IFSCs) with a structure of Al/TiOx /P3HT:PC61BM /PH1000. Al2O3 served as encapsulation layer is deposited by ALD on the light incident surface (PH1000 anode). The thickness of Al2O3 layer thus can be optimized through optical simulation to minimize light loss on IFSCs. With Al2O3 of 30 nm and active layer of 85 nm obtained from optical calculation, the ALD encapsulated IFSCs show much better device performance and higher stability than the glass-encapsulated IFSCs with active layer of 80 nm.

	3. Local Composition Model for the Phase Equilibrium, Phase Densities and Surface Tensions of Hydrocarbon-Hydrocarbon and Hydrocarbon-CO2 Mixtures
	ZHU Junyue,DUAN Yuanyuan,YANG Zhen

	Abstract:Phase equilibrium, phase densities and surface tensions of hydrcaorbon-hydrocarbon (HC-HC) and hydrocarbon-CO2 (HC-CO2) vapor-liquid system have great importance in separation, purification and dissolution processes. In this work, a local composition model was introduced into the volume translated Peng-Robinson(VTPR) equation of state(EOS) to calculate the phase equilibrium and phase densities. And then the local composition combined with VTPR EOS was used to predict the surface tensions based on the gradient theory. The results show that the introduction of the local composition model can achieve accurate calculation of phase equilibrium, phase densities and surface tensions for binary HC-HC and HC-CO2 mixtures.

	4. Au@SiO2 core/shell nanoparticles decorated TiO2 nanorod arrays for enhanced photoelectrochemical water splitting
	SHEN Shaohua,CHEN Jianan

	Show/Hide Abstract \| Cite this paper︱Full-text: PDF (0 B)

	Abstract:To improve the separation efficiency of photo-induced charge carries, Au@SiO2 nanoparticles with core-shell structure were loaded onto the surface of TiO2 nanorods grown on FTO substrate by a facile two-step process. The resulted Au@SiO2/TiO2 photoanodes were characterized by X-ray diffraction (XRD), Scanning electron microscopy (SEM), Transmission electron microscopy (TEM) as well as photoelectrochemical measurements. When compared to pristine TiO2 nanorod film, the Au@SiO2/TiO2 films showed remarkable enhancement in photoelectrochemical water splitting, with incident photon to current conversion efficiency (IPCE) increased from 31% to 37% at 380 nm and 0.8 V vs. SCE. This could be interpreted by the effect of metallic surface plasmon resonance of Au@SiO2 nanoparticles, which would generate an intense electromagnetic field with spatially non-homogenous distributed intensity. As a result, the charge carriers generated in the near surface region of TiO2 nanorods could be easily separated. This modification method based on the effect of metallic surface plasmon resonance for promoted charge carrier separation provides a promising way to develop semiconductor photoelectrodes with high solar water splitting performance.

	5. Enhanced electrochemical performances of CuCrO2-CNTs nanocomposites anodes by in-situ hydrothermal synthesis for lithium ion batteries

	Abstract:The CuCrO2-carbon nano-tubes (CNTs) nanocomposites synthesized by in-situ hydrothermal method exhibit excellent specific capacity retention and cyclic performances. Due to the poor conductivity and large volume variation of CuCrO2, its discharge capacity only remains 304 mAh g-1 (0.2 C) after 140 cycles. The electrochemical performances of CuCrO2 anodes are improved remarkably by adding 5-20 wt% CNTs. The CuCrO2-CNTS composite anodes maintain a specific capacity of 742 mAh g-1 after 60 cycles (0.2 C) when the CNTs proportion is over 10 wt%. Even at 1 C charge/discharge rates, they still exhibit high capacity retention of 530 mAh g-1 after 40 cycles. The SEM micrographs show that CNTs are dispersed well within the CuCrO2 matrix to form a 3D network. Such a network structure provides good electrical conductivity and restrains the volume variations during the cycling processes, which collaboratively improve the discharge specific capacity and cycling performance.

	Abstract:The VO2 nanorods were prepared with V2O5 by hydrothermal method. Polypyrrole was coated on the surface of VO2 through in-situ polymerization. The VO2 particles coated with polypyrrole were mixed with NH4H2(PO4)3 and Li2CO3 in ethyl alcohol according to the stoichiometry of Li3V2(PO4)3 to synthesize the cathode material Li3V2(PO4)3/C. Polypyrrole coated on the surface of VO2 nanorods was carbonized in the process of calcination to inhibit the growth of Li3V2(PO4)3 grains. A battery was assembled with Li3V2(PO4)3/C (cathode) and lithium metal (anode) to test the electrochemical performance of cathode material. The constant current charge/discharge cycling performance was measured in the potential range of 3.0-4.3 V. The discharge capacities were 130, 125, 123 and 115 mAh g-1 at the rates of 0.2, 1.0, 2.0 and 5.0 C, respectively. And the discharge specific capacity was 121 mAh g-1 after 600 cycles at 1.0 C, meaning the discharge specific capacity retention rate was as high as 96 %. The grain refinement enhances the electrochemical performance of Li3V2(PO4)3/C.

	7. Experimental Study of Complicated Phase Change Heat Transfer in Confined Space

	Abstract:The experimental results of complicated phase change heat transfer characteristics in confined space are presented. The working medium used is de-ionized water, the heating and cooling surfaces are polished copper. The confined space is a closed chamber that consists of a heating copper block whose top surface is used for boiling, a cooling copper block whose bottom surface is used for condensing and a circular wall made of stainless steel. The distance between the heating and cooling surfaces of the confined chamber is 26 mm, and the water layer thickness in the chamber is set at 10 mm, 12 mm, 14 mm and 16 mm, respectively. Experimental observation and results show that boiling and condensation processes are strongly inter-related and have significant influences over each other. As the water level increases, the boiling heat transfer coefficient increases at first and then decreases. Analysis of the standard deviations of the confined space pressure shows that as the heat flux increases, the pressure fluctuation increases first and then tends to maintain a constant. The experimental results also disclose that there exists an optimum water filling amount at which both the boiling and the condensation heat transfer coefficient acquire their maximum value.

	9. Carbon-supported Co-pyridine as non-platinum cathode catalyst for alkaline membrane fuel cells

	Abstract:In this work, carbon-supported pyridine-cobalt nanoparticles (CoPy/C) are synthesized using cobalt sulfate heptahydrate (CoSO4 7H2O) and pyridine (Py) as the Co and N precursors via a solid state reaction by heat-treatment in an inert atmosphere at 800oC. In particular, the ORR kinetics on these catalyst materials are evaluated using cyclic voltammetry (CV) and rotating disk electrode (RDE) in electrolytes of various KOH concentrations, ranging from 0.05 to 12.0 M, because ORR is more favourable in alkaline electrolytes than in acidic and neutral electrolytes. The Koutecky-Levich equation analysis indicates that oxygen can be reduced to OH- with high selectivity through a direct four-electron pathway mechanism in KOH concentrations in the range of 0.05 - 6.0 M. These catalysts exhibit the superior methanol tolerance to commercial 40%Pt/C catalyst, and the negative effect of higher concentration of KOH is much less for CoPy/C than for Pt/C, suggesting the promising utilization of CoPy/C catalysts as electrocatalysts for alkaline polymer electrolyte membrane fuel cells.

	Abstract:A special monocrystalline silicon solar cell provided by CSUN was studied through an indoor experimental platform based on a DLSK-SOL3 solar-simulator and module measurement system. The illumination density of light was modulated to simulate a low concentration condition (0.2sun?10sun) by varying the working voltage of the Xenon lamp and the distance between the test module and the Xenon lamp. The temperature of solar module is at the range of RT to 50℃。The temperature-dependence properties were obtained.
