We explore a simple and eco-friendly approach for preparing CZTS powders and a screen-printing process for Cu2ZnSn(S,Se)4 (CZTSSe) counter electrodes (CEs) in dye-sensitized solar cells (DSCs). Cu2ZnSnS4 (CZTS) nanoparticles have been synthesized via a hydrazine-free solvothermal approach without the assistance of organic ligands. CZTS has been prepared by directly drop-casting the CZTS ink on the cleaned FTO glass, while CZTSSe CEs have been fabricated by screen-printing CZTS pastes, followed by post selenization using Se vapor obtained from elemental Se pellets. The crystal structure, composition and morphology of the as-deposited CZTS nanoparticles and CZTSSe electrodes are characterized by X-ray diffractometer, energy dispersive spectrometer, field emission scanning electron microscopy and transmission electron microscopy. The electrochemical properties of CZTS, CZTSSe and Pt CE based DSCs are examined and analyzed by electrochemical impedance spectroscopy. The prepared CZTS and CZTSSe CEs exhibit a cellular structure with high porosity. DSCs fabricated with CZTSSe CEs achieve a power conversion efficiency of 5.75% under AM 1.5 G illumination with an intensity of 100 mW/cm2, which is higher than that (3.22%) of the cell using the CZTS CE. The results demonstrate that the CZTSSe CE possesses good electrocatalytic activity for the reduction of charge carriers in electrolyte. The comprehensive CZTSSe CE process is cheap and scalable. It can make large-scale electro-catalytic film fabrication cost competitive for both energy harvesting and storage applications.

The shear behavior of prestressed self-compacting concrete (SCC) beams has been investigated in this study. The effect of compressive strength of SCC on the shear strength has been taken into account in test program. Based on the experimental data, the failure mechanism of the prestressed SCC beams was discussed and the shear transfer mechanism of the RC beam after the flexure-shear cracking was also analyzed.
In the present invention, interactive data, audio data and video data are encoded, packaged and multiplexed into interactive television programs; a receiving terminal receives the interactive television programs, unpackages and decodes the interactive television programs and transmits unpackaged interactive data by using a near field communications module; and an operation terminal receives the unpackaged interactive data by using its near field communications module, and parses corresponding participation information in the current television programs to interact with the current television program content.
One or more pins may be modally assigned to either the command/address (C/A) or data (DQ) blocks of a uniform-package, multi-modal PHY (physical signaling interface) of a memory controller, thus enabling those pins to be used as C/A pins when the PHY is connected to some memory types, and as DQ pins when the PHY is connected to other memory types.

In the coal mine of Huaibei Mining Area, based on the character of thick dirt band in the coal seams and the influences to top coal caving, the physical and mechanical properties of dirt band were analyzed. In order to improve the recovery rate of top coal, the failure mechanism of dirt band was analyzed through the cantilever beam model, and the sensitivity analysis to the length of dirt band overhang was done in the conditions of different mining height and dirt band thickness. The results show that, the average water absorption of dirt band samples is 3.5%, and the soften coefficient is 0.71, which presents that the dirt band have large softening property and poor engineering geological property. When the thickness of dirt band was more than 3.5 m, the top coal could not be caved smoothly. However, the bigger underground pressure would be helpful to the broken of dirt band and top coal seams, and the recovery rate of top coal was improved.
