Abstract High-entropy TaNbSiZrCr carbide coatings were deposited on WC substrates by radio-frequency unbalanced magnetron sputtering with C2H2 flow rates ranging from 0 to 23 sccm. The microstructure, mechanical properties, tribological properties and anti-corrosion resistance of the coatings were analyzed in both an as-sputtered condition and an annealed condition. The anti-glass sticking performance of the coatings was additionally investigated by annealing the coatings at 750 °C for 1 h on BK...

Abstract Carbon/graphite nanocomposite (CGn) film had been employed as cathode for hole transport layer (HTL) free, mesoscopic, heterojunction perovskite solar cells (PSCs). Hydrophobic CGn film shows impressive charge transport characteristics that makes it promising candidate for cathode in HTL free PSCs. The electrochemical impedance spectroscopy measurements realised the significant charge transport characteristics can get for (10 μm–14 μm) thin film. On the other hand, the hydrophobic (Cont...

Abstract Amorphous Ru-Pi nanoclusters deposited on PEDOT modified carbon fibre paper electrode have been investigated as a potential oxygen evolution electrocatalyst. CFP/PEDOT/Ru-Pi electrode was prepared by electrodeposition of Ru-Pi nanoclusters on PEDOT decorated CFP using cyclic voltammetry (CV). Field emission scanning electron microscopy with energy-dispersive X-ray spectroscopy (FESEM-EDS), attenuated total reflection with Fourier-transform infrared spectroscopy (ATR-FTIR) and X-ray diff...

Abstract Silver nanowires (AgNWs) have attracted growing interest because of their wide range of applications in modern nano electronic appliances. During polyol method, the presence of cations and anions in the reaction solution has influence on the final morphology of AgNWs. Here we report a feasible way to prepare AgNWs by polyol method. Copper bromide (CuBr2) salt was used to provide anions and cations in the reaction solution. The anions (Br−) helps in reducing the amount of free Ag+ by for...

Abstract High boron Fe-based alloys, possessing superior wear-resistant performance, have always been restricted to be applied in impacting conditions by the poor toughness. In the present work, Fe-3.0B-0.3C alloy has been toughened by introducing Cr element. The evolutions of the solidification process, microstructure and the mechanical properties have been systematically investigated by means of the scanning electron microscope (SEM), transmission electron microscope (TEM), differential scanni...

Abstract Dysprosium-doped Ruddlesden−Popper calcium manganates with compositions of Ca2-xDyxMnO4 are potential candidates for high temperature thermoelectric applications. The effect of dysprosium doping on the crystal structure of Ca2-xDyxMnO4 at room temperature and its thermal behavior between RT and 800 °C were investigated in the range 0

Abstract Low-cost biomass-derived carbon nanomaterials hold great promise as catalysts for the oxygen reduction reaction. Here, we have successfully prepared an N, S co-doped metal-free porous carbon catalyst through the synchronous pore-forming/doping technology. The thiourea plays dual roles as a porogen and dopant in the synthesis process. After coupling with thiourea, the successful doping of N and S elements in NSMP-I increase their defects, specific surface area, and pyridine nitrogen grou...

Abstract The volume shrinkage and conversion rate are important factors determining the defect generation and accuracy control of green parts in ceramic stereolithography. In this study, a specific laser reflection method with coverslips and real-time Fourier-transform infrared (RT-FTIR) spectroscopy were used to determine the effects of the double-bond concentration, monomer ratio, photoinitiator, and incident light intensity on the real-time volume shrinkage and conversion rate. A slurry with ...

Abstract The T-shaped groove surface with groove width of 0.3 to 1.2 mm and groove depth of 0.6 to 1.5 mm is prepared on the copper surface by using electric spark wire cutting technology, Set up a set of wall temperature measurement, bubble visualization and steady flow heating test bench. Experimental observations of boiling heat transfer of deionized water on different heat transfer surfaces are achieved. The boiling curves of T-shaped surface such as superheat, heat flux and heat transfer co...
