Preparation of nanomaterials with various morphologies and exploiting their novel physical properties are vital importance in nanoscientific field. Similarly to the III-N compound semiconductors, Si3N4 nanostructures also could be potentially used for making optoelectronic devices. In this paper, we report on an improved Fe-catalyzed chemical vapour deposition method synthesizing ultra-long α-Si3N4 nanobelts along a few nanowires nanobranches carbon felt substrate. The grew via combined...
The formation of lithium dendrites is recognized as the worst problem for metal batteries.
Sodium is one of the most promising anode candidates for beyond-lithium-ion batteries. The development Na metal batteries with a high energy density, safety, and low cost desirable to meet requirements both portable stationary electrical storage. However, several problems caused by unstable unsafe liquid electrolyte severely hinder their practical applications. Herein, we report facile but effective methodology construct an in situ polymer Na-rich artificial solid-electrolyte interface (SEI)...
Abstract Due to the abundant availability of Na resources, batteries garner significant attention. Anode‐free batteries, devoid active negative materials, are deemed promising candidates for next generation high‐energy‐density batteries. The cyclic stability anode‐free primarily hinges on limited supplied by cathode, and design anode substrate plays a pivotal role. In this study, cost‐effective aluminum–tin eutectic alloy is developed using straightforward melting process. alloy, tin element...
Calcium hexaluminate (CA6) was incorporated into the matrix of magnesio aluminate spinel-alumina (MA-A) via infiltration a porous preform fabricated from α-Al2O3 and MgO powders with saturated calcium acetate solution subsequent firing, forming CA6/(MA-A) functionally composites graded fracture toughness. Actually, partially perpendicularly immersed (1/4 its length) in solution. Owing to capillary action, absorbed different absorption distance led concentration height direction preform. The...
Sodium metal batteries have attracted extensive attention because of the high availability and energy density Na; however, practical application these is significantly plagued by dendritic growth. Aluminum has a unique advantage as current collector for sodium anodes its low cost. However, problems with dense aluminum oxide mean in seldom been studied. In this study, foam was fluorinated facile method compounded at temperatures to prepare sodiophilic foam@sodium electrode (NaHFAl). Because...
Porous calcium hexa‐aluminate ( CA 6 ) ceramics were in‐situ synthesized by heated CaCO 3 and α‐ Al 2 O in a NaCl ‐based salt at 1400°C for h, then characterized X ‐ray diffraction XRD ), scanning electron microscopy, SEM mercury porosimetry. The size morphology of the crystals pores gradually changed with increase addition raw material, indicating that molten not only provided liquid environment synthesis , but also generated considerable pores.

Abstract Thermal conductivity is a crucial parameter for evaluating the quality and thermal effects of ceramic coatings, especially barrier coatings. However, measurement by conventional method involves two problems: (a) it difficult to peel off coating from substrate; (b) even if can be peeled off, still hardly used as standard specimen in test. Therefore, relative was proposed evaluate coating. An analytical relationship among conductivities coating, substrate, coating/substrate composite...
