2D magnetic materials have aroused widespread research interest owing to their promising application in spintronic devices. However, exploring new kinds of with better stability and realizing batch synthesis remain challenging. Herein, the air-stable Cr5 Te8 ultrathin crystals tunable thickness via tube-in-tube chemical vapor deposition (CVD) growth technology is reported. The importance CVD growth, which can significantly suppress equilibrium shift decomposition direction facilitate that...
Abstract Molten salt aluminum-sulfur batteries are based exclusively on resourcefully sustainable materials, and promising for large-scale energy storage owed to their high-rate capability moderate density; but the operating temperature is still high, prohibiting applications. Here we report a rapid-charging aluminium-sulfur battery operated at sub-water-boiling of 85 °C with tamed quaternary molten electrolyte. The alkali chloroaluminate melt – possessing abundant electrochemically active...
Abstract Sodium‐ion batteries (SIBs) present a promising avenue for next‐generation grid‐scale energy storage. However, realizing all‐climate SIBs operating across wide temperature range remains challenge due to the poor electrolyte conductivity and instable electrode interphases at extreme temperatures. Here, we propose comprehensively balanced by pairing carbonates with low‐freezing‐point low‐polarity ethyl propionate solvent which enhances ion diffusion Na + ‐desolvation kinetics sub‐zero...

Great achievements have been made exploring linear optical, mechanical, photoelectric properties nanosheets. However, nonlinear nanosheets their applications...
More than a decade after the first theoretical and experimental studies of spin Hall conductivity (SHC) Pt, both its dominant origin amplitude remain in dispute. We report determination rapid variation intrinsic SHC Pt with carrier lifetime (τ) dirty-metal regime by incorporating finely dispersed MgO intersite impurities into while maintaining essential band structure. This conclusively validates prediction that should be dominated contribution, decrease rapidly shortening τ. When...
Abstract Surface engineering has been found to be effective in promoting the catalytic activities of noble‐metal‐based nanocatalysts. In this contribution, by using PtCu x Ni ternary alloy nanocrystal (NC) as model catalyst, a surface tungsten(W)‐doping strategy, combining oxidative acid treatment protocol, can effectively boost electrocatalytic NCs oxygen reduction reaction. The W‐doped catalysts show obvious enhancement electrochemical area and mass activity slightly enhanced specific...
Spin backflow and spin-memory loss have been well established to considerably lower the interfacial spin transmissivity of metallic magnetic interfaces thus energy efficiency spin-orbit torque technologies. Here we report that at Pt-based heavy metal/ferromagnet can be effectively eliminated by inserting an insulating paramagnetic NiO layer optimum thickness. The latter enables thermal magnon-mediated essentially unity spin-current transmission room temperature due enhanced effective...
To avoid carcinogenicity, formaldehyde gas, currently being only detected at higher operating temperatures, should be selectively in time with ppb concentration sensitivity a room-temperature indoor environment. This is achieved this work through introducing oxygen vacancies and Pt clusters on the surface of In2O3 to reduce optimal temperature from 120 40 °C. Previous studies have shown that water participates competitive adsorption sensor surface. Here, we experimentally confirm adsorbed...
Photogenerated charge transfer can be tuned by crystal face controlling and heterostructure engineering. However, it is exceptionally challenging to understand the separation process of carriers, especially on facet junction. Here, we show a pathway carriers in (111)/(100)CeO2–x nanomaterials as "X-Scheme junction" using selected region electron energy-loss spectroscopies. The driving force for attributed localized electronic band structures' asymmetry ceria, which gathers photogenerated...
Abstract Sodium‐ion batteries (SIBs) hold great promise for next‐generation grid‐scale energy storage. However, the highly instable electrolyte/electrode interphases threaten long‐term cycling of high‐energy SIBs. In particular, cathode electrolyte interphase (CEI) at high voltage causes persistent decomposition, transition metal dissolution, and fast capacity fade. Here, this work proposes a balanced principle molecular design SIB electrolytes that enables an ultra‐thin, homogeneous, robust...

Abstract For Pd‐based alloy catalysts, the selection of metallic alloying elements and construction composition‐gradient surface subsurface layers are critical in achieving superior electrocatalytic activities in, e.g., oxygen reduction reaction (ORR). Based on Pd‐containing alloy, highly monodispersed PdCuNi ternary nanocrystals prepared through a wet‐chemical approach, solution‐based oxidative treatment protocol is utilized to activate nanocrystals. A drastically enhanced ORR activity can...
Conventional solid-to-solid conversion-type cathodes in batteries suffer from poor diffusion/reaction kinetics, large volume changes and aggressive structural degradation, particularly for rechargeable aluminium (RABs). Here we report a class of high-capacity redox couples featuring solution-to-solid conversion chemistry with well-manipulated solubility as cathodes-uniquely allowed by using molten salt electrolytes-that enable fast-charging long-lived RABs. As proof-of-concept, demonstrate...
