VO2 material, as a promising intercalation host, is widely investigated not only in aqueous lithium‐ion batteries, but also in aqueous zinc‐ion batteries (AZIBs) owing to its stable tunnel‐like framework and multivalence of vanadium. Different from lithium‐ion storage, VO2 can provide higher capacity when storing zinc ions, even exceeding its theoretical capacity (323 mAh g−1), but the specific reason...
Although the research on aqueous batteries employing metal as the anode is still mainly focused on the aqueous zinc‐ion battery, aqueous iron‐ion batteries are considered as promising aqueous batteries owing to the lower cost, higher specific capacity, and better stability. However, the sluggish Fe2+ (de)intercalation leads to unsatisfactory specific capacity and poor electrochemical stability, which...
Sodium‐ion batteries are a promising substitute for lithium batteries due to the abundant resources and low cost of sodium. Herein, honeycomb‐shaped MoSe2/reduced graphene oxide (rGO) composite materials are synthesized from graphene oxide (GO) and MoSe2 through a one‐step solvothermal process. Experiments show that the 3D honeycomb structure provides excellent electrolyte penetration while alleviating...
Rational design and facile synthesis of efficient environmentally friendly all‐inorganic lead‐free halide perovskite catalysts are of great significance in photocatalytic CO2 reduction. Aiming at photogenerated charge carrier separation and CO2 reaction dynamics, in this paper, a CsCuCl3/Cu nanocrystals (NCs) heterojunction catalyst is designed and synthesized via a simple acid‐etching solution process...
Organic–inorganic hybrid perovskite solar cells (PSCs) are among the most promising candidates for the next generation of photovoltaic devices because of the significant increase in their power conversion efficiency (PCE) from less than 10% to 25.7% in past decade. The metal‐organic framework (MOF) materials owing to their unique properties, such as large specific surface area, abundant binding sites,...
Current circulating tumor cells (CTCs) detection strategies based on surface epithelial markers suffer from low specificity in distinguishing between CTCs and epithelial cells in hematopoietic cell population. Tumor‐associated miRNAs within CTCs are emerging as new biomarkers due to their high correlation with tumor development and progress. However, in‐situ simultaneous analysis of multiple miRNAs...
Perovskite‐based oxides attract great attention as catalysts for energy and environmental devices. Nanostructure engineering is demonstrated as an effective approach for improving the catalytic activity of the materials. The mechanism for the enhancement, nevertheless, is still not fully understood. In this study, it is demonstrated that compressive strain can be introduced into freestanding perovskite...
Utilizing electricity and heat from renewable energy to convert small molecules into value‐added chemicals through electro/thermal catalytic processes has enormous socioeconomic and environmental benefits. However, the lack of catalysts with high activity, good long‐term stability, and low cost strongly inhibits the practical implementation of these processes. Oxides with exsolved metal nanoparticles...
MoS2, one of the most valued 2D materials beyond graphene, shows potential for future applications in postsilicon digital electronics and optoelectronics. However, achieving hole transport in MoS2, which is dominated by electron transport, is always a challenge. Here, MoS2 transistors gated by electrolyte gel exhibit the characteristics of hole and electron transport, a high on/off ratio over 105,...
Van der Waals heterostructures based on 2D layered materials have received wide attention for their multiple applications in optoelectronic devices, such as solar cells, light‐emitting devices, and photodiodes. In this work, high‐performance photovoltaic photodetectors based on MoTe2/MoS2 vertical heterojunctions are demonstrated by exfoliating‐restacking approach. The fundamental electric properties...
In article number 1703293, Tie Lin, Weida Hu, Jianlu Wang, and co‐workers present a high performance photovoltaic photodetector based on MoTe2/MoS2 Van der Waals heterojunction. The light‐induced charge transport under different biases is discussed. As self‐powered photodetectors, the vertical 2D p‐n junctions achieve a sensitive response and broad detection wavelength range. These properties indicate...
