Summary: Metal-CO2 batteries, especially Li-CO2 and Na-CO2 batteries, are considered as ideal energy storage systems due to their high energy density and remarkable CO2 capture capability. However, the practical application of these batteries is limited by problems such as carbonate accumulation, which cause large polarization and poor reversibility. Therefore, the design of efficient catalysts is crucial for improving the electrochemical performance of metal-CO2 batteries. In this study, sea urchin-like ?-MnO2 was used as the cathode material for Li/Na-CO2 batteries, resulting in low overpotentials and excellent catalytic activity. The findings provide a promising guideline for designing efficient electrocatalysts for high-performance metal-CO2 batteries.

Summary: In this study, it was found that the Ru/CeO2 catalyst exhibited high CO2 conversion (86%) and CH4 selectivity (100%) with excellent stability of 30 hours, due to the presence of abundant oxygen vacancies and weak basic sites. The in-situ DRIFTS and DFT calculations revealed that b-HCOO* was the key intermediate in the hydrogenation route on the Ru/CeO2 catalyst, being more easily hydrogenated to methane than m-HCOO*. This systematic study highlights the importance of precise tailoring of the synergistic relationship between oxygen vacancies and basic sites for achieving desired performance in CO2 methanation.

Summary: Doping and compositing of Co-MnO2 with carbon nanotubes (CNTs) enhances the capacity and stability of & delta;-MnO2 used as electrode material for zinc-ion batteries (ZIB). By hydrothermal reaction, MnO4- and Mn2+ are doped into the CNT framework with the presence of Co2+ to prepare Co-MnO2/CNTs material. The ZIB with Co-MnO2/CNTs exhibits a high specific capacity of 365 mA h g(-1) at a current density of 0.2 A g(-1) and retains 94.6% of the capacity after 1500 charging and discharging cycles at 1 A g(-1), outperforming ZIBs with & delta;-MnO2 and Co-MnO2. Diffusion-controlled processes dominate in Co-MnO2/CNTs ZIBs.

Summary: It is costly to synthesize cathode materials through the solid reaction of raw materials at relatively high temperatures due to its high energy consumption. Here, we use LiCoO2 as a model material to demonstrate a novel method for synthesizing cathode materials within 120 s at temperatures as low as 260 degrees C under an AC electric field. The proposed synthesis method could provide a cost-effective pathway to synthesize different cathode materials.

Most antibodies targeted a non-neutralizing S2 epitope, but 11 antibodies targeting the stem helix showed neutralizing activity against different betacoronavirus lineages. These findings revealed a class of IGHV1-46/IGKV3-20 antibodies that can broadly neutralize betacoronaviruses by targeting the stem helix.

Summary: An additive-assisted airflow drying (AAD) method is reported to fabricate mixed-halide inorganic perovskite films in ambient air, achieving pinhole-free films with low defect density. CsPbI2.25Br0.75 PSCs show an improved efficiency of 18.49%, the highest for wide-bandgap (>1.8 eV) inorganic PSCs. PSCs made under moderate relative humidity (40-50%) achieve an efficiency of 17.08%. Additionally, CsPbI2Br and CsPbIBr2 PSCs achieve PCEs of 17.39% and 11.54% respectively, among the best for CsPbI2Br and CsPbIBr2 PSCs. This work provides a convenient and efficient method for fabricating efficient inorganic PSCs in ambient air.

Summary: This study proposes using silicon nanoparticles as electrolyte additives to regulate the uniform electrodeposition of zinc in aqueous zinc-ion batteries (ZIBs). The silicon layer helps lower the nucleation energy barrier for the zinc anode by regulating the interfacial charge distribution. Experimental results show that Zn|Zn symmetric cells with nano-Si electrolyte additives achieve remarkable cycling stability for 1250 cycles at 5 mA cm(-2). Coupling the zinc anode with NaV3O8 cathodes in ZIBs also results in a high reversible capacity of 250 mAh g(-1) and improved capacity retention after long-term cycling.

Summary: Prussian blue analogues (PBAs) have high theoretical energy density and low cost, but their high water and vacancy content lower the energy density and pose safety issues. A potassium-ions assisted strategy is proposed to synthesize highly crystallized PBAs, which exhibit increased redox potential and high energy density of approximately 450 Wh kg(-1). In addition, unconventional highly-reversible phase evolution and redox-active pairs were identified for the first time, and the preferred guest-ion storage sites and migration mechanism were systematically analyzed through theoretical calculations.

This study reports a convenient and robust strategy using stencil printing liquid metal conductor on water-soluble electrospun film to craft flexible transient circuits for human-machine interaction. The circuits feature high-resolution, customized patterning viability, attractive permeability, excellent electroconductivity, and superior mechanical stability due to the liquid conductor within the porous substrate. These circuits also display noncontact proximity capabilities while maintaining compelling tactile sensing performance, making them ideal for wearable sensors with multifunctionality in information transfer, smart identification, and trajectory monitoring. An intelligent human-machine interface composed of these flexible sensors allows for wireless object control and overload alarm. The transient circuits can be quickly and efficiently recycled, offering high economic and environmental values. This work opens possibilities for high-quality flexible and transient electronics in advanced soft and intelligent systems.
