Summary: This study focuses on improving material performance through effective modification methods, specifically by incorporating AgI nanoparticles onto hollow multi-shell ZnO microspheres. The heterojunctions formed between these two semiconductors alleviate photo-corrosion for ZnO and enhance photocatalytic stability. Introducing narrow band-gap AgI effectively reduces ZnO's optical band gap, leading to improved photocatalytic performance such as CIP photodegradation and H-2 evolution under simulated solar irradiation.

Summary: In this study, combined and unique MoSe2PS nanostructures were synthesized on nickel foam using a three-step hydrothermal process. Microstructural observations showed a unique morphology of petals covered by elongated nano-blades. The nanostructure exhibited high electrocatalytic performance in the hydrogen evolution reaction, achieving a 90 mV overpotential at a current density of -10 mA/cm2. The near-platinum activity was attributed to the synergistic properties of S and P on MoSe2, as well as the high electrochemical active sites in the specimen. Furthermore, the synthesized electrocatalyst showed excellent stability in the alkaline medium, confirming its potential application in fuel cells and transportation industries.

Summary: Interlayer engineering is a promising strategy to modify the structure of layered vanadium-based oxides for optimized ion-diffusion capability. This study explores the role of interlayer crystal water in tuning the charge storage properties and finds that regulating interlayer water content can enhance the reversibility of zinc ion diffusion and improve the cycling stability of V2O5·nH2O electrodes. Density functional theory calculations suggest that modulated electron structure in V2O5·nH2O materials provides a favorable electrostatic environment for reversible Zn2+ diffusion.

Summary: The study focuses on ice nucleation and growth at the nanoscale, which is important in geological and atmospheric sciences. However, existing transmission electron microscopy approaches have not been successful in directly imaging ice formation. The use of TiO2 radical scavengers in graphene liquid cells is demonstrated to enable the observation of ice nucleation phenomena at low temperatures. Atomic-resolution imaging reveals the nucleation and growth of cubic ice-phase crystals at close proximity to TiO2-water nanointerfaces at low temperatures.

Summary: The researchers used advanced in situ diagnostic tools to track the structural evolution of tunnel-structured MnO2 upon Li+ ion insertion/extraction, and found that the cycling instability originates from a partially reversible phase transition between beta-MnO2 and orthorhombic LiMnO2, as well as the presence of multiple arrow-headed disordered regions at the MnO2/LiMnO2 interface which severely impact the structural integrity of the host material. This finding sheds light on the instability of tunnel-structured materials, suggesting that future strategies should focus on tuning charge transport kinetics for performance enhancement.
