Summary: Heterogeneous photocatalysis using semiconductor oxide photocatalysts is a promising method for environmental remediation and clean energy generation. Nanostructured photocatalysts with unique size-dependent physicochemical properties have attracted attention, but their recovery from aqueous media is challenging. Supported nanophotocatalysts have been developed to overcome this limitation, leading to improved properties and practical applications. Further research is needed to understand the role of support-photocatalyst interactions in enhancing properties.

Summary: Lowering evaporation enthalpy is crucial for improving solar evaporation rate in solar-driven seawater desalination. This study presents a new approach to lower vaporization enthalpy by introducing heterogeneous interactions between hydrophilic hybrid materials and water molecules. The integration of 2D MoN1.2 nanosheets and rGO nanosheets forms stacked MoN1.2-rGO heterostructures, which significantly improve interfacial solar evaporation due to their massive junction interfaces. Molecular dynamics simulation reveals that the interactions between 2D MoN1.2 and rGO with water molecules lead to an imbalanced water state, breaking the hydrogen bonds and resulting in lowered vaporization enthalpy and improved evaporation rate (2.6 kg m(-2) h(-1)). This research provides a promising strategy for designing 2D-2D heterostructures to regulate evaporation enthalpy for cleaner water production.

Summary: In rare earth nickelates, the metal-to-insulator transition can be explained by an electronic and structural order parameter. The coupling of metal-to-insulator transitions observed at the SmNiO3/NdNiO3 interface is studied using SmNiO3/NdNiO3 superlattices with insulating LaAlO3 spacer layers, revealing that the electronic order parameter is responsible for the coupling. The complete decoupling of the metal-to-insulator transitions by inserting a single unit cell of LaAlO3 between SmNiO3 and NdNiO3 suggests the dominance of the electronic order parameter in controlling the coupling.

Summary: The intermittent behavior of point defects in oxide heterostructures has been discovered using X-ray photon correlation spectroscopy. The local fluctuations between ordered phases in strained SrCoOx with different stability of oxygen vacancies are found to be modulated by the interaction energy between oxygen ions/vacancies and epitaxial strain. This study reveals the influence of defect dynamics on material functionality and opens new avenues for engineering the dynamical response of functional materials in neuromorphic and electrochemical applications.

Summary: PdCoO2 is a complex material with both weakly and strongly correlated electrons co-existing in different layers, with unique physical properties emerging from the electronic coupling between layers. Standing-wave X-ray photoemission spectroscopy and many-body calculations were used to investigate the layer-resolved electronic structure of PdCoO2, providing insights into the inter-layer hybridization in layered quantum materials.

Summary: This paper demonstrates how the composition of bimetallic Fe-Ni exsolution can be controlled by the nature and concentration of oxygen vacancies in the parental matrix, and how this affects the performance of CO2-assisted ethane conversion. The use of mesoporous A-site deficient La0.4Sr0.6-alpha Ti0.6Fe0.35Ni0.05O3+/-delta perovskites enables fast exsolution kinetics of bimetallic Fe-Ni nanoparticles. The control of reduction and growth processes of bimetallic exsolution offers interesting prospects for the design of advanced catalysts based on bimodal nanoparticle heterostructures.

Summary: In this study, van der Waals heterostructures of LSMO and MoS2 were successfully fabricated on Si substrates, showing multiple functionalities. Freestanding LSMO membranes and van der Waals force-mediated transfer were used to overcome the growth process issues. The LSMO-MoS2 heterostructures exhibit gate-tunable rectifying behavior, photodiode characteristics, and electrically tunable magnetoresponse at room temperature due to the colossal magnetoresistance of LSMO.

Summary: This study investigates the initial Coulombic efficiency (ICE) of conversion-type MoO3 and reveals the failure mechanism during delithiation. The highly delithiated outer region of MoO3 particles forms a layer with low electronic conductivity, impeding further delithiation. This finding provides critical guidance for the development of conversion-type anode materials with improved electrochemical reversibility.
