Summary: The bis(pyridyl)amine-bipyridine-iron(II) framework (Fe(BPAbipy)) complexes 1-3 exhibit a multistep nature in CO2 reduction, with Fe-CO formation being the rate-determining step for selective CO2-to-CO reduction. Certain functional groups, such as the pendant alpha-OH group, play key roles in initiating H-2 evolution. This catalyst system shows promise for robust CO2 reduction by photocatalysis through advanced multi-electron and multi-proton transfer processes.

Summary: In this study, large pressurized monolayer TMD domes were fabricated using proton irradiation, and their SHG performance was comprehensively investigated. The results showed that the intensity of SHG was effectively enhanced by around two orders of magnitude at room temperature. This giant enhancement was attributed to the distinct separation distance induced by capped pressurized gas and the hemi-spherical morphology, which enabled constructive optical interference. Moreover, the unique divergent strain field in TMD domes promoted the first experimental study on the anisotropic nonlinear optical behavior based on biaxial strain conditions.

Summary: Researchers adopt a higher operating voltage to expand the application scope and market share of LCO, but this causes capacity decay and safety issues. Coating Li3PO4 onto an LCO cathode increases the energy density of lithium-ion batteries. Enhancing the conductivity of cathode materials is crucial for raising their operating voltage. A direct coprecipitation method was used to coat Li3PO4 onto an LCO surface, balancing ionic conductivity and chemical stability. The optimized LP-3 cathode delivers a high initial discharge capacity of 181 mA h g(-1) at 0.5C, with a capacity retention of 75% after 200 cycles. This study introduces a competitive strategy for producing a high-voltage LCO cathode.

Summary: Layered double-hydroxides (LDHs) have been extensively researched for their advantages in lithium-ion batteries (LIBs), but their poor electronic conductivity, volume change, and ion diffusion limitations hinder their performance. To overcome these challenges, expanded graphite (EG) was used as a conductive additive to anchor Ni2Co-LDH on its surface. The resulting Ni2Co-LDH/EG composites exhibited significantly enhanced charge-storage capacities and battery-like behavior. Density functional theory (DFT) calculations suggest that the stable Li-ion intercalation in Ni2Co-LDH/EG is attributed to the interaction energy and overlap of lithium and carbon.

Summary: This study demonstrates the improvement of mechanical properties and reduction of coefficient of thermal expansion (CTE) in graphene oxide (GO)/epoxy (EP) nanocomposites by enhancing the interface between GO and EP through functionalization and incorporating rigid-flexible interphases. The results reveal that the SiO2-PEA-GO hybrid exhibits better strengthening and toughening effects, as well as lower CTE, compared to the PEA-GO hybrid due to the presence of rigid-flexible interfaces with higher bonding strength and better energy dissipation mechanisms. Additionally, the nanocomposites with longer polyetheramine (PEA) molecules in the rigid-flexible interphases demonstrate higher strength and toughness, while maintaining a lower CTE. This work provides a promising strategy for constructing adjustable flexible-rigid interfacial structures and offers potential in developing GO/EP nanocomposites with high mechanical properties and low CTE.
