Summary: The successful growth of self-catalyzed nanowires depends on the effective V/III ratio at the initial growth stage, which should be high enough to allow nucleation to extend to the entire contact area between the droplet and substrate, elevating the droplet off of the substrate, but not too high to keep the droplet. Additionally, cluster growth between nanowires is also initiated from large droplets. This study provides insights into the cluster formation mechanism from the growth conditions and can guide high-yield nanowire growth.

Summary: Metal-organic frameworks (MOFs) have advantages in improving the structure and properties of metal-based active materials, and a novel electrode material Ni-Co-Se/C@CuO is obtained by integrating Ni-Co-MOF with pre-oxidized Cu mesh. Ni-Co-Se/C@CuO exhibits superior electrochemical performance compared to Ni-Co-MOF@CuO, including higher specific capacity, lower resistivity, richer redox activity, and more favorable diffusion-dominated storage mechanism. When assembled as a hybrid supercapacitor (HSC) with rGO, Ni-Co-Se/C@CuO shows a high energy density of 42 W h kg(-1) at a power density of 2 kW kg(-1) and maintains its capacity retention even after 20,000 cycles. The improved capacity performance of Ni-Co-Se/C@CuO is attributed to its unique and preserved heterostructure with enhanced metallic properties. Such evaluation of novel electrodes with superior properties may benefit next-generation electrodes for supercapacitor devices.

Summary: In this study, Co(OH)F was used as a novel fluorine-containing oxidizer in Al-based MIC and vertically aligned Co(OH)F@Al nanobelt arrays with tunable morphology were fabricated via hydrothermal synthesis and electron beam evaporation. It was found that Co(OH)F@Al composites achieved main exothermal reaction before melting of Al regardless of morphology and equivalence ratio, attributed to the etching of Al2O3 shell by HF released from Co(OH)F. A phenomenological model was proposed to elucidate the effect of microstructure on the actual specific heat release.

Summary: Metal-organic frameworks (MOFs) are well-investigated nanomaterials with high surface area and customizable porosity. They are used as templates to achieve desired properties in MOF-based nanomaterials for energy storage systems. MOF-derived materials such as porous carbon, metal/metal oxide, and metal/metal oxide@C have shown excellent performance in electrochemical energy storage devices. However, there is a lack of exploration in the derivation of MOFs into chalcogenide compounds like sulfides, selenides, and tellurides. This review discusses the development and challenges of MOFs in obtaining MOF-derived transition metal chalcogenides (TMCs) and explores their applications in batteries, supercapacitors, and electrocatalysis.

Summary: MXene, a two-dimensional transition metal carbide, nitrides, and/or carbonitrides, shows great potential in various research fields due to its excellent conductivity, hydrophilicity, and abundant surface functional groups. However, challenges in aggregation and low stability greatly limit its applicability.
