Summary: Alkali metals (Li, Na, and K) show promise as high-performance rechargeable alkali metal battery anodes due to their high theoretical specific capacity and low electrochemical potential. However, challenges such as high chemical reactivity, uncontrolled dendrite growth, unstable solid electrolyte interphase, and volume expansion during cycling processes hinder their practical application. The introduction of carbon nanotube-based nanomaterials in alkali metal anodes provides a solution to these issues. These nanomaterials with high specific surface area, superior electronic conductivity, and excellent mechanical stability have attracted considerable attention. This review summarizes recent progress on the application of carbon nanotube-based nanomaterials in stable and dendrite-free alkali metal anodes, discusses the merits and issues of alkali metal anodes, as well as their stabilizing strategies, and explores the relationship between synthesis methods, nano- or microstructures, and electrochemical properties of carbon nanotube-based alkali metal anodes. Additionally, advanced characterization technologies on the reaction mechanism of carbon nanotube-based nanomaterials in alkali metal anodes are reviewed. Finally, the challenges and prospects for future study and applications of carbon nanotube-based AMAs in high-performance alkali metal batteries are discussed.

Summary: Nanoparticle catalyst materials, particularly Pt nanoparticles, play a crucial role in sustainable development, especially in catalysis and fuel cell technologies. Temperature has an effect on the size of Pt nanoparticles, but it is not as significant as for other materials. Control over sputtering power, time, and postheat treatment can slightly influence particle size, highlighting the importance of temperature during sputtering. Increasing the temperature of the liquid substrate during sputtering can lead to a small increase in particle size, with high temperatures beneficial for achieving Pt nanoparticles larger than 2 nm.

Summary: With the use of anion template-driven self-assembly, we have achieved precise control over the shape and size of silver nanoclusters, reporting the atomically precise structures of Ag37 and Ag46. The results reveal that Cl- ions serve as both local and global templates in Ag37, while CrO42- ions function as local templates with Cl- ions as global templates in Ag46. By utilizing the deep cavity of thiacalix[4]arene with an extended phenyl group, Ag46 has been successfully used as a host material for dye adsorption depending on the charge and size of organic dyes. The study fills the knowledge gap in understanding the directing role of heteroanions in dictating the shape and size of nanoclusters at the atomic level.

Summary: Metal-organic frameworks (MOFs) have the potential to promote the redox reaction of sulfur species (RRS) and suppress the shuttle effect in lithium-sulfur batteries (LSBs). However, most MOFs are inert in accelerating RRS due to the lack of exposed polar catalytic sites. In this study, a universal strategy is proposed to modify MOFs and expose catalytic metal clusters, resulting in vastly improved performance of LSBs.

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.
