Titanium-based high-entropy alloys (HEAs) have emerged as promising solid-state hydrogen storage materials owing to their structural stability, tunable thermodynamics, and rapid kinetics. This review systematically examines the hydrogen storage behaviour of Ti-based HEAs across three structural categories: body-centered cubic (BCC) single-phase alloys, C14 Laves phase alloys, and multiphase systems containing CsCl-type structures. The high-entropy effect, severe lattice distortion, sluggish diffusion, and cocktail effect collectively enable these alloys to overcome key limitations of conventional materials, including difficult activation, poor reversibility, and insufficient cycling stabilit...

Aqueous zinc-ion batteries (AZIBs) are promising for large-scale energy storage due to their high safety, low cost, and environmental friendliness. However, their practical application is hindered by severe parasitic side reactions and uncontrollable dendrite growth on zinc anodes, leading to rapid performance degradation. Constructing an artificial interphase layer (AIL) on the zinc surface has emerged as an effective strategy to isolate the electrolyte and regulate interfacial electrochemistry. Among various candidates, layered materials (LMs) with two-dimensional structures offer intrinsic advantages-including tunable interlayer channels, mechanical flexibility, and high surface areas—t...

Polymer-derived carbons have emerged as efficient and economical electrocatalysts for energy-related reactions such as oxygen reduction and hydrogen evolution. However, their performance often faces an inherent trade-off between porosity and electronic conductivity, necessitating precise regulation of composition and structure at the molecular level. To enhance the formation of accessible active sites, we construct a series of core@polyaniline precursors with systematically varied organic cores (a nitrogen-rich polymer (NPS), polysaccharide (GluS), and polyaniline (PANI) itself). Metals ions are introduced during the shell polymerization. The resultant core-shell precursors were then subject... More >

Nanomaterials play crucial roles in energy, catalysis, biomedicine, and electronic devices. A systematic and in-depth understanding of the dynamic behavior during structural evolution and practical applications is significant. Liquid phase transmission electron microscopy (LP-TEM) is a powerful in situ characterization technique. It provides atomic-scale resolution and high temporal resolution observation for the evolution of nanomaterials in solution and has become a crucial tool for studying the dynamic processes of nanomaterials. This review summarizes the latest research progress of LP-TEM in nanomaterial nucleation and growth, etching and corrosion, self-assembly, and electrochemical ap... More >

The demand for reliable and sustainable infrastructure necessitates a fundamental shift in engineering materials, moving beyond incremental improvements toward an integrated paradigm combining intrinsic performance enhancement, functional adaptability, and intelligent design. In this perspective, we highlight the key opportunities and challenges of advanced cement-based engineering materials, focusing on high strength-toughness, long-service-life, frontier engineering materials, and intelligent design. These interdependent areas collectively pave the way for a new generation of engineering materials capable of withstanding unprecedented service conditions while substantially reducing environ...

Graphitic carbon nitride (g-C$_3$N$_4$) has garnered interest as a versatile photocatalytic platform owing to its tailorable electronic architecture; however, its solar-to-chemical conversion is bottlenecked by high exciton binding energies and slow charge-carrier transport. To circumvent these impediments, the construction of ``molecular junctions'' within the conjugated polymeric scaffold enables atomically precise modulation of spatial electron configurations. Unlike conventional heterostructures relying on physical contact, molecular junctions employ robust covalent bridging, facilitating molecular orbital hybridization and $\pi$-conjugation. This review summarizes recent advances in mol... More >

The growing demand for high-performance energy storage, particularly in electric vehicles and grid applications, has highlighted the limitations of conventional lithium-ion battery manufacturing. Traditional wet-processing electrode fabrication, though widely used, faces challenges such as solvent waste, limited scalability, and inconsistent microstructures. Dry electrode technology (DET) offers a promising alternative by eliminating solvents and drying steps, enhancing sustainability, cost-efficiency, and performance. This review provides a comprehensive overview of DET, emphasizing key microstructural advantages including uniform material distribution, low ion-transport tortuosity, and sup... More >

The generation of high-brightness white light in laser-illuminated devices is achieved by exciting yellow-green phosphors with a blue laser source. This configuration offers advantages such as high energy density and strong central luminous intensity. Among luminescent materials, LuAG:Ce phosphor ceramics (PCs) are notable for their high thermal stability and luminous output. In this study, LuAG:Ce PCs were produced from co-precipitated monophase nanopowders. The effects of vacuum sintering and air annealing temperatures on their porosity and luminescent properties were investigated. The sample, sintered at 1550°C and subsequently annealed at 1350°C, exhibited 3.5 vol.% porosity, highest r... More >
