Owing to their inherent safety attributes, aqueous zinc-ion batteries (AZIBs) are progressively recognized as highly promising candidates for next-generation energy storage technologies. Despite molybdenum disulfide (MoS₂) having surfaced as a viable electrode material, its real-world utilization remains constrained by sluggish ion diffusion processes and restricted specific capacity. …

In this study, density functional theory (DFT) calculations were employed to investigate the interactions between structurally similar small molecules, 4-hydroxybenzoic acid (4-HBA) and 4-hydroxyphenylacetic acid (4-HPAA), and Au-enhanced substrates in the context of surface-enhanced Raman scattering (SERS). The calculated molecular electrostatic potential (ESP) results indicate that both molecul…

In biological neural systems, learning and memory rely on ion transport in liquid environments. Owing to their biomimetic signaling mechanisms, nanofluidic memristors with tunable conductance can emulate synaptic memory and plasticity, having attracted significant attention. In this work, we propose a nanofluidic memristor based on the ionic liquid-electrolyte solution interface at a conical quar…

Thin liquid films exhibit rich instability and rupture dynamics that critically impact coating performance across many applications. In this work, we use the lattice Boltzmann method (LBM) simulations within a lubrication-theory framework to systematically quantify how film thickness, surface energy, wettability, and intermolecular forces govern dewetting kinetics and long-time morphology. Master…

Passive radiative cooling (PRC) shows potential for energy savings, especially in the construction and transportation industries. However, it is prone to efficiency loss due to influences from the environment. To address this challenge, we constructed a ZnAl layered double oxide (ZnAl-LDO) substrate, which has optical selectivity, and modified it with a cross-linked surfactant of SiO₂/…

Electroless copper plating is a vital technique for depositing uniform and conductive copper layers, particularly for fabricating copper-coated polymer microspheres used in anisotropic conductive adhesives. However, achieving high-quality coatings on polymer microspheres remains challenging due to their inherent catalytic inertness and the lack of reliable evaluation metrics. Herein, copper nanop…

Adsorption of aniline and pyridine on the H- and HO-terminated Si(100) surfaces has been investigated by X-ray photoelectron spectroscopy (XPS), atomic force microscopy (AFM), and density functional theory (DFT) calculations. Surface functionalization reactions were conducted under solution-chemistry conditions and an inert atmosphere, and show that adsorption proceeds very differently for anilin…

Metal-organic frameworks (MOFs) have emerged as a versatile and tunable platform for creating coordinatively unsaturated single-metal sites within inorganic-organic hybrid porous materials. Notably, Co-, Ni-, and Zn-based metal-organic frameworks, characterized by their well-defined structures, extensive surface areas, and chemically and structurally homogeneous active sites, have gained prominen…
