Aqueous zinc metal batteries (ZMBs) represent a highly promising solution for sustainable energy storage. However, their large-scale deployment is challenged by critical interfacial instabilities at the anode, including uncontrolled dendrite growth, parasitic hydrogen evolution, and severe corrosion. These issues originate from the inherently disordered and reactive interface between the electrode and the aqueous electrolyte. In response, the construction of an artificial solid electrolyte interphase (SEI) has emerged as a foundational strategy for reconfiguring interfacial dynamics at the micro- and mesoscopic scale. By exerting precise control over ion transport, nucleation, and electrochemical reactivity, an engineered SEI layer can significantly improve Coulombic efficiency and long-term cycling stability. This review systematically examines the pivotal functions and stabilization mechanisms of artificial SEI layers for zinc anodes, discussing design principles, advanced construction methodologies, and performance evaluation under realistic conditions. We comprehensively summarize in-situ and ex-situ construction techniques, evaluate their respective applicability, and offer strategic insights for the rational design of high-performance SEI structures. By synthesizing recent theoretical and experimental advances, this work bridges fundamental research with practical applications, provides deep insights into SEI-mediated interfacial protection, and guides the development of ZMBs toward commercial realization.

Efficient electrochemical energy conversion and sustainable development largely depend on improving the catalytic activity of electrocatalysts. In recent years, exogenous elements, especially rare earth elements, have demonstrated significant potential in modifying transition metal-based electrocatalysts due to their unique electronic structure and chemical properties. This review summarizes recent advances in rare earth-modified catalysts for the oxygen evolution reaction, highlighting their roles in tuning electronic structures, enhancing the exposure of active sites, and lowering the energy barriers of reaction processes. Through strategies such as lattice doping, surface modification, composite structure construction, and defect engineering, rare earth elements have significantly enhanced catalytic performance. This review further delves into the critical challenges confronting rare earth -base d electrocatalysts, encompassing atomic-level structure regulation, cost-effective scalable synthesis, in-depth reaction mechanism elucidation, and durability under practical operational conditions. It systematically explores their prospective applications in emerging renewable electrochemical energy technologies encompassing water-splitting conversion and energy storage application thereby offering critical theoretical insights and defining viable research trajectories for the rational design of efficient electrocatalysts.

Metal single-atom absorbers (M-SAAs) are redefining the frontier of electromagnetic wave (EMW) absorption by exploiting atomically dispersed sites, programmable coordination environments, and strong metal-support interactions. Unlike conventional absorbers, M-SAAs deliver extraordinary dielectric loss efficiency and broadband absorption, thereby opening new avenues for lightweight, wideband, and adaptive EM protection. Despite these advances, the intrinsic dielectric loss mechanisms and the structure–property correlations between coordination environments and dielectric loss remain poorly understood. This review provides the first atomic-scale mechanistic analysis of M-SAAs, offering a comprehensive dissection of their polarization loss mechanisms, a systematic summary of regulation strategies involving metal species, coordination environments, loading densities, and support architectures, and a fundamental elucidation of the underlying principles governing their dielectric performance. Building on these insights, we propose a forward-looking roadmap encompassing scalable and cost-effective synthesis, exploration of non‑carbon supports, multidimensional structural engineering, and the creation of intelligent, dynamically tunable, and programmable absorption systems. We further outline the key challenges and emerging opportunities of M-SAAs in extreme-environment protection, adaptive sensing, and stealth technologies. This work provides both a theoretical foundation and a visionary outlook for accelerating disruptive breakthroughs in EM compatibility and radiation mitigation.

Metal-organic frameworks (MOFs) represent a rapidly evolving class of porous crystalline materials characterized by the modular assembly of metal nodes and organic linkers. While early research predominantly focused on frameworks with uniform metal centers and single organic ligands, recent advancements have steered toward multicomponent MOFs, materials constructed from multiple metal ions and/or diverse organic ligands. These hybrid architectures offer enhanced structural complexity and functional tunability, enabling synergistic properties and broader application scopes. In this review, we systematically summarize the design principles, synthetic strategies, and structural features of multicomponent MOFs. We further discuss their emerging roles in biomedical applications, highlighting how structural complexity supports multifunctionality, present key examples in drug delivery, imaging, and combination therapy, and outline challenges for clinical translation. Finally, we highlight current challenges and future opportunities in this dynamic research area, with an emphasis on structure-function correlation and rational design

Nanozymes, nanomaterials with enzyme-mimicking activities, have emerged as powerful tools in food safety, owing to their excellent catalytic properties and unique physicochemical characteristics. Although significant progress has been made in utilizing nanozymes for the detection or control of contaminants, existing segmented methods often fail to meet the complicated demands of actual food safety environments. In contrast, the integration of detection and decontamination within a unified nanozyme platform represents a more meaningful and promising strategy. Specifically, nanozyme-based “Detection-Plus” is an integrated platform that simultaneously detects and eliminates food safety hazards through catalytic degradation, adsorption, or sterilization, enabling immediate in situ remediation without separate treatment. This review focuses on the design of nanozyme-based platforms that seamlessly integrate detection with subsequent control measures, such as the targeted efficient sterilization of pathogens, and the catalytic removal or degradation of chemical hazards. By unifying these functions, nanozymes open the path toward intelligent response systems capable of providing comprehensive solutions. This review aims to establish a foundational framework and offer a forward-looking perspective on integrated nanozyme technologies, underscoring their potential to transform food safety assurance across the entire production-to-consumption continuum.

The understanding of noncovalent interactions is essential for the rational design and control of material properties. Nonlinear optical (NLO) effects are particularly relevant in this context, as materials with strong NLO responses find applications in areas such as optical communication and signal processing. Computational quantum chemistry has provided valuable insights into the interplay of the electronic and vibrational counterparts of molecular NLO properties, and considerable effort has been devoted to linking these properties with chemical structure. A key aspect is the role of intermolecular interactions, which can significantly modify optical responses and are quantified through interaction-induced (excess) properties. We first present the progress made in analyzing confinement effects, modeled through analytical potentials, on (hyper)polarizabilities of hydrogen-bonded molecular complexes. In doing so, we account for electronic as well as vibrational counterparts. Confinement leads to structural compression, shortening both covalent and hydrogen bonds and increasing vibrational frequencies. The confinement also induces a reduction in the electronic polarizabilities and hyperpolarizabilities, with decreases up to 50% in the second hyperpolarizability under moderate confinement. In contrast, vibrational contributions are less affected, and their relative importance grows under confinement. A breakdown into harmonic and anharmonic terms shows that the latter play a crucial role, especially for vibrational second hyperpolarizabilities. We next focused on our studies on the decomposition of interaction-induced electronic and vibrational (hyper)polarizabilities into terms arising due to the various intermolecular interaction types. For this purpose, we combined the finite-field nuclear relaxation formalism with an interaction energy decomposition scheme. In particular, the decomposition was applied to interaction energy, and the electronic and vibrational contributions to (hyper)polarizabilities, allowing us to quantify how different interaction types selectively influence each property. These results highlight the intricate interplay of interaction types underlying excess electric properties. Finally, we extended the decomposition scheme to analyze interaction-induced changes in IR intensities. By establishing a direct link between nuclear-relaxation polarizabilities and harmonic IR intensities, we were able to partition mode-specific intensity changes into contributions due to interaction types. Applications to stacked, hydrogen-bonded and halogen-bonded complexes are discussed in the review. The new methodology thus provides new insights into the microscopic origins of vibrational spectroscopic signatures of intermolecular interactions.

Halogen bonding (XB) has emerged as a versatile non-covalent interaction capable of directing solid-state assembly and modulating photophysical processes in organic and coordination-based materials. Among various XB motifs, CI⋯π, CI⋯N, and CI⋯O interactions provide unique electronic coupling pathways that can enhance spin–orbit coupling (SOC), suppress non-radiative decay, and promote highly emissive triplet states, offering a powerful design platform for room-temperature phosphorescence (RTP). This review summarizes recent advances in XB-assisted luminescence control, with a particular focus on phosphorescent co-crystals and halogen-bonded coordination systems. We first outline the fundamental photophysical consequences of symmetry breaking, heavy-atom effects, and through-space charge-transfer mediated by XB, discussing how these factors accelerate intersystem crossing and reinforce triplet exciton stabilization. We then highlight key structure–property relationships, including the impact of XB topology, polarizability, and halogen bond directionality on SOC enhancement, emission lifetime, and quantum efficiency. Representative systems demonstrate that co-crystals dominated by CI⋯π interactions exhibit longer phosphorescence lifetimes (up to microsecond scale) and improved quantum yields, consistent with SOC-driven emission enhancement. Additionally, we discuss the emerging roles of XB networks in mechanochromic, thermochromic, and afterglow modulation, along with external-stimuli-responsive emission switching enabled by XB reorganization. Finally, we address remaining challenges in quantitative XB–photophysics correlation, predictive crystal engineering, and strategies for achieving higher ΦP and controlled color tunability. The review concludes with a perspective on how rational XB design can expand the scope of functional organic phosphors for sensing, information encryption, bioimaging, and optoelectronic applications.

This review explores the role of noncovalent interactions (NCIs) in governing selectivity in polymerization catalysis, integrating evidence from experimental studies and density functional theory (DFT) calculations. The discussion covers a wide range of catalytic systems, from α-olefin polymerizations mediated by transition-metal complexes to the ring-opening (co)polymerization of biodegradable polymers promoted by organometallic and organocatalytic species. Analysis of NCIs through DFT modeling highlights their crucial influence on catalyst performance, emphasizing how interactions among the catalyst, monomer, and growing polymer chain may affect polymerization selectivity. Particular attention is given to representative cases where NCIs, such as hydrogen bonding and C–H⋯F interactions, play a crucial mechanistic role. Finally, the review extends the discussion to the contribution of NCIs in polymer stereocomplexation, underscoring their impact not only on polymerization mechanisms but also on the resulting material properties.

Lanthanide-doped upconversion nanoparticles (Ln-UCNPs) are especially useful in clinical settings for diagnostic as well as magnetic resonance imaging tests. The emergence of biological frontier fields like precision theranostics, gene editing and optogenetics presents both exceptional opportunities and unprecedented challenges for the bio-application of luminescent nanomaterials. Collectively, these characteristics render Ln-UCNPs highly preferred for cutting-edge bioanalytical and theranostic uses, which have been thoroughly investigated. Recently, as upconversion synthesis technology has matured and various disciplines have become more integrated, significant new advancements have been made in the biological application research of upconversion. In this comprehensive review, we highlight that a deeper understanding of the essential role of rare-earth doping is crucial for developing a wide range of functional nanomaterials for practical applications. We will also explore the advancements in rare-earth based nanomaterials, including the preparation of core and core-shell nanoparticles.
