Porous organic frameworks including metal–organic frameworks (MOFs), covalent organic frameworks (COFs), and hydrogen-bonded organic frameworks (HOFs), have emerged as structurally diverse and functionally tunable platforms in advanced materials science. Among these, stimuli-responsive porous organic frameworks that undergo reversible structural or physicochemical transformations under external stimuli such as temperature and light have attracted increasing attention. This review provides a critical overview of recent advances in the design, mechanisms, and functions of thermal- and photo-responsive porous organic frameworks. We categorize response strategies according to framework type and responsive element, and highlight how these features contribute to dynamic performance across multiple length scales. Applications such as spatiotemporally controlled drug release, selective gas separation, and switchable enzyme-mimetic catalysis are discussed as model systems to illustrate the functional impact of stimuli responsiveness. Despite recent progress, challenges remain in achieving high responsiveness without compromising stability, in tuning selectivity toward specific stimuli, and in integrating these systems into real-world applications. Looking ahead, a deeper understanding of structure–response correlations, coupled with advances in in situ characterization and computational modeling, will be key to unlocking the full potential of stimuli-responsive porous organic frameworks in next-generation adaptive systems.

However, conventional gas separation technologies often face limitations, including low selectivity, high energy consumption, and operational inefficiencies. Polymeric nanocomposites (PNCs) have developed into capable materials by overcoming these challenges. Incorporating nanomaterials into polymer matrices empowers the advancement of sophisticated membrane technologies with superior mechanical stability, selectivity, and permeability, making them ideal candidates for sustainable gas separation treatments. This review provides an in-depth examination of the latest advancements in PNCs for gas separation, with a focus on their potential environmental applications. It covers key aspects, including the fundamentals of PNCs, their physical and chemical properties, polymer selection criteria, gas separation mechanisms, and their applications in environmental gas purification. Additionally, it discusses the limitations and challenges of these materials and presents perspectives on how innovations in material design and fabrication techniques can further enhance their efficiency. Given the increasing demand for efficient and environmentally friendly gas separation technologies, this review serves as a critical resource for scholars, policymakers, and industry professionals seeking to develop next-generation materials for environmental sustainability.

The multiscale pore-fracture interface in coal forms the fundamental physical basis governing both coalbed methane (CBM) storage-transport behavior and CO2 geological storage efficiency. This review systematically discusses the principle of small angle scattering (SAS) technology in the analysis of coal matrix pore interface, and focuses on the frontier application of coal-fluid interface in terms of geometry, physicochemical properties and dynamic evolution. Results indicate that SAS can nondestructively quantify the entire pore system, including closed pores. Moreover, the predominance of closed pores in quantity and distribution is strongly affected by coal type and tectonic stress. The unique advantages of in-situ SAS technology in real-time tracking of interface dynamics and complex response mechanisms (such as expansion/contraction, pore damage and structural rearrangement of coal matrix under external fields such as gas adsorption, stress loading and pyrolysis) are analyzed. Through the interface fractal, SAS provides key parameters for quantitative description of interface complexity and its internal correlation with coal chemical composition. The application of “contrast-matching small-angle neutron scattering” (CM-SANS) in visualization of fluid accessibility, the key role of time-resolved small angle scattering technology in capturing instantaneous dynamic structural response of rock mass, and the cutting-edge technology of multi-scale and multi-dimensional data fusion are systematically discussed. The purpose of this review is to provide robust micromechanical support for understanding the coal-fluid interaction, thereby promoting innovation in energy and environmental engineering technologies such as CBM efficient development and carbon capture, utilization, and storage (CCUS).

Recent advances have expanded superwetting system from single to multiple superlyophobicity, enabling diverse superlyophobic interfaces. However, current research lacks a comprehensive understanding of how surface chemistry governs superlyophobic properties-knowledge that is essential for rationally designing superwetting behaviors. This article highlights design principles of fine-tuning surface chemistry, fabrication strategies and multifunctional applications of diverse superlyophobic interfaces, emphasizing how lyophobic and lyophilic components of surface govern single and multiple superlyophobicity. Based on surface thermodynamics, the preparation methods, regulation strategies and underlying mechanism for various types of superlyophobic interfaces are systematically analyzed. Furthermore, the article distills representative applications that align with various single and multiple superlyophobic interfaces under complex environmental conditions and functional requirements, offering a foundational framework for their practical utilization. By establishing surface chemistry design criteria, we provide insights into the rational control of single or multiple superlyophobicity and the integration of additional functionalities, thereby enabling the exploration of novel wetting states and multifunctional interfaces. Finally, we outline future challenges and emerging trends, including advances in multiple superlyophobic mechanisms, innovative fabrication techniques, and next-generation performance enhancements for these interfaces.

Geological storage of carbon dioxide is widely regarded as an effective approach to reduce atmospheric CO2. Several geological formations have been investigated for CO2 sequestration, including depleted hydrocarbon reservoirs, unmineable coal seams, and basaltic formations that enable mineral trapping. Confined saline aquifers are generally viewed as a favorable option because of their global distribution. Storage safety in confined saline aquifers remains a major public concern due to significant hydrological challenges, particularly the potential leakage of brine and CO2 into overlying freshwater aquifers. The leakage processes of brine and CO2 have been extensively studied, yet their distinct mechanisms are often conflated in the literature. Brine leakage is primarily pressure-driven, whereas CO2 leakage is governed by saturation dynamics. Leakage may also arise from compromised aquiclude integrity, microfractures, or poorly sealed abandoned wells that act as conduits for vertical fluid migration. In response, numerous analytical, semi-analytical, and numerical models have been developed to describe and quantify leakage behavior. This review critically examines these modeling approaches, highlighting their underlying assumptions, applicability, and limitations, and identifies key knowledge gaps to guide future research on subsurface CO2 containment.

Clays play a critical role in natural and engineered systems due to their unique layered structures, surface reactivity, and capacity to regulate fluid and solute behavior. From carbon sequestration and contaminant containment to enhanced oil recovery and subsurface energy storage, understanding clay–fluid interactions is essential for predicting system performance of sediment complex. However, most atomistic studies have relied on idealized infinite-sheet models, which overlook critical features such as edge terminations, finite particle size, and morphological heterogeneity—elements that dominate in real clay aggregates. This review addresses this knowledge gap by synthesizing recent advances in finite-particle modeling, which capture edge chemistry, stacking disorder, and confinement-driven transport dynamics. We examine the structural construction of finite clay models, discuss key force field developments, and highlight how finite systems alter hydration, ion adsorption, and molecular diffusion. Particular focus is placed on the emergence of anisotropic pore geometries, dynamic confinement effects, and size-dependent mechanical behavior. By bridging infinite and finite modeling paradigms, this review aspires to contribute to on-going efforts in modeling, experimentation, and multiscale integration toward more representative depictions of clay behavior across diverse applications.

Biomaterials are natural or synthetic materials designed to substitute or improve the performance of bone or living tissues. Over the past two decades, bioglass (BG) has emerged as a particularly promising biomaterial, consistently demonstrating its capacity to stimulate bone regeneration and osseointegration. Bioglass composites benefit from the addition of natural or synthetic polymers, which not only boost their mechanical integrity but also make them more versatile in terms of fabrication into different shapes and sizes. Of particular interest is typical polysaccharide, chitosan (Ch), a non-toxic, biocompatible, and biodegradable derived from renewable sources, which naturally possesses antibacterial activity. The strategic combination of bioglass and chitosan leverages their individual strengths to create bioactive composite coatings with significant potential for diverse biomedical applications. These novel multilayer/multicomponent coatings deposited on solid support/implant are being actively investigated for their utility in: antimicrobial applications, drug delivery systems, wound dressings, skin regeneration, bone repair, general tissue engineering. Ongoing research is focused on addressing the challenges and exploring the prospects of bioglass/chitosan-based biomaterials to optimize their design and tailor their properties for future advancements in these crucial biomedical fields.

The reliability of power transformers is greatly influenced by properties of uninhibited naphthenic base mineral oil (UNMO) used as an insulating oil. This study aims to investigate effects of ZnO nanoparticles on the thermophysical and insulating properties of UNMO. X-ray diffraction testing was conducted to verify the nanoscale size of nanoparticles, with results analyzed using the Scherrer method and William Hall method, including UDM, USDM, and UDEDM approaches. Nanoparticles sizes determined by these methods were 21.65, 26.20, 35.92, 35.37, and 36.01 nm, respectively. These measurements confirmed the samples as nanoparticles with sizes below 100 nm. Nano insulating liquid was prepared using a two-step method with concentrations of 0.01, 0.05, and 0.1 wt%. The results demonstrate that the addition of ZnO nanoparticles simultaneously enhances dielectric breakdown strength and thermal conductivity, while also increasing dielectric losses and electrical conductivity. A highly significant improvement of 42.76% in ACBDV was observed, indicating superior resistance to electrical puncture. Thermal conductivity was also enhanced by up to 81.83%, promising improved heat dissipation and reduced operational temperatures, which contributes to extended transformer lifespan. Conversely, the tan δ and electrical conductivity increased by 44.83% and 49.00%, respectively, representing a trade-off in the form of higher dielectric losses and potential leakage currents.

Large-scale underground hydrogen storage (UHS) has emerged as a crucial strategy for mitigating fluctuations in hydrogen demand. Wettability at the hydrogen-fluid-rock interface is a critical factor controlling hydrogen storage capacity and recovery efficiency. This review systematically elucidates the evolution of multiphase interfacial wettability during hydrogen storage, covering reservoir types, characterization techniques, key influencing factors, and their multiscale impacts. 4D X-ray microscopy offers a promising approach for characterizing the dynamic evolution of interfacial wettability under in-situ conditions. The review provides an in-depth discussion of the factors governing wettability, including geological media, gas composition, salinity, bubble size, temperature, pressure, microorganisms, and organic acids. There is currently a lack of research on the evolution of interfacial wettability under the coupled influence of multiple factors. It is worth noting that nanofluids hold significant potential for wettability control. The discussion spans from the molecular to the macro scale, detailing how the evolution of interfacial wettability impacts adsorption, saturation, gas column height, and relative permeability modeling. The coupled interaction between interfacial wettability and dynamic behavior exerts a complex influence on hydrogen saturation. Macro-scale simulation of UHS requires incorporating mixed wettability into the relative permeability hysteresis model. This review provides fundamental insights into the evolution of interfacial wettability, offering guidance for enhancing the safety and efficiency of UHS.
