The growing demand for sustainable food packaging has driven innovation in electrospun nanofibers integrated with bioactive phenolic acids. This review highlights the pivotal role of phenolic acids—such as tannic acid, gallic acid, and tea polyphenols—in enhancing the functionality of biodegradable polymer matrices (e.g., PLA, PVA, chitosan) made from electrospun nanofibers. These compounds improve mechanical strength, thermal stability, and barrier properties through hydrogen bonding and covalent interactions, while their antioxidant and antimicrobial activities effectively combat oxidative spoilage and microbial contamination. Case studies demonstrate their efficacy in extending the shelf life of perishable foods, including fruits, meats, and seafood. Controlled release mechanisms, achieved via advanced electrospinning techniques like coaxial or multilayer architectures, ensure sustained bioactivity. Challenges in optimizing release kinetics and scaling production are discussed. By bridging material innovation with practical food preservation needs, phenolic acid-functionalized nanofibers emerge as a versatile, eco-friendly solution for next-generation active packaging systems.

Oscillatory gas supply (OGS) has emerged as an effective method to enhance gas-liquid mass transfer in industrial applications by minimizing bubble size at submerged orifices. Compared to traditional steady gas supply (SGS), OGS facilitates premature bubble detachment from microporous diffusers, thereby reducing coalescence and enhancing transport phenomena. This improvement leads to lower energy consumption across sectors such as environmental engineering and chemical processing. This review critically examines the feasibility and applications of OGS in multiphase flow systems, including wastewater treatment, flotation separation, algae cultivation, and gas stripping. We first elucidate the mechanisms that contribute to bubble size reduction via OGS, followed by a comparative assessment of three technologies for generating oscillating airflow: solenoid valve, loudspeaker, and fluidic oscillator. Key factors influencing OGS performance, particularly oscillation frequency and amplitude, are discussed for their momentous role in producing smaller bubbles. Our findings demonstrate that OGS-generated microbubbles not only boost reaction efficiency and lower energy consumption but also reduce chemical usage and the footprint of treatment facilities. We conclude with insights and potential directions for advancing OGS technology, emphasizing that while enhancing gas-liquid mass transfer through OGS presents a promising approach, the development of stable oscillation-generating equipment is crucial for optimizing process performance.

Against the global backdrop of carbon neutrality, technological revolution, and deep oil development strategies, the advancement of large-scale integrated technologies for CO₂ geological utilization and sequestration (CO₂-GUS) holds strategic significance for safeguarding national energy security and mitigating climate change. Currently, century-scale geological sequestration and utilization of CO₂ remain heavily reliant on simulation and predictive methodologies, underscoring an urgent need to advance collaborative innovation between molecular design strategies and engineering application technologies. This paper focuses on recent progress in this field, systematically reviewing the design strategies of CO₂-responsive gels, self-adaptive foams, nano-bubbles, and supercritical CO₂ thickeners, with particular emphasis on molecular design principles for CO₂ affinity and deep subsurface adaptability. It analyzes the temperature and salt tolerance of CO₂-responsive gels and thickeners, as well as CO₂ mobility control mechanisms, reveals the synergistic mechanism of energy release enhancement and enhanced oil recovery (EOR) via CO₂ nano-bubble bursting, and clarifies the colloidal interfacial behavior of CO₂ self-adaptive foams. Furthermore, this study outlines future directions for advanced atomic force microscopy (AFM) characterization techniques at the molecular and atomic scales in CO₂-GUS applications. It also evaluates the engineering performance of these systems in synergistic CO₂-EOR and sequestration technologies, as well as in integrated CO₂ fracturing-EOR-sequestration processes. Finally, a century-scale deployment framework for CO₂ self-adaptive functional materials in geological utilization and sequestration is proposed, thereby providing a theoretical basis and technical support for the long-term safe management of CO₂.

Fluorescent molecularly imprinted polymers (FMIPs) have emerged as promising biomedical tools due to their high selectivity, stability, and tunable fluorescent properties. Their distinct combination of selective molecular recognition and sensitive optical signaling makes them appropriate for a variety of diagnostic and sensing applications especially for healthcare monitoring. This review summarizes recent advances in FMIPs synthesis strategies, focusing on innovative polymerization methods such as controlled/living radical polymerization and green synthesis approaches that address key challenges in reproducibility, scalability, and environmental sustainability. Advances in polymer design, functional monomer selection, and nanofabrication techniques have considerably increased FMIP sensitivity and specificity for critical biomolecular sensing applications. These smart materials contain extremely selective binding sites that resemble natural receptors, allowing for precise biomolecule detection in applications such as biosensing, bioimaging, and medication administration. The integration of modern fluorescence-based detection techniques improves their ability to monitor biological processes in real time with high precision. This comprehensive review also addresses the most challenges of FMIPs, such as largescale synthesis, biocompatibility, template removal and signal stability. Finally, future directions for developing FMIPs for personalized medicine and next-generation POC diagnostics are discussed.

Corrosion-induced material degradation in industrial systems necessitates the use of novel and efficient materials with multipurpose qualities for durable protection. The ability of conventional corrosion inhibitors for long-term, aqueous phase protection is negatively impacted by their tendency to be either hydrophilic (easy to solvate in polar electrolytes) or hydrophobic (insoluble). The special chemical, structural, and interfacial features of Janus materials have made them a promising class of effective alternatives with a dual-face asymmetry, meaning that one face is hydrophilic and the other is hydrophobic. This review features the collection of coordination and corrosion inhibition potential of Janus materials, including Janus graphene (G), graphene oxide (GO), Janus silica (Si) nanoparticles, Janus polymers, and their composites. These special materials offer efficient surface covering and protection by adsorbing horizontally at the metal-electrolyte interface. The tailored hydrophilic side of Janus materials faces the metal surface, while the hydrophobic side faces the solution side, deterring water and other corrosive species. Janus materials, especially their composites, can be considered as “complete corrosion inhibitor packets” as they not only provide real-time anticorrosion protection but also manifest the self-healing and self-reporting properties in different corrosive environments, including simulated body fluids (SBFs). They passivate the metal surface and provide a prolonged pathway for electrolyte and corrosive species diffusion through labyrinth effect. Their faces can be suitably tailored for better coordination, adsorption, and performance. This review offers insights into Janus materials synthesis for improved performance, highlighting both challenges and opportunities in corrosion protection.

Carbon capture and storage (CCS) offers the potential to remove and safely store significant quantities of carbon dioxide from the atmosphere, thereby limiting global warming. Conventional geological storage involves injecting CO2, in gaseous or supercritical state, into porous rock reservoirs, relying on geological top seals, capillary forces and/or dissolution in groundwater as the primary “locking-in” processes. An alternative method injects CO2-saturated water into mafic rocks (basalts), chemically inducing in-situ mineralization of CO2 to form solid carbonate minerals. This mechanism offers the lowest risk of carbon returning to the atmosphere. This review synthesizes field and laboratory studies on CO2 mineralization in basaltic rocks and the resulting impact on the rock’s pore network, permeability and porosity. Evidence indicates that dissolution-precipitation reactions substantially alter basalt microstructure, with outcomes strongly influenced by (i) sufficient fluid residence time within the pore space, (ii) adequate reactive surface area, including both total rock surface and reactive mineral phases, and (iii) in-situ permeability and porosity that enable efficient CO2-saturated water injection with minimal energy input. While dissolution enhances pore connectivity and injectivity, secondary carbonate precipitation can clog flow pathways, though fracture opening under pressure-temperature gradients may counteract these effects. Field-scale projects such as CarbFix demonstrate that continuous dissolved-CO2 injection promotes near-well dissolution while shifting carbonate precipitation farther from the injection site, reducing clogging risks. Current findings highlight basaltic formations as promising, safe, and scalable reservoirs for permanent CO2 storage, though further research is needed to quantify pore-scale processes and optimize injection strategies.

Mineral precipitation in porous media is an important process that controls the evolution of physical-chemical properties of many natural and engineered systems. This review aims to provide an overview of the status quo understandings of this process and a perspective on future research needs. We reviewed the fundamentals of the thermodynamic and kinetic theories of nucleation and crystal growth, and the key factors (e.g., substrate properties and pore sizes) that control mineral precipitation in porous media. In particular, we focused on how local reactive transport conditions dictate the extent and spatial distribution of mineral precipitates in flowing supersaturated solutions, mixing dominated systems, and coupled mineral dissolution and precipitation systems. Moreover, the review summarizes constitutive relations that have been used to model precipitation-driven alteration in bulk properties such as permeability, diffusivity and mineral reactivity, as well as their applicability and limitations. While there have been exciting developments in experimental and modeling efforts in improved understanding, some outstanding research questions require dedicated future investigations. They include more rigorous descriptions of emerging precipitation phenomena such as oscillatory zoning during the precipitation of solid solutions, considerations of the coupling between geochemical and geomechanical processes with precipitation induced cracking being a worthy example, and the upscaling of fine scale process and properties (e.g., confinement, multiphase flow dynamics) in to macroscopic predictive models. Overall, this review highlights the importance, advances and challenges of improved understanding of mineral precipitation in fractured porous media.

The rapid growth of electric vehicles, portable electronic devices, and stationary energy storage systems, coupled with the limited lifespan of lithium-ion batteries (LIBs), has led to a substantial increase in spent LIBs. In response to the urgent demand for resource recovery and environmental protection, the recycling of spent LIBs, particularly the separation of anode and cathode materials, which are the two most significant components, has become a critical area of research. Froth flotation offers a promising method by selectively separating particles based on differences in surface hydrophobicity, without altering the structure or chemical composition of the materials involved. The intrinsic hydrophobicity differences between anode and cathode materials (e.g., graphite and lithium metal oxides) make flotation an attractive technique for the recycling of spent LIBs. Hence, this review first outlines the fundamental principles of froth flotation, with particular emphasis on the roles of flotation agents—collectors, frothers, and dispersants—in modifying the surface hydrophobicity of various electrode materials. The interplay between flotation agents and the separation efficiency of anode and cathode components is examined in depth. However, several factors, such as the presence of organic binders and additives, residual lithium in the discharged anode, and surface degradation of electrode materials, may impede effective separation. Accordingly, this review further explores a range of pretreatment strategies designed to restore electrode surface properties and enhance flotation performance. This paper provides a comprehensive perspective of flotation-based separation in spent LIBs recycling, offering valuable insights and practical implications for advancing large-scale, efficient, and sustainable recovery technologies.

Langmuir-Blodgett (LB) technology excels in assembling nanomaterials into precise layered structures, yet challenges in solvent requirements and scalability limit its broader application. This review systematically analyzes recent advancements in LB methodologies—from solvent engineering to innovative transfer techniques—that enable the fabrication of complex architectures with enhanced optoelectronic, catalytic, and biomimetic properties for applications in sensing, energy storage, and interfacial science. We critically examine its dual role in improving intrinsic material performance and serving as a versatile platform for synthesizing functional systems. Looking forward, we outline key development paths, including heteroassembly, integration with non-equilibrium systems, and advanced biomimetic membranes. These directions, capitalizing on LB's core strengths in molecular-level precision and macroscopic force-directed nanoarchitectonics, are poised to drive innovations in next-generation nanomaterials and devices.
