With the flourishing of mussel-inspired chemistry, the fast-growing development for environmentally friendly materials, and the need for inexpensive and biocompatible analogues to PDA in gel design, TA has led to its gradual emergence as a research focus due to its remarkable biocompatible, renewable, sustainable and particular physicochemical properties. As a natural building block, TA can be used as a substrate or crosslinker, ensuring versatile functional polymeric networks for various applications. In this review, the design of TA-based gels is summarized in detail (i.e., different interactions such as: metal coordination, electrostatic, hydrophobic, host–guest, cation-π and π-π stacking interactions, hydrogen bonding and various reactions including: phenol–amine Michael and Schiff base, phenol–thiol Michael addition, phenol–epoxy ring opening reaction, etc.). Subsequently, TA-based gels with a variety of functionalities, including mechanical, adhesion, conductive, self-healing, UV-shielding, anti-swelling, anti-freezing, shape memory, antioxidant, antibacterial, anti-inflammatory and responsive properties are introduced in detail. Then, a summary of recent developments in the use of TA-based gels is provided, including bioelectronics, biomedicine, energy, packaging, water treatment and other fields. Finally, the difficulties that TA-based gels are currently facing are outlined, and an original yet realistic viewpoint is provided in an effort to spur future development.

Fossil-based polymers continue to dominate the market for single-use food packaging, despite increasing concerns about their sustainability. In response, natural and renewable polymers, such as proteins and polysaccharides, are gaining attention as potential alternatives due to their biodegradability and biocompatibility. However, their broader adoption is hindered by the need to improve their mechanical, barrier, and thermal properties. Tannic acid (TA) has emerged as a particularly effective additive for biopolymer-based films, offering strong antioxidant and antimicrobial properties. It also enhances mechanical and barrier characteristics through physical and/or covalent crosslinking. As a result, TA shows great potential as an additive for bioplastics, improving food packaging performance and extending product shelf life, while benefiting both the environment and the food industry. Despite the promising applications of TA, comprehensive reviews that focus on recent developments in its performance and bioactive properties remain limited. This review aims to highlight the effectiveness of TA as both an active ingredient and a crosslinking agent in various biopolymer films, offering valuable insights into its role in sustainable food packaging solutions by critically examining the latest advancements.

Interfacial electrostatic charges are a universal phenomenon in nature. In recent years, interest in the chemical reactivity of electrostatic charges has grown. Interfacial electrostatic charge-driven chemical synthesis reduces the reliance on redox reagents, catalysts, and hazardous solvents, which promotes environmental sustainability and cost-effectiveness in the chemical industry. Electrostatic charges can be generated at the interfaces between solids, liquids, and gases. The chemical properties of electrostatic charges have been observed at interfaces between solids and liquids, and between liquids and gases. This review summarized the chemical reactivity of interfacial electrostatic charges and its mechanisms. Electrostatic charges play a fundamental role in providing electrons and creating electric fields, which in turn induce charge transfer, radical formation, and molecular orientation. We classified the role of interfacial charges in chemical reactions and provided new perspectives. Interfacial electrostatic charges can be generated with mechanical energy input, a power supply and interface transition from solid-liquid to liquid-gas. Redox and catalytic reactions involving inorganic, organic compounds and biomolecules are driven by interfacial electrostatic charges. Electrostatic chemistry mechanisms are currently a subject of debate because there is insufficient experimental evidence. Challenges and opportunities associated with interfacial electrostatic chemistry are discussed. Knowledge of the reactivity of interfacial electrostatic charges could be used to understand electrostatic phenomena in nature, advance green chemistry, and even study the origins of life. We expect this emerging topic will appeal to scientists in disciplines including interfacial chemistry and electrostatics.

A comprehensive review of the rheology and related phenomena of high internal phase ratio emulsions (referred to as HIPREs) and foams is presented. Emulsions and foams with Brownian and non-Brownian inclusions (droplets/bubbles) are considered. The topics covered are osmotic pressure, modelling and experiments of the rheology of HIPREs/foams, time-dependent rheology (thixotropy/rheopexy), normal stresses, shear banding and slip effects in flow of HIPREs/foams, influence of solid particle stabilizers (Pickering emulsion/foam), and finally pipe rheology and flow of HIPREs/foams. This is the first review article that covers all aspects of the rheology of HIPREs/foams. The theoretical and empirical models describing the osmotic pressure and rheology (yield stress, storage modulus, viscosity, etc.) of HIPREs/foams are presented and their limitations pointed out. The contributions of entropic effects in the rheology of HIPREs/foams consisting of Brownian inclusions (droplets/bubbles) are given special consideration. The key experimental studies available in the literature are reviewed including measurements of yield stress, storage modulus, and viscosity of HIPREs/foams. Comparisons of experimental data with the theoretical and semi-theoretical models are made and the limitations of the models are identified. Experimental studies elaborating special effects in HIPREs/foams rheology such as thixotropy, rheopexy, normal stresses in fixed shear strain and steady shear, shear banding in thixotropic HIPREs/foams, and slip effects are also reviewed. The effects of average size and size distribution of inclusions (droplets/bubbles) on the rheology of HIPREs/foams are evaluated. The rheology of Pickering HIPREs/foams stabilized with solid nanoparticles at the interface is reviewed and compared with the rheology of surfactant-stabilized systems. Finally, the experimental work published on the pipe flow of HIPREs/foams and its connection to rheology is presented and discussed. The gaps in the existing knowledge of the rheology of HIPREs/foams are identified and future research directions in the area are given.

Covalent Organic Frameworks (COFs) are characterized by high thermochemical stability, low backbone density, well-controlled physical and chemical properties, large specific surface volume and porosity, permanently open pore structure, and various synthesis strategies. These remarkable attributes confer COFs with significant potential for a myriad of applications ranging from catalysis technology, gas separation and storage, optoelectronic materials, environmental and energy sciences, and biomedical development. There are many synthetic design methods for COF materials, and dynamic covalent chemistry is the scientific basis of COF materials-oriented design, which gives the error correction ability of the covalent assembly process, and is the key to obtaining crystallization and stability at the same time. However, “crystallinity” and “stability” in the synthesis and preparation of COF materials are often like “You can't have your cake and eat it, too”: on the one hand, the reversible covalent bonds used in the synthesis of highly crystalline COF framework are easy to decompose under extreme conditions, which greatly limits its application scenarios; On the other hand, although highly stable COF materials can be prepared by using irreversible covalent bonds, it is usually poor crystalline and difficult to have high performance. In addition, the strict deoxygenation operation required for synthesizing COF materials also limits its macro preparation and large-scale application. Therefore, the synthesis strategy and efficient preparation of highly stable and crystalline COF materials are a major obstacle to the practical application of this field. This paper describes the four structures of COF materials, as well as their synthesis methods, electrical energy-storing electrocatalysis, and significant environmental protection applications. The future directions, prospects, and possible barriers to the development of these materials are envisioned in.

The increasing atmospheric CO₂ levels and the urgent need for sustainable energy solutions have driven research into electrochemical CO₂ reduction. Carbon-based materials have received significant attention for their potential as electrocatalysts, yet their inert nature often limits their performance. Defect engineering and heteroatom doping have emerged as transformative approaches to overcome these limitations, enhancing both catalytic activity and Faradaic efficiency. This review systematically examines the role of these strategies across diverse carbon materials, including graphene, carbon nanotubes, carbon dots, and boron-doped diamond. Special attention is given to the incorporation of heteroatoms, such as nitrogen and boron, and the modulation of defect structures to optimize CO₂ reduction pathways. By exploring the interplay between dopant type, defect density, and material dimensionality, we provide a comprehensive understanding of how tailored carbon-based electrocatalysts can drive advancements in sustainable electrochemical CO₂ conversion. This work underscores the potential of defect-engineered and doped carbon materials to revolutionize the field of electrocatalysis, paving the way for innovative solutions to environmental and energy challenges.

The concept of nanoarchitectonics has emerged as a post-nanotechnology paradigm in the field of functional materials development. This concept entails the construction of functional material systems at the nanoscale, based on the knowledge acquired from nanotechnology. In biological systems, advanced nanoarchitectonics is achieved through precise structural organization governed by spatial localization, a process facilitated by localized assembly mechanisms. A thorough understanding of the principles of localized assembly is crucial for the creation of complex, asymmetric, hierarchical organizations that are similar in structure and function to living organisms. This review explores the concept of localized assembly, highlighting its biological inspiration, providing representative examples, and discussing its contributions to nanoarchitectonics. Key examples include assemblies using biological materials, those mimicking cellular functions, and those occurring within cells. Additionally, the role of interfacial interactions and liquid-liquid phase separation in localized assembly is emphasized. Particularly, the utilization of liquid-liquid phase separation demonstrates a remarkable capacity for forming intricate compartmentalized structures without discernible membranes, paving the way for multifunctional, localized systems. These localized assemblies are fundamental to essential biological functions and provide valuable insights into the molecular mechanisms underlying the origin of cells and life. Such understanding holds significant promise for advancing materials nanoarchitectonics, particularly in biomedical applications.

Food packaging (FP) plays a crucial role in maintaining food quality, and the integrity of FP is directly linked to its barrier properties, which ultimately affects the preservation ability of FP materials. Therefore, incorporation of self-healing (SH) properties has emerged as an intriguing approach to enhance the performance of FP materials. Materials possessing SH properties can sustain their integrity through dynamic covalent bonds and/or non-covalent interactions, thereby continuously preserving the barrier properties of FP materials. In this study, our focus lies in exploring SH materials for FP films/coatings. We provide a summary of the mechanisms underlying biopolymeric SH materials, discuss the preparation methods for biopolymeric SH FP films/coatings, and present the latest advancements in their application for food preservation. Finally, we outline the future opportunities and challenges associated with the application of SH materials in FP.

This review discusses and compares different measurement techniques for liquid foam flow experiments. Particular emphasis is put on measurements of foam velocity and liquid fraction. Because foam is opaque, complex and fragile, many of the established tools of fluid mechanics are not directly applicable. Consequently, these techniques had to be adapted or new approaches had to be developed. This review elucidates the most common techniques and approaches based on optical imaging, electrical conductivity, X-ray and neutron imaging, ultrasound, magnetic resonance imaging, positron emission tomography, and small-angle neutron scattering. Each technique has its specific advantages and limitations, and needs to be chosen wisely depending on the measurement requirements. To that end, this review provides some guidelines to choose the most appropriate technique for a specific measurement.
