Significant advancements have been made in the field, with the goal of producing functional materials from these nanoscale components. 2D nanomaterials, in particular, have gained substantial attention due to their large surface areas which are ideal for numerous surface-active applications. In this review article, nanoarchitectonics of 2D nanomaterials based biomedical applications are discussed. We aim to provide a concise overview of how nanoarchitectonics using 2D nanomaterials can be applied to dental healthcare, with an emphasis on biosensing and drug delivery. By offering a deeper understanding of nanoarchitectonics with programmable structures and predictable properties, we hope to inspire new innovations in the dental bioapplications of 2D nanomaterials.

Pickering-polymerized high internal phase emulsions have attracted attention since their successful first preparation 15 years ago, primarily due to their large pores and potential for functionalization during production. This review elucidates the fundamental principles of Pickering emulsions, Pickering HIPEs, and Pickering PolyHIPEs while comparing them to conventional surfactant-stabilized counterparts. The morphology of Pickering PolyHIPEs, with particular emphasis on methods for achieving interconnected structures, is explored and critically assessed. Lastly, the mechanical properties and diverse applications of these materials are reviewed, highlighting their use as catalytic supports and sorbent materials. The study aims to guide both new and experienced researchers in the field by comprehensively addressing the current potential and challenges of Pickering PolyHIPEs. Once the mystery behind the closed cellular pores of Pickering PolyHIPEs is resolved, these materials are expected to become more popular, particularly in applications where mass transfer is critical, such as tissue engineering.

Cell-cell junctions are essential for maintaining tissue integrity and regulating a wide range of physiological processes. While the disruption of intercellular junctions may lead to pathological conditions, it also presents an opportunity for therapeutic interventions.

In this review, we provide a comprehensive overview of the various nanomaterials interaction with cell-cell junctions. We discussed their underlying mechanisms, heterogenous effects on cellular behavior, and the therapeutic strategies of applying nanomaterial-induced intercellular junction disruption.

Oil spills have long-lasting and harmful impacts on the environment, particularly on aquatic ecosystems. This review provides a comprehensive overview of conventional methods for oil spill removal, highlighting both their advantages and limitations. Traditional methods for addressing oil spills, including physical, thermal, biological and chemical techniques, often prove insufficient, with chemical dispersants being the most popular approach. However, the concern about the toxicity and low biodegradability of these dispersants have led researchers to explore more effective and ecologically benign alternatives. Recently, surface-active ionic liquids (SAILs) have gained interest due to their amphiphilic nature, green and biodegradable characteristics, and excellent performance under various temperature and salinity conditions. In this review, the molecular composition of SAILs, with a specific emphasis on the roles of their head groups, alkyl chains, and counter anions, has been discussed. Additionally, the aggregation behavior of SAILs, their ability to reduce interfacial tension (IFT), and their potential to form stable emulsions, which are important for effective oil dispersion, has been also discussed in the paper. This review also examines key environmental factors such as temperature and salinity that influence the efficacy of oil dispersion using SAILs. The study investigates the possibilities of SAILs as an environmentally friendly substitute for conventional dispersants, while also discussing the challenges and possible future paths for the industry. However, the long-term environmental effects of SAILs and their degradation products are still uncertain, underscoring the necessity of future research. Insights into the optimization of SAIL formulations, their environmental impact, and the feasibility of large-scale application are also discussed, offering a forward-looking perspective on the development of next-generation oil spill remediation technologies.

In the past decade, graphene-based nanomaterials (GBNs) have been considerably investigated in agriculture due to their exceptionally enriched physicochemical properties. Productivity in the agricultural sector relies significantly on agrochemicals. However, conventional systems suffer from a lack of application efficiency, resulting in environmental pollution and associated problems. Due to high surface area, easy functionalization, high chemical stability, biocompatibility, and ability to adhere to biological structures, GBNs become a promising candidate for agro-delivery carriers. A comprehensive review on developments of GBNs for pesticide delivery, nutrient delivery, food packaging and preservation, and their impacts on plant growth and development are missing in the literature. To address this, here we presented a detailed review on the material design, agrochemicals loading, release or diffusion kinetics, in-vivo applications, and effects of GBNs on plants. The GBNs found to improve the efficacy of existing agrochemicals and food preservatives, aiming to decrease the overall burden of these substances. The incorporation of GBNs in biocompatible and biodegradable polymers is reported to improve their oxygen barrier and mechanical properties for food packaging applications, targeting to reduce the use of petroleum-derived polymers based current food packaging materials, which leads to serious environmental impacts. In the context of plant nanobionics, GBNs has been found to boost the plant growth at low concentrations. Here, recommendations for future research have been deliberated, drawing reference from the relevant area to gain a deeper understanding of the underlying science, and to develop better delivery and packaging applications approaches. Additionally, discussions on recommendations regarding the safe concentration of GBNs for plant nanobionics are presented to facilitate their secure and effective utilization.

With the development of new and clean energy (offshore wind power, fuel cells, aqueous zinc ion batteries, lithium-ion batteries, etc.), the corrosion and security problems in special environments of the new energy system have attracted much attention. Corrosion protection on the metals applied in new energy system can reduce the economic loss, security risk, and energy consumption, as well as guarantee the efficiency of energy system. Traditional coatings face challenges in agglomeration of nano fillers, structural control, environmental issues, and poor conductivity, which limits the applications. With features in controllable surface chemistry and composition, rich surface terminations, better conductivity than graphene oxide, high aspect-ratio, strong impermeability, and low friction coefficient, the two-dimensional (2D) MXene presents potential for applications in corrosion protection in new energy systems. Despite progress has been made in the MXene for corrosion protection, there is still a lack of comprehensive review regarding the design and mechanisms of anti-corrosive MXene-based materials for corrosion protection in new energy system. In this review, a brief induction of MXene and the specially four corrosive environments (offshore wind power at deep sea, bipolar plates in PEMFC environments, zinc anode in AZIBs, and current collectors in Li-ion battery) are presented. Importantly, the design strategies and mechanisms of the MXene-based anti-corrosive coatings on metals used in the special environments are discussed in detail. Finally, the challenges and research trends in the MXene-based coatings for new energy systems are prospected. This review provides further understanding of corrosion in new energy and would expand the application prospects of MXene.

Colloidal cellulose nanoparticles, or nanocelluloses, are derived from natural cellulose sources in a top-down manner via physical and/or chemical treatments that extract naturally occurring cellulose nanostructures. Naturally derived nanocelluloses have been successfully commercialized in various fields, and their potential is still being widely explored in materials science. Moreover, recent advances in nanoarchitectonics of low-molecular-weight cellulose, or cello-oligosaccharides, have opened new avenues for developing "artificial nanocelluloses". Artificial nanocelluloses composed of cello-oligosaccharides synthesized via enzymatic oligomerization or solid-phase glycan synthesis technology are termed "synthetic nanocelluloses". These nanostructures are abiotically constructed in a bottom-up manner at the molecular level via self-assembly of cello-oligosaccharides in vitro. Modulation of the assembly process and molecular design provides control over the molecular alignment, nanomorphology, and surface functionality of artificial nanocelluloses. This review summarizes recent research progress in artificial nanocelluloses, from the preparation and self-assembly of cello-oligosaccharides to their potential applications.

Water treatment procedures are increasingly utilized for resource recovery and wastewater disinfection, addressing the current challenges of clean water depletion and wastewater management. Various pollutants, including dyes, acids, pharmaceuticals, and toxic heavy metals have been released into the environment through industrial, domestic, and agricultural activities, posing serious environmental and public health risks. Addressing these issues requires the development of more effective waste treatment processes. Membrane-based treatment technologies offer significant advantages, including high efficiency, versatility, and cost-effectiveness, making them a promising solution for mitigating the impact of these pollutants. In view of this, the potential of ion exchange membranes (IEMs) is continuously increasing due to their advanced characteristics compared to conventional techniques. Anion exchange membranes (AEMs), a special class of IEMs, selectively allow anions to pass through their pores due to the positive charge on their surface. This selective passage aids in resource recovery and removing specific types of pollutants. This review covers preparation methods, modification techniques, and classification of AEMs. It offers a practical classification based on the method of synthesis and structural properties of AEMs. The water-based applications of AEMs including, electrodialysis, diffusion dialysis, and electro-electrodialysis for various wastewater treatments such as heavy metal recovery, dye removal, pharmaceutical removal, and acid separation, have been discussed in detail. Additionally, the effect of various operational parameters on the performance and SWOT (strengths, weaknesses, opportunities, and threats) analysis of AEMs in effluent treatment are presented. The review provides detailed insights into the current status, challenges, and future directions of AEM-based technologies, offering suggestions for future advancements.

Pickering emulsions (PEs) are dispersions stabilized by solid particles, which are derived from various materials, both organic (proteins, polysaccharides, lipids) and inorganic (metals, silica, metal oxides). These colloidal particles play a critical role in ensuring the stability and functionality of PEs, making them highly valued across multiple industries due to their enhanced stability and lower toxicity compared to conventional emulsions. The stabilization mechanisms in PEs differ from those in emulsions stabilized by surfactants or biopolymers. The stability of PEs is influenced by intrinsic particle properties, such as wettability, size, shape, deformability, and charge, as well as external conditions like pH, salinity, and temperature. Some particles, especially organic ones, alone may not be effective stabilizers. For instance, many polysaccharides inherently lack surface activity, while most proteins have significant surface activity but often become unstable under environmental stresses, potentially leading to emulsion instability. The chemical composition and morphology of the particles can lead to varying properties, particularly wettability, which plays a vital role in their ability to adsorb at interfaces. As a result, surface modification emerges as an essential approach for improving the effectiveness of particles as stabilizers in PEs. This review presents the mechanisms that stabilize PEs, identifies factors influencing the stability of PEs, and discusses physical and chemical techniques for modifying particle surfaces. There has been a significant advance in understanding surface modification, employing both physical (non-covalent bonds) and chemical (covalent bonds) approaches. These insights are invaluable for optimizing PE formulations, broadening their application potential across various fields.

Droplets impacting solid surfaces are encountered in nature and industry, from rain to agricultural spraying and inkjet printing. Surfactants are an important factor that affects the impact behavior of droplets. An in-depth knowledge of the influence and mechanisms of surfactants on the dynamics of droplet impact can enhance the precise control of droplets in industrial processes. Herein, recent insights into surfactant-enhanced droplet deposition on hydrophobic surfaces are reviewed. First, the mechanisms of surfactant-enhanced droplet deposition are summarized. Second, the factors that influence droplet deposition, such as molecular diffusion, convective diffusion of surfactants, characteristics of hydrophobic surfaces, and interaction between the surfactant-laden droplets and the hydrophobic surfaces, are explored. Additionally, the influences of surfactants on the spreading and retraction processes of impacting droplets, maximum spreading factor, and oscillation dynamics are reviewed. Finally, typical applications of surfactants in different fields, such as inkjet printing, supercooled surface, and agricultural spray, are summarized, along with challenges and prospects in future research, to provide suggestions for subsequent studies.
