Abstract :
Traditional nanofiltration membranes allow high rejection of low molecular weight organic matter, yet suffer from a low flux and a high operation pressure, and they pose an environmental concern because they are made of petroleum-based polymers. Herein, a novel environmentally friendly filter membrane for ultrafast molecular separation has been developed using natural and artificial biomaterials as building units. Cellulose micron fibers, a natural biopolymer, serve as a stable substrate for the growth of hydroxyapatite (HAP) nanowire bunches, which are the main inorganic components of bones and teeth. The vertically aligned HAP nanowire bunches provide abundant nanoscale surfaces and confinement space for the attachment of dopamine and subsequently self-polymerization into polydopamine (PDA) sub-micron particles, which are a melanin-like bioactive polymer. On the one hand, the as-built micro-nano hierarchical configuration enables ultrahigh permeance (>6000 L m(-2) h(-1) bar(-1)) through the filter membrane at a low pressure (62 mbar). On the other hand, molecular dynamics simulations reveal that synergy between multiple molecular interactions of HAP and PDA contributes to the universal separation of different organic pollutants from water (i.e., cationic and anionic dyes and antibiotics) at a high removal rate of > 97 %. Overall, this work ingeniously uses biocompatible biomaterials to build a hierarchical filter membrane, thereby enabling ultrafast and efficient molecular separation.

Abstract :
Heterojunction photocatalysts, which consist of two or more semiconductors, have garnered significant attention owing to their extensive benefits, including a broad-spectrum response, efficient carrier separation and migration, as well as robust redox capabilities. Among the myriad of semiconductors, graphitic carbon nitride (g-C3N4) and zinc indium sulfide (ZnIn2S4) have been extensively researched due to their low toxicity, straightforward and scalable synthesis processes, controllable microstructures, and exceptional chemical stability. Recently, there has been a trend towards integrating these two semiconductors to complement each other's strengths. Consequently, a systematic summary and outlook on g-C3N4/ZnIn2S4 heterojunction photocatalysts is both urgent and valuable. This review summarizes the advancements in the g-C3N4/ZnIn2S4 heterojunctions in the last 10 years. We first analyzed the charge-transfer mechanisms in the type-I, type-II, Z-scheme and S-scheme heterojunctions. Then the typical synthesis methods employed for creating g-C3N4/ZnIn2S4 heterojunctions are introduced. Subsequently, we delve into the regulation strategies for g-C3N4/ZnIn2S4 heterojunctions, including morphology optimization, heteroatom doping, defect engineering, and the construction of multinary composites. The design concept and superiorities of these strategies are thoroughly discussed. Following this, we systematically showcase the photocatalytic applications of g-C3N4/ZnIn2S4 heterojunctions, encompassing CO2 reduction, H2 evolution, pollutant degradation, H2O2 production, biomass conversion, photoelectrochemical sensors, and so forth. Last, we propose the challenges that lie ahead in future research endeavors. This comprehensive review is expected to provide an instructive guideline for rational design and applications of g-C3N4/ZnIn2S4 heterojunctions.

Abstract :
In this study, divalent calcium cation with large radius and trivalent yttrium cation with small radius were introduced to develop co-stabilized zirconia ceramics with both superior mechanical properties and aging resistance. Through a reverse coprecipitation-hydrothermal method, a series of ultrafine xCaO-yY2O3-ZrO2 (x = 2.0, 3.0, y = 0.5, 1.0, 1.5, 2.0) raw powders with high quality were fabricated for the production of nanostructured ceramics via low-temperature pressurelessly sintering. The sintering process was optimized by investigating the effects of sintering temperature on densification, grain growth and phase evolution. The minimally doped 2.0CaO-0.5Y2O3-ZrO2 ceramic retained pure tetragonal phase at room temperature, achieving a balance of excellent toughness and high aging resistance. The impacts of chemical composition on microstructure, hardness, toughness and aging resistance were examined for these xCaO-yY2O3-ZrO2 (x = 2.0, 3.0, y = 0.5, 1.0, 1.5, 2.0) ceramics. The segregation of calcium and yttrium cations at grain boundaries effectively tailored the microstructure. It was observed that substituting small trivalent yttrium cations for large divalent calcium cations effectively enhanced the aging resistance without sacrificing mechanical properties, due to the strengthened grain boundaries and asymmetrical distribution of cations among grains. This work not only produces low-doped zirconia ceramics with both excellent mechanical properties and aging resistance, but also presents straightforward method for preparation of high-quality raw powders and delicate microstructural engineering during sintering for developing advanced structural ceramics. © 2025 Elsevier Ltd and Techna Group S.r.l.

Abstract :
Bacterial infections result in significant burdens on public health, especially with the increasing prevalence of antibiotic resistance owing to the overuse of antibiotics. The development of the next-generation nanoantibacterial materials as alternatives to antibiotics is urgently needed. Metal-organic frameworks (MOFs) have been emerging as promising antibacterial materials. However, the impact of metal centers on the properties and antibacterial activity of MOFs has not been clarified to date. In this work, five M-MOF nanomaterials (M = Fe, Co, Ni, Cu, Zn) are synthesized with 2-methylimidazole as an organic ligand. Subsequently, the minimum inhibitory concentration (MIC), minimum bactericidal concentration, and time-kill curves are studied to evaluate their antibacterial activity. In addition, the destruction of the bacterial cells after treatment with M-MOFs is observed via scanning electron microscopy. The experimental results demonstrate that the Co-MOF and Zn-MOF polyhedra exhibit optimal antibacterial activity. They can effectively inhibit the growth of both Gram-negative bacteria Escherichia coli and Gram-positive bacteria Staphylococcus aureus at a low concentration. On the other hand, the Fe-MOF irregular particles show the weakest antibacterial activity among five M-MOFs and the antibacterial activity of the Ni-MOF and Cu-MOF nanosheets are comparable to each other. The huge difference in antibacterial activity of M-MOFs is attributed to the difference in the shape and size, specific surface area, surface charge, ion release, and production of reactive oxygen species. Overall, this study clarifies the relationship between metal centers in M-MOFs and their antibacterial activity.

Abstract :
Two-dimension nanosheets are ideal photocatalysts for CO2 reduction due to their high exposure of active sites and short charge transfer pathway. However, 2D photocatalysts have a tendency to agglomeration, thus compromising the performance of photocatalytic CO2 reduction. Trees, one of the most important plants for photosynthesis, have a unique "leaf-on-branch" structure. This unique two-dimension/one-dimension (2D/1D) configuration maximizes the adsorption of CO2 molecules and light harvesting. Herein, a tree-inspired semiconductor-on-ceramic 2D/1D heterostructure for efficient photocatalytic CO2 reduction is reported. The cobalt silicate (CoSi) nanosheets (similar to 0.68 nm) are in situ grown on the surfaces of hydroxyapatite (HAP) nanowires, creating a well-defined 2D/1D hierarchical structure. The vertical alignment of ultrathin CoSi nanosheets on the HAP nanowires effectively suppresses their agglomeration, leading to a large BET surface area (106.45 m(2)/g) and excellent CO2 adsorption (8.00 cm(3) g(-1)). The results of photoelectrochemical characterization demonstrate that the 2D/1D hierarchical structure is powerful to expedite charge transfer. As a result, the gas generation rate of CO is as high as 28780 mu mol g(-1) h(-1) over the CoSi-on-HAP 2D/1D heterostructure. In addition, the electron transfer mechanism and reaction pathways of CO2 reduction are revealed by in situ irradiated XPS and in situ DRIFT spectra.

Abstract :
Regulating charge transfer and reaction pathways are effective strategies for boosting photocatalytic CO2 reduction. Herein, Co3O4/ZrO2 mesoporous octahedrons are synthesized through facile pyrolysis of UIO-66@ZIF-67 core/shell octahedrons. The as-obtained Co3O4/ZrO2 mesoporous octahedrons are assembled by highly dispersive and small-sized nanoparticles, with 13 nm average particle size and 5.8 nm pore width, leading to a high specific surface area of 43.11 m(2) g(-1). Benefiting from active-site engineering, the charge-transfer kinetics and CO2 adsorption are successfully enhanced. In addition, density functional theory calculations reveal that ZrO2 tailors the reaction pathway of CO2 reduction by promoting CO2 activation to *CO2 and intermediate formation (*COOH and *CO), as well as decreasing the energy barrier of the rate-limiting step (*CO -> CO). Thus, the Co3O4/ZrO2 mesoporous octahedrons afford a turnover frequency of 28.82 h(-1), 16.95-fold larger than pure Co3O4.

Abstract :
Beyond traditional paper, multifunctional nanopaper has received much attention in recent years. Currently, many nanomaterials have been successfully used as building units of nanopaper. However, it remains a great challenge to prepare flexible and freestanding metal-organic framework (MOF) nanopaper owing to the low aspect ratio and brittleness of MOF nanocrystals. Herein, this work develops a flexible and free-standing MOF nanopaper with MOF nanowires as building units. The manganese-based MOF (Mn-MOF) nanowires with lengths up to 100 mu m are synthesized by a facile solvothermal method. Through a paper-making technique, the Mn-MOF nanowires interweave with each other to form a three-dimensional architecture, thus creating a flexible and free-standing Mn-MOF nanowire paper. Furthermore, the surface properties can be engineered to obtain high hydrophobicity by modifying polydimethylsiloxane (PDMS) on the surfaces of the Mn-MOF nanowire paper. The water contact angle reaches 130 degrees. As a proof of concept, this work presents two potential applications of the Mn-MOF/PDMS nanowire paper: (i) The as-prepared Mn-MOF/PDMS nanowire paper is compatible with a commercial printer. The as-printed colorful patterns are of high quality, and (ii) benefiting from the highly hydrophobic surfaces, the Mn-MOF/PDMS nanowire paper is able to efficiently separate oil from water.

Abstract :
Developing efficient and robust artificial hydrogenases with sophisticated structure as catalysts is potential for practical solar hydrogen application, withstanding challenges proposed by oxygen generated in situ by water splitting. Based on Pearson's hard/soft acid/base (HSAB) theory and compartmental ligand strategy, we prepared a 3D heterometallic MOF, [Ni3Pr2(6-mna)6(H2O)4]center dot(H2O)5 (1) (6-mna = 6-mercaptonicotinate divalent anion), with alternately arranged redox-active NiS cluster-based nodes and redox-inactive PrO cluster-based nodes to mimic simultaneously both the active center and the surrounding polypeptide microenvironment in natural hydrogenase. Despite numerous negative effects caused by oxygen, with the sophisticated structure, 1 achieved both enhanced stability and efficient hydrogen producing activity of 40.3 mmol/g in air atmosphere. The influence of oxygen on photocatalytic hydrogen production was investigated by contrasting mechanisms of both photo-induced electron transferring step and chemical catalyzing step under aerobic and anerobic conditions. The reductive mechanism is promoted under anerobic conditions, whereas oxidative mechanism is favored in aerobic conditions due to the suppressed production of radical intermediate Fl3-center dot in the presence of oxygen, as evidenced by in-situ electron spin resonance spectroscopy and in-situ ultraviolet-visible absorption spectrum. This paper presents a simple method for MOFs to closely simulate both the active center and surrounding protein of biological enzymes, and offers a new pathway for developing stable and efficient catalyst for solar hydrogen production.

Abstract :
The 3-level features of Latent fingerprints (LFPs) are pivotal in linking suspects with problematic or incomplete fingerprint data, constituting one of the most robust forms of evidence. Aggregation-induced emission (AIE) materials, known for their heightened emissive properties in high aggregation states, provide a robust and powerful approach for developing techniques for 3-level details of LFPs. So far, tremendous efforts have been devoted to solving high background fluorescence interference during the 3-level LFPs visualization process. This review commences with an overview of 3-level features and summarizes the interaction and mechanism of visualizing LFPs involving AIE materials and LFPs secretions. Moreover, it encompasses strategies to enhance the contrast and brightness of 3-level LFPs images. We highlight the mechanism of AIE ' s physicochemical properties and their effects on the visualization of 3-level LFPs. Additionally, we provide insights into potential challenges and opportunities in this emerging field. This paper summarizes the recent development regarding AIE materials for 3-level LFPs visualization, focusing on the visualizing mechanism, engineering strategies, and structure-function relationship. Meanwhile, this review also investigates present challenges and the future directions of AIE materials in this booming research field. image
