Aqueous zinc metal batteries (AZMBs) have garnered significant attention owing to the inherent safety of aqueous electrolytes and the zinc anode's high theoretical specific capacity (820 mA h g−1). However, interfacial instability arising from rampant zinc dendrite growth and parasitic side reactions at the electrolyte/anode interface critically hinders practical implementation. Herein, we report an in situ solid electrolyte interphase (SEI) engineering strategy via frustrated Lewis pair (FLP)-mediated polymerization of 2-acrylamido-2-methylpropane sulfonic acid (AMPS), where FLP catalysis is achieved through synergistic interactions between metallic zinc and Zn2+ cations at the electrolyte/anode interface. In contrast to conventional electrolyte additives that rely on physical adsorption or chemical passivation, the polymerized AMPS (PAMPS) establishes a dual-functional interface: (i) rapid Zn2+ ion transport channels through sulfonic acid groups, and (ii) robust chemical bonding with zinc via acrylamide moieties. This unique architecture enables simultaneous regulation of Zn2+ flux homogeneity and interfacial stabilization. Accordingly, Zn‖Zn symmetric cells with the AMPS-containing electrolyte show stable cycling for 6500 h at 1 mA cm−2. Notably, under extreme conditions (10 mA cm−2, 10 mA h cm−2), the PAMPS-enabled anode achieves a coulombic efficiency of 99.7% and an unprecedented cumulative areal capacity of 12 A h cm−2—a fourfold improvement over state-of-the-art benchmarks. Additionally, the MnO2‖Zn full cells with the AMPS-containing electrolyte exhibit a high specific capacity of 300 mA h g−1 at 500 mA g−1 and long cycling stability of 10 000 cycles at 1.58 A g−1. This work offers a facile, economical and effective approach for designing a high-performance aqueous zinc metal battery for practical applications.

Immune checkpoint blockade (ICB) therapy faces major challenges including low clinical response rates, while traditional chemodynamic therapy (CDT) is highly dependent on intratumoral hydrogen peroxide (H₂O₂) levels. To address these limitations, we constructed a pH-responsive hyaluronic acid (HA)-based nanosystem (HA-Fc@ART) for targeted cancer therapy. This nanoplatform achieves tumor-specific delivery through the specific interaction between HA and CD44 receptors overexpressed on tumor cells. Upon accumulation in the acidic tumor microenvironment (TME), the nanosystem undergoes Schiff base bond hydrolysis to precisely release artemisinin (ART) and ferrocene (Fc), avoiding off-target toxicity. Fc catalyzes the cleavage of the endoperoxide bridge in ART to generate singlet oxygen ( 1 O₂) in an H₂O₂-independent manner. It simultaneously converts endogenous H₂O₂ into hydroxyl radicals (•OH) via the Fenton reaction. These dual pathways synergistically induce a reactive oxygen species (ROS) burst that efficiently eliminates cancer cells. Notably, HA-Fc@ART exhibits a high photothermal conversion efficiency of 35 ± 3%. The photothermal effect accelerates ROS production, and Fe(III) generated during the reaction depletes intracellular glutathione (GSH) to amplify oxidative damage. In vitro and in vivo experiments demonstrated that HA-Fc@ART possesses strong tumor-targeting ability. It effectively induces tumor immunogenic cell death (ICD) by releasing damage-associated molecular patterns (DAMPs). This process activates dendritic cell (DC) maturation, promotes macrophage M1 polarization, and enhances T cell infiltration into the TME. In the 4 T1 bilateral tumor model, the combination of HA-Fc@ART with photothermal therapy and anti-PD-L1 (αPD-L1) achieved complete ablation of primary tumors and significant inhibition of distant metastatic tumors. Histological analysis and hemolysis tests confirmed the nanosystem's excellent biosafety profile. This study provides a novel and efficient platform for improving the response rate of ICB therapy, offering new insights into the treatment of metastatic cancers.

Ara h 3, a prevalent peanut allergy, presents a considerable risk to public health. Preventing exposure to food allergens is the paramount method for safeguarding those with allergies. Consequently, we devised a polydopamine (PDA)-modulated gold self-coupling technique to fabricate plasmonic blackbodies (AuNBs@PDA) featuring multibranched configurations. High-performance SERS labels are possible using AuNBs@PDA's PDA coating and multi-branched design. It detects Ara h 3 ultra-sensitively in lateral flow immunochromatographic test strips (LFIA). SERS-LFIA has outstanding specificity, stability, and reproducibility, with a test strip shelf life of over a year and a LOD of 72.2 pg/mL, 295 times higher than standard AuNPs-LFIA. Implementing this technology accurately detects food samples. This sensitive and reliable platform for Ara h 3 detection has great potential for food allergy monitoring.

J- and H-aggregates of zinc tetraphenylporphyrin (ZnTPP) on carbon nanotube films (CNTFs) were prepared using the mixed solvent method. This resulted in completely different structures, such as the four-leaf clover and flower, on the CNTF, which were observed by recording SEM images. Characteristic changes in the electronic spectra of the ZnTPP monomer appeared when it underwent J- and H-aggregation. The measured photocurrent significantly varied for the same molecule when it was aggregated in two different ways on ITO and ITO/CNTF. The electron recombination resistance of the two aggregates, which was investigated using electrochemical impedance spectroscopy, was also different. The photocatalytic efficiency of the J- and H-aggregates was examined by performing methylene blue dye decoloration studies. In addition, a scanning electrochemical microscope was used to investigate the photoinduced charge transfer kinetics of the J- and H-aggregates at the electrode/electrolyte interface as a fresh attempt. The heterogeneous charge transfer constants for the J- and H-aggregates in the presence of light at varied intensities were calculated. Thereby, striking differences in the photophysical, photocatalytic, and photoelectrochemical properties of the J- and H-aggregates were visualized throughout our studies.

Glass/Glass-ceramic sealing is always accompanied by issues of high porosity and brittle joints. To migrate these problems, an Ag foam was innovatively induced as an interlayer in the process of glass sealing the yttria-stabilized zirconia (YSZ) ceramic to Mn–Co spinel-coated Crofer 22 H stainless steel. Interlayer-added joints showed a significant reduction in porosity, and the shear strength was improved to 52.3 MPa, with an enhancement of 37.8 %. The influence of interlayer on the microstructure of the joint has been investigated and the formation process of the joint is illustrated. The Ag interlayer expels gases from the sealant material through expansion at high temperatures and promotes finer nucleation grains of crystallites integrating with the interlayer, reducing the porosity and alleviating the brittleness as well.

A graphene-wrapped polyaniline nanoparticles film embedded in carbon cloth (CC/PANI/G) was fabricated and used as a 3D anodic electrocatalyst for oxidation of toluene methyl C−H groups. The methyl C−H bonds can be oxidized effectively at the CC/PANI/G anode with 99.9 % toluene conversion at a low applied voltage of only 1.0 V, which implies low energy input. Importantly, 86.6 % of toluene methyl C−H groups were converted to benzoyl groups (C=O), and hydrogen was produced efficiently at the cathode. The electrocatalytic efficiency at the CC/PANI/G anode was higher at lower voltage (1.0 V) than at higher voltage (1.5 V), and more hydrogen was produced at the corresponding cathode. The synergistic effect between the dynamic redox chemistry of nanoPANI and the excellent conductivity and anticorrosive action of graphene determined the high electrocatalytic efficiency of the oxidation of toluene methyl C−H groups at the CC/PANI/G anode. Owing to the chemical bonding between graphene and PANI, the anticorrosive CC/PANI/G anodic electrocatalyst was durable and effective for oxidation of toluene methyl C−H groups in acidic environment. This approach provides advanced electrode materials for transforming stable chemical bonds (C−H) into useful functional groups (C=O), which will be beneficial for the synthesis of organic intermediates with coupled hydrogen production. Graphical It's a wrap : A graphene-wrapped polyaniline nanoparticles film embedded in carbon cloth was fabricated and used as an anodic electrocatalyst for oxidation of toluene methyl C−H groups (see figure). A toluene conversion of 99.9 % at a low applied voltage of only 1.0 V with 86.6 % conversion of toluene methyl C−H groups to benzoyl groups is coupled with efficient hydrogen production at the cathode.

Four new 3D uranyl complexes, [(UO2)2(H2O)(ipa)2]·9H2O (1), [(UO2)2(H2O)(nip)2]·H2O·Et3NH (2), [(UO2)2(H2O)(aip)2]·Et3NH (3) and [(UO2)(hip)]2·17H2O (4) (H2ipa = isophthalic acid, H2nip = 5-nitroisophthalic acid, H2aip = 5-aminoisophthalic acid, H2hip = 5-hydroxyisophthalic acid, Et3N = triethylamine), were hydrothermally synthesized. Structural analyses reveal that compounds 1–4 consist of pentagonal bipyramidal uranyl monomers bridged via acid inkers to form a structural motif, [(UO2)2L2], serving as the foundation of the 3D framework. Two structural motifs adopt different arrangement modes to connect to two types of chains. For 1–3, uranium atoms and carboxyl groups being from two types of chains respectively are coordinated to build similar 3D frameworks, while for 4, one type of chain links to the 3D architecture by the bond of the uranium atoms and –OH of the 5-hydroxyisophthalic acid ligand. The different guest molecules and structure assemblies displayed by the four compounds are a function of the variation of substituent groups of 5-X-1,3-benzenedicarboxylic acid (X = –H, –NO2, –NH2, –OH). Furthermore, the photocatalytic properties of 2 and 4 for degradation of rhodamine-B (RhB) upon xenon lamp irradiation have been examined. Elemental analysis, infrared spectroscopy, DRS and luminescence properties were also discussed.

Achieving high shielding effectiveness in electromagnetic shielding materials relies heavily on high conductivity, yet simultaneously enhancing the absorption loss remains a persistent challenge. Consequently, the study successfully creates efficient electromagnetic shielding composite films with a unique grape-like bunch structure of hollow nanosilver (HCAF) through layer-by-layer assembly. The utilization of poly(dopamine) (PDA) to anchor nanosilver granules (AgNPs) onto cellulose nanofibers (CNF) results in the formation of CNF@PDA@AgNPs. Subsequently, a surface protection etching method is employed to etch the AgNPs, resulting in hollow nanosilver (H-AgNPs) and the generation of CNF@PDA@H-AgNPs. A composite film featuring a grape bunch structure is fabricated by interweaving high aspect ratio CNF with CNF@PDA@H-AgNPs. A substantial quantity of H-AgNPs creates an abundant interface, while the grape bunch structure establishes an efficient conductive network. That enables the composite film to exhibit excellent impedance matching, excellent conductivity loss, abundant polarization loss, and multiple reflection loss. Therefore, the conductivity of the composite film with a thickness of 148.8 μm reaches 212660 S/m, with SET, SEA, and SER 89.56, 79.03, and 10.53 dB in the X band, significantly better than the 76.9, 55.55, and 21.41 dB of the solid AgNPs composite film. The composite film also exhibits remarkable thermal conductivity (The coefficients of in-plane and out-plane thermal conductivity are 4.61 and 0.17 W/(m·K), respectively), mechanical properties, and strain sensing capabilities, making it significant potential for applications in flexible electronics and other related fields.

Li–Mg–B–H composite (2LiBH 4 + MgH 2 ) possesses a very high hydrogen storage capacity of 11.4 wt%. However, it still suffers from high operating temperature, slow kinetics, and poor reversibility. In this work, the two-dimensional Ti 3 CN MXene was first synthesized and then introduced into the Li–Mg–B–H composite. The addition of 5 wt% Ti 3 CN reduces the onset dehydrogenation temperature of the 2LiBH 4 + MgH 2 composite by about 50 °C and shortens the induction period of the LiBH 4 decomposition at 400 °C from >90 min to <10 min. The reversible capacity maintains at 8.3 wt% after 20 cycles, with a capacity retention ratio of 93%. Microstructure studies show that Ti 3 CN will partially transform to a highly-dispersed nano-TiB 2 with particle size around 5 nm. Such nano-TiB 2 could serve as an active catalyst to significantly improve the kinetics and reversibility of the Li–Mg–B–H composite. This work offers a strategy to enhancing the hydrogen storage performance of the advanced metal borohydride-based composites by addition of the MXene material and provides some new insights in understanding the role of MXene in tailoring the hydrogen storage properties of the Li–Mg–B–H composite.

The rapid development of electronics puts forward higher requirements on the low dielectric materials . Especially, the polymer-based dielectric film with low dielectric constant , high thermal conductivity , and heat-resistance is essential to the flexible electronics. However, the balance of these intended performance is still a big challenge. In this work, we reported the flexible poly (arylene ether nitrile) (PEN) fibrous composite film with low dielectric constant and high thermal conductivity by coaxial electrospinning hot-pressing technique. Interestingly, such bi-functional fibrous composite film was rationally designed by using hexagonal boron nitride (h-BN)/fluorinated PEN (PEN-F) as shell layer and polyvinylpyrrolidone (PVP) as the core layer of fibers, which could further form the porous, hollow, and balsam pear-shaped structure after the hot-pressing and dissolution process. Owing to introduction of the h-BN nanosheets , intrinsic fluorine groups of PEN-F, and hollow nanofiber structure, the dielectric constant and dielectric loss of fibrous composite film could be as low as 1.74 and 0.0092 at 1 kHz, respectively. Furthermore, the in-plane thermal conductivity of fibrous composite film could reach 0.811 W m −1 K −1 by incorporation of 7 wt% h-BN. In addition, the fibrous composite film exhibited high thermal stability (T 5 % = 498 °C and T g = 182 °C) and mechanical strength (Tensile strength = 39.2 MPa and tensile modulus = 250.9 MPa). Therefore, this work opens up an alternative method to prepare high-performance polymer composite film with low dielectric constant and high thermal conductivity, which suggests the broad application in the future flexible electronics.

Fe(II)/2-ketoglutarate-dependent dioxygenase (Fe(II)/2-KG DO)-mediated hydroxylation is a critical type of C–H bond functionalization for synthesizing hydroxy amino acids used as pharmaceutical raw materials and precursors. However, DO activity requires 2-ketoglutarate (2-KG), lack of which reduces the efficiency of Fe(II)/2-KG DO-mediated hydroxylation. Here, we conducted multi-enzymatic syntheses of hydroxy amino acids. Using (2s,3r,4s)-4-hydroxyisoleucine (4-HIL) as a model product, we coupled regio- and stereo-selective hydroxylation ofl-Ile by the dioxygenase IDO with 2-KG generation from readily availablel-Glu byl-glutamate oxidase (LGOX) and catalase (CAT). In the one-pot system, H2O2significantly inhibited IDO activity and elevated Fe2+concentrations of severely repressed LGOX. A sequential cascade reaction was preferable to a single-step process as CAT in the former system hydrolyzed H2O2. We obtained 465 mM 4-HIL at 93% yield in the two-step system. Moreover, this process facilitated C–H hydroxylation of several hydrophobic aliphatic amino acids to produce hydroxy amino acids, and C–H sulfoxidation of sulfur-containingl-amino acids to yieldl-amino acid sulfoxides. Thus, we constructed an efficient cascade reaction to produce 4-HIL by providing prerequisite 2-KG from cheap and plentifull-Glu and developed a strategy for creating enzymatic systems catalyzing 2-KG-dependent reactions in sustainable bioprocesses that synthesize other functional compounds.Keywords:Fe(II)/2-ketoglutarate-dependent dioxygenase;2-ketoglutarate generation;regio- and stereo-selective synthesis;hydroxy amino acids;sequential cascade reaction

In this report, the self-healable hydrogels containing hydroxypropyl guar gum (HPG), acrylamide (AM) and 3-acrylamidophenylboronic acid (AAPBA) were prepared through a facile strategy. The double bond in AAPBA could polymerize with AM to form copolymers. Moreover, the boronic acid groups of AAPBA can interact with cis-diol of HPG which make AAPBA act not only polymer but cross-linkers simultaneously connecting PAM and HPG chains. The mechanical strength of the hydrogels was systematically investigated as a function of AAPBA content, HPG content, AM content and pH. It was found the hydrogels exhibited higher stress, elongations and self-healing properties due to the synergistic interaction of H-bond and dynamic covalent phenylboronic (PBA)-diol ester bonds. Furthermore, the hydrogels showed yielding phenomenon depending on the content of AM and pH, which could play a vital influence on the crosslinking manners and density. The detailed discussions of the relationship between crosslinking manners and yielding phenomenon provide a better understanding on the appearance of yielding phenomenon and their correlation with hydrogel structure.
