Aqueous zinc-ion batteries persistently encounter interface issues stemming from the water-rich electrical double layer and unstable solid-electrolyte interphase, drastically compromising reversibility and cyclability. Here we show that trace amounts of nonionic amphiphilic polysorbate additives promote the formation of water-shielding electric double layer and stabilize solid-electrolyte interphase for practical zinc-ion batteries. We demonstrate that polysorbate molecules can produce preferential chemisorption and directional arrangement on the Zn anode, spontaneously forming water-shielding layer to suppress the water-related side reactions. Simultaneously, polysorbate molecules can assist the construction of organic-inorganic hybrid interphase, which effectively regulates the uniform distribution of electric field and guides preferential orientation Zn deposition to achieve ordered plating/stripping with high Zn utilization. Consequently, the polysorbate-containing electrolyte enables a long cycle life of 8060 h at 1 mA cm −2 , 1 mAh cm −2 for Zn||Zn cell, and highly reversible Zn plating/stripping in Zn||Cu cell over 3900 cycles. The full cells paired with V 2 O 5 /rGO and MnO 2 deliver the improved capacity and sustained stability.

Unveiling structure-activity correlations at the sub-nanoscale remains an essential challenge in catalysis science. During electrocatalysis, dynamic structural evolution drives the ambiguous entanglement of crystals and electrons degrees of freedom that obscure the activity origin. Here, we track the structural evolution of Ni-based model pre-catalysts (Ni(OH) 2 , NiS 2 , NiSe 2 , NiTe), detailing their catalytically active state during water oxidation via operando techniques and theoretical calculations. We reveal the sub-nanometric structural difference of NiO 6 unit with a regular distortion in the reconstructed active phase NiOOH, codetermined by the geometric (bond lengths) and electronic (covalency) structure of the pre-catalysts on both spatial and temporal scales. The symmetry-broken active units induce the delicate balance of the p and d orbitals in NiOOH, further steering the modulation of catalytic intermediate configurations and mechanisms, with improved performance. This work recognizes the fine structural differences of the active phases from the sub-nanometer scale, and quantitatively explains their influence on activity. Our findings provide a more intuitive design framework for high-efficiency materials through targeted symmetry engineering of active units.

Cinnamomum camphora chvar. Borneol essential oil (CBEO), a potential antibacterial ingredient, faces challenges in widespread use for food preservation due to its high volatility and low stability. This study aimed to enhance the stability and release properties of CBEO by preparing CBEO/β-cyclodextrin microcapsules. The ultrasound-assisted complexation (UACP) method has been developed to fabricate microcapsules containing CBEO , with β -cyclodextrin used as the wall material. The UACP process was optimized using the Box–Behnken response surface methodology. Under optimal conditions—a wall–core ratio of 4.09, ultrasound time of 52 min, ultrasound power of 617 W, and embedding temperature of 32 °C—the maximum microcapsule yield (84.93 ± 2.21%) and encapsulation efficiency (60.20 ± 1.56%) were achieved. Analysis through scanning electron microscopy, Fourier transform infrared spectroscopy, particle size distribution analysis, thermogravimetric analysis, and X-ray diffraction revealed the effective encapsulation of CBEO by UACP method. Furthermore, CBEO microcapsules exhibited favorable thermal stability and a slow-release effect. This study presents a promising approach to microencapsulation technology for the preparation of plant essential oil microcapsules.

The formation of copper deposits is closely related to hydrothermal processes. Understanding the migration of copper in hydrothermal fluids aids in reconstructing mineralization processes and deciphering deposit genesis. Copper primarily exists as Cu + and Cu 2+ in hydrothermal solutions, with redox conditions governing their interconversion. In chloride-rich geological fluids, Cu–Cl complexes are considered critical for copper transport. However, the specific types and valence transitions of Cu–Cl complexes under varying hydrothermal conditions remain poorly understood. This study employed in situ Raman spectroscopy to systematically analyze Cu + HCl and CuCl 2 + K 2 S 2 O 3 /H 2 systems under saturated vapor pressure at 25–300 °C, elucidating the effects of temperature, Cl − concentration, and redox conditions on copper speciation. In the Cu + HCl system, copper dissolved as monovalent Cu–Cl complexes. At high temperatures (> 200 °C), [CuCl 2 ] − is the dominated species, whereas [CuCl 3 ] 2− becomes prevalent at lower temperatures and higher HCl concentrations. For the Cu 2+ –Cl system, the dominant species transitioned from [Cu(H 2 O) n ] 2+ (< 50 °C) to [CuCl 4 ] 2− (100 °C) and further to [CuCl] + and [CuCl 2 ] 0 at 300 °C. The introduction of reducing agents (K 2 S 2 O 3 /H 2 ) facilitated Cu 2+ → Cu + reduction, thereby stabilizing Cu + –Cl complexes and inducing partial copper precipitation. The behavior of copper in chloride-rich hydrothermal fluids observed in this study indicates that high-temperature oxidizing fluids facilitate Cu mobilization, while cooling and redox changes promote deposition and ore minerals formation.

The experimental realization of single-crystalline high-κ dielectrics beyond two-dimensional (2D) layered materials is highly desirable for nanoscale field-effect transistors (FETs). However, the scalable synthesis of 2D nonlayered high-κ insulators is currently limited by uncontrolled isotropic three-dimensional growth, hampering the achievement of simultaneous high dielectric constants and low trap densities for small film thicknesses. Herein, we show a 2D edge-seeded heteroepitaxial strategy to synthesize ultrathin nonlayered 2D CaNb 2 O 6 nanosheets by chemical vapor deposition, exhibiting high-crystalline quality, thickness-independent dielectric constant (~ 16) and breakdown field strength up to ~ 12 MV cm −1 . The MoS 2 /CaNb 2 O 6 FETs exhibit an on/off ratio of over ~ 10 7 , a subthreshold swing down to 61 mV/dec and a negligible hysteresis. This work suggests a universal 2D edge-seeded heteroepitaxy and slow kinetic strategy for the scalable growth of 2D nonlayered dielectric and demonstrates 2D CaNb 2 O 6 nanosheets as promising dielectrics for facilitating 2D electronic applications.

Adaptive moisture and thermal management cotton fabrics can maintain human physiological comfort without requiring space heating or cooling, aligning with the goals of sustainable development, carbon neutrality, and carbon peak. However, the moisture and thermal management performance and wearing comfort of cotton fabrics require further study. In this study, mist polymerization technology and the “grafting through” polymerization method were used to graft poly[2-(2-methoxyethoxy) ethoxyethyl methacrylate] (PMEO2MA) onto the inner surface of cotton fabric and poly[ N,N -dimethyl(methacryloylethyl)ammonium propane sulfonate] (PDMAPS) onto the outer surface. The reversible wetting properties of both surfaces impart the fabric with excellent moisture and thermal management capabilities. The treated fabric reduces skin temperature by approximately 5.0 °C within 8 min when worn at 31.0 °C and increases skin temperature by around 3.0 °C–4.0 °C within 8 min when worn at 9.5 °C. This fabric, capable of rapidly managing moisture and thermal conditions in a short duration, exhibits considerable potential for application in harsh and demanding environments.

Real-time detection of acetic acid vapor is of concern for ensuring environmental and personal safety. However, acetic acid gas sensors, particularly those based on Bi 2 O 3 , often fail to meet practical performance requirements owing to their slow response characteristics and high operating temperature. To enhance sensing performance, highly permeable Bi 2 O 3 microspheres decorated by Pt-nanoparticles are rationally synthesized by a facile template method. Among the fabricated sensors, the one based on 3 wt% Pt-decorated Bi 2 O 3 demonstrated excellent sensing performance. Specifically, the sensor displayed high selectivity for acetic acid, rapid response and recovery times (22.5 and 9 s, respectively), strong resistance to interference, and good long-term stability at a low operating temperature (150 °C). Notably, the sensor exhibited an exceptionally high response of 126 to 100 ppm acetic acid—the highest reported value for Bi 2 O 3 -based sensors tested at a relatively low operating temperature in recent years. These results demonstrate that Pt-decorated Bi 2 O 3 holds strong potential for use in high-performance acetic acid sensors. Graphical abstract

Autophagy and apoplastic ascorbic acid (AsA) play important roles in plant drought tolerance. However, the trans-plasma membrane transport of AsA and its association with autophagy during drought stress are unclear. Here we report an AsA-induced autophagy pathway in plants, wherein plasma-membrane-located cytochrome b561 and DOMON domain (CYBDOM) proteins play positive roles. CYBDOM proteins from the resurrection plant Boea hygrometrica (BhDB) and Arabidopsis (AtDB1) can transport electrons across the plasma membrane using intracellular AsA as an electron donor and apoplastic monodehydroascorbic acid or Fe 3+ as electron acceptors in Xenopus laevis oocytes. Increased apoplastic AsA, autophagy and drought tolerance are observed in BhDB - and AtDB1 -overexpressing Arabidopsis compared with the wild type. CYBDOM proteins interact with respiratory burst oxidase homologue D (RbohD), which serves as the adaptor to bind autophagy related gene 8 protein (ATG8) and cargo protein for autophagic degradation. AsA increases AtDB1 protein level and its interaction with RbohD. Together, the AsA-activated CYBDOM–RbohD synergy to induce autophagy suggests a novel mechanism in plant drought and desiccation tolerance.

Vat photopolymerization (VPP) 3D printing is an optimized technology for complex-shaped ceramic cores, in which the solid loading of ceramic slurries greatly influences the microstructure and property of the final ceramic parts. However, the high solid loading of slurries is highly limited by the high viscosity. In this study, silica-based ceramic core slurries with solid loading up to 68vol.% were achieved by the composition design to optimize the performance, considering the curing, rheological, and double bond conversion rate. The slurries demonstrate superior curing and rheological performance with mass ratio of monomers being 3:2 and mass fraction of BYK111 being 4wt.%. Afterwards, the impact of solid loading on the morphology and mechanical properties was investigated. As the solid loading increases, the microstructure becomes gradually dense, leading to an improved flexural strength of 19.5 MPa. Additionally, the sintering shrinkage becomes more uniform, satisfying the casting requirements effectively. This work serves as a guide for the preparation of ceramic slurries with a high solid loading.

Acute kidney injury (AKI) frequently arises as a complication of hepatic ischemia-reperfusion injury (HIRI), yet simultaneous optical imaging of both remains challenging due to the lack of unimolecular dual-responsive probes. Herein, we report a library of hemicyanine-based chemiluminophores (HCLs) with tunable emission to second near-infrared window (725 − 1025 nm) achieved by integrating bicyclic dioxetane onto hemicyanine skeletons to develop multiple-responsive chemiluminescent probes. HCL1 and HCL5 respectively emitting at 725 nm and 1025 nm are selected to construct a cascaded activatable reporter CAR for crosstalk-free duplex chemiluminescence imaging of interlinked biomarkers. Following systemic injection to male mice, CAR preferentially accumulates in the liver and reports HIRI-associated superoxide anion (O 2 •− ), which initiates self-fragmentation and liberates the secondary reporter KIR into kidneys to report AKI-associated N-acetyl-β-D-glucosaminidase (NAG). Such mechanism allows CAR to serve as a reservoir for gradual release of AKI reporters, providing a significantly prolonged imaging window compared to co-administering separate probes. CAR further permits remote detection of HIRI-induced AKI via urinalysis. This study not only offers a powerful tool for simultaneous detection of HIRI and HIRI-induced AKI, but also highlights a unimolecular probe design for ultrasensitive detection of deeply-seated intercorrelated diseases.

The integration of photochromism and photoluminescence in functional materials presents significant challenges, particularly in achieving broad-spectrum color modulation and rapid response. In this work, we have developed sodium-doped and sodium/boron co-doped CDs that exhibit dual-mode photochromic luminescent behavior through a novel radical-mediated mechanism. The Na-CDs demonstrated a 180 nm red-shift in emission, transitioning from 450 to 630 nm. The Na, B-CDs achieved blue-shifted, multicolor emission, progressing from orange to yellow and green under 30-s UV irradiation. Notably, the photochromic states spontaneously reverted to their initial configurations without external stimuli. These phenomena arise from photoinduced electron transfer between pristine CDs and light-generated anionic radicals. Leveraging these unique photochromic properties, we implemented reversible anti-counter-feiting systems and information encryption platforms. Furthermore, the photochromic CDs exhibit daylight-responsive UV detection capabilities and are functional in plant cell imaging, significantly expanding their potential applications in optoelectronic devices.

The clinical efficacy of the antidiabetic drug acarbose is hampered by degradation by the acarbose-preferred glucosidase (Apg) from K. grimontii TD1. Understanding the catalytic mechanism of Apg can aid the design of next-generation hypoglycemic pharmaceuticals acarbose analogs. Here, we determine several crystal structures of Apg to identify the catalytic residues and the ligand-binding pocket of Apg. Structural analyses and computational modeling reveal D448 as the active nucleophile, contrasting with prior studies that assumed D336 to be the nucleophile. In addition to E373 proposed as the proton donor in previous reports, we find that R334 might be an alternative proton donor. Our experimental and computational analyses indicate the two-ring product acarviosine is the two-step hydrolyzed product, where the second hydrolysis is the rate-limiting step. Additionally, further investigation of the acarbose analogs acarstatins A and B that are resistant to Apg is conducted by computational analysis. Overall, our studies provide perspectives into the intricacies of Apg’s catalytic mechanism, contributing to the design of next-generation hypoglycemic pharmaceuticals.
