Purpose Cadmium (Cd) isotope fractionation related to various components in soils provides useful information on Cd biogeochemical behaviour in the natural environment. Existing studies focus solely on Cd isotope fractionation during adsorption on environmentally relevant surfaces (e.g., clay minerals) but poorly document Cd isotopic variation during desorption, particularly in the case of partial desorption. Studying Cd isotopic behaviour during adsorption–desorption on clay minerals and soil benefits Cd fate tracing. Materials and methods Here, Cd isotope fractionation during adsorption–desorption was investigated on kaolinite and montmorillonite at different solution pH and initial Cd concentrations, and in an albic soil rich in clay minerals but low in organic matter and iron-manganese oxides. In addition, the clay particle fraction (< 2 μm) of the albic soil was also separated and used for adsorption–desorption experiment and isotopic analysis. Results and discussion Solution pH and Cd concentration significantly affected Cd adsorption at different sites and Cd desorption rate on the surfaces of the two clay minerals but led to negligible Cd isotope fractionation during adsorption and desorption. This strongly suggests similar Cd isotope fractionations induced by the two different adsorption sites on the clay minerals. Negligible isotope fractionation was also observed during adsorption or desorption in the albic soil and its clay particle fraction (< 2 μm; Δ 114/110 Cd adsorption = − 0.07 to − 0.06‰ and Δ 114/110 Cd desorption = − 0.08 to − 0.05‰). Cadmium adsorption on montmorillonite which dominated Cd adsorption on the soil studied and the clay particle fraction is suggested as the explanation for the negligible Cd isotope fractionation during soil adsorption and desorption. Conclusions This work provides preliminary data on Cd isotope fractionation during adsorption and desorption in actual soils with multiple reactive surfaces and indicates that the contribution of kaolinite and montmorillonite to Cd isotope fractionations during adsorption/desorption in soils may be neglected, and in some clay-rich soils ion exchange may not lead to significant Cd isotope fractionation.

Replacing the oxygen evolution reaction with more thermodynamically favourable organic oxidation reactions (OORs) can enable energy-efficient hydrogen evolution and hydrogenation. However, cathodic reduction rates are limited by sluggish OORs. Herein, we report a decoupled electrolysis strategy using a solid redox reservoir (RR) to realize an optimized hydrogen evolution reaction (HER) paired with valuable chemical synthesis. The decoupled system with a rechargeable capability features a HER coupled with RR oxidation for electricity storage, which is followed by the conversion of OORs (e.g., ethylene glycol, glycerol) into value-added chemicals coupled with the reduction of the oxidized RR to generate electricity. The fast kinetics of RR oxidation and membrane-free cell operation optimize the HER rate. The value-added chemicals and electricity are cocreated during the discharge process, offering more economic benefits. This decoupling design is universally applicable to other OORs-paired reduction systems (e.g., acetylene-to-ethylene semihydrogenation) to synthesize various chemicals for electricity storage and generation, paving a sustainable avenue for H 2 production/hydrogenation and chemicals manufacturing.

Barium strontium titanate (BST) ceramics have been extensively studied by many scholars because they combine the high polarization strength, high breakdown strength, and low dielectric loss. It is reported that incorporation of Bi(Mg, Zr)O₃ (BMZ) into BST ceramics can enhance relaxor behavior, resulting in improved energy storage efficiency. However, the temperature stability and energy storage efficiency of these materials remain insufficiently explored, requiring further research to meet increasingly demanding operating conditions. In this work, La₂O₃ was doped into 0.84Ba₀.₈Sr₀.₂TiO₃-0.16Bi(Mg₀.₅Zr₀.₅)O₃ (BST-BMZ) to form 0.84(Ba₀.₈Sr₀.₂)₁₋₁.₅ ₓ La ₓ TiO₃-0.16Bi(Mg₀.₅Zr₀.₅)O₃ [(BS)₁₋₁.₅ ₓ La ₓ T-BMZ] ( x = 0.02, 0.04, 0.06) composite ceramics. The effects of La₂O₃ doping on phase structure, microstructure, dielectric properties, and energy storage performance of ceramics were systematically studied. The results show that the energy storage density ( W ) and recoverable energy storage density ( W rec ) of the ceramics both decrease with the increase of La₂O₃, while the energy storage efficiency ( η ) of the ceramics improves due to the reduction in remnant polarization intensity; η reaches its maximum at x = 0.02. The sample demonstrated excellent temperature stability (30–150 °C) with W rec variation < 15% and η fluctuation < 10%, meeting the X7R standards. The results show that the (BS)₀.₉₇L₀.₀₂T-BMZ ceramics are promising candidates for high-stability energy storage applications.

Polyamide nanofiltration membranes have been widely used in seawater desalination and water treatment. Enhancing water permeability while sustaining high rejection in nanofiltration (NF) membranes has garnered significant research interest. In this study, we combined the MXene intermediate layer and amine monomer enrichment by one-step co-deposition strategy and then fabricated MXene-based composite nanofiltration film (MCF) via interfacial polymerization (IP). Ethylenediamine (EDA) adsorbed onto MXene surfaces via hydrogen bonding or electrostatic interactions, thereby improving MXene dispersion, enhancing interfacial bonding with the polyamide (PA) selective layer, and optimizing the composite membrane structure. MXene doping enhanced surface roughness, hydrophilicity, and electronegativity of the composite membrane, strengthening Donnan exclusion and size sieving. The optimized membrane sample has a water permeability of 103.8 L m -2 h -1 at 6 bar, rejection rate for methylene blue (MB) and Congo red (CR) > 99%, and a high rejection rate of metal ions (Mg 2+ , Cu 2+ , and Ca 2+ > 93%, Na + >83%). This membrane overcomes the traditional trade-off effects between water permeance and salt selectivity, achieving simultaneous improvement in water flux and rejection rate. This work is expected to provide a new way for the preparation of nanofiltration membranes with excellent performance.

Continuous in vivo monitoring of biomarkers remains challenging due to limited sensitivity, integration, and biocompatibility. Here, we report an integrated microneedle-based electrochemiluminescence device (MN-ECLD) for real-time detection of protein biomarkers in interstitial fluid. Leveraging hydrogen-bonded organic frameworks with ultrabright, biocompatible electrochemiluminescence, the emitters were incorporated into porous gold-coated microneedle arrays and regulated via interface-specific Y-shaped probes, enabling efficient coreactant-free signal generation. The device achieved ultrasensitive protein detection in vitro with a linear range of 100 fg/mL to 10 ng/mL, a detection limit of 21.3 fg/mL, and stability over 12 days, delivering an 87-fold sensitivity enhancement over conventional emitters. In vivo, MN-ECLD enabled real-time monitoring of cardiac biomarkers, achieving early warning of acute myocardial infarction in rats and pigs, with biomarker trends consistent with serum ELISA. This work establishes a versatile platform for continuous in vivo diagnostics of acute cardiovascular and metabolic disorders.

Widespread contamination by Pb(II) and Cd(II) poses persistent environmental and public health risks, while achieving selective removal with a clear mechanistic understanding in multicomponent systems remains challenging. Herein, a MgFe-MoS₄-LDH/BC hybrid composite was synthesized via co-precipitation followed by MoS₄ 2 ⁻ intercalation to regulate interlayer chemistry and introduce sulfur-based active sites. Adsorption kinetics followed a pseudo-second-order model, and equilibrium data were well described by the Langmuir model, indicating dominant chemisorption. Under optimized conditions (C₀- Pb = 100 mg/L, C₀- Cd = 20 mg/L, pH = 6.0, dosage = 0.2 g/L), the composite achieved removal efficiencies of 99.53% for Pb(II) and 85.71% for Cd(II). In binary systems, Pb(II) showed stronger competitive behavior, exhibiting only a 4.7% capacity reduction compared to 9.4% for Cd(II). Thermodynamic analysis confirmed that adsorption was spontaneous and endothermic. Combined XRD, FTIR, XPS, and density functional theory (DFT) analyses revealed that metal immobilization was governed by complexation with oxygen- and sulfur-containing groups, surface precipitation (Pb₂(SO₄)O and Cd(OH)₂), and electrostatic attraction. DFT calculations further demonstrated stronger Pb–S interactions, explaining preferential Pb(II) adsorption. The composite maintained high stability after five regeneration cycles, and key scientific challenges and future innovation pathways are summarized to guide practical application. This work provides a rational strategy for designing selective LDH-based composites for heavy-metal remediation.

This study develops high-performance zinc-ion battery cathodes through dual engineering of vanadium-alloyed MXene and its heterointerface with sodium vanadate (NaV 3 O 8 ·1.5H 2 O, NVO). By selectively etching (Ti 1-x V x ) 3 AlC 2 MAX precursors (NaF/HCl, 60℃, 48 h), we synthesized (Ti 1-x V x ) 3 C 2 MXene solid solutions where V-substitution optimizes electron conductivity. When composited with NVO, the 20 wt% (Ti 0.7 V 0.3 ) 3 C 2 /NVO cathode delivers remarkable specific capacities of 221.6 mA h g −1 at 10 A g −1 – surpassing pure NVO by 4.0-fold and Ti 3 C 2 /NVO by 2.5-fold – and maintains 195 mA h g −1 after 5,000 cycles (1.7 times of pure NVO and 4.1 times Ti 3 C 2 /NVO), outperforming state-of-the-art vanadate cathodes. Mechanistic analysis reveals that while NVO enables reversible Zn 2+ redox reaction, the V-alloyed MXene simultaneously constructs a 3D conductive network suppressing electrode degradation and creates low-energy Zn 2+ migration channels at interfaces via lattice distortion. Collectively, this interface engineering strategy unlocks ultra-stable zinc storage at practically high rates (10 A g −1 ), providing a pathway for next-generation zinc storage cathode.

In nature, nuclear DNA complexed with histone form highly condensed chromatin via loop extrusion and microphase separation, yielding physically constrained solid-like structures. Inspired by this natural compaction, here we demonstrate that freezing-induced crystallization pressure and freeze-concentration effects trigger solid-liquid microphase separation for efficient DNA compression. Freezing compress various nucleic acids (single stranded DNA, molecular beacons, siRNA, plasmid DNA) into high-density states that self-assemble into nanoparticles (DNA-NPs, MB-NPs, siBcl-2-NPs, siPLK1-NPs, pEGFP-NPs). Molecular dynamics simulations reveal that ice crystal growth increases solute concentration, enhancing DNA intermolecular interactions to form supramolecular chains. Stress at advancing ice-liquid interfaces further orders and compacts these supramolecular chains into nanoparticles. In breast cancer cells, MB-NPs detect miRNA-21; siBcl-2-NPs downregulate Bcl-2 protein; siPLK1-NPs exhibited antitumor effects; and pEGFP-NPs mediate green fluorescent protein (GFP) expression. This freeze-induced self-assembly strategy replaces chemical synthesis with physical constraints, establishing a versatile platform for facile production of nucleic acid nanoparticles.

Unsaturated vegetable fatty acids, as a renewable resource, are abundantly present in vegetable oils, exhibiting significant potential for the synthesis of bio-polyols and bio-based polyurethanes (PUs). Herein, castor oil (CO) and tea seed oil (TSO) were selected as feedstocks to fabricate bio-based hydrophilic chain extenders (HCEs) for water-based polyurethane (WPU). Firstly, the raw oils were treated through a three-step process involving saponification, acidification and urea inclusion purification, yielding unsaturated ricinoleic acid (RA) and oleic acid (OA) with high purities of 93.99% and 92.72%, respectively. Subsequently, an efficient thiol-ene click reaction was carried out to prepare amphiphilic ricinoleic acid-based chain extender (RACE) and amphiphilic oleic acid-based chain extender (OACE) under ambient conditions (1 h, room temperature) with relatively lower molecular weight ( M w ) and accurate functionality ( f − OH = 2 ). The activation energies for the reactions of RACE/OACE and dimethylolpropionic acid (DMPA) with isophorone diisocyanate (IPDI) were evaluated via non-isothermal DSC kinetic analysis (Kissinger method and Ozawa method), and the apparent activation energy ( Ea from Kissinger/ Eo from Ozawa) values were found to be 76.66/78.88 kJ·mol − ¹ for RACE and 74.58/76.91 kJ·mol − ¹ for OACE, respectively, which were slightly higher than that of DMPA (Ea/Eo = 73.01/75.32 kJ·mol − ¹). Application of these bio-HCEs for preparing WPU revealed that the particle size and absolute zeta potential of emulsion with more than 0.0248 mol bio-HCEs were equivalent to those of the emulsion with 0.0192 mol DMPA, and the resultant WPU films showed enhanced broken elongation, increased water contact angles, and reduced water absorption ratio. Collectively, the significance of this work resides in providing a feasible and potentially universal strategy for fabricating bio-HCEs from natural unsaturated oils and offering a sustainable alternative for the advancement of WPU.

Radiotherapy is a standard treatment for thoracic malignancies, but it frequently leads to radiation‑induced heart disease (RIHD), a serious and dose‑limiting complication for which no targeted therapies are currently available. Total extracts from Abelmoschus manihot (L.) (TEA), known for their cardioprotective properties, are widely used in treating various ischemic heart diseases. Here, we identify ferroptosis driven by the NOX4/SLC7A11/GPX4 axis as a core mechanism of RIHD, with GPX4 serving as the non‑redundant downstream executor. TEA effectively modulates this axis; however, it lacks cardiac selectivity, which may compromise antitumor efficacy. To overcome this barrier, we developed, characterized, and evaluated a novel nanoplatform consisting of TEA‑loaded PLGA nanoparticles conjugated with a primary cardiomyocyte‑specific homing peptide (PCM), further integrated with low-intensity focused ultrasound (LIFU)‑triggered on‑demand release (TEA@PLGA‑PCM). This system achieves superior myocardial accumulation, effectively improves cardiac function, reverses pathological remodeling, and normalizes ferroptosis markers as well as NOX4/SLC7A11/GPX4 protein expression. In summary, we successfully constructed a novel nanoplatform that represents a promising strategy for integrated targeted delivery and synergistic therapy in RIHD management. Graphical

Traditional hydrogels are limited by their loose three-dimensional network structure, inadequate mechanical strength, and insufficient synergistic antibacterial and antioxidant activities, which restrict their application as high-performance wound dressings. In this study, a graphene oxide (GO)-reinforced ternary composite hydrogel wound dressing (PVA/CS-GA/GO) based on polyphenol-modified chitosan and polyvinyl alcohol was successfully fabricated via a green repeated freeze–thaw process. The effects of GO incorporation on the microstructure, mechanical properties, antibacterial activity, and antioxidant performance of the composite hydrogels were systematically investigated. The results demonstrated that, at the optimal GO content, the composite hydrogel exhibited a tensile strength of 9.3 kPa and an elongation at break of 2163.7%, representing approximately 1.2-fold and 1.3-fold increases, respectively, compared with the PVA/CS-GA hydrogel. Moreover, GO incorporation further enhanced the antibacterial and antioxidant performances of the hydrogel, achieving a maximum antibacterial rate of 99.8% against Escherichia coli ( E.coli ) and increasing the DPPH radical scavenging activity to 94.8%, corresponding to an approximately 1.9-fold improvement over the PVA/CS-GA hydrogel. In addition, the composite hydrogel exhibited excellent structural stability and biocompatibility, simultaneously achieving mechanical reinforcement and multifunctional performance enhancement. These findings provide a theoretical basis for the design and development of high-performance multifunctional hydrogel wound dressings.

Plasmon–exciton Fano interference provides an efficient channel for coherent energy transfer, and the plasmon resonance energy transfer (PRET) peak is usually observed around the Fano dip at the exciton resonance. In this work, we achieve tunable multiple Fano interferences and multichannel PRET by strategically coupling five excitonic resonances (labeled as M, D h , D j , H, and J) of assembled IR806 molecules with Au nanobipyramids and nanorods (AuNBPs and AuNRs, respectively). Notably, owing to orientation-dependent molecule–plasmon coupling in the IR806/AuNBP hybrids, we observe two PRET peaks with opposite signs of Fano factor \(q\) . One PRET peak remains fixed near the J-aggregate exciton resonance at ~900 nm, whereas the other is located around the plasmon resonance and tuned from 710 to 920 nm. The total PRET reaches a maximum when the two PRET peaks are tuned into spectral overlap. Furthermore, our newly developed semiclassical model quantitatively reproduces these features, which reveals that PRET enhancement arises from the superposition of multiple Fano interferences. These findings provide a novel strategy to enhance the efficiency and tunability of the PRET, opening avenues for advanced applications in ultrafast optical information processing and highly sensitive photodetectors.
