Direct air capture (DAC) is critical to achieve carbon neutrality, yet current technologies face significant barriers to widespread, cost-effective deployment. Amine-based electric swing adsorption (ESA) offers a promising low-energy, steam-free pathway, but its efficiency is fundamentally limited by an inherent 2:1 amine-to-CO 2 stoichiometric penalty. Here, we overcome this bottleneck by engineering a point defect-mediated proton trapping network into ESA sorbents, enabling a 1:1 amine-CO 2 stoichiometry. Our engineered sorbent achieves a CO 2 uptake of 6.57 mmol g −1 from 400 ppm CO 2 , a 28.8% improvement over the state-of-the-art sorbents. Regeneration is achieved with a low energy input of 3.4 GJ t −1 and exhibits a CO 2 release rate 48% faster than conventional thermal methods. N 5- d GA remains stable under 0-80% relative humidity fluctuations and at a gas velocity of 1 m s −1 . Techno-economic analysis projects DAC operating costs of $48-62 t −1 using renewable electricity, up to 78% lower than temperature swing adsorption DAC and below the $100 t −1 CO 2 target. This work presents a sorbent design and ESA process, establishing a scientifically rigorous and economically viable pathway towards gigaton-scale DAC deployment.

Kesterite Cu 2 ZnSn(S,Se) 4 (CZTSSe) solar cells suffer from significant open-circuit voltage ( V OC ) deficits due to severe interfacial and bulk recombination, restricting their power conversion efficiency (PCE) far below the Shockley-Queisser limit. This work proposes a low-temperature annealing strategy during ITO sputtering (SA) to synergistically address these challenges. The temperature applied during ITO sputtering not only improves the crystallinity, carrier concentration, and optical transmittance of the ITO layer but also promotes the diffusion of In from ITO into both CdS and CZTSSe layers. Consequently, lattice matching at the CZTSSe/CdS interface is optimized, enabling epitaxial growth. And a favorable ITO/In:CdS/In&Cd:CZTSSe structure with optimal band alignment is obtained. As a result, a champion device with a PCE of 14.29% was achieved. The SA-treating also enabled the CZTSSe solar cells to achieve the highest V OC reported to date, exceeding 590 mV. This underscores the essential role of SA processing in optimizing interface engineering and suppressing defects, thus promoting the development of low-cost, high-performance kesterite photovoltaics.

The treatment of dye-containing oil-in-water emulsions remains challenging due to membrane fouling and limited operational stability. In this study, amino-functionalized metal-organic framework (MOF) NH 2 -MIL-125 was incorporated into polysulfone (PSF) membranes via phase inversion to fabricate mixed matrix membranes (MMMs) for oil-in-water emulsion separation and light-assisted self-cleaning. The separation test was conducted at 0.2 MPa using an as-prepared sodium dodecyl sulfate (SDS)-stabilized n-hexane-in-water emulsion containing 1.0 vol% oil. Compared with pristine PSF, the optimized PN0.5 membrane showed a decrease in water contact angle (WCA) from 67.5 ± 2.0° to 22.7 ± 2.4° and an increase in underwater oil contact angle (UWOCA) from 73.0 ± 2.3° to 140.0 ± 2.6°, confirming enhanced hydrophilicity and underwater oleophobicity. PN0.5 achieved a permeate flux of approximately 245 L·m⁻ 2 ·h⁻ 1 and a separation efficiency close to 99%. Moreover, PN0.5 maintained approximately 98% separation efficiency during a seven-day cyclic filtration test. In a separate antifouling test, the membrane exhibited a low irreversible fouling ratio of 3.79%. Under irradiation with a 300 W xenon lamp for 60 min, the NH 2 -MIL-125-containing membrane promoted methylene blue (MB) decolorization and dye-foulant removal, while the irreversible fouling ratio remained low at 3.98% for the MB-containing emulsion after light-assisted self-cleaning. These results demonstrate the potential of NH 2 -MIL-125/PSF mixed-matrix membranes for treating dye-containing oily wastewater.

Calcium silicate hydrate (C-S-H) and calcium hydroxide (CH, portlandite) are the dominant hydration products of Portland cement. However, the anisotropic layered CH and uncoordinated nucleation of C-S-H and CH severely restrict the macroscopic performance of cementitious materials. Here, we report a hydrogen-bond-regulated proton transfer strategy to mechanochemically synthesize a positively charged, isotropic disordered CH precursor (CHP_H + ). This precursor serves as a growth-accelerating nucleus to trigger dual heterogeneous nucleation of CH and C-S-H, in situ forming a CH@C-S-H composite. Free energy calculations reveal that hydroxyl vacancies on CH surfaces drive spontaneous water adsorption to generate ≡Ca−OH 2 + sites, which stabilize silicate clusters and promote composite growth. The resulting cementitious material shows accelerated hydration kinetics, higher hydration heat release, and greatly improved elastic modulus and compressive strength, delivering a 5.4-fold improvement in 12 h strength over the control. This work provides an atomic-scale design principle for advanced cementitious materials by reprogramming the nucleation and growth pathways of hydration products via protonation regulation.

Black chokeberry pomace (BCB) and its water-insoluble fraction (IBCB) were incorporated into potato crisps to evaluate their effects on α,β-unsaturated aldehyde formation during frying and simulated gastrointestinal digestion. Water washing converted BCB into an insoluble fraction with undetectable soluble sugars and free amino acids, while enriching dietary fiber and nonextractable phenolics. Compared with BCB, IBCB showed higher retention of anthocyanins and flavonols during frying and greater reductions in five aldehyde endpoints, including malondialdehyde (MDA), 4-hydroxy-2-nonenal (HNE), 4-hydroxy-2-hexenal, acrolein, and 2,4-decadienal. During the static enzyme-assisted digestion model, IBCB-20 reduced late-stage MDA accumulation by 88.4% and HNE accumulation by approximately 93.1% at the 16-h simulated colonic phase. In the co-digestion experiment, the IBCB insoluble matrix decreased MDA and HNE by 63.1% and 83.9%, respectively, whereas an ABTS-matched Trolox dose decreased them by 52.5% and 53.0%. Because phenolic-aldehyde adducts were not directly characterized, these results should be interpreted as indirect evidence that the IBCB fiber matrix may provide sustained antioxidant effects and may contribute to matrix-associated carbonyl interactions. Overall, water-insoluble chokeberry pomace represents a promising formulation strategy for lowering aldehyde burden in fried snacks, but sensory evaluation, microbiota-based fermentation, cellular assays, and in vivo studies are still required to establish practical and biological relevance.

Metallocene research has influenced the development of organometallic chemistry, and the metal–nonmetal inverted half-sandwich structure (inverse metallocene) was very recently discovered. However, additional instances are required to propose the concept inverse metallocene and it remains uncertain whether metal five-membered ring structures analogous to the cyclopentadienyl anion structure exist. Herein we report the synthesis of a series of palladium analogs Pd 8 (PPh) 2 (PPh 3 ) 2 (Ph 2 P=O)(S-Adm) 5 (Pd 8 –P), Pd 6 (PPh)(PPh 3 )(S-Adm) 6 (Pd 6 ), Pd 5 (PPh)(S-Adm) 4 [(Ph 2 P) 2 O] (Pd 5 –O), and Pd 5 (PPh)(S-Adm) 4 [(Ph 2 P) 2 CH 2 ] (Pd 5 –C), identify their fundamental metal building block named five-membered Pd aromatic ring, and reveal their conjugation‒photothermy correlation. In particular, we report an average NIR-II photothermal conversion efficiency per metal atom of 14.7% and the stability of the five-membered Pd aromatic ring, as illustrated by the fact that Pd 5 –C maintained photothermy performance for >10 heating–cooling cycles even after the ligands were removed. We further demonstrate the great potential of inverse palladocenes in areas such as laser shielding, high-temperature degradation, ignition, and temperature/light control. These results declare the research and application start of a type of materials named inverse palladocenes.

Neuroimmunology has garnered significant attention due to its role in immune regulation, particularly in cancer, where infiltrating neurons can influence antigen presentation, T-cell activation, and cancer metastasis, ultimately leading to an inadequate immune response. Here, we integrate manganese-doped titanium-based metal-organic framework (MOF) piezoelectric materials (MT), coated with neuron-derived membranes from dorsal root ganglia, into microneedles (MN) to create a piezoelectric microneedle (MT MN) patch designed to disrupt neuron-immune crosstalk in melanoma. A single administration of MT via microneedle patch stably deposits the MT at the melanoma site in female mice to accelerate the nociceptor neurons targeting. Upon moderate ultrasound stimulation, the MT facilitates the internalization of TRPV1 and activates the cGAS-STING pathway, resulting in the reduction of Ca 2+ influx in nociceptor neurons. This ultimately limits the production of calcitonin gene-related peptide (CGRP) and substance P (SP). Consequently, to rescue the tumor immune microenvironment damaged by infiltrated neurons, MT MN is utilized to inhibit the growth and infiltration of nociceptor neurons, highlighting a promising manner for interfering neuron-immune crosstalk in melanoma to enhance cancer immunotherapy. Activation of nocireceptors can contribute to immunosuppression in cancer. Here the authors report the design and characterization of nociceptor neuron-targeting piezoelectric microneedles, showing disruption of pro-tumorigenic neuron-immune crosstalk and reinvigoration of anti-tumor immunity in melanoma.

Wide-bandgap perovskite top cells for tandem photovoltaics are constrained by voltage deficit and non-radiative losses. Here we design a series of perovskite derivatives featuring dynamically disordered cyanate anions and demonstrate that the dynamic anionic sublattice engineering alters crystallization kinetics, directing the epitaxial growth of a coherent bulk heterojunction with large-grained morphology. The cyanate anions provide chemical and electronic passivation at grain boundaries and interfaces, neutralizing deep-level traps and suppressing non-radiative recombination. The single-junction wide-bandgap perovskite solar cell fabricated with this method has a power conversion efficiency of 24.35%. When integrated as the top cell in a monolithic perovskite–silicon tandem, a power conversion efficiency of 34.79% (certified 34.29%) is achieved. Exceptional operational stability is demonstrated, with 95% initial performance retained after 1,100 hours of continuous illumination under the ISOS-L-1 protocol. Extended real-world testing over 1,300 hours under the ISOS-O-2 protocol further demonstrates its enhanced stability. This work establishes the rational design of perovskite anionic synthesis chemistry as a powerful route to overcome the intrinsic stability–performance trade-off in perovskite–silicon tandem cells.

To address the growing need for lightweight and multifunctional stealth materials in modern protective applications, this study presents an innovative melamine foam (MF)-based composite featuring an asymmetric dual-nano conductive network with integrated absorption-dominated electromagnetic interference (EMI) shielding, infrared (IR) stealth, and flame retardant properties. Inspired by Salisbury screen, the composites employ MF as an interlayer and flame-retardant thermoplastic polyurethane (TPU) nanofiber membrane as a substrate. The architecture features a carbon nanotubes (CNTs)-modified impedance matching nanofiber layer as the top absorber and a silver nanoparticles (AgNPs)-modified nanofiber layer as the highly conductive reflective bottom. Precise control of CNTs content and interlayer thickness enables tunable electromagnetic waves (EMWs) absorption, yielding a low reflection (0.03) and high EMI shielding effectiveness (79.23 dB) at 4.40 mm. Even at 1.40 mm, effective absorption-dominated shielding is maintained. And the performance remains stable under ultrasonic, compression, and bending, demonstrating high durability. Especially, the mechanism behind achieving absorption-dominated EMI shielding at a reduced thickness, which relies on destructive interference of EMWs enabled by the asymmetric dual-nano conductive network, is thoroughly elucidated. Additionally, the composite exhibits superior IR stealth and self-extinguishing properties. This work offers a feasible strategy for designing high-performance stealth materials with strong potential for personnel and communication equipment protection.

Triggering the adsorbate evolution and lattice oxygen mechanisms coupled path holds promise for overcoming the activity-stability trade-off of oxygen evolution reaction (OER). However, achieving precise regulation and activation of multiple OER pathways via 3d-metal modification strategy remains challenging due to the external effects of crystal fields and coordination environments. Herein, we propose an atomic-dispersed rare earth substitution strategy to construct a spatially partitioned reaction mechanism, and achieve dual activation between adsorbate evolution and lattice oxygen mechanisms. The strong shielding effect of 5 s /5 p electrons in RE significantly reduces the influence of the external environment on the 4 f orbitals, thereby enhancing the controllability of the reaction pathway. The optimized Sm-NiMoO 4 exhibits favorable OER performance. At an industrial temperature of 70 °C, the OER in simulated seawater exhibits an overpotential of only 214 mV at 0.5 A cm −2 , while maintaining stability for 1500 h. Preliminary techno-economic analysis reveals that the cost of hydrogen produced from the Sm-NiMoO 4 is US$2.56 kg −1 . This synthetic strategy and mechanism analysis represent a valuable contribution towards achieving industrial-scale seawater hydrogen production.

Peritoneal metastasis (PM) of colorectal cancer (CRC) remains a major therapeutic challenge due to the limited efficacy of current systemic and intraperitoneal treatments. To overcome these limitations, we developed an injectable, self-healing hydrogel constructed from a dual dynamic cross-linked network formed by borate ester and Schiff base bonds between phenylboronic acid-modified carboxymethyl chitosan (CMCS-PBA) and oxidized dextran (ODEX). This hydrogel was engineered for sustained intraperitoneal co-delivery of oxaliplatin (OXA) and resveratrol-loaded mesoporous silica nanoparticles (MSNs@RES). The system exhibited excellent biocompatibility and significantly inhibited cancer cell proliferation, migration, and invasion while inducing apoptosis and immunogenic cell death (ICD) in vitro. In a murine model of CRC peritoneal metastasis, the dual-drug-loaded hydrogel markedly suppressed tumor progression, reduced ascites formation, and prolonged survival. Proteomic analysis further revealed that treatment significantly modulated key signalling pathways, including HIF-1α-mediated angiogenesis, apoptosis-related cascades, and TGF-β-driven epithelial-mesenchymal transition (EMT). Collectively, this work presents a rationally designed localized delivery platform with significant potential for the treatment of colorectal cancer peritoneal metastasis.

Diabetic wounds are characterized by persistent inflammation, impaired angiogenesis, and delayed tissue regeneration, yet effective strategies to regulate the pathological immune microenvironment remain limited. Here, integrated single-cell transcriptomics and multi-omics analyses revealed significant enrichment of endoplasmic reticulum stress (ERS)-related signaling in pro-inflammatory macrophages within diabetic wounds, suggesting a potential mechanism driving chronic inflammation. To target this process, we developed an injectable dynamic hydrogel (GPOK-2@EVs) incorporating Artemisia argyi-derived extracellular vesicles (EVs) for localized immunomodulatory therapy. The hydrogel was formed through dual dynamic crosslinking between phenylboronic acid-modified gelatin and oxidized konjac glucomannan, providing self-healing capability, injectability, tissue adhesion, and pH/ROS-responsive degradation for sustained EV release. In vitro experiments demonstrated that GPOK-2@EVs exhibited excellent biocompatibility and effectively reprogrammed macrophages toward an anti-inflammatory phenotype, accompanied by reduced inflammatory cytokine secretion, alleviated ERS activation, decreased ROS accumulation, and improved mitochondrial integrity. GPOK-2@EVs significantly enhanced endothelial angiogenic activities, including cytoskeletal remodeling, tube formation, and migration. In a diabetic mouse wound model, GPOK-2@EVs accelerated wound closure, promoted granulation tissue formation and collagen deposition, enhanced vascularization, and suppressed inflammatory and ERS responses. These findings demonstrate that EV-loaded dynamic hydrogels can modulate the inflammatory microenvironment and promote diabetic wound regeneration, providing a promising biomaterial strategy for chronic wound therapy. Graphical GPOK-2@EVs hydrogel promotes wound healing through ROS-responsive EV release, macrophage modulation, inflammatory cytokine reduction, and enhanced angiogenesis.
