The proliferation of distributed Internet of Things (IoT) nodes and wearable electronics demands sustainable, high-performance power sources capable of harvesting ambient mechanical energy. However, current piezoelectric energy harvesters (PEHs) face a critical efficiency–mechanics–sustainability trilemma. Here, we report a fully water-processed, bio-derived piezocomposite that overcomes these limitations by coupling Schottky-type interfacial electronic engineering with a dynamically hydrogen-bonded molecular network. We demonstrate that in situ synthesized copper–piezoceramic (Cu@KNN; KNN, (Na 0.5 K 0.5 )NbO 3 ) Schottky-type interfaces introduce built-in electric fields to actively regulate charge transport, thereby suppressing polarization screening and intensifying local field distribution to maximize polarization efficiency and the piezoelectric response—a fundamental departure from traditional passive dielectric tuning. Concurrently, we engineer a cellulose matrix where small-molecule modifiers (glucose and urea) reorganize the rigid structure into a dynamic network that accommodates deformation through reversible hydrogen-bond breaking and reformation. The resulting harvester exhibits exceptional stretchability (up to 269% strain) and durability (>8000 cycles), delivering a high pressure sensitivity of 1.67 V kPa −1 and an instantaneous power output of ∼940 µW—sufficient to directly power commercial electronics and charge energy storage units. This work establishes a scalable, eco-friendly paradigm for designing mechanically adaptive energy harvesters, paving the way for sustainable, self-powered bio-integrated electronics.

Hydrogenation of aromatic compounds under mild conditions remains challenging because of the high stability of aromatic π systems. Here, we report a physically mixed catalyst comprising rhodium (Rh) and cobalt (Co) nanoparticles embedded in montmorillonite (MMT) that overcomes this limitation. The enhanced activity arises from dynamic interparticle cooperation: Rh nanoparticles selectively dissociate H2, and the resulting hydrogen intermediates are transferred through particle collisions to Co nanoparticles, where aromatic hydrogenation occurs. This cooperative process can be finely regulated by tuning the oxidation states of the individual metal nanoparticles, leading to catalytic performance surpassing that of corresponding Rh−Co alloy catalysts (initial rate: 45 vs 9 μM s-1). Combined experimental and computational investigations reveal that cooperative catalysis can be quantitatively described using linear regression analysis and thereby be predicted through the rate ∼k × (Co2+/Co3+)/(Rh0/Rh3+). Our findings establish a data-driven statistical approach for designing high-performance bimetallic catalysts based on dynamic interparticle interactions.

Electrochemical bicarbonate reduction reaction offers a promising pathway of integrating carbon capture and conversion, which could bypass the energy-intensive upstream CO 2 regeneration and downstream CO 2 separation processes. Since the limited in-situ CO 2 ( i -CO 2 ) generation at the electrochemical interface, designing catalysts with highly exposed active sites and optimized structures is the key to achieve efficient bicarbonate reduction. In this work, we prepared a series of NiCu-based porous catalysts, using SiO 2 hard templates of different sizes to tune the pore structure. There exist an optimal mesopore size that could balance the mass transport, local i -CO 2 enrichment, and active-site distribution in bicarbonate electroreduction to CO. The optimal catalyst NiCu-TE achieved a bicarbonate-to-CO electrolysis at 100 mA cm −2 with 92.4% Faradaic efficiency (FE) and 41.3% energy efficiency (EE) in the membrane electrode assembly (MEA). It maintained a FE CO of 68.3% at a current density of −300 mA cm −2 . We found that pore architecture engineering, rather than pore size alone, is crucial in constructing efficient electrochemical microenvironments for bicarbonate electroreduction.

Single-crystal X-ray diffraction is one of the most reliable techniques for elucidating the molecular structures, while it requires high-quality single crystals. The crystalline mate (CM) strategy has recently emerged as an effective method to induce rapid and selective co-crystallization. Here, we demonstrate that this strategy can be reliably extended to ionic systems using the neutral trinuclear silver pyrazolate complex Ag3Pz3 as a crystallization mate. By regulating solvent polarity, two co-crystals of silver pyrazolate berberine hydrochloride Ag3Pz3·BCl, SF (sandwich form) and NSF (non-sandwiched form), were obtained. In SF, neutral Ag3Pz3 simultaneously engages the Cl− anion via π-acid/base contacts and the berberine cation through weak Ag⋯O coordination. Remarkably, SF can also be crystallized directly from crude Coptis chinensis extract without prior purification. In NSF, due to the influence from methanol or ethanol, Ag3Pz3 rearranges into a rare anionic Ag3Pz4 cluster that serves as the counterion to berberine. These results establish solvent polarity as a decisive factor governing CM-mediated co-crystal assembly and broaden the applicability of the crystalline-mate concept to ionic systems.

Multi-enzyme immobilization offers promise for sensitive glucose detection, but traditional random co-immobilization hampers spatial control. Here, a compartmentalized system (HRP.PDA.GOx@NPC-10) was constructed by localizing GOx and HRP in the inner and outer polydopamine layers on hierarchical porous carbon spheres. This method can precisely control the spatial arrangement of enzyme molecules, effectively reduce the inhibitory effects of H2O2, and enhance the catalytic efficiency of multi-enzyme catalysis. The immobilization yields of GOx and HRP reached 54.6% and 65.0%, respectively. The resultant HRP.PDA.GOx@NPC-10 exhibited 1.65-folds higher activity than free enzymes and maintained favorable stability under extreme pH and temperature conditions. After 7 cycles, HRP.PDA.GOx@NPC-10 retained 75.66% of its initial activity, demonstrating reusability. Especially, HRP.PDA.GOx@NPC-10 has been demonstrated to possess a glucose detection limit as low as 0.28 μM and a reaction time of only 3 min, indicating its potential for practical glucose detection.

Polydiacetylene (PDA) materials are typically obtained through solid-state topochemical polymerisation of diacetylene monomers, a process that strongly depends on precise molecular packing and often leads to limited control over molecular weight and dispersity. Herein, we report a co-assembly-confined polymerisation strategy for the synthesis of polydiacetylene acids with intrinsically narrow dispersity. Phenyl diacetylene acid and 1-naphthalenemethylamine form co-assembled precipitates via acid – base interactions and aromatic stacking, providing a spatially restricted environment that satisfies the geometric requirements for topochemical polymerisation. Upon UV irradiation, efficient polymerisation of diacetylene units occurs within the precipitated phase. Subsequent side-chain amidation renders the polymers soluble, enabling solution-state molecular weight characterisation. Gel permeation chromatography reveals consistently narrow dispersity (Đ =1.1 ~ 1.2) across different polymerisation temperatures, while the apparent molecular weight remains tunable. This work demonstrates a simple and reproducible materials-oriented strategy to suppress chain-length divergence in polydiacetylene systems, offering new opportunities for controlled PDA materials.

FeCu-FeO x @SFCu 0.24 M-DP/RP enables ethylene–electricity cogeneration from ethane in oxide-ion-conducting SOFCs. • FeCu–FeO x promotes C–H bond activation and facilitates ethane dehydrogenation. • The cell achieves 78.4% ethane conversion and 81.7% ethylene selectivity at 750 °C. • Stable operation is sustained for 400 h with negligible performance degradation and coke deposition. Steam cracking of alkanes such as ethane accounts for over 90% of global ethylene production, but relies on energy-intensive, high-temperature pyrolysis, leading to significant carbon emissions and complex by-products that require costly purification. Enabling the co-generation of ethylene and electrical energy in oxide-ion-conducting solid oxide fuel cells (SOFCs), we design a highly selective anode for the electrochemical oxidative dehydrogenation of ethane (EOD-eth). The anode consists of a hierarchical heterostructure featuring oxygen-vacancy-rich FeCu-FeO x anchored onto a Sr 2 Fe 1.26 Cu 0.24 Mo 0.5 O 6-δ double-perovskite/Ruddlesden-Popper matrix (FeCu-FeO x @SFCu 0.24 M-DP/RP). The SOFCs demonstrate outstanding performance, maintaining CO 2 -free operation for over 400 h, while delivering a high-power density of 0.51 W cm −2 with an ethylene selectivity of 81.7% and an ethane conversion rate of 78.4% at 750 °C. Mechanistic investigations reveal that FeO x acts as both an effective oxygen-ion channel and an oxygen storage reservoir, activating ethane C–H bonds and promoting dehydrogenation, while FeCu enhances both ethylene selectivity and electronic conductivity. Beyond this specific reaction, the FeCu–FeO x –SFCu 0.24 M-DP/RP architecture embodies the essential attributes universally required of fuel electrode—including multivalent redox adaptability, robust structural resilience, and compatibility with diverse hydrocarbon or syngas fuels—thereby representing a broadly applicable catalytic platform for next-generation fuel-flexible SOFCs.

Antibiotics, as typical emerging contaminants posing significant ecological risks, are frequently detected in global coastal environments. Their biotransformation in marine environments depends on the stress responses of functional microbial communities, while the underlying response mechanisms remain unclear. Through integrated metagenomic and metabolomic approaches, this study systematically investigated the structural and functional responses of marine microbial communities during the co-metabolic degradation of sulfamethoxazole (SMX), a representative antibiotic. A marine microbial consortium was employed for SMX co-metabolism with alginate, prototypical marine natural organic matter, as the co-substrate. Results revealed that under SMX stress, the microbial community underwent a marked shift in OTU composition, alongside significant increases in richness and diversity. The dominant functional taxon Vibrionaceae exhibited a significant decrease in relative abundance from 97.0% to 82.7%, while Paracoccaceae with SMX degradation potential and other low-abundance (<0.01%) functional taxa were significantly enriched, collectively sustaining stable alginate metabolism and facilitating SMX co-metabolism. Co-occurrence network analysis revealed enhanced interspecies associations. Moreover, the functional profile of the microbial community was profoundly reshaped. Specifically, the microbial community activated adaptive responses, enhancing TCS activation, EPS and endospore production, flagellar motility and chemotaxis, antioxidant capacity and DNA repair, and antibiotic resistance, to mitigate the toxicity of SMX and its intermediates. Concurrently, metabolic strategies were altered via regulation of key pathways (e.g., carbohydrate metabolism and amino acid metabolism), which increased by 7.8% and 17.5% in relative abundance compared to the control, boosting energy supply and SMX-degrading enzyme synthesis to enable SMX co-metabolism. This study provides new insights into the response mechanisms of marine microbial communities to SMX stress and the ecological risk assessment of antibiotics in coastal waters.

Triple-Negative Breast Cancer (TNBC) represents a highly aggressive subtype of breast cancer with an unfavorable prognosis, characterized by minimal immune infiltration and pronounced immune suppression, resulting in a limited response to immunotherapy. In this study, a multifunctional Arsenene-Vanadene nanodot (AsV) drug delivery system is introduced, which responds to the tumor microenvironment by releasing arsenic and vanadium. Arsenic undergoes oxidation to generate highly toxic trivalent arsenic, which induces apoptosis in tumor cells while utilizing apoptotic cell debris to transiently activate the immune system. Additionally, arsenic binds to cysteine, indirectly facilitating ferroptosis. Concurrently, vanadium's redox cycling properties are harnessed to trigger a Fenton-like reaction, promoting lipid peroxidation. Furthermore, ferroptosis is enhanced through the depletion of glutathione and inactivation of glutathione peroxidase 4 (GPX4), leading to the release of damage-associated molecular patterns and thereby amplifying the anti-tumor immune response. This study represents the first instance of integrating arsenene's apoptosis-inducing properties with vanadium's ferroptosis-enhancing effects, providing a synergistic approach to improving the immunotherapeutic response and offering a potential strategy for enhancing TNBC prognosis. Statement of Significance Triple-negative breast cancer (TNBC) exhibits resistance to immunotherapy due to its highly immunosuppressive tumor microenvironment. In this study, tumour-responsive Arsenene-Vanadene nanodots (AsV) were developed to induce a synergistic effect by triggering apoptosis and ferroptosis through microenvironment-specific mechanisms. The arsenic component generates cytotoxic trivalent arsenic, promoting apoptosis while binding to cysteine, thereby reducing GSH synthesis. Simultaneously, vanadium initiates lipid peroxidation through Fenton-like reactions and disruption of the glutathione/GPX4 axis, further amplifying ferroptotic cell death. This dual-action system transforms tumor cell debris into immune-stimulating signals while circumventing conventional immunotherapy limitations. As the first strategy integrating arsenic-induced apoptosis with vanadium-enhanced ferroptosis, this approach provides a mechanistic framework to overcome TNBC immunosuppression through coordinated cell death pathways, demonstrating potential for precision nanomedicine applications.

As a hazardous pollutant, ammonia (NH 3 ) poses significant environmental and health risks. This study synthesized multifunctional NH 3 -adsorption biochar through co-pyrolysis of food waste digestate (FWD) and wood waste (WW), focusing on the physicochemical properties of derived biochar and their contributions to NH 3 adsorption. The optimized conditions enabled biochar with tunable production yields (25.8-67.9 wt%) and enhanced porosity (specific surface area reaching up to 331 m 2 /g). Thermogravimetric mass spectrometry combined with multiple spectral analyses uncovered a three-stage devolatilization process and tracked the structural transformations of the resultant biochar. Additionally, acid washing was applied to selectively remove surface-bound metallic salts from high-ash-content FWD-WW co-pyrolysis biochar, thereby liberating more active sites. Langmuir and Freundlich adsorption equilibrium models were systematically applied to evaluate the NH 3 adsorption performance of the biochar with/without modification, revealing a maximum adsorption capacity of 124.2 mg/g at 25 °C (1 bar). Adsorption kinetics and thermodynamics indicated that NH 3 adsorption occurred predominantly via spontaneous physisorption, enhanced by chemisorption at Brønsted acid sites (-COOH/Si-OH) and Lewis acid sites (Fe 3+ /Al 3+ ). This study demonstrates a waste-to-adsorbent strategy through controlled co-pyrolysis and surface engineering for sustainable air pollution mitigation.

LiNi0.8Co0.1Mn0.1O2 (NCM811) is considered a cathode material with great commercial potential. However, Li/Ni mixing, residual lithium compounds, and side reaction limited the popularity of Ni-rich batteries. Thus, a simple strategy is employed to realize a comodification of Na+ and Y3+. As demonstrated in the XPS results, the residual lithium compounds (Li2CO3/LiOH) and side reaction products are inhibited. The capacity retention rate of the modified NCM811 is 86.4% after 300 cycles at 1C, 34.5% higher than that of the pristine. Na+ expands the space of the Li+ slab, thereby reducing the charge transfer resistance and inhibiting the mixed discharge of cations. Meanwhile, Y3+ decreased the lattice along c-axis to restrict the movement of cations (Ni2+) into the Li site, with improving the exchange of Li+. The formed LiYO2 coating layer restrains the direct contact between the electrolyte and the electrode material so that side reactions are inhibited, reducing the electrochemical resistance.
