Cadmium sulfide (CdS), as a potential photoelectrochemical (PEC) photoanode candidate, generally exhibits unsatisfactory hydrogen generation because of the serious recombination of charge carriers and photocorrosion. In this work, a feasible p-n heterostructure CdS/AgVO 3 nanorod arrays (NRAs) photoanode was fabricated by modifying n-type CdS nanorod arrays with p-type AgVO 3 nanoparticles for enhancing PEC hydrogen evolution property of CdS NRAs photoanode. In this p-n heterostructure CdS/AgVO 3 nanorod arrays photoanode, AgVO 3 with narrower band gap not only distinctly heightens the visible light absorption ability of CdS, but also significantly integrates with CdS to establish charge transfer path at CdS and AgVO 3 interface. The built-in electric field of the p-n junction improves the separation and transfer efficiency of photogenerated electrons (e − ) and holes (h + ). The CdS/AgVO 3 NRAs photoanode achieves an evident hydrogen evolution rate of 165.05 μmol cm −2 h −1 , higher than that of bare CdS (121.85 μmol cm −2 h −1 ) NRAs photoanode. This work offers an effective scheme to fabricate photoanode for efficiently turning the solar energy into a green and clean energy.

In this research, we introduce a novel and efficient approach for enhancing both the antibacterial efficacy and resistance to protein fouling of nanofiltration (NF) membranes, marking the first report of a method capable of concurrently addressing these critical membrane performance parameters. After traditional interface polymerization (IP), NF membranes were post-treated by the antibacterial N-(3-Aminopropyl)-imidazole (ANPI) which can be grafted on the membrane by its amino group reacting with rest acyl chloride in IP on the surface. After parameter optimization of the ANPI concentration, the modified membrane NF-12 demonstrated up to 99% antibacterial activity against two representative pathogens, Escherichia coli and Staphylococcus aureus . Except for this, due to the zwitterionic effect, the modified membrane achieved a remarkable 68.7% enhancement in water flux and the recovery rate of BSA cyclic pollution reached 97.5%. From mechanism analysis, it can be proposed that the post-grafted ANPI brought antibacterial properties to the NF membrane, which was able to kill bacteria attached to the membrane surfaces. Also, the imidazole protonation introduced positive charges to the NF membrane surface, mixing with negative charges produced by acyl chloride hydration, which produced the zwitterionic effect and facilitated the formation of a robust hydrophilic hydration layer, thereby significantly diminishing the adhesion of contaminants.

Artificial synaptic devices are the basic composition units for neuromorphic computing processors that realize massive parallel computing. However, the n-type organic transistors have failed to achieve good performance as an artificial synaptic device for neuromorphic computing until now. Here, a vertical three-terminal n-type organic artificial synapse (TNOAS) using a lithium ion-based organic dielectric and the n-type donor–acceptor (D–A) conjugated polymer-naphthalene-1,4,5,8-tetracarboxylic-diimide-thiophene-vinyl-thiophene (NDI-gTVT) as the channel is proposed. The TNOAS achieves nonvolatile conductance modulation with high current density operation (≈10 KA cm −2 ) at low voltage and mimics the basic functions of biological synapses, such as long-term synaptic plasticity and paired-pulse facilitation. The minimum energy consumption of a response event triggered by a single action potential is 6.16 pJ, which can be comparable with p-type counterparts. Moreover, simulation using handwritten digital datasets exhibit a high recognition accuracy of 94%.

The integration of soft, conformable components and rigid microelectronics or devices is a critical frontier in stretchable hybrid device development. However, engineering interconnects capable of tolerating high-stress concentrations and preventing debonding failures remain a key challenge. Here a stretchable conductive interconnect derived from the liquid metal conductor with supramolecular confinement is reported, capable of reliably connecting soft and rigid parts through a simple “Heat-Press-N-Go” method. Leveraging the dynamic bonding nature of supramolecular polymers, when confined within liquid metal compartments, not only effectively stabilizes the conductive path of the stretchable interconnect, but also offers high adhesion to diverse surfaces, reaching an exceptional electrical stretchability of up to 2800%. As proof of concept, this interconnect is used to assemble wearable devices including reconfigurable stretchable circuits, multifunctional sensors, and on-skin electromyography, exhibiting high signal integrity and mechanical durability. The “Heat-Press-N-Go” chip and circuit integration offers the boundless potential to enhance the adaptability, convenience, and versatility of on-skin and wearable electronics across various applications.

As a low-cost substitute that uses no expensive rare-earth elements for the high-efficiency Cu(In,Ga)(S,Se) 2 solar cell, the Cu 2 ZnSn(S,Se) 4 (CZTSSe) solar cell has borrowed optimization strategies used for its predecessor to improve its device performance, including a profiled band gap and surface inversion. Indeed, there have been few reports of constructing CZTSSe absorber layers with surface inversion to improve efficiency. Here, a strategy that designs the CZTSSe absorber to attain surface modification by using n-type Ag 2 ZnSnS 4 is demonstrated. It has been discovered that Ag plays two major roles in the kesterite thin film devices: surface inversion and front gradient distribution. It has not only an excellent carrier transport effect and reduced probability of electron-hole recombination but also results in increased carrier separation by increasing the width of the depletion region, leading to much improved V OC and J SC . Finally, a champion CZTSSe solar cell renders efficiency as high as 12.55%, one of the highest for its type, with the open-circuit voltage deficit reduced to as low as 0.306 V (63.2% Shockley-Queisser limit). The band engineering for surface modification of the absorber and high efficiency achieved here shine a new light on the future of the CZTSSe solar cell.

While copper complexes intrinsically provide Cu sites for electrocatalytic CO 2 reduction (ECR), their efficacy toward multicarbon products (C 2+ ) remains fundamentally limited by the operational instability of reactive Cu valence states and the inability to synchronously optimize *CO intermediate generation and C-C coupling within symmetric coordination environments. Herein, we judiciously design a single-crystal N, O co-coordinated copper complex (Cu(ICA) 2 ) featuring asymmetric N 2 -Cu-O 2 centers that precisely modulate the electronic structure and local adsorption environment. The Cu-N bonds stabilize partially reduced Cu δ⁺ sites while weakening Cu-O interactions, thus balancing structural integrity with catalytic reactivity. This asymmetric dual-site coordination concurrently hosts distinct *CO intermediates (atop-adsorbed *CO at Cu sites and bridge-adsorbed *CO at Cu-N sites), enabling cooperative C-C coupling into C 2 products. The catalyst achieves a record 69.2 % Faradaic efficiency for C 2 products at 400 mA cm −2 and 57.4 % for C 2 H 4 at 500 mA cm −2 in 1.0 M KOH, rivaling the state-of-the-art Cu-based complexes. In situ characterization and DFT calculations mechanistically corroborate that bridge-adsorbed *CO at Cu-N sites drives energetically favorable hydrogenation and C-C coupling pathways. This work establishes a coordination-asymmetry design principle for constructing robust molecular catalysts capable of efficient CO 2 -to-C 2+ conversion.

Extracellular vesicles, such as Escherichia coli outer membrane vesicles (OMVs), have been widely explored as carriers for contrast agents, yet their application in ultrasound imaging remains limited. In this study, heat-responsive nB-OMVs are developed by loading n-butanol into OMVs (nB-OMVs). Upon heating, the decreased solubility of n-butanol triggered phase separation within the vesicles, resulting in enhanced ultrasound signals, including fundamental, harmonic, and subharmonic components. Experimental results demonstrated that nB-OMVs retained the native morphology of OMVs, along with their tumor-targeting accumulation and tumor growth inhibition capabilities. nB-OMVs injection induces red blood cell extravasation into tumors, under near-infrared (NIR) irradiation, these extravasated RBCs acted as photothermal mediators, generating a localized thermal environment that activated intratumoral nB-OMVs and further amplified the ultrasound signal. In B-mode and contrast-enhanced ultrasound (CEUS) imaging, tumor grayscale intensities increased by 4.6- and 8.5-fold, respectively. This work provides a promising strategy for ultrasound-based tumor imaging using extracellular vesicles.

Van der Waals (vdWs) p–n junctions assembled from 2D materials offer enhanced flexibility for creating versatile electronic and optoelectronic devices, attracting significant interest. However, the lack of reliable methods to produce high-quality p-type 2D semiconductors, especially patterned p-type channels, remains a major challenge for progress in the field. Here, a precise substitutional doping strategy for 2D semiconductors is presented, enabling the production of millimeter-scale WS 2 single-crystal thin films with tailored p-type and n-type properties. This advancement supports the fabrication of high-performance WS 2 -based p-type and n-type field-effect transistor (FET) miniaturized arrays with near-ohmic contact. Building on this progress, a WS 2 van der Waals homojunction p-n array demonstrating distinct anti-ambipolar behavior and excellent rectification characteristics is developed. In self-powered photodetection mode, leveraging the strong coupling of the vdWs homojunction interface, the device achieves an exceptional photovoltaic effect with a high specific detectivity of 3.4 × 10 10 Jones and a fast response time of 400 µs. The development of WS 2 p-n homojunction arrays presents immense potential for advancing next-generation logic electronics and optoelectronic devices, opening new avenues for large-scale industrial applications.

The design of high-performance n-type ionic thermoelectric cells (i-TE cells) tailored for harvesting low-grade thermal energy presents significant challenges. In this study, an n-type i-TE cell exhibiting substantial negative thermopower and a high output energy density is developed by leveraging the synergistic interplay between thermal diffusion within an ionic hydrogel electrolyte and redox reactions at the electrode interface. Specifically, a gel network featuring dual positive groups is synthesized by cross-linking quaternized chitosan and guanidine molecules via glutaraldehyde, with thermal diffusion further enhanced by incorporating crown ether for complexation. Additionally, NiCo(CO 3 )(OH) 2 , a material known for its high hydrophilicity, is utilized as the anode to facilitate rapid ion and electron transfer at the electrode interface. The integration of optimized thermal diffusion within polycationic electrolytes with electrode interface-enhanced ion/electron transport mechanisms significantly improves the sustained output performance and thermoelectric conversion efficiency of the i-TE cell. Notably, the thermopower (Seebeck coefficient) of this n-type i-TE cell achieves a value of −26.04 mV K −1 , and its 2 h output energy density reached 1301.61 J m −2 under a temperature difference (ΔT) of 15 K. These findings offer a novel design paradigm for high-performance n-type i-TE cell.

Commercial Pt/C catalyst in Proton exchange membrane fuel cells (PEMFCs) usually suffers from Pt agglomeration, dissolution, and carbon support corrosion—exacerbated by Pt-catalyzed carbon oxidation. To address these challenges, composite supports combining high stability and electronic synergy with Pt have emerged as a promising solution. Herein, a platinum nanoparticle catalyst supported on a nitrogen-doped titania/carbon composite (Pt NPs/TiO₂-N/C) was successfully fabricated via a two-step hydrothermal method, aiming to optimize both oxygen reduction reaction (ORR) kinetics and durability through regulated support structures and interfacial interactions. Experimental results demonstrate that strong metal-support interactions (SMSI) between Pt and TiO₂-N/C play a critical role. On one hand, SMSI induces electron transfer from the support to Pt, enhances ORR kinetics. On the other hand, this interaction promotes preference nucleation and distribution of Pt on TiO₂-N surfaces, reducing direct Pt-carbon contact and effectively inhibiting Pt-catalyzed carbon corrosion, thereby improving durability. The Pt NPs/TiO₂-N/C catalyst exhibits excellent ORR activity with a half-wave potential of 0.842 V (vs. RHE) and remarkable stability, showing only a 33 mV decay in half-wave potential after 5000 accelerated degradation test cycles. This study validates that precise regulation of metal-support electronic interactions enables synergistic optimization of catalytic activity, stability, providing a theoretical basis and practical strategies for the rational design of high-performance PEMFC catalysts.

The combustion characteristics and energy output properties of solid propellants play a decisive role in rocket engine and propulsion system performance. Particularly for HTPB propellant systems incorporating CL-20 as the high-energy oxidizer, achieving wide-range burn rate regulation and maintaining low pressure exponents constitute fundamental requirements for practical implementation. Through advanced interfacial control methodology, this study successfully constructed two types of aluminum/oxidizer integrated composites (Al@AP and Al@CL-20), while employing precise catalysis to accurately distribute C 3 N 4 burn rate modifiers within the target oxidizer. This innovative approach has demonstrated significant enhancement in aluminum combustion efficiency within the composite propellant system. The strategic incorporation of C 3 N 4 , coupled with the optimized interfacial architecture between fuel and oxidizer components, establishes a new paradigm for performance modulation in solid propellant formulations. Thermal analysis (DSC/TGA) results reveal that both Al@AP/CN and Al@CL-20/CN composites exhibit concentrated exothermic characteristics, yet demonstrate fundamentally distinct heat release profiles. By strategically exploiting these differential energy release features, propellant formulations with tailored interfacial compositions and precisely engineered catalytic sites were developed. The modified propellants displayed markedly different combustion behaviors: the Al@CL-20/CN-based formulation achieved a 33% reduction in pressure exponent ( n =0.18) with significantly enhanced low-pressure burning rates, while the Al@AP/CN-modified system maintained ultra-low burning rates (<5 mm·s -1 ) but with high combustion efficiency across broad pressure ranges with an exceptionally low pressure exponent of 0.23. Complementary analysis of condensed combustion products (CCPs) confirmed substantial improvements in combustion completeness, showing a 78% reduction in micron-sized aluminum agglomerates and significantly refined CCPs particle size distribution. These findings collectively demonstrate that the synergistic combination of interfacial modification and precision catalysis effectively optimizes aluminum combustion efficiency and tunability of burn rate of high-energy HTPB propellants.

Solvent-free nanofluids have attracted increasing attention in tribological applications due to their distinctive load-bearing lubrication mechanisms, which arise from the synergistic interaction between its surrounding corona/canopy structures. In this study, a nanofluid was developed by incorporating N,S-co-doped carbon dots (N,S-CDs) and Jeffamine M2070 into polyimide (PI) matrix. This composite reduced the COF by 61 % (0.15 ± 0.01) and the wear rate by 95 % (3 ± 0.1643) × 10 −6 mm 3 /N·m compared to pure PI. N,S-CDs adsorbed onto friction surfaces via -NH 2 and -COOH groups, enhancing interfacial bonding and raising peak interface temperature by 126 K. This promoted PI fragment graphitization and robust tribofilms formation. M2070 further smoothed the interface by filling voids. The work proposes a “core-resin interface with casing” strategy for tribological materials in high-load, precision applications.
