Poor room-temperature ionic conductivity and lithium dendrite formation are the main issues of solid electrolytes. In this work, rod-shaped alumina incorporation and graphite coating were simultaneously applied to poly (propylene carbonate) (PPC)-based polymer solid electrolytes (Wang et al., 2018). The obtained alumina modified solid electrolyte membrane (Al-SE) achieves a high ionic conductivity of 3.48 × 10 −4 S/cm at room temperature with a wide electrochemical window of 4.6 V. The assembled NCM622/Al-SE/Li solid-state battery exhibits initial discharge capacities of 198.2 mAh/g and 177.5 mAh/g at the current density of 0.1 C and 0.5 C, with the remaining capacities of 165.8 mAh/g and 161.3 mAh/g after 100 cycles respectively. The rod-shaped structure of Al 2 O 3 provides fast transport channels for lithium ions and its Lewis acidity promotes the dissociation of lithium salts and release of free lithium ions. The lithiophilic Al 2 O 3 and Graphite form intimate contact with metallic Li and create fast Li + conductive layers of Li-Al-O layer and LiC 6 layer, thus facilitating the uniform deposition of Li and inhibiting Li dendrite formation during long-term cycling. This kind of composite Al-SE is expected to provide a promising alternative for practical application in solid electrolytes.

Dibenzo[b,d]thiophene and dimethoxybenzene bridges tune viologen charge transport. • DMBBH delivers 72.0% optical contrast and 183.90 cm 2 /C coloration efficiency. • DMBBH retains 61.8% optical contrast after continuous cycling for 10000 s. Organic electrochromic materials have shown considerable potential for applications in smart windows, biosensors, and energy-storage devices owing to their tunable molecular structures, facile preparation, and rich color variation. Conventional viologen compounds are susceptible to over-reduction in their reduced states, which induces irreversible structural changes and limits their application in bifunctional electrochromic-photoluminescent devices. Viologen molecules possess excellent structural designability, and their optical and electrochemical properties can be precisely modulated by modifying substituent structures, counterions, and conjugation lengths, giving them irreplaceable advantages in electrochromic applications. In this study, an aromatic-bridging strategy was adopted, in which dibenzo[b,d]thiophene and dimethoxybenzene units were introduced between pyridine rings to modulate molecular conjugation and charge transport, while hydroxyhexyl side chains were incorporated to improve molecular solubility and intermolecular interactions. The experimental results demonstrate that the successfully prepared 4,4′-(2,5-dimethoxy-1,4-phenylene)bis(1-(6-hydroxyhexyl)pyridin-1-ium) dibromide (DMBBH) exhibits outstanding performance. DMBBH enables a reversible transition from a transparent state to a deep-red state, with an optical contrast of ΔT = 72.0%, a high coloration efficiency of η = 183.90 cm 2 /C, coloration (τ c )/bleaching (τ b ) response times of 9.5 s and 51 s, respectively, and an optical contrast that remains at 61.8% after 10000 s of cycling. This work demonstrates the key role of aromatic bridging structures in stabilizing the excited states of viologen molecules and optimizing charge-transport pathways, providing a new design strategy for future high-performance bifunctional organic optoelectronic devices. DMBBH-based electrochromic devices show reversible transparent-to-deep-red switching, with ΔT = 72.0%, η = 183.90 cm 2 /C, τ c /τ b = 9.5/51 s, and stable operation over 10000 s.

Bio-derived lignin nanospheres act as active interfacial regulators in W 18 O 49 . • Spectroscopy supports electronic and oxygen-vacancy-related defect modulation. • Physical-mixing controls support the importance of in situ interface formation. • W 18 O 49 /LNS shows 76.1 ± 0.8% modulation, 7 ± 1 s bleaching, and improved retention. Designing robust organic-inorganic interfaces is essential for resolving the kinetics-stability trade-off in electrochromic (EC) smart-window materials. Here, bio-derived lignin nanospheres (LNS) are used as active interfacial regulators for defect-rich W 18 O 49 nanowires. Coordination-associated interactions between LNS and W 18 O 49 are accompanied by changes in the local electronic environment and oxygen-vacancy-related defect states. The optimized W 18 O 49 /LNS film delivers an optical modulation of 76.1 ± 0.8% at 654 nm, a coloration efficiency of 31.7 ± 1.1 cm 2 C −1 , and a bleaching time of 7 ± 1 s, together with improved cycling retention. Semi-quantitative W L 3 -edge X-ray absorption analysis indicates a decrease in the estimated average W oxidation state from 3.29 to 2.89. Operando FT-IR spectroscopy and DFT calculations reveal bias-induced changes in the interfacial redox and solvation environment, while ESR and electrochemical kinetic analyses support defect modulation and an increased surface-controlled contribution. These findings establish bio-derived interfacial regulation as a promising strategy for defect-rich functional oxide nanocomposites.

● Highly dispersed Co 2 P anchored onto PEI-stabilized N-rGO layers. ● Gas production rate of 517 mL g −1 h −1 with 100% H 2 selectivity. ● Uniform heterointerface with highly accessible interfacial sites. ● Energy barrier reduction by optimized electronic modulation of interfacial Co δ+ . Heterointerface engineering is an effective strategy for constructing strong metal–support interactions and regulating the electronic structure of metal active centers. In this study, the two-dimensional (2D) architecture of N-doped reduced graphene oxide (N-rGO) was employed to construct a uniform and highly accessible heterointerface with Co 2 P nanoparticles, thereby optimizing the electronic structure of Co 2 P for efficient hydrogen production from liquid-phase formic acid (FA). Specifically, polyethyleneimine (PEI) was introduced to stabilize the layered structure of rGO during calcination by intercalating between GO sheets, along with interacting with functional groups on GO via electrostatic interactions and hydrogen bonding. Meanwhile, PEI served as a nitrogen source to promote N doping of rGO and increase effective anchoring sites, such as pyridinic N. The resulting Co 2 P@N-rGO (PEI&phen) catalyst simultaneously achieved high Co 2 P dispersion, exposed interfacial sites, and efficient electron transfer, thereby exhibiting excellent FA dehydrogenation activity with a gas generation rate of 517 mL g −1 h −1 and H 2 selectivity of 100%. This activity was significantly higher than that of the PEI-free counterpart, in which the N-rGO structure was severely damaged, and also exceeded the activities reported for some noble-metal catalysts (e.g., Pd/C, Pt/C) and single-atom cobalt catalysts. XPS characterization and density functional theory (DFT) calculations demonstrated that the abundant Co–N interfacial sites in Co 2 P@N-rGO (PEI&phen) induced interfacial charge redistribution and optimized the electronic structure of Co 2 P species. In situ DRIFTS and DFT calculations confirmed that FA dehydrogenation over this catalyst proceeded through a formate (HCOO*) pathway, while the construction of the Co 2 P/N-rGO heterointerface significantly lowered the energy barrier of the key reaction step, thereby enhancing the catalytic activity.

An ionic liquid-grafted catalyst, denoted as IL@MIL-101-NH 2 , was synthesized by introducing a novel functionalized bis-imidazolium ionic liquid containing carboxyl groups into the MIL-101-NH 2 (Cr) using a simple one-step method. The structural features of the catalyst were characterized by FT-IR, XRD, XPS, BET, SEM and so on, and its catalytic performance in the cycloaddition reaction of carbon dioxide (CO 2 ) with propylene oxide (PO) to propylene carbonate (PC) was investigated. The results demonstrated that IL@MIL-101-NH 2 exhibited excellent catalytic activity. Under the conditions of 110 °C, 2 MPa, 3 h, and a catalyst loading of 3.0 wt%, a PO conversion of 95.1% and a PC selectivity of 98.7% were achieved. The superior catalytic performance of IL@MIL-101-NH 2 was attributed to the synergistic effect among the Cr 3+ metal active centers, nucleophilic Br − species and hydrogen-bond-donating –COOH groups. In addition, the catalyst maintains good catalytic performance after four consecutive cycles, indicating its favorable stability and promising application potential. Graphical

The rapid detection of polyethylene terephthalate (PET) nanoplastics (PET NPs) is hindered by their low concentration, high mobility and lack of a distinguishable interface with other nanoplastics. In this study, we developed an SnS 2 @MoS 2 /APTES amino-functionalized photoelectrochemical sensor capable of detecting PET NPs with high specificity. The SnS 2 @MoS 2 heterojunction synthesized via in situ hydrothermal synthesis and the APTES self-assembled amino-functionalized interface enable PET NPs to interact with amino-functionalized interface at multiple sites through oxygen-containing groups such as ester groups, carbonyl oxygen and ether oxygen. The sensor exhibits a detection range of 0.5-800 μg mL −1 for PET NPs, with a detection limit of 0.17 μg mL −1 . DFT calculations further indicate that the PET-APTES system exhibits a lower adsorption energy (−1.37 eV) and a more significant interfacial charge rearrangement, demonstrating that the APTES amino siloxane interface exhibits a polymer structural selectivity toward PET. Furthermore, this PEC sensor exhibits good recovery rates (96.04%-102.76%) in practical water samples such as seawater, bottled water and tap water. It provides a new method for interface recognition and signal conversion for the specific PEC detection of PET nanoplastics.

PC coatings with structural colors are fabricated by embedding method through cooperative DSDV process. • Different from traditional strategies, the embedding method adopts a new “coating before assembly” strategy. • Conformal PC coatings are prepared on 33 substrates, including boards, fabrics, inorganics, metals, plastics, and rubbers. • The embedding method works for the polystyrene-arylate, alkyd, polyurethane, and polyvinyl alcohol-based PC coatings. Colloidal photonic crystal (PC) coating has wide application in automotive manufacturing, textile dyeing, packaging and printing, cosmetics and personal care, and anti-counterfeiting materials. However, the traditional methods based on strategies of “coating after assembly” and “coating along with assembly” show poor compatibility with the substrates and polymer components. Here, a new method based on the embedding of colloidal crystals into the precoated polymer layer was developed to prepare durable PC coatings with bright and uniform structural colors. This embedding method pioneers a new synthetic strategy, which is “coating before assembly”. The coating formation is proved to follow the DSDV mechanism, which refers to the cooperative “polymer dissolution”, “liquid photonic crystal (LPC) sinking”, “polymer diffusion”, and “solvent volatilization” processes. The embedding method successfully produces conformal SiO 2 /(PS-PMMA) PC coatings with fine surface features on 33 substrates, including fibrous boards, fabrics, inorganics, metals, plastics, and rubbers, and it also works for the fabrication of alkyd resin, polyurethane, and polyvinyl alcohol-based PC coatings, which will accelerate its practical implementation in various scenarios. An embedding method following the “Coating before Assembly” strategy is developed to prepare durable PC coatings with bright and uniform structural colors. This method yields conformal coatings on diverse substrates, including fibrous boards, fabrics, inorganic materials, metals, plastics, and rubbers. Additionally, it is applicable to coatings based on acrylic resin, alkyd resin, polyurethane, and polyvinyl alcohol. Download: Download high-res image (100KB) Download: Download full-size image

van der Waals (vdW) interactions play a crucial role in various fields, including self-assembly and electronic devices. However, precisely manipulating intermolecular vdW interactions at the single-molecule level to develop supramolecular transistors remains a central challenge. In this study, we report a supramolecular transistor via electrochemical manipulation of a single molecule to a vdW dimer in nickel bis(dithiolene) (NBTE) junctions using the electrochemical scanning tunneling microscopy break-junction technique. Conductance measurements reveal that NBTE remains monomeric under positive potential but forms negatively charged vdW dimers under negative potential. This single-electron redox-driven transition triggers a ∼700-fold increase in conductance and shifts the transport path from in-plane to cross-plane. Theoretical calculations confirm that the dimer is stabilized predominantly by vdW interactions, further enhanced by electric fields, thereby enabling fine regulation of the transistor’s conductance. This work demonstrates the first single-electron supramolecular transistor dictated by intermolecular vdW forces, offering a promising strategy for low-power vdW electronics.

A two-step strategy of electrosynthesis-solvothermal process builds NiMo/G composites with Ni-O-Mo bridges. • Mo acts as interfacial electron pump, locking Ni in high-valent state. • Electron modulation lowers γ-NiOOH formation barrier by ∼150 mV and CH 3 O → CH 2 O step to 0.46 eV. • NiMo/G delivers 320.6 ± 5.2 mA cm −2 and 15,638.9 ± 254.1 mA mg Ni −1 , enabling low-overpotential formate pathway. The intrinsic instability of the active γ-NiOOH phase severely limits the performance of nickel-based electrocatalysts for the methanol oxidation reaction (MOR). Herein, we report a Mo-induced interfacial electron pump strategy to stabilize the γ-NiOOH lattice and boost MOR efficiency. Via a distinctive two-step strategy of electrolysis and subsequent solvothermal reaction, we construct NiMo/graphene (NiMo/G) composites rich in Ni-O-Mo interfaces, where Mo centers continuously withdraw electrons from adjacent Ni sites, functioning as efficient electron sinks. This precise electronic modulation lowers the thermodynamic barrier for γ-NiOOH formation by ∼150 mV and optimizes the adsorption energetics for intermediates, reducing the energy barrier of the rate-determining *CH 3 O → *CH 2 O step from 0.68 to 0.46 eV, thereby directing the reaction along a low-overpotential formate pathway. Consequently, this optimized NiMo/G catalyst achieves exceptional area activity of 320.6 ± 5.2 mA cm −2 and mass activity of 15,638.9 ± 254.1 mA mg Ni −1 , respectively. This work establishes interfacial electron pump engineering as a general and powerful strategy for stabilizing high-valent active phases in advanced energy conversion and storage technologies.

Capturing CO 2 at scales have drawn increasing attention to addressing climate change and meeting global carbon targets. However, current CO 2 capture strategies face critical tradeoffs in terms of selectivity, regeneration energy, and cost-effectiveness. Here, we present a net-like colloid that is formed by the self-assembly of simple molecules, e.g., some organic ligands of metal–organic frameworks, in water. They have reticular characteristics under cryo-scanning electron microscopy and in particular, form a skeleton/micro-pool structure. We demonstrate the thermal response of the reticular structure, which declines with elevated temperatures, brings the colloidal peculiar CO 2 absorption-desorption behaviors. Specifically, they absorb CO 2 with high capacity at lower temperatures and release high-pressure gases with thermal input at higher temperatures (with over half of regeneration efficiency under 80 °C and 5 bar), enabling a high gas capacity but a low regeneration penalty. The construction of net-like structure has achieved excellent separation performance over gases, including CH 4 and N 2 (with a maximum selectivity of 1539 and 7609, respectively). Further, our finding to create a novel thermal-responsive colloid is scalable and feasible in large-scale applications, and can expand the field of colloid science significantly.

Metal-organic frameworks (MOFs) are promising electrochromic materials owing to their rapid response and multicolor switching capabilities. However, their performance in thin-film configurations is often limited by slow switching speeds and insufficient optical contrast. In this study, a conjugated biphenyl-based ligand, 4,4′-dihydroxy-3,3′-biphenyldicarboxylic acid (DHBDC), was employed to synthesize Co/Ni MOF films directly on fluorine-doped tin oxide (FTO) substrates via a one-pot solvothermal method. The introduction of Co 2+ and the Ni/Co molar ratio are identified as decisive factors for steering the mesoscopic architecture, enabling precise tuning from agglomerated particles to a well-aligned nanorod arrays. The film fabricated with an equimolar (1:1) Ni/Co ratio at 150 °C delivers optimal performance, exhibiting a high optical contrast of 84% at 900 nm with rapid coloration/bleaching times of 2.9 s and 7.0 s, respectively, alongside good stability over 1000 cycles. Electrochemical analysis confirms that this optimal morphology yields the highest charge transport kinetics and Li + diffusion coefficient. This work provides a viable strategy and fundamental insights for developing high-performance MOF-based electrochromic materials.

Intelligent electrochromic systems that integrate energy storage with optical feedback are increasingly sought after to meet the demands of global energy transition and the burgeoning field of flexible electronics. Yet, the performance and reliability of flexible zinc-based electrochromic energy storage devices (EESDs) are often compromised by the limitations of conventional electrolytes, including poor interfacial stability, liquid leakage, and inadequate mechanical robustness. Herein, we report a high-performance flexible EESD based on a Prussian blue–zinc (PB–Zn) chemistry, enabled by a scalable blade-coated PB cathode and a quasi-solid-state electrolyte (QSSE) incorporating a semi-interpenetrating polymer network (semi-IPN) of poly(vinylidene fluoride- co -hexafluoropropylene) (PVDF-HFP) and ethoxylated trimethylolpropane triacrylate (EOTMPTA). The device delivers a high optical modulation of 74.49%, a coloration efficiency of 189.77 cm 2 C −1 , and outstanding cycling stability with 93.72% retention after 10,000 cycles, attributed to a stabilized electrode–electrolyte interface enabling highly reversible zinc electrochemistry. Moreover, the system demonstrates efficient self-powered operation when integrated with a solar cell (SC), highlighting its potential for energy-autonomous smart windows. Overall, this work establishes a material–interface co-design strategy that provides a promising pathway toward durable, high-performance, and self-sustaining electrochromic smart windows.
