In the field of marine antifouling, the importance of hydrogel marine coatings with high adhesion, anti-protein properties, and anti-fouling performance for marine pollution prevention should not be underestimated. While water gels have received widespread attention for their hydrophilic and eco-friendly characteristics, the inadequate adhesion and mechanical properties of traditional hydrogels limit their broader applications. In this study, a unique mussel-mimicking structure provides the coating with robust adhesion to the substrate material. The incorporation of methoxy methylated melamine-formaldehyde resin enhances the gel’s resistance to swelling and its mechanical properties, whereas tannic acid and cuprous oxide possess excellent adhesive properties and resistance to proteins and fouling. A comprehensive coating formulation exhibits superior resistance to protein and particulate contamination. This study paves the way for the development of highly adhesive marine biomaterials, which is of vital importance for the sustainable development of marine biomaterials. Graphical abstract

The novel hypercross-linked porous ionic polymers combine the advantages of ionic liquids, hydrogen-bond donors and hypercross-linked polymers. In this regard, imidazolium-based ionic liquids with different hydrogen-bond donors (hydroxyl and carboxyl groups) were grafted on hypercross-linked polymers by taking advantage of the easier functionalization of ionic liquids. With the introduction of ionic liquids, the CO 2 adsorption capacity of HCP-CH 2 IL-COOH was increased to 13.86 wt % (273 K, 1 bar). The catalytic performance of HCP-CH 2 IL-OH and HCP-CH 2 IL-COOH with containing hydrogen-bond donors was found better than that of HCP-CH 2 IL-Et without hydrogen-bond donor. In addition, HCP-CH 2 IL-OH showed the highest CO 2 conversion efficiency after 48 h with a high yield (up to 94%) at room temperature and pressure due to high specific surface area, high CO 2 adsorption capacity and the catalytic activity of ionic liquid, which achieved efficient CO 2 conversion by metal-free catalytic system under mild conditions. The TON and TOF values were found to be up to 292 and 6 h −1 , and the efficiency was comparable to that of the current metal-free heterogeneous catalytic systems. In addition, the catalyst can efficiently convert different terminal epoxides and show good universality. More interestingly, the catalytic activity of this catalyst was retained after five cycles, which endorse its recycling stability.

Upgrading fatty acid derivatives is a promising route to sustainable diesel and jet fuels, but conventional processes require high temperature, pressure, and large H₂ input, while contaminants in waste oil deactivate catalysts, demanding costly purification. Here, we present an integrated electrochemical strategy combining anodic decarboxylation, cathodic proton reduction, and olefin hydrogenation in one reactor, upgrading fatty acid derivatives to long-chain alkanes under mild conditions (60 °C, 1 atm) without external hydrogen. A high alkane yield of 88.9% is achieved and the reported performance is competitive. Experiments and calculations reveal that fatty acid chain length governs product yield and distribution by influencing –H departure and C γ –C β –COOH bond cleavage barriers. This approach shows high activity and selectivity toward diverse feedstocks, including unsaturated fatty acids, esters, mixtures, crude acids, and waste oils. Powered by solar energy, approximately 40 g of long-chain alkanes are produced in a 1 L reactor, highlighting its scalability and potential for green fuel synthesis.

Organic electrochemical transistors (OECTs), endued with processing and memory functionalities, present a remarkable potential for neuromorphic electronics. However, integrating processing and memory cores for neuromorphic systems is complicated by heterogeneous material compatibility and device architecture constraints. Here, we demonstrate a versatile regionally controlled ion-doping strategy for modulating the operational mode of OECTs between high-performance computing and non-volatile memory, without varying the materials or operating conditions. The key to this method is the use of inkjet-printed electrolytes with programmable 3D architectures, which can be precisely deposited onto the OECT channel, achieving a tunable thickness ranging from 100 nm to several tens of micrometers. By engineering the electrolyte’s spatial structure, we demonstrate two complementary OECT configurations: ion-rich OECTs with multilayer electrolytes achieve high stimulus-resolution capability of 1 ms for dynamic computation, and ion-deficient OECTs with single-layer electrolytes establish stable ion-trapping memristive states (300 s retention). Moreover, the integration of ion-rich and ion-deficient OECTs enables a neuromorphic circuit capable of simultaneous encoding and storage of alphanumeric information. This study presents a simple yet effective strategy that overcomes material compatibility constraints and simplifies circuit design, paving the way for highly integrated neuromorphic systems based on OECTs.

African swine fever (ASF) is an acute hemorrhagic disease in pigs caused by the African swine fever virus (ASFV), which has a high mortality rate and brought great damage to global pig farming industry. At present, there is no effective treatment or vaccine to combat ASFV infection, so early detection of ASFV has become particularly important. Therefore, the PDMS/chitosan/MPMs composite film was proposed to detect ASFV P72. PDMS mixed with chitosan particles were used to provide biological modification sites for the ASFV P72 antibody, which simplified the functional modification process. The specific binding of antigen and antibody leads to the mechanical deformation of the composite film, which was observed through optical method to change the microsphere spacing. The polystyrene microsphere (PMs) spacing changes were acquired by simply measuring the diameters of the Debye ring diffracted by the PDMS/chitosan/PMs with a simple laser pointer. The conductive layer formed by AgNWs realize the transformation of biological signals to electrical signals. By conjugating PMs with Fe 3 O 4 nanoparticles (MPMs) and applying a magnetic field, a magnetic-stress-electric coupling system has been constructed, which amplifies the deformation of the composite film and enhances the sensitivity of the flexible film. The experimental results showed that the flexible film has wide linear range of 10 ng/mL–100 μg/mL, and the optimal detection limit (LOD) is 0.059 ng/mL, which was about one order of magnitude lower than that without magnetic field. In addition, the flexible film showed a good stability, specificity, and selectivity. Graphical

On-surface synthesis recently enabled access to generate a series of cyclo[ n ]carbons (C n , up to C 26 ) via delicately designed precursors. However, for larger cyclocarbons, synthesis of the corresponding precursors is being challenged. Here, we report another strategy for synthesizing larger cyclocarbons via the coupling and ring-opening reactions from smaller ones. We chose C 10 as the precursor, and induce the coupling and ring-opening reactions via tip manipulation to successfully generate C 20 and C 30 . Bond-resolved atomic force microscopy imaging unambiguously reveals the polyynic structure of C 30 , aligning with theoretical prediction. This approach establishes a new pathway to access larger cyclocarbons, and potentially enables controlled polymerization of cyclocarbons.

The creation of thermally conductive pathways in polymers is crucial for achieving high thermal conductivity in composites. In this study, a novel ultrafine and ultrathin-walled boron nitride hollow nanotube (BNNT) was employed to fabricate two types of 3D-BNNT/EP composites, 3D-BNNT/EP-p and 3D-BNNT/EP-f, prepared via powder hybrid compression molding and ice-templating methods, respectively. The experimental results show that the 3D-BNNT/EP-p composites exhibit high performance at high BNNT loading (55.87 wt%). The in-plane thermal conductivity reached 1.091 W/(m K), representing a 590% enhancement over pure epoxy resin (0.185 W/(m K)), while the T 60% decomposition temperature increased by 63 °C, indicating superior thermal conductivity and stability. Practical application tests reveal that this material can reduce the maximum operating temperature of LED devices by 11.3 °C, demonstrating its heat dissipation advantages. In contrast, the ice-templated composites showed higher filler efficiency at low BNNT loading (10.18 wt%), achieving an 89% improvement in in-plane thermal conductivity. However, their 3D network contained CMC-Na binder, leading to discontinuous thermal pathways and only a 24 °C improvement in thermal stability. Dielectric property measurements confirmed that both types of composites maintained the low-dielectric characteristics of the epoxy matrix, with the compression-molded samples exhibiting more stable dielectric loss behavior at high frequencies. Finite element simulations verified the thermal enhancement mechanism of 3D-BNNT networks and highlighted the impact of processing methods on performance. These findings provide both a theoretical foundation and practical guidance for the selection and design of high-performance thermal management materials in advanced electronic and optoelectronic devices.

Li metal is highly sought after as a negative electrode material due to its high specific capacity and low electrode potential. However, the brittle solid electrolyte interphase and undesirable coulombic efficiency have severely hindered its commercial application. Here we propose a formation mechanism of stable solid electrolyte interphase based on the de-solvation of heteroalkali cations rather than the simple electrostatic shielding effect. Cesium trifluoroacetate (CsTFA), characterized by high electron-donor anion and weak solvent-binding heteroalkali cation, was incorporated into commercial electrolytes to foster an inorganic-rich solid electrolyte interphase. The de-solvation of absorbed Cs + dominates the initial solid electrolyte interphase formation on the Li surface. Simultaneously, the preferential reduction of TFA - promotes the enrichment of LiF within the solid electrolyte interphase. Owing to the synergistic effect of CsTFA, Li | |Cu half cells deliver a high CE of 99.77%, and Li | |LFP full cells exhibit satisfactory stability over 300 cycles with a 94.3% capacity retention at a negative/positive electrode capacity ratio of 1.36. Moreover, the added CsTFA in conventional ester electrolyte demonstrates improved stability of Li | |NCM811 full cells with an 80% capacity retention over 222 cycles at a negative/positive electrode capacity ratio of 1.

Background Aligned nanofiber scaffolds have shown great promise in promoting neurite orientation and elongation, making them a key design strategy in peripheral nerve tissue engineering. However, most current designs lack biochemical specificity and long-term stability, limiting their regenerative efficacy. Results Herein, we developed structurally aligned nanofiber yarns (NFYs) scaffold conjugated with laminin via covalently incorporated N-hydroxysuccinimide (NHS) ester groups. The NHS-functionalized NFYs were fabricated using a dry–wet electrospinning approach based on a copolymer of N-succinimidyl acrylate (AA-NHS) and N-isopropyl acrylamide (NIPAM), blended with polycaprolactone (PCL) and multi-walled carbon nanotubes (MW-CNTs). This scaffold integrates both topographical and biochemical guidance, forming a stable biomimetic extracellular matrix (ECM) interface that supports long-range neurite extension. Laminin-conjugated NFY–NHS scaffolds significantly enhanced neurite alignment and elongation in PC12 cells and dissociated dorsal root ganglion (DRG) neurons, while simultaneously reducing excessive neurite branching. In DRG explant models, the scaffolds supported fasciculated neurite bundles that extended unidirectionally along the fiber orientation, mimicking native nerve architecture. These findings demonstrate that laminin-conjugated aligned NFYs provide a dual-function platform for guiding neurite outgrowth and regulating branching morphology. Conclusions This strategy offers a promising approach for engineering physiologically relevant neural scaffolds with applications in peripheral nerve regeneration and in vitro nerve model development. Graphical Open in a new tab Laminin-conjugated aligned nanofiber yarns (NFYs) provide dual topographical and biochemical guidance for directed neurite outgrowth. NHS-activated NFYs stably immobilize laminin, promoting long-range axon elongation and reducing aberrant branching, enabling biomimetic nerve regeneration.

Sigma Non-Opioid Intracellular Receptor 1 (SigmaR1) is a member of the sigma family of receptors that interacts with a variety of psychotomimetic drugs and is involved in a wide range of cellular and physiological functions. Despite its increasing importance in human physiology and disease, the subcellular localization of SigmaR1 and its molecular function remain poorly defined. Using endogenous tagging and cell fractionation, we show that SigmaR1 is a type II integral ER membrane protein that is specifically enriched at ER sheets. A short region at the N-terminus of SigmaR1 promotes its ER-sheet localization. Importantly, our biochemical studies demonstrate that SigmaR1 directly interacts with components of the translocon complex including TRAPα and Nicalin. In addition, we found that a β-barrel at the C-terminal of SigmaR1 binds phosphatidylcholine (PC), and the binding of PC strengthens the association of SigmaR1 with the translocon complex. SigmaR1 knockout systematically impaired cellular protein and lipid homeostasis, resulting in accumulation of lipid droplets in hepatocytes. Collectively, we propose that SigmaR1 is an auxiliary translocon factor that binds lipids to regulate protein and lipid droplet homeostasis, which may underlie the broad and vital roles of SigmaR1 in physiology and disease.

Due to its benefits of low energy consumption, minimal environmental pollution, and simple operation, membrane technology is considered a carbon capture technology with extensive application possibilities. In this study, the ultraviolet cross-linking method is used to inhibit crystallization of polymers with a molecular weight of less than 1500 and enable polyethylene oxide (PEO) to form a rubbery polymer matrix. This approach avoids membrane separation defects and low CO 2 solubility caused by high crystallinity. The hydroxyl-rich surface of layered double hydroxide (LDH) is used to provide the CO 2 -philic site in the form of “docking station-like” by introducing amino groups with a strong affinity for CO 2 , and forming a dual facilitated transport channel through the nanosheet interlayer channel and the presence of bound water to strengthen the reaction mechanism of the membrane. Based on the coupling of solubility-diffusion and facilitated transport mechanisms, the optimal separation performance is achieved when the NH 2 -PDA-LDH doping is 0.4 wt%, with a CO 2 permeability of 572.4 Barrer and a selectivity of up to 60.5. The interlayer fast transport channels result in a maximum permeability of 3982 Barrer in the wet state. Graphical
