Atherosclerosis (AS) is characterized by chronic, persistent inflammation and lipid deposition. Macrophage mitochondrial dysfunction leads to excessive release of reactive oxygen species (ROS), exacerbating inflammatory responses and lipid metabolism dysfunction. This study developed a novel nanodrug system (TM@AG NPs) for restoring macrophage mitochondrial function. The system is based on the co-assembly of astaxanthin (AST) and geniposide (Gen), with macrophage membrane coating and triphenylphosphonium (TPP) modification. In vitro experiments demonstrated that mitochondria-targeted TM@AG NPs promoted the repolarization of macrophages from the M1 to the M2 phenotype and suppressed inflammation by efficiently scavenging mitochondrial ROS (mtROS), restoring mitochondrial respiration and energy supply, thereby ameliorating lipid metabolism disorders. In vivo assay using ApoE −/− mice model demonstrated that TM@AG NPs efficiently accumulated in atherosclerotic plaques, significantly reduced plaque area, cleared the necrotic core, and enhanced plaque stability. In summary, this study presents a sequentially targeted strategy for the precise treatment of AS.

Electrocatalytic selective hydrogenation represents a green and atom-efficient synthetic route, yet it remains fundamentally challenging to simultaneously achieve high activity and exceptional selectivity while suppressing competing side reactions, primarily hydrogen evolution and over-hydrogenation. To address this, we fabricate atomically Pd 1 Cu 1 alloy nanoparticles on carbon cloth (Pd 1 Cu 1 /CC) via a facile co-electrodeposition method. The catalyst enables highly efficient and selective electrocatalytic hydrogenation of 2-methyl-3-butyn-2-ol (MBY) to 2-methyl-3-buten-2-ol (MBE) in an aqueous alkaline electrolyte, delivering an MBE production rate of 0.88 mol h −1 g Cat. −1 with 96% selectivity and 92% Faradaic efficiency—performance superior to its monometallic counterparts. The catalyst also demonstrates excellent stability, broad substrate applicability, and promising potential for industrial application. Combined experimental and theoretical results reveal that the Pd 1 Cu 1 /CC catalyst exhibits a lowered activation energy (40.89 kJ mol −1 ), which not only facilitates active *H generation via water dissociation but also weakens the adsorption of MBE due to Cu-induced electronic modulation. This dual mechanism ensures efficient *H supply and prompts product desorption, thereby synergistically boosting selectivity while suppressing both over-hydrogenation and the hydrogen evolution reaction. This work provides insights into the design of advanced electrocatalysts for selective hydrogenation from the perspective of alloy catalyst, contributing to sustainable organic synthesis strategies.

Ceramic membrane separation technology has great potential for the treatment of oily wastewater. However, factors such as low filtration flux, high production costs, and a complicated preparation process hinder its large-scale application. In this study, an asymmetric-structure ceramic microfiltration membrane was successfully prepared using dry-pressing and high temperature co-firing method using alumina whiskers as the membrane layer. The maximum pore size of the ceramic membrane prepared by co-fired at 1450 °C was 0.659 μm, and the pure water flux was 1795L/(m2 ⋅ h ⋅ bar). When treating a 1000 mg/L oil/water emulsion, the ceramic membrane maintained separation flux of 251L/(m2 ⋅ h ⋅ bar) after ten filtration cycles, and the oil rejection efficiency consistently remains above 99%. Moreover, the one-step high-temperature co-firing process will further improve the overall physical and chemical properties of ceramic membranes, providing important reference for improving the application efficiency of ceramic membranes in complex working conditions.

Co-pyrolysis of biomass and plastic enables simultaneous production of biochar, bio-oil, and gaseous products and also offers a pathway for waste recycling and valorization. This research investigates the synergistic effects of co-pyrolysis of cellulose and low-density polyethylene (LDPE) by TG-FTIR and a fixed bed reactor. Kinetic analyses by Flynn-Wall-Ozawa (FWO) and Kissinger-Akahira-Sunose (KAS) models showed that the average activation energy ( E a ) for pyrolysis of cellulose and LDPE individually was 184.1 and 267.4 kJ/mol, respectively, whereas that of 1:1 cellulose/LDPE mixture decreased to 150.4 kJ/mol. Pyrolysis experiment showed that co-pyrolysis suppressed biochar formation while enhancing yields of bio-oil and gaseous products. Co-pyrolysis enriched carbon and removed oxygen in biochar, resulting in maximum graphitization degree and higher heating value (HHV) of 31.51 MJ/kg at 700 °C. Additionally, co-pyrolysis decreased the relative content of light oxygenated compounds in bio-oil. The inhibitory effect of co-pyrolysis on aldehydes, ketones, and acids was maximum at 600 °C. Co-pyrolysis enhanced CH 4 and H 2 formation and suppressed CO 2 and CO. At 700 °C, CH 4 and H 2 proportions peaked to 19.3 vol% and 13.1 vol%, respectively, during co-pyrolysis. This research provides fundamental insights into the synergistic mechanisms of biomass and plastic co-pyrolysis for polygeneration.

Dielectric elastomer actuators (DEAs) are attracting much attention as candidates for next-generation flexible actuation. Among various DE matrices, polyacrylate rubber (AR) is especially promising owing to their intrinsically high dielectric constant (εr) and good mechanical performance. In particular, its mechanical behavior is close to that of porcine bladder tissue, making it a potentially good material for soft biomedical actuators for artificial bladder constructs. To achieve high actuated strain, which requires highεr, high breakdown strength, and low elastic modulus, an AR DE composite filled with silane-functionalized TiO2was fabricated, exhibiting good electromechanical performance enabled by strengthened interfacial polarization. To improve compatibility between TiO2and AR matrix, TiO2was preferentially modified with a silane coupling agent (CA) that features a double bond as its functional group, which can be introduced on TiO2surface and participate in vulcanization with AR, thereby forming co-crosslinking bridges that strengthen interfacial bonding, improve filler dispersion, and increase interfacial polarizability within the matrix. As a result, at relatively low filler loadings, the composite exhibits a significantly increasedεr, while maintaining low modulus, low dielectric loss and high elasticity. The 10 CA@TiO2/AR composite exhibits a maximal actuated strain of 7.9% at 31.9 kV/mm without pre-stretch, which is 1.48 times that of pure AR and 1.32 times that of the 10 TiO2/AR composite.

Overcoming the sluggish water dissociation kinetics in alkaline media and seawater remains a critical challenge for scalable green hydrogen production, requiring the development of efficient water-splitting electrocatalysts. Here, we conducted an Ru-Co/TiO 2 catalyst, which features an oxygen-vacancy-rich titanium dioxide (TiO 2 ) support anchoring ruthenium (Ru) and cobalt (Co) species, for hydrogen evolution reaction (HER) in alkaline electrolytes. Comprehensive spectroscopic analyses reveal that the microwave-induced oxygen vacancies facilitate the effective anchoring and high dispersion of Ru-Co bimetallic sites while concurrently enhancing electronic interactions. This markedly reduces the kinetic barrier for water dissociation to adsorbed hydrogen intermediates and optimizes the hydrogen adsorption/desorption behavior, thereby synergistically boosting HER activity. Far surpassing its single-metal counterparts, the resulting Ru-Co/TiO 2 maintained stable operation for over 100 h, delivering remarkably low overpotentials at 10 mA cm −2 : 51 mV in 1.0 M KOH, 69 mV in alkaline seawater, and 293 mV in natural seawater. This work demonstrates general and scalable approaches that integrate support defect engineering with trace-level bimetallic modulation, providing valuable insights into the design of low-noble-metal, high-performance electrocatalysts for practical water and seawater electrolysis.

In this work, a dual-potential ratiometric electrochemiluminescence (RECL) sensor for the detection of tetracycline (TC) was constructed based on TiO 2 @g-C 3 N 4 (luminophore) and MWCNTs@Au NPs (promoter). The RECL signals were derived from the anodic peak (TiO 2 @g-C 3 N 4 –TPrA) and the cathodic peak (TiO 2 @g-C 3 N 4 –K 2 S 2 O 8 ). With the addition of TC, the anodic ECL signal remained unchanged and served as an internal reference, while the cathodic ECL signal decreased due to competitive co-reactant consumption. This ratiometric readout mitigates false-negative results commonly encountered in single-output ECL assays by correcting for nonspecific signal fluctuations. Under optimal conditions, a linear relationship was observed between the ratiometric signal (I a /I c ) and the logarithm of TC concentration (lgC TC ) from 1.0 × 10 −12 to 1.0 × 10 −8 mol L −1 . The linear equation was I a /I c = 1.056 + 0.057 lgC TC (R 2 = 0.997). The detection limit was 3.3 × 10 −13 mol L −1 (S/N = 3). The proposed sensor was successfully applied to detect TC in real samples.

The persistent contamination of aquatic systems by tetracycline antibiotics necessitates the development of efficient and sustainable adsorbents. Herein, a one-step deep eutectic solvent (DES) strategy is developed for the synthesis of carbon/oxygen co-doped hexagonal boron nitride (BCNO) nanosheets, using a ternary DES (H 3 BO 3 /urea/guanidine hydrochloride) as an all-in-one precursor and self-templating medium. The resulting BCNO material exhibits an ultrahigh tetracycline adsorption capacity of 428.5 mg g −1 . In situ pyrolysis analysis combined with theoretical simulations reveals that the DES-guided process facilitates synergistic heteroatom doping and the formation of a hierarchically porous structure enriched with Lewis acid-base sites. The adsorption process follows a multilayer chemisorption mechanism, driven by the concerted contribution of π-π stacking, hydrogen bonding, and Lewis acid-base coordination. The material exhibits excellent regenerability, retaining >85% of its original adsorption efficiency after five consecutive cycles. This work not only presents a scalable and eco-friendly route to functional BN nanomaterials but also provides fundamental insights into the molecular-level design of high-performance adsorbents for environmental remediation.

The accumulation of hydrogen in confined environments presents significant safety hazards, highlighting the need for efficient hydrogen getters. Although the PtRu/CNFs-DEB hydrogen getter facilitates the synergistic hydrogenation of both alkynyl and phenyl groups in DEB under mild conditions, its effectiveness is substantially diminished by trace amounts of carbon monoxide (CO), which strongly adsorbs onto Pt active sites. This study introduces a Ru-based oxide barrier layer (RuO 2 ) onto PtRu/CNFs to construct a PtRu-RuO 2 /CNFs composite catalyst. The incorporation of the oxide layer increases the specific surface area from 19.73 to 122.43 m²/g, promotes electron transfer from RuO 2 to Pt, and induces a downshift in the Pt d -band center, consequently reducing the CO adsorption energy. In a H 2 atmosphere containing 500 ppm CO, the PtRu-RuO 2 /CNFs catalyst achieves 85.2% conversion of the alkynyl groups and 21.5% conversion of the phenyl groups in DEB after 10 h. In a 100-hour durability test, it maintains a hydrogen uptake capacity of 600 mL/g — 1.75 times higher than that of PtRu/CNFs — and removes 70% of ambient H 2 . Notably, this newly developed catalyst exhibits broad substrate compatibility, effectively facilitating the transformation of not only DEB but also a diverse array of other aromatic compounds—thereby underscoring its robust catalytic versatility. This study demonstrates that the oxide barrier strategy significantly enhances CO tolerance, hydrogenation efficiency, and long-term stability, providing a promising pathway toward high-performance hydrogen getters for practical applications.

Noble metal nanosensitizers such as Pt and Pd are widely employed to enhance the H 2 sensing performance of semiconductor metal oxide gas sensors owing to their superior capability for H 2 adsorption and dissociation; however, they exhibit poor resistance to CO, a gas that commonly coexists with H 2 , leading to cross-response and false alarms in real-world application scenarios. In this work, we design a wireless gas sensor based on Au nanocluster-functionalized SnO 2 nanosheets. The sensor exhibits exceptional sensitivity (43.2 ppm -1 ), a low detection limit (100 ppb), rapid response time (11 s), excellent selectivity, and strong anti-interference capability against CO. Notably, owing to their ultra-small particle size and high catalytic activity, the Au nanocluster-functionalized SnO 2 nanosheets show a response 51.1 and 1.6 times higher than that of pristine SnO 2 and conventional Au nanoparticle-functionalized SnO 2 nanosheets. Moreover, when CO at a concentration 60 times higher than H 2 is introduced into the H 2 stream, the sensor response changes by only 7.8%. Furthermore, a handheld detector is developed for hydrogen leak detection and early warning. This work presents an alternative strategy for the fabrication of high-performance H 2 sensors with superior CO resistance by employing gold nanoclusters as a sensitizer in place of conventional Pd-based materials.

Abstract Global warming has spurred interest in CO2 utilization. Coupling reverse water–gas shift (RWGS) with hydroformylation allows olefins to react with H2/CO2 to produce valuable aldehydes, which is a profitable reaction and helps with carbon fixation. However, temperature mismatch between the two reactions and limited mechanistic understanding hinder the rational design of catalysts. Using density functional theory (DFT) calculations and experimental evaluations, we investigated the effects of different phosphine ligands and acid additives on the performance of silane-free CO2 hydroformylation. Formic acid alters the CO2 activation pathway and reduces the energy barrier, thereby improving catalytic activity and chemoselectivity. The effects of reaction conditions reveal a competitive relationship between CO2 reduction and olefin carbonylation, suggesting that balancing RWGS and hydroformylation rates enhances catalytic performance. Our work not only deepens the mechanism understanding of silane-free CO2 hydroformylation but also paves the way for the rational design of subsequent high-performance catalysts.

Metal Fe and nonmetal S were co-doped in NiP to modulate the electronic structure of NiP. • Metal Fe doping can improve the electroconductive of the NiP, improving the electron transfer ability and reaction kinetics of HER. • Nonmetal S doping can modulate the band structure for the high electronegativity of S element. • The synthesized Fe, S-NiP exhibited an overpotential of 35 mV at the current density of 10 mA/cm 2 . Nickel phosphide (NiP) is an effective non-noble metal electrocatalyst for the hydrogen evolution reaction (HER). However, the application of NiP is limited for the poor hydrogen adsorption and slow charge transfer during HER process. Herein, metal Fe and nonmetal S were co-doped into NiP to overcome an aforementioned drawbacks of NiP. Metal Fe doping can improve the electroconductive of the NiP, improving the electron transfer ability and reaction kinetics of HER. Nonmetal S doping can modulate the band structure for the high electronegativity of S element. The optimized d-band centers of Ni site benefited the HER reaction and improved the catalytic performance of Fe, S-NiP. The synergistic effect of metal and nonmetal doping further enhanced the catalytic activity by optimizing proton adsorption and hydrogen desorption. This work provided a guidance for metal and nonmetal co-doping for transition metal-based materials’ catalytic performance improvement.
