Cellulose-based materials are currently considered prime candidates for replacing petrochemical plastics because they are biodegradable and cost-effective, while the insufficient hydrophobicity makes them fail to meet application demands, which is a primary issue to be addressed. This work developed a green, catalyst-free approach to prepare high-hydrophobicity amidated cellulose (ADC) by anchoring the COOH-containing oleic acid (OLA) onto NH 2 -containing aminated cellulose (AMC) via amide bonds. The unsaturated fatty acid tail provides a hydrophobic barrier in ADC films . The surface water contact angle of the ADC film reached 133° and remained above 110° for at least one hour. Subsequently, the ADC suspension was applied on the surface of paper from old corrugated container (P-OCC) by an impregnation approach to investigate the improvement of hydrophobic properties. The results showed that the hydrophobicity of P-OCC was increased by ADC, with the water contact angle reached to 132° from 0°. Noticeably, the tensile strength of the ADC impregnated P-OCC (A-POCC) also increased by 2 times. This indicates that with excellent hydrophobicity and mechanical strength , the ADC has great potential application in green functional coating materials.

New type of liquid embolic agents based on a liquid crystalline material of glyceryl monooleate (GMO) was developed and evaluated in this study. Ternary phase diagram of GMO , water and ethanol was constructed and three isotropic liquids (ILs, GMO:ethanol:water = 49:21:30, 60:20:20 and 72:18:10 (w/w/w)) were selected as potential liquid embolic agents, which could spontaneously form viscous gel cast when contacting with water or physiological fluid. The ILs exhibited excellent microcatheter deliverability due to low viscosity, and were proved to successfully block the saline flow when performed in a device to simulate embolization in vitro . The ILs also showed good cytocompatibility on L929 mouse fibroblast cell line. The embolization of ILs to rabbit kidneys was performed successfully under monitoring of digital subtraction angiography (DSA), and embolic degree was affected by the initial formulation composition and used volume. At 5th week after embolization, DSA and computed tomography (CT) confirmed the renal arteries embolized with IL did not recanalize in follow-up period, and an obvious atrophy of the embolized kidney was observed. Therefore, the GMO-based liquid embolic agents showed feasible and effective to embolize, and potential use in clinical interventional embolization therapy.

A TiO 2 /MWCNTs/Al 2 O 3 /NF (TiO 2 nanoparticles/multi-walled carbon nanotubes /Al 2 O 3 -modified nickel foams) composite filter was prepared through grown of MWCNTs upon Al 2 O 3 -modified nickel foams using chemical vapor deposition (CVD) method and then coated TiO 2 nanoparticles onto MWCNTs using dip-coating method. The MWCNTs forms a network-like structure on the surface layer of composite filter. The BET surface area of TiO 2 /MWCNTs/Al 2 O 3 /NF composite filter is more than 375 times higher than that of the pristine nickel foam. The degradation performance of oil particles was evaluated. Under optimized reaction conditions, 90% of the oleic acid on the filter was decomposed after 25 h. In addition, the effect of reaction temperature and light intensity were studied. Increased reaction temperature and light intensity were found to significantly improve the degradation rate and restrain the formation of refractory product. Furthermore, a parallel reaction kinetic model was adopted for degradation of oleic acid on the composite filter. The composite filter can reduces the accumulation of oil particles on the filter and the energy consumption of the filter. This approach proposes a new way to treat the cooking fume emission at residential building roofs.

Metastable hcp-Ni enables the synthesis of highly dispersed and stable Ni/Al 2 O 3 catalyst • Highly dispersed Ni/Al 2 O 3 catalyst delivers 75.7% CO 2 conversion and 100-h stability • Original hcp-Ni particles spontaneously transform into fcc-Ni clusters of ∼2.3 nm • Small Ni clusters promote CO 2 methanation via monodentate formate intermediate • Fcc-Ni precursors undergo severe sintering to ultra-large and less-active particles Ni-based catalysts are promising candidates for CO 2 methanation while their practical applications are limited by particle agglomeration and deactivation. Here, we report a facile strategy to fabricate a highly dispersed and stable Ni/Al 2 O 3 catalyst using metastable hexagonal close-packed (hcp)-Ni as a precursor. Comprehensive characterization reveals that the initial hcp-Ni (∼12.0 nm) spontaneously transforms into uniform face-centered cubic (fcc)-Ni nanoparticles (NPs) of ∼2.3 nm on γ -Al 2 O 3 support during H 2 reduction and CO 2 methanation reaction. The small Ni particles contribute to improved Ni 0 proportion on catalyst surface. In contrast, the original fcc-Ni precursors are prone to sintering, forming ultra-large and less-active Ni aggregates. The highly dispersed Ni NPs derived from hcp-Ni enhance CO 2 adsorption-activation and facilitate the formate-mediated reaction pathway. The resulting hcp-Ni/Al 2 O 3 catalyst delivers a CO 2 conversion of 58.2% with a CH 4 selectivity of 85.4% at 460 °C and endows robust stability exceeding 100 hours. The optimal CH 4 space time yield reaches 179.5 mmol·g cat −1 ·h −1 , exceeding 2.4 times that of fcc-Ni/Al 2 O 3 . This work establishes a reliable synthesis paradigm rooted in crystal-phase regulation, enabling the manufacture of highly dispersed and stable Ni-based catalysts for efficient CO 2 methanation.

Achieving band-selective control of infrared emissivity is crucial for enhancing electric heating efficiency and minimizing energy loss in non-targeted spectral regions, such as lithium battery drying. Here, this work reports a photonic crystal infrared radiation heater (PC-IRH) that integrates an ITO/Ag/glass powder composite heating layer with a three-dimensional TiO 2 photonic crystal coating. Unlike conventional broadband infrared heaters or high-emissivity ceramic coatings, the PC-IRH uses the photonic band-gap effect of ordered TiO 2 microspheres to spectrally reshape the broadband thermal radiation generated by the underlying heating layer, selectively suppressing radiation in non-target bands while concentrating emission in the absorption window of the target material. TiO 2 microspheres synthesized via the sol-gel method, were deposited onto an ITO/Ag composite heating layer via screen printing, repeated roll-pressing, and high-temperature sintering to form a three-dimensional photonic crystal (PC) structure. By controlling the microsphere diameter and designing based on Bragg's law, the PC-IRH achieves an average emissivity of 91.1% and a peak of 99.4% in the 5.0∼9.6 μm range, and reaches thermal steady state within approximately 20 s. In NMP solvent drying tests, the PC-IRH reduces energy consumption by 18.4% and drying time by 28.7%, while significantly enhancing the mechanical properties of the resulting PVDF films. This work establishes a versatile strategy for material-specific, spectrally selective infrared heating with broad potential in energy-efficient thermal management and precision industrial processes.

The adopted NMAI serves multifunctions: it barricades water/oxygen against ambient degradation, passivates defects to suppress non-radiative recombination, and tunes interfacial energy alignment to balance carrier dynamics. • High luminescence and air stability are simultaneously achieved in perovskite quantum dots via one additive, with PLQY reaching 87.9% and ambient stability over twice the reference. • Ambient-air fabricated NIR-PQLEDs exhibit a peak EQE of 16.15% and T 50 over 140 min, showing over 3-fold EQE and 4-fold operational lifetime relative to control devices. Near-infrared perovskite quantum-dot light-emitting diodes (NIR-PQLEDs) are promising for broad application prospects such as biological imaging and optical communication. However, due to the influence of water and oxygen, the stability of perovskite quantum dots (PQDs) in air environments is usually poor, which hinders their industrial applications. In this work, by introducing multifunctional ligand 1-naphthylmethylammonium iodide (NMAI) for surface modification of PQDs, we successfully realized high-efficiency and stable NIR-PQLEDs fabricated under ambient air conditions. Here, NMAI mainly possesses the following functions: 1) Its hydrophobic aromatic naphthalene group enhances the surface hydrophobicity of PQDs and contributes to a more compact moisture-resistant ligand shell, thereby effectively suppressing water and oxygen erosion under ambient air conditions. 2) The synergistic effect of NMA + cations and I − anions achieves efficient defect passivation, thus suppressing non-radiative recombination. 3) The inherent dipole characteristic of NMAI reconstructs the surface of PQDs, optimizing interfacial energy-level alignment and balancing carrier dynamics. Consequently, the photoluminescence quantum yield (PLQY) of PQD film increases from 74.4% to 87.9%, with remarkably enhanced stability in air environment. Benefiting from this strategy, air-processed NIR-PQLEDs achieve a peak external quantum efficiency (EQE) of 16.15%, representing a more than threefold enhancement compared to the pristine device. Meanwhile, the operational half-lifetime (T 50 ) is extended by more than fourfold to over 140 min. This work provides a novel strategy for air-compatible, low-cost, and scalable fabrication of high-performance NIR-PQLEDs, which is of great significance for advancing their optoelectronic applications in the future.

Achieving stable light emission under large, repeated, and multiaxial deformation remains challenging due to the intrinsic brittleness and environmental sensitivity of emissive materials. Here, we report a region-selective fabrication strategy that integrates block copolymer (BCP)-guided emissive-domain formation with selective atomic layer infiltration (ALI). This strategy enables the construction of stretchable rigid-soft luminescent films with mechanically compliant matrices and locally protected emissive domains. Block-copolymer self-assembly defines spatially isolated emissive domains, while ALI selectively forms nanoscopic oxide armors only within emitter-containing regions, reinforcing the domains without stiffening the surrounding soft matrix. Finite-element analysis and strain-dependent optical measurements indicate that applied strain is predominantly accommodated by the soft matrix, leaving the rigid emitter domains effectively unstrained. The resulting stretchable luminescent films maintain nearly unchanged optical performance under up to 100% multiaxial strain. The region-selective construction strategy provides a general design route for mechanically robust luminescent systems.

Diabetic cardiomyopathy (DCM) is a major cardiovascular complication of diabetes with limited effective interventions. Using a streptozotocin-induced insulin-deficient, type 1 diabetes-like DCM mouse model, we show that intermittent fasting (IF) improves cardiac function and attenuates myocardial remodeling. Antibiotic-mediated microbiota depletion largely abolished these benefits, whereas fecal microbiota transplantation from IF-treated donors recapitulated cardioprotection, supporting a causal role of the gut microbiota. Metagenomic profiling identified Akkermansia muciniphila ( A. muciniphila ) as a prominent IF-responsive taxon, and A. muciniphila supplementation alleviated cardiac injury without obvious improvement in glycaemia. Integrated serum and heart metabolomics identified 1-methyl-L-histidine as a microbiota-associated metabolite reduced in diabetes but restored by IF and A. muciniphila . In vitro and ex vivo assays further supported an L-anserine-linked microbial route for 1-methyl-L-histidine generation. Importantly, oral 1-methyl-L-histidine supplementation recapitulated key cardioprotective effects, remodeled cardiac lipid homeostasis, and reduced lipid peroxidation and oxidative injury. Together, these findings support a gut microbiota–metabolite–lipid axis associated with IF-related cardioprotection in DCM and highlight microbial metabolites as tractable targets to complement dietary intervention.

Optoelectronic synapses that integrate light sensing
and processing
functions have attracted significant interest for their potential
to develop neuromorphic vision systems. In particular, an all-optically
modulated device is highly desired for high-efficiency image information
processing. Here, an optoelectronic synapse with all-optical modulation
based on perovskite nanocrystal and InGaZnO (IGZO) heterojunctions
is demonstrated. Excitatory and inhibitory synaptic plasticity can
be obtained under 320 and 532 nm irradiation, which stem from the
ionization and deionization process of oxygen vacancies in IGZO. Moreover,
five basic optoelectronic logic operations are implemented in the
optoelectronic synapse via fully light-controlled methods. By utilizing
the frame difference algorithm, the function of motion detection is
demonstrated for recognizing classic moving vehicles with an accuracy
exceeding 90%. This work provides a promising approach to developing
all-optically modulated artificial synapses and shows great potential
in neuromorphic vision systems.

Under the catalysis of MnO 2 , TBHQ can react with Cys to generate fluorescent CDs. • A fluorescence turn-on sensor for detection of TBHQ is proposed based on in-situ formation of fluorescent CDs. • This sensor is capable of quantitatively measuring the concentration of TBHQ in edible oils. Excessive intake of the food additive tert -butylhydroquinone (TBHQ) causes potential hazards to the human body. Designing an easy-to-fabricate and efficient TBHQ sensor is of great research significance. We found that in the presence of MnO 2 , TBHQ can react with cysteine (Cys) to generate fluorescent carbon dots (CDs). Inspired by this simple fluorogenic reaction, a turn-on sensor for TBHQ detection is proposed based on in-situ formation of fluorescent CDs. The sensor offers a linear range of 1–200 μM and a detection limit as low as 0.06 μM. Due to its simple reaction precursors and unambiguous reaction mechanism, this sensor demonstrates good practicability for TBHQ measurement in edible oils. This fluorescence turn-on in-situ sensor, which does not require pre-synthesized materials, offers considerable potential for on-site detection of TBHQ.

Initial water additions, which serve as a critical variable for regulating the synthesis of diacylglycerol (DAG) from oleic acid esterification reaction, have not been sufficiently investigated regarding the molecular mechanism by which lipase is affected. This study elucidated that the initial water additions effectively modulated the conformational flexibility of the lipase at the interface, promoting the esterification process and enhancing the glycerol dioleate yield. Subsequently, a multi-scale research methodology was employed, gradually revealing the water-mediated catalytic mechanism. The results demonstrated that a 2 wt.% initial water addition significantly increased both esterification conversion rate and esterase activity. Moreover, secondary structure (α-helix increased) and tertiary structure (fluorescence intensity enhanced) indicated that an appropriate amount of water contributed to maintaining the conformational integrity of the enzyme molecules. Additionally, molecular dynamics (MD) simulations revealed that DAG synthesis was influenced by the initial water additions through the promotion of further opening of the lipase lid at the oil-water interface. This article systematically showed how water-regulated interfacial activation of lipase controlled the esterification process, thereby providing a theoretical foundation for the directed synthesis of structured acylglycerols.

A inorganic, biocompatible material system that replaces non-degradable petroleum-based polymers was proposed. • The sensor achieves a rapid response time and equally fast recovery time, excellent cyclability (>4000 cycles). • The sensor exhibits superhydrophobicity, self-cleaning capability, and anti-biofouling properties. • The sensor demonstrates remarkable resistance to mechanical abrasion, UV irradiation, and microbial adhesion. Conventional flexible sensors often suffer from inherent trade-offs among performance, durability, and environmental sustainability. To address these challenges, we propose a novel, inorganic-skeleton-based ternary composite film composed of hydroxyapatite nanowires (HAPNWs), aluminum silicate fibers (ASFs), and carbon nanotubes (CNTs) for high-performance and eco-friendly wearable motion sensing. The film is fabricated via a facile and green wet-process, and its microstructure and conductivity are optimized by tuning the CNT content (defined as the weight ratio of CNTs to the total weight of HAPNWs and ASFs). At an optimal loading of 15 wt%, a uniform and continuous 3D conductive network is formed, enabling the sensor to exhibit a high real-time sensitivity with a rapid response time of 388 ms and an equally fast recovery time of 290 ms, as well as excellent stability over thousands of bending cycles. Furthermore, a synergistic hydrophobic modification using stearic acid and polydimethylsiloxane (PDMS) endows the film with superhydrophobicity (water contact angle >150°), self-cleaning capability, and outstanding anti-biofouling properties. The robust inorganic HAPNW/ASF skeleton ensures remarkable thermal stability (up to 250°C) and chemical inertness, while the hydrophobic coating provides exceptional resistance to mechanical abrasion, UV irradiation, and liquid penetration. This work demonstrates a sustainable material strategy that replaces petroleum-based polymers with a biocompatible inorganic matrix as the structural backbone, offering a promising platform for durable, high-performance wearable sensors and electronic skins in demanding environments.
