Poly(ethylene terephthalate) (PET) accounts for 8 % of global plastic production and 12 % of solid waste, driving extensive research into innovative recycling strategies. Nonetheless, performance degradation of mechanical recycling and high cost of chemical routes, highlighting the urgent need for cost-effective PET recycling solutions. This study presents a “one-pot” upcycling approach based on hydroxy transesterification, which directly converts PET waste into high-performance copolyesters. A key advantage of this method is the elimination of solvents and the avoidance of complete depolymerization using excess ethylene glycol or methanol. Thermal and mechanical analyses reveal that upcycled poly(ethylene- co -1,4 cyclohexanedimethanol terephthalate) (PETG) exhibits properties comparable to commercial PETG. Furthermore, we successfully synthesized a series of heat-resistance copolyesters using various PET waste sources, rigid diols with varying reactivity (2,2,4,4-tetramethyl-1,3-cyclobutanediol, spiroglycol, and isosorbide)—demonstrating the broad applicability of this strategy. Techno-economic analysis (TEA) and life cycle assessment (LCA) demonstrate a 27.2 % reduction in production costs, along with 68 % and 84 % reductions in global warming potential and fossil fuel depletion, respectively. Overall, this platform provides a sustainable and cost-effective pathway for the upcycling of PET waste.

This study develops a polyvinyl alcohol hyperstretchable cellulose-based hydrogel triboelectric nanogenerator (PH-TENG) for non-invasive cardiovascular monitoring. The device fabrication utilizes polyvinyl alcohol and hydroxyethyl cellulose, with performance optimization achieved through synergistic material and architectural design. Experimental characterization reveals the PH-TENG exhibits high sensitivity (0.543 kPa −1 ) and rapid response time (41 ms), enabling precise arterial pulse wave detection with clear characteristic peak resolution. The proposed monitoring strategy integrates pulse wave signals from multiple arterial sites, employing peak interval difference extraction for cardiovascular assessment. Comparative validation demonstrates strong correlation between PH-TENG-derived heart rate data and commercial motion sensor measurements. Implementation of Binary Generalized Linear Model Logistic Regression yields 100 % accuracy in distinguishing subjects’ heart rate pulses pre-exercise and post-exercise. The developed Health Monitoring and Assessment System (HMAS) demonstrates reliable performance for long-term cardiovascular monitoring. This work provides an effective solution for non-invasive, multi-parametric physiological monitoring, establishing a technological foundation for cardiovascular disease diagnosis and prevention. The system shows potential for applications in personalized healthcare and smart sports monitoring.

A facile two-step modification method using dodecyltrimethoxysilane (DTMS) was developed to fabricate a superhydrophobic wood sponge for oil–water separation from natural green renewable balsa wood. First, alkali treatment was performed on balsa wood to remove hemicellulose and lignin to obtain a rough surface and micron-sized pores, preparing flexible balsa wood (FBW). Second, DTMS was grafted onto the surface of FBW via solution impregnation to construct a micro/nano-coating, yielding a dodecyltrimethoxysilane decorated wood sponge (DWS). The DWS surface exhibited a high water contact angle (WCA) of 150.5°, confirming its superhydrophobicity. DWS demonstrated effective oil absorption from oil–water mixtures. Scanning electron microscopy revealed that FBW possessed an interconnected three-dimensional porous network, enabling DWS to achieve high absorption capacities of 12–31 g g −1 for various oils and organic reagents. After 10 cycles, the absorption capacity remained stable, and the WCA was maintained at 143.2°, indicating excellent recyclability. This two-step modification method requires only 5 h of alkali treatment and 2 h of DTMS grafting, and balsa wood is a natural renewable resource. This study provides a potential strategy for developing superhydrophobic materials to address crude oil spills and sewage pollution.

This study aimed to evaluate the effects of microwave treatment on the physicochemical properties of konjac glucomannan (KGM) and the prebiotic potential of KGM fractions with varying molecular weights (Mw). After microwave treatment, KGM exhibited a significant reduction in Mw which resulted in dramatic structural alterations including a transition to rod-like chain conformation and amorphous crystallinity, and fragmented surface morphology. The in vitro fermentation assay revealed that microwave-treated KGM fractions can be more effectively metabolized by gut microbiota, and the lower the molecular weight, the superior the fermentability. Strikingly, both total short-chain fatty acids (SCFA) and valeric acid in lower-Mw KGM fractions showed significantly higher concentrations than those in inulin. Microbiota diversity and composition analysis revealed that consumption of microwave-treated KGM significantly increased the relative abundance of beneficial gut microbiota, especially Firmicutes , Actinobacteria , and Lactobacillus , indicating enhanced prebiotic activity.

Accurate and sensitive detection of protein biomarkers is critical for early disease diagnosis and therapeutic monitoring. This study introduces a novel isothermal proximity CRISPR-Cas12a assay for the detection of C-reactive protein (CRP), a key biomarker for inflammation and disease progression. By employing a DNA-antibody bioconjugate strategy, this method converts protein recognition into DNA signals, enabling multiple signal amplification cascades. The proximity hybridization of antibody probes triggers the Cas12a trans-cleavage activity, releasing detectable signals in fluorescence and commercial test strips. Dual-mode detection was realized, with detection limits of 0.57 ng/mL for fluorescence and 2.63 ng/mL for test strips. Linearity detection ranges were found to be 0.1–100 µg/mL. Furthermore, it exhibited high specificity against interfering substances in blood. Clinical serum samples were analyzed, demonstrating the assay’s robustness and practicality under physiological conditions. This approach enhances the detection of CRP and provides a versatile framework for the quantitative analysis of various protein biomarkers, offering an alternative solution for clinical protein diagnosis for point-of-care tests.

The interaction between birnessite and dissolved organic matter(DOM) is critical for carbon sequestration and heavy metal immobilization. This study investigated humic acid (HA, a representative form of DOM) in mediating the formation of triclinite birnessite (TB) and elucidated the influence mechanisms for carbon sequestration and As(V) immobilization. HA significantly affected both the growth and structural properties of TB. HA induced TB structural transformation from lamellar-like to honeycomb-like, reduced surface negative charge, and increased specific surface area, oxygen vacancies and hydroxyl groups. HA-Mn(III) complexes and pore trapping enhance organic carbon sequestration synergistically. As(V) immobilization was improved by inner-sphere complexation (via hydroxyl coordination) and electrostatic attraction with the maximum adsorption capacities for HA-mediated birnessite (TB-2H) were 65.140 mg·g⁻¹ , 6.4-fold higher than pure TB. Besides, TB-2H shows low manganese release, high stability and good reusability. These findings achieves synergistic carbon sequestration and As(V) immobilization, providing an innovative strategy for environmental remediation.

Phototherapy has emerged as a promising approach for cancer treatment, yet challenges like glutathione (GSH) over-expression and hypoxia within tumors hinder its efficacy. Here, we developed a bismuth-based semiconductor nanotherapy agent, Bi₂S₃ nanorod, stabilized by polyvinylpyrrolidone (PVP). Compared with commercial Bi₂S₃, the Bi₂S₃ nanorods our synthesized exhibited a narrower bandgap, leading to improved electron-hole separation efficiency under near-infrared (NIR) light excitation. Bi₂S₃ nanorods exhibit a high photothermal conversion efficiency of 36.8 %, allowing it to convert light into heat effectively. This thermal effect enhances blood circulation at tumor sites, thereby alleviating hypoxia. Under NIR laser (730 nm) irradiation, Bi₂S₃ nanorods generates elevated levels of cytotoxic reactive oxygen species (ROS) and depletes GSH, increasing oxidative stress and amplifying ROS toxicity, which leads to tumor cell apoptosis. Both in vitro and in vivo experiments demonstrate Bi₂S₃ nanorods' efficacy in synergistic photothermal-photodynamic therapy, suggesting high potential for malignant tumor treatment. This study provides a strategy for enhanced phototherapy and a promising direction for designing integrated nanoplatforms in cancer therapy.

Non-radiative recombination is the key bottleneck to overcome the charge separation problem. Here, we use poly(heptazine imide) (PHI) as a model photocatalyst to investigate the effect of internal electric field (IEF) on non-radiative recombination. Introducing electron-deficient boron atoms into the PHI structure leads to an uneven distribution of in-plane charges, spontaneously polarizing the formation of an IEF. This enhanced IEF can exert a force on the carrier in the opposite direction of the Coulomb force, thus effectively weakening the carrier trapping by the charged defect, thereby suppressing the non-radiative recombination. This is the first systematic research of suppressing non-radiative recombination by IEF in photocatalysis, which provides guiding strategies for addressing the bottleneck of charge separation in photocatalysis.

The analysis and treatment of hazardous substances in food have long been constrained by the dual challenges of limited single-target recognition capability and low resource utilization efficiency. To overcome these limitations, this study developed an ionic liquid-hydrogel material using a polymerization technique. The material featured a stable porous nanostructure and exhibited dual functionality, enabling highly efficient photo-catalytic degradation and adsorptive extraction. Under optimized conditions, it achieved a degradation rate of over 90 % for the dye Amaranth and extraction recovery exceeding 85 % for three benzoylurea pesticides. Mechanistic studies using in-situ IR spectroscopy revealed that the material's efficient and synergistic pretreatment capability for the two distinct classes of pollutants was attributed to the high substrate specificity of its active sites, which ensured that the two pathways operated independently without interference, guaranteeing the reliability of the treatment process. In conclusion, the developed dual-functional material combining with the advantages of low cost, ease of preparation and environmental friendliness provided an innovative strategy for the simultaneous pretreatment of multiple food contaminants and represented a significant advancement in this field.

Titanium dioxide (TiO 2 ) is widely regarded as one of the most promising semiconductor materials for photocatalysis. In this study, through defect engineering, the strong interaction between F − ions and surface Ti 4+ is utilized to induce the generation of oxygen defects, thereby achieving selective etching and exposure of the high-energy {101} crystal plane. At the same time, the coordination effect of Ni on the surface metal active site not only promotes the transition of the forbidden band energy level, but also effectively narrows the band gap of TiO 2 . Through systematic characterization, the successful coordination of Ni and the enhancement of the high-energy state crystal plane stability were confirmed. BET specific surface area test shows that the large specific surface area of Ni-TiO 2 samples provides more surface active sites for photocatalytic reactions. Photoelectric performance tests further show that the introduction of double defect engineering significantly improves the separation and migration efficiency of TiO 2 photogenerated carriers. Degradation experiments showed that Ni-coordinated TiO 2 could efficiently degrade phenol pollutants within 60 min, exhibiting excellent photocatalytic activity. Capture experiments further confirmed that the coupling between non-radical 1 O 2 and free radical •OH is the main active species in photocatalytic degradation. The synergistic effect of the generation of high-energy state facets and Ni coordination significantly improves the separation and migration of photogenerated carriers, thereby enhancing the photocatalytic performance. This work provides a reliable defect engineering strategy for improving the photocatalytic performance of TiO 2 . Graphical In this study, through defect engineering, the strong interaction between F − ions and surface Ti 4+ is used to induce the generation of oxygen defects, thereby achieving selective etching and exposure of high-energy {101} crystal planes. At the same time, the coordination effect of Ni on the surface metal active sites not only promotes the transition of the forbidden band energy level, but also effectively narrows the band gap of TiO 2 . By carefully designing the photocatalytic process, direct degradation of phenol was achieved under the coupling of non-radicals and free radicals. The improvement in photocatalytic activity is due to the increase in specific surface area, which not only broadens the light absorption capacity but also significantly improves the separation and migration of photogenerated carriers. The capture experiment further verified the efficient catalytic mechanism of the Ni-TiO 2 /phenol system, demonstrating that the synergistic effect of the high-energy {101} crystal plane and the highly active Ni coordination was fully utilized to promote the generation of •OH radicals during the reaction and effectively drive the conversion of oxygen molecules into 1 O 2 through vacancy oxidation. This study not only provides a useful reference for the design of high-efficiency and low-energy photocatalysis, but also provides a new solution for the removal of phenol pollution in coal chemical wastewater.

Carbon monoxide (CO) is a gaseous signaling molecule, which can induce mitochondrial dysfunction and tumor cell apoptosis by increasing reactive oxygen species (ROS), making it an attractive therapeutic agent for tumors. However, achieving the optimal therapeutic dose of CO is often difficult due to the limited drug loading capacity of delivery systems. Moreover, the CO therapeutic effect is compromised by the overexpression of glutathione (GSH) in tumor cells. Here, we report a nanodrug constructed by self-assembly of CO-releasing molecule Mn(CO) 5 Br and Cy5-modified cystine transporter antisense oligonucleotides. This nanodrug dissociates and releases CO and antisense oligonucleotide in response to overexpressed H 2 O 2 in tumor microenvironment, resulting in the increase of ROS and the decrease of GSH respectively, thus synergistically inducing tumor cell apoptosis. The self-assembled nanodrug shows satisfactory therapeutic effect of inhibiting tumor growth in tumor cells and animal models, and provide a promising strategy for multifunctional anti-tumor synergistic therapy.

The electrochemical oxidation of biomass-derived 5-hydroxymethylfurfural (HMF) represents a promising pathway to synthesize the critical polymer monomer 2,5-furandicarboxylic acid (FDCA). However, the restricted adsorption of both HMF and OH − to the catalyst surface results in low activity and selectivity. To address this issue, this study introduced an electrochemically assisted strategy to synthesize Ni aerogel with Cu heteroatom doping (Ni 0.94 Cu 0.06 /NF), demonstrating excellent performance for HMF to FDCA conversion in alkaline media. The catalyst achieves 10 mA cm −2 at 1.307 V vs. RHE, with outstanding Hydrogen evolution reaction (HER) activity (10 mA cm −2 @11 mV). Notably, the conversion rate of HMF, the selectivity of FDCA and the Faraday efficiency can reach 99.5 %, 99 % and 97 %, respectively. Scanning Electron Microscope (SEM) and transmission electron microscopy (TEM) demonstrated that the aerogel's self-supported 3D framework with interwoven nanowire structure enables efficient exposure of catalytic sites. X-ray photoelectron spectroscopy (XPS) analysis further showed the modification with Cu forms unique Ni O Cu linkage within the catalyst's surface region, which effectively adjusts the electronic configuration of Ni sites and increases lattice oxygen content, thereby enhancing HMF adsorption. Density functional theory (DFT) revealed that the synergistic interplay between Ni and Cu markedly boosts the uptake capacity for both HMF and OH − , improves the rate-determining step (RDS) thermodynamics by reducing its barrier, and consequently accelerates the HMF oxidation reaction (HMFOR). Our findings elucidate fresh perspectives into the structure-performance relationship of nickel-based catalysts and offer a novel approach for designing advanced electrocatalysts for biomass upgrading.
