Flexible electrochemical sensors based on noninvasive materials can continuously monitor blood glucose levels in sweat, making them ideal for personal diabetes management intelligent devices. It is necessary to construct sweat glucose electrochemical sensors that have the ability to both adjust to human skin and reliably monitor. We first synthesized nickel/cobalt metal–organic framework material (Ni/Co-MOF) nanosheets via a solvent-thermal approach. Then, an oil-based polyurethane (OPU)/polypropylene spun-bonded nonwoven fabric (PPSF) was obtained by coating the surface of PPSF. Silver/silver chloride (Ag/AgCl) paste and conductive carbon (C) paste were printed layer-by-layer on the surface of the OPU/PPSF by screen printing, followed by the immobilization of Ni–Co/MOF nanosheets on the working area using a Nafion solution to form a Ni/Co-MOF@OPU/PPSF flexible glucose sensor for continuous monitoring of glucose in sweat. This Ni/Co-MOF@OPU/PPSF flexible glucose sensor retained the high electrocatalytic activity of Ni/Co-MOF for glucose oxidation and exhibited high sensitivity (159.9 μA/mM·cm2), low limit of detection (LOD) (2 μM), and a wide linearly glucose-monitoring range (10 μM–1 mM). Compared to other nonenzymatic sensors, our Ni/Co-MOF@OPU/PPSF flexible glucose sensor has better immunity than other substances present in sweat. Meanwhile, the Ni/Co-MOF@PPSF flexible glucose sensor not only monitors the glucose in sweat at different body temperatures but also maintains good mechanical flexibility and stable electrochemical properties under bending conditions. It is suggested that our flexible glucose sensor can be used for continuous monitoring of glucose in human sweat. Overall, our glucose sensor can be used for the continuous monitoring of glucose in human sweat.

Background: Efficient degradation of cellulose is a key bottleneck in the industrialization of biofuels. While fungi achieve substrate conversion through precise regulation of cellulase systems, the systematic mechanisms underlying efficient degradation (encompassing gene transcription, extracellular protein cooperation, and product metabolism) remain unclear in specific fungi, especially thermophilic fungi critical for industrial production. Results: (1) C. thermophilum did not induce cellulases under cellobiose, while microcrystalline cellulose (MCC) strongly activated degradation. CtClr-2 acts as a core transcription factor, directly driving the co-expression of key genes including LPMOs, CDH, and CBH; its deletion reduces MCC degradation efficiency by 30%. (2) Enzyme secretion may follow a three-stage cascade pattern (CBH1-A → LPMOs/CDH-1 → CBH1/2-B), where the selective secretion and temporal synergy of oxidases and hydrolase increase the reducing sugar yield by 60.6%. (3) The sugar acid metabolic network may enable efficient utilization of degradation products and potentially help maintain extracellular pH. Conclusions: This study reveals the efficient "transcriptional regulation-enzyme secretion adaptation" synergistic mechanism in C. thermophilum. CtClr-2 coordinates key genes, and staged enzyme secretion optimizes synergy, while sugar acid metabolism ensures homeostasis. These insights advance thermophilic cellulolysis understanding and provide targets for engineering industrial strains through synthetic biology (for example, enhancing enzyme yield and optimizing degradation efficiency), aiding cost reduction in biofuel production.

The high-voltage spinel LiNi 0.5 Mn 1.5 O 4 (LNMO) is a promising cobalt-free cathode with high specific energy, attributed to its high operating voltage (approximately 4.7 V). However, its practical durability is limited by irreversible transition-metal migration, spinel-to-rock-salt phase reconstruction, high-voltage interfacial side reactions, and transition-metal dissolution. Herein, we report a multi-element-doped, cation-disordered spinel LiNi 0.4 Mn 1.4 Fe 0.05 Cr 0.05 Cu 0.05 Nb 0.05 O 4 (HELNMO) synthesized via a solid-state method. Rietveld refinement confirms a single-phase Fd 3̅ m structure with a slightly expanded lattice parameter (8.1857 Å for HELNMO versus 8.1776 Å for LNMO), and energy-dispersive X-ray spectroscopy mapping reveals a homogeneous distribution of the dopant elements. Structural and spectroscopic characterizations consistently confirm enhanced cation disorder in HELNMO, which contributes to favorable electrochemical performance by delivering approximately 130 mAh g −1 at 0.1 C and exhibiting markedly improved cycling stability, retaining 92% of its initial capacity after 1000 cycles at 2 C between 3.5 and 4.9 V. In-situ X-ray diffraction reveals smoother, more continuous lattice evolution of HELNMO than LNMO during (de)lithiation, consistent with a more homogeneous reaction pathway. Post-cycling analyses corroborate suppressed surface rock-salt reconstruction, reduced impedance growth, and alleviated Mn/Ni dissolution. Collectively, multi-element doping coupled with disorder engineering can effectively mitigate transition-metal migration and high-voltage interfacial degradation, providing a practical strategy for durable, high-energy spinel cathodes.

Developing simple and efficient synthesis methods for electrocatalysts is the key to advancing the process of electrochemical CO2 reduction reaction (CO2RR). In this study, we employ the simple hydrothermal method and modulate the pH to prepare the CuO-In(OH)3 heterostructure catalyst. It is found that the prepared lamellar CuO-In(OH)3-12 hetero-composite catalyst accelerates the reaction kinetics, provides more active sites, and strengthens the electronic interaction between Cu and In. The obtained catalyst achieves a notable Faradaic efficiency of 40.26% for C2 products at a current density of 18.5 mA cm-2. This work provides a new approach for the development of hetero-catalysts under synthetic regulation methods and different metal combination selections.

The fine-tuning of reactions in water microdroplets remains elusive. This study demonstrated that trace amounts of positively charged inorganic salts and organic compounds promoted the C O bond reduction of oxaloacetate while inhibiting the C C bond reduction of fumarate within water microdroplets. Similar effects were observed for carbonylated molecules with varying carbon chain lengths. Unlike conventional aqueous solutions requiring millimolar dopant concentrations, dopant levels as low as 10 nM in microdroplets were sufficient to induce these selective promotion and inhibition effects. A potential mechanism involving electrostatic interactions suggested that trace positively charged dopants drove the migration of carboxylated molecules from the microdroplet surface toward its interior. This relocation correlated with the changes in reaction reactivity. These findings could offer a novel approach to mediating reaction selectivity in microdroplets and have broad implications for atmospheric chemistry, chemical synthesis, and prebiotic processes where microdroplets interact with diverse surrounding substances.

Targeted delivery of therapeutics demonstrates great potential for the treatment of atherosclerosis (AS). However, the uncontrolled cargo release from nanocarriers limits their ability to achieve optimal therapeutic functions and outcomes. Herein, we propose a thermo-responsive phase transformation-based strategy for controlled drug release, enabling precise delivery specifically to atherosclerotic plaque sites. We developed a nanomedicine (PDA@A/G) by encapsulating tetradecanol (TD) with atorvastatin (ATV) and hydrogen sulfide (H 2 S) donor GYY4137 into polydopamine (PDA) nanocapsules featuring a small hole. The phase transition of TD from solid to liquid state within the atherosclerotic microenvironment, which has a temperature of approximately 39 °C, triggers the release of H 2 S and ATV. The release of the therapeutic drug and gasotransmitter exerts synergistic effects in regulating oxidative stress, alleviating inflammation, and improving endothelial function, showing dramatic capacity in inhibiting plaque progression. This strategy provides a novel and highly promising paradigm for the development of nanomedicine aimed at the targeted co-delivery of drug and gasotransmitter in AS therapy.

The renewable utilization of phosphorus (P) in sewage sludge is greatly hindered by its low bioavailability . In this study, the co-hydrothermal treatment (co-HTT) of sewage sludge and biomass was conducted to enhance P bioavailability. The dehydration and decarboxylation of sludge organic matter were promoted by co-HTT as evidenced by FTIR and elemental analysis. XPS and XRD results showed that co-HTT facilitated the formation of Al/Fe phosphates in sludge. The results of Hedley's sequential extraction demonstrated that HTT at low temperatures (≤ 155 °C) enlarged the relative abundance of bioavailable P in the sludge from 72 % to as high as 80 % because of the decomposition of organic P. In contrast, at a high temperature of 185 °C, more bioavailable P was converted into insoluble and residual forms. The addition of rice straw in sludge during HTT resulted in a two-fold increase in exchangeable P content, suggesting that rice straw can effectively improve sludge P bioavailability. Cellulose exhibited less influence on sludge P bioavailability than lignin. After lignin addition, the relative abundance of bioavailable P in the sludge was further increased to 91 %, which could be attributed to the greater enhancement effect of lignin on the decomposition of sludge organic matter. These findings reveal that the co-HTT of sludge and lignin-containing biomass may be an effective strategy for improving sludge P bioavailability.

The electrochemical hydrogen evolution reaction (HER) requires highly efficient electrocatalysts with durable and stable performance. In this work, multiwalled carbon nanotubes (MWCNTs) are employed as electrocatalyst carriers, polystyrene microspheres as templates, chitosan as a nitrogen-doped carbon (N–Carbon) source, and cobalt nitrate as a cobalt source to manufacture hollow Co nanoparticle and N–carbon modified CNT (Co/NCNT) composite foam as highly efficient electrocatalysts with durable and stable performance. This composite foam not only has a fast electron transfer rate but also contains more exposed intact sites and ion transport channels, making ion storage and movement easier. In addition, hollow Co nanoparticles (NPs) enhanced the catalyst activity and N–Carbon and MWCNTs enhanced the electrical conductivity of the carbon matrix. The coupling between the hollow Co NPs, N–Carbon, and MWCNTs enhances the electrocatalytic performance of the electrocatalyst in the HER. Compared with other electrocatalysts, the Co/NCNT exhibits lower overpotential (20 mV) at a current density of 10 mA cm−2, lower Tafel slope (27.53 mV dec−1) and stronger cycling durability (2000 cycles) in 1 M KOH. The composite foam developed here may be a potential high-performance HER catalyst.

Lipid hydrotreatment to generate green diesel can weaken the dependence on unrenewable fossil fuels. The catalytic performance of Co catalyst is greatly limited by the dispersion and the number of Co active sites. To solve this problem, the Co-Al nanosheet was synthesized by using Co-Al LDH as the precursor. In the fatty acid hydrotreatment at 220 °C, the Co-Al nanosheet attained 98.0 % conversion and 64.3 % alkane yield, much higher than that of the Co/Al 2 O 3 catalyst (83.7 % conversion and 18.7 % alkane yield). From the catalyst characterizations, the excellent activity of Co-Al nanosheet was mainly ascribed to its high Co content and lamellar structure, exposing massive Co sites with high dispersion and small particle size. In addition, the high percentage of weak acidity, strong interaction between support and Co sites, and the improvement of the decarboxylation route also contributed to its catalytic performance. Moreover, the kinetics of octadecanol hydrotreatment over Co-Al nanosheet and Co/Al 2 O 3 revealed that octadecanol hydrotreatment more easily occurred over Co-Al nanosheet regarding the lower activation energy.

Optical temperature sensing technology, especially the fluorescence intensity ratio (FIR) type sensor based on Er3+, Yb3+ co-doped up-conversion (UC) luminescent materials, presents numerous opportunities in the field of temperature detection. Various Er3+, Yb3+ co-doped fluorides and oxides have been explored for the application of temperature sensing. Most of these Er3+, Yb3+ co-doped sensing materials are phosphors, for which the high temperature phase and chemical stability is still challenging. The Er3+, Yb3+ co-doped oxide single crystal is a promising solution to explore temperature sensing materials with practical application ability. In this work, an Er3+, Yb3+ co-doped LaBMoO6 single crystal (LBMO-SC: Er3+, Yb3+) is grown through flux assisted spontaneous crystal growth technology. Compared with the Er3+, Yb3+ co-doped LaBMoO6 polycrystalline samples (LBMO-PC: Er3+, Yb3+), the LBMO-SC: Er3+, Yb3+ shows improved UC performance with enhanced light emission and prolonged luminescence lifetime. The UC performance improvement results from the more efficient energy transfer between Yb3+ and Er3+. The energy transfer efficiency from Yb3+ to Er3+ in the LBMO-PC: Er3+, Yb3+ powders sintered at 1000 °C for 15 h is 7.3%, while it is 29.7% in the LBMO-SC: Er3+, Yb3+. The strong UC luminescence of LBMO-SC: Er3+, Yb3+ extends the temperature detection range; the luminescence of 4S3/2 → 4I15/2 in LBMO-SC: Er3+, Yb3+ is still measurable even when the temperature reaches 570 K. The LBMO-SC: Er3+, Yb3+ has a maximum value of relative temperature sensitivity of 1.16% K−1 at 300 K. Finally, an optical fiber type temperature sensor with practical application capability is successfully fabricated by using LBMO-SC: Er3+, Yb3+ as the luminescence sensing medium.

The abuse of antibiotics has drawn wide attention owing to their potential risk in human health and ecosystem. As one of the most commonly used sulfonamide antibiotics, sulfamethoxazole (SMX) can hardly be removed by conventional wastewater treatment methods, and thus it has become one of the most frequently detected antibiotics in water environment. In this study, a new cobalt-based heterogeneous catalyst (Co-bHAP) was successfully prepared using the simple impregnation method with animal bone-derived hydroxyapatite (bHAP) as the support, and applied to activate peroxymonosulfate (PMS) for the degradation of SMX in water. The physicochemical properties of Co-bHAP catalyst were investigated by series of characterization methods, and the results showed that this catalyst has a rough and porous morphological structure, as well as homogeneously distributed active component, which is mainly in the form of Co 3 O 4 . The developed Co-bHAP can provide abundant reaction active sites and exhibit excellent catalytic activity and stability in PMS activation . The kinetic constant of Co-bHAP activating PMS to degrade SMX is up to 0.1524 min −1 , which is 4.5 times larger than that of bare Co 3 O 4 . The SMX (20 mg/L) degradation efficiency within 30 min in Co-bHAP/PMS system reached as high as 98.7% and still maintained at 86% after 5 times consecutive operation, with slight cobalt ions leaching less than 0.1 mg/L. Based on radical quenching experiment, electron paramagnetic resonance (EPR) test and XPS analysis, the reaction mechanism was proposed. The balance among Co 3+ / Co 2+ , O 2− /O 2 and PMS decomposition in Co-bHAP/PMS system ensured the continuous generation of sulfate radical (SO 4 •– ) and hydroxyl radical (HO • ), both of which are responsible for SMX degradation, while SO 4 •– plays a leading role. In addition, four possible pathways of SMX degradation were proposed according to the eight detected intermediate products. All the results suggested that this catalyst could have a promising potential in activating PMS to degrade sulfonamide antibiotic pollutants in water.

Inorganic-organic hybridization is a widely used method to develop new functional materials involving polyoxometalates (POMs), affording them with unique synergistic physical and chemical properties. As one of the core topics in hybrid materials, the study of their assembly structures is critical for the optimization of their performances. In the present work, dynamic co-assembly behaviors of several giant surfactants XPOSS-PS (X, POSS and PS denote different polar groups, polyhedral oligomeric silsesquioxane and polystyrene, respectively) and Keggin-type silicotungstic acid H 4 SiW 12 O 40 ( H 4 SiW for short) were investigated. We designed and synthesized three series of giant surfactants that possess heads bearing cationic ( NPOSS-PS , N for ammonium group), neutral ( DPOSS-PS , D for dihydroxyl group) and anionic charges ( APOSS-PS , A for carboxylic acid group), respectively. The different charge types of POSS heads lead to different electrostatic interactions with the anionic POM clusters, resulting in different co-assembly structures in dual mixed solvents. Moreover, we found the POM's loading content and PS chain length are another two important factors that can determine the morphology of co-assembly structures. This work expands the scope of co-assembled structures of POM-based hybrid materials, and provides a platform for the study of the basic physical principles of their co-assembly behaviors.
