Developing low-cost and green biomass derived carbon with high adsorption capacity is an important way to solve heavy metal and organic pollution in water. Herein, triethanolamine, potassium hydroxide, and rice straw were used as raw materials to prepare the heteroatom doping biomass carbon (RSDPC) via solvothermal avenue. The adsorption performance and mechanism of Pb 2 + , Cu 2+ , and methyl orange (MO) on RSDPC were systematically investigated via a series of experimental characterizations, adsorption kinetics, isothermal models, and density functional theory (DFT) calculations. The synthesized RSDPC exhibited the maximum adsorption capacities to Pb 2+ , Cu 2+ , and MO are of ca. 230.2, 170.0, and 346.8 mg·g −1 , respectively, originating from the developed pore structure, considerable specific surface area, and numerous N/O co-doping active sites. Basing on the evaluation of kinetic and isotherm models, the adsorption mechanism of RSDPC to the pollutants is mainly induced by semi-chemical and monolayer adsorption. The cyclic adsorption measurements presented the RSDPC possessed stable adsorption capacity after 5 cycles with the average adsorption rates of ca. 94.33 %, 98.49 %, and 99.95 % to Pb 2+ , Cu 2+ and MO, respectively. The pollutant elimination of RSDPC in different real samples were all near 100 %. Moreover, the adsorption process of Pb 2+ and Cu 2+ ions was controlled by electrostatic interaction and that of MO was controlled by π-π stacking interaction, which was verified by density function theory (DFT) calculations and XPS analysis after adsorption simultaneously. This work developed a green and versatile biomass derived carbon by structural design and N/O heteroatoms co-doping to investigate the microscopic mechanisms of pollutant adsorption via the combination of experiments and theoretical calculations, providing a new method for the resource utilization of agricultural waste in the field of complex sewage purification.

Perovskite oxides are promising anodic electrocatalysts for alkaline saline water electrolysis, yet their performance is often limited by sluggish oxygen evolution reaction kinetics and competing chloride corrosion. Building on Pr0.1Sr0.9Co0.5Fe0.5O3 (PSCF), a candidate previously identified via our transfer learning paradigm, we further leveraged data-driven compositional searching of the A-site configuration, which led to an optimized catalyst with a proper Ce/Sr/Pr ratio (Ce-PSCF). The asymmetric Ce–O–Co motifs invoked a negative charge-transfer regime and activated the evolution of nonbonding oxygen (ONB) states, which reconciled the activity-stability trade-off and promoted a dual-site intramolecular lattice oxygen mechanism, as evidenced by promoted 18O–18O evolution. The electrolyzer with Ce-PSCF lowered the overpotential of the PSCF-based one by 100 mV at 300 mA cm–2 and exhibited 15-fold greater durability. Electrochemical analysis revealed a higher reaction order, promoted *OH coverage, and faster surface reconstruction on the Ce-incorporated electrocatalyst, indicating *OH-controlled chemical-step kinetics. Theoretical insight inferred a variation of the rate-determining step from O–O coupling to secondary OH– refilling with a reduced energy barrier from 0.68 to 0.54 eV. Moreover, ab initio molecular dynamics simulations visualized a dynamically strengthened affinity for OH– and significant repulsion of Cl–, arising from its intrinsic Lewis acidic and basic microenvironment.

Lactic acid bacteria (LAB) fermentation enhances the flavor and nutritional profile of foods. Nevertheless, the specific mechanism by which Lactiplantibacillus plantarum ( L. plantarum ) B22, a strain exhibiting high lipase activity, enhances flavor formation in fermented cream remains unclear. This study employed GC-olfactometry-mass spectrometry (GC-O-MS) volatilomics and lipidomics to elucidate the flavor formation mechanism with L . plantarum B22 in fermented cream. Sensory evaluation demonstrated that L. plantarum B22 fermented cream (LSB) scored significantly higher than commercial starter cultures fermented cream (LS) in terms of texture, taste, aroma, and overall acceptability. The key VOCs were acetoin, 2-nonanone, δ-dodecalactone, δ-octalactone, δ-decanolactone, benzoic acid, 2-hydroxy-3-pentanone, and 2,3-butanedione. Moreover, LSB exhibited elevated levels of polyunsaturated fatty acids (PUFAs), including linolenic acid (LA, 18:2), and eicosapentaenoic acid (EPA, 20:5). Correlation analysis demonstrated that 59 lipid species were significantly associated with the flavor profiles of LSB. Crucially, the FA (18:3) was identified as a key precursor for the biosynthesis of δ-dodecalactone, δ-octalactone, and δ-decanolactone. This study provides novel mechanistic insights into how high-lipase-activity L . plantarum B22 promotes characteristic flavor formation in fermented cream via targeted regulation lipid degradation, offering valuable guidance for developing premium fermented dairy products.

Phosphorus containing flame-retardants with low oxidation states are widely used in Flexible polyurethane foam (FPUF) due to their excellent gas-phase flame retardancy. However, achieving good migration resistance in prepared flame retardant while balancing or even improving the mechanical properties (such as ductility, good rebound ability) and flame retardancy of FPUF remains a challenging issue. To solve the above problem, we have designed diphenylphosphine oxide silicon glycol (DPPSG) that combines a phosphorus-based flame retardant group with a Si-O-C bond structure. Chemically linking DPPSG into the molecular chain of flexible polyurethane foam and mechanical properties at the same time. On one hand, DPPSG has good compatibility with polyether polyols 330, reacting uniformly with isocyanates and participating in the foaming and gelation process of FPUF. This ensures its enduring flame retardancy. On the other hand, the tensile strength and elongation at break of the flame retardant foam (10DPPSG foam) prepared by adding 10% DPPSG of polyether polyol 330 increased by 71.4% and 77.6% respectively. Moreover, even after 100 cycles of compression rebound testing, 10DPPSG foam exhibited excellent elasticity with a permanent compression deformation rate of only 4.9%. This work provides a new approach to develop FPUF that achieves a balance between mechanical and flame-retardant properties.

Qu -aroma is a critical quality indicator for medium–high temperature Daqu (MT- Daqu ). Due to the differences in regional and environmental conditions, these differences are likely to cause variations in the Qu -aroma of MT- Daqu . Despite this, comprehensive research on the variations in Qu -aroma across different regions has been lacking. This study aims to address this gap to analyze the differences in Qu -aroma characteristics of MT- Daqu from seven distinct production areas. Sensory analysis identified seven broad aroma categories and 25 specific aromas characterizing the Qu -aroma of MT- Daqu samples. Chen aroma and roasted aroma were notably more prevalent in MT- Daqu samples from Sichuan compared to those from other regions ( P < 0.05 ). In total, 123 volatile compounds were detected in MT- Daqu , with 42 classified as aroma-active compounds. Among these, 21 aroma-active compounds were identified as markers distinguishing Sichuan MT- Daqu from those produced in non-Sichuan regions, showing significant differences in their concentrations ( P < 0.05 ). Additionally, six major aroma-active compounds were found to significantly contribute to the aroma differences between Sichuan and non-Sichuan MT- Daqu . This study delineates the distinct Qu -aroma characteristics of MT- Daqu from various SAB production areas. The insights gained from this research offer valuable guidance for optimizing flavor profiles in MT- Daqu production. Graphical

Background: Blueberry anthocyanin such as Cyanidin-3-O-glucoside may help prevent Alzheimer’s disease. We aimed to investigate the preventive and therapeutic effects of Cyanidin-3-O-glucoside against Aβ1–42-induced apoptosis of SH-SY5Y cells as well as the underlying mechanisms. Methods: Cell viability and intracellular and mitochondrial reactive oxygen species were detected by MTT, a reactive oxygen species detection kit, and a MitoSOX red mitochondrial superoxide indicator. The mitochondrial membrane potential, intracellular calcium ion content, and adenotriphophate (ATP) were identified via a mitochondrial membrane potential detection kit, calcium ion detection kit, and ATP detection kit, and apoptosis was detected via flow cytometry. Transcription of apoptosis-related genes was detected using real-time fluorescence quantitative polymerase chain reaction, and expression of apoptosis-related proteins was identified using Western blot. Results: We found that Cyanidin-3-O-glucoside could downregulate the expression of cytochrome c, caspase 9, caspase 3, and other genes and proteins, which consequently reduced the rate of apoptosis. Additionally, it could upregulate Bcl-2 gene and protein expression, downregulate Bax gene and protein expression, regulate mitochondrial membrane permeability and calcium-release channels, reduce calcium influx into mitochondria, maintain intracellular calcium ion levels, reduce intracellular levels of reactive oxygen species and increase ATP levels, maintain the mitochondrial membrane potential at a normal level, maintain normal mitochondrial functioning, and prevent apoptosis. Discussion: Taken together, Cyanidin-3-O-glucoside showed dose-dependent preventive and therapeutic effects against Aβ1–42-induced apoptosis of SH-SY5Y cells. Conclusions: Cyanidin 3-O-glucoside showed a better preventive effect than therapeutic effect against Aβ1–42-induced apoptosis in SH-SY5Y cells.

A photoresponsive S-(o-nitrobenzyl)-l-cysteine N-carboxyanhydride (NBC-NCA) monomer was for the first time designed, and the related poly(S-(o-nitrobenzyl)-l-cysteine)-b-poly(ethylene glycol) (PNBC-b-PEO) block copolymers were synthesized from the ring-opening polymerization (ROP) of NBC-NCA in DMF solution at 25 °C. Their molecular structures, physical properties, photoresponsive self-assembly, and drug release of PNBC-b-PEO were thoroughly investigated. The β-sheet conformational PNBC block within copolymers presented a thermotropic liquid crystal phase behavior, and the crystallinity of PEO block was progressively suppressed over the PNBC composition. The characteristic absorption peaks of these copolymers at about 310 and 350 nm increased over UV irradiation time and then leveled off, indicating that the o-nitrobenzyl groups were gradually photocleaved from copolymers until the completion of photocleavage. The PNBC-b-PEO copolymers self-assembled into spherical nanoparticles in aqueous solution, presenting a photoresponsive self-assembly behavior, together with a size reduction of nanoparticles after irradiation. The anticancer drug doxorubicin can be released in a controlled manner by changing the light irradiation time, which was induced by gradually photocleaving the PNBC core of nanoparticles. This work provides a facile strategy not only for the synthesis of photoresponsive polypeptide-based block copolymers but also for the fabrication of photoresponsive nanomedicine potential for anticancer therapy.

Typically, SO2 unavoidably deactivates catalysts in most heterogeneous catalytic oxidations. However, for Pt-based catalysts, SO2 exhibits an extraordinary boosting effect in propane catalytic oxidation, but the promotive mechanism remains contentious. In this study, an in situ-formed tactful (Pt–S–O)-Ti structure was concluded to be a key factor for Pt/TiO2 catalysts with a substantial SO2 tolerance ability. The experiments and theoretical calculations confirm that the high degree of hybridization and orbital coupling between Pt 5d and S 3p orbitals enable more charge transfer from Pt to S species, thus forming the (Pt–S–O)-Ti structure with the oxygen atom dissociated from the chemisorbed O2 adsorbed on oxygen vacancies. The active oxygen atom in the (Pt–S–O)-Ti active structure is a robust site for C3H8 adsorption, leading to a better C3H8 combustion performance. This work can provide insights into the rational design of chemical bonds for high SO2 tolerance catalysts, thereby improving economic and environmental benefits.

Composite polymer electrolytes (CPEs) have shown extraordinary promise for use in all-solid-state lithium metal batteries (LMBs) because of their tunable merits in ionic conductivity and mechanical flexibility. Their practical application is however hindered by the poor interface stability and the uncontrollable Li dendrite formation. Addressing these two issues, we report an in-situ formed Li-Al-O interface layer between CPEs and Li metal anode by introducing Al 2 O 3 nanoparticles in CPEs. X-ray photoelectron spectroscopy results indicated that the CPE-Al 2 O 3 could slowly release Al atoms which react with Li metal to form the current Li-Al-O interface layer. We highlight that the Li-Al-O interface layer can stabilize lithium deposition/stripping over 1400 h in lithium symmetric batteries, and afford an impressive cycle life of 300 cycles in LiFePO 4 -Li batteries with almost no capacity loss. The present findings demonstrate that in-situ constructing a slow-release Li-Al-O interface layer is an easy and effective approach to stabilize the solid electrolyte interface and suppress the Li dendrites growth. Furthermore, the obtained batteries show excellent cycling stability, indicating the strategy with in-situ formed CPEs shed light on improving the processability of fabrication of high-performance electrolytes.

Graphical A new zinc-ion hybrid capacitor assembled by using a Zn@annealed ZIF-8 anode and ZIF-8 derived C cathode provides a capacity of 135.5 mAh g −1 and an energy density of 108.4 Wh kg −1 with a power density of 800 W kg −1 at 1.0 A g −1 . Zn is a promising anode for aqueous energy storage owing to it intrinsic superior properties such as large capacity, abundant reserves, low potential and safety. But, the growth of dendrites during charge and discharge leads to a decrease in reversibility. In addition, further development of zinc-ion hybrid capacitors (ZICs) is seriously challenging because of the lack of an exceptional cathode. Herein, we use ZIF-8 annealed at 500 °C (annealed ZIF-8) as a host material for stable and dendrite-free Zn anodes. Utilization of annealed ZIF-8 results in dendrite-free Zn deposition and stripping as a result of its porous construction, which contains trace Zn. Furthermore, we firstly proposed innovative N,O dual-doped carbon which was designed by the derived ZIF-8 (ZIF-8 derived C) as cathode for high-energy and power-density ZICs. The new ZIC assembled by Zn@annealed ZIF-8 anode and ZIF-8 derived C cathode provides a capacity of 135.5 mAh g −1 and an energy density of 108.4 Wh kg −1 with a power density of 800 W kg −1 at 1.0 A g −1 . In addition, it shows outstanding cycling stability of 91% capacity retention after 6000 cycles at 5.0 A g −1 . Moreover, the solid-state ZICs can drive LEDs and smart watches. This ZIC holds promise for the practical application of supercapacitors.

Designing hydrogen evolution reaction catalysts with high performance in alkaline conditions is important for reducing energy consumption during water electrolysis. This study reports an electrodeposition–calcination–electrodeposition strategy to construct the Ni–Mo–O/Ni4Mo nanointerface on an N-doped carbon support derived from polyaniline on carbon fiber paper. The N-doped carbon support not only stabilizes the metal/metal oxide nanointerface but also generates more active intrinsic sites and electrical conductivity via the metal–N interaction. The obtained Ni–Mo–O/Ni4Mo@NC displays a low overpotential of only 61 mV at a current density of 10 mA cm–2 for alkaline HER in 1 M KOH.

Interfacial solar-driven water evaporation is an appealing technology to mitigate freshwater crisis mainly caused by increasingly aggravated water pollution. Unfortunately, when polluted water is used, toxic organic pollutants might remain or even get enriched, leading to more serious water pollution. Herein, a self-floating bifunctional Fe 2 O 3 /N,O-doped carbon foam (FCF) evaporator is easily prepared by carbonization of waste polyester for simultaneous interfacial solar-driven water production and photocatalytic degradation of organic pollutants. The as-prepared FCF possesses low heat conductivity (0.074 W m −1 K −1 ), 3D interconnected pores, abundant functional groups as well as super-hydrophilicity, which impart FCF with fast water transport, high light absorptivity (98%), good photothermal conversion, and low vaporization enthalpy . Therefore, FCF presents high evaporation performance, e.g., 2.50 kg m −2 h −1 under 1 Sun irradiation, outperforming many advanced solar evaporators. Furthermore, the synergistic effect of heteroatom-doped carbon foam, Fe 2 O 3 nanoparticle , and interfacial thermal energy is certified on the activation of peroxymonosulfate (PMS) to form diverse reactive oxide species (e.g., SO 4 •− ), which promote the degradation of diverse organic dyes or mixed dyes. Compared with FCF and PMS systems, the rate constant of FCF + PMS system (3.79 ×10 −2 min −1 ) is enhanced by 173.8 and 1.6 times, respectively. In outdoor experiments, the amount of freshwater production from per meter square (13 kg) satisfies with 5 adults’ daily water demand, and the dye degradation efficiency reaches 99.8%. The integration of advanced oxidation process into interfacial solar evaporation offers a promising strategy to simultaneously solve freshwater scarcity and sewage disposal.
