Sodium-ion batteries (SIBs), as next-generation energy storage devices, can be made by a similar production process to lithium-ion batteries (LIBs). The key to accelerating their commercialization is to discover appropriate high-performance electrode materials with low cost, nontoxicity, and simple synthetic features. Herein, layered-structure Na 2 Ti 3 O 7 , with the advantages of appropriate charge/discharge plateaus, superior stability, environmental friendliness, and ease of preparation using cheap raw materials, is selected for assembly in full-cell battery packs to evaluate its suitability for practical application. When evaluated in a coin cell, it has a capacity of 77.2 mAh g −1 at 1 A g −1 after 10 000 cycles with capacity retention of 99.9%, demonstrating its excellent stability. In the case of a soft-pack battery, it retains 22.3 mAh g −1 at 0.1 A g −1 and 18.1 mAh g −1 at 0.05 A g −1 after 50 cycles. After cycling, there is no sodium dendrite formation or active material shedding, further confirming its safety in practical application. Therefore, Na 2 Ti 3 O 7 as another intercalation/deintercalation mechanism material has application potential in the future.

The bottleneck of alkaline hydrogen evolution reaction lies in the kinetically sluggish brought from multistep reaction processes involving water adsorption and dissociation, as well as hydrogen adsorption. In this work, we successfully synthesized o-CoSe 2 /c-CoSe 2 heterostructures anchored on MoSe 2 nanosheets to powerfully promote reaction processes. As an electrocatalyst , it exhibits a low overpotential of 112 mV at 10 mA/cm 2 and a Tafel slope of 96.9 mV/dec for an alkaline hydrogen evolution reaction . Moreover, the as-prepared catalyst can behave as both cathode and anode for overall water splitting , which only requires 1.61 V cell voltage at 10 mA/cm 2 . Significantly, the cell voltage can be further reduced to 1.53 V at 10 mA/cm 2 for water electrolysis under the simulated solar irradiation owing to such a semiconductor-based heterostructure that facilitates the separation of photogenerated charges. Here, the improving overall performance of this ternary electrocatalyst is attributed to the multifunctionality and synergistic interaction of different components in this heterogeneous material . The work provides a novel strategy to design active catalysts simultaneously using electric energy and solar energy for effective water splitting.

Tunable fluorescent nanomaterials are of great significance. In this paper, the poly(o-phenylenediamine) (PoPD) nanospheres were synthesized via chemical oxidation polymerization of o-phenylenediamine (oPD) monomers by (NH 4 ) 2 S 2 O 8 (APS) at room temperature. It is interesting that when this fluorescent nanosphere was doped by F, S and Se via a simple hydrothermal progress, the fluorescence spectrum remarkably changed. The emission peak of F-doped and S-doped PoPD nanosphere was at 411 nm and 530 nm, the spectrum blue shift can be attributed to the electron-withdrawing effect of F and S. On the other side, the emission peak of Se-doped PoPD nanospheres were at 594 nm and can be attributed to the electronic donor effect of Se. These nanomaterials can be used as ultra-sensitive fluorescent detection system (ppb level) for Cu 2+ , Ca 2+ , Hg 2+ and H 2 O 2 . The tunable spectrum and sensing performance of this system is interesting and significant.

Photocatalytic CO 2 reduction is a promising strategy for achieving carbon neutrality. Nevertheless, its efficiency is limited by the high energy barrier and severe charge recombination. Herein, Cu–WO 3 hollow sphere hybrids, in which Cu is anchored to the O defects of WO 3 , were fabricated to enable efficient photocatalytic conversion of CO 2 to CO. The oxygen defects in WO 3 promote the preferential deposition of Cu, resulting in the simultaneous exposure of Cu–O defect active sites. In the engineered Cu–WO 3 structure, the confined hollow morphology improves CO 2 adsorption and facilitates the separation of photogenerated electrons and holes. The Cu–O defect centers effectively reduce the overpotential for CO 2 conversion. Consequently, the synthesized Cu–WO 3 catalyst demonstrates excellent and stable photocatalytic CO 2 reduction activity, achieving a CO production rate of 1518 μL g –1 h –1 in the absence of a sacrificial agent, which is 5.2 times greater than that of pristine WO 3 . This study provides new insights into defect modulation for designing highly efficient photocatalytic materials.

Amorphous ZSM-5 was facilely synthesized by simply tuning the aqua ammonia amount and used as support of Mo-V-O for aerobic oxidation desulfurization. It was found that both geometric and electronic effects help to enhance the catalytic performance. Geometrically, the amorphous ZSM-5 could better disperse the metals due to its higher specific area. Electronically, the amorphous ZSM-5 could enable V to enrich electrons availing for oxygen activation to superoxide radical thanks to its low work function. The superoxide radical combines with Mo to form peroxide and then oxidize the sulfur-containing substrates. 100% desulfurization can be realized at 80°C for model oil with sulfur content of 500 ppm over the amorphous ZSM-5 supported Mo-V-O catalyst. This study provides inspiration for designing efficient catalysts for aerobic oxidation desulfurization.

Fifteen new dicaffeoylspermidine derivatives, lycibarbarspermidines A–O (1–15), were isolated from the fruit of Lycium barbarum (wolfberry). The structures were unambiguously determined by spectroscopic analyses and chemical methods. Dicaffeoylspermidine derivatives, a rare kind of plant secondary metabolites, are primarily distributed in the family of Solanaceae. Only six compounds were structurally identified, and all of them are acyclic aglycones. Compounds 1–15 are the first glycosidic products of dicaffeoylspermidine derivatives, and compounds 14–15 are the first cyclization products of dicaffeoylspermidine derivatives. Moreover, dicaffeoylspermidine derivatives were first isolated and identified from wolfberry. The short-term memory assay on a transgenic fly Alzheimer’s disease (AD) model showed that 1–15 exhibited different levels of anti-AD activity. The oxygen radical absorbance capacity assay revealed that 1–15 all displayed antioxidant capacity. Both anti-AD and antioxidant functions are related to the effects of wolfberry. Therefore, dicaffeoylspermidine derivatives are considered beneficial constituents responsible for the antiaging, neuroprotective, anti-AD, and antioxidant effects of wolfberry.

Prenyltransferases (PTs) play important roles in the biosynthesis and structural diversification of natural products. In the present study, two new PTs were characterized from a medicinal plant Murraya exotica. MePT1 unprecedentedly catalyses the formation of two C-geranylated products 8/6-C-geranylumbelliferone together with a trace product 7-O-geranylumbelliferone from umbelliferone. MePT2 regio-specifically catalyses the formation of C-3 dimethylallylated products from quinolone alkaloids. This is the first report that a plant PT catalyses the simultaneous formation of C- and O-prenylated products, and a plant PT specifically utilizes quinolone alkaloids as prenyl acceptors. The results not only provide important insight into the functional diversity of plant PTs and the biosynthesis of the prenylated coumarins, quinolone and carbazole alkaloids in Murraya plants, but also pave the way for the overproduction of the prenylated coumarins and alkaloids using metabolic engineering approaches.

An instant dissolving W/O polymer prepared via reverse-phase emulsion polymerization. • An ultra-high acid resistance polymer formed from water-soluble hydrophobic monomers. • Integrated application for drag reducing and acidic thickening. • Quantum chemistry is used to clarify the mechanisms of dissolution and acid tolerance. Despite the considerable potential of multistage alternating acid fracturing Technique for unconventional tight reservoir stimulation, the integration of acid-thickening and drag-reduction functions within a single additive remains challenging due to the slow dissolution of gelling agents, poor acid resistance of drag reducers, and compatibility issues among multiple chemical additives. Herein, a multifunctional polymer emulsion (PAADT) was rationally designed using a hydrophobic monomer (AT-100) and a high-charge-density symmetric cationic monomer (Dimethyl Diallyl Ammonium Chloride, DMDAAC) to overcome these limitations. PAADT completely dissolved in water and concentrated HCl within 120 s and 330 s, respectively, while retaining viscosity stability for over 120 h and demonstrating exceptional tolerance to multivalent ions. Quantum chemical calculations, including LogP, independent gradient model based on Hirshfeld partition (IGMH), and electrostatic potential (ESP) analysis, revealed that the synergistic effect of polymer-water interactions and electrostatic repulsion governs the dissolution behavior and acid-salt resistance of PAADT. This work establishes a structure–property relationship between monomer architecture and macroscopic performance, providing a molecular design strategy for developing multifunctional polymers for complex environments.

C-lignin, a natural biopolymer of caffeyl alcohol subunits linked by benzodioxane motifs, is an ideal feedstock for direct catechol production. However, its hydrogenolysis is hindered by the high bond dissociation energies and steric congestion of vicinal C–O bonds in benzodioxane structures. Here, we report a low-loaded Co–Zn dual single-atom catalyst (Co SA –Zn SA @NC) that enables efficient C-lignin hydrogenolysis, achieving 84.6% catechol yield, 82% selectivity toward 4-propylcatechol, and a turnover number five times higher than precious Ru/C, attributing to the synergistic effect of the dual atomic sites. The major product, 4-propylcatechol, can be readily purified and upgraded into diverse value-added molecules. Mechanistic investigations reveal that the Zn and Co species, acting as the directing and active centers, respectively, synergistically drive the quasi-concerted cleavage of the vicinal C–O bonds. This work presents an atomically dispersed non-precious metal catalyst for C-lignin hydrogenolysis, providing a sustainable route to well-defined aromatics.

Fluorescent corrosion indicators can identify underlying corrosion on metallic substrates by detecting metal ions resulting from corrosion processes. Nevertheless, the direct incorporation of fluorescent probes into the coating may result in numerous adverse effects. To maximize effective application, encapsulating these probes in specific carriers is considered to be a viable technique. In this work, the design and application of a new fluorescent probe were reported, which contains o-benzylaminophenol (BC) as fluorophores and nanomesoporous silica (MSP) as carrier. MSP, characterized by an average particle size of 90 nm, was synthesized using a sol-gel process. BC was synthesized, which exhibited yellowish-green fluorescence upon the addition of aluminum nitrate, methanol, and water. A novel intelligent container with the function of early corrosion warning was developed by incorporating BC into the MSP carrier by vacuum impregnation. BC@MSP smart containers were included in the solvent-based polyurethane coatings and applied on 2024-T3 aluminum alloy. The coating is engineered to identify corrosion within 24 h following exposure to 3.5 wt.% NaCl by the formation of a complex by BC reacting with metal ions (Al 3+ ). Electrochemical impedance evidenced that the epoxy coating with 4 wt.% BC@MSP presents high corrosion resistance even after 28 d.

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.

Dynamic assessment of renal function has become a critical requirement in clinical and health management. Existing detection methods primarily rely on samples such as blood or urine, posing significant challenges for portable, continuous, real-time monitoring. This study introduces a novel wearable electrochemical biosensing platform based on sweat analysis for non-invasive detection of creatinine, a key biomarker of renal function. The platform employs o-phenylenediamine as a functional monomer to construct a molecularly imprinted polymer recognition layer. Leveraging the multi-point hydrogen bonding interactions provided by its o-diaminic groups, this layer forms strong and specific bonds with creatinine, endowing the sensor with high molecular specificity and anti-interference properties. The system integrates a flexible skin-adhesive interface, an electrochemical detection unit, and a pentagonal star-shaped sweat collection module. It induces localized sweating at rest via built-in electrodes, enabling efficient transport and real-time analysis of fresh sweat. The sensor exhibits excellent linear response characteristics across a concentration range of 0.1 to 400 μM, with two linear regions, both showing correlation coefficients R 2 > 0.99. The platform demonstrated stable detection performance in authentic human sweat samples. Tests evaluating circadian variations in serum creatinine and the impact of protein intake confirmed the sensor's ability to capture fluctuations linked to dietary intake and physiological rhythms. This validates its feasibility for non-invasive, dynamic monitoring of renal function. This wearable device platform shows significant potential as a sweat biomarker monitoring tool, offering possibilities for convenient tracking and personalized management of kidney health.
