Cuproptosis and ferroptosis are difficult to synergize in tumor suppression due to their spatiotemporal asynchrony and mechanistic dispersion. Therefore, we proposed a new paradigm of Ferroptosis-Cuproptosis self-recycling. An iron‑sulfur cluster (Fe-S) metabolic collapse was constructed by hyaluronic acid (HA)-functionalized bimetallic nano-enzymes (HA@CuCo-NC) to initiate this tumoricidal mechanism. HA@CuCo-NC specifically accumulates in osteosarcoma cells through HA-mediated targeting. The multi-enzyme activity triggers a surge of reactive oxygen species (ROS) in the tumor microenvironment, which, along with Co 2+ , induces ferroptosis. This leads to severe mitochondrial damage and glutathione (GSH) depletion, which in turn activates the cuproptosis cascade. Cuproptosis causes Fe-S protein degradation and Fe 2+ release into the labile iron pool (LIP) by inhibiting Fe-S cluster formation and dihydrolipoamide acetyltransferase (DLAT) oligomerization. The released Fe 2+ enhances oxidative stress and promotes membrane disassembly via the Fenton reaction. The two act synergistically to form a dynamic self-reinforcing cycle: Ferroptosis-related mitochondrial damage exacerbates the toxicity of Cu 2+ . Cuproptosis-released Fe 2+ further activates ferroptosis. In vivo experiments demonstrated that HA@CuCo-NC significantly inhibited the growth of osteosarcoma in situ without causing systemic toxicity. This research introduces a novel approach to treating solid tumors by reconstructing the metabolic interaction network of copper and iron.

The incorporation of L-3,4-dihydroxyphenylalanine (L-DOPA) residues in mussel-like biomimetic copolymers has drawn great attention due to their adhesive properties. In this work, a series of temperature-sensitive and hyperbranched poly(amino acid)s containing different functional side groups (catechol, guanidyl, mercapto and double bond) were designed and synthesized by the ring-opening polymerization of N-carboxy-α-amino acid anhydride (NCA), using a temperature-sensitive and multi-hydroxyl end pluronic L-31 as the initiator in this process. The tissue adhesive properties of these copolymers were evaluated by tensile strength tests on wet pork skin. We found that the topological structure, side groups of copolymers, adhesive temperature and cure time had influence on the wet adhesive strength, especially side groups. While only L-DOPA was incorporated into copolymeric chains, the wet adhesive strength was about 106 kPa. With guanidyl, mercapto and double bonds incorporated into copolymeric chains, an obvious increase in the wet adhesive strength was observed. Additionally, the wet adhesive strength improved by about 20 kPa at body temperature (37 °C) as compared to that at room temperature (25 °C). Meanwhile, we found that it has good biocompatibility and degradability through its cytotoxicity and degradation tests.

Layered tin monosulfide (SnS) is a promising anode material for sodium-ion batteries because of its high theoretical capacity of 1020 mA h g–1. Its large interlayer spacing permits fast sodium-ion transport, making it a viable candidate for sodium-ion capacitors (SICs). In this work, we designed and synthesized oriented SnS nanosheets confined in graphene in the presence of poly(diallyl dimethyl ammonium chloride) by electrostatic self-assembly during hydrothermal growth. SnS nanosheets growing along (l00) and (0l0) directions are suppressed because of the confinement by graphene, which exhibit smaller thickness and particle size. These nanostructures expose abundant open edges because of the presence of Sn4+–O, which offers rich active sites and Na+ easy transport pathways. Vacancies formed at these edges along with S and N codopants in the graphitic structure synergistically promoted Na+ surface adsorption/desorption. Such nanocomposites with SnS nanosheets confined by N,S codoped graphene demonstrated significantly enhanced pseudocapacitance. The SICs delivered excellent energy densities of 113 and 54 W h kg–1 at power densities of 101 and 11 100 W kg–1, respectively, with 76% capacity retention after 2000 cycles at 1 A g–1.

The poor electronical conductivity and large volume change of nano-silicon anode has seriously hindered its further application. To overcome these drawbacks, we employed the S-doped multiwalled carbon nanotubes (SCNTs) as the conductive additive to fabricating a scaffolded framework for the first time. The as-assembled Si anode with 5 wt% SCNTs (Si@C-5SCNTs) shows a large specific capacity of 939 mA h g −1 at 2 A g −1 within 0–1 V, significantly higher than that of Si@C (466 mA h g −1 ) and Si@C-5CNTs (720 mA h g −1 ), showing a superior rate performance. Besides, it shows higher initial coulombic efficiency, Li-ion diffusion coefficient, cycling performance, and smaller volume change than that of Si@C and Si@C-CNTs at room temperature. Even at 40 ℃, the Si@C-5SCNTs anode still show a superior rate performance (1842 and 819 mAh g −1 at 0.05 and 2 A g −1 , respectively) and cycling stability (83.6% capacity retention) than that of Si@C and Si@C-5CNTs. To better explain the significantly enhanced electrochemical performance of Si anode both room and high temperature conditions, both the chemo-mechanical coupling and internal temperature distribution models have been rational constructed, and further demonstrated that the SCNTs can effectively buffer the volume expansion and reduce the internal local temperature rise.

Among many lithium secondary batteries, lithium–sulfur batteries stand out because of their high theoretical specific energy, low cost, non-toxicity and the fact that they cause no environmental pollution. However, due to poor electronic and ionic conductivity, shuttle effect, lithium dendrites and other defects, it remains a big challenge to achieve large-scale application of lithium-sulfur batteries. Here we report an all-solid-state lithium–sulfur battery based on Li-argyrodite Li6PS5Cl solid-state electrolytes through a slurry-coating method. Li6PS5Cl with a high ionic conductivity of 1.3 × 10–3 S cm−1 at room temperature is used as the solid electrolyte and the ion conductive additive in the electrode. The sulfur-based composite cathode is fabricated through a slurry-coating process by dispersing sulfur, Li6PS5Cl, ethyl cellulose, and carbon black in 1,3-dioxolane (DOL). This method can disperse the Li6PS5Cl around sulfur particles well, and the solvent does not react with any component of composite cathodes during preparation. The battery delivers a high discharge capacity of 962 mA h g−1 at room temperature for the first cycle at 80 mA g−1. While the Coulombic efficiency is approximately 99.5% during 100 cycles. This work provides a new insight into the combination method between the sulfide-type SSEs and sulfur cathodes, which is critical to the electrochemical performance of all-solid-state lithium-sulfur batteries.

Spirulina was used for the first time as a raw nitrogen-doped porous carbon source to synthesize carbon/sulphur (carbon/S) composite cathodes for lithium-sulphur batteries. The composites consisting of sulphur and spirulina-derived carbon with micro- and meso-pores showed an obvious carbon encapsulating sulphur structure. The carbon/S cathodes exhibited much better electrochemical performance than pristine sulphur, delivering an initial discharge capacity of 662 mAh g −1 with nearly 60% capacity retention after 100 cycles at 1 C current density (1670 mA g −1 ). The improved electrochemical stability of the composites can be ascribed to the synergistic effects between the encapsulation of sulphur by spirulina-derived carbon and adsorption of polysulfides on N doped carbon lattice. These effects successfully prevented or retarded the shuttle effect of sulphur cathodes.

To effectively harness solar energy, the rational construction and development of full-spectrum photocatalysts has become an appealing challenge. In this study, a novel full-spectrum responsive FeS 2 /Mn 0.3 Cd 0.7 S (FS/MCS) S-scheme photocatalyst was obtained by attaching FeS 2 nanoparticles with excellent photothermal properties on Mn 0.3 Cd 0.7 S nanorods. The photocatalytic hydrogen production rate of the optimal FS/MCS composite was 52.017 mmol·g −1 ·h −1 under full-spectrum irradiation, which was 3.88 times that of pure MCS. Based on the experimental results and density functional theory (DFT) calculations, the enhanced photoactivity of FS/MCS was attributed to the synergetic effects of photothermal and S-scheme heterojunction. The photothermal effect of FeS 2 could convert the near infrared light to heat, which elevated the local temperature of photocatalyst particles, thereby promoting the photocatalytic reaction. Meanwhile, the S-scheme heterojunction between FeS 2 and Mn 0.3 Cd 0.7 S accelerated the charge transfer and suppressed the recombination of electron-hole pairs, thereby enabling efficient charge separation while maintaining high redox potentials. This work offers a novel perspective on constructing a full-spectrum-driven photothermal-assisted photocatalytic H 2 evolution system though the dual effects of photothermal and heterojunction.

A benign approach for efficient preparation of poly(ether sulfone) (PES) ( η
inh = 0.10−0.31 dL⋅g −1 ) has been presented by using ionic liquid (IL)/zwitterion (ZI) as reaction medium. It has been found that the interaction between 4,4′-dihydroxydiphenylsulfone (Bisphenol-S) and ZI at elevated temperatures results in efficient reduction of dehydration time, which is confirmed by TGA curves, melting point of the mixture and FTIR spectra. Furthermore, no agglomeration is observed at dehydration stage, which is attributed to the high solubility of Bisphenol-S dipotassium salt in IL/ZI. This also makes the polymerization temperature (150 °C) much lower than a conventional method (220−300 °C). In order to demonstrate the efficiency of IL/ZI as reaction medium, the polymerization was also performed in sulfolane under the same reaction condition as that in IL/ZI.

Lithium-ion batteries (LIBs) attract widespread attention as promising energy storage devices owing to their superior energy density, excellent cycle life, and absence of memory effect. However, they still encounter challenges in high-rate performance and structural stability, necessitating further optimization. This study focuses on a composite anode material constructed from black phosphorus (BP), tungsten disulfide (WS 2 ), and ultra-high-purity whisker carbon nanotubes (UWCNTs) (BP-WS 2 -UWCNTs). The research investigates the regulatory effects of phosphorus–carbon (P–C) and phosphorus–sulfur (P–S) bonds at the material interface on electrochemical performance. Characterization indicates the establishment of P–C and P–S bonds at the composite interface, which enhance structural integrity and improve electron/ion transport capabilities. Electrochemical performance evaluations validate the combined effect of these interfacial bonds: at 2.0 A g −1 , the BP-WS 2 -UWCNTs anode delivers 605.8 mAh g −1 for 2000 cycles, and retains 252.2 mAh g −1 after 3000 cycles even at 15.0 A g −1 , exhibiting remarkable rate performance and prolonged cycling durability. In practical applications of LIBs, the composite anode maintains robust structural integrity and outstanding electrochemical performance. This work highlights that the combined effect of interfacial P–C and P–S chemical linkages effectively facilitates lithium-ion diffusion and stabilizes the electrode structure, offering valuable insights and viable strategies for advancing high-capacity anode design in LIBs.

Tin selenide (SnSe), as a direct bandgap (1.1–1.3 eV) photovoltaic absorber material, has a theoretical power conversion efficiency comparable to commercial thin-film solar technologies. However, the efficiency of experimentally fabricated SnSe solar cells is significantly lower than the theoretical value, mainly constrained by two major bottlenecks: (1) the bulk defects leading to carrier recombination and (2) the bandgap mismatch at the interface. Additionally, the environmental toxicity of the CdS and its parasitic absorption of short-wavelength light also limit the sustainable development. This study proposes and systematically investigates the all-inorganic structure of FTO/Zn(O,S)/SnSe/Carbon. Replacing traditional CdS with Zn(O,S) can achieve tunable bandgaps and eliminate Cd toxicity. Through SCAPS-1D simulation, the thickness and carrier concentration of each functional layer are optimized, and the influences of bulk defect density, interface defect density, and resistance on device performance are analyzed. Meanwhile, the S content in Zn(O,S) is adjusted, and the sulfur enrichment (S content of 70%) induces the best conduction band offset (ΔEc = 0.05 eV). The resulting optimal device exhibits an efficiency of 22.46%, Voc = 0.90 V, Jsc = 30.06 mA/cm2, and FF = 83.39%. This work establishes a universal paradigm combining nontoxic material selection (Zn(O,S)/carbon), interface thermodynamic control, and defect passivation strategies, paving the way for the commercialization of sustainable thin-film solar cells.

Inhibiting photogenerated electron-hole recombination to enhance interfacial electron transfer is crucial for improving photocatalytic CO₂ reduction. Three heterojunction photocatalysts (SiW 11 Co@TiO 2 , SiW 11 Ni@TiO 2 and SiW 11 Cu@TiO 2 ) were prepared via solvothermal self-assembly. Through UV–vis–DRS, Mott-Schottky analysis and radical trapping experiments, we determined that SiW 11 Co@TiO 2 forms a type-I heterojunction while SiW 11 Ni@TiO 2 and SiW 11 Cu@TiO 2 form S-scheme heterojunctions with superior catalytic activity. UPS analysis revealed that the work function difference between SiW 11 Cu and TiO 2 (1.30 eV) exceeds that of SiW 11 Ni and TiO 2 (1.08 eV), correlating with enhanced EPR signals and faster interfacial electron transfer for SiW 11 Cu@TiO 2 . SiW 11 Cu@TiO 2 achieved optimal CO 2 reduction performance with CO and CH 4 yields of 84.12 and 12.32 μmol·g −1 ·h −1 , respectively, representing 1.38 times higher electron yield than SiW 11 Ni@TiO 2 . This work demonstrates that modulating energy band positions to construct S-scheme heterojunctions with enhanced built-in electric fields provides an effective strategy for designing high-performance CO₂ photocatalysts.
