Hollow carbon spheres (HCSs) have emerged as promising anode materials for lithium-ion batteries (LIBs), yet their practical application is hindered by intrinsic limitations. Excessive internal voids reduce the tapped density and volumetric energy density, while poor interparticle connectivity increases transport resistance and compromises rate capability. Here, we present a series of nitrogen-doped hollow carbon sphere clusters (HCSCs) with varying hollow diameters (20 nm, 100 nm, and 300 nm), achieved via a combined spray-drying and solution-stirring approach. The 20-HCSCs with ultra-small cavities (20 nm) markedly enhances tap density, while cluster-level interconnectivity establishes continuous pathways for efficient Li + and electron transport, thereby enabling rapid charge/discharge kinetics and high volumetric capacity. Consequently, the 20-HCSCs electrodes exhibit an exceptional reversible capacity of 447.3 mAh cm -3 after 90 cycles at 0.2 C, surpassing that of 100-HCSCs, 300-HCSCs electrodes and conventional graphite electrodes (around 372 mAh cm -3 ), and demonstrate remarkable high-rate cyclability, retaining 68.5 mAh cm -3 after 3000 cycles at 50 C. The ultrahigh volumetric capacity mitigates the volumetric penalty typically imposed by hollow structures, offering a viable strategy to reconcile high capacity, fast-charging capability, and competitive volumetric performance in carbonaceous anodes.

Triple-negative breast cancer (TNBC) remains a formidable clinical challenge characterized by its aggressive metastasis and a scarcity of effective treatment strategies. However, photodynamic therapy (PDT) is severely limited by the hypoxic tumor microenvironment, and photothermal therapy (PTT) is restricted by the low photothermal conversion efficiency of the photothermal agents. The photosensitizer IR780 has received widespread attention due to its dual potential in both PDT and PTT, but it suffers from insufficient photostability and is prone to fluorescence quenching. To overcome these challenges, this study constructed a multifunctional self-oxygen-supplying biomimetic nanoparticle platform, named CaO2@PDA-IR780@CM (CPIC). In this system, calcium peroxide (CaO2) decomposes in an acidic tumor microenvironment and releases oxygen in situ, effectively alleviating tumor hypoxia and enhancing the PDT efficacy mediated by IR780. Loading IR780 onto polydopamine significantly improved its stability and photothermal performance, achieving a photothermal conversion efficiency of 54.5%, which represents a significant enhancement compared with free IR780. The nanoparticle surface was coated with homologous tumor cell membranes, endowing it with tumor-specific targeting ability. In an orthotopic 4T1 tumor-bearing mouse model, CPIC showed significantly stronger intratumoral fluorescence signals compared with free IR780 and the control nanoparticles without cell membrane coating, thereby confirming its superior tumor targeting efficiency. Furthermore, the combination of PDT/PTT mediated by CPIC significantly suppressed primary tumor growth and effectively inhibited the formation of pulmonary metastatic nodules, highlighting its remarkable translational potential for TNBC treatment.

Spectral information, reflecting the interaction between light and matter across different wavelengths, is essential for identifying material properties and environmental changes. To meet the demand for compact spectral sensors, we constructed a type-I band-aligned MoTe 2 /Te van der Waals (vdW) heterostructure through precise band structure design, where the drain–source voltage ( V ds ) electrostatically tunes interfacial band alignment to complement gate voltage ( V gs ) modulation. By synergistically tuning the V gs and V ds , we achieved a wavelength-dependent photoresponse and constructed a spectral responsivity matrix. Integrated with an attention-guided multilayer perceptron (MLP) algorithm that incorporates the device's responsivity as prior physical information, the device functions as a miniaturized spectrometer, demonstrating narrowband spectral reconstruction with an optimal resolution of 6 nm across a broadband range from 500 to 780 nm at room temperature. The noncentrosymmetric crystal structure of Te also endows the device with the capability of simultaneous polarization discrimination. This work provides a promising approach toward multifunctional on-chip spectrometers capable of simultaneous spectral and polarization analysis.

PB@MSN-CIN nanoparticles enabled CIN release with NIR-triggered photothermal conversion. • S/P-HK bilayer films combined PB@MSN-CIN-loaded P-HK inner layer with a hydrophobic SHL-QCT outer layer. • Regulating the SHL-QCT layer thickness improved moisture barrier, UV shielding, and photothermal retention of the bilayer films. • Under NIR treatment, the optimized S/P-HK film suppressed microbial growth, browning, and water loss of fresh-cut Benincasa hispida . Fresh-cut vegetables are highly susceptible to microbial growth, enzymatic browning, and moisture loss, creating a need for environmentally sustainable active packaging with effective barrier and antimicrobial functions. In this study, a multifunctional bio-based bilayer film (S/P-HK) was developed using the thickness of the hydrophobic outer layer as a key design variable. The inner active layer (P-HK) comprised a konjac glucomannan/hydroxyethyl cellulose matrix containing cinnamaldehyde (CIN)-loaded mesoporous silica nanoparticles coated with Prussian blue (PB@MSN-CIN), whereas the outer layer was composed of quercetin-containing shellac (SHL-QCT). SEM revealed a compact bilayer structure, while FT-IR, XRD, and TGA indicated intermolecular interactions and good thermal stability. Increasing the thickness of SHL-QCT layer enhanced moisture-barrier performance and heat retention under near-infrared (NIR) irradiation. Among which, the S20/P-HK film exhibited nearly complete UV shielding, strong antioxidant activity (DPPH and ABTS radical scavenging rates >80%), excellent antibacterial activity (antibacterial rates >99.99% against Escherichia coli and Staphylococcus aureus ), and controlled release of CIN. During preservation of fresh-cut Benincasa hispida , the S20/P-HK film with NIR irradiation significantly inhibited microbial growth, suppressed the browning index to 0.90 ΔOD₄₂₀·mL/g, and restricted weight loss to 0.26% over 10 days. These findings demonstrate a promising thickness-regulated bilayer design that integrates moisture-barrier protection, NIR-responsive CIN release, and photothermal antibacterial activity for active packaging. Future studies should validate the applicability of S/P-HK films to other perishable foods and evaluate their antifungal efficacy.

Sacrificial template strategy builds ZnO 2 @Hemin-ZIF-8 core-shell structure. • The seamless ZIF-8 shell prevents premature ZnO 2 leakage at physiological pH. • Hierarchical ZnO 2 @Hemin-ZIF-8@PB (ZHZHP) enables on-demand H 2 O 2 release. • ZHZHP enables dual-nanozyme cascade-based CDT and PTT to eradicate bacteria. • ZHZHP orchestrates anti-inflammation and angiogenesis to accelerate wound healing. Chemodynamic therapy (CDT) has emerged as a promising strategy for combating bacterial infections; however, the scarcity of endogenous H 2 O 2 within infection sites often bottlenecks therapeutic efficacy. Herein, a pH-responsive, H 2 O 2 self-supplying nanoplatform is meticulously engineered for spatiotemporally controlled chemodynamic–photothermal antibacterial therapy. This platform leverages ZnO 2 nanoparticles dual-role cores and sacrificial template to drive the in situ epitaxial growth of dense ZIF-8 shells (optionally encapsulated with Hemin), yielding the core–shell ZnO 2 @ZIF-8 (or ZnO 2 @Hemin-ZIF-8) intermediate. Stepwise surface engineering with hyaluronic acid (HA) and Prussian blue (PB) leads to the formation of a hierarchical core–shell structured ZnO 2 @Hemin-ZIF-8@HA@PB nanoplatform (ZHZHP). Under neutral physiological conditions, ZHZHP exhibits excellent stability as the interracially-bonded ZIF-8 shell effectively shields the ZnO 2 core from premature hydrolysis. Conversely, within the weakly acidic infection microenvironment, ZHZHP undergoes programmed disassembly, triggering the on-demand release of H 2 O 2 . Simultaneously, Hemin and PB act as peroxidase mimics to catalyze the conversion of liberated H 2 O 2 into highly toxic hydroxyl radicals (‧OH) via dual nanozyme cascades, while the PB component provides robust photothermal conversion under 808 nm NIR irradiation. This synergistic CDT/PTT approach achieves complete eradication of S. aureus and E. coli at an extremely low concentration of 50 μg mL −1 and demonstrates remarkable efficacy in disrupting both immature and mature biofilms. In vivo assays further confirm that ZHZHP significantly accelerates infected wound healing through potent antimicrobial and anti-inflammatory activities, alongside the promotion of angiogenesis. With high biocompatibility and negligible toxicity, ZHZHP represents a sophisticated strategy for the clinical management of refractory wound infections.

Surface-enhanced Raman scattering (SERS) is a powerful tool for rapid on-site detection of pesticide residues, but its performance heavily relies on the substrate. Herein, a gelatin‑silver nanocube (Ag NC) composite hydrogel SERS substrate was developed via mild EDC-NHS crosslinking coupled with low-temperature gelation. The three-dimensional porous hydrogel efficiently enriches target molecules, while the sharp edges of Ag NCs generate abundant electromagnetic hotspots. Using rhodamine 6G as a probe, the optimized substrate (20% gelatin, Ag NC/gelatin volume ratio 3:1) exhibited good uniformity, reproducibility, and stability. For thiram detection, a linear response was obtained from 10 −4 to 10 −7 M with a limit of detection (LOD) of 4.45 × 10 −8 M in standard solution. Practical applicability was demonstrated in orange juice, where thiram was detected down to 1.0 × 10 −6 M (LOD = 4.78 × 10 −7 M) with recoveries of 96.9–97.9%. This work provides a gelatin-based, stable and sensitive SERS platform for food safety monitoring.

Integrating pollutant detection and degradation into a single material platform is highly desirable for the efficient treatment of dye-contaminated wastewater. However, simultaneously achieving sensitive detection and efficient photocatalytic activity remains challenging because these functions involve distinct interfacial processes. In this work, an Ag NPs@Cu-V 2 O 5 hybrid was prepared through wet-chemical synthesis and calcination of Cu-V 2 O 5 , followed by ultrasonic coupling with preformed Ag nanoparticles. Cu incorporation modulated the local electronic environment of V 2 O 5 , while the supported Ag nanoparticles provided plasmonic SERS-active sites. XPS binding-energy shifts were consistent with interfacial electronic redistribution, FDTD simulations revealed pronounced local-field amplification around the Ag nanoparticles, and energy-level analysis indicated accessible interfacial charge-transfer pathways under 532 nm excitation. Using colorless, non-resonant 4-MBA as a control probe, the hybrid produced a higher Raman response than the Ag NP reference under equivalent Ag loading, indicating that the enhancement was not solely dependent on the molecular pre-resonance behavior of MB. The hybrid enabled MB detection down to 1 × 10⁻⁹ mol L⁻¹ , with good spatial uniformity and approximately 80% signal retention after 28 days. After correction for dark adsorption, it achieved an MB degradation efficiency of 82.3% after 60 min of visible-light irradiation and exhibited higher photocatalytic activity than pristine V 2 O 5 and Cu-V 2 O 5 . These results demonstrate a plasmonic–semiconductor platform that integrates SERS sensing and photocatalytic remediation through Ag-induced local-field amplification, Cu-related electronic modulation, and Ag/Cu-V 2 O 5 interfacial interactions.

Collagen is an ideal raw material for biological fibers, yet achieving long-range structural order and the resultant high-strength fibers without toxic crosslinkers remains a major challenge. This work integrates ultrasonic fragmentation with dialysis concentration to induce a stable lyotropic liquid crystalline (LC) collagen dope at a concentration as low as 3.3%, which is significantly lower than previously reported. Ultrasonic treatment reduced collagen fragment length to 10–30 nm, lowering steric hindrance and enhancing molecular mobility, thereby promoting nematic LC formation. Rheological analysis revealed that at 3.7%, the spinning dope exhibited a characteristic viscosity plateau in the low shear rate range of 1–5 s −1 , indicating shear-induced alignment of nematic LC domains, which defines the optimal spinning window. Using 4.0% LC dope and an optimized ethanol flow rate of 0.30 mL/min in microfluidic spinning process, the resultant collagen fibers achieved a high tensile strength of 2.21 cN/dtex and a thermal denaturation temperature of 120.8 °C. Increasing the spinning dope concentration progressively reduced lateral molecular packing distance, transformed the fiber surface from grooved to smooth, and enhanced thermal stability. This study establishes a rational, crosslinker-free strategy to fabricate high-performance pure collagen fibers with superior mechanical and thermal properties, providing critical theoretical and technical support for their application in absorbable surgical sutures and regenerative medicine.

Aqueous zinc ion hybrid capacitors (ZIHCs) typically pair a battery-type Zn anode with a capacitor-type porous carbon cathode. Their capacity is conventionally thought to be limited by the intrinsic electric double-layer (EDL) capacitance and pseudocapacitance arising from the porous structure and surface chemistry of the cathode. This longstanding view has constrained the achievable energy density of ZIHCs. In this work, we challenge this paradigm by demonstrating that charging at high voltage substantially enhances the capacity of commercial cathodes in a 2 M ZnSO 4 electrolyte. Leveraging this insight, we develop two simple strategies to significantly increase the energy density of ZIHCs. An ex situ approach nearly doubles the capacity of a commercial cathode, yielding an order of magnitude increase in the specific energy E total based on the total active mass of anode and cathode when integrated into a Zn-limited configuration. Alternatively, an in situ strategy, which directly charges the device to a high voltage, achieves comparable enhancement while simplifying fabrication. Both strategies deliver exceptional cycling stability (over 60,000 cycles at 5.0 A g −1 ) and are successfully validated in pouch cell prototypes. Overall, this work provides a deeper mechanistic understanding and offers simple, low-cost routes to high-energy-density aqueous ZIHCs.

Biomineralization of bacterial as a ultrasound (US)-triggered CO generator. • Engineered bacteria can decompose through acid-response in tumor microenvironment. • Self-supplying H 2 O 2 , amelioration of hypoxia, Ca 2+ -induced mitochondria damage. • US-triggered CO release for apoptosis in tumor cells. • Activating anti-tumor immune responses for significant inhibition of tumor growth. Carbon monoxide (CO) gas therapy is emerging as a highly promising strategy in cancer treatment. However, the tumor-targeted delivery and on-demand release of CO remain formidable challenges, and monotherapeutic efficacy is inherently limited. To address these issues, we report a self-guided “CO-releasing bomb” constructed by armoring Escherichia coli ( E. coli ) with 3-hydroxyflavone-D-alanine (HF-D-Ala) and calcium peroxide (CaO 2 ) nanoparticles (EHC). Upon reaching the acidic, hypoxic tumor microenvironment (TME), CaO 2 instantly generates Ca 2+ and H 2 O 2 ; the bacterium then self-catalyzes H 2 O 2 to produce a local O 2 burst. Subsequent ultrasound irradiation triggers HF-D-Ala to liberate a high concentration of CO owing to the O 2 -rich environment, selectively damaging tumor-cell mitochondria and inducing apoptotic death. Moreover, the O 2 generation alleviates tumor hypoxia and reverses the immunosuppressive TME. Concurrently, E. coli antigens promote dendritic cell maturation and enhance T-lymphocyte recruitment and infiltration. In vivo studies demonstrate that the EHC under US irradiation significantly suppresses tumor growth and potently activates antitumor immunity. These findings provide compelling evidence to support the potential application of combined CO gas therapy and immunotherapy for in vivo tumor treatment.

A novel wet leaching process was proposed for recovering FePO 4 from lithium extraction slag. • H₂SO₄ and (NH₄)₂SO₃ were used as leaching and reduction reagents, respectively. • The leaching efficiency of FePO 4 reached up to 99.5% under optimized operation conditions. • The purity of final product met battery-grade standards with an overall recovery efficiency above 95%. • Hundred-kilogram-scale experiments demonstrated the feasibility and operational stability of the process A novel hydrometallurgical leaching process based on a H₂SO₄-(NH₄)₂SO₃ system for the efficient and low-cost recovery and regeneration of battery-grade iron phosphate (FePO₄) from lithium extraction slag (LES) was developed. Under optimized operating conditions (sulfuric acid concentration of 1 mol/L, ammonium sulfite dosage of 0.125 g/g LES, solid-to-liquid ratio of 160 g/L, reaction temperature of 50 °C and reaction time of 120 min), the process achieved highly efficient leaching of FePO₄ with a leaching efficiency exceeding 99.5%, significantly reducing alkali consumption in subsequent steps and the overall process cost. Through precise control of the precipitation pH, highly selective FePO₄ precipitation and effective impurity separation were realized. The purity of the final product met battery-grade standards, with an overall recovery efficiency above 95%. Through a comparative study of the leaching kinetics of Fe 2+ and Fe 3+ , it was revealed that the reductive leaching process is governed by a chemical reaction-controlled model, in which the acid-induced dissolution of the FePO₄ lattice (E a = 51.29 kJ/mol) poses a higher kinetic barrier compared to the reduction reaction, serving as the rate-determining step for the overall process. Thermodynamic analysis and phase evolution tracking elucidated the mechanisms of efficient FePO₄ dissolution and selective precipitation, providing a theoretical basis for precise pH control to selectively recover Fe 3+ while suppressing the co-precipitation of Al, Mn, Ni, and Ca impurities. Crucially, the process enabled closed-loop circulation of the leaching medium by converting it into ammonium sulfate, thereby enhancing resource efficiency alongside environmental and economic benefits. Furthermore, hundred-kilogram-scale experiments demonstrated the feasibility and operational stability of the process. Compared with alternative routes, this approach offers a substantial advantage in raw material cost control. Its core unit operations align well with existing industrial FePO₄ production lines without requiring major retrofitting, highlighting its strong potential for industrial integration. In summary, the proposed recycling strategy provides a viable, efficient, and green technological route for FePO₄ valorization from lithium extraction slag.

The
surface engineering of nanomaterials is crucial for addressing
persistent issues related to their dispersion stability in base oil.
In this study, the superfine boehmite (AlOOH) nanomaterials were successfully
synthesized and subsequently modified by hexadecyltrimethoxysilane
to achieve their dispersion stability in poly α olefin 8 (PAO8)
for at least 35 days. This oil-soluble AlOOH was employed alongside
molybdenum dialkyldithiophosphate (MoDTP) as additives in PAO8 to
effectively reduce friction and wear. The results demonstrated that
the composite additives of MoDTP and oil-soluble AlOOH exhibited remarkable
friction performances in PAO8. Notably, when 1.5 wt % oil-soluble
AlOOH was combined with 0.25 wt % MoDTP, the average coefficient of
friction and wear rate were decreased by 80.93% and 86.34% compared
to base oil, respectively. Meanwhile, the tribological properties
of PAO8 containing the desired composite additive under various sliding
conditions were investigated as well. Furthermore, the synergistic
effect between the oil-soluble AlOOH and MoDTP facilitates the formation
of a robust tribofilm composed of FePO 4 , Fe 2 (SO 4 ) 3 , MoS 2 , FeO, Al 2 O 3 , Fe 2 O 3 , MoO 3 , and
Fe 3 O 4 , ultimately boosting friction-reducing
and wear-resistance effects as well as load-bearing capacity.
