Developing efficient monolith catalysts for photocatalytic CO 2 reduction remains fundamentally challenging due to their inherently sluggish charge transfer. Herein, we report a Co 3 O 4 catalyst with serious agglomeration and meanwhile rich in oxygen vacancies (V O -r-Co 3 O 4 ), which achieves an unexpected superior photocatalytic CO evolution rate of 19.56 mmol h −1 g −1 . Experimental results and density functional theory (DFT) calculations reveal that V O play a crucial role in optimizing the CO 2 reduction pathway. Specifically, the abundant V O create a low-coordination environment around Co atoms, substantially weakening the Co O orbital hybridization. This directly induces a significant downshift of the Co 3 d -band center, effectively alleviating the overbinding of reaction intermediates. Consequently, the energy barriers for both the rate-determining *COOH formation and CO desorption are substantially reduced. This work highlights the importance of local electronic modulation in overcoming the charge transport limitations of monolith catalysts, offering a cost-effective strategy to revitalize such materials for solar energy conversion.

Silicon suboxides (SiO x ) are promising anodes for lithium-ion batteries, but their practical application is hindered by severe volume fluctuation and sluggish (de)lithiation kinetics. Herein, a hierarchical disproportionated-SiO x -based composite, D-SiO x @NC/C@CNTs/rGO-2, consisting of disproportionated SiO x (D-SiO x ) with in situ generated Si/SiO 2 domains, a nitrogen-doped carbon/carbon (NC/C) interphase, and an interconnected CNTs/rGO conductive framework, is constructed through thermal disproportionation, interphase engineering, and multidimensional conductive-network design. Thermal disproportionation induces the in situ formation of Si domains embedded in a SiO 2 buffering matrix, in which Si provides lithium-storage activity while SiO 2 alleviates volume variation and enhances structural stability. Meanwhile, a conformal nitrogen-doped carbon interphase mitigates chemo-mechanical stress and stabilizes the active interface, and the intertwined CNTs/rGO framework builds an efficient conductive network. As a result, the optimized anode delivers a reversible capacity of 876.4 mAh·g −1 after 500 cycles at 0.5 A g −1 , with a capacity retention of 83.7%, while electrode swelling is suppressed to ≈52% versus ≈159% for bare D-SiO x . Operando electrochemical impedance spectroscopy combined with distribution of relaxation times reveals reduced interfacial polarization and faster apparent Li + transport. A pre-lithiated LFP||D-SiO x @NC/C@CNTs/rGO-2 full cell also shows an initial Coulombic efficiency of 96.15% and stable cycling over 200 cycles.

The strong d-p covalent interaction of Mo-P bonds was obtained. • Lattice doping of P into MoS 2 formed Mo-P bonds in 0.2P-MoS 2. • 0.2P-MoS 2 achieved 91.7% tetracycline degradation under LED irradiation. Antibiotic pollution in water calls for sustainable remediation approaches such as photocatalysis. Despite its promising structure and visible-light response, MoS 2 is hindered by rapid carrier recombination, which severely restrict its photocatalytic efficiency. Herein, we reported a strategy of lattice phosphorus doping into MoS 2 to modulate the electronic structure, broaden visible-light absorption, and facilitate charge separation and migration. The optimized 0.2P-MoS 2 achieved 91.7% degradation of tetracycline (30 mg/L) within 80 min under low-power LED irradiation, with a reaction rate constant 5.5-fold higher than pristine MoS 2 . The superior photocatalytic degradation activity for 0.2P-MoS 2 arises from the narrowest band gap (1.21 eV) and accelerated charge carrier migration originated from the strong d-p covalent interactions in the generated Mo-P bonds. Radical scavenging experiments and electron paramagnetic resonance characterizations identified superoxide radicals (•O 2 − ) and holes (h⁺) as the dominant reactive species. Furthermore, possible photocatalytic degradation pathways of tetracycline were proposed over the 0.2P-MoS 2 catalyst. Moreover, the 0.2P-MoS 2 catalyst maintained high activity after five consecutive cycles, demonstrating its excellent stability. This work offers an electronic structure engineering perspective for rational design of MoS 2 -based photocatalysts and provides a viable approach for antibiotic degradation under low-power light sources, holding substantial promise for environmental remediation.

Phototherapy has gained considerable attention in cancer treatment. Molecules with pronounced near-infrared (NIR) absorption are particularly advantageous for laser-induced phototherapy, as their NIR absorption enables deep tissue penetration while minimizing incidental damage to healthy tissues. In this study, we rationally designed and synthesized a non-fused ring A-D-A-type dye (T8IC4F) exhibiting both NIR absorption and fluorescence properties. Through self-assembly of T8IC4F with DSPE-PEG-NH 2 , water-dispersible nanoparticles (NPs) designated as C4@PEG were fabricated. The resulting C4@PEG NPs exhibit NIR absorption and NIR-II fluorescence properties and demonstrate significant therapeutic efficacy. Upon 808 nm laser irradiation (1 W·cm −2 ), these NPs exhibit a singlet oxygen ( 1 O 2 ) quantum yield of 25.9% and a photothermal conversion efficiency of 61%. These properties enable them to mediate both photodynamic and photothermal therapy, leading to robust antitumor efficacy. Moreover, C4@PEG NPs induce immunogenic cell death, facilitate the release of tumor antigens, and activate an antitumor immune response. These findings suggest that C4@PEG NPs could be applied in cancer phototherapy and immunotherapy.

Cu-based electrocatalysts are promising for the electrocatalytic CO 2 reduction reaction (eCO 2 RR) to realize valuable chemicals production. Here, a Mg-doped Cu based electrocatalysts via transient CO 2 pulsed laser (L 4 -Mg/Cu x O) was synthesized for highly selective eCO 2 RR to ethanol (C 2 H 5 OH). The synergistic effect of Mg-doping and transient CO 2 pulsed laser irradiation enables excellent eCO 2 RR performance, realizing Faradaic efficiencies (FE) of 52.2% and 74.1% for C 2 H 5 OH and C 2 products under a high current density of 298.9 mA cm −2 , respectively. Operando Raman spectroscopy and DFT simulations results confirm that Mg-doping strategy suppresses the hydrogen evolution reaction (HER), enhances CO adsorption, elevates local pH and accelerates H 2 O dissociation, which could be beneficial for promoting OC–CO coupling and proton supply in eCO 2 RR. Furthermore, Mg incorporation induces electron delocalization in which electron accumulation on the C atom of *CHCOH intermediate and its enhanced p-d orbital coupling with Cu interface, which stabilizes the C–O bond from breakage and selectively favours the C 2 H 5 OH pathway, thus decoupling the selectivity between C 2 H 5 OH and ethylene. When employed in Li-CO 2 batteries, L 4 -Mg/Cu x O delivers 20480 mAh g −1 discharge capacity and cycling stability over 187 cycles. This work presents a universal strategy for regulating eCO 2 RR selectivity through precise laser energy delivery, demonstrating significant potential for renewable energy conversion and storage.

Although red phosphorus (RP) is a promising photocatalyst, its performance in simultaneous benzyl alcohol (BA) oxidation and H 2 evolution is constrained by undesirable carrier recombination and sluggish surface reaction kinetics. The d–p orbital hybridization, serving as a crucial mechanism for electronic structure regulation, offers an effective strategy to address the aforementioned challenges. Hence, RP is synergistically regulated by defect-rich nickel oxide (NiO x ) and Co single atoms (Co SA ) to construct a dual d−p orbital hybridized photocatalyst (NiO x @RP@Co SA ). In the NiO x @RP@Co SA system, the Ni 3d–P 2p orbital hybridization optimizes the BA adsorption at Ni sites and reducing the C─H bond activation energy barrier. Meanwhile, the Co 3d–P 2p orbital hybridization is conducive to balancing the hydrogen reduction reaction. In situ characterization combined with density functional theory (DFT) calculations confirms that precise regulation of dual d–p orbital hybridization not only enhances charge separation efficiency but also promotes surface reaction kinetics. The 5NiO x @RP@0.2Co SA exhibited superior photocatalytic performance, which is approximately a 15.48-fold enhancements compared to RP. This work not only elucidates the mechanism of dual d−p orbital hybridization but also establishes a novel paradigm for the design of efficient and multifunctional solar-driven catalytic systems.

Wear and oxidation resistance are among the primary requirements for successful and sustainable total joint replacements (TJRs). Both of these factors are major causes of TJRs failure. To address these issues and enhance the service life of TJRs, the effects of vitamin E (VE) and vitamin E-D-sorbitol (VE-DS), which are antioxidants (AOs), on stabilizing ultrahigh-molecular-weight polyethylene (UHMWPE) are presented. These antioxidants were blended with control-UHMWPE at a concentration of 0.3 % by weight and consolidated by compression molding. Wear occurs on the surface, and restricting the crosslinking to a layer on the surface is desirable, as bulk crosslinking reduces the toughness and fatigue strength of the implant. In this study, surface chemical crosslinking of control-UHMWPE, VE-UHMWPE and VE-DS-UHMWPE with dicumyl peroxide (DCP) is presented. The crosslinked density, crystallinity, wear volume, mechanical performance, biocompatibility and oxidation stability assessed by oxidation induction time (OIT) of the UHMWPE blends were characterized through different techniques. The control-UHMWPE blend showed the highest wear resistance but the lowest OIT, while the VE-DS-UHMWPE blend displayed highest crystallinity, best mechanical performance and the highest OIT, exhibiting the synergistic effect of vitamin E and D-sorbitol on the oxidation resistance of UHMWPE.

The construction of oxide/metal composite catalysts is a competent means of exploiting the electronic interactions between oxide/metal to enhance catalytic activity. In this work, we construct a novel heterogeneous composite (Ru/HfO 2 -NC) with Ru/HfO 2 nanoparticles nested in nitrogen-doped porous carbon via a zeolitic imidazole frameworks-assisted (ZIF) co-precipitation and calcination approach. In particular, ZIF guides an in-situ construction of nested configuration and confines the scattered nanoparticles. Strikingly, Ru/HfO 2 -NC exhibits unusual ORR activity, superb durability, and methanol tolerance in 0.1 M KOH solution with high half-wave potential ( E 1/2 ) of 0.83 V and follows a near-4e − reaction pathway. Additionally, the ZAB assembled with cathodic Ru/HfO 2 -NC outputs a power density of 157.3 mW cm −2 , a specific capacity of 775 mA h g Z n - 1 , and a prolonged lifespan of 258 h at 5 mA cm −2 . Meanwhile, the catalyst has demonstrated potential applicability in flexible ZAB. As suggested by experimental results and density functional theory (DFT) analysis, the remarkable property possibly originated from the optimization of the adsorption and desorption of reactive intermediates caused by the reconfiguration of the electronic structure between Ru and HfO 2 .

L-Malic acid is the Active Pharmaceutical Ingredient of the latest generation of compound electrolyte injection (STEROFUNDIN ISO, Germany) and plays a very important role in the rescue of critically ill patients. The optical purity of L-malic acid is a Critical Quality Attributes. A new reversed-phase high performance liquid chromatography (RP-HPLC) method for pre-column derivatization of D-malic acid enantiomer impurity in L-malic acid bulk drug was established. The derivatization reaction was carried out using (R)-1-(1-naphthyl)ethylamine ((R)-NEA) as a chiral derivatization reagent. The Kromasil C18 column was used with a detection wavelength of 225 nm, a flow rate of 1.0 mL·min-1, and a column temperature of 30 °C. The mobile phase was acetonitrile-0.01 mol·L-1 potassium dihydrogen phosphate solution (containing 20 mmol·L-1 sodium heptanesulfonate, adjusted to pH 2.80 with phosphoric acid) (at a ratio of 45:55) and the resolution of D-malic acid and L-malic acid derivatization products reached 1.7. The proposed method possesses the advantages of simple operation, mild conditions, stable derivatization products and low cost. Also it gave better separation and was more accurate than previous methods.

In this study, Fe-rich sludge was pretreated by dielectric barrier discharge (DBD) and used as a Fenton catalyst for the degradation of 2,4-dichlorophenoxyacetic acid (2,4-D) in aqueous solution, where hydrogen peroxide was in situ supplied from a glow discharge plasma (GDP) in contact with the solution. Synergistic mechanism of the two plasmas during 2,4-D degradation was explored. The Fe-rich sludge pretreated by H 2 -DBD could significantly accelerate the 2,4-D degradation as it converted Fe(III) in the sludge to the active Fe(II). 2,4-D can be completely removed in the presence of H 2 -DBD pretreated Fe-rich sludge with 25 min of GDP at pH 0 3.0 and catalyst dosage of 1.0 g/L. Quenching experimental studies showed that both ·OH (oxidative degradation) and ·H (reductive dechlorination) were responsible for 2,4-D degradation. Reducing radicals (such as ·R and·H) formed during GDP can continuously reduce the Fe 3+ back to Fe 2+ , which further promoted the degradation and dechlorination of 2,4-D. The results of three consecutive experiments indicated the stability and reusability of catalyst. This study provides a potential method for the recycle of Fe-rich sludge as a novel and cost-effective catalyst for 2,4-D removal from aqueous environments, which is significant for the terminal disposal of Fe-rich sludge.

In this work, a ratiometric fluorescence sensing platform was established to detect Cu 2+ and D-PA ( d -penicillamine) based on nitrogen-doped Ti 3 C 2 MXene quantum dots ( N -MODs) that was prepared via a simple hydrothermal method and exhibited strong fluorescent and photoluminescence performance as well as excellent stability. Since the oxidation reaction between o -phenylenediamine (OPD) and Cu 2+ induced the formation of 2,3-diaminophenazine (ox-OPD) which not only can emerge an emission peak at 570 nm, but also inhibit the fluorescence intensity of N -MQDs at 450 nm, a ratiometric reverse fluorescence sensor via fluorescence resonance energy transfer (FRET) was designed to sensitively detect Cu 2+ , where N -MQDs acted as energy donor and ox-OPD as energy acceptor. More importantly, another considerably interesting phenomenon was that their catalytic oxidation reaction can be restrained in the presence of D-PA because of the coordination of Cu 2+ with D-PA, further triggering the obvious changes in ratio fluorescent signal and color, thus a ratiometric fluorescent sensor of determining D-PA was proposed also in this work. After optimizing various conditions, the ratiometric sensing platform showed rather low detection limits for Cu 2+ (3.0 nM) and D-PA (0.115 μM), coupled with excellent sensitivity and stability.
