The nano-based therapeutics to induce cellular oxidative damage is considered promising in cancer treatment. Photodynamic therapy (PDT) is a primary antitumor oxidative damage treatment method. However, the hypoxic environment of tumor tissues and the short lifetime of singlet oxygen significantly hampers PDT efficacy. Fortunately, nitric oxide (NO), as a form of gas therapy, can generate more toxic oxidative peroxynitrite ions (ONOO−) with hydrogen peroxide (H2O2), which significantly enhance the efficacy of PDT. In this context, we fabricated a thermally controlled reactive oxygen nanobombs CaO2@LA-ICG@TD (CAI@TD), which can release many reactive oxygen species (ROS) to enhance the synergistic anticancer efficiency under a. The cellular studies revealed that CAI@TD could produce oxygen and H2O2 to heighten the efficacy of PDT and NO and induce necrotic-apoptosis of MDA-MB-231 cells by mitochondria damage, lipid peroxidation, and DNA fragments. Moreover, CAI@TD with 808 nm laser irradiation achieved a significant inhibition on the xenograft tumor growth. This work provides an efficient strategy to produce a high amount of ROS for synergistic anticancer therapy, offering a ray of hope in the fight against cancer.

Electrocatalytic materials in the electrochemical reduction of carbon dioxide (CO2ER) provide an effective strategy to mitigate CO2 emissions, enable carbon recycling, and synthesize high-value multi-carbon (C2+) chemicals, thereby supporting long-term renewable energy storage. Recent advances highlight that yolk-shell nanostructures, which regulate adsorbed CO intermediates (*CO), offer a promising tandem catalysis pathway to convert CO2 to C2+ products. In this study, we designed Pd@Cu2O/Cu2S yolk-shell catalysts, which demonstrated a Faradaic efficiency (FE) of 81.7 % for C2 products at −0.8 V vs. RHE, with an FE of 44.7 % for ethanol (C2H5OH). This performance is attributed to the synergistic interplay between Pd, which efficiently generates *CO intermediates, and Cu surfaces, which facilitate rapid CC coupling to form C2 products. In situ attenuated total reflection surface-enhanced infrared absorption spectroscopy (ATR-SEIRAS), X-ray absorption spectroscopy (XAS), and density functional theory (DFT) calculations further reveal that Pd and S modulate the reaction energy barrier of the *OCCOH intermediate, steering selectivity toward C2 products and enabling partial C1-to-C2 conversion. This research offers a strategy for synthesizing Cu-based tandem catalysts and improving C2 product selectivity of CO2ER.

Inducing adipose browning to increase energy expenditure has recently emerged as a promising approach for antiobesity treatment. However, its therapeutic efficacy is often limited by poor adipose-targeted drug delivery and suboptimal browning efficiency. To address these challenges, an adipose-targeting aptamer (Apt8) and browning agent resveratrol (Res) were used to construct an Apt-modified and Res-loaded degradable mesoporous silica–coated Au nanorods nanocarriers (NC), termed Res@NC@Apt8, achieving adipose-targeted hyperthermia–pharmacotherapy. Upon internalization by adipocytes, laser irradiation induces mild local hyperthermia (LHT) via Res@NC@Apt8, triggering calcium ion (Ca2+) influx. Simultaneously, the interaction of the nanohybrid with local glutathione (GSH) releases Res. The dual mechanisms activate the adenosine 5′-monophosphate-activated protein kinase (AMPK) pathway, reduce the lipid droplet content, enhance mitochondrial biogenesis, and accelerate metabolism, thereby synergistically promoting adipose browning. Intravenous Res@NC@Apt8 administration in obese mice significantly drives adipose reduction and further achieves excellent antiobesity therapeutic efficacy. This synergistic treatment achieves a superior weight reduction of 17.2% compared with 6.9% and 10.6% achieved using LHT and pharmacotherapy alone, respectively. This study introduces a novel strategy for achieving activatable LHT and drug release for synergetic obesity treatment.

The electrochemical oxidation of cyclohexanone to produce adipic acid (AA), coupled with hydrogen (H2) production, represents a promising strategy. However, the development of low-cost and high-performance electrodes remains a significant challenge. Herein, we present Ni@Cu dual-metal heterogeneous material as a proof of concept, demonstrating its potential for efficient co-electrosynthesis of adipic acid and H2. The Ni@Cu material, featuring abundant heterogeneous interfaces, is grown on copper foam (CF) through a straightforward electrochemical reconstitution strategy. This approach enhances the exposure of catalytic active sites, improves interfacial charge transfer, and accelerates reaction kinetics during electrolysis. As a result, the Ni@Cu/CF electrode achieves low potentials of −172 mV vs. RHE and 1.55 V vs. RHE at 100 mA cm−2 for the hydrogen evolution reaction (HER) and cyclohexanone oxidation reaction (COR), respectively. The assembled HER||COR electrolyzer delivers a high adipic acid yield (1.15 mmol h−1 at 250 mA cm−2) and a maximum Faradaic efficiency (FE) of 88 % at 100 mA cm−2. It also achieves a high FE for H2 (over 96 % at 250 mA cm−2) and demonstrates excellent co-electrolysis stability for over 100 h. In-situ spectroscopy confirms that the formation of heterogeneous Ni@Cu facilitates the generation of active species and accelerates their kinetic transformation into adipic acid.

Tailoring the hole transport layer (HTL) between BiVO4 (BVO) and oxygen evolution co-catalysts (OECs) interfaces is a leading strategy to improve the performance of photoelectrochemical (PEC) water splitting. Nevertheless, the limited driving force at the BVO/OECs interfaces severely hinders the transport of charge carriers. In this study, we designed a specialized defective transition metal oxide (Vo-MnOx) as the HTL. The integrated photoanode (BVO/Vo-MnOx/CoFe(OH)x) exhibits an impressive photocurrent density at 1.23 V vs. RHE, along with an outstanding ηsurface value of 91.91 %. These remarkable outcomes are due to the fact that Vo-MnOx as HTL effectively enhances the interface driving force and charge migration ability, which is largely attributed to the ability of Vo to accumulate electrons and accelerate rapid cyclic transitions of multivalent Mn. Satisfactorily, microscopic perspective studies reveal that the distinctive Vo-MnOx can efficiently promote photogenerated charge transfer, as shown in dynamic carrier analysis using scanning photoelectrochemical microscope (SPECM). Additionally, the oxygen evolution reaction model suggests that a defective HTL can improve surface catalytic kinetics. This work provides valuable insights into the role of Vo in regulating the valence state changes in PEC water splitting.

The commercial development of lithium-sulfur batteries (LSBs) has been significantly hindered by the “shuttle effect” and the slow redox kinetics of lithium polysulfides (LiPSs). To solve these problems, researchers have designed a variety of catalysts for the conversion of LiPSs. However, the multi-step lithium polysulfide conversion process is difficult to be effectively solved by a single-function catalyst. In this study, a novel hollow nanocage composite CoS2/NiS2 with heterogeneous interfaces (CoS2-NiS2) is designed to dual modify the cathode host and separator. These CoS2-NiS2 heterojunctions can enhance the trapping ability of LiPSs and improve the wettability, thereby mitigating the shuttling of LiPSs. Besides, the CoS2-NiS2 heterogeneous interface exhibits a strong internal electric field, which effectively enhances the electronic conductivity of the composites. Moreover, this strong electric field at the CoS2-NiS2 heterojunctions offers excellent catalytic ability for sulfur reduction so that can remarkably promote the conversion of LiPSs. Due to these multi-functional characteristics, the CoS2-NiS2 nano-composite demonstrates excellent adsorption and catalytic properties. The as-obtained battery achieves a high initial specific capacity of 1037.4 mAh g−1 and a low decay rate of 0.047 % per-cycle. This study offers a comprehensive understanding of interfacial catalytic mechanisms and their impact on sulfur reaction kinetics, particularly for binary metallic-compounds heterojunctions.

Aqueous zinc ion batteries (ZIBs) are expected to be the next generation of energy storage devices. However, the unwanted dendrites growth on zinc anodes, hydrogen evolution and other side reactions hinder the practical application of ZIBs. Here, we designed a novel inorganic-metal hybrid coating with an optimised electric double layer structure at the zinc anode/electrolyte interface. The hybrid coating effectively promotes ionic desolvation, reduces the nucleation overpotential, and suppresses the 2D diffusion process. Furthermore, the coating has good stability and inhibits the dendrites growth, hydrogen precipitation corrosion, and by-products generation. Consequently, the hybrid coating-modified Zn anode exhibited excellent electrochemical performance. Among them, the symmetric cell was able to cycle for 1480 h at 1 mA cm−2, 1 mAh cm−2 with an overpotential of ∼34 mV. The symmetric cell achieved a cycle life of ∼1000 h even at a high current of 3 mA cm−2. The cycling performance and multiplication rate performance in full cells were also demonstrated. This work shows the effectiveness and feasibility of hybrid coating to modulate zinc anode/electrolyte interface.

The triggering of fast hydrogen spillover through regulating the charge rearrangement of the metal-support serves as a crucial mechanism for decoupling the activity of HER catalysts from the adsorption properties, which not only contributes to enhancing the performance of the catalysts but also facilitates the production of green hydrogen. Herein, we tailor the electronic interaction between two-dimensional (2D) nitrogen-doped MoC (N-MoC) nanosheets and an ultra-low content of Pt nanoclusters (1 wt%) to trigger reverse hydrogen spillover and modulate the electronic structure of Pt, thus achieving efficient and stable HER. Compared to Pt/C (0.229 A mgPt−1), Pt/N-MoC demonstrates a mass activity of 12.945 A mgPt−1, representing an enhancement of nearly 57.5 times. Notably, the excellent electrocatalytic performance was verified in the proton exchange membrane water electrolyzer configuration. Combining experimental and theoretical analysis, an ultra-low load of Pt nanocluster (1 wt%) integrated with N-MoC nanosheets can induce a charge transfer from N-MoC to Pt, thus modulating the d-band center of Pt to improve the hydrogen adsorption properties and achieving fast hydrogen desorption (ΔG = 0.019 eV); furthermore, a small difference in work function between Pt nanoclusters and the N-MoC were achieved to dilute charge accumulation between the metal-support interface, thus reducing the energy barrier of hydrogen spillover.

The inherent issues of aqueous Zn-ion batteries, including side reactions and dendrite growth, can be effectively addressed through designing solvation structures enriched with anions to facilitate the formation of an anion-derived solid electrolyte interphase (SEI) layer. Here, the weakly solvating effect is utilized to modulate Zn2+ solvation structure for constructing an anion-derived SEI layer. Trifluoroacetamide (TFACE), with a specific weak solvating ability, serves as an ideal ligand for preparing hydrated eutectic electrolytes (HEEs) combining the anion-containing solvation structures and high ionic conductivity. The results demonstrate that coordinated anions preferentially decompose and generate an inorganic/organic hybrid SEI layer on the Zn anode, which efficiently suppresses both side reactions and dendritic growth. Such an electrolyte enables assembled Zn//polyaniline (PANI) full cells to process an impressive capacity retention, maintaining 80 % after 3000 cycles at 0.5 A g−1. This work provides a fundamental insight into building the anion-derived SEI by the weakly solvating effect and gives a viable route for designing advanced aqueous electrolytes.

Acute liver injury (ALI) is characterized by rapid and severe hepatocellular damage, leading to ferroptosis and an exacerbated inflammatory response. Mesenchymal stem cell-derived exosomes (MSC-exo) have emerged as a promising therapeutic strategy for ALI due to their ability to deliver antioxidants and stabilize solute carrier family 7 members 11 (SLC7A11)/glutathione peroxidase 4 (GPX4) system. In this study, we developed a novel engineered exosome, MSC-exo/MnO2@DEX, by encapsulating the anti-inflammatory drug dexamethasone (DEX) within MSC-exo and modifying its surface with manganese dioxide (MnO2) via a bionano-mineralization approach. MnO2 exhibits multi-enzymatic activity, enabling efficient scavenging of reactive oxygen species (ROS), such as hydrogen peroxide and superoxide anions. When combined with MSC-exo, MnO2 not only reduces ROS levels and generates oxygen but also stabilizes the SLC7A11/GPX4 axis, thereby protecting hepatocytes from ferroptosis. Concurrently, DEX suppresses the nuclear factor-κB (NF-κB) signaling pathway, inhibits macrophage M1 polarization, and alleviates hepatic inflammation. The oxygen produced by MnO2 catalysis further mitigates hypoxia, decreases lactic acid accumulation, and downregulates histone lactylation, synergizing with DEX to enhance NF-κB pathway inhibition and amplify anti-inflammatory effects. Transcriptomic analyses revealed that MSC-exo/MnO2@DEX significantly enhances antioxidant capacity, metabolic processes, and immune function, while improving liver function and suppressing ferroptosis, lactylation and inflammatory responses. Collectively, these findings demonstrate the therapeutic potential of MSC-exo/MnO2@DEX as an effective treatment for ALI.
