High dielectric single-ion conducting interphase enables fast-charging lithium metal batteries.
The poor stability and slow lithium ion (Li+) transfer kinetics of solid electrolyte interphase (SEI) pose significant challenges to lithium (Li) metal batteries. Although various SEI-related strategies have been developed, the Li+ transport properties and uniform Li deposition still require substantial improvement for fast-charging applications. Herein, we introduce a dielectric, single-ion-conductive artificial SEI (DS-SEI) composed of lithiated Nafion and BaTiO3 (BTO) nanoceramics to address these issues. The lithiated Nafion stabilizes the Li anode with its elastic F-rich components and facilitates fast, single Li+ conduction through its anion-anchored structure. The high-dielectric BTO dynamically homogenizes the electric field (E-field) to promote uniform Li deposition, synergistically enhancing intrinsic single Li+ conductivity and Li+ desolvation/diffusion kinetics, thereby enabling fast charging of the Li anode. Consequently, the DS-SEI protected Li anode can cycle over 6800 h in a Li||Li cell at 10 mA cm-2/5 mAh cm-2, over 400 cycles in a 2.75 mAh cm-2 Li||LiFePO4 cell at 1C, with 83.0 % capacity retention at 6C (16.5 mA cm-2), and maintain stable cycling in a 5.62 mAh cm-2 Li||Li6PS5Cl|| LiNi0.8Co0.1Mn0.1O2 all solid-state cell. Our findings provide insights into the interfacial regulation of Li anode, paving the way for fast-charging Li metal batteries.

Fullerenols as efficient ferroptosis inhibitor by targeting lipid peroxidation for preventing drug-induced acute kidney injury.
Acute kidney injury (AKI) is characterized by rapid and significant deterioration of renal function over a short duration with high mortality. However, the intricate pathophysiological mechanisms underlying AKI have hindered the development of effective therapeutic strategies. Recent research has highlighted the crucial role of ferroptosis in the pathogenesis of AKI and has identified it as a promising therapeutic target. Herein, we investigated the prophylactic efficacy of fullerenol nanoparticles, renowned for their broad-spectrum free radical scavenging capabilities and favorable biocompatibility, in preventing and mitigating ferroptosis-mediated cisplatin-induced AKI. Our findings demonstrate the remarkable potential of fullerenols in mitigating AKI. Specifically, fullerenols exert their protective effects primarily by suppressing renal lipid peroxidation and ferrous iron accumulation, which are two defining hallmarks of ferroptosis. Notably, fullerenols significantly inhibited the upregulation of key enzymes involved in the intracellular lipid peroxidation induced by cisplatin, including acyl-coA synthetase long chain family member 4 (ACSL4), arachidonate lipoxygenase 3 (ALOXE3), and cytochrome P450 oxidoreductase (POR), and enhanced antioxidant systems xc-/Glutathione (GSH)/Glutathione Peroxidase 4 (GPX4). Fullerenols also significantly suppressed the increase in mRNA expression of iron regulation-related genes and prevented the elevation of low-valent iron levels in the kidney tissue of AKI mice. Collectively, our study presents fullerenol as a promising drug candidate for the prevention of AKI in clinical settings, and provides valuable insights into the management of various ferroptosis-associated diseases.

Ultrasmall gold-encapsulated mesoporous platinum to promote photodynamic/catalytic therapy through cascade enzyme-like reactions.
Mesoporous platinum (mPt) nanozyme possessed enzyme-like property of catalase (CAT) and peroxidase (POD), but the insufficient hydrogen peroxide (H2O2) concentration severely restricted its application in photodynamic therapy (PDT) and catalytic therapy. Herein, by depositing ultrasmall gold nanoparticles (AuNPs) and modifying photosensitizer IR808, a multifunctional nanozyme (mPt@Au-IR808) was designed to promote PDT/catalytic therapy through cascade enzyme-like reactions of glucose oxidase (GOx) and CAT/POD. In tumor microenvironment, the CAT-like oxygen (O2) generation improved the PDT efficacy, and the POD-like hydroxyl radical (·OH) generation achieved endogenous catalytic therapy. Using the GOx/CAT-like activities and endogenous H2O2, the yields of singlet oxygen and ·OH were significantly promoted. Furthermore, mPt@Au-IR808 showed higher photothermal conversion efficiency (41.2%) than mPt (36.1%). By combining the photothermal therapy and enhanced PDT/catalytic therapy, the developed mPt@Au-IR808 nanozyme showed excellent anti-tumor efficacy, which will be promising as cascade nanozyme to promote photo/catalytic therapy.

A novel strategy to improve the electrochemical properties of in-situ polymerized 1,3-dioxolane electrolyte in lithium metal batteries.
The application of solid-state electrolytes (SSEs) is anticipated to enhance the safety performance of lithium metal batteries (LMBs). However, the progress of SSEs has been hindered by the unstable electrode-electrolyte interfaces (EEIs). In this study, in-situ polymerization of 1,3-dioxolane (DOL) is employed for the preparation of SSEs, with the addition of tributyl borate (TBB) to establish stable EEIs, particularly under high-voltage conditions. On one hand, the addition of TBB promotes the dissociation of lithium salts and increases the concentration of free Li+, resulting in an increase in room temperature ionic conductivity to 1.13 × 10-4 S cm-1 and an improvement in the Li+ transference number to 0.69 for the prepared poly-DOL electrolytes (PDE-TBB). Benefiting from the enhanced Li+ transport, the Li/PDE-TBB/Li symmetric cell exhibits a cycle life exceeding 1,000 h with a low polarization voltage as low as 12 mV, and the Li/PDE-TBB/LiFePO4 cell demonstrates exceptional cyclic stability over 800 cycles at 1C, with a coulombic efficiency exceeding 99.8 % and a capacity retention of 89.6 %. On the other hand, PDE-TBB exhibits improved stability under high-voltage conditions and the capacity to establish robust boron-rich cathode electrolyte interphase (CEI) on the LiNi0.8Co0.1Mn0.1O2 (NCM811) surface, thereby enhancing the structural stability of cathode materials and ensuring exceptional cycling performance of Li/PDE-TBB/NCM811cell. This work presents a promising strategy for developing novel ether-based SSEs suitable for high-voltage lithium metal batteries.

Coupling multifunctional ZnCoAl-layered double hydroxides on Ti-Fe(2)O(3) photoanode for efficient photoelectrochemical water oxidation.
The efficiency of photoelectrochemical (PEC) water splitting is hindered by the slow kinetics of the oxygen evolution reaction (OER). This study developed a composite photoanode for water oxidation by incorporating ternary LDHs (ZnCoAl-LDH) onto Ti-Fe2O3 as a cocatalyst. The ZnCoAl-LDH/Ti-Fe2O3 photoanode achieved a photocurrent density of 3.51 mA/cm2 at 1.23 V vs. RHE, which is 9.8 times higher than that of bare Ti-Fe2O3. Through a series of characterizations, the synergistic effects among the three metals were revealed. Furthermore, the addition of Zn can induce the formation of more high-valent Co, increasing the conductivity of CoAl-LDH and significantly reducing the surface charge transfer resistance. These advantages significantly enhance the injection efficiency of ZnCoAl-LDH/Ti-Fe2O3 (82 %), thereby accelerating the OER kinetics of Ti-Fe2O3. Our work introduces new approaches for selecting photoelectrochemical cocatalysts and designing high-performance photoanodes for water splitting.
