Lithium (Li) metal anodes (LMAs) that employ three-dimensional lithiophilic frameworks are among the most promising options for constructing high-energy-density rechargeable batteries. Herein, hollow ZnS nanosheets with the coating of N-doped carbon are modified on the surface of carbon cloth (NCHZS@CC) to serve as the host material for Li metal. It is revealed that the high surface area of NCHZS@CC can significantly reduce local current density and mitigate volume change during cycling. More importantly, the lithiated product of ZnS, confined within the carbon cage, facilitates the uniform deposition of Li metal on carbon fibers and promotes the formation of a stable solid electrolyte interphase enriched with Li 2 S, thereby improving long-term performance as the cycling progresses. Consequently, the LMAs based on NCHZS@CC demonstrate an impressive cycle life beyond 560 h with an ultralow overpotential of 38 mV at a current density of 5 mA cm −2 with a capacity of 1 mAh cm −2 in the symmetric cell. In addition, when matched with a high mass loading cathode of LiFePO 4 (11.5 mg cm −2 ), the assembled full cell displays outstanding performance, achieving 900 cycles at a rate of 2C.

Inspired by the exceptional cycling stability of LiFePO 4 , titanium-based polyanionic compounds (e.g., Ti 2 O 1.3 (PO 4 ) 1.6 ) hold significant promise as high-performance anode materials. However, the Ti 3 + oxidation sensitivity, together with the strong covalent P–O bonds in Ti 2 O 1.3 (PO 4 ) 1.6 , hinders phase synthesis and reduce intrinsic electronic conductivity, restricting its Li‑ion storage applications. Herein, carbon-coated mesoporous Ti 2 O 1.3 (PO 4 ) 1.6 nanoplates (C@TOP) are successfully synthesized through a glucose-mediated hydrothermal strategy. This approach enables the precise construction of optimal hierarchical architecture, featuring highly crystalline TOP nanoplates and interconnected mesoporous networks that provide plentiful active sites and beneficial transport channels to boost ion diffusion. In addition, appropriate carbon coating acts as electron highway, its cooperation with rapid Li-ion diffusion markedly improves electrochemical kinetics and reversible lithiation/delithiation. As a result, the optimized C@TOP anode delivers outstanding Li-storage performance, including a prominent capacity of 681.6 mAh g −1 at 200 mA g −1 , excellent cycling stability with 528.3 mAh g −1 after 500 cycles, and exceptional rate capability with 438.0 mAh g −1 at 1000 mA g −1 . Mechanistic analysis unveils a predominantly pseudocapacitive charge-storage mechanism (88 % contribution), enabled by the facilitated ion and electron transport within the well-designed architecture. This work provides useful insights into developing high-performance polyanionic compound-based anodes for next-generation lithium-ion batteries.

Background: The metabolic dysfunction-associated steatotic liver disease (MASLD) represents an escalating global health concern, with effective treatments still lacking. Given its complex pathogenesis, multi-targeted strategies are highly desirable. Methods: This study reports the isolation of four flavone C-glycosides (FCGs) from Dianthus superbus L. and explores their potential in treating MASLD. The bioactivity and underlying mechanisms of FCGs were systematically evaluated by integrating network pharmacology, molecular docking, and zebrafish model validation. Results: Network pharmacology analysis revealed that FCGs may modulate multiple MASLD-related pathways, including lipid metabolism, insulin signaling, inflammation, and apoptosis. Molecular docking further confirmed strong binding affinities between FCGs and key protein targets involved in these pathways. In the zebrafish model of MASLD induced by egg yolk powder, FCGs administration markedly attenuated obesity, hepatic lipid accumulation, and liver tissue damage. Furthermore, FCGs improved lipid metabolism and restored locomotor function. Molecular analyses confirmed that FCGs upregulated PPARγ expression to promote lipid metabolism, restored insulin signaling by enhancing INSR, PI3K, and AKT expression, and suppressed inflammation by downregulating TNF, IL-6 and NF-κB. Additionally, FCGs inhibited hepatocyte apoptosis by elevating the BCL-2/BAX ratio. Conclusions: These findings highlight the multi-pathway regulatory effects of FCGs in MASLD, underscoring its potential as a novel therapeutic candidate for further preclinical development.

The strategic development of high-efficiency electrocatalysts for the oxygen reduction reaction (ORR) remains a pivotal challenge in advancing high-performance zinc-air batteries (ZABs) towards commercial viability. In this work, we developed a template-directed synthesis of Co, N-co-doped polyhedral carbon 3D frameworks (Co-N-C-x) through controlled pyrolysis of Co-ZIF precursors grown on Co-ZnO nanorod self-template. Owing to its unique carbon skeleton architecture and uniform dispersion of Co and N species, the optimized catalyst (Co-N-C-7%) exhibits enhanced ion/electron-transfer kinetics, improved mass transport capabilities. Consequently, the Co-N-C-7% catalyst exhibits superior ORR performance, achieving a half-wave potential (E1/2 = 0.878 V vs. RHE) that is 3 mV higher than commercial 20 wt% Pt/C (E1/2 = 0.875 V vs. RHE), along with exceptional stability. When applied in ZABs, the Co-N-C-7% cathode delivers a higher peak power density (178 mW cm-2) compared to Pt/C-based counterparts (152 mW cm-2). This work provides a simple and reliable control scheme for designing cost-effective, high-performance, and durable ORR electrocatalysts.

The sluggish bidirectional conversion rate between Li 2 S n (2 ≤ n ≤ 4) and Li 2 S, coupled with the uncontrolled deposition of Li 2 S, significantly impedes the realization of high-performance lithium–sulfur batteries (LSBs). In this study, a metal–organic framework was employed as a precursor for the synthesis of a CoO x –CeO 2− y /C (0 < x < 3/2, 0 < y < 1/2) heterojunction via pyrolysis, which was subsequently introduced onto the cathode side of the polypropylene (PP) separator in LSBs. The modification of CoO x –CeO 2− y /C enhances the kinetics of converting of Li 2 S n to Li 2 S during the discharge process. The Tafel slope for the Li 2 S deposition reaction is reduced to 52.1 mV/dec, representing a 56.6% decrease compared to LSBs with bare PP separator. Conversely, during the charging process, the modification lowers the energy barrier for the Li 2 S decomposition reaction, with the activation energy reduced to 6.12 kJ/mol, indicating a 70.3% decrease relative to LSBs with PP separator only. Consequently, more Li 2 S is promoted to undergo decomposition. The CoO x –CeO 2− y /C heterojunction facilitates uniform deposition of Li 2 S, featuring fine particles and a uniform distribution, after brief potentiostatic charging for decomposition, thereby effectively mitigating the deactivation of sulfur species. Thanks to the enhanced bidirectional conversion of lithium polysulfides (LiPS) facilitated by the CoO x –CeO 2− y /C modification layer, the (−)Li|CoO x –CeO 2− y /C@PP|S(+) coin cell maintains a Coulombic efficiency of 90.4% after 500 cycles at a current density of 1 C, exhibiting a low capacity-decay rate of only 0.081% per cycle, thereby demonstrating excellent long-cycle stability.

Although high-capacity silicon/carbon (Si/C) composites are widely recognized as the most promising alternative to commercial graphite anodes for next-generation high-energy lithium–ion batteries (LIBs), their practical implementation faces significant challenges due to structural and interfacial instability caused by the substantial volume expansion of Si during charge–discharge cycles. Developing cost-effective binders with superior bonding strength and excellent interfacial compatibility for multicomponent Si/C electrodes is crucial to overcoming these limitations. Herein, we have successfully synthesized a linear copolymer binder (HAMN) incorporating four distinct functional units through a facile one-pot aqueous radical polymerization method. This innovative binder demonstrates multiple advantages, including cost efficiency, exceptional water solubility, superior slurry rheology, remarkable mechanical flexibility, and strong interfacial affinity for Si/C composites. The HAMN-based Si/C electrode exhibits outstanding electrochemical performance, maintaining 91.24% capacity retention after 600 cycles at 0.5C in a half-cell configuration. More importantly, in practical 18,650 cylindrical full-cell tests, the battery demonstrates impressive cycling stability with capacity retention rates of 86.2% after 400 cycles at 0.5C and 78.84% after 700 cycles at 1C. These compelling results underscore the tremendous potential of the HAMN binder in enabling the practical application of high-energy Si/C composite anodes for advanced LIBs.

Oxidation of fatty alcohols to fatty acids is still challenging due to the sluggish activation of the C–H bond over Au supported on reducible oxides with a coordination-saturated structure. Herein, we constructed an efficient interfacial Auδ−–OV–Ti structure by tuning the crystal forms of TiO2. Compared with TiO2-rutile exposed by (110) and (111) crystal facets, TiO2-anatase can exploit the defect (101) crystal facet to obtain rich oxygen vacancies (OV), inducing electron migration from TiO2-anatase support to Au species to form electron-rich Auδ− species. Specifically, the synergistic catalytic effect between the OV–Ti and Auδ− species greatly enhances the adsorption of alcohol and thereby overcomes sluggish activation of the C–H bond caused by the electron pushing effect triggered by long carbon chains. Consequently, the Au/TiO2-anatase catalyst shows excellent isooctyl alcohol conversion (69.5%) and isocaprylic acid selectivity (67.9%) under base-free conditions. The catalytic system is further extended to the oxidation of other fatty alcohols to fatty acids with excellent catalytic performance.

Because of their great capacity to store lithium, cobalt-based phosphides are utilized as anode materials for lithium-ion batteries (LIBs). However, in practice, they are prone to capacity fading and volume expansion, which restrict their long-term use. Herein, a simple method was proposed to prepare CoP nanoparticles encapsulated in a Co-MOF-71 derived carbon layer (CoP/C). The carbon in the composites greatly improved the cycling stability and rate capability of CoP/C when compared with pure CoP. CoP/C exhibits a high initial discharge capacity of 823 mA h g−1, a cycling durability of 338 mA h g−1 over 100 cycles, a good initial coulombic efficiency of ca. 76%, and an excellent rate capability (1 A g−1: 318 mA h g−1 and 2 A g−1: 284 mA h g−1).

The oxygen reduction reaction (ORR) plays a crucial role in key processes of fuel cells and zinc-air batteries. To enable commercialization, reducing the platinum (Pt) content and increasing the specific activity per unit mass is essential. A promising approach involves synthesizing of Fe-N-C precursors via the polyaniline (PANI) pathway, which ensures a uniform distribution of Fe-N-C species and facilitates the subsequent adsorption of platinum ions. This leads to the formation of Pt-Fe bimetallic alloys. The synergistic interaction between Pt and Fe-N-C sites promotes the homogeneous dispersion of Pt and the formation of smaller particle sizes, which in turn enhances intrinsic activity and stability of the catalyst. Notably, the Pt/Fe-N-C catalyst, featuring an ultra-low Pt loading of just 1.79 wt%, exhibits a remarkable doubling of mass activity compared to conventional catalysts. Moreover, zinc-air batteries using this catalyst achieve an impressive peak power density of 200 mW/cm 2 .

Atopic dermatitis (AD) is a multifactorial chronic inflammatory skin disease characterized by skin barrier dysfunction, eczematous lesions, pruritus, and abnormal immune responses. In this study, we assessed the therapeutic effect of topical applied conjugated linoleic acid (CLA) on a murine AD model that was developed by repetitive applications of 2, 4-dinitrofluorobenzene (DNFB). 2% or 5% CLA could markedly ameliorate AD-like skin lesions, scratching behaviour and skin inflammation as evidenced by the reduced inflammatory blood cells, IgE and Th2-related cytokine levels, and the infiltration of mast cells and inflammatory cells to the dermal tissues. Moreover, topical application with CLA modulated skin barrier repair including maintaining a balanced skin pH and increasing skin hydration, partially mediated by upregulating skin barrier-related protein, filaggrin (FLG). In addition, topical CLA significantly dose-dependently inhibited pro-inflammatory cytokines including interleukin (IL)-6, IL-1β, tumour necrosis factor (TNF)-α and pro-inflammatory enzyme expressions of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) in inflamed mice skin. Its anti-inflammatory effect was associated with the inhibition of DNFB-stimulated IκBα and NF-κB p65 phosphorylation in mouse skin. Taken together, our results suggest that locally applied CLA exerts potentially protective effects against AD lesional skin at least in part, due to regulation of skin barrier function and inflammatory response.

Background Acute liver injury (ALI) is an essential component of sepsis associated with poor outcomes. Octanoic acid (OA), a medium-chain fatty acid, has a protective effect on sepsis-induced organ damage, and autophagy is an adaptive response to sepsis. However, the underlying mechanism by which OA prevents ALI remains unknown. Therefore, we investigated whether OA-rich enteral nutrition (EN) prevented lipopolysaccharide (LPS)-induced ALI through the c-Jun N-terminal kinase (JNK)-dependent autophagy. Methods Firstly, Sprague Dawley rats were randomly divided into four groups (sham, LPS, LPS + EN, and LPS + EN + OA) to detect the effect of OA-rich EN on LPS-induced ALI. Then, rats were randomly divided into five groups (sham, LPS, LPS + EN + OA, LPS + EN + OA + anisomycin (AN), and LPS + SP600125) to explore the mechanism by which OA-rich EN prevented ALI. EN and OA-rich EN were conducted through gastric tubes for 3 days. The liver protective effects were measured by liver histopathological changes, enzymes, inflammatory cytokines of serum and liver, the levels of autophagy, and JNK activity. Results OA-rich EN inhibited JNK activity, up-regulated autophagy and prevented LPS-induced ALI. Inhibition of JNK activity conferred by SP promoted autophagy and prevented LPS-induced ALI. Moreover, the protective effect of autophagy and inhibition of JNK activity conferred by OA-rich EN on ALI was counteracted by AN. Conclusion OA-rich EN prevented LPS-induced ALI through JNK-dependent autophagy. This result suggested that OA-rich EN may be a therapeutic potential for ALI in patients with sepsis.
