Chlorine-rich lithium argyrodites with ultrahigh ionic conductivity show great potential as solid electrolytes in all-solid-state batteries, while the poor moisture and lithium metal compatibility limit their applications. Here, by tailoring Sb and O dual dopant , Li 5.5 P 0.96 Sb 0.04 S 4.40 O 0.10 Cl 1.5 electrolyte delivers a high Li-ion conductivity up to 7.20 mS cm −1 , excellent air/moisture and lithium metal endurance. The improved air stability is due to the strong Sb–S and P–O bonds in the co-doped electrolyte, inhibiting the reaction with water. While the enhanced lithium metal stability is attributed to the formation of the Li–Sb alloy layer , impeding the growth of lithium dendrites during cycling. The lithium symmetric cell using Li 5.5 P 0.96 Sb 0.04 S 4.40 O 0.10 Cl 1.5 exhibits high critical current density (1.5 mA cm −2 ) and ultralong cyclability (750 h, 0.1 mA cm −2 ). The all-solid-state lithium metal battery using LiNi 0.6 Mn 0.2 Co 0.2 O 2 cathode affords a high initial discharge capacity of 144.2 mAh g −1 at 0.1C. Moreover, the assembled battery shows a discharge capacity of 116.2 mAh g −1 at 0.5C and a capacity retention rate of 83.2% after 200 cycles. This work provides the guideline to design sulfide solid electrolytes that enable all-solid-state lithium metal batteries with high energy density and long cyclability.

Despite advances in membrane technology, the separation of complex oily wastewater using membrane filtration remains a daunting challenge for the industry. Recent approaches including membrane modification with two-dimensional (2D) nanosheets, showed susceptibility to swelling, fouling, and instability during operation. As a game-changer approach, a polyacrylonitrile (PAN) UF membrane modified with 3D nanostructured composite of MXene and O-MWCNT was introduced for the first time to treat complex oily wastewater. The composite membrane showed high separation performance of soluble dye-oil-water emulsion while maintaining high water permeability. Moreover, during the operational period, the composite membrane exhibits excellent antifouling and anti-swelling properties due to the synergetic effects conferred by the 3D nanostructures. Furthermore, the composite membrane possesses remarkable chemical stability evidenced by its high corrosion resistance when exposed to a strong acid (3 M HCl) and oxidant (NaOCl) solution for a long-time period. Overall, the operational stability was maintained in terms of flux and high rejection of oil and dye over a 45 h long-term operation. Consequently, this work provides an innovative, stable, and highly facile process for fabricating scalable UF composite membrane for the treatment of complex oily wastewater in a harsh chemical environment.

Relatively small amounts of In-doped Mo(O,S) 2 (IMS) catalysts (10%, 20%, and 30%) were deposited on cellulose nanofiber (CNF) by cross-linking them with functional groups of siloxane and epoxy to form CNF-IMS hybrid composites. The as-prepared hybrid composites were characterized and tested their performances toward the photo degradations of cationic (MB and RhB) and anionic (MO) dyes. As indium was doped into Mo(O,S) 2 lattice to form solid-solution, the charge transfer and photocarrier separation during the catalytic reaction were simultaneously enhanced as probed with electrochemical impedance spectroscopy and photoluminescence measurements, respectively. To ensure the catalyst on CNF was well deposited and recyclable, the hybrid composite was evaluated with a reusability experiment to show the stability performance in degrading organic dyes. It was found the environmentally friendly CNF-IMS hybrid composite was relatively stable during the reusability experiment, indicating no catalyst powder was leached out during the photocatalytic reaction. The photoreaction mechanism was convinced by radical-scavenging experiments to show that hydroxyl and superoxide played essential roles for the organic dye degradations in visible-light illuminated conditions. The cross-linked organic/inorganic hybrid catalyst showed a prospective visible light active material not only to solve the environmental issue due to the leaching of nanoparticles but also to lower the post-treatment/recycling cost of photocatalyst in industrial application.

Previous studies have demonstrated the endocrine disruption of o,p′-DDT. In this study, we used a 1H NMR based metabolomics approach to investigate the estrogenic effects of o,p′-DDT (300 mg/kg) on the uterus and brain after 3 days of oral gavage administration, and ethynylestradiol (EE, 100 μg/kg) was used as a positive control. A supervised statistical analysis (PLS-DA) indicated that o,p′-DDT exerted both estrogenic receptor-(ER)-dependent and independent effects on the uterus but mainly ER-independent effects on the brain at metabolome levels, which was verified by coexposing with the antiestrogenic ICI 182,780. Four changed metabolites—glycine, choline, fumarate, and phenylalanine—were identified as ER-independent alterations in the uterus, while more metabolites, including γ-aminobutyrate, N-acetyl aspartate, and some amino acids, were disturbed based on the ER-independent mechanism in the brain. Together with biological end points, metabolomics is a promising approach to study potential estrogenic chemicals.

A strategy combining O- and N-containing directing groups has been developed for the synthesis of 2,2′-biaryl via Pd-mediated C–H bond activation and oxidative coupling. This new transformation may proceed through a mechanism involving Pd(II) and Pd(IV) intermediates. We found the use of PTSA and HFIP to be critical for the reaction and suggest that these reagents could serve as efficient ligands for this C–C bond formation. This methodology provides broad functional group tolerance, excellent reactivity, and high yields.

Polycystic ovary syndrome (PCOS) is a common endocrine disorder that poses a great threat to women's health. MiR-1224-5p is downregulated in the follicular fluid of patients with PCOS, but its role remains largely unknown. In this study, mice were treated with dehydroepiandrosterone (DHEA) to establish an in vivo model of PCOS. We found that enhanced activation of NLRP3 inflammasome was accompanied by downregulation of miR-1224-5p in ovarian tissue of PCOS mice. The effect of miR-1224-5p was further explored in TNF-α-treated human granulosa-like tumor (KGN) cells. Upregulation of miR-1224-5p suppressed TNF-α-induced secretion of DHEA and testosterone. MiR-1224-5p attenuated TNF-α-induced inflammation by inhibiting NLRP3 inflammasome activation, IL-1β synthesis, and nuclear factor kappa B (NF-κB) p65 nuclear translocation. Notably, miR-1224-5p decreased the expression of Forkhead box O 1 (FOXO1) and its downstream gene thioredoxin interaction protein (TXNIP). Luciferase reporter assay confirmed FOXO1 as a target of miR-1224-5p. Upregulation of FOXO1 abolished miR-1224-5p-induced activation of NLRP3 inflammasome, demonstrating that miR-1224-5p might inhibit NLRP3 inflammasome activation through regulating FOXO1. This study provided novel insights into the pathogenesis of PCOS and suggested that miR-1224-5p might be a promising target for treating PCOS.

Depolymerizing lignin to produce high-value chemicals has garnered increasing attention. Given the complex structure of real lignin, the cracking efficiency ofβ-O-4 linkages and the selectivity of depolymerization products are significantly lower than those of lignin model compounds. Meanwhile, the relationship between the structure of lignin and theβ-O-4 linkage cracking was ignored. In this work, to well address the issue, three real lignins (corncob lignin (CL), pinus massoniana lignin (PML), and eucalyptus lignin (EL)) were employed to discuss the impacts of special ether bonds in lignin on theβ-O-4 linkage cracking in the no-additional-hydrogen catalytic system mediated by a CoNi2@BTC catalyst. The lignin depolymerization results showed that the ether bonding structure in the lignin significantly impacted the cracking ofβ-O-4 linkages and selectivity of the final products, resulting in a great difference among their intermediates. Notably, the methoxy groups in the real lignin greatly inhibited the further hydrogenation of phenolic compounds, resulting in the accumulation of abundant methoxy-substituted phenolic compounds and a low yield of cycloalkanes (12.37% to 14.06%). To deeply discuss theβ-O-4 linkage cracking in the lignin depolymerization, degradation experiments with coexisting ether bond compounds were performed, and the activation energy was employed to quantitatively evaluate the impacts of other ether bonds on theβ-O-4 linkage cracking. The results revealed that multiple ether bonds (α-O-4, 4-O-5, and methoxy group) significantly increased the activation energy (from 236% to 373%) ofβ-O-4 linkages, resulting in the evident decline in theβ-O-4 model compound. In addition, the degradation of the methoxy-substitutedβ-O-4 model compound (GG) demonstrated that the methoxy-substituted aromatic ring products were resistant to further hydrogenation, resulting in the accumulation of methoxy-substituted aromatic ring products in the depolymerization of real lignin. All the findings will provide a novel perspective for the targeted high-value utilization of real lignin in chemical production.

3,5-O-Dicaffeoylquinic acid (3,5-DCQA) from edible Gongju chrysanthemum has shown protective effects against alcoholic hepatocyte injury in our previous study. However, the specific effects and mechanisms of 3,5-DCQA in a mouse model of liver injury remain underexplored. This study aimed to examine the efficacy and primary mechanism of 3,5-DCQA from Gongju chrysanthemum in ameliorating acute alcoholic liver injury in mice. The results indicated that 3,5-DCQA effectively attenuated inflammation and apoptosis by regulating the content of key factors (e.g. MyD88, NF-κB) in the TLR-4/NF-κB pathway, contributing to its protective role against alcohol-induced liver injury. 3,5-DCQA also inhibited inflammation and apoptosis by recovering the key metabolites (e.g. phosphatidylserine) and related genes (e.g. Lpgat1) of glycerophospholipid metabolism. These results were further verified by transcriptomic and metabolomic analyses, showing that 3,5-DCQA exerts protective effects against alcohol-induced liver injury by modulating glycerophospholipid metabolism and suppressing oxidative stress, inflammation, and apoptosis through the TLR-4/NF-κB pathway. The current findings highlight the hepatoprotectivity of 3,5-DCQA and may facilitate the application of Gongju chrysanthemum in liver-protective functional foods.

Green tea occupies a prominent position in the Chinese tea market. Although drying the tea constitutes a critical processing step, its mechanistic impact on aroma quality remains unclear. This study aimed to investigate the effects of three drying methods—roasted drying (RD), pan drying (PD), and sun drying (SD), namely, on green tea aroma formation. Sensory molecular science and targeted metabolomic analyses indicated that PD resulted in distinct chestnut- and bean-like aromas, while SD resulted in fatty and green aromas. ( E )-2-heptenal, ( E )-2-octenal, and nonanal, characteristic of SD green tea, were found to be the key sources of fatty aroma. These compounds are typically produced by the degradation of unsaturated fatty acids such as linoleic, oleic, and palmitic acids. Conversely, 2,5-dimethylpyrazine and 3,5-diethyl-2-methylpyrazine, generated through the Maillard reaction (MR), were identified as primary contributors to the chestnut- and bean-like aromas resulting from PD. Precursor analysis (soluble sugars, free amino acids, fatty acids, and MR intermediates) substantiated these findings. This study systematically elucidates drying-driven aroma modulation mechanisms, providing a theoretical foundation for optimizing the aroma quality of green tea.

Aldol condensation of biomass-derives coupled with hydrogenation is a promising route for the production of renewable aviation fuel. In this study, a bifunctional catalyst was prepared to integrate the aldol condensation of cyclopentanone and hydroprocessing for aviation fuel in one pot. Due to its strong mild-basic sites, Mg–Al–O performed the best with the total yield of dimer and trimer of 80.4%. Nickel was screened out to be favorable for hydrogenation. Considering the unsatisfactory porous structure of Ni/Mg–Al–O, the bifunctional catalyst was prepared with activated carbon (AC) as carrier. With Ni loading of 20 wt%, the maximum yield of targeted alkanes reached 81.1% over Ni/Mg–Al–O/AC. The calcination and reduction temperature in the preparation process were both optimized at 550 °C. In the reusability test, the yield of targeted alkanes reduced to 31.6% in the 5th run. To attenuate the hydration effect, n-pentane was introduced as solvent, and the bifunctional Ni/Mg–Al–O/AC performed stably in 5 runs. By the design of bifunctional catalyst based on the theoretical basis to realize the integration of C–C coupling and hydrogenation in one pot, it will promote the development of aviation fuel from biomass in a more sustainable and green way.

PCPDI exhibits high thermal stability and strong fluorescence. The PCPDI shows ultrahigh sensitivity to tracing o-nitrophenol in chloroform with KSV constant of 1.74 × 105 L mol−1 and detection limit (LOD) of 1.72 × 10−11 mol L−1.

The activation of the lattice oxygen oxidation mechanism is vital for enhancing oxygen evolution reaction (OER) performance as it enables direct O–O bond formation, avoiding the *OOH formation. Compared with the conventional adsorbate evolution mechanism (AEM), the lattice oxygen-mediated mechanism (LOM) can break the theoretical limit of conventional adsorbate-based scaling relations and enhance the oxygen evolution reaction kinetics. Thus, there is an urgent need for an efficient strategy for designing OER electrocatalysts based on LOM. The O p band center is employed as descriptor in conjunction with machine learning to facilitate the activation of lattice oxygen. The descriptor can accelerate the catalyst design process as it circumvents the need for complex intermediate calculations. According to predictions, the Fe-Co 3 O 4 catalyst exhibits OER performance comparable to that of noble metal catalysts. The Fe-Co 3 O 4 catalyst achieves a low overpotential of 258 mV at 20 mA cm -2 in 0.5 M H 2 SO 4 , attributed to the shift in catalytic mechanism from AEM to LOM.The incorporation of Fe effectively induces an upshift in the O p band center and weakens the Co–O bond, thereby promoting direct O–O coupling for O 2 generation and consequently reducing the OER overpotential. Our study introduces a method to activate the lattice oxygen of metal oxide electrocatalysts, holding substantial promise for enhancing large-scale hydrogen production.
