Lithium-sulfur batteries(LSBs)with high energy densities have been demonstrated the potential for energy-intensive demand applications.However,their commercial applicability is hampered by hysteretic electrode reaction kinetics and the shuttle effect of lithium polysulfides(LiPSs).In this work,an interlayer consisting of high-entropy metal oxide(Cu_(0.7)Fe_(0.6)Mn_(0.4)Ni_(0.6)Sn_(0.5))O_(4) grown on carbon nanofibers(HEO/CNFs)is designed for LSBs.The CNFs with highly porous networks provide transport pathways for Li^(+) and e^(-),as well as a physical sieve effect to limit LiPSs crossover.In particular,the grapevine-like HEO nanoparticles generate metal-sulfur bonds with LiPSs,efficiently anchoring active materials.The unique structure and function of the interlayer enable the LSBs with superior electrochemical performance,i.e.,the high specific capacity of 1381 mAh g^(-1) at 0.1 C and 561 mAh g^(-1) at 6 C.This work presents a facile strategy for exploiting high-performance LSBs.

Li-CO_(2) batteries provide an attractive and potential strategy for CO_(2) utilization as well as energy conversion and storage with high specific energy densities.However,the poor reversibility caused by the decomposition obstacles of Li_(2)CO_(3) and C products is still a challenge for Li-CO_(2) batteries,which seriously influences its electrochemical performances.Herein,a free-standing MnOOH arrays cathode has been prepared and employed in Li-CO_(2) battery,which realizes a great improvement of electrochemical performances by adjusting the discharge products distribution.Experiments coupled with theoretical calculations verifies that the formation of Li-containing carbonaceous species(LiCO_(2),LiCO and Li_(2) CO_(3))bonded with MnOOH through Li ion regulates the nucleation behavior of Li_(2)CO_(3) and C,making them grown on MnOOH uniformly.The fine Li_(2) CO_(3) grains(with a size about 5 nm)embedded into carbon matrix greatly enlarges the contact interface between them,facilitating the transmission of electrons through the discharge products and finally improves CO_(2) evolution activity.This ingenious design strategy of regulating discharge products distribution to improve electrochemical performances provides a promising way to develop advanced Li-CO_(2) batteries.

Lithium metal batteries(LMBs)have received increasing attention due to the high energy density.However,the practical application of LMBs is limited due to the incompatibility of ester electrolytes.Transition metal(TM)nitrates have been reported as effective additives in ester electrolyte to improve the stability of lithium anode.Unfortunately,the nitrates are restricted to use due to their poor solubility.We find that the nitrates containing crystal water have high solubility in ester electrolytes.Considering that most TM nitrates contain crystal water and the crystal water can be used as a perfect solubilizer of nitrates,thus,the method is of universality and facile without introducing any solubilizing agent.Herein,In(NO_(3))_(3.6)H_(2)O is chosen as one typical case with increased solubility up to 0.2 M compared with In(NO_(3))_(3)which hardly dissolves in ester electrolyte.The additive promotes the rapid and stable formation of the solid electrolyte interface(SEI),which effectively inhibits the lithium dendrites formation.Moreover,the induced cathode electrolyte interface(CEI)maintains the structural stability of Li Ni_(0.8)Co_(0.1)Mn_(0.1)O_(2)(NCM811).As a result,the electrochemical performance of Li|NCM811 cell is obviously improved.Our study provides a new idea for dissolving nitrates in ester electrolytes and discloses the synergistic function of TM-ions.

Luminescence is one of the most important properties for metal nanoclusters;however,clearly revealing its origin remains challenging.The different luminescence properties of the two prototypical 8e nanoclusters Au_(11)and Au_(13)remain elusive—Au_(11)is always nonluminescent,whereas Au_(13)is luminescent.In this work,by using a designed unique aromatic ligand(quinoline-2-thiol),we obtained new atomically precise phosphine-thiolate-protected neutral Au_(11)-SH and cationic Au_(13)-SH.In comparison with the classic phosphine-halide-protected Au_(11)-Cl and Au_(13)-Cl,the Cl-to-thiol alteration triggered room-temperature luminescence of the Au_(11)core and dramatically modulated that of the Au_(13)core.Ultrafast ultraviolet/infrared(UV/IR)spectroscopy,which is sensitive to organic aromatic groups,together with ultrafast transient absorption(TA)spectroscopy unprecedently revealed a relaxation process from the ligand to core state affecting the dynamics in excited states and some critical intermediate states favouring efficient room-temperature emission of these nanoclusters.This work provides some new insights into the origin of photoluminescence of metal nanoclusters and opens an avenue to modulate the dynamics of their excited states using aromatic ligands,which would have direct applications in lighting,light harvesting,and photocatalysis.

Biothiols such as cysteine(Cys),bomocysteine(Hcy) and glutathione(GSH) play vital roles in a wide range of physiological and pathological processes arising from their biological redox chemistry. In addition,biothiols are closely associated with proteolysis in the lysosome w-hich reduces disulphide bonds. Therefore,selective determination of biothiols is of great importance for various investigations in biochemistry.In this work,we continue to investigate the impact of delicate modulations on the sensing ability.Therefore,we designed and developed 1,7-dimethyl,3,5-diaryl substituted BODIPY and its conformationally restricted species with meso-arylmercapto moiety(DM-BDP-SAr and DM-BDP-R-SAr) as selective fluorescent probes for Cys.Moreover,the lysosome-target probes(Lyso-S and Lyso-D) based on DM-BDP-SAr carrying one or two morpholinoethoxy moieties were developed(Fig.1).They were able to detect Cys selectively in vitro with low detection limits.Both Lyso-S and Lyso-D localized nicely in lysosomes in living HeLa cells and exhibited red fluorescence for Cys.Moreover,a novel fluorescence quenching mechanism was proposed from the calculations by density functional theory(DFT).The probes may go through intersystem crossing(from singlet excited state to triplet excited state) to result in fluorescence quenchin.

Atherosclerosis is a leading cause of mortality and morbidity worldwide.Despite the challenges in managing atherosclerosis,researchers continue to investigate new treatments and complementary therapies.Cordyceps is a traditional Chinese medicine that has recently gained attention as a potential therapeutic agent for atherosclerosis.Numerous studies have demonstrated the effectiveness of cordyceps in treating atherosclerosis through various pharmacological actions,including anti-inflammatory and antioxidant activities,lowering cholesterol,inhibiting platelet aggregation,and modulating apoptosis or autophagy in vascular endothelial cells.Notably,the current misuse of the terms cordyceps and Ophiocordyceps sinensis has caused confusion among researchers,and complicated the current academic research on cordyceps.This review focuses on the chemical composition,pharmacological actions,and underlying mechanisms contributing to the anti-atherosclerotic effects of cordyceps and the mycelium of Ophiocordyceps spp.This review provides a resource for the research on the development of new drugs for atherosclerosis from cordyceps.

Objective Innate lymphoid cells(ILCs)are a class of newly discovered immunocytes.Group 1 ILCs(ILC1s)are identified in the decidua of humans and mice.High mobility group box 1(HMGB1)is predicted to be one of the target genes of miR-142-3p,which is closely related to pregnancy-related diseases.Furthermore,miR-142-3p and HMGB1 are involved in regulating the NF-κB signaling pathway.This study aimed to examine the regulatory effect of miR-142-3p on ILC1s and the underlying mechanism involving HMGB1 and the NF-κB signaling pathway.Methods Mouse models of normal pregnancy and abortion were constructed,and the alterations of ILC1s,miR-142-3p,ILC1 transcription factor(T-bet),and pro-inflammatory cytokines of ILC1s(TNF-α,IFN-γand IL-2)were detected in mice from different groups.The targeting regulation of HMGB1 by miR-142-3p in ILC1s,and the expression of HMGB1 in normal pregnant mice and abortive mice were investigated.In addition,the regulatory effects of miR-142-3p and HMGB1 on ILC1s were detected in vitro by CCK-8,Annexin-V/PI,ELISA,and RT-PCR,respectively.Furthermore,changes of the NF-κB signaling pathway in ILC1s were examined in the different groups.For the in vivo studies,miR-142-3p-Agomir was injected in the uterus of abortive mice to evaluate the abortion rate and alterations of ILC1s at the maternal-fetal interface,and further detect the expression of HMGB1,pro-inflammatory cytokines,and the NF-κB signaling pathway.Results The number of ILC1s was significantly increased,the level of HMGB1 was significantly upregulated,and that of miR-142-3p was considerably downregulated in the abortive mice as compared with the normal pregnant mice(all Psignaling pathway(Psignificantly downregulated and the activation of the NF-κB signaling pathway was inhibited in the miR-142-3p Agomir group(all Psion miR-142-3p can regulate ILC1s by targeting HMGB1

The relativistic mean-field approach was implemented in the Lanzhou quantum molecular dynamics transport model(LQMD.RMF). Using the LQMD.RMF, the properties of collective flow and pion production were investigated systematically for nuclear reactions with various isospin asymmetries. The directed and elliptic flows of the LQMD.RMF are able to describe the experimental data of STAR Collaboration. The directed flow difference between free neutrons and protons was associated with the stiffness of the symmetry energy, that is, a softer symmetry energy led to a larger flow difference. For various collision energies, the ratio between the π^(-) and π^(+) yields increased with a decrease in the slope parameter of the symmetry energy. When the collision energy was 270 MeV/nucleon, the single ratio of the pion transverse momentum spectra also increased with decreasing slope parameter of the symmetry energy in both nearly symmetric and neutron-rich systems.However, it is difficult to constrain the stiffness of the symmetry energy with the double ratio because of the lack of threshold energy correction on the pion production.
