The issues of fossil energy shortage and environmental pollution caused by the excessive consumption of conventional fossil fuels necessitates the exploration of renewable and clean energy sources such as hydrogen,which is viable alternative to traditional energy sources in view of its high energy density and nonpolluting nature.In this regard,photocatalytic technology powered by inexhaustible solar energy is an ideal hydrogen production method.The recently developed copper-and zinc-based multinary metal sulfide(MMS)semiconductor photocatalysts exhibit the advantages of suitable bandgap,wide light-harvesting range,and flexible elemental composition,thus possessing great potential for achieving considerable photocatalytic hydrogen evolution(PHE)performance.Despite great progress has been achieved,the current photocatalysts still cannot meet the commercial application demands,which highlights the mechanisms understanding and optimization strategies for efficient PHE.Herein,the basic mechanisms of PHE,and effective optimization strategies are firstly introduced.Afterwards,the research process and the performance of copper-and zinc-based MMS photocatalysts,are thoroughly reviewed.Finally,the unresolved issues,and challenges hindering the achievement of overall water splitting have been discussed. 展开更多

Active sulfur dissolution and shuttle effect of lithium polysulfides(LiPSs)are the main obstacles hindering the practical application of lithium-sulfur batteries(LSBs),which is primarily induced by the direct interaction between sulfur-loading cathode and liquid electrolyte.The introduction of functional interlayer within the separator and cathode is an effective strategy to stabilize the electrode/electrolyte interface reaction and improve the utilization rate of active sulfur.Herein,conductive composite nanofabrics(CCN)with multifunctional groups are employed as the interlayer of sulfur-loading cathode,in which the PMIA/PAN supporting fibers offer robust mechanical strength and high thermostable performance,and gelatin/polypyrrole functional fibers ensure high electrical conductivity and strong chemical interaction for LiPSs.As demonstrated by the experimental data and material characterizations,the presence of CCN interlayer not only blocks the shuttle behavior of LiPSs,but also strengthens the interface stability of both Li anode and sulfur-loading cathode.Interestingly,the assembled LSBs with CCN interlayer can maintain stable capacity of 686 mAh/g after 200 cycles at 0.5 A/g.This work will provide new ideas for the elaborate design of functional in terlayers/se para tors for LSBs and lithium metal batteries. 展开更多

The practical application of lithium-sulfur(Li-S)batteries is still impeded by the severe shuttle effect of lithium polysulfides(LiPSs)and sluggish reaction kinetics of active sulfur.Designing catalytic carriers with abundant active sites and strong chemisorption capability for LiPSs,is regarded as effective strategy to address these issues.Herein,Se-doping is introduced into the nitrogen-doped carbon coated CoP composite(Se-CoP@NC)to generate structural defects,which effectively enlarges the lattice spacing of CoP and reduces the conversion reaction energy barriers of LiPSs.Meanwhile,Se-doping sites bridges the interface of CoP and nitrogen-doped carbon,accelerating the charge transfer behavior and conversion reaction kinetics of LiPSs.Benefiting from the structural advantages,the assembled Li-S batteries with S/Se-CoP@NC as cathode exhibit high reversible capacity of 779.6 mAh/g at 0.5 C after 500 cycles,and high specific capacity of 805.9 mAh/g at 2 C.Even under extreme conditions(high sulfur-loading content of 6.9 mg/cm^(2);lean electrolyte dosage of 7μL/mg),the corresponding Li-S batteries also keep high reversible areal capacity of 4.5 mAh/cm^(2) after 100 cycles at 0.1 C.This work will inspire the design of metal compounds-based catalysts from atomic level to facilitate the practicability of Li-S batteries. 展开更多

Sluggish conversion reaction kinetics and spontaneous shuttle effect of lithium polysulfides(LiPSs)are deemed as the two big mountains that hinder the practical application of lithium-sulfur batteries(LSBs).Herein,dual-defect engineering strategy is implemented by introducing boron-doping and phosphorusvacancy sites with MoP@NC composite as the precursor.Based on the experimental characterizations and theoretical calculations,B-MoP_(1-x)@NC-based electrode presents low oxidation potential,high lithium diffusivity,small Tafel slope and strong adsorption capability for polysulfides,which is beneficial to enhance the adsorption capability for LiPSs,reduce the lithium diffusion energy barriers and Gibbs free energy for the conversion reactions of LiPSs.As demonstrated,the corresponding Li-S/B-MoP1-x@NC batteries can remain high reversible capacity of 753 mAh/g at 0.5 C after 300 cycles,and keep a stable capacity of 520 mAh/g at 0.5 C after 100 cycles even at the high-loading content of 5.1mg/cm^(2).According to the results of in-situ UV–vis spectra,the satisfactory battery performance majorly originates from the existence of dual-defect characteristics in B-MoP1-x@NC catalyst,which effectively promotes the conversion reaction kinetics of LiPSs,and restrains the shuttle behavior of LiPSs.The key ideas of this work will enlighten the development of catalytic cathode materials for sulfur-based secondary batteries. 展开更多

Lithium-ion batteries(LIBs)are increasingly required to operate under harsh conditions,particularly at low-temperature condition.Developing novel electrolytes is a facile and effective approach to elevate the electrochemical performances of LIBs at low temperature.Herein,a dual-salt electrolyte consisting of(lithium bis(trifluoromethanesulfonyl)imide(Li TFSI)and lithium difluoro(oxalato)borate(Li ODFB))is proposed to regulate the solvation structure of Li^(+) ions and improve the reaction kinetics under low temperature.Based on the comprehensive electrochemical tests and theoretical computations,the introduction of LiODFB component not only effectively benefits the formation of cathode electrolyte interface(CEI)layer on the surface of LiFePO_(4) electrode,but also inhibits the chemical corrosion effect of Li TFSIcontaining electrolytes on Al foil.As expected,the optimized Li||LiFePO_(4) cells can display high reversible capacity of 117.0 m Ah/g after 100 cycles at-20℃.This work provides both theoretical basis and experimental guidance for the rational design of low-temperature resistant electrolytes. 展开更多

Energy storage plays a critical role in sustainable development,with secondary batteries serving as vital technologies for efficient energy conversion and utilization.This review provides a comprehensive summary of recent advancements across various battery systems,including lithium-ion,sodium-ion,potassium-ion,and multivalent metal-ion batteries such as magnesium,zinc,calcium,and aluminum.Emerging technologies,including dual-ion,redox flow,and anion batteries,are also discussed.Particular attention is given to alkali metal rechargeable systems,such as lithium-sulfur,lithium-air,sodium-sulfur,sodium-selenium,potassium-sulfur,potassium-selenium,potassium-air,and zinc-air batteries,which have shown significant promise for high-energy applications.The optimization of key components—cathodes,anodes,electrolytes,and interfaces—is extensively analyzed,supported by advanced characterization techniques like time-of-flight secondary ion mass spectrometry(TOF-SIMS),synchrotron radiation,nuclear magnetic resonance(NMR),and in-situ spectroscopy.Moreover,sustainable strategies for recycling spent batteries,including pyrometallurgy,hydrometallurgy,and direct recycling,are critically evaluated to mitigate environmental impacts and resource scarcity.This review not only highlights the latest technological breakthroughs but also identifies key challenges in reaction mechanisms,material design,system integration,and waste battery recycling,and presents a roadmap for advancing high-performance and sustainable battery technologies. 展开更多

The notorious shuttle effect of polyiodides in aqueous Zinc-iodine(Zn-I2)batteries impedes their practical application,which renders it imperative to address this issue.Here,we report natural gelatin as an advanced aqueous binder for iodine-loading cathode to enable stable and efficient Zn-I_(2) batteries.The positively charged region in gelatin presents electrostatic attraction to the iodine species,while the electron-rich regions could donate electrons to form physical or even covalent bonds with iodine species,thus inhibiting polyiodides shuttle effect and boosting redox reaction.A high reversible capacity of 138 mAh g^(-1) after 3000 cycles at 2C and an ultra-long cycling stability of 30000 cycles at 25C with 107 mAh g^(-1) capacity was achieved.Gelatin binder also can accommodate high iodine-loading(~10 mg)cathode,punch cells,and severe temperature conditions(-10℃ and 60℃).In-situ UV-vis absorption spectroscopy,in-situ Raman spectra and theoretical calculation revealed the critical role of gelatin binder in suppressing polyiodide shuttling and accelerating reaction kinetics.This work uncovers the potential of natural low-cost binder material in advanced Zn-I_(2) batteries and drives future study of designing functional binders. 展开更多

The realization of high-efficiency photocatalysis is greatly meaningful to overcome the issues of current energy and environment,in which the core factor is the exploration of photocatalysts with promising semiconductor properties.The Cu-based metal sulfide photocatalysts of CuSbS_(2)and its derivative of bournonite CuPbSbS_(3)possess the features of earth-abundant elements,strong photostability,visiblelight range bandgap,and high absorption coefficient,possessing great potential for the realization of efficient photocatalytic applications.Although the photocatalysts of CuSbS_(2)and CuPbSbS_(3)have been investigated in photocatalysis application of hydrogen production and degradation,the exploration process is still in the early-development stage.In this review,the design concept and semiconductor properties of CuSbS_(2)and CuPbSbS_(3)are firstly introduced.Subsequently,the photocatalytic applications of CuSbS_(2)and CuPbSbS_(3)photocatalysts,mainly including hydrogen production and degradation,are systematically reviewed.Finally,the challenges and prospects for the further exploration of CuSbS_(2)and CuPbSbS_(3)photocatalysts are provided. 展开更多

Gel polymer electrolytes(GPEs)with high flame‐retardant concentration can remarkably reduce the thermal runaway risk of lithium metal batteries(LMBs).However,higher flame‐retardant content in GPEs always leads to increased leakage of active component and severe lithium corrosion,which greatly hinders the service life of LMBs.Herein,GPEs with high‐loading triphenyl phosphate(TPP)are originally fabricated by coaxial electrospinning and stabilized by dual confinement effects,including chemisorption of polyvinylidene fluoride‐hexafluoropropylene(PVDF‐HFP),and physical encapsulation of polyacrylonitrile(PAN)/PVDF‐HFP.These effects arise from the strong polar interactions between the−CF3 group in PVDF‐HFP and P=O group in TPP,as well as the superior anti‐swelling property of PAN.To mitigate TPP‐induced corrosion during cycling,the optimized Li anode is armored with LiF‐rich solid electrolyte interphase(SEI)layer through immersing it in fluoroethylene carbonate‐containing electrolyte.As expected,the corresponding Li||Li symmetric cells deliver long‐term stable cycling behavior over 2400 h at 0.5 mA cm−2,and the LiFePO4||Li batteries hold a high‐capacity retention ratio of 81.7%after 6000 cycles at 10 C with excellent flame retardancy.These findings offer new insight into designing the SEI layer for lithium metal in flame‐retardant electrolytes,thus promoting the development and application of high‐security LMBs. 展开更多

In this paper,a robust decoupled sliding mode control(RDSMC)is proposed for active suspension system(ASS)to balance the trade-off between ride comfort and road holding.The ASS is decoupled into two subsystems:a sprung-mass subsystem(regarding ride comfort)and an unsprung-mass subsystem(regarding road holding),which correspond to two prescribed performance tracking problems.Subsequently,an integrated control law is designed by introducing the unsprung-mass sliding surface into the control of the sprung-mass one.To reduce chattering and stabilize the subsystems,a prescribed-time extended disturbance observer(PT-EDO)is designed,achieving the time-varying switching gain RDSMC(TVSG-RDSMC).Numerical simulations imply that the proposed TVSG-RDSMC can effectively improve ride comfort and road holding with a significantly reduced chattering. 展开更多

Potassium-ion batteries(KIBs)have great potential for applications in large-scale energy storage devices.However,the larger radius of K+leads to sluggish kinetics and inferior cycling performance,severely restricting its practical applicability.Herein,we propose a rational strategy involving a Prussian blue analogue-derived graphitized carbon anode with fast and durable potassium storage capability,which is constructed by encapsulating cobalt nanoparticles in nitrogen-doped graphitized carbon(Co-NC).Both experimental and theoretical results show that N-doping effectively promotes the uniform dispersion of cobalt nanoparticles in the carbon matrix through Co-N bonds.Moreover,the cobalt nanoparticles and strong Co-N bonds synergistically form a threedimensional conductive network,increase the number of adsorption sites,and reduce the diffusion energy barrier,thereby facilitating the adsorption and the diffusion kinetics.These multiple effects lead to enhanced reversible capacities of 305 and 208.6 mAh g^−1 after 100 and 300 cycles at 0.05 and 0.1 A g^−1,respectively,demonstrating the applicability of the Co-NC anode for KIBs. 展开更多

Polyploid plants grow well,are stress tolerant,and are rich in nutrients and bioactive compounds.Thus,they are useful for improving crop quality and yield.In this study,we compared the seed characteristics and metabolite profiles of diploid and tetraploid tartary buckwheat,which was developed via an artificially induced chromosome doubling event.The length,width,area,and thousand-grain weight were greater for the tetraploid seeds than for the diploid seeds.However,the germination rate decreased for the tetraploid seeds.Additionally,there was a gap between the shell and kernel of the tetraploid seeds.Moreover,the water absorption rate was higher for the tetraploid than for the diploid seeds.Chromosome doubling increased the seed total flavonoid content and deepened the seed color.A principal component analysis of the ultrahigh-pressure liquid chromatography-high resolution mass spectrometry data revealed the clear separation between the diploid and tetraploid samples.An orthogonal partial least squares-discriminant analysis and other multivariate statistical analyses identified 83 differentially abundant compounds,with most of the flavonoid metabolites more abundant in the tetraploid than in the diploid seeds.Research on tartary buckwheat polyploidy may result in enhanced germplasm resources and may clarify the mechanism underlying the biosynthesis of bioactive compounds. 展开更多

Magnoliae officinalis is the plant source of houpo, a widely used traditional Chinese medicine to treat symptoms of gastrointestinal diseases. Its main active components, magnolol (MG) and honokiol (HK), have excellent pharmacological actions, but little research has focused on the functional genes involved in the MG and HK metabolic pathways. In this study, using RNA-seq and gene expression profile, we present the first transcriptome characterization of M. officinalis leaves, twigs and stems. Based on similarity search against nonredundant protein databases, 30,660 contigs had at least a significant alignment to existing public database. Pathway analysis showed that 8707 contigs were assigned to 317 KEGG pathways. A second skeleton pathway with 14 putative homologous genes was also identified as involved in lignan biosynthesis. Expression profiles of these 14 genes showed that leaves and twigs seem to have higher transcript levels for lignan components than in stem tissue; this result was then verified by qRT-PCR. Our work will immensely facilitate metabolic research on lignan biosynthesis in M. officinalis. 展开更多

Both sodium-ion batteries(SIBs)and potassium-ion batteries(PIBs)are considered as promising candidates in grid-level energy storage devices.Unfortunately,the larger ionic radii of K+and Na+induce poor diffusion kinetics and cycling stability of carbon anode materials.Pore structure regulation is an ideal strategy to promote the diffusion kinetics and cyclic stability of carbon materials by facilitating electrolyte infiltration,increasing the transport channels,and alleviating the volume change.However,traditional pore-forming agent-assisted methods considerably increase the difficulty of synthesis and limit practical applications of porous carbon materials.Herein,porous carbon materials(Ca-PC/Na-PC/K-PC)with different pore structures have been prepared with gluconates as the precursors,and the amorphous structure,abundant micropores,and oxygen-doping active sites endow the Ca-PC anode with excellent potassium and sodium storage performance.For PIBs,the capacitive contribution ratio of Ca-PC is 82%at 5.0 mV s^(-1) due to the introduction of micropores and high oxygen-doping content,while a high reversible capacity of 121.4 mAh g^(-1) can be reached at 5 A g^(-1) after 2000 cycles.For SIBs,stable sodium storage capacity of 101.4 mAh g^(-1) can be achieved at 2 A g^(-1) after 8000 cycles with a very low decay rate of 0.65%for per cycle.This work may provide an avenue for the application of porous carbon materials in the energy storage field. 展开更多

High-efficiency seawater electrolysis is impeded by the low activity and low durability of oxygen evolution catalysts due to the complex composition and competitive side reactions in seawater.Herein,a heterogeneousstructured catalyst is constructed by depositing NiFe-layered double hydroxides(NiFe-LDH)on the substrate of MXene(V_(2)CT_(x))modified Ni foam(NF),and abbreviated as NiFe-LDH/V_(2)CT_(x)/NF.As demonstrated,owing to the intrinsic negative charge characteristic of V_(2)CT_(x),chlorine ions are denied entry to the interface between NiFeLDH and V_(2)CT_(x)/NF substrate,thus endowing NiFe-LDH/V_(2)CT_(x)/NF catalyst with high corrosion resistance and durable stability for 110 h at 500 mA cm^(-2).Meanwhile,the two-dimensional structure and high electrical conductivity of V_(2)CT_(x) can respectively enlarge the electrochemical active surface area and guarantee fast charge transfer,thereby synergistically promoting the catalytic performance of NiFe-LDH/V_(2)CT_(x)/NF in both deionized water electrolyte(261 m V at 100 m A cm^(-2))and simulated seawater electrolyte(241 mV at 100 mA cm^(-2)).This work can guide the preparation of oxygen evolution catalysts and accelerate the industrialization of seawater electrolysis. 展开更多

Extensive in vitro and in vivo research reveals multiple intracellular molecular targets of Antrodia camphorata,and these targets affect growth,apoptosis,angiogenesis,invasion and metastasis of cells.These targets include tumor suppressor,cell cycle regulator,transcription factor,angiogenesis and metastasis factor,apoptosis and survival regulator,etc.Additionally,more and more attention has been paid to the molecular mechanism of A.camphorata on the regulation of tumor stem cells.Meanwhile,there is evidence that the immunoregulation of A.camphorata is enhanced,which may lead cell cycle arrest or apoptosis.In this paper,molecular mechanism of tumor cells and tumor stem cells regulated at multiple targets by A.camphorata in vitro and in vivo in the past decade is summarized. 展开更多
