Aqueous electrochromic battery（ECB） has shown intense potential for achieving energy storage and saving simultaneously.While tungsten oxide（WO3） is the most promising EC material for commercialization,the cycling stability of WO3-based aqueous ECBs is currently unsatisfactory due to the repeated phase transition during the redox process and the corrosion by acidic electrolytes.Herein,we present a titanium-tungsten oxide alloy（Ti-WO3） with controllable morphology and crystal phase synthesized by a facile hot injection method to overcome the challenges.In contrast to conventional monoclinic WO3,the Ti-WO3nanorods can stably maintain their cubic crystal phase during the redox reaction in an acidic electrolyte,thus leading to dramatically enhanced response speed and cycling stability,Specifically,when working in a well-matched hybrid Al3+/Zn2+aqueous electrolyte,our phasetransition-free cubic Ti-WO3exhibits an ultra-high cycling stability（>20000 cycles）,fast response speed（3,95 s/4,65 s for bleaching/coloring）,as well as excellent discharge areal capacity of 214.5 mA h m-2,We further fabricate a fully complementa ry aqueous electrochromic device,for the first time,using a Ti-WO3/Prussian blue device architecture.Remarkably,the complementary ECB shows>10000 stable operation cycles,attesting to the feasibility of our Ti-WO3for practical applications.Our work validates the significance of inhibiting the phase transitions of WO3during the electrochromic process for realizing highly cyclable aqueous ECB,which can possibly provide a generalized design guidance for other high-quality metallic oxides for electrochemical applications.

作为儒家教化思想的重要组成部分,荀子道德教化思想在传统与近现代社会中都具有不可忽视的影响。伴随现代化的发展,与传统相对的“现代性”在制度结构、价值理念与个体精神气质上引起的整体变化和秩序转型给当代社会的道德建设带来了新挑战,具体表现为工具理性与价值理性的张裂、个体与共同体的疏离、规训与教化的悖反。但现代性的发展及其弊端的破解离不开其所植根的文化传统。荀子从重构社会秩序的现实出发来考察人与社会的存在,其教化思想内蕴着理性与情感互渗、个体与群体统一、规范与德性融合的价值特质,可以为当今社会的人格重塑、人与社会的秩序关系重构提供重要的文化资源。

Smart manufacturing still remains critical challenges for pharmaceutical manufacturing.Here,an original data-driven engineering framework was proposed to tackle the challenges.Firstly,from sporadic indicators to five kinds of systematic quality characteristics,nearly 2,000,000 real-world data points were successively characterized from Ginkgo Folium tablet manufacturing.Then,from simplex to the multivariate system,the digital process capability diagnosis strategy was proposed by multivariate C_(pk)integrated Bootstrap-t.The C_(pk)of Ginkgo Folium extracts,granules,and tablets were discovered,which was 0.59,0.42,and 0.78,respectively,indicating a relatively weak process capability,especially in granulating.Furthermore,the quality traceability was discovered from unit to end-to-end analysis,which decreased from 2.17 to 1.73.This further proved that attention should be paid to granulating to improve the quality characteristic.In conclusion,this paper provided a data-driven engineering strategy empowering industrial innovation to face the challenge of smart pharmaceutical manufacturing.

Oligoasthenospermia is the primary cause of infertility.However,there are still enormous challenges in the screening of critical candidates and targets of oligoasthenospermia owing to its complex mechanism.In this study,stem cell factor(SCF),c-kit,and transient receptor potential vanilloid 1(TRPV1)biosensors were successfully established and applied to studying apoptosis and autophagy mechanisms.Interestingly,the detection limit reached 2.787×10^(-15)g/L,and the quantitative limit reached 1.0×10^(-13)g/L.Furthermore,biosensors were used to investigate the interplay between autophagy and apoptosis.Schisandrin A is an excellent candidate to form a system with c-kit similar to SCF/c-kit with a detection constant(K_(D))of 5.701×10^(-11)mol/L,whereas it had no affinity for SCF.In addition,it also inhibited autophagy in oligoasthenospermia through antagonizing TRPV1 with a K_(D) of up to 4.181×10^(-10)mol/L.In addition,in vivo and in vitro experiments were highly consistent with the biosensor.In summary,high-potency schisandrin A and two potential targets were identified,through which schisandrin A could reverse the apoptosis caused by excessive autophagy during oligoasthenospermia.Our study provides promising insights into the discovery of effective compounds and potential targets via a well-established in vitro-in vivo strategy.

Switching the reaction routes in peroxymonosulfate(PMS)-based advanced oxidation processes have attracted much attention but remain challenging.Herein,a series of Co-N/C catalysts with different compositions and structures were prepared by using bimetallic zeolitic imidazolate frameworks based on ZIF-8 and ZIF-67(x Zn/Co-ZIFs).Results show that Co doping amount could mediate the transformation of the activation pathway of PMS over CoN/C.When Co doping amount was less than 10%,the constructed x Co-N/C/PMS system(x≤10%)was singlet oxygen-dominated reaction;however further increasing Co doping amount would lead to the generation and coexistence of sulfate radicals and high-valent cobalt,besides singlet oxygen.Furthermore,the nitrogen-coordinated Co(Co-NX)sites could serve as main catalytically active sites to generate singlet oxygen.While excess Co doping amount caused the formation of Co nanoparticles from which leached Co ions were responsible for the generation of sulfate radicals and high-valent cobalt.Compared to undoped N/C,Co doping could significantly enhance the catalytic performance.The 0.5%Co-N/C could achieve the optimum degradation(0.488 min^(-1))and mineralization abilities(78.4%)of sulfamethoxazole among the investigated Co-N/C catalysts,which was superior to most of previously reported catalysts.In addition,the application prospects of the two systems in different environmental scenarios(pH,inorganic anions and natural organic matter)were assessed and showed different degradation behaviors.This study provides a strategy to regulate the reactive species in PMS-based advanced oxidation process.

Neural Regeneration Research 2024年第11期19卷 2411-2420页

作者： Shuangchan wu Wensheng Lin Department of Neuroscience University of MinnesotaMinneapolisMNUSA Institute for Translational Neuroscience University of MinnesotaMinneapolisMNUSA

The unfolded protein response(UPR)is a cellular stress response pathway activated when the endoplasmic reticulum,a crucial organelle for protein folding and modification,encounters an accumulation of unfolded or misfolded proteins.The UPR aims to restore endoplasmic reticulum homeostasis by enhancing protein folding capacity,reducing protein biosynthesis,and promoting protein degradation.It also plays a pivotal role in coordinating signaling cascades to determine cell fate and function in response to endoplasmic reticulum stress.Recent research has highlighted the significance of the UPR not only in maintaining endoplasmic reticulum homeostasis but also in influencing various physiological processes in the nervous system.Here,we provide an overview of recent findings that underscore the UPR’s involvement in preserving the function and viability of neuronal and myelinating cells under physiological conditions,and highlight the critical role of the UPR in brain development,memory storage,retinal cone development,myelination,and maintenance of myelin thickness.
