Zinc ion batteries are considered as potential energy storage devices due to their advantages of low-cost,high-safety,and high theoretical capacity.However,dendrite growth and chemical corrosion occurring on Zn anode limit their commercialization.These problems can be tackled through the optimization of the electrolyte.However,the screening of electrolyte additives using normal electrochemical methods is time-consuming and labor-intensive.Herein,a fast and simple method based on the digital holography is developed.It can realize the in situ monitoring of electrode/electrolyte interface and provide direct information concerning ion concentration evolution of the diffusion layer.It is effective and time-saving in estimating the homogeneity of the deposition layer and predicting the tendency of dendrite growth,thus able to value the applicability of electrolyte additives.The feasibility of this method is further validated by the forecast and evaluation of thioacetamide additive.Based on systematic characterization,it is proved that the introduction of thioacetamide can not only regulate the interficial ion flux to induce dendrite-free Zn deposition,but also construct adsorption molecule layers to inhibit side reactions of Zn anode.Being easy to operate,capable of in situ observation,and able to endure harsh conditions,digital holography method will be a promising approach for the interfacial investigation of other battery systems.

The severe dependence of traditional phase change materials(PCMs)on the temperature-response and lattice deficiencies in versatility cannot satisfy demand for using such materials in complex application scenarios.Here,we introduced metal ions to induce the self-assembly of MXene nanosheets and achieve their ordered arrangement by combining suction filtration and rapid freezing.Subsequently,a series of MXene/K^(+)/paraffin wax(PW)phase change composites(PCCs)were obtained via vacuum impregnation in molten PW.The prepared MXene-based PCCs showed versatile applications from macroscale technologies,successfully transforming solar,electric,and magnetic energy into thermal energy stored as latent heat in the PCCs.Moreover,due to the absence of binder in the MXene-based aerogel,MK3@PW exhibits a prime solar-thermal conversion efficiency(98.4%).Notably,MK3@PW can further convert the collected heat energy into electric energy through thermoelectric equipment and realize favorable solar-thermal-electric conversion(producing 206 mV of voltage with light radiation intensity of 200 mw cm^(−2)).An excellent Joule heat performance(reaching 105℃with an input voltage of 2.5 V)and responsive magnetic-thermal conversion behavior(a charging time of 11.8 s can achieve a thermal insulation effect of 285 s)for contactless thermotherapy were also demonstrated by the MK3@PW.Specifically,as a result of the ordered arrangement of MXene nanosheet self-assembly induced by potassium ions,MK3@PW PCC exhibits a higher electromagnetic shielding efficiency value(57.7 dB)than pure MXene aerogel/PW PCC(29.8 dB)with the same MXene mass.This work presents an opportunity for the multi-scene response and practical application of PCMs that satisfy demand of next-generation multifunctional PCCs.

To address the low conductivity and easy agglomeration of transition metal sulfide nanoparticles,FeCoS_(4) nanoparticles embedded in S-doped hollow carbon(FeCoS_(4)@S-HC)composites were successfully fabricated through a combination of hydrothermal processes and sulfidation treatment.The unique bowlshaped FeCoS_(4)/S-HC composites exhibit excellent structural stability with a high specific surface area of 303.7 m^(2)·g^(-1) and a pore volume of 0.93 cm^(3)·g^(-1).When applied as anode material for lithium-ion batteries,the FeCoS_(4)@S-HC anode exhibits efficient lithium storage with high reversible specific capacity(970.2 mA·h·g^(-1) at 100 mA·g^(-1))and enhanced cycling stability(574 mA·h·g^(-1) at 0.2 A·g^(-1) after 350 cycles,a capacity retention of 84%).The excellent lithium storage is attributed to the fact that the bimetallic FeCoS_(4) nanoparticles with abundant active sites can accelerate the electrochemical reaction kinetics,and the bowl-shaped S-HC structure can provide a stable mechanical structure to suppress volume expansion.

Background:Although it has been established that the human Solute Carrier Family 22(SLC22)functions as a cationic transporter,influencing cellular biological metabolism by modulating the uptake of various cations,its impact on cancer prognosis remains unclear.Methods:We conducted a comprehensive analysis utilizing data from The Cancer Genome Atlas(TCGA)and other databases to assess the prognostic value and functional implications across various tumors.Silence of SLC22A1 RNA in glioma U251 cells was performed to access the impact of SLC22A1 on lowergrade glioma(LGG)progression.Results:Our findings demonstrated a significant correlation between SLC22A1 expression and the survival time of patients with various cancers(p1 in occurrence and progress of certain cancers,with a pronounced impact on LGG.Further examination of the SLC22A1-LGG relationship revealed its status as an independent risk factor for LGG,suggesting its potential involvement in regulating diverse immune pathways and metabolic activities.Chinese Glioma Genome Atlas(CGGA)data supported the reliability of the risk score as a prognostic and recurrence indicator,emphasizing the accuracy of the nomograph(1,3,and 5-year-AUC>0.8).Cell proliferation and clone formation experiment proved that decreased expression of SLC22A1 in glioma U251 cells inhibited glioma cell growth.Conclusion:Our findings suggest SLC22A1 has huge prospects as a promising biomarker and therapeutic target for LGG prognosis.SLC22A1 has only been proved to support cellular function previously.Our findings demonstrated a robust connection between the tumor microenvironment and functional proteins that maintain basal cell metabolism,which gifts unique tumor immune characteristics of gliomas.Additionally,we provide a highly practical prediction model for estimating the survival rate of LGG patients.

“职普融通”是优化职业教育类型定位、推进职业教育高质量发展的重要路径,为推进职业教育、劳动教育与实习融通提供了理论依据。我国新修订施行的《职业教育法》和新《职业学校学生实习管理规定》都确定了职业教育的基本目标是“立德树人、德技并修”,这为职业教育与劳动教育和实习的目标融通奠定了法制基础。“立德树人、德技并修”也是职业院校劳动教育及实习的目标;同时,普通高等教育中的劳动教育及实习也应当以之为目标。无论是职业教育,还是普通教育,劳动教育都需要与实习有机融通。融通之实践策略有:一是将劳动教育与实习有机融通;二是将劳动教育与就业见习融通;三是在思想政治课中进行劳动教育;四是单列劳动教育课程与劳动学分;五是在专业课程中融入劳动教育,将劳动教育元素融入“课程思政”之中。

“跨文化表演”的魅力在于“跨”,“跨文化表演训练”的难点也在于“跨”。所谓“跨界”,要有“界”才可“跨”。“边界”的存在,才使“跨”有必要和有价值。文化越成熟,其边界越分明,跨越也就愈艰难。而回到文化的“干细胞”层面,因边... 详细信息

“跨文化表演”的魅力在于“跨”,“跨文化表演训练”的难点也在于“跨”。所谓“跨界”,要有“界”才可“跨”。“边界”的存在,才使“跨”有必要和有价值。文化越成熟,其边界越分明,跨越也就愈艰难。而回到文化的“干细胞”层面,因边界消失,跨越将变得容易。借鉴戏剧人类学“前表意性训练”,回到“分化”之前没有“边界”的“原初”,进入文化“干细胞”层次,可以找到跨文化表演训练的路径,在边界消失地带实现文化屏障的跨越。

植根于爵士乐,科特兹的诗歌文本摹仿非洲音乐元素,如环唱、爵士变奏、即兴重复等,赋予诗歌以音乐性和表演性,实现跨艺术性和跨媒介性指涉。她以音乐和朗诵/吟唱形式将诗歌进行转换与生产,录制唱片与CD,实现跨艺术文本的转换或媒介性迁移。她在与喷火者乐队的现场表演中完成人声、音乐与器乐的媒介组合,以小型剧场的艺术形式传达诗歌的内涵。科特兹在现场表演中强调即兴创作、声音的力量和音调的变化,这种表演既恢复了诗歌被印刷遮蔽的语音和听觉效果,又能充分调动观众的感官和情感体验。诗人、观众与音乐共振,制造了剧场效果。音乐、电子与数字媒体技术等多媒介共同影响了科特兹诗歌的创作、阅读和表演,并参与了诗歌美学意义的建构,使其诗歌从单一的艺术走向跨艺术,从单一的媒介走向跨媒介。本文借助跨艺术诗学与跨媒介性理论,探讨科特兹的表演诗歌如何将文本、音乐和现场表演实行三位一体的融合,以独特而又创新的方式传递诗歌意义。对科特兹表演诗歌的跨艺术性和跨媒介性研究有助于挖掘其诗学建构与实践及其对美国当代实验性诗学的重要贡献。
