Spinal cord injury(SCI)is a serious clinical disease.Due to the deformability and fragility of the spinal cord,overly rigid hydrogels cannot be used to treat SCI.Hence,we used TPA and Laponite to develop a hydrogel with shear-thinning ability.This hydrogel exhibits good deformation,allowing it to match the physical properties of the spinal cord;additionally,this hydrogel scavenges ROS well,allowing it to inhibit the lipid peroxidation caused by ferroptosis.According to the in vivo studies,the TPA@Laponite hydrogel could synergistically inhibit ferroptosis by improving vascular function and regulating iron metabolism.In addition,dental pulp stem cells(DPSCs)were introduced into the TPA@Laponite hydrogel to regulate the ratios of excitatory and inhibitory synapses.It was shown that this combination biomaterial effectively reduced muscle spasms and promoted recovery from SCI.

Lithium metal anode(LMA)is the ultimate"Holy Grail"electrode for next generation high-energy-density batteries.Nevertheless,its instinct high reactivity is a formidable challenge and has intensified side reactions,destabilized the electrode/electrolyte interface and restricted the operating conditions strictly,thus hampering its practical application.Here,we"make up"the Li metal(M-Li)by constructing vaselinecoated layer by a simple dip-coating or casting method.With the chemically stable and hydrophobic vaseline protective layer,the stability of Li towards humid and corrosive atmosphere has been greatly improved.The M-Li guaranteed stable and prolonged cycling life after the anode suffering from corrosion in moist air(relative humidity-65%)or corrosive electrolyte(with 10,000 ppm H2O or S)both in symmetric cells and LiFePO4 full cells.This work illustrates a convenient,economic,and industrial applicable method for stable LMA.

Cell-based transplantation strategies possess great potential for spinal cord injury(SCI)repair.Basic fibroblast growth factor(bFGF)has been reported to have multiple neuro-promoting effects on developing and adult nervous system of mammals and considered a promising therapy for nerve injury following SCI.Human dental pulp stem cells(DPSCs)are abundant stem cells with low immune rejection,which can be considered for cell replacement therapy.The purpose of this study was to investigate the roles of DPSCs which express bFGF under the regulation of five hypoxia-responsive elements(5HRE)using an adeno-associated virus(AAV-5HRE-bFGF-DPSCs)in SCI repairing model.In this study,DPSCs were revealed to differentiate into CD13^(+)pericytes and up-regulate N-cadherin expression to promote the re-attachment of CD13^(+)pericytes to vascular endothelial cells.The re-attachment of CD13^(+)pericytes to vascular endothelial cells subsequently increased the flow rate of blood in microvessels via the contraction of protuberance.As a result,increased numbers of red blood cells carried more oxygen to the damaged area and the local hypoxia microenvironment in SCI was improved.Thus,this study represents a step forward towards the potential use of AAV-5HRE-bFGF-DPSCs in SCI treatment in clinic.

Tetracycline is a typical antibiotic commonly used in various industries which is eco-toxic and quickly causes bacterial resistance.Therefo re,studying the efficient removal of tetracycline is necessary to protect the water environment.Herein,a novel Ce/Fe nanoparticle composite(1CCFO)was prepared by the sol-gel method and its removal effects of tetracycline under visible light were performed.The relationship between physicochemical properties of catalyst and photocatalytic degradation effects of tetracycline was analyzed based on a series of characterizations data such as X-ray diffraction(XRD),Raman spectro scopy,a vibrating sample magnetometer(VSM),scanning electron microscopy(SEM),Brunauer-Emmett-Teller(BET)method,X-ray photoelectron spectroscopy(XPS),and ultraviolet-visible(UV-Vis)spectroscopy.The results show that Ce/Fe photocatalyst possesses a large specific surface area,good visible light response,abundant oxygen vacancies and excellent redox performance,exhibiting good adsorption capacity,remarkable catalytic performance and stability.The optimal conditions for tetracycline removal were explored through orthogonal experiments.About 88%of tetracycline can be photodegraded in 1 h under optimal conditions.The possible decomposition pathways,main reactive oxygen species and suitable mechanism of the photocatalytic system were studied by liquid chromatography-mass spectro metry(LC-MS),an electron spin resonance(ESR)spectrometer and free radical quenching experiments.The results show that 1CCFO has an efficient degradation effect on tetracycline under visible light,which provides a feasible method to improve the performance of 1CCFO.

Objective With the development of analytic technologies, in-situ dating on U-bearing oxide minerals （e.g., cassiterite, rutile and baddeleyite） has been widely used in geological chronological researches and has attracted remarkable attention to explore evolution of the earth and obtain age information of various geological processes. Matrix effect related studies are especially important during in-situ U- Pb dating based on Laser Ablation Multiple Collector Inductively Coupled Plasma Mass Spectrometry （LA-MC- ICPMS）. However, to our knowledge, only few thorough and systematical matrix effect study of U-bearing oxide minerals has been reported. In this study, we systematically analyzed the matrix effect of U-bearing oxide minerals in order to take place the standards which are difficult to prepare with available standards.

随着社交媒体的兴起,数据新闻的社交化传播问题逐渐得到重视,效果研究的重要性凸显;数据新闻属于多要素组成的复杂性对象,高热度的数据新闻拥有多种不同的内容组合形式,因此传统的定量分析具有局限性。基于此,文章以微信公众平台上的55篇数据新闻为研究对象,运用清晰集定性比较分析的研究方法,分析数据新闻高热度社交化传播的微观机制。基于“新闻本位—数据应用—可视化呈现”的主体分析框架,结合理论与案例,研究提炼新闻主题、选题性质、数据类型、数据来源、数据叙事、数据处理程度、可视化类型以及可视化形式丰富度八个内容层面的条件变量。通过清晰集定性比较分析,发现了三条典型的微观内容组态,将之归纳为专业分析型、信息描述型以及事件汇总型,并通过对微观案例的阐释分析了条件变量间联动效应的发生机制。将微观案例阐释归纳并回归理论的主体框架,得出如下结论:话题型数据新闻达到高热度传播需要具备良好的数据专业化水平;权威来源数据适用于事件汇总型新闻,而非权威来源数据适用于信息描述型新闻;动态交互图表适用于严肃议题的硬新闻。本研究在应用层面对数据新闻实践具有指导性意义,在理论层面证明了数据新闻社交化传播具有复杂性,并对其传播逻辑进行了初步探索。

近二十年来,Lu-Hf同位素分析技术得到了快速发展,为探讨岩石成因、物质来源及壳幔演化过程提供了重要手段。其中,锆石微区原位Hf同位素测定方法已经被广泛应用于同位素地球化学研究中。然而,金红石、锡石和铌铁矿等氧化物型含铀矿物激光剥蚀多接收等离子体质谱(LA-MC-ICPMS)Hf同位素测定方法发展较为缓慢。本文结合近年来相关研究工作,简要介绍副矿物Lu-Hf同位素分析技术的发展历史,系统梳理了金红石、锡石和铌铁矿等氧化物型含铀矿物原位Hf同位素测定方法研究的最新进展以及存在的问题。基于该方法目前存在的同质异位数干扰校正策略、质量监控标样的缺乏以及较低的Hf含量如何提高分析灵敏度等技术难点进行了详细论述。氧化物型含铀矿物的Hf含量普遍不高,在测试时需要更大的剥蚀束斑直径。而飞秒激光具有剥蚀的样品粒径细小且均匀的特点,采用飞秒激光与LA-MC-ICPMS(fs-LA-MC-ICPMS)相结合,可以减小剥蚀束斑从而提高原位分析的空间分辨率,是未来氧化物型含铀矿物原位Hf同位素分析的发展方向。

微束分析技术能够在微米-纳米尺度上精确分析矿石矿物的物相、形貌、结构、成分以及同位素组成,为地球科学精细研究提供重要技术支撑。本文利用多种微束分析技术的自身优势,综合运用微区X射线荧光光谱(micro-XRF)、偏光显微镜、电子探针(EPMA)以及激光剥蚀电感耦合等离子体质谱(LA-ICP-MS)分析技术,建立了一种简单直观且全面快速鉴别钴赋存状态的技术方法。首先采用偏光显微镜选出部分代表性的探针片,然后进行微区X射线荧光光谱面扫描,获得探针片中钴及组合元素分布规律及特征,再利用偏光显微镜细致观察鉴别,结合元素分布特征规律识别出独立钴矿物以及含钴矿物,最后圈出代表性矿物并采用电子探针和LA-ICP-MS进行主微量化学成分测定。将该方法应用于中非铜钴成矿带上典型铜钴矿床中钴的赋存状态研究,查明了谦比希东南矿体中的钴主要以独立矿物(钴镍黄铁矿、硫钴矿、硫铜钴矿)和类质同象(主要赋存于黄铁矿、磁黄铁矿中)两种形式存在,而谦比希西矿体中的钴主要以独立矿物——硫铜钴矿的形式零星存在。
