Chloride solid electrolytes(SEs)have attracted widespread attention due to their high room-temperature ionic conductivity and excellent cathode ***,the conventionally selected central metal elements(e.g.,In,Y and Ta)are usually rare and heavy,inevitably causing the high cost and high density of the obtained chloride ***,by choosing abundant and light Mg and Al as central metal elements,we develop a cheap and low density Li_(1.2)Mg_(0.95)Al_(0.3)Cl_(4)SE for high active material ratio in all solid state *** replacement of Mg^(2+)by Al^(3+)in the framework yields vacancies and lowers the non-lithium metal ions occupancy at Mg/Li co-occupied 16d site,effectively relieving the blocking effects by Mg^(2+)in the pristine spinel Li_(2-2x)Mg_(1+x)Cl_(4).Thus,a significantly improved room-temperature conductivity of 3.08×10^(-4)S·cm^(-1)is achieved,two orders of magnitude higher than that of Li_(1.2)Mg_(1.4)Cl_(4).More attractively,its low density of only 1.98 g·cm-3 enables low SE mass ratio in cathodes(only 16 wt.%)with still effective electrolyte/cathode contact and lithium-ion conduction *** charged to potential of 4.30 V,the asfabricated Li_(1.2)Mg_(0.95)Al_(0.3)Cl_(4)-based solid lithium battery with uncoated NCM523 cathode can be cycled for over 100 cycles with a capacity retention of 86.68%at room temperature.

细根是植物在生长发育过程中吸收与运输养分的重要器官,研究不同菌根类型植物幼苗细根功能性状之间的变异与权衡有利于更全面地理解植物早期的生存策略。该研究以黑龙江凉水国家级自然保护区阔叶红松(Pinuskoraiensis)林内3种丛枝菌根(AM)和3种外生菌根(EM)树种幼苗为研究对象,通过测定其细根的3个形态性状:比根长(SRL)、根组织密度(RTD)、根直径(D)与4个化学性状:全磷(P)含量、全碳(C)含量、全氮(N)含量、碳氮比(C:N),分析了细根性状在不同菌根类型间、根级间以及根功能模块间的差异及其权衡。结果表明,与AM幼苗相比,EM幼苗细根具有更大的RTD,这是由于AM真菌的定植方式会增大细根的体积,同时提高AM菌根对限制性养分的吸收能力,而其余性状在两种菌根间无显著差异;AM幼苗细根整体符合资源获取型策略,而EM则相反;随着根级增加,两种菌根幼苗细根的RTD、D均显著增加,SRL则显著减小,细根的功能从主要负责吸收转变为主要负责运输,细根的C含量、C:N随之上升,N含量下降;细根的形态特征与化学计量特征间存在权衡关系,即根功能模块随根级变化时,细根的形态性状与化学性状也产生相应改变,研究结果支持根经济谱假说。

为了提高1,1‐二氨基‐2,2‐二硝基乙烯(FOX‐7)的热分解特性,在较低分解活化能下实现能量的快速释放,采用溶剂‐反溶剂的方法制备了掺杂改性的FOX‐7/MoS2含能复合材料。采用扫描电子显微镜(SEM)、能谱仪(EDS)、X射线粉末衍射(XRD)、X射线光电子能谱(XPS)、热重‐差示扫描量热仪(TG‐DSC)等分析测试手段对复合材料的形貌结构、物相组成、热分解特性、分解活化能进行了表征和测试。结果表明,掺杂改性的FOX‐7/MoS2含能复合材料既可以提高低温阶段的分解温度,又可以催化高温下的分解放热。其中,与原料相比,FOX‐7/MoS2‐5%的低温阶段的分解温度和分解活化能分别提高了6.8℃和78.6 kJ·mol^(-1);高温阶段的分解温度和分解活化能分别降低了23.4℃和340.4 kJ·mol^(-1)。热重‐质谱结果表明,高温阶段FOX‐7/MoS2‐5%产物中CO_(2)的比例从7.3%增加到16.8%,表明MoS_(2)的掺杂改性又促进了高温阶段的分解,使分解更加完全和充分。

蛇纹石是中国最早使用的玉石之一,开展蛇纹石玉的产地溯源探索,对认识中国古代玉文化发展历程,重建古代玉石贸易路线均有重要的意义。但由于蛇纹石玉产地众多,目前尚没有成熟的蛇纹石玉产地溯源的判别技术。以产自陕西汉中、甘肃敦煌、河南栾川、辽宁岫岩、山东泰安、甘肃武山6地的蛇纹石玉为研究对象,在66块样品上共采集到200个高质量拉曼光谱数据,并在对测试结果进行主成分分析(PCA)的基础上建立了线性判别分析(LDA)的产地判别模型。结果显示,不同产地蛇纹石玉的矿物组成有所差异,汉中蛇纹石玉的主要矿物成分有纤蛇纹石和利蛇纹石两种;敦煌蛇纹石玉则为纤蛇纹石和利蛇纹石的均匀混合型;泰安蛇纹石玉的主要矿物成分有利蛇纹石(墨玉)和叶蛇纹石(碧玉和翠斑玉)两种;河南栾川、辽宁岫岩、甘肃武山蛇纹石玉的主要矿物成分均为叶蛇纹石。在严格控制实验条件的前提下,将拉曼光谱数据结合PCA+LDA分析可以对不同产地的蛇纹石玉进行区分,所建立的LDA判别模型的训练集数据和测试集数据的产地判别正确率分别达到了96.25%和92.50%。这显示出利用无损检测拉曼光谱技术进行蛇纹石玉产地溯源具有潜在价值。将拉曼光谱无损检测数据结合统计学或机器学习方法来构建判别模型可能是解决蛇纹石玉产地溯源瓶颈新的技术路径。

OBJECTIVE: To investigate the mechanisms of the effect of Actinidia chinensis polysaccharide(ACPS) on the invasion and metastasis of gastric cancer ***: BGC-823-Luc gastric cancer cells stably transfected with a luciferase gene were used to establish an insitutransplanted tumor mouse model. A live mouse imaging system was used to observe tumor growth, and hematoxylin and eosin staining was applied to analyze tissue histopathology. Transwell and scratch wound assays were performed to examine the invasive and migratory ability of BGC-823 cells. Immunofluorescence,confocal microscopy, immunohistochemistry, and Western blot assays were used to analyze the expressions of the nuclear transcription factor-κB(NF-κB)signaling pathway and epithelial-mesenchymal transition(EMT)-related ***: ACPS significantly inhibited the growth of subcutaneously transplanted BGC-823-Luc gastric cancer tumors in nude mice and reduced inflammatory cell infiltration in tumor tissues. ACPS inhibited Epidermal Growth Factor-induced invasion, migration, and morphological changes in the cytoskeleton of BGC-823cells. ACPS inhibited gastric cancer EMT and decreased the expression of matrix metallopeptidase 9, N-cadherin and p-NF-κB p65 in transplanted tumor tissues. ACPS inhibited the expression of matrix metalloproteinases and vascular adhesion factors in BGC-823 cells, promoted p65-NF-κB nuclear translocation, and regulated proteins associated with the NF-κB p65 ***: ACPS inhibited gastric cancer invasion and metastasis both in vivo and in vitro, which evidenced the inhibition of gastric cancer EMT via regulating the NF-κB inflammatory pathway.
