The development of zinc-ion batteries with high energy density remains a great challenge due to the uncontrollable dendrite growth on their zinc metal *** anodes plated on the substrate have attracted increasing attention to alleviate these dendrite ***,we first point out that both the random crystal orientation and the low metal affinity of the substrate are important factors of zinc dendrite ***,the(1 O 1)fully preferred tin interface layer with high zinc affinity was fabricated by chemical tin plating on(1 O o)oriented *** tin decorated copper substrate can realize high reversible zinc plating/stripping behavior,and full cell using this zinc plated substrate can be operated for more than 1000 cycles with high capacity retention(85.3%)and low electrochemical *** proposed strategy can be also applied to lithium metal batteries,which demonstrates that the substrate orientation regulation and metal affinity design are the promising approaches to achieve dendrite-free metal anode and overcome the challenges of highly reactive metal anodes.

ABM: To investigate the cytotoxicity of the cytokine-induced killer (CIK) cells from the post-operation patients with primary hepatocellular carcinoma (HCC) to multidrug-resistant (MDR) cell of HCC both in vitro and in vivo. METHODS: A drug-resistant cell line was established by culturing human HCC cell line Bel-7402 in complete RPMI 1640 medium with increasing concentrations of adriamycin from 10 to 2 000 nmol/L. CIK cells were obtained by inducing the peripheral blood mononuclear cells with rhlFN-γ, monoclonal anti-CD3 antibody, rhIL-1α as well as rhIL-2, which were added into the culture. To detect the cytotoxicity of the CIK cells from HCC patients, the Bel-7402/R was taken as target (T) cells and CIK cells as effect (E) cells. Cytotoxic test was performed and measured by MTT. As to in vivo test, CIK cells were transfused into patients with HCC. The tumor specimens of the patients were obtained and immunohistochemistry was carried out to detect CD3, CD45, CD45RO as well as CD68. RESULTS: A MDR 1 HCC cell line Bel-7402/R was established. Its MDR1 mRNA overexpressed which was shown by RT-PCR; the P-glycoprotein expression increased from 1.32% of parent cells to 54%. CIK cells expanded vigorously by more than 70-fold and the CD3+CD56+ increased by more than 600-fold after 3-wk incubation on average. The cytotoxicity of CIK from HCC patients to Bel-7402/R was about 50% and to L-02 below 10% (t = 8.87, Pliver cancer tissue and CD3, CD45, CD45RO, and CD68 increased greatly which was shown by immunohistochemistry. CONCLUSION: A stable MDR1 HCC cell line has been established which could recover from liquid nitrogen and CIK from HCC patients has strong cytotoxicity to MDR HCC cell. CIK adoptive immunotherapy is safe

Due to the unsatisfactory electrode/electrolyte interface,the metallic Zn dendrites and corrosion are easily induced,severely hindering the applications of zinc-ion batteries(ZIBs).Herein,a strategy that engineers the interfacial double layer by an extremely low concentration of sulfolane is proposed to tune the Zn stripping/plating *** is revealed that the highly-polar sulfolane can predominately occupy the inner Helmholtz layer over water,and then regulate the upcoming Zn2+to directly deposit ***,the widened Helmholtz layer can weaken the electric field intensity,which will generate more nucleation sites and reduce the nuclei radius,thereby promoting uniform zinc deposition as ***,corrosion byproducts can be inhibited since fewer water molecules can contact the Zn ***,the battery performance can be naturally *** an optimum amount of sulfolane,the Zn||Zn battery can operate for more than 1,100 h under1 m A cm^(-2)and 1 m Ah cm^(-2).And the as-constructed Zn||NaV_(3)O_(8)·1.5H_(2)O battery demonstrates considerably higher cycling stability than that without ***,this work has provided a deep insight into constructing a functional interfacial double layer to regulate zinc deposition,which can also act as a reference for other metal-based batteries.

Military transparency is a complicated the Sino-U. S. relations and also a degree of their interest coincidence. and sensitive issue in touchstone testing the One can hardly gain a full and profound insight into the essential implication of military transparency if he is dominated by the realist logic and putting undue emphasis on the importance of it in the bilateral military relation. Given the fact that China and the United States are two important powers shouldering critical responsibilities for maintaining global peace and security, this article argues that only by adopting a new security concept toward military transparency could the two countries forge a consensus on the international security situation and remove misunderstanding, misgivings and distrust in their military contacts and cooperation. Only by actively seeking and constructing a new security regime could the two sides strengthen the institutional base for their military cooperation.

近来,陆权、海权问题及中国的战略取向已成为广大学者及社会各界广泛关注的热点。本刊2007年第6期刊登了北京大学叶自成教授《从大历史观看地缘政治》一文,该文认为海上力量"聚集得快,消失也快",陆权发展的成果"更能长期支撑一个国家的发展和地位",更具持久性。他主张每个国家应当根据自己的自然禀赋来选择海权与陆权的孰先孰后,并强调制度建设是一国发展陆权或海权的重要内涵。叶文发表后,不少学者纷纷来稿阐述自己的看法。本刊本期刊登李义虎教授的《从海陆二分到海陆统筹——对中国海陆关系的再审视》一文,以飨读者。李义虎教授提出,中国是一个海陆度值高、兼具陆地大国和濒海大国双重身份的地缘实体,在战略上需要消解海陆二分的现实,而采取海陆统筹的全方位选择。本刊将陆续刊登围绕这些问题而展开的讨论文章,并热诚期待有更多学者踊跃来稿。

拜登政府实行什么样的对华政策及对台政策,是海峡两岸和国际极为关注的问题。对拜登对华政策与对台政策的研判应集中在"战略定位"和"战略竞争"两大方面,而非仅孤立关注"战略竞争";对这两大方面的把握,需要放在一个合理的分析框架中加以说明,即:要弄清"战略竞争"的性质和特点,必须首先弄清拜登对中国所做的"战略定位",因为"战略定位"决定"战略竞争";正是在对华定位为"战略竞争对手"的前提下,拜登政府要与中国"高强度的战略竞争"或"最严峻的战略竞争"。同时也要区别"战略竞争"在拜登语境下与在特朗普语境下究竟有何异同。而研判美国对台政策,首先需要弄清美国对华政策,中美关系大框架仍然是制约、甚至决定美台关系的基础和前提。
