Owing to the unique structure,anode-free lithium metal batteries(AFLMBs)have higher energy density and lower production cost than traditional lithium metal batteries(LMBs)or lithium-ion batteries(LIBs),However,AFLMBs suffer from an inherently finite Li reservoir and exhibit poor cycle stability,low Coulombic efficiency(CE)and severe dendrite *** this work,polydiallyl lithium disulfide(PDS-Li)was successfully synthesized and coated on Cu current collector by electrochemical *** PDS-Li acts as an additional lithium resource to compensate for the irreversible loss of lithium during *** addition,the special structure and lithiophilicity of PDS-Li contribute to lower nucleation overpotential and uniform lithium *** coupled with Li-rich manganese-based(LRM)cathode of Li1.2Mn0.54Ni0.13Co0.13O2,the anode-free full cell exhibits significantly improved cycle stability over 100 cycles and capacity retention of 63.3%and 57%after 80 and 100 cycles,*** believe that PDS-Li can be used to ensure stable cycling performance and high-energy-density in AFLMBs.

Identification of Differentially Expressed Genes in the Salivary Gand of Rhipicephalus haemaphysaloides by the Suppression Subtractive Hybridization Approach

引用

Journal of Integrative Agriculture 2012年第9期11卷 1528-1544页

作者： XIANG Fei-yu zhou Yong-zhi zhou jin-lin Key Laboratory of Animal Parasitology Ministry of Agriculture~Shanghai Veterinary Research Institute Chinese Academy of AgriculturalSciences Shanghai 200241 P.R.China

For the purpose of screening and analyzing the differentially expressed genes from the salivary gland of Rhipicephalus haemaphysaloides, two salivary gland-subtracted cDNA libraries of partially fed female ticks and fed male ticks were constructed using suppression subtractive hybridization （SSH）. A total of 247 female expression sequence tags （ESTs） and 168 male ESTs were obtained from the two SSH cDNA libraries. It is predicted that 25 female ESTs and 44 female ESTs contain the 5＂ and 3＂ ends, respectively, and that 53 male ESTs and 74 male ESTs contain the 5＂ and 3＂ ends, respectively. To identify the subtraction rate of the two SSH cDNA libraries, the RT-PCR method was used to test 24 female ESTs and 21 male ESTs selected randomly but not repeatedly. The results showed that there were 13 upregulated or differentially expressed genes in the partially fed salivary gland of the female R. haemaphysaloides and that the differentially expressed rate was 54%. In addition, they indicated that there were 9 upregulated or differently expressed genes in the fed salivary gland of the male R. haemaphysaloides and that the differentially expressed rate was 43%. Putative translations of 141 （57%） female ESTs and 125 （74%） male ESTs had similarity to GenBank sequences, and 32 （23%） female ESTs and 29 （23%） male ESTs exhibited similarity to tick proteins, which showed that most of the proteins in the libraries were mainly related to the feeding blood physiology of the ticks.
