Recent studies have shown that inactivation of the tumour suppressor gene VHL located in chromosome 3p25-26 region is responsible for sporadic RCCs. According to Kundson＇s two hit theory, the mechanism of inactivation of a tumour suppressor gene involves mutation, hypermethylation and loss of heterozygosity （LOH）.展开更多

文摘采用Li_2CO_3与Li OH·H_2O为复合锂源制备LiFePO_4/C材料,同时优化了材料中的碳含量。由于氢氧化锂的熔点低于碳酸锂,在同样的烧结温度下,采用复合锂源可以获得更佳的熔融状态,在高温合成过程中使锂离子具有更高的扩散性,能够更顺利地得到高纯度的LiFePO_4晶相。通过优化碳包覆量达到提高导电性与控制晶粒尺寸的目的,使材料晶相结构完整,纯度高,表现出优秀的加工性能与电化学性能。所制得的LiFePO_4/C材料放电克容量达到158.2 m Ah·g^(-1),在全电池中经过100 d存储后容量保持率仍然高于94.0%,具有优异的长期可靠性。
