The formation of stable and densely networked structures and the synergy between NRGO and alpha-MnO2 nanowires enable the alpha-MnO2/NRGO film electrode to show a large area-specific capacitance (386.8 mF cm(-2)) at 1 mA.cm(-2) current density; the capacity retention is 62.4% when the ...
Single-crystal alpha-MnO2 nanorods were grown on multi-walled carbon nanotubes (MWNTs) in H2SO4 aqueous solution. The morphology and microstructure of the composites were examined by transmission electron microscopy, high-resolution transmission electron microscopy (HRTEM), X-ray diffractometry and energ...

程序Heap内存区域有执行权限,并且Add功能存在下标溢出。当使用负数下标时可以覆盖got表项指针指向堆内存,从而执行自定义shellcode。但是堆块输入限制非常大,只有8个字节,而且要求全为大小写字母或数字。也就是说需要用多个堆块借助拼接构造shellcode。 为了简化利用,先构造调用SYS_read的shellcoed,然后借助它往堆上读执...
Although the production of CDs has moved away from the earlier use of bacteria in favor of CGTase, in later times a Bacillus firmus strain, immobilized on inorganic matrices (preferably SiO2/TiO2 and SiO2/MnO2) has been proposed3232 for the production of CDs. ...
