چکیده
Thurid Gspann said: There appears to be a length issue when dealing with carbon nanotubes. On the one hand for most applications, mechanical as well as electrical, CNT ends represent the ultimate defect. In other words CNTs should be as long as possible. On the other hand, purication, solubilisation and separation processes either shorten CNTs or require them to be of a length usually less than 5 micron. What is the estimated maximum length of CNTs to be separated by gel electrophoresis? And do you see any possibilities of increasing this length to say 100 micron range?

متن کاملInfluential Mechanisms and Potential Applications of Nano-Silicas in Cement Composites
Nanosilicas have been known as super-pozzolanic materials and compared to silica fume, these materials have higher purity of silica and finer particles. However, in contrast to silica fume, nanosilicas are produced by various methods, leading to different morphologies and agglomeration statuses in their initial form. On the other hand, due to several mechanisms such as the bridging effect of ca...
