MIT engineers build advanced microprocessors from carbon nanotubes. The new approach uses the same manufacturing processes as silicon chips and offers decisive advances in the development of next-generation computers. After years of overcoming numerous design and manufacturing challenges, MIT researchers have developed a modern microprocessor made from carbon nanotube transistors that is widely recognized as a faster, more environmentally friendly alternative to their [...]
Summary: In this study, a method for radial induction crystallization purification for the production of 6N, 7N seed crystals with ultra-high purity was presented. The influence of the cooling temperature on the morphology of the seed crystal as well as the cooling water temperature, the flow rate and the amount of seed added on the crystallization process were investigated, and the best cleaning process parameters were obtained as follows: temperature of the [...]
