PPT-Carbon Nanotubes as a Heating Agent in Microwave Ablation

Introduction Microwave Ablation MWA is a technique for ablating tumors using microwave frequency electromagnetic energy to heat the tissue to temperature to 60 degrees Celsius at which point cell death occurs In this technique microwave power is transmitted from a generator through a transmission line to an antenna inserted into the tumor subcutaneously where it is radiated as electromagnetic wave into tissue Although MWA has been successfully completed in human clinical trials there is room for improvement in the necessary duration and required power level used for the procedure. brPage 1br Microwave Ablation System D57693576165774057725d57690576305774057717y5827257347D576935761657740577255779357602577925763057347 Carbon Nanotubes and Their ApplicationsEdited by Qing ZhangCopyright Science Discussion Group. “.

Carbon . nanotubes. are small tubes of carbon fiber that are prized for their electrical, mechanical and thermal properties making them ideal for a variety of applications. CNTs small size and thermal properties make them ideal for future transistor and interconnect production providing a solution to the problem of Moore’s Law. In addition, CNT’s mechanical properties can be tied in with their electrical properties to produce a variety of sensors and related devices..

Carbon is the 6. th. most abundant element in the universe and is estimated to be involved in some way in almost 95% of known compounds. Carbon is capable of bonding with up to 4 other atoms at a time, including other carbon .

A superconductor can transport an enormous amount of current flow at tiny voltages. At present, known superconductors work at very low temperatures. This field of research is very important since if a material were super­conductive at room temperature, it would carry current with no resistance.
