| dc.description.abstract | When exposed to an electromagnetic field, the heat generated by CNTs is proportional to the power of the field and the concentration of CNTs exposed. Additionally, the field’s frequency, the sample geometry, heat transfer effects and functionalization of the CNTs affect the heating rate of the sample. In order to minimize these effects, we have developed a novel calorimeter system. This system consists of an insulating calorimeter vessel filled with a heat sink fluid. The sample is then placed in a thermally conductive crucible which is submerged in the fluid. The system can be closed to prevent heat loss, with a thermocouple is placed inside. The entire system is then exposed to a non-contact, RF field of constant frequency and constant power. The heat generated by the CNTs in the sample is captured in the fluid and recorded. The recorded temperature rise can then be compared against a calibration curve in order to quantify the concentration of CNTs. | en |
