Low-cost and reliable methods for monitoring the size of the ablation zone during microwave thermal ablation (MTA) are crucial in the oncological clinical practice. The aim of this work is to test the performance of electrical impedance tomography (EIT) for the real-time monitoring of the ablation area where relevant temperature increases occur. In this work, two experimental studies were performed with a 16-electrode EIT system using a liver-mimicking agar phantom. First, an EIT system was tested to monitor the cooling of the phantom from an initial temperature of about 72°C.

In space environment, the surfaces of a spacecraft interact with the surrounding charged particles. Depending on the orbit, this interaction can induce a significant absolute charge on the structures and/or a differential charge collected among components. These phenomena generate electrostatic discharges with catastrophic consequences for the satellites. In this work, we investigate the volumetric electrical properties of nanocomposites made of aerospace-grade epoxy resin (RTM6) with single wall carbon nanotubes (SWCNT) as fillers to mitigate the electrostatic discharge phenomenon.
