Mannitol for High Temperature Phase Change Actuators

open access: yes, 2014
To enable valves for hot water microsystems, the possibility of using the volume expansion of the phase transition from solid to liquid in mannitol for strong high temperature actuators was studied. From room temperature to 160°C, a linear expansion of 4% was measured, and the expansion at the phase transition from solid to liquid at 160°C to 180°C was

Phase Change Temperature Sensor for High Radiation Environment

open access: yes, 2021
Performance of any sensor in a nuclear reactor involves reliable operation under a harsh environment (i.e., high temperature, neutron irradiation, and a high dose of ionizing radiation). In this environment, accurate and continuous monitoring of temperature is critical for the reactor's stability and proper functionality.
