A passive carrier employing water-based phase-change materials is designed to return temperature-critical payloads from the International Space Station. These materials expand by 9% when frozen, which can cause rupture of freezers and/or an inability

We describe a methodology for determining thermal diffusivities in real time by using temperature measurements at only two locations in a cylindrical sample. The technique is based on an analytical solution of heat transfer in a circular cylinder. Th

Vacuum insulation panels have values of thermal conductivity that are extremely low ∼4mW/ms˙K compared to the thermal conductivity of most common insulations. Typical ASTM test methods are not designed for testing these very low thermal conductivi

Polyurethane foam has been produced in low gravity for the first time. The cause and distribution of different void or pore sizes are elucidated from direct comparison of unit-gravity and low-gravity samples. Low gravity is found to increase the pore
