Abstract: One promising thermochemical reaction for energy storage is the hydration of hygroscopic salts. However, pure salts have poor cycle stability. The present work investigates a new composite material by impregnating a framework ...

Abstract: Phase change thermotropic materials have been proposed as a low cost method to provide passive overheat protection for polymer solar thermal absorbers. One challenge to their development is control of the size of the phase ...

Abstract: In recent years, some streams and fisheries have been experiencing higher surface water temperatures, which negatively impact cold-water trout species. One potential solution is to provide localized refugia of colder water ...

Abstract: A waste heat assessment of a manufacturing facility was conducted. A physical survey identified potential waste heat sources. For these sources, the temporal fluctuations in temperature and flowrate, and the frequency of ...

Abstract: A Monte Carlo model is applied to determinate the steady state, solarweighted optical properties of potential thermotropic composite materials for overheat protection of polymer solar absorbers. The key results are ...

Abstract: Solar hot water and space heating systems constructed of commodity polymers have the potential to reduce the initial cost of solar thermal systems. However, a polymer absorber must be prevented from exceeding its maximum ...

Abstract: The present work describes the design of a device/system intended to induce local mild hypothermia by simultaneously cooling a patient's head and neck. The therapeutic goal is to lower the head and neck temperatures to ...

Abstract: A prototype 4 kW solar thermochemical reactor for the continuous splitting of carbon dioxide via the isothermal ceria redox cycle is demonstrated. These first tests of the new reactor showcase both the innovation of ...
