    Abstract: Storage systems based on latent heat storage have high-energy storage density, which reduces the footprint of the system and the cost. However, phase change materials (PCMs), such as NaNO3, NaCl, KNO3, have very low thermal conductivities. To enhave the storage of PCMs, macroencapsulation of PCMs was performed using a metal oxide, such as SiO2 or a graphene-SiO2, over polyimide-coated or nickel-embedded, polyimide-coated pellets The macro encapsulation provides a self-supporting structure, enhances the heat transfer rate, and provides a cost effective and reliable solution for thermal energy storage for use in solar thermal power plants. NaNO3 was selected for thermal storage in a temperature range of 300° C. to 500° C. The PCM was encapsulated in a metal oxide cell using self-assembly reactions, hydrolysis, and simultaneous chemical oxidation at various temperatures.

  • Patent number: 9309449
    Abstract: The present disclosure relates generally to deicer compositions comprising a liquid deicing agent which is as an aqueous solution of a deicing salt and additives that provide reduced corrosiveness with reduced biochemical oxygen demand. Aspects of the disclosure are particularly directed to use of the deicer composition as a liquid deicer or an anti-icer. The deicer composition can further include a solid deicing agent such as sodium chloride, where the liquid deicing agent and additive form a pre-wetting agent when mixed with the solid deicing agent to form a pre-wetted deicer.

  • Patent number: 9279075
    Abstract: The present invention provides methods of producing manufactured aggregates and other compositions from an encapsulated PCM slurry, suspension or emulsion by combining a cementitious binder and a adsorbent and/or absorbent with the PCM slurry. The encapsulated PCM-containing composition can be produced in an agglomeration process. The ingredients can also be mixed to form a viscous mass which can be extruded or otherwise formed to produce useful products.

  • Patent number: 9120945
    Abstract: A method is described for the production of a dispersion, especially a coating or sealing compound, having a viscosity of less than about 30,000 mPas, whose viscosity increases to more than 50,000 mPas or that becomes firm as a result of its application, whereby a shear-thickening additive is added to a precursor composition of the dispersion at a shear rate that does not activate the shear-thickening additive. Consequently, it is possible to formulate dispersions, especially sealing and/or coating compounds, in such a way that they have a low viscosity for storage and processing, and only at the time of the use of the dispersion is the final viscosity set by suitable equipment.
