Patent number: 9976068Abstract: The chemical reactions modulation of temperature and dissipate heat through using phase change materials (PCM). Hydration of a mixture composed of encapsulated and/or non-encapsulated oxides such as calcium oxide and/or magnesium oxide and dehydrated and/or hydrated zeolite coupled with control of pH of mixture through compounds such as Citric acid, or combination exothermic mixes, such as Cao and Mg—Fe, provide sustained heat release and heat retention tailored by addition of PCMs. The modulation may include timed/controlled release from encapsulated reactants and may include particles with tailored size distribution and different burn characteristics. The phase change materials used include organics (paraffins, non paraffins and fatty acids) and inorganics (salt hydrates). The selection of PCM is based on compatibility with the reacting mix, added reacting aqueous medium, and the desired temperature the system is to be held constant or temperature range it is desired to be modulated.Type: GrantFiled: June 30, 2016Date of Patent: May 22, 2018Assignee: University of South FloridaInventors: Sermin G. Sunol, Aydin K. Sunol

Patent number: 9863687Abstract: Self-heating apparatus and methodology for customizing a time-temperature profile thereof. The layered apparatus includes at least a layer of phase change material and a layer of air- or oxygen-activated material. When the air- or oxygen-activated material is activated, heat is released rapidly and is absorbed by the phase change material. The phase change material then releases the absorbed heat over a long period of time. Time-temperature profiles can be adjusted based on type, amount, and configuration of phase change and air-activated materials used. The apparatus and methodology allows rapid heat-up of times of a few minutes and lasts several hours at near constant tunable temperatures.Type: GrantFiled: August 14, 2015Date of Patent: January 9, 2018Assignee: University of South FloridaInventors: Aydin K. Sunol, Sermin G. Sunol, Emilee Chassanne Bannister, Pamela Alvarez Moreno, Kyle Louis Cogswell

Patent number: 8863737Abstract: Exothermic reactions are used in self heating products, such as food, beverages, and clothing. Temperature peaks are important as heat can cause user injuries or increase pressures within the heating container to unsafe levels. Disclosed is a composition that modulates chemical reactions by control of the reaction initiation. Solid exothermic reactants, like calcium oxide and zeolite, are wetted with a combination of water and at least one surfactant, such as polyethylene glycol. The use of surfactants limits the initial rate of wetting, and also provides modulation of the reaction by changing phase. Optional addition of weak acids or acid salts modulated temperature and pH.Type: GrantFiled: July 7, 2011Date of Patent: October 21, 2014Assignee: University of South FloridaInventors: Sermin G. Sunol, Aydin K. Sunol

Publication number: 20090090351Abstract: A heater device that includes an outer container formed from a vapor impervious material and holds a quantity of heat generating material. A second container is positioned inside the outer container and hold an activation material. A seal on the second container is adapted to be opened to transfer the activation material into contact with the heat generating material to generate heat. The device is useful in heating food such as military field rations.Type: ApplicationFiled: July 22, 2008Publication date: April 9, 2009Inventors: Aydin K. Sunol, Sermin Sunol, Tobi W. Ferguson

Patent number: 6426116Abstract: A method for preparing coatings of thin films onto solid particle has been achieved by in-situ simultaneous nucleation and deposition of dissolved material out of supercritical fluid, resultant film formation on the solid particles suspended in the supercritical fluid, and subsequent thermal conditioning of the coating in the particles. The coating method involves an enclosed system that provides: 1) for suspension of the solid particles to be coated; 2) for dissolution of the coating material in the supercritical fluid solvent; 3) for temperature or pressure swing operations causing film deposition/coating of the suspended solid particles and; 4) additional chemical addition and/or thermal cycles providing for any additional reactions required (such as polymerization).Type: GrantFiled: October 26, 2000Date of Patent: July 30, 2002Assignee: University of South FloridaInventor: Aydin K.
