USF inventors have developed self-heating and cooling, layered assembly systems that allow for rapid heat-up times on the order of a few minutes that also last several hours at near-constant tunable temperatures. More specifically, this invention provides customizable time-temperature profiles through chemical transformations for rapid and extended-release of a wide range of low volatility matter. This invention can be applied to enhance release profiles of beneficial active components such as medication, insect repellants, and scents, etc.
