Abstract: A process for producing spherical activated carbon is complex; therefore, an adsorbent that has an effective adsorption amount larger than or equal to that of spherical activated carbon and that is easily produced is desired. An adsorption heat pump uses, as refrigerant, carbon dioxide and uses, as an adsorbent, a metal-organic framework including a metal ion and an organic ligand. The metal-organic framework is, for example, MOF-200.

Abstract: A cooling shirt is disclosed. The shirt is formed from a resilient fabric comprised of a first yarn of a first material and a second yarn of a second material twisted and knitted together. In one embodiment, the first yarn is formed from fibers have surfaces adapted to channel liquid from wet areas to dry areas and the yarn has pores adapted to permit evaporation of liquid vapor therethrough, and the second yarn is resilient and capable of being stretched at least 300% without deforming. The first yarn constitutes between 85% and 95% of the weight of the fabric with the second yarn constituting the remainder. In one embodiment the resilient fabric is capable of being resiliently stretched at least 40% in each of two perpendicular directions without tearing and returning immediately to its at-rest position. In one embodiment, the first yarn has a porosity of between approximately 20% and 45%.
