Abstract: A time-temperature indicator (TTI) uses polymer hardening properties to “set” or retain indications of temperature history. The TTI includes a mesh layer affixed to a thermo-conductive adhesive layer and a photonic crystal patterned film affixed to the mesh layer. The photonic crystal shows a property of bandgap shift vs temperature and responds to a predetermined range of temperatures to provide a visible indication of the range of temperatures. A hardener pouch is affixed to one end of the mesh layer and releases hardener in response to an initiating event, so that the photonic crystal material responds to the hardener by presenting a fixed state.

Abstract: A self-regenerating chitosan based filter medium for disinfecting and purifying organic pollutants and other pollutants in a gas or liquid is disclosed herein. Porosity and surface charge of said filter medium is manipulative/tunable by varying one or more of the following parameter(s): concentration of chitosan, crosslinking density, amount of copolymers and additives, freezing temperature, freezing profile, and/or types of crosslinker used. The present filter medium is capable of self-regenerating under exposure to ultra-violet light for sufficient time and removing over 90% of the pollutants from each influent flowing through the filter medium.
