An energy-efficient method of controlling the composite microstructure and resulting thermoelectric (TE) properties of TE composite films. The TE composite films, which include a small amount of naturally occurring chitosan binder that is sufficient to hold TE particles together, are modified by applying uniaxial mechanical pressure at low temperatures for a short duration. The TE composite films have high electrical conductivity and low thermal conductivity, making them ideal for use into high-performance energy harvesting thermoelectric devices.

A chemical indicator strip for detecting disinfectant that includes a film substrate, and an indicator portion with a first and a second ink. The first and the second ink can react in the presence of a threshold level of disinfectant for a threshold level of exposure time. The chemical indicator strip can be used in a method of detecting a threshold level of disinfectant. The method can include exposing a chemical indicator strip to a concentration of disinfectant for a preset amount of time. The method can include providing a visual indicator to a user that changes from a first color to a second color. The method can indicate that the chemical indicator strip has been exposed to a threshold concentration of disinfectant for a threshold amount of time when a complete color change occurs on the chemical indicator strip from the first color to the second color.
