Carbon Dioxide Removal via Passive Thermal Approaches

A regenerable approach to separate carbon dioxide from other cabin gases by means of cooling until the carbon dioxide forms carbon dioxide ice on the walls of the physical device has been developed. Currently, NASA space vehicles remove carbon dioxide by reaction with lithium hydroxide (LiOH) or by adsorption to an amine, a zeolite, or other sorbent.

Polymer Electrolyte-Based Ambient Temperature Oxygen Microsensors for Environmental Monitoring

An ambient temperature oxygen microsensor, based on a Nafion polymer electrolyte, has been developed. A challenge in the operation of Nafion-based sensor systems is that the conductivity of Nafion film depends on the humidity in the film. Nafion film loses conductivity when the moisture content in the film is too low, which can affect sensor operation.

Capturing and Using Waste Heat from Cars, Factories, and Power Plants

New technology is being developed at Oregon State University to capture and use the low-to-medium grade waste heat from automobiles, diesel generators, or factories and electrical utilities. The new systems should be able to use much of that waste heat either in cooling or the production of electricity.
