Completed TRL 2 (started at 2, targeting 2)
Evaporative Vapor Deposition: Here a container of a source oxide to be deposited on a substrate is heated to a high temperature. The substrate is placed in a region of cooler temperatures. It is necessary to know the vapor pressure generated by the source oxide, which is calculated via tabulated thermodynamic vapor pressures and vaporization coefficients. Durability of Ceramics at High Temperatures: Often the limiting factor in applying ceramics at very high temperatures is their vaporization characteristics. Accurate lifetime modeling requires tabulated thermodynamic data and vaporization coefficients. Fundamental Vaporization Studies and Theoretical Models: According to the terrace-ledge-kink (TLK) theory of vaporization, the molecules form an adsorbed layer before leading the solid surface. The vaporization coefficient is indicative of kinetic barriers to the formation of this layer and subsequent desorption. Such information will be useful to molecular dynamics models of vaporization.
Listed on TechPort itself — the most direct way to ask about this specific project.
This is early/mid-stage (TRL 2) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.
None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
