Self-Cleaning/Non-Wetting Coating for Corrosion Protection of Metallic Structures
This invention is a novel two-step electrodeposition technique to fabricate superhydrophobic metallic coatings. The method has been demonstrated with a superhydrophobic copper coating with multiscale surface features. A thermodynamic model has been developed which supports extending this invention to other metals.

Increased Control Over Additive Manufacturing of
Functional Emulsions
THE CHALLENGE
Functional emulsions are an emerging material architecture that can be cured into an elastomer composite with embedded liquid phase fillers. Techniques to control local composite microstructures and material composition in emulsions, which ultimately govern material properties and performance of the cured elastomer composite, are lacking.

Thermal Control During Additive Manufacturing
THE CHALLENGE
Additive manufacturing (AM) has emerged as a powerful tool within engineering. Many AM and coating processes rely on thermal input to soften or melt the materials involved in processing. However, this melting or softening typically results in a higher thermal gradient between deposited material and the workpiece, commonly resulting in...
