Multifunctional AM Project Page

Multifunctional 3D Printable Polymer-Metal Composites

Ongoing
Recent advances in additive manufacturing (AM) have positioned metals and polymers as two key materials. Typically, AM of these two materials involves incompatible methods and conditions. The novel multifunctional polymer-metal composites in this project incorporate low-melting alloys with
Catalyst Testbed

X-ray Testbed for Breakthrough Catalyst Measurements

Ongoing
Interested in collaborating? See below What does this project do for industry? Current measurement techniques are unable to follow the reaction pathways during catalysis and are limited to observing only the end products or looking at catalysts outside of realistic reaction conditions. Our new
