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

Microstructure-Property Tools for Structure-Property Design

Ongoing
Microstructure-level Structure-Property Tools OOF: Finite Element Analysis of Microstructures enables materials scientists calculate macroscopic properties from images of real or simulated microstructures. It reads an image, assigns material properties to features in the image, and conducts virtual

NCNR DAC and CCUS efforts

Ongoing
Objectives To advance US competitiveness in Direct Air Capture (DAC) and Carbon Capture, Usage, and Sequestration (CCUS) Use advanced neutron scattering techniques to understand the adsorption process for the most promising materials for adsorption-based carbon capture and provide avenues to
