Hierarchical Materials

Ongoing
The STG develops the methods and metrology that will lead to the understanding of the structure-property relationships of hierarchical composites in real medical PPE or protective applications, which heretofore has been lacking. This work establishes in situ monitoring of advanced manufacturing

Metrologies for Non-linear Materials in Impact Mitigation

Ongoing
Overview This project develops fundamental structure-property measurements on model materials and novel material chemistries from quasi-static to dynamic rates. The goal is to foster a materials by design approach for novel energy dissipation and force re-direction mechanisms. Processing-Structure

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

Safety and Security Technologies

Ongoing
The safety and security of citizens is enhanced when law enforcement and criminal justice agencies and the military use the appropriate and properly performing equipment and technologies. To ensure these entities have the necessary equipment, the STG conducts and performs research to advance these

Sensing and Imaging of concealed objects

Ongoing
Threats to personal and collective safety abound in our society. The Security Technologies Group (STG) performs research to advance the technology and measurement science of security imaging and sensing. This work includes the establishment of test and evaluation tools, reference test beds, test

Structure-Property Relationships for High-Strength Materials

Ongoing
The body-armor community generally bases armor design on empirical models that do not directly relate molecular properties to performance. Aramid, aramid copolymers, and polyethylene fibers are highly oriented, anisotropic fibers that require specialized characterization techniques. In addition
Project Infographic for synthesis and longevity of candidate direct air capture (DAC) materials

Synthesis and longevity of candidate direct air capture (DAC) materials

Ongoing
We have been working on the identification and development of repeatable synthesis techniques for DAC materials for the purposes of generating repeatable samples for evaluating DAC characterization techniques. We have initially focused on impregnated and grafted aminosilane-silica materials. We are
