Standards Development to Ensure Reliable Breath Analysis in the Field

Ongoing
Numerous volatile organic compounds (VOCs) have been identified in human breath. These compounds can be produced by the body or by organisms in the body (e.g., bacteria or viruses) and provide a non-invasive window into human health. Inexpensive point-of-care devices are being developed to diagnose

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

Ultrafast Spectroscopy to Advance Microelectronics

Ongoing
Continued advancement in microelectronics, including analog and digital electronics, power electronics, optics and photonics, and micromechanics for memory, processing, sensing, and communications as defined by the OSTP “National Strategy on Microelectronics Research,” requires knowledge of material

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
