Using Nanoparticle Scaffolds to Probe and Enhance the Catalytic Activity of Single and Coupled Enzyme Systems

Hastman D., Chiriboga M., Medintz I., U.S. Naval Research Laboratory, US

The use of nanoparticle (NP) scaffolds for enzymatic systems has proven to be a useful tool for sensing specific enzyme activity as well as enhancing the catalytic rates of these systems. Although, NP-induced enhancement has [...]

Silicon Nanowire Vertical Arrays with Porous Top Electrodes for Trace Vapor Preconcentration and Partial Separation

Giordano B., Pehrsson P., Johnson K., U.S. Naval Research Laboratory, US

Commercial Off the Self (COTS) technologies for chemical vapor detection of trace analytes in complex, unknown background environments, often underperform with respect to sensitivity and selectivity. We have developed a chemical preconcentrator based on a [...]

Novel Structure, Properties, and Synthesis of Refractory Carbides

Dyatkin B., Laskoski M., Rock B.Y., Qadri S., Kolel-Veetil M., Keller T.M., Gamache R.M., U.S. Naval Research Laboratory, US

Ultra-high temperature ceramics (UHTCs) and refractory carbides with high hardness and oxidation resistance demonstrate significant promise in armor and hypersonic engine applications. However, to date, they have been too brittle and expensive to widely implement [...]
