The West Africa Ebola virus epidemic now appears to be coming to an end. In the proposed model, we simulate changes in population behavior that help to explain the observed transmission dynamics. We introduce an EVD transmission model accompanied by

The goal of DTRA's Biosurveillance Ecosystem (BSVE) program is to significantly reduce the time required to identify threats to human health, whether of malicious or natural origin, and respond appropriately. Draper Laboratory is leading a team to de

Electrochemical reduction of dioxygen in aqueous media can proceed to water, hydrogen peroxide, or a mixture of the two. The production of hydrogen peroxide, classically established with the rotated ring-disk electrode, can also be quantitatively ass

Gold clusters stabilized by chemisorbed monolayers of octane-, dodecaneor hexadecanethiolate have been investigated in solution and in the solid phase. These materials can be pumped free of solvent to form a dark brown solid that can be re-dissolved

A new application of interdigitated array (IDA) electrodes is described for diffusion measurements of electrochemical probes dissolved in thin, lyotropic liquid crystalline films. The liquid crystal is a solution of 32% (w/w) lithium 4-trans-n-pentyl

Anisotropic diffusion of electroactive probes incorporated into monodomain lamellar phases of 50 wt % cesium pentadecafluorooctanoate (CsPDFO)/D[sub 2]O has been detected using cyclic voltammetry. The diffusional anisotropy ratios, D[sub [perpendicul

The ability to monitor and detect chemical warfare agents and their degradation compounds continues to be of utmost importance. Remote on-site field analysis of these compounds is also extremely important as it relates to treaty verification for the
