Pulsed voltammetry is a characterization tool for electrochemical systems that has been around for many decades. Unlike the more commonly used cyclic voltammetry techniques, the additional degrees of freedom intrinsic to pulsed voltammetry techniques permit the decoupling of reaction kinetics from diffusion, and allow for the precise measurement of a range of reaction parameters, including the hal ...

We present a concept for improving standoff ground penetrating radar capabilities for detecting buried explosive hazards (BEH). Currently, standoff detection capabilities are limited to forward looking systems, which provide limited penetration of the ground surface due to the low grazing angle required for forward looking standoff detection. Additionally, forward looking arrays are somewhat limit ...

Real-time monitoring of wastewater quality remains an unsolved challenge in the treatment industry. The standard method of biological oxygen demand (BOD) yields slow results (five days); another standard method, chemical oxygen demand (COD), uses hazardous chemicals and does not provide direct information on potential for ecological pollution. The treatment industry has expressed need for the deve ...

In this Phase II project, Akita Innovations will improve the performance of our polymeric antifog coating with respect to antifog performance, abrasion resistance, and manufacturability. We will demonstrate a manufacturable material and process that meets all Army MIL-PRF-32432 requirements for protective eyewear, with superior antifog performance compared to existing products, and supply the Army ...

Conductive films that maintain transparency are a key element in many current products and industries, including electronic devices for touch screens and automobiles to defrost windows. Such films are also useful in military applications. By introducing a resistive taper in conductive films or antennas, overall performance can be improved by reducing backscattering and increasing sensitivity in an ...

LumArray proposes in Phase I to demonstrate that its direct-write maskless-photolithography system, the ZP-150, is capable of performing aligned cuts in 1D-grids suitable for the 45 nm node, in addition to writing patterns of arbitrary geometry as required in custom ASICs and a wide range of other DoD and Aerospace applications. In Phase II LumArray will propose to make upgrades to its ZP-150 syst ...

The NNSA-sponsored development of the Dynamic Compression Sector (DCS), at the Advanced Photon Source at Argonne National Laboratory, will permit real-time X-ray measurements (diffraction, imaging, scattering) in dynamically compressed materials, and enable understanding of the dynamics of materials response to intense shock waves, which heretofore has not been possible. Such studies are critical ...

STR proposes to build Categories via Context-Driven Dimensionality Reduction (C2D2R), a novel, highly efficient, and scalable information processing pipeline for joint learning of categories of entities and relations, and document topics.C2D2R operates in three stages: shallow pre-processing of text inputs, context-driven dimensionality reduction, and joint category inference and labeling. Our sys ...

An electromagnetic pulse (EMP) attack could cause widespread outage of the commercial electric power system that could last for weeks to months. Microgrids for defense critical infrastructure (DCI) should thus be equipped to operate in islanded mode for extended periods of time using only local fuel storage and renewable energy sources. The primary difference between operating a microgrid in islan ...

The project will develop a handheld instrument that detects, identifies, and categorizes radioactive sources based on gamma, thermal-, and fast-neutron signatures. Existing radioisotope identification devices (RIIDs) are typically biased toward gamma spectroscopy, and often use a simple, inefficient neutron counter. The recent development of Cs2LiYCl6:Ce (CLYC) has enabled neutron and gamma spectr ...
