Nanoparticles represent an attractive alternative in coating processes due to their functional versatility, including surface, optical, conductive and catalytic properties. However, current processes of coating textile products with nanoparticles results in rapid loss of the nanoparticles during laundering or use, leading to a significant decrease in product durability and functionality and increa ...

Local water production for troops using standard membrane filtration processes presents a significant logistics burden because of high energy consumption for removing particles based on size-exclusion methods and the constant need to replace fouled membranes. A membraneless filtration method using dissolved CO2 has been demonstrated to separate charged particles through the mechanism of diffusioph ...

SIFT, JHU medicine and University of Central Florida are proposing to develop VANESSA (Virtual Analysis Networks and Explanations for Social Sensing Analysis) - a social sensing platform providing team diagnostics of interacting teams and recommendations for enhanced team functioning of human and human-cyber teams. The overall goal of VANESSA is to develop an adaptive technology platform with a fo ...

We propose an innovative mathematical approach to the analysis and design of multi-function adaptive antenna systems. It uses the idea of signal fragmentation that has passed significant prior testing and employs the methods and results from sampling theory, approximation theory, and numerical optimization. The fragmentation of a signal into a combination of short elementary pulses (wavelets) allo ...

Explosive & chem-bio sensors are necessary to provide situational awareness and early warning against threat events from homemade explosives and weapons of mass destruction (WMD), to protect personnel and assets in missions ranging from integrated-base defense to forward operating bases and reconnaissance. The Department of Defense is interested in reducing costs, labor, and footprint while enhanc ...

This STTR Phase I project aims at developing a lab-on-chip optical absorption spectrometer spanning 3-15 micron molecular fingerprint region, with monolithic integration of quantum cascade laser (QCL), quantum cascade detector (QCD) and slotted photonic crystal waveguides (PCWs) in a mid-infrared photonic waveguiding platform. Monolithic integration is achieved with a single epitaxially grown hete ...

TransWave Photonics, LLC in collaboration with Prof. Mikhail Belkin group at the University of Texas at Austin proposes to develop mid-wave infrared photonic integrated circuits based on monolithic integration of passive low-loss waveguides, thermo-optically tunable photonic elements, and quantum cascade laser gain sections within the same InGaAs/AlInAs/InP platform grown by metal-organic vapor ph ...

BakerRisk proposes to use their extensive experience with shock testing, pressure transducers, and accelerometers, along with expertise in animal testing and the study of traumatic brain injury provided by their collaborator, Dr. David Cook, to produce a biomechanical surrogate of a rat. This device will stand in for the animal specimen in a variety of laboratory and in the field tests, recording ...

Obscurant materials are used by the Army to protect both the soldier as well as military physical assets. Several obscuration systems have been developed over the years to defeat threats in all areas of the electromagnetic spectrum. Current obscurant materials typically consist of off-the-shelf or processed metal particles or flakes in which key properties such as particle size and aspect ratio ...

This Phase I program is focused on enhancement of the performance of MgZnO based solar blind detectors. MgZnO alloys have superior optoelectronic properties with bandgaps suitable for solar blind detection. Issues related to doping and miscibility will be addressed. This will involve the use of advanced MOCVD and MBE growth techniques and consideration of both Schottky and p-n junction devices. No ...
