Complex wounds including traumatic, chemical, chronic or surgical wounds present a significant challenge to care givers. Wound healing, being a complex and multifaceted process, differs significantly based on the type of wound and the underlining health of the patient. It is well established that factors like impaired perfusion, infection, existence of metabolic disorders such as diabetes, bad nut ...

This proposal will investigate body armor systems to the effects of burst fire. In Phase I, the team of researchers will investigate the spatial distribution of impacts of common burst fire capable rifles, demonstrate a statistical analysis technique, and demonstrate a ballistic model approach while applying this research to a surrogate body armor solution. The program will begin with an analysi ...

SI2 Technologies, Inc. (SI2) and Drexel University propose to develop printed, flexible, high-performance ultracapacitors to meet the Armys need for lightweight energy storage. SI2 will leverage its demonstrated expertise in ink jet printing and Drexels expertise with carbon nanoparticle synthesis. SI2 has considerable experience in the roll-to-roll deposition of conductive ink patterns. These ...

"HgCdTe is the material of choice for high performance infrared red focal plane arrays (IRFPA) used in militarys night vision systems. One of the major problems IRFPA manufacturers face is the ineffective passivation of the highly reticulated HgCdTe detector surfaces, which results in poor performance. Furthermore, newly evolved FPA technology requires the creation of much challenging high-aspect ...

In Phase II we propose to optimize wafer scale MoS2 deposition process to fabricate uniform large area monolayer and multi-layer MoS2 films and analyze the defects on these films. Monolayer regions that can result in device periphery larger than 50m will be targeted. Further, the charge transfer doping process using TiOx will be optimized for MoS2 multi-layer and RF transistors will be fabrication ...

Antimicrobial treatment of military textile systems is intended to provide enhanced protection to the Warfighter in the field by preventing colonization of harmful bacteria that cause problems such as odor, dermatitis, impetigo, cellulitis, and other skin irritations. Current treatments can impart antimicrobial functionality to textiles; however, they all possess broad-spectrum antimicrobial activ ...

Spontaneous emission is a quantum mechanical process that represents the main source of phase noise in state-of-the-art semiconductor lasers, limiting their coherence, and their suitability for high-speed communication and sensing applications. This proposal aims to develop ultra-high coherence semiconductor lasers on the Silicon/III-V platform with a quantum linewidth of

A critical step in the extraction of elements from ore, especially rare earth elements that are found in complex minerals, is separation. Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry. The particles with attached air bubbles are then ca ...

Empirical-based mathematical framework and computer algorithms, for representing human perception and cognition processes and limitations, which influence the recognition of salient information about rapidly changing events.

Due to the limited amount of rhenium present in the earths crust (approximately 1-2 part per billion) there is a significant benefit to be realized in recovering for reuse the rhenium from scrap material, spent catalysts, or end-of-life superalloys. Rhenium is found in molybdenum-copper porphyry deposits. If rhenium is present in ore that is processed, it will show up in the resulting molybdenum ...
