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 ...

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 ...

DoD is concerned about circadian rhythm misalignment in military personnel as it is known to affect judgment, psychomotor skills, and may lead to or be triggered by Post-Traumatic Stress Disorder (PTSD). Correction or maintenance of circadian phase in soldiers participating in military night operations or planning for trans-meridian flights is also of interest. In addition, many veterans who suffe ...

Improving vehicle fuel efficiency for the military can significantly reduce costs and reduce risk to solider safety. One way to improve vehicle efficiency for new and legacy vehicles is to reduce frictional loses in the drivetrain through use of lower viscosity lubricants. However, this comes with the risk of reducing durability of drivetrain components through increased wear, pitting and scuffing ...

Clinical monitoring of mental health status has not evolved much from the routine meeting between patient and clinician, which suffers from a lack of quantification, irregular and anecdotal reporting, and does not necessarily include input from family. This is unfortunate given current technology, in which people routinely volunteer to track their own health related behavior, such as exercise and ...

Novel photonic structures, such as periodic metal-dielectric photonic bandgap structures (MDPBG) have the potential to revolutionize the field of optical windows. The large mismatch in the permittivities of the metal and dielectric creates resonant tunneling, which allows for high transmission in regions where metals are typically opaque. This property makes MDPBGs very attractive for screening or ...

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

"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 ...

On-site activated decontaminants will revolutionize chemical and biological decon because the activated solution is produced on demand, without the limitations of traditional pre-made mixtures. TDAs system uses electrical activation to convert battery power into reactive chemicals that quickly destroy chemical and biological warfare agents. Prior to activation, the decontaminant mixture can be saf ...

Approximately 5-6% of military injuries involve some form of major peripheral nerve injury that has little chance of spontaneous healing. Currently these injuries lead to major impairment of voluntary muscle function in the limbs and extremities, making tasks of walking, reaching, grasping, etc. very difficult or impossible for many patients. Focusing therapeutic treatments to segmental nerve in ...
