In this project, Arktonics proposes to develop monolithically integrated high-performance (Si)GeSn lasers by using the novel aspect ratio trapping (ART) growth technology. The proposed transformative laser architecture is expected to fundamentally address the long-standing challenges of the missing high-performance light emitter to complete the whole suite of Si-photonics to enable many new applic ...

As the single largest consumer of materials and energy use worldwide, the construction sector remains a prime target for materials reuse reform. (Krausmann et al., 2009; De Ia Rue du Can & Price, 2008). Construction and ongoing operation of the built environment extracts a significant amount of resources -- and on an ongoing basis. According to the U.S. Green Building Council (USGBC), buildings ac ...

Per- and polyfluoroalkyl substances (PFAS) have emerged as a pervasive and persistent threat to drinking water throughout the world. Called ‘forever chemicals” because their high stability leads PFAS to build up in the environment. PFAS accumulates in the blood from exposures and is associated with various cancers and other illnesses. There is an urgent need for a technology that can both remo ...

The EPA has established health advisory levels at 70 parts per trillion (ppt) for combined PFAS concentration. Water resources are susceptible to contamination by PFAS release from industry and landfill sites. Consequently, there is a need for on-site pretreatment technologies for PFASs in industrial wastewater. Electrochemical treatment has been shown to be effective for the mineralization of PFA ...

Aging infrastructure is a major challenge faced by the water utilities in the USA and across the globe, and with an overall rating of D by the ASCE, water distribution systems are no exception. Approximately 240,000 water main breaks occur in US systems every year with a cost of at least $3.6 billion. As such, innovative, economical, and sustainable solutions are needed in renewing the water trans ...

The capability to reliably and remotely detect and track tactical surface targets in a high-velocity projectile after launch is a critical need. The discrimination of man-made objects can be assisted by the detector technology, with options including two-color detectors and polarimetric filtering in the thermal infrared bands. The level of complexity in the focal plane array affects its survivabil ...

The integration of physical and cyber systems have dramatically increased the vulnerability and the attack surface of cyber physical systems. The most common architecture to achieve the monitoring and control of the critical infrastructures is the Supervisory Control and Data Acquisition (SCADA) systems. As SCADA systems become interconnected with Internet resources and services, they become easy ...

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 ...

Photovoltaics (solar cells) are an attractive technology to provide renewable energy sources for forward operating bases, man-portable power sources, and tactical applications. Solar arrays can provide base power greatly reducing the need for logistical fuels, continuous battery recharging for warfighters on the move, and integrated power sources for remote, autonomous systems, e.g. UAVs. To be ef ...

This Phase I SBIR OSD project proposes the development and testing of a porous metal anode-supported intermediate-temperature solid oxide fuel cell (PMS-IT-SOFC) that exhibits high electrochemical efficiency, high degree of fuel utilization (reformed JP-8, diesel, or dodecane), and low operating temperature characteristics intended for high efficiency, logistic-fueled propulsion and power systems ...
