Geopolymer cements (GPs) possess the ability to quickly form high-strength, thermally-stable, and near-net shape structures at room temperature. Their chemical nature enables them to bond strongly to both metal and ceramic parts acting as refractory glue. Through our work in the Phase I STTR, a detailed understanding of the basic chemistry, structure, processing conditions, thermal behavior, and c ...

Many Unites States Army, and other Department of Defense (DoD) sites, are contaminated with a variety of contaminants including highly energetic compounds, such as 2,4,6-trinitrotoluene (TNT), hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX), chlorinated aliphatics (such as trichloroethylene,TCE) and chlorinated aromatics. These compounds often persist in soil or groundwater for extended periods of t ...

An assessment will be made of two quench-protection strategies for HTS conductors, one based on dielectric insulations with enhanced thermal properties and the other on a cryovaristor technology. Three insulations are considered: ceramic powders in Formvar, sputtered ceramics, and diamond films. Both strategies make use of established databases at CeramPhysics (except for diamond films). Additi ...

Cornerstone Research Group, Inc. (CRG), and partner University of Dayton Research Institute (UDRI) will develop a suite of materials and processes as enabling technology for achieving the radical production time and cost reductions envisioned by the replication approach to producing composite mirrors for aerospace optics. CRG will formulate and demonstrate a high-performance polymer resin cured a ...

Superconducting 3-30 MVA transformers for the Navy will have reduced size and weight, lower AC losses, and be liquid cryogen free. The smaller size and lower weight will have benefits in increasing capacity in limited ship spaces or reducing the area requirements for existing capacities. In addition to these more conventional attributes, the superconducting transformer has the potential of havin ...

The Air Force is currently pursuing the development of high temperature superconducting airborne generators, and air core transformers. Coated YBCO superconductors can enable these applications. More needs to be known about the stability of these YBCO coated superconductors when wound into coils, so that the best approaches for quench protection can be determined. Our STTR Phase I will investi ...

Presently available atmospheric pressure plasma sources of reactive radicals, ions or intense VUV/UV radiation for materials processing, treatment of toxic waste and removal of surface contamination use arc discharges (DC or low frequency), corona or rf discharges, have too small a volume or their volumetric efficiency is too low, and operate at too high a neutral gas temperatures for many sensiti ...

The phase I technical objectives are to use existing lifetime based PSP technology and identify a combination of existing probes and a binder that will provide a temperature-insensitive PSP measurement. These will be accomplished by extending the current lifetime-based systems that employ two-gate detection and by adding a second probe and a third or fourth gate. The proposed system will be cons ...
