Perchlorate is a widely used component of solid fuel, missile and rocket propellants, explosives, and pyrotechnics. It has been shown to reduce iodide uptake into the thyroid gland. The U.S. Environmental Protection Agency (EPA) has found perchlorate contamination in 18 states and believes contamination may exist in as many as 39 states. In early January 2005, the National Academy of Science ...

Lead in household paint and dust is a serious health hazard, as low-level lead exposure can result in a number of adverse health effects, especially in children. Onsite and real-time detection and quantification of lead in paint/dust are very important to homeowners and certified lead-based paint removal professionals. Toward this end, both field-portable equipment (such as X-ray fluorescenc ...

Ganuna (7)-ray lenses are an advanced technology currently under development at Argonne National Laboratory for arms control application. The purpose of this proposal is to address whether y-ray lens technology can enable an improved system for imaging radioactive isotopes in patients. In nuclear medicine, it is often desirable to generate a y-ray image that shows the exact areas where an emitting ...

As an alternative to holographic laser radar, AMPS will develop a 3-D imaging concept that collects far-field intensity speckle patterns. This kind of measurement greatly relaxes the tolerances on vibration and coherence length. However, phase retrieval will be required to retrieve a 3-D image. Phase retrieval algorithms typically utilize some type of prior knowledge about the object. In industria ...

Relational Geometric Synthese (RGS) is a new object-oriented paradigm for 3-D geometric design. In RGS-based design, many qualitative and quantitative relationships between geometric objects are captured in a way that permits automatic update, preserving these relationships, following changes in underlying objects. Other advantages include support of a wide variety of curve and surface types; avoi ...

Applied Thin Films, Inc. proposes to use and an innovative aluminum phosphate solution based coating material to act as a sacrificial barrier layer to protect zirconia thermal barrier coatings from molten CMAS ingress and attack. The proposed coating material, known as Cerablak™, will ideally prevent any decrease in zirconia TBC lifetime expectancy and insulation efficiency due to CMAS infiltra ...

Extending gun barrel life has been a long-standing goal for the US Air Force and other DoD agencies. Currently-used chrome plated barrels are susceptible to erosion and corrosion which affects the accuracy of fired bullets due to material loss along the inner surface. The primary cause of barrel degradation is the poor quality chrome coating and attack of steel inner surface by hot gases and comb ...
