    摘要： A forensic marker is disclosed including a marker that is added to the host material and is detectable for at least the expected life of the host material. The marker is inert with respect to the host material in that it does not significantly affect the desired qualities of the host material (e.g. weight, adhesive properties, structural integrity, etc). The marker is detectable, for example, by instruments, during the life of the host material.

    摘要： Materials and methods of making low-sintering-temperature glass waste forms that sequester radioactive iodine in a strong and durable structure. First, the iodine is captured by an adsorbant, which forms an iodine-loaded material, e.g., AgI, AgI-zeolite, AgI-mordenite, Ag-silica aerogel, ZnI2, CuI, or Bi5O7I. Next, particles of the iodine-loaded material are mixed with powdered frits of low-sintering-temperature glasses (comprising various oxides of Si, B, Bi, Pb, and Zn), and then sintered at a relatively low temperature, ranging from 425° C. to 550° C. The sintering converts the mixed powders into a solid block of a glassy waste form, having low iodine leaching rates. The vitrified glassy waste form can contain as much as 60 wt % AgI. A preferred glass, having a sintering temperature of 500° C. (below the silver iodide sublimation temperature of 500° C.) was identified that contains oxides of boron, bismuth, and zinc, while containing essentially no lead or silicon.

    摘要： Special high performance wavelength shifting compositions has been discovered and devised. Further, these compositions when properly distributed in a bulk medium having cooperative properties forms new media having totally unique and useful characteristics. In particular, a special phosphor is devised having a dual peak spectral output when stimulated with high energy photonic input. A dual activator formula is created such that simple manipulation of specified ratios permits flexibility in tuning of color temperature output of the phosphor emitter combination. When prepared with preferred particle sizes and densities, performance improvements are observed. Finally, these phosphors are combined with other special binder materials to form colloid media with well designed optical interaction cross section whereby light emitted from a high intensity blue diode semiconductor will experience just enough wavelength shift in precisely the desired portions of the spectrum, with high efficiency, to form a white LED not found in other systems.

    摘要： A process for treating alkaline wastes for vitrification. The process involves acidifying the wastes with an oxidizing agent such as nitric acid, then adding formic acid as a reducing agent, and then mixing with glass formers to produce a melter feed. The nitric acid contributes nitrates that act as an oxidant to balance the redox of the melter feed, prevent reduction of certain species to produce conducting metals, and lower the pH of the wastes to a suitable level for melter operation. The formic acid reduces mercury compounds to elemental mercury for removal by steam stripping, and MnO.sub.2 to the Mn(II) ion to prevent foaming of the glass melt. The optimum amounts of nitric acid and formic acid are determined in relation to the composition of the wastes, including the concentrations of mercury (II) and MnO.sub.2, noble metal compounds, nitrates, formates and so forth. The process minimizes the amount of hydrogen generated during treatment, while producing a redox-balanced feed for effective melter operation and a quality glass product.
