  • Publication number: 20130134098
    Abstract: Methods for treating water to remove radium include contacting the water with a magnetic adsorbent comprising manganese oxide(s), and applying a magnetic field to separate the magnetic adsorbent from the water, whereby radium is removed from the water. The methods may additionally include regenerating the magnetic adsorbent, and contacting the water with regenerated magnetic adsorbent. Alternately, calcium and/or strontium may be precipitated as carbonate salts from lime-treated water containing radium and barium without precipitating a significant fraction of the barium or radium; and removing radium from calcium- and strontium-free water by precipitating the barium and radium as carbonate salts. The barium- and radium carbonate precipitate may be redissolved in hydrochloric acid and disposed of by deep-well injection.

  • Publication number: 20130109147
    Abstract: Some embodiments include methods of forming memory cells. Metal oxide may be deposited over a first electrode, with the deposited metal oxide having a relatively low degree of crystallinity. The degree of crystallinity within the metal oxide may be increased after the deposition of the metal oxide. A dielectric material may be formed over the metal oxide, and a second electrode may be formed over the dielectric material. The degree of crystallinity may be increased with a thermal treatment. The thermal treatment may be conducted before, during, and/or after formation of the dielectric material.

  • Publication number: 20130028983
    Abstract: There is provided on-demand, oxygen generating topical compositions having a built-in indicator specifically to indicate a color change upon the complete mixing of the oxygen precursor and catalyst. The first part of the composition contains a carrier and manganese dioxide (MnO2) nanoparticles. The second part of the composition comprises the oxygen precursor; hydrogen peroxide. When the two parts, one with manganese dioxide nanoparticles and exhibiting a characteristic color, (e.g. yellow brown) and the second part with hydrogen peroxide are mixed together, the color imparted by the manganese dioxide nanoparticles essentially disappears and the final composition (enriched with oxygen) either appears colorless or takes on the original color of the catalyst. Thus, the manganese dioxide catalyst nanoparticles themselves serve as the colorimetric indicator of peroxide decomposition to oxygen, precluding the need for an external colorant.
