Individual 1-3 mm biotite and muscovite clasts from Hanford sediment were contacted with 0.08 M CsNO3. They were examined using electron or X-ray microprobe methods, as intact specimens or sectioned perpendicular to their basal planes. Cs+ was observed to preferentially sorb to mica edges, steps on mica surfaces, or fractured regions. The localization of Cs conformed to hypothesized strong bind...

Creating next-generation pyrotechnic emitters capable of dynamically controllable light output requires a paradigm shift away from emission control via formulation. This work demonstrates the ability to modulate intensity flame with 2.46 GHz microwave energy within multimodal cavity. Stoichiometric mixtures three systems are investigated: magnesium fuel oxidizers NaNO3, KNO3, or CsNO3. Using ti...

The adsorption of pyrazolone(HPMSP), Calix[4]-arene,Cu and Cs, on carbon nanotube(CNT) atroom temperature has been investigated using spectroscopy.Uv spectroscopy indicated that pyrazolone molecules adsorbed on carbon nanotube at roomtemperature in compared calix[4]- arene molecules adsorbed approximately same.The amount ofpyrazolone(HPMSP) adsorb 3.8. le mol/g and amount calix[4]-arene adsorbe...

Sodium bearing waste (SBW) having a high loading of sodium salts (typical of the SBW stored at Hanford) must be pretreated before it can be incorporated in a hydroceramic waste form. One such method, using thermal decomposition of the nitrate/nitrite ions in the SBW is described. Calcination of the SBW with sucrose and various aluminosilicate sources produced a granular solid that was solidifie...

Cs ion exchange in RbTiOPO4 and (Yb,Nb):RTP/RTP(001) has been used to locally increase the refractive indices for waveguide circuit fabrication. Ti masks were fabricated on RTP samples by conventional photolithography. Cs exchange was done using a CsNO3 melt at 698 K during 2 h. Elemental analysis confirms an Cs profile with a variable depth. Apparently the Cs exchange is disfavored in the dope...
