On 11 March 2011, the day of the unforgettable disaster of the 9 magnitude Tohoku earthquake and quickly followed by the devastating Tsunami, a damageable amount of radionuclides had dispersed from the Fukushima Daiichi's damaged nuclear reactors. Decontamination of the dispersed radionuclides from seawater and soil, due to the huge amounts of coexisting ions with competitive functionalities, h...

The potent vasoconstrictor endothelin leads to smooth muscle cell depolarization and increases in intracellular Ca2+. Although effects of endothelin on calcium channels have been described, it also has been speculated that endothelim may activate additional ion channels. The purpose of the present study was to identify an alternative ion current that could play a role in depolarizing cells in r...

Abstract The Los Alamos Neutron Science Center (LANSCE) H - ion source has provided stable output for decades of LANL mission needs, but its maximum beam remained the same at ∼15 mA. A roadblock to improving been a lack thorough understanding internal mechanisms LANSCE source. Ion Source Laser Diagnostic Stand (HLDS) was recently built and commissioned explore these using laser absorption techn...

Natural soil Cs concentration is low and non-toxic to plants. The stable isotope Cs is present at concentrations close to 25 μg per g of dry soil [23] and only specially Cs-rich pollucite might cause environmental toxicity of Cs, as in areas of Manitoba [20]. Additionally, two radioisotopes of Cs, Cs and Cs, originating from industry, testing of thermonuclear weapons and from radiation accident...

Chemical and thermal performance of crystalline silicotitanate (CST) and resorcinolformaldehyde (RF) ion exchange media were predicted for column configurations designed for installation in high level waste tanks and intended for cesium removal from radioactive waste supernates. Modeling predictions for the processing of a known Savannah River Site tank waste composition were generated. In a tw...
