Fig. 3 displays the XPS spectrum of the BST/Si-NPA film sample annealed at 700 °C for 1 h, where the detected elements on the surface of BST/Si-NPA film are Ba, Sr, Ti and O only, suggesting that the film is probably composed of barium strontium titanate. The absence of Si in the components of the BST/Si-NPA film indicates that the …

Ultrathin films of barium oxide were grown on Ag(001) and Ag(111) using the evaporation of Ba metal in an O 2 atmosphere by molecular beam epitaxy. Ultraviolet photoemission spectroscopy reveals that films consisting of predominantly BaO or BaO 2 result in Ag(001) work function reductions of 1.74 eV and 0.64 eV, respectively. On the …

Fujimoto et al. noted that when they used low-concentration barium (60 w/v%), the recurrent bleeding rate during the 7 months post-treatment was high at 54.5% . Our present findings are comparable to those of the studies using a high concentration of barium, and our patients did not experience any complications. We therefore propose that a ...

Percent Concentration. One way to describe the concentration of a solution is by the percent of the solution that is composed of the solute. This percentage can be determined in one of three ways: (1) the mass of the solute divided by the mass of solution, (2) the volume of the solute divided by the volume of the solution, or (3) the …

Barium meal, e.g. E-Z HD 250% w/v. A high-density, low-viscosity barium is required for a double-contrast barium meal to give a good thin coating that is still sufficiently dense to give satisfactory opacification. E-Z HD fulfils these requirements. It also contains simethicone (an anti-ing and coating agent) and sorbitol (a coating agent).
