Phase Segregation on the Nanoscale in Na 2 C 60

Na2C60 is believed to be an electron-hole counterpart of the Mott-Jahn–Teller insulator A4C60 salts. We present a study of infrared, ESR, NMR spectroscopy, X-ray diffraction, chemical composition and neutron scattering on this compound. Our spectroscopic results at room temperature can be reconciled in a picture of segregated, separate regions of the size 3–10 nm. We observe a significant insul...

Phase Equilibria of the Ternary System Water + Phosphoric Acid + 1-Nonanol at Different Temperatures

The purpose of this reaserch is to measure the phase equilibrium data of the ternary system (water + phosphoric acid + 1-nonanol) at different temperatures. Experimental solubility curves and tie-line points for the system were obtained at T = 298.2, 308.2 and 318.2 K and ambient pressure. The binodal curve data were detected by the cloud point method. The mass fractions of each layer ...

Solubility of corundum in the system Al2O3–SiO2–H2O–NaCl at 800 °C and 10 kbar

The solubility of corundum was measured at 800 °C and 10 kbar in NaCl–H2O–SiO2 fluids over NaCl mole fractions (XNaCl) of 0 to 0.5 and SiO2 concentrations of zero to quartz or albite+melt saturation, depending on XNaCl. Experiments were performed in a piston-cylinder apparatus. Dissolved Al2O3 and SiO2 were determined by weight losses of corundum and quartz crystals, or by bulk compositions of ...
