Insights on the dissolution of water in an albite melt at high pressures and temperatures from a direct structural analysis.

The water dissolution mechanism in silicate melts under high pressures is not well understood. Here we present the first direct structure investigation of a water-saturated albite melt to monitor the interactions between water and the network structure of silicate melt at the molecular level. In situ high-energy X-ray diffraction was carried out on the NaAlSiO-HO system at 800 °C and 300 MPa, at the Advanced Photon Source synchrotron facility.

Effect of AlO Seed-Layer on the Dielectric and Electrical Properties of Ultrathin MgO Films Fabricated Using Atomic Layer Deposition.

Metal/insulator/metal (M/I/M) trilayers of Al/MgO/Al with ultrathin MgO in the thickness range of 2.20-4.40 nm were fabricated using sputtering and atomic layer deposition (ALD).
