The effect of MgO on structure and dielectric properties of aluminoborosilicate glasses was investigated. FTIR data indicated that glass network was mainly built by tetrahedral [SiO4], [BO4], [AlO4] and trigonal [BO3]. A small amount of AlO5 or AlO6 units also existed. The glass system was...

RO-Al2O3-B2O3-SiO2 (R = Ca, Mg) glasses containing different concentrations of TiO2 (ranging from 0 to 9 mol.%) were prepared by conventional melting method. When TiO2 was present in lower concentrations (≤ 6 mol.%), Fourier-transform infrared spectroscopy (FTIR) indicated that titanium ions...

LaNiO3(LNO) thin films were prepared on Si(100) substrates by a chemical solution deposition method. The orientation of LNO films was controlled by changing the acetic acid amount, concentration of the precursor solutions and pre-annealing time. The highly (100)- and (110)-oriented LNO films...
