Superconductivity has been realized in films of La$_{1-x}$Sr$_x$NiO$_2$. Here we report synthesis and characterization polycrystalline samples La$_{1-x}$Sr$_x$NiO$_3$ La$_{1-x}$Sr$_x$NiO$_2$ ($0\le x\le 0.2$). Magnetization resistivity measurements reveal that are paramagnetic metals exhibit insulating behavior. is not detected bulk The absence superconductivity may be due to the generation hyd...

In this work, bulk Czochralski-grown single crystals of 10 mol. % Al2O3 alloyed B-Ga2O3 - monoclinic 10% AGO or B-(Al0.1Ga0.9)2O3 are obtained, which show +0.20 eV increase in the bandgap compared with unintentionally doped B-Ga2O3. Further, growths 33% B-(Al0.33Ga0.67)2O3 and 50% B-(Al0.5Ga0.5)2O3 B-AlGaO3 produce polycrystalline single-phase material (B-AGO). All three compositions investigat...

Crystal growth from anhydrous hydrogen fluoride solutions of M2+ (M=Cu, Ag) and [AuF6]− gave M(AuF6)2 salts Ag). Similar attempts to prepare single crystals the corresponding nickel, zinc magnesium failed. The crystal structure Cu(AuF6)2 consists layers Cu2+ cations connected by anions, thus forming slabs. Only van der Waals interactions exist between adjacent Ag(AuF6)2 a three-dimensional fram...
