Abstract The different magnetic behaviors of LaCoO $$_3$$ 3 films grown on LaAlO and SrTiO substrates are related to the Co–O–Co bond angles constraints imposed Co–O lengths by substrate geometries. observed behavior is not consistent with ferromagnetism. Rather, long-range...

kinetic monte carlo simulation was applied to investigation of kinetics and mechanism of oxalic acid degradation by direct and heterogeneous catalytic ozonation. la-containing perovskites including lafeo3, lanio3, lacoo3 and lamno3 was studied as catalyst for oxalic acid ozonation. the reaction kinetic mechanisms of each abovementioned catalytic systems has been achieved. the rate constants val...
