The high-pressure synthesis of the rhombohedral LaCuO 3 was optimized in terms of the applied pressure and temperature, the synthesis time and the amount of the oxidizing agent. Essentially single-phase samples were obtained at 5 GPa and 1400掳C. Upon heating under ambient pressure the ...
La cuochina sopraffina 05/25/20 11:49 Finding an easy homemade pizza recipe can be overwhelming: if you search on Google, the amount of results you get is absolutely mad. The reason why so many pizza recipes exist is simple: everyone has its own pizza recipe and everyone thinks it’s...
Shock loading experiments up to 70 GPa have been carried out on single crystal specimens of LaCuO, LaNiO, LaSrCuOand LaSrNiO. An apparent lattice expansion after compression was observed in LaCuO. In contrast to this, no cell volume change was detected in LaNiOwhile the Sr-doped crystals sho...
