Razvoj nove EDXRF metode za određivanje sadržaja olovo(II) oksida

2012
U radu je primijenjena EDXRF tehnika (energijsko disperzna fluorescencija rendgenskih zraka) te je razvijena metoda za određivanje koncentracije olovo (II) oksida u realnim uzorcima. Pripremljene su standardne otopine olovnih iona, koncentracija 1, 10, 20, 30, 40, 50, 60, 70, 80, 90 i 100 ppm i dobiven je baždarni pravac za olovo (II) oksid.

Ab-initio výpočty elektronických a strukturních vlastností olovo-zirkonátu-titanátu (PZT)

Tato práce je zaměřena na výpočty difuzních bariér kyslíkových vakancí v olovo-zirkonátu-titanátu a jeho komponent pomocí teorie funkcionálu hustoty. Zjistili jsme, že velikost bariér je různá v olovo titanátu a olovo zirkonátu, což je způsobené rozdílnou lokalizací elektronů pocházejících ze vzniku kyslíkových vakancí.
