Colloidal synthesis of metal oxide nanocrystals and thin films Fredrik Söderlind
... In this thesis, nanocrystals and thin films of magnetic and ferroelectric metal oxides, e.g. RE2O3 (RE = Y, Gd, Dy), GdFeO3, Gd3Fe5O12, Na0.5K0.5NbO3, have been prepared by colloidal and sol-gel methods. The sizes of the nanocrystals were in the range 3-15 nm and different carboxylic acids, e.g. ole ...

... So, the flux through the Gaussian surface is: Φ=EA+0+0+0+0-EA=0, The total flux is zero even though the flux through sides 1 and 6 is non-zero. According to Gauss’ Law there is zero charge enclosed in the box. This should make sense since if we had enclosed a positive charge in the box we would have ...
