Effects of dependence between solid solution and surface excess in nanoparticles
(2010)
In this work, samples of 10 mol% Mg-doped SnO2 were synthesized by Pechini's method and calcined at 500°C. Previous analysis suggests that the additive is preferentially located on the surface of nanoparticles as a surface ...
Spin-wave fluctuations in ferrimagnetic Mgx Fe3-x O4 nanoparticles
(2010)
We have performed a systematic study of the magnetic properties of a series of ferrimagnetic nanoparticles of Mgx Fe3-x O4 (0.8times;1.5) prepared by the combustion reaction method. The magnetization data can be well fitted ...
Graftização de anidrido maleico em polipropileno, por processamento reativo, na presença de nanopartículas
(Centro Universitário da FEI, São Bernardo do Campo, 2010)
Neste trabalho explorou-se a viabilidade de nanorreatores de montmorilonita e peróxido, para aumentar a seletividade das reações de graftização com relação às reações de quebra de cadeia, durante o processo de graftização ...
