Nanotubos de carbono interagindo com vitaminaS B3 e C: um estudo de primeiros princípios
(Universidade Federal de Santa Maria, 2008-03-18)
This work presents a theoretical study about the interaction between pristine or functionalized B3 and C vitamins with semiconducting carbon nanotubes (8,0) through first principles simulations. We evaluate the structural ...
Vidro de spin e antiferromagnetismo com interacão de pareamento BCS local
(Universidade Federal de Santa Maria, 2005-07-12)
In this work the competition among spin glass(SG), antiferromagnetism (AF) and BCS pairs formation (PAIR) in real space is investigated. The model consists of an Ising spin glass term and a local BCS term that favors double ...
Estudo de primeiros princípios da interacão de monóxido de carbono com nanotubos de carbono semicondutores
(Universidade Federal de Santa Maria, 2004-10-08)
In this work we study the interaction of carbon monoxide with semiconducting (8,0)carbon nanotube through a first principles theoretical approach. Using density functional theory based methods, we show that radial ...
