Autor: Patrícia M. Dias, Lilian Kinouti, Vera R. L. Constantino, Ana M. D. C. Ferreira, Marcos B. Gonçalves, Rafael R. do Nascimento, Helena M. Petrilli, Marília Caldas, Regina C. G. Frem
Publikováno v: Química Nova, Vol 33, Iss 10, Pp 2135-2142 (2010)
Herein, the immobilization of some Schiff base-copper(II) complexes in smectite clays is described as a strategy for the heterogenization of homogeneous catalysts. The obtained materials were characterized by spectroscopic techniques, mostly UV/Vis,

Hyperfine coupling effects induced by out-of-plane magnetic field throughout the two-electron spin blockade regime in a vertical quantum dot molecule
Autor: C. Payette, D. G. Austing, G. Yu, J. A. Gupta, Marília Caldas, Nelson Studart
With two weakly coupled vertical quantum dots we investigate how fine features in the tunneling current caused by electron‐spin nuclear‐spin coupling behave throughout the two‐electron spin blockade regime with an out‐of‐plane magnetic fiel

Inclusion of Phonon Dispersion and its Influence on Electrical Characteristic Degradation due to Heating Effects in Nanoscale FD-SOI Devices
Autor: Dragica Vasileska, Katerina Raleva, Stephen M. Goodnick, Marília Caldas, Nelson Studart
Publikováno v: AIP Conference Proceedings.
We address the most critical issue in nano‐devices: the degradation due to lattice heating. We consider different dispersions for the acoustic and optical phonon modes. We find that in small devices, due to the velocity overshoot effect lattice hea
