Estudo da alumina anódica porosa como sensor para diferentes gases
(Universidade Federal de São Carlos, 2013-04-18)
In this project we studied the porous anodic alumina as a possible application in gas sensors with high sensitivity. Initially we seek a configuration of anodic porous alumina (PA) and the type of gas or vapor in which ...
Efeitos de spin em diodos de tunelamento ressonante tipo-p
(Universidade Federal de São Carlos, 2012-03-27)
In this work, we have investigated the spin effects in p-i-p GaAs/AlAs resonant tunneling diodes under magnetic field parallel to the tunnel current. The spin-dependent tunneling of carriers was studied by analyzing the ...
Caracterização das propriedades ópticas e de spin de poços quânticos de InGaAsN/GaAs
(Universidade Federal de São Carlos, 2015-03-30)
In this work, it was investigated the optical and magneto-optical properties of In- GaAsN/GaAs and InGaAs/GaAs double quantum wells. It was performed a systematic experimental study of photoluminescence (PL) as a function ...
Propriedades espectroscópicas da ação antimicrobiana do peptídeo polycerradin
(Universidade Federal de São Carlos, 2015-02-03)
The spectroscopy is a technique based on light-matter interaction, which provides information about the composition and structure of molecules. For this reason, it is used in various fields of science, including the biology. ...
