Magnetismo de nanofios de cobalto e níquel fabricados por eletrodeposição em alumina anódica porosa
(Universidade Federal de São Carlos, 2015-03-04)
In this thesis were investigated the magnetic properties of magnetic nanowire arrays of Co and Ni electrodeposited in porous anodic alumina templates. The electrochemical method was employed in the manufacturing steps of ...
Processamento e propriedades do sistema ferroelétrico (Li,K,Na)(Nb,Ta)O3 dopado com CuO
(Universidade Federal de São Carlos, 2015-03-09)
The search for new lead-free piezoelectric materials has been a major goal of many scientists in recent years. The main cause is the replacement of widely used lead zirconate titanate (PZT) based ceramics due to the highly ...
Efeito da modulação da topologia do confinamento em sistemas quase zero-dimensionais induzida por campo elétrico
(Universidade Federal de São Carlos, 2015-04-01)
Quantum dots grown by epitaxial techniques for optical and transport studies are usually capped by a layer of the same material on which the QDs were grown. Recently, several studies have shown how the growth parameters ...
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. ...
