Estudo da ruptura dielétrica durante a anodização de zircônio e o seu efeito sobre o processo de dopagem anódica de ZrO2
(Universidade Federal de São Carlos, 2012-05-09)
In this work the fundamental aspects of electrolytic breakdown in ZrO2 films were investigated. The electrolytic breakdown is a type of dielectric breakdown that occurs during galvanostatic growth of anodic oxides. To ...
Hidrogéis Nanocompósitos Termossensíveis aplicados no crescimento de Células–tronco Mesenquimais e Condrócitos para a engenharia tecidual
(Universidade Federal de São Carlos, 2018-09-27)
Injectable biomaterials have gained prominence in tissue engineering since they present a minimal invasive option for therapeutic delivery. However, longer gelation time, instability of physicochemical properties, cytotoxicity ...
Síntese e estudo das propriedades fotoluminescentes e fotocatalíticas dos cristais de Ag2-2xMxWO4, (M = Mg e Zn)
(Universidade Federal de São Carlos, 2014-06-03)
This study aimed to investigate the photoluminescence and photocatalytic properties of the alpha phase of silver tungstate ( α-Ag2WO4 ) doped with Mg and Zn (where M = Mg or Zn and x = 0; 0,01; 0,02; 0,04 ou 0,08). The ...
Hidrogéis magneto-reponsivos para liberação estimulada de fármacos
(Universidade Federal de São Carlos, 2018-05-08)
Nanocomposite hydrogels modified with polysaccharides, minerals clay and magnetic nanoparticles of iron oxide functionalized with polymeric material were developed, allowing higher interaction between the nanoparticles and ...
Ternary nanocomposites based on cellulose nanocrystals, conductive materials and electrospun fibers applied in sensors for detection of heavy metals in water
(Universidade Federal de São Carlos, 2019-03-28)
The monitoring of water resources destined for consumption is a subject of outmost importance for population and ecosystems life quality maintenance. The degradation of these resources with heavy metals, usually associated ...

(Universidade Federal de São Carlos, 2017-10-27)
Brazilian researchers have performed out several works and developed several products from nanostructured materials, which has resulted in an expansion in its research. One of these research fields is focused on minimizing ...
Investigação da corrosão do aço carbono AISI 1020 em soluções de NaCl utilizando microscopia óptica in situ
(Universidade Federal de São Carlos, 2016-09-23)
According to recent information from the World Corrosion Organization, annually, approximately 2.2 trillion of global GDP is spent on corrosion-related damage. These expenses are almost the GDP of the seventh world economy ...
Estudo microestrutural dos contornos de grão em estágio inicial de formação no sistema cerâmico ZnO-Bi2O3
(Universidade Federal de São Carlos, 2019-08-28)
Polycrystalline materials have solid-solid interfaces known as grain boundary. These interfaces have long been treated as just a region of defects between the crystals (grains), but recent studies have shown that such ...
