1. Estudo de tratamentos com lítio no combate da reação álcali-agregado / Study of lithium treatments in mitigating alkali-aggregate reaction
The alkali-aggregate reaction (AAR) is one of the deterioration processes of concrete that most affects the structures of hydroelectric plants, concrete dams and bridges. In recent years, the efficiency of lithium based compounds to mitigate RAA has been proven in both the prevention and repair of the affected structures. With regards to treatment, the main

2. Estudos voltamétricos e microgravimétricos da deposição em subtensão de cádmio e chumbo sobre filmes finos de selênio / Voltammetric and microgravimetric studies of underpotential deposition of cadmium and lead on selenium thin films
Cd and Pb underpotential deposition (UPD) on gold electrode and selenium thin film, from acid media, were studied using cyclic voltammetry (CV) and electrochemical quartz crystal microbalance (EQCM). Different form of deposition for cadmium and lead were observed on gold electrode and selenium thin film. The presence of one peak in the positive sweep with a

3. ReptaÃÃo de um fio em uma cavidade bidimensional
The term âreptationâ is associated with the type of movement executed for reptiles, specifically the serpents, being used to describe the object diffusion with the topology of the line. The reptation of a wire injected in a cavity is studied through measures of the average quadratic displacement
of a point of the wire, in function of the length h injec Publicado em: 2007
