Effect of structural singularities on superwettability of SiO₂-based coatings
(Universidade Federal de São Carlos, 2019-11-07)
A detailed study on the correlation between structural singularities and wettability of neat and chemically modified coatings prepared from layer-by-layer (LbL) assembled silica nanoparticles (SiO₂) was performed. ...
Desenvolvimento de cerâmicas refratárias engenheiradas densas e porosas
(Universidade Federal de São Carlos, 2019-09-04)
High temperature processes are of great importance as they are widely applied in the manufacture of commodities, consumer goods and advanced materials. For these processes to be possible, the thermal environment in which ...
