Análise do comportamento de membranas cerâmicas de α-alumina/Pd para separação de gases a temperatura ambiente e baixas pressões
Bertotto, Raphael; Duarte, Jocelei; Santos, Venina dos; Andrade, Mára Zeni; Bergmann, Carlos Perez (2018) [Artigo de periódico]Membranas de compósitos Pd/α-Al2O3 com uma e duas camadas de Pd foram preparadas pelo processo electroless plating sobre tubos cerâmicos porosos. A análise de espectroscopia por dispersão de energia confirmou a composição ... -
Analysis of composite membranes in the separation of emulsions sunflower oil/water
Biron, Dionisio da Silva; Andrade, Mára Zeni; Bergmann, Carlos Perez; Santos, Venina dos (2017) [Artigo de periódico]Oil is a major pollutant of water resources, affects aquatic life, causing environmental degradation. Currently there is an increase in studies of membrane applied to separation of oil-water. Among these membranes, there ... -
Assessment of a system for the prediction of water permeability coefficient in pervious concretes
Ribeiro, Aline (UCS); Santos, Venina dos; Pagnussat, Daniel Tregnago; Brandalise, Rosmary Nichele (2018) [Artigo de periódico]Proposing a system which makes it possible to determine the water permeability coefficient in pervious concretes in a practical way, without the need of devices which require complex instrumentation, is one of the aims of ... -
