Fernando Galembeck
Fernando Galembeck, Brazilian physical chemist (São Paulo 21 January 1943 – Discovered osmosedimentation effect (1977), centrifugal ultrafiltration, pressure-driven pervaporation (1990) and tangential electrophoretic depolarization Discovered that atmospheric water can acquire electric charges and transfer them to other solid and liquid materials, a phenomenon known as higroelectricity (2010) Described a capacitor that loads spontaneously when exposed to moist air Demonstrated that electrization in dielectric materials occurs faster when the atmosphere is moist Proposed that atmosphere is a charge reservoir for dielectric materials Demonstrated that the friction between dielectric materials poses fixed and stable patterns of electric charges with a non-uniform distribution in the two sides of material and in some cases the main component of friction is only triboelectrization Proposed a new model of electrization of dielectrics Demonstrated that water vapor adsorption on insulating material surfaces or isolated metal leads to accumulation of electric charges on them Suggested new types of tensioactive chemicals Proposed the development of new polymeric nanocomposites and microcomposites Discovered that latexes present complex electric nanostructures that permitted the ionic amelioration of polymers Demonstrated that one could create submicrometric structures in a silica surface deposited in silicon monocrystal Demonstrated the role of electrostatic adhesion in nanocomposites formation SOME CONTRIBUTIONS/BIBLIOGRAPHY With L.C.
