Synthesis and graphitization of phenolic resins for carbon-containing refractory applications
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ciência e Engenharia de Materiais - PPGCEMCâmpus São Carlos, 2020-02-03)
Carbon-containing refractories’ (CCRs) present special chemical and thermomechanical properties, which depend on the presence of carbonaceous phase with a structure similar to those of graphite. However, phenolic resins ...

Simultaneous voltammetric detection of ascorbic acid, dopamine and uric acid using a pyrolytic graphite electrode modified into dopamine solution
(ELSEVIER SCIENCE BV, 2008)
Pyrolytic graphite electrodes (PGE) were modified into dopamine solutions using phosphate buffer solutions, pH 10 and 6.5, as supporting electrolyte. The modification process involved a previous anodization of the working ...
