Comprehensive spectroscopic study of nitrogenated carbon nanotubes
(American Physical SocCollege PkEUA, 2004)
CARBONATAÇÃO ACELERADA EM CONCRETOS COMPOSTOS COM CINZA DE CASCA DE ARROZ DE DIFERENTES TEORES DE CARBONO GRAFÍTICO
(Universidade Federal de Santa MariaBREngenharia CivilUFSMPrograma de Pós-Graduação em Engenharia Civil, 2014-02-28)
Carbonation is a natural phenomenon observed in carbon structures, and it is a result of the combined presence of CO2 in the environment and moisture. Carbonation may lower the pH of the concrete to such an extent that the ...
Voltammetry of mercury (II) based on an organo-clay modified graphite electrode
Organo-clay complex of ligand-hexadecyltrimethylammonium with montmorillonite was made for the purpose of application as a preconcentration agent in a chemically modified carbon paste electrode for determination of mercury ...

Nitrogen substitution of carbon in graphite: Structure evolution toward molecular forms
(American Physical SocCollege PkEUA, 1998)
Use of porous graphitic carbon column for the separation of natural isomeric tropane alkaloids by capillary LC and mass spectrometry
(PERGAMON-ELSEVIER SCIENCE LTD, 2006-02-24)
This study presents the outstanding chromatographic selectivity of a porous graphitic carbon support for the separation of four isomeric tropane alkaloids from the stem-bark of Schizanthus grahamii (Solanaceae). Capillary ...
Electro-Oxidation of Methanol on Pt-Ru Nanostructured Catalysts Electrodeposited onto Electroactivated Carbon Fiber Materials
(Wiley VCH Verlag, 2010-02)
The surface of different carbon substrates, such as glassy carbon (GC), graphite cloth (GC-10), graphite felt (GF-S2), and carbon fiber paper (CFP) was modified by electrochemical treatment to generate high concentrations ...
Effect of Carbon-Based Particles on the Mechanical Behavior of Isotactic Poly(propylene)s
(Wiley-VCH Verlag GMBH, 2016)
Different carbon-based fillers such as carbon nanotubes (CNTs), graphite, and thermally reduced graphene oxide (TrGO) are melt mixed with an isotactic poly(propylene) (iPP) and the mechanical properties of the resulting ...
