Electrochemical Transformation of Alkanes, Carbon Dioxide and Protons at Iron-Porphyrins and Iron-Sulfur Clusters
… chemical and electrocatalytic oxidation of hydrocarbons to alcohols and epoxides by using iron (III) porphyrins as catalysts. A series of new basket-handle thiolate Fe (III) porphyrins have been used to mediate anodic oxidation of hydrocarbons, specifically adamantane hydroxylation and …

Development of physical models for the mesoscopic simulation of gas-surface interactions
… (reactive) and molecular (non-reactive) with carbon surfaces: flat (vitreous) and complex porous microstructure (FiberForm®) at high temperatures ranging from 500 K to 2000 K. These models may be employed directly in conventional computational fluid dynamics (CFD), kinetic simulation, and …

Structure-Property Relationships of Tantalum Carbide Foams and Synthesis of an Interpenetrating Phase Composite
… within tantalum carbide (TaC)/reticulated vitreous carbon (RVC) foams as areal TaC density increased. All MCNP modeling runs predicted slightly higher neutron transmission than what was experimentally measured, potentially indicating that the foam structure had a small influence on neutron …

Otimização de um eletrodo de carbono vítreo modificado com nanotubos de carbono para detecção voltamétrica do fungicida carbendazim.
… new electrode materials, such as the glassy carbon, carbon paste, platinum, gold, among others, are excellent alternatives to the mercury electrode because of the ease of construction, wide potential window and low toxicity. Recently, new materials as carbon nanotubes have been used, so …

Design and synthesis of novel nanometallic catalysts and electrode materials for green fuel cells
… fabricated via electrodeposition on a glassy carbon electrode. The catalyst was tested in acidic media. The typical SEM images showed the near spherical Pt structures with diameters in a range of 50–120 nm. The general size of the PtCr nanoparticles were determined to be around 105 nm and the …
