The aim of this paper is to study the effects of carbonation on the electrochemical properties of carbon steel and galvanized steel, immersed into cubic prisms of concrete elaborated with Portland pozzolanic cement. ...

Nanomaterials produced from different carbonization methods and using different biomasses have been developed as fertilizers for soil. The preparation of nanomaterials through processes that use less chemical reagents and ...

We report the highly selective and sensitive voltammetric dopamine quantification in the presence of ascorbic acid and serotonin by using glassy carbon electrodes modified with a dispersion of multiwall carbon nanotubes ...

We report the analytical performance of glassy carbon electrodes (GCE) modified with a dispersion of multi-wall carbon nanotubes (MWCNT) in polylysine (Plys) (GCE/MWCNT-Plys). The resulting electrodes show an excellent ...

This thesis is divided in two chapters. The first chapter entitled 'The Dynamics of the Dynamic Hedging' derives an optimal hedging ratio in a dynamic discrete-time stochastic setting allowing for margin requirements. Then, ...

This work is focused on the critical analysis of the influence of the experimental conditions on the efficient dispersion of hollow-type (hMWCNT) and bamboo-like (bMWCNT) multiwall carbon nanotubes with polyethyleneimine ...

This work reports the advantages of using glassy carbon electrodes modified with multiwall carbon nanotubes (MWCNT) dispersed in polyethylenimine (PEI). The presence of MWCNTs wrapped by PEI largely facilitated the strong ...

Our objective was to estimate the impact of harvesting stover from agricultural crops to generate biofuels or electricity on the soil organic carbon levels of the Pampean Region in Argentina. For this purpose, a carbon ...
