Electrodeposition of gallium and zinc onto aluminium. Influence of the electrodeposited metals on the activation process
(Elsevier Science Sa, 2007-04-11)
The electrodeposition of gallium and/or zinc on aluminium, aluminium–zinc alloy and vitreous carbon electrodes in chloride solutions is analysed. The electrodissolution of the formed interfaces is also described and ...
Characterisation of polypyrrole electrosynthesised on aluminium
(Pergamon-Elsevier Science Ltd, 2004-11)
Cyclic voltammetry has been used to investigate the role of the anions and the solution pH on the redox properties of polypyrrole electrosynthesised onto aluminium in alkaline solutions. The polymer film was characterised ...
Síntese de hidroxiuretanas livres de isocianato via fixação de co2
(Universidade Tecnológica Federal do ParanáToledoBrasilPrograma de Pós-Graduação em Processos Químicos e BiotecnológicosUTFPR, 2021-06-30)
In order to seek alternative ways to mitigate the environmental impacts generated by CO2 emissions, one of the solutions is to develop processes that use this gas as raw material, enabling physical, chemical and biochemical ...

(Universidad de Chile, 2019)
Desde hace unas décadas, los nanomateriales han captado la atención de los
investigadores alrededor del mundo, debido a sus diversas propiedades y
aplicaciones. la mayoría de los nanomateriales utilizados están basados ...
Approaches for multicopper oxidases in the design of electrochemical sensors for analytical applications
(PERGAMON-ELSEVIER SCIENCE LTD, 2010)
We report an effective approach for the construction of a biomimetic sensor of multicopper oxidases by immobilizing a cyclic-tetrameric copper(II) species, containing the ligand (4-imidazolyl)ethylene-2-amino-1-ethylpyridine ...
Bringing High-Rate, CO2-Based Microbial Electrosynthesis Closer to Practical Implementation through Improved Electrode Design and Operating Conditions
(American Chemical Society, 2016-01)
The enhancement of microbial electrosynthesis (MES) of acetate from CO2 to performance levels that could potentially support practical implementations of the technology must go through the optimization of key design and ...
(CO2 + 2-propanol) mixture as a foaming agent for polystyrene: A simple thermodynamic model for the high pressure VLE-phase diagrams taking into account the foam vitrification
(John Wiley & Sons Inc, 2007-05)
The equation of state model developed by Lacombe and Sanchez (J Phys Chem 1976, 80, 2352) is used in the form proposed later by Sanchez and Stone (Polymer Blends, Vol. 1: Formulation, 2000; Chapter 2) to correlate experimental ...
Desenvolvimento de Magnésia Cáustica para Revestimento de Aço Elétrico
(Universidade Federal de São CarlosUFSCarCâmpus São CarlosEngenharia de Materiais - EMa, 2021-01-05)
Electric steels are ferrous alloys with up to 3.5 wt.% Silicon in its composition, and with carbon concentrations around 20 ppm. They are materials with excellent magnetic properties, generally used in the manufacture of ...
Evaluación de mezclas pt-ru/c como catalizadores de la electro-oxidación de etanol
(Universidad Nacional de Colombia - Facultad de Ingeniería, 2004)
En este trabajo se estudia, mediante la técnica de voltametría cíclica, la oxidación electr-catalítica de etanol en soluciones de ácido sulfúrico a diferentes temperaturas y concentraciones utilizando como catalizadores ...
Obtenção e caracterização de membranas de Pd-Ni obtidas por eletrodeposição
(Universidade Estadual Paulista (Unesp), 2016-12-09)
Hydrogen consists in a valuable substance, largely used in the world, reaching the order of 5 billion cubic meters per year. Considered a clean fuel, since it generates only water in its combustion, this gas, when in the ...
