Scientific Interests and Research-Related Skills

My main scientific interests are connected with the research of electrochemical reactions as well as electrodeposition and electrooxidation processes which occurs under abnormal conditions (high temperature, high vacuum, controlled composition atmosphere).

I have experience in the following fields:

- Electrodeposition of active elemental materials (silicon, germanium, hafnium, zirconium, vanadium, beryllium) from melted salts. Experience of electrooxidation in aqueous and molten salts media.

- Electrodeposition of thin metal films for corrosion protection.

- Development of metal chlorination processes with extension for use in semi-industrial environment.

- Electrochemistry of aqueous and non-aqueous solutions and halide melts. I have studied thermodynamic, kinetic and electrochemical properties of halide melts, containing hafnium, niobium, beryllium and vanadium by EMF (electro motive force) method, potentiometry, voltammetry in the galvanostatic regime, chronopotentiometry and in various conditions with the regulating and reversing current.

- Experience in investigating possible applications of molten salt media for technological purposes, including electroplating, refining, nuclear reactor fuels production and reprocessing.

- Experience in the classical methods of analysis, as well as several instrumental analytical techniques (Chromatography, XRD, ICP, Atom Adsorption Spectroscopy, Atom Emission Spectroscopy, SEM, EDS, etc.)

- Experience in development and construction of high-vacuum high-temperature apparatus for selective partitioning of metals (by simultaneous reduction reaction and vacuum distillation).

- Determination of corrosion resistance of stainless steels in high-temperature halide melts.

- Design, assembling and automatization of coulometric titration, oxygen permeability and impedance measurement setups. Characterization of ion-exchange membranes and SOFC cells.

- Service of microwave ovens for rapid sintering of oxide ceramics.

Skills in Equipment Development and Automatisation

I have experience in the design, construction and building-up of apparatus for high-temperature electrolysis, from laboratory to semi-industrial scale, including welding and machining of construction materials.

In 2008, in a laboratory of solid state electrochemistry in Aveiro, I have assembled a full automated setup for conductivity relaxation studies. I have experience in programming using C++ for scientific measurement systems, including parts by National Instruments, Quancom, Agilent, Eurothem, Yokogawa, Fluke, Eurotherm and Angelatoni Industrie.
