The thesis aims are: 1) to develop a comprehensive understanding of the chemical and structural evolution of these materials under operating conditions using a combination of thermodynamic, crystallographic and electrochemical techniques
2) to explore the nature of non-stoichiometry and structural disorder in the cathode materials and correlate these properties with battery performance 3) to propose and synthesise novel battery cathode compositions which optimise power and energy density and materials cost 4) to understand and optimise sodiation and desodiation mechanisms in the anode.
It is an ecological technology based on an innovative system that combines electrochemical techniques
with UV irradiation allows an economic saving of between 70% and 100% of water and up to 100% of salt, besides being respectful with the environment.
Advances in Electrochemical Techniques
for Corrosion Monitoring and Laboratory Corrosion Measurements
New types of membranes might help; electrochemical techniques
may also help to make brackish water useful for irrigation.
When the literature is analyzed, there are many analytically defined methods that are listed in Table 1 for the determination of nitrite such as titrimetric , spectroscopic [17-22], chromatographic [23-25] and electrochemical techniques
[10, 15, 26-30].
The present study deals with the treatment of textile effluent using electrochemical techniques
on pilot scale (70 L).
The course, now in its 22nd year, will cover the fundamentals of corrosion and various electrochemical techniques
. Lectures and laboratories will be used to illustrate how electrochemical techniques
are applied, when they should be used, and how the various techniques can be integrated to solve complex problems.
As a consequence, several electrochemical techniques
have been adapted to be applied to tribocorrosion research.
However, recently, alternative strategies of characterization have been established, based on advanced electrochemical techniques
, which allow improving the electroanalytical properties of the sensor electrode by means of the optimization of the biocomposite composition based on carbon materials (as conductive phase) [22,23].
The study was carried out using various electrochemical techniques
. These methods included the use of potentiodynamic cyclic polarization, open-circuit potential, impedance spectroscopy, and the change of the potentiostatic current with time at 0.150 V (Ag/AgCl).
The performance of the inhibitors was evaluated by two types of electrochemical techniques
, namely, real-time corrosion measurements and potentiodynamic polarization curves.
The teams constructed pathogen sensors for measuring Escherichia coli in hydroponics systems using either electrochemical techniques
or gold nanoparticle (optical) transduction.
