Effects of carbonate on the electrolytic removal of ammonia and urea from urine with thermally prepared IrO2 electrodes

Christos Comninellis, Agnieszka Kapalka, Véronique Amstutz, Kai Udert

Recent studies have shown that electrolysis can be an efficient process for nitrogen removal from urine. These studies have been conducted with urea solutions or fresh urine, but urine collected in NoMix toilets and urinals has a substantially different co ...

Voltammetric determination of extreme standard Gibbs ion transfer energy

Hubert Girault, Astrid Johana Olaya Avendano, Fernando Cortes Salazar, Manuel Alejandro Méndez Agudelo

A voltammetric methodology to determine the standard Gibbs energy of transfer of highly hydrophobic and hydrophilic ions has been developed. The electrochemical cell used includes a water|1,2-dichloroethane micro-interface supported on a microhole in a thi ...

Thermal management of the molten carbonate fuel cell plane

Danilo Marra

The operating temperature range of molten carbonate fuel cells (MCFCs) is about 925-955K. An input gas temperature of at least 855 K is necessary to guarantee good ionic conduction inside the cells. Maximum local temperatures higher than 960 K should be av ...

Electrochemical Investigation of the O-2(g),Ni/YSZ System Using Cyclic Voltammetry

Christos Comninellis, Cyril Falgairette

Cyclic voltammetry was used for the electrochemical study of a Ni thin film (similar to 880 nm) deposited on an yttria-stabilized zirconia (YSZ) solid electrolyte pellet at temperatures between 350 and 450 degrees C at 20 kPa O-2 and atmospheric pressure. ...

Adsorption of Superplasticizers on a Model Powder

Paul Bowen, Yves Houst, François Perche

Adsorption isotherms of carboxylate type superplasticizers with different architectures have been measured on MgO considered as a non-reactive model powder. This system allowed us to study the influence of pH, electrolyte type, concentration and ionic stre ...

Metallic supporting grid for ultrathin electrolyte membranes in solid oxide fuel cells

Paul Muralt, Samuel Rey-Mermet

A solid oxide fuel cell structure obtainable by selective electrochemical processing, comprising an electrolyte membrane (4) formed by a thin film more than 50nm but less than l0[mu]m thick, covering a supporting structure (1) made of a bulk substrate, the ...

ELECTROWETTING Shake, rattle and roll

Hubert Girault

A comprehensive theoretical basis for understanding electrowetting is now available. It shows that it is possible to effect drastic shape changes in electrolyte droplets immersed in another (immiscible) electrolyte. ...

A systematic characterization method for gravity-feed micro-hole drilling in glass with spark assisted chemical engraving (SACE)

Hannes Bleuler, Rolf Wüthrich, Ulrich Spälter

Gravity-feed drilling is the most commonly used method for micro-hole drilling in glass with spark assisted chemical engraving (SACE). This paper proposes a method allowing the systematic characterization of this drilling method. The influences of voltage, ...
