The electrochemical properties of imidazol-linked iron phthalocyanine—carbon electrodes
Electrodes for the electrochemical reduction of oxygen have been studied galvanostatically. The electrodes were of the activated carbon-polymeric iron phthalocyanine (FePc) type, made hydrophobic with a Teflon...

X-ray photoelectron spectra and electrochemical properties of imidazol-linked iron phthalocyanine carbon electrode systems
Electrodes for the electrochemical reduction of oxygen have been studied both galvanostatically and by XPS and IR spectroscopy. The electrodes contain a polymeric phthalocyanine catalyst fixed to an activated ...

Chemically regenerative redox fuel cells. I Membrane studies
Three different types of membrane have been tested in a chemically regenerative redox fuel cell. It was found that a Nafion membrane gave the best polarization curves, but also that a much cheaper silica-fille...

On the isokinetic effect for reactions of carbon dioxide with metal surfaces
Kinetics data for the reaction CO2(g)→ CO(g)+O(ads) at metal surfaces are used to illustrate a previously developed model for the isokinetic effect. From this, it is concluded that the bending mode of an adsorbed...

The Influence of DLC Coating on EHL Friction Coefficient
High hardness, high elastic modulus, low friction characteristics, high wear and corrosion resistance, chemical inertness, and thermal stability are factors that make diamond-like carbon (DLC) coatings the sub...

Open AccessThe Effect of DLC Coating Thickness on Elstohydrodynamic Friction
The application of surface coatings has been shown to reduce friction in elastohydrodynamic lubrication (EHL), not only in the mixed and boundary regime when asperity interactions occur, but also in the full f...

Open AccessMonitoring of Running-in of an EHL Contact Using Contact Impedance
Running-in is an important process for elasto-hydrodynamic lubricated contacts, which affect both service life and operating performance. However, the possibilities of monitoring running-in are still poor. The...

Open AccessAbsolute Measurement of Elastic Waves Excited by Hertzian Contacts in Boundary Restricted Systems
In most applied monitoring investigations using acoustic emission, measurements are carried out relatively, even though that limits the use of the extracted information. The authors believe acoustic emission m...
