Atomic force microscopy investigations on nanoindentation impressions of some metals: effect of piling-up on hardness measurements
In the indentation test, the hardness and the elastic modulus depend strongly on the estimate of the indenter-material contact area at peak load. However, many elastic–plastic behaviours such as elastic recove...

High Reactivity of CH2 Radical in an AR–CH4 Post-Discharge
This work is devoted to the study of the reactivity of CH 2 radical in the post-discharge of an Ar–CH 4 microwave plasma. These radicals are selectively produced using the energy transfer reaction between argon ...

SrBi2Nb2O9 Ferroelectric Powders and Thin Films Prepared by Sol-Gel
Pure SrBi2Nb2O9 powders and thin films were obtained using sol-gel synthesis from mixtures of niobium ethoxide, bismuth and strontium 2-ethylhexanoates. Powders crystallized for 2 hours at 700°C had grain size...

Characterization of an argon-hydrogen microwave discharge used as an atomic hydrogen source. Effect of hydrogen dilution on the atomic hydrogen production
This work is devoted to the study of an argon-hydrogen microwave plasma used as an atomic hydrogen source. Our attention has focused on the effect of the hydrogen dilution in argon on atomic hydrogen productio...
