Fixed Energy X-ray Absorption Voltammetry and Extended X-ray Absorption fine Structure of Ag nanoparticle electrodes

Christos Comninellis

FEXRAV (Fixed Energy X-ray Absorption Voltammetry) has been recently introduced as a powerful tool in electrochemistry. It consists in measuring the X-ray absorption coefficient at a fixed X-ray energy while the electrochemical potential of the material un ...

Role of sulfur in BaVS3 probed by S K-edge absorption spectroscopy

László Forró, Helmuth Berger

We show that the quasi-1D behavior of BaVS3 can be understood analyzing the X-ray absorption near edge spectra at the sulfur K edge. Linear dichroism experiments, analyzed with the help of ab initio calculations, reveal two strong and polarization dependen ...

Effect of surface pretreatment of TiO2 films on interfacial processes leading to bacterial inactivation in the dark and under light irradiation

César Pulgarin, Juan Kiwi, Michaël Bensimon, Sami Rtimi, Rosendo Sanjines, Jelena Nesic

Evidence is presented for radio-frequency plasma pretreatment enhancing the amount and adhesion of TiO2 sputtered on polyester (PES) and on polyethylene (PE) films. Pretreatment is necessary to attain a suitable TiO2 loading leading to an acceptable Escher ...

The effect of titania precursor on the morphology of prepared TiO2/MWCNT nanocomposite materials

László Forró, Arnaud Magrez, Endre Horvath, Klara Hernadi

Since materials science is of great importance, the application of composite materials based on carbon nanotubes (CNTs) is widely investigated. Current work is aimed at preparing nanocomposites of TiO2/MWCNT using an impregnation method combined with slow ...

Preparation and characterization of multiwalled carbon nanotube/In2O3 composites

László Forró, Arnaud Magrez, Klara Hernadi

We have prepared multiwalled carbon nanotube (MWCNT)/In2O3 composites using a simple impregnation method. The precursor compound indium(III) chloride (InCl3) was used to cover the surface of MWCNTs and distilled water was used as solvent. The applied mass ...
