Fabrication of Amorphous Silver Nanowires by Helium Ion Beam Irradiation
Shehla, Ali A., Zongo S., Javed I, Ishaq A., Khizar H., Naseem S., Maaza M.Amorphous silver nanowires (a-Ag NWs) are fabricated from crystalline Ag NWs by using 5 MeV helium (He+) ion beam irradiation. At low dose (5×1015 ion/cm2), few defects are created in Ag NWs. As dose increases, more damage to the crystalline structure of Ag NWs is observed. Finally at high dose...

Highlighting of a local non-equilibrium thermodynamics during the transfer of trichlorethylene (TCE) in the superficial layers of arid soils
Samuel Ouoba, Bruno Cousin, David Y. Toguyeni, Salifou K. Ouiminga, Fabien Cherblanc, Jean Koulidiati & Jean-Claude BénetIn this paper, we analyse and model the mass transfer of trichloroethylene in the surface layer of soil. Our study essentially focuses on arid soils taking into account the phase change liquid–vapour. We have then examined the validity of the assumption of local equilibrium by comparing the...

Spectroscopic study of the system 2Σ→ 2π of OHradical and determination of the rotational temperatures by using a numerical model
Samuel Ouoba, Tizane Daho, Arsène H. Yonli, Jean KoulidiatiWe develop in this note a simple and practical method for the determination of the rotational temperatures based on the observation of molecular bands produced by the OH-radical. For this, we make an approach based on the concept of thermodynamic equilibrium and we proceed to a detailed study of...

Influence of Ambient Pressure on the Evaporation of Volatile Organic Pollutants (VOP) during Soil Decontamination: Case of the Trichloroethylene (TCE)
Samuel Ouoba, Salifou K. Ouiminga, Justin Zaida, Bruno Cousin, Moussa Sougoti, Jean KoulidiatiThis article presents the results on the volatilization of the volatile organic pollutants (VOP) during decontamination process from the soil. The choice of TCE as a volatile organic pollutant is explained by the fact that it is relatively highly soluble in water, compared to other compounds,...
