Biography

Hanan Talal Rahal has completed her Masters Studies in physical chemistry from Beirut Arab University in 2013 where she worked as a lab assistant at the department of chemistry. Currently, she is working on her PhD thesis since May 2015. Her research interest is to prepare different (Bi, Pb)-2223 superconductors and estimate the influence of the incorporation of different percentages of SnO2 and NiO nanoparticles on the electrochemical, mechanical and corrosion behaviour of (Bi, Pb)-2223 phase superconductors in different media.

M.SC. Thesis Title:  

 " Studies on the Inhibition of the Acidic Corrosion of Steel by Some Nitrogen Containing Compounds "

This work was conducted to explore the influence of thiourea and thiobarbituric acid on the inhibition mechanism of corrosion of mild steel in hydrochloric and nitric acids .

Ph.D. Thesis Title:   

" Study of the effect of nanoscale materials addition on the corrosion behaviour and mechanical properties of (Bi, Pb)-2223 Phase"

Superconductors are currently used in several domains including medical diagnosis (MRI-NMR), Power stations, Electronics chips, generators and motors as well as Maglev trains. Their discovery was one of the major developments in material sciences during the 1980's. Most of the studies on these materials concern their unique electric and magnetic properties that made them the promising candidates for technological applications. However, in the course of their becoming the basis for applications and devices, other properties of these materials must be characterized and optimized. These include mechanical properties, such as strength and hardness, as well as chemical properties, in particular resistance to corrosion and weathering. These latter properties have an important role in determining the suitability of these materials for various potential applications and the extent of the need for protective measures in each case. These properties are also important in view of the limitations which they impose the use of superconductors in various processing techniques.
Therefore, examining the corrosion of superconductors and ceramic materials is a need to preserve their durability and superconductivity properties
