Amino Acids as Corrosion Inhibitors for Carbon Steel in Saline Solution

   The present research involves potentiostatic investigation of the corrosion behavior of carbon steel alloy in saline (3.5% NaCl) solution.The general pattern and the experimental techniques used could be
classified into three different aspects as follows:
1. The corrosion behavior of carbon steel specimen in saline solution (blank) and in the presence of inhibitors (Val, Ser, Trp and Lys) at pH (2 and 11) with various temperatures ranging between (293313)K from the polarization curves over a range of potentials (700to-300)volt.


New photostabilizers for poly(vinyl chloride) based on some metal comlexes of 2-(6- methoxynaphthalen-2-yl) propanoate

The preparation of Bis[2-(6-methoxynaphthalen-2-yl)propanoate] chelate complexes with nickel(II), copper(II), zinc(II), cadmium(II) and tin(II)  were described in this thesis.Infrared, ultraviolet–visible, spectrophotometric techniques, magnetic susceptibility, atomic absorption, conductivity measurements and melting point were used to characterize the free ligand and the above chelate complexes. All these


Electrochemical Studies At Room Temperature Ionic Liquid Of Choline Chloride/ Tartaric Acid

      The oxidation-reduction behavior of the newly prepared choline chloride/d-tartaric acid ionic liquid was studied by electrolysis at 25°C to 95°C with applied voltages of 0.5 to 5 volts. This ionic liquid was found stable up to 45°C and 5 volts as only showed small changes in current density. But, at 65°C the liquid showed noticeable unstable behavior particularly at or above 2.5 volt, which increased at higher temperature with increase conducting too.
