Over the past, I have provided high-level support in a variety of industries
and universities and across multiple functional areas: (Design chemical speciation
Python programs for dissolution and crystal growth of sparingly soluble
salts, processing thermal aging models for conducting polymers, electrochemistry,
synthesis of organic conducting polymers, crystallization, biological
mineralization & demineralization, formulation of nano-detergents
& microemulsions for application in lubricants).

I have a degree in Chemistry, two years of post graduate research background in advanced technology materials, also experience in preparing TiO2 nano-tubes under potentiostatic conditions for water splitting
and solar cells applications and experience in Hard X-rays: EXAFS & XANES
data analysis of  CaCO3 crystalline and amorphous polymorphs (estimating inter-atomic
distances between Ca, C, and O and their coordination numbers by parameterising the
EXAFS equation and by using the DEMETER package).

My scientific endeavours were first initiated in the field of Solid State Physics during my
postgraduate Diploma Thesis project entitled “Thermal aging of conducting polymers
doped with ZnO nanocrystals”. This was an exciting project and I worked towards the
synthesis of conducting organic polymers (Polyaniline and Polypyrrole) doped with
inorganic impurities (ZnO) which have many applications as substrates in photovoltaic
cells and batteries. Organic Photovoltaic (OPV) Cells have many advantages compared
with the traditional inorganic PV cells. We can refer the advantages of easy construction,
the low cost and that they are friendly to the environment.

I have also first-hand experience with the synthesis and characterization of biomaterials and the thermodynamic analyses of crystallization phenomena in biological conditions ( pH=7.4, Ionic
strength = 0.15 Mol/L and T = 37 degrees Celsius). The experiments were conducted under constant
supersaturation (precipitation) or undersaturation (dissolution), constant pH and temperature
(plethostatic conditions), in an attempt to elucidate the effects of additives
(water soluble polyelectrolytes, lipids) in the crystal growth rates and the morphology of
hydroxyapatite, and his metastable phases: (octacalcium phosphate, dicalcium phosphate
dihydrate, tricalcium phosphate, amorphous calcium phosphates).

On the other hand, I had the opportunity to study the rigorous transformation of vaterite (stabilized with
poly-electrolyte additives in the supersaturated CaCO3 working solutions) and aragonite (stabilized
with Mg2+) to calcite. However, there are also other forms of calcium carbonate
that include water in their chemical structure (CaCO3 · 1H2O and CaCO3 · 6H2O) that
unfortunately it is very difficult to be isolated. CaCO3 scale deposits play crucial role in
industrial applications and in the biomineralization (the process by which sea organisms
build their “hard parts”).

The process of learning is never – ending. As one goes on to learn new things
one realizes that there are many more things which one needs to learn to quench one’s
thirst of knowledge. During the course of post – graduate studies I have learnt many
things but have also realized that I need to learn more in order to advance the frontiers
in my field of interest. My plans are to continue working hard and to accomplish as much
as possible on studying new kinds of low voltage organic field effect transistors in order
to facilitate a detailed understanding of more sensitive detection methods and improved
investigation of traces of volatile organic chemicals.
