Anodized Aluminum Oxide (AAO) nano-templates were made through two step anodization process of aluminum sheet in two electrodes electrochemical cell. Controlling of the structural properties of pores template achieved by a fine adjusting of some parameters of the electrochemical process includes, type, concentration, and temperature. Then the fabricated nano-template subjected to post electrodeposition of nanometalic substances of , Ag ,Au, Cu, and Pt from their freshly prepared salts ligand complexes. All prepared templates were subjected to intensive surface structure analysis by AFM, SEM, and XRD a detailed information on pore shape , pore size distribution , and crystal types were estimated .

The research is significant with regards to the understanding of the physics of iron oxide (IO) nanoparticles and graphene-IO composites and their applications in medicine. The effect of nucleation and growth of Fe3O4/Gamma-Fe2O3 nanocrystals within biomolecular templates, on the magneto-structural properties and their implications in MRI contrast and heat generation in magnetic hyperthermia has been extensively studied. The research tries to address the issues relating to the uniformity in particle size, shape, distribution, and effective functionalization. By choosing different templates the mutual interaction between adjacent particles could be tuned which was found to have a profound impact on the magnetic anisotropy of such systems. Future work would concentrate on the self assembly of such systems whereby the anisotropy can or is expected to be modulated to achieve enhanced diagnostic and therapeutic value in killing cancer cells. The work follows an integrated approach and covers the entire spectrum of materials development (synthesis by mimicking nature-biomineralization), applications (MRI and magnetic hyperthermia) and simulation (bioheat model using COMSOL).

Quantitative TEM Study of Nitride Semiconductors

The theoretical part of this work is dedicated to the adaptation of high-resolution transmission electron microscopy for studying III-nitride semiconductors. First, the principle of heterostructure composition evaluation by means of atomic displacement measurement is stated. The comparison of two strain measurement techniques, geometric phase analysis and projection method, is then presented. Finally, the effects of acquisition conditions on the strain measurements were elaborated. The experimental part of this work is dedicated to the characterization of GaN quantum dots (QDs) grown on AlGaN templates. This study revealed several phenomena original for nitride semiconductors. The surface QD shape depends on the GaN layer thickness, whereas the buried QD shape and volume are influenced by the QD capping. Moreover, a phase separation occurs in the AlGaN barriers. To explain the observed phenomena, various models founded on the principle of total energy minimization have been developed. Several approaches, based on the results of this study and aimed for the improvement of the optoelectronic devices properties, are also proposed.

Deep drawing process is an important industrial processes where it has been extensively used. It is a process for converting the blank metal to make cylindrical shape in most of the cases. A research program for performing basic calculations related to the product shape was utilized. Eighteen geometric shapes have been selected for the production in this process. The program is include the general equations for this controlling process for each form. When choosing one of the shapes in the program, the dimensions of the desired product are selected. In other words, the inputs to the program are the required dimensions of the product before reaching the required deportation. In addition, diameter, height and other related dimension are computed which were chosen for each stage throughout the operation. Computer program is aimed to help designers templates deep drawing quickly through the implementation of the process, and this exceeds the designer experience that is required to perform the require calculations.
