College of Science, Kirkuk University discussed a master's dissertation on using of pulsed LASER ablation to prepare Nano-Particles from two materials and investigated the effect of changing the mixing ratio on their properties by the postgraduate student, Ms. Fatima Mu'ayyad Ahmed.

The dissertation aimed at producing Nano-Particles from cobalt and nickel sheets using pulsed LASER ablation and study the effect of laser parameters on the structural and optical properties of the particles in terms of shape, size and crystal structure using advanced analysis techniques, including X-ray diffraction (XRD) and atomic force microscopy (AFM) to analyze particle size and roughness rate and X-ray spectroscopy (EDX) analysis. 

The dissertation concluded that the TEM results shows a decrease in the sizes of the Nano-Particles, as the sizes of the cobalt Nano-Particles (CoNPs) ranged between 13-56 nm and the nickel nanoparticles (NiNPs) ranged between 15-64 nm, while the sizes of the Ni:Co NPs composite Nano-Particles were (20-79) nm.
