College of Science / University of Kerbala had discussed the M.A thesis which is entitled “Spectroscopic Characteristics Analysis of Silver/ colloidal solutions prepared Using pulsed Laser Ablation in liquid technique”. The thesis, which has been presented by Ruqayya Khadir Salman, aims at understanding the effect of laser variables, such as wavelength, energy, and pulse number, on characteristics of prepared particles, as well as to evaluate their stability over time.
The thesis demonstrates that the technique used has proven effective and safe in producing pure nanoparticles without chemical additives. The color change of solution was linked to particle concentration, and spectral analysis confirmed the stability of the plasmonic peaks.
The thesis emphasizes monitoring stability of these nanostructures through longer-term tests and advanced analyses to reveal their surface properties, as well as evaluating their antibacterial activity and potential applications in medicine and the environment.
