Laser-induced Shock Wave Crystallization of Nitrate Salts

Project: Research

Project Details


We propose the development of a pulsed nanosecond laser-based system to crystalize small crystals of nitrate salts by focusing the laser beam into under-saturated and saturated nitrate salts solutions. The laser-induced crystallization mechanism is based on the generation of shock waves by either direct hit of laser pulses into the solution or indirectly by hitting a small metallic object to generate shock waves without any photochemical intervention. The laser pulses used will be of either linearly or circularly polarized light to study the effect of polarization on produced crystals. The yielded small crystals, ranging from nanometer to micrometer in size, will be characterized using different techniques, namely; optical rotatory dispersion (ORD), x-ray diffraction (XRD) as well as scanning electron microscope (SEM). Simultaneously, a mathematical model will be developed to predict nucleation rate, crystals size and nature of produced crystals and for both crystallization methods. Lastly, a comparison will be drawn between the experimental and the theoretical results. This study, upon completion is expected to have positive effect on wide spectrum of research fields and industrial applications by allowing the production of small crystals that are difficult to form in traditional crystallization methods.
