In the present work, Iranian natural zeolite particles (NZ) as an abundant and low-cost resource were modified by chemical covalent attachments of commercially available stearic acid (SA) with tunable hydrophobic/hydrophilic properties. The versatile, simple, and green technique of mechanogriding was performed for the hydrophobic derivatisation of NZ. The NZ and as-prepared modified particles w...

A novel intracavity laser diagnostic has been developed to perform quantitative two-dimensional imaging of major species and temperature by using spontaneous Raman scattering and Rayleigh scattering in a turbulent flame. A flash-lamp-pumped dye laser cavity is modified to include sheet-forming optics and 100% reflecting end mirrors. In a comparison of this system with a laser configuration with...
