    Abstract: To increase heavy oil conversion by hydrocracking, the larger pore opening mesoporous materials with enhanced acidity and hydrothermal stability are required. A series of mesoporous Al-SBA-15 was studied in acid-free and different HCl concentration solutions with various initial SiO2/Al2O3 molar ratio. The final product samples were characterized w...

    Abstract: The study investigated cutting of glass by non-laser ablation technique through non-linear absorption laser pulses induced optical breakdown, melting and plasma expansion throughout the glass thickness from bottom to top. Picosecond near-infrared laser pulses were used. The laser beam was focused with an objective lens with numerical aperture (NA) ... Show More
