PSU geologists and microbiologists have patented a way to protect dams from destruction at high concentrations of methane at their base. The new method will improve the safety of the operation of those dams dependent on sandy and clay soils.

Oscar Fattalov, a post-graduate student in Physics, explores the phenomenon of bubbles causing effect on the solid surface, as a result of ultrasound affecting the liquid layer underneath. The experiments will expand the fundamental knowledge in the field of hydrodynamics, acoustics and sonochemistry. The results can be applied to improve existing technologies for mineral processing using the flotation method.
