Furthermore, frequency-dependent elastic parameters were used to define a dispersion factor for fluid prediction in thin sandstone reservoirs. The novelty of the study is that the proposed approach ...

Scanning electron microscopy was used to observe microstructural changes in the sandstone. After analysis, the evolution of the internal structure of Tongxin sandstone with heat treatment is ...

To do this, the team subjected a reactive medium to a hyperbolic flow, a type of fluid flow in which fluid elements are stretched in one direction and compressed in another. "We first prepared ...

New Hubble Space Telescope images of a black hole-powered quasar reveal 'weird' structures and gigantic jets of energy that scientists are just beginning to explain. Nearly 35 years after its ...

Bach, Nyman and the rest of the research team made several new tetraperoxo titanate structures -- a titanium atom coordinated with four peroxide groups -- that showed varying abilities to scrub ...
