Inexpensive, Non-Toxic Nanofluid Could Be a Game-Changer for Oil Recovery

Source: University of Houston

Researchers from the University of Houston have demonstrated that an inexpensive and non-toxic nanofluid can be used to efficiently recover even heavy oil with high viscosity from reservoirs. The nanofluid, made in a common household blender using commercially available sodium, allowed for recovery in lab tests of 80% of extra-heavy oil with a viscosity of more than 400,000 centipoise at room temperature.

Meteorites Show Transport of Material in Early Solar System

Source: University of California – Davis

New studies of a rare type of meteorite show that material from close to the sun reached the outer solar system even as the planet Jupiter cleared a gap in the disk of dust and gas from which the planets formed. The results, published this week in Proceedings of the National Academy of Sciences, add to an emerging understanding of how our solar system formed and how planets form around other stars.
