Developing new materials for the fusion reactor

Success in developing vanadium alloys strong at high temperatures

11-Dec-2018

In the future fusion reactor, plasma is confined by using the magnetic field inside the doughnut-shaped vacuum vessel. The blanket is in a location where it almost touches the plasma, and as if to enfold the plasma the blanket is placed on the inner surface of the vacuum chamber. The blanket, by ...

A potentially cheap, efficient and eco-friendly system for purifying natural gas

08-May-2018

Fundamental researchers at the Colorado School of Mines have proposed a novel two-part system for separating impurities from natural gas. Natural gas primarily contains methane, but impurities in the gaseous mixture need to be removed before the methane can be put into the pipeline. The newly ...
