A team of metallurgists and materials scientists at the Max-Planck-Institut für Eisenforschung GmbH has uncovered the reason for the sluggishness that occurs when attempting to use hydrogen instead of coke to make steel. ...
Poorly drained agricultural soils emit enough of the greenhouse gas nitrous oxide that the resulting climate change effects could far exceed the benefits of using the same soils as a means of sequestering carbon, according ...
