The Pressure Is On To Make Metallic Hydrogen
Scientists are getting close to turning hydrogen into a metal — both in liquid form and maybe even solid form. The rewards, if they pull it off, are worth the effort.
Scientists find a way to convert Carbon Dioxide from air into fuel
Researchers have discovered a process that takes Carbon Dioxide (CO2) from the air and converts it into methanol (CH3OH) with the help of a homogeneous catalyst.
Mini Carbon-Capturing Motors May Help Lower Carbon Dioxide Levels In The Oceans
To help address the growing problem of water pollution, a group of scientists have created tiny motors that can rapidly remove carbon dioxide from the water. Researchers have developed carbon-capturin...
