‘Diamonds from the sky’ approach turns CO2 into valuable Carbon Nanofibers

Finding a technology to shift carbon dioxide, the most abundant anthropogenic greenhouse gas, from a climate change problem to a valuable commodity has long been a dream. Now, a team of chemists have developed a technology to economically convert CO2 directly into carbon nanofibers for industrial and consumer products. “Such nanofibers are used to make strong carbon composites, such as those used in the Boeing Dreamliner, as well as in high-end sports equipment, wind turbine blades and a host of other products.”

Previously, the researchers had made fertilizer and cement without emitting CO2. Licht calls his approach “diamonds from the sky...

New Horizons Discovers Flowing Ices on Pluto

 In the northern region of Pluto’s Sputnik Planum, swirl-shaped patterns of light and dark suggest that a surface layer of exotic ices has flowed around obstacles and into depressions, much like glaciers on Earth. Credits: NASA/JHUAPL/SwRI

NASA’s New Horizons mission has found evidence of exotic ices flowing across Pluto’s surface, at the left edge of its bright heart-shaped area. New close-up images from the spacecraft’s Long-Range Reconnaissance Imager (LORRI) reveal signs of recent geologic activity, something scientists hoped to find but didn’t expect. “We’ve only seen surfaces like this on active worlds like Earth and Mars,” said mission co-investigator John Spencer of SwRI.

The new close-up images show fascinating detail within the Texas-sized plain (Sputnik Planum) ...
