New copper catalyst could close the carbon cycle, making ethanol from atmospheric CO2

New copper catalyst could close the carbon cycle, making ethanol from atmospheric CO2 In a quest to find a way to convert carbon dioxide into something useful, researchers from Oak Ridge National Labs in TN stumbled across an inexpensive, room-temperature catalyst for turning CO2 into ethanol.The new catalyst is made of copper nanoparticles, electroplated onto a substrate of vapor-deposited, nitrogen-doped graphene nanospikes, all atop a slice of n-type silicon semiconductor.

Nanotubes rear their tiny heads again, this time as a stamp for electronic inks

Nanotubes rear their tiny heads again, this time as a stamp for electronic inks A team at MIT has developed a high-tech stamping process that involves a “forest” of carbon nanotubes, capable of printing electronic inks onto almost any surface, whether rigid or flexible.When densely packed, nanotubes can act as nanoscale print heads for electronic inks.
