In a process they call ACDC, researchers expose plastic waste to around eight seconds of high-intensity alternating current, followed by the DC jolt. The products are high-quality turbostratic graphene, a valuable and soluble substance that can be used to enhance electronics, composites, concrete and other materials, and carbon oligomers, molecules that can be vented away from the graphene for use in other applications.

A team of researchers has developed a new way to control and measure atoms that are so close together no optical lens can distinguish them.
Scientists used photoacoustic spectroscopy applied to background-free analyses to measure unprecedentedly small trace gas concentrations.
