Tuning a fundamental material property with an electronic coating

Researchers at the University of Southern California have developed a bilayer coating of an insulator and graphene on top of a semiconductor that can tune the energy required to eject electrons out of the material, potentially making electrochemical devices more efficient.

Interplay of free electrons: Tailored electron pulses for improved electron microscopy

Researchers at the Max Planck Institute for Multidisciplinary Sciences, Germany, resolved and analyzed the mutual repulsion between individual electrons in an electron microscope for the first time, enabling the team to develop a method that could increase the performance of established electron microscopes and open up a new interface between electron microscopy and quantum technology.

NASA’s Bennu asteroid sample contains carbon and water

Initial studies of the 4.5-billion-year-old asteroid Bennu sample collected in space and brought to Earth by NASA show evidence of high-carbon content and water, which together could indicate the building blocks of life on Earth may be found in the rock.
