(Credit: David Raftrey) Two people in safety glasses observe a scientific experiment through a glass window in a lab, with equipment and handwritten notes visible inside the fume hood. Two researchers in lab coats and goggles work with outdoor scientific equipment near a modern building. This image shows the cobalt defect fabricated by the study team. The green and yellow circles are tungsten and sulfur atoms that make up a 2D tungsten disulfide sample. The dark blue circles on the surface are cobalt atoms. The lower-right area highlighted in blue-green is a hole previously occupied by a sulfur atom. The area highlighted in reddish-purple is a defect—a sulfur vacancy filled with a cobalt atom. The scanning tunneling microscope (gray) is using electric current (light blue) to measure the defect’s atomic-scale properties. Jen Wacker processes a sample of actinium at Berkeley Lab. Two smiling people in blue lab coats and safety glasses. The person on the right has their arm raised in the center of the frame presenting a nickel-sized sample. A woman, left, and a man look at visual data on several monitors with components of an electron microscope nearby.
