A colorful schematic of an exciton surfing on a red and blue wave graph. A yellow and blue isometric view of molecules is below. The purple/blue solution contains crystals of the berkelocene “sandwich.” Silica nanoparticles affixed with a distribution of polystyrene chains (purple) self-assemble into hexagonal lattices. Depending on how the chains are organized on the particle surface, they tangle together (purple) or unravel (blue) when compressed. Dozens of droplets clustered together Roughly diamond-shaped asteroid with a rocky, uneven surface, set against a completely black background. Two researchers in blue coats and safety glasses look at an experimental setup. Elemental mapping of Pd/COF confirming uniform Pd distribution. Graphic illustration of molecules floating with cinema tape against a dark background. A rendering in paraview of the product of the 3D reconstruction. (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.
