Scientists can make and manipulate nanoscale objects with greater precision, but the imagery for examining these objects is black-and-white. Until recently, scientists have not comprehended atomic-microscopy equivalent to color and how nanoscale chemistry reacts with light. However, a new microscopy tool from the Department of Energy […]
