Tiny structures known as MXenes (IMAGE) University of Chicago Caption A scanning electron microscopy image reveals the beautiful shapes of tiny structures known as MXenes, which are of interest to scientists for new devices and electronics but were previously hard to create. These were grown with a new easier and less toxic method invented by chemists with the University of Chicago. For reference, the diameter of a human hair is about 50 µm.
