Scanning electron microscope images of NiP metallic glass nano-beach umbrellas with 'handles' of thickness ~100 nanometers and below. The tops are perfectly semi-spherical owing to the isotropic amorphous microstructure. When the tops get too big, the umbrellas get blown over. Image taken in an FEI Quanta SEM. Samples prepared by electroplating into a lithographic template; templates prepared with the help of Rachel Liontas.
