Look what I found - A 'Nano-beach'

This image originally appeared in the 2015 Research student photography and image competition held to celebrate National Science Week (Aug 15-23). Blurb: It is amazing to image the nanostructured silver metallic films using scanning electron microscope (SEM) for the characterization. But I would say it really is a challenge. While I was expecting the same patterns of nano island structures, look what I found one day! A nano-beach - full of lovely waves, shining sands along the shore and of course some sea corals. It’s always been one of my habits to write my name on sands whenever I went to beach. I am even happier today because I could write my name on this nano-beach too. How amazing the life is…How fascinating would this beach be with some surfers
