Salamandra
Feeling a bit fed up with those black-and-white SEM images, today it's time to color up!!!
I'm not so sure if anyone else sees a salamandra in this pic (I do!), in fact it's a leftover of the PMMA layer.
PMMA is a special kind of resist which we use for electron beam lithography. In this resist we can 'draw' shapes and lines with the electron beam and then fill them with metal, so they stay forever on the chip (like the small cross in the left corner of the pic). The PMMA should go away with acetone, but sometimes it leaves some stains and residues, just like on this sample.
No. 3 on the list http://de10.com.mx/13048.html :)
Silicon Fan
To mark our silicon chips we make a scratch with a diamond tip. Then in the region of the scratch we can sometimes find some pretty structures, just like this one. It reminds a little bit of a Spanish fan, the typical female accessory here, even in 21st century!
Technarte, Bilbao
I think I'm obsessed with all this art thing!!Maybe that why I got so excited after seeing the info about the Technarte conference in Bilbao. It's all about art and technology, bringing together artists, researcher, professors and so on.. It might be an exciting event, see more on http://www.technarte.org/en/index.php

Today my discoveries were limited to watching pictures. Normally the scientific pictures are taken by scientists in a science lab (wow)But now, you take a retired schoolteacher, convert his garage into a lab and what comes out wins the Royal Photographic Society's medal. Simple, isn't it?
Enjoy the prize-winning pictures in today's Guardian.
