colinbm Posted July 5, 2015 Share Posted July 5, 2015 My adult sons are interested in advancing their careers into nano technology & nano robotics.I was watching this really interesting doco on nano technology & robotics, it covers a vast array of topics briefly.There are too many wows & WTF moments.This one at 36 minutes was a gob smacker for me.I had known that coloured glass filters were an alchemists dream of glassmaking secrets, but this one took the cake & it is over a thousand years old. Stained glass windows............ Element, size, shape & temperature, all go together to decide the colour the glass takes on......just brilliant !I have to know more.........Structural Colour.CheersCol Link to comment
Andrea B. Posted July 5, 2015 Share Posted July 5, 2015 Col, excellent find. Thanks for the link. Link to comment
rfcurry Posted July 5, 2015 Share Posted July 5, 2015 Col, Interesting find. That use of nanoparticles is the basis for my patent on camouflage in the ultraviolet spectrum. see http://uvrdefensetech.com/index.php?homeBy using different ceramic oxide nanoparticles, usually in the range of 10-40nm in diameter, in a very thin film, our nanocompounds can reflect the percentage of UV that we want -- 7%, 22%, or 80%, while remaining transparent to visible light and NIR.

colinbm Posted July 8, 2015 Author Share Posted July 8, 2015 Thanks Andrea & ReedLooking a bit more at 'structural colour'.....http://www.australasianscience.com.au/article/issue-march-2014/refracted-brilliance-how-nature%E2%80%99s-structures-produce-colour.htmlCheersCol Link to comment
colinbm Posted July 8, 2015 Author Share Posted July 8, 2015 Some more 'structural colour'.....http://aob.oxfordjou...6/1141.full.pdf http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2850791/ Link to comment
Andrea B. Posted July 11, 2015 Share Posted July 11, 2015 Very interesting paper about structural colour and iridescence! The most spectacular examples Bjørn and I found on the Desert Wildflower Safari were the various desert poppies (eschscholzia species). Their iridescence caused them to "wink" black and white - almost like signaling with shiny metal or a mirror. **** Reed, interesting about your patent! Link to comment
