A redox reaction has been used to move a molecular piston back and forth. It is hoped that this will allow nanomachines to make use of it.
The piston works with a man made molecule called a rotaxne. The rotaxne is a liner molecule with a napthalene complex at one end and sulfur containing group at the other end. The sliding part of the piston is made of six carbon rings, joined to form a hooped shaped positively charged ion.
When teaching about combustion, we must remember to consider ‘complete’ and ‘incomplete’ combustion.
During complete combustion, the fuel will produce CO2 and H2O.
Do you trust the temperature reading on your thermometer? How important is it to us that equipment records the ‘correct data’?
You may remember a few years ago (six and a half) that NASA landed a couple of robots on Mars – Opportunity and Spirit.
Tuesday was World Water Day 2011 and the theme for this year was ‘Water for Cities’. The theme for this weeks blogs posts will therefore be all about water.
So far, we have been focusing on the fact that water has a much higher boiling point than is predicted and that the reason could be pinned down to electronegativity.

You may also remember that yesterday I posted a question asking:
This week has been ‘National Science and Engineering’ week in the UK.
The BBC has come up with this quiz (click here)to see how much you know about science fact or fiction – I scored 5/8 and was pleasantly surprised to find my rating as being ‘Graduate Student’ – not quite ‘Professor Standard’ but a least I wasn’t a ‘lab rat’ ! 
You will have heard of the saying ‘like trying to find a needle in a haystack’ , well how about this one, ‘trying to find a single atom in a crystal’.
This phenomena has now been successfully carried out by a research team. Individual atoms of lanthanum have been observed in crystals of calcium titanate.
Those of you who have been reading this blog for a while may remember a few posts about twelve months ago that were linked in with a BBC TV series called ‘Wonders of The Solar System’. It was hosted by professor Brian Cox.
Well, the prof is back with a new four part series. Episode 2, Stardust aired Sunday evening in the UK.
Boric Acid is an element that has made its way into the limelight this weekend.
