Congratulations of Sarah and Rebecca, both graduating from the MPhy course. It was a pleasure to have you in the lab. Will you be back?

Sometimes, life can feel like you're stuck in the part of the training montage where nothing is going right. No matter how much you "wax on, wax off", the finish on Mr. Miyagi's car remains lacklustre. While Rocky Balboa can magically improve once the inspirational music gets to the chorus, we have to deal with, and learn from our mistakes in real time. This can be frustrating.
However, with enough time and perseverance, you can reach the end of the montage.
The Silicon lab is reopened.
As the building stage of the new Si lab chamber draws to a close, there is a final step - bakeout (info) - build an oven around your system and cook it for a few days. This process removes any water or pesky hydrocarbons inside the chamber.
As with anything in experimental physics, there are 2 ways of achieving bakeout: the expensive (or 'Graphene Centre') way, or the funny way.
And this is the most flattering angle.
Adrian Hooper kindly did his photographer bit yesterday and took some snaps of the group and the lab. Here they are. Be warned I have gone a wee bit OTT with some photo editing.
After about a year of hard work we finally have the Omicron LT-Q+ working at 77 K with a Q+ tip (albeit in STM mode). Here are some raw examples of the first images we have taken.
You can now, if you so desire, find me on:

Can you leave a molecular switch to its own devices? We expose the not-so-passive influence of a scanning tunnelling microscope tip on a molecular switch.
