NMR Quench
Our 500 MHz NMR machine quenched itself today
Here is an awful quality photo I took of the aftermath.


To make things worse, our other machine (300 MHz one) has been out of action since late last year, so we now have no NMR access whatsoever … for any non-chemists out there, this is bad, VERY bad!
MRI Quenching
I did some YouTubing and found this video of an MRI machine quenching itself (MRI and NMR are very similar instruments).

Liquid Helium
The NMR machine was full of liquid helium. The quenching involved the liquid helium evaporating very rapidly. Here’s a video about the properties of liquid helium and a video of a liquid helium fountain.

Brooker Bunch and visitors
We’ve had quite a few visitors to the Brooker Bunch research group recently including Jane Nelson and Grace Morgan. This photo was taken facing away from the University of Otago Chemistry Department. From left: Jane Nelson, Grace Morgan, Humphrey Feltam, Ryan Hellyer, Jonathan Kitchen, Andy Noble, Owen Clements, Sally Brooker, Nick White and Scott Cameron.

Lehn Stock photos
The poster presentation at Lehn Stock 2007 was a good chance to network with chemists from other parts of the country.
A rather stunned looking Matt Polson walking in front of my attempt to take a photo of the Steel group from Canterbury. Matt used to be lab demonstrator many moons ago.

Lehn Stock
I attended the Dunedin Supramolecular symposium and presented my poster on mixed cobalt(III)/silver(I) coordination complexes. The star of the show was Nobel prize laureate Jean Marie Lehn who spoke about his pioneering work in the area of supramolecular chemistry.
From the Supramolecular chemistry Wikipedia page : “Supramolecular chemistry refers to the area of chemistry which focuses on the noncovalent bondinghydrogen bonding, metal coordination, hydrophobic forces, van der Waals forces, pi-pi interactions, and/or electrostatic effects to assemble molecules into multimolecular complexes.
Iron(VI)
Karl Wieghardt was visiting the Brooker Bunch and whilst here he found out he’d made the worlds first iron(VI) compound! While celebrating at Eureka, Sally arranged this cake with six silver candles to represent his new discovery.
For any of you non-chemists, discovering iron(VI) is pretty huge! Iron is almost always found in the +2 and +3 states so 6+ is completely nuts! There’s some more information about it here … http://www.news.wisc.edu/12636
