Sharon has just returned from a week at CEA Saclay in France, where she was lecturing (along with collaborator Jonathan Yates from Oxford) at a Winter School (entitled “Experiment and Modelling in Structural NMR”). The School involved lectures and workshops on experimental NMR and the use of DFT and modelling computer codes, and was attended by PhD students from across Europe.


John gave a computational chemistry seminar entitled “A Computational and Experimental Solid-State NMR Study of Selenium- (and Tellurium-) Containing Systems”, detailing his recent work with the group of Professor Derek Woollins.

We welcome three new members this month; Scott Sneddon who begins a PhD, and two undergraduates, Lauren and Olivia, who will be completing their research projects in the group. Lauren will be working with Daniel synthesising and studying paramagnetic MOFs, while Olivia will be working on the 17O enrichment of aluminophosphates using ionothermal synthesis.


John and Martin P spent time down at the 850 MHz Solid-State NMR Facility in Warwick this month. John carried out some 25Mg NMR, while Martin investigated 39K NMR of perovskites.


September 2011


Sharon has been named a member of the Royal Society of Edinburgh’s new Young Academy of Scotland. See here for the University Press release. The aim of the initiative is to stimulate creative ideas and collaborative working that will help address some of the key challenges facing Scotland and contribute to solving some of the global challenges facing the 21st century.


The group have recently returned from the 7th Alpine NMR Conference on Solid-State NMR in Chamonix, France. Sharon gave a talk at the meeting on collaborative work with Professor Russell Morris entitled “Solid-State NMR of an Ionothermally-Prepared 17O-Enriched Aluminophosphate”, while John, Martin M, Valerie, Daniel and Martin P presented posters.

Martin and Valerie presented posters on their work on pyrochlores and aluminophosphates, while Daniel gave his first conference talk entitled “Solid-State NMR Investigation of HKUST-1 and STAM-1”.



The group was joined this month by Maria Wieckhausen, a IAESTE student from Germany, who will be working on her eight week placement with us. Maria has just completed the second year of her five year undergraduate Masters degree in Germany. While in St Andrews Maria will be working alongside John on 125Te solid-state NMR of organotellurium compounds (in collaboration with the group of Professor Derek Woollins) and investigating the use of DFT for calculating Te NMR parameters.


Siobhan Day (who graduated from St Andrews this summer) has undertaken a summer project with Sharon and Dr Iain Smellie to develop new experiments for the RSC “Chembus” and the RSE “Chemical Cluedo” Masterclass. Siobhan did an excellent job and produced a whole range of new experiments for the schoolchildren to do this coming year.

Congratulations to Karen who graduated on 22nd June for her PhD! Despite the forecast, the weather remained good, and Sharon, John and Martin M joined Karen at the garden party to celebrate. Click here for photos.

Congratulations also to Rachael who graduated with a 2:1 BSc in Chemistry on the same day. Rachael is now heading to Brighton for a teaching job, and we wish her the best of luck. Also graduating was former group member Louisa who completed her MChem. Congratulations!



Sharon has been awarded the 2011 RSC Marlow Award (one of the awards in the Physical Chemistry section) for “pioneering work in solid-state NMR, combining experiments and first-principles calculations”. She will now give a series of lectures around the UK.


Sharon and Daniel attended the 2011 ScotCHEM Computational Chemistry Symposium in Edinburgh on 7th June.


Sharon, John, Martin M, Valerie and Daniel made the trip over to Glasgow on 9th June to hear a talk by Professor Steven Brown (Warwick). Steven was a PhD student in the Wimperis group with Sharon, and was also John’s PhD supervisor. Afterwards Sharon joined Steve and Steven for dinner.



May 2011


Sharon and John attended the SMARTER 2 Workshop in Aveiro, Portugal from 23-27th May, focussed on structural elucidation by combining magnetic resonance, computation, modelling and diffraction. Sharon gave a talk entitled “Disorder and Dynamics in Hydroxy Silicates studied by Solid-State NMR and First-Principles Calculations”, while John presented a poster on his work on “Structure and Disorder in Hydrous Wadsleyite probed by Solid-State NMR and First-Principles Calculations”.

Phys. Chem. C. Daniel’s work with Professor Paul Wright has also been accepted in Microporous and Mesoporous Materials.



As part of the third year undergraduate “mini project”, Daniel, John and Sharon worked with students Martin Peeks, Harriet Hopper, Emily Murphy, Sarah Morgan, Mark Nettleship and Gabrielle Stann on a project aimed at improving the synthesis of the gallium phosphate microporous material Cloverite. Materials were characterised using solid-state 31P, 13C and 71Ga NMR alongside diffraction. Congratulations to the group for their hard work, and an excellent presentation and group report. 


April 2011


The group attended the annual symposium of the UK 850 MHz Solid-State NMR facility in Warwick on April 4th. John gave the first talk of the day entitled “High-Resolution Solid-State NMR of Inner-Earth Minerals”. The day consisted of 13 talks by users of the facility from 10 different institutions. The next day Sharon took part in the meeting of the International Advisory Board with the National  Management Committee of the facility.


Emily and Rachael handed in their undergraduate reports this month and completed the projects with a viva examination. Emily’s thesis was entitled “NMR Investigation of Phosphate-Based Microporous Materials”, while Rachael’s report described the “NMR Investigation of Pyrochlore Ceramics for the Encapsulation of Radioactive Waste”.
