Investigation of pyrazine:diacid co-crystal systems at high pressure

Oswald, Iain (Principal Investigator) Ward, Martin (Co-investigator) Bull, Craig L. (Co-investigator) Funnell, Nicholas P. (Co-investigator)

The aim of this proposal is to follow the changes in the hydrogen bonding
interaction in the pyrazine:oxalic acid and the Pyrazine:maleic acid co-crystals to complete our combined synchrotron and neutron study of the pyrazine:diacid
system.

Investigation of maleic-d2 acid isomerization at high pressure

Ward, Martin (Principal Investigator) Oswald, Iain (Co-investigator)

We will use central facilities time (ISIS neutron and muon facility) to study the conversion of maleic to fumaric acid under high pressure and temperature conditions. Experiments performed in-house show that temperature of pressure alone do not significantly influence the conversion of maleic to fumaric acid; however, the combination of both does result in successful conversion. Neutron experiments will elucidate the conversion in-situ, as it progresses, and allow us to identify ciritcal conditions of temperature and pressure to cause this conversion.

laser-induced nucleation at extreme conditions

Ward, Martin (Principal Investigator) Oswald, Iain (Co-investigator) Alexander, Andrew J (Co-investigator)

In this work we will explore the use of a focussed beam of light to cause crystals to form inside our high-pressure sample holder. The use of laser light (pulse and continuous) has been shown to be able to cause nucleation (the first step of crystallization) to occur at ambient conditions, we will continue with this to (i) see if it is applicable to high pressure conditions, and (ii) develop the methodology to assist with nucleation studies at extreme conditions.
