Scott, Fox and Gibson develop 'metallohelical antifreezes'

6 days 19 hours ago

A collaboration between the Fox, Scott and Gibson groups has been published in the Journal of the American Chemical Society. The team were inspired by how small helical antifreeze proteins in Nature enable extreomophiles to survive low temperatures, where other species would not survive. Rather than using traditional peptide/protein chemistry, the team used self-assembled metallohelicates which have similar dimensions to a small alpha helix, and found some which were remarkably potent at stopping ice crystal growth ; a major technological challenge in applications from wind farms, to aircraft to cryopreservation. Modelling studies showed that the underlying activity could be linked the patches of hydrophobicity (water liking) and hydrophobicity (water hating).

Congratulations to Pat Unwin who is to be awarded the Charles N. Reilley Award by SEAC.

2 months 1 week ago

Pat Unwin has been selected by the Society of Electroanalytical Chemistry to receive the 2018 Charles N. Reilley Award. The Award recognizes outstanding research contributions in electroanalytical chemistry and will be presented at a special symposium at Pittcon in Orlando in February next year.

Pat will be the 35th winner of the Award and the first person from the UK to receive it. The Award is given in memory of the renowned US analytical chemist Charles N. Reilley and celebrates scientists whose work advances fundamental understanding in electroanalytical science over empiricism.

Pat’s group has made spectacular advances in instrumental electrochemistry in the past few years, developing innovative electrochemical imaging probes to visualise interfacial dynamic processes of wide applicability, from electrocatalysts to living cells.
