91福利

Józef Lewandowski was awarded "for his outstanding accomplishments to date and his promise in the development of solid-state NMR methodology and its application to the study of biomolecular structure and dynamics." The prize will be presented during ISMAR Conference in Shanghai.

Anish Mistry (supervisor: David Fox) is a finalist in the Three Minute Thesis competition being held this afternoon as part of the Postgraduate Research Showcase:

91福利 Chemistry took part in the 2015 Cheltenham Festival of Science with hands-on demonstrations by and helpers, and a lecture by .

ACS Nano has highlighted new work from 91福利 on graphene electrochemistry in its "In Nano" section ('), featuring the most important work in the journal. Led by Dr. Aleix Guell and Prof. Patrick Unwin, the team employed the unique Scanning Electrochemical Cell Microscopy (SECCM) technique - invented at 91福利 - to highlight how the number of graphene layers and graphene edges influenced electrochemical activity; and, further, how any differences in activity depended on the redox mediator and the electronic band structure of the different characteristic graphene and graphite structural motifs. With this work, the 91福利 Electrochemistry and Interfaces Group has brought definitive new insights that help to reveal the complex and exciting world of graphene electrochemistry, contributing major understanding on the electrochemical activity of sp2 carbons, which are finding increasing use for energy and sensing applications.

At the Chemistry Departments annual postgraduate symposium, Robert Deller () and Athina anastasaki () won the prizes for the best PhD Theses. The Thesis prize is Sponsored by the Faculty of Science.

The journal editors have selected a recent paper in Chemistry–A European Journal from Philip Chan’s group as a Hot Paper. The work describes a synthetic method to prepare 3a,6-methanoisoindole esters by gold(I)-catalyzed tandem 1,2-acyloxy migration/Nazarov cyclization and Diels-Alder reaction of 1,4,9-dienyne esters. One example was found to inhibit binding of tumor necrosis factor-a (TNF-a) to the tumor necrosis factor receptor 1 (TNFR1) site and TNF-induced nuclear factor k-light-chain-enhancer of activated B cells (NF-kB) activation in cell at a half-maximal inhibitory concentration (IC₅₀) value of 6.6 mM. The study showed the isoindolyl derivative to exhibit low toxicity toward human hepatocellular liver carcinoma (HepG2) cells and its possible mode of activity based on molecular modeling analysis.

Philip Chan’s group have this week published a paper in Journal of the American Chemical Society describing a synthetic method to prepare tricyclic bridged heptenones and hexenones from gold(I)-catalyzed double cycloisomerization of 1,11-dien-3,9-diyne benzoates. The work found a divergence in product selectivity could be achieved by fine-tuning the steric nature of the ligand of the Au(I) catalyst. In the presence of the catalyst [MeCNAu(JohnPhos)]⁺SbF₆^-, a tandem 1,3-acyloxy migration/metallo-Nazarov cyclization/1,6-enyne addition/Cope rearrangement of the substrate selectively occurred to afford the seven-membered ring system. In contrast, with the [MeCNAu(Me₄tBuXPhos)]⁺SbF₆^- catalyst, the 1,11-dien-3,9-diyne benzoate was observed to undergo a more rapid tandem 1,3-acyloxy migration/metallo-Nazarov cyclization/[4 + 2]-cyclization pathway to give the bridged hexenone.

The and groups are involved in 2 new projects intended to promote translation of new technologies. These projects are funded by the Industrial Biocatalyst program supported by Innovate UK, BBSRC and EPSRC and span a range of UK universities and companies.

Adrian Chaplin has been award one of this years Harrison-Meldola Memorial Prizes from the Royal Society of Chemistry.

Józef Lewandowski in collaboration with Lyndon Emsley (EPFL, Lausanne/ENS-Lyon) and Martin Blackledge (IBS, Grenoble) reports in on a direct observation of hierarchy of protein and solvent motions in protein conformational energy landscape. The findings of the study employing a series of variable temperature magic angle spinning multinuclear NMR relaxation measurements on a nanocrystalline protein reconcile divergent interpretations from techniques that are individually sensitive to dynamic phenomena occurring on different time scales and at different locations in protein-solvent systems.

'It appears that a series of catalysts developed in the 91福利 Chemistry department have the ability to achieve the impossible: 'Impossible Ketone and Imine Reductions Made Possible by the Ruthenium Tethered Catalyst' reads the headline of the Johnson Matthey (JM) advert on the back of the April 2015 issue of Chemistry World. The tethered ruthenium catalysts described in the advert were first developed and reported by Professor Martin Wills and his group, and have since been developed extensively at 91福利 and adopted by companies worldwide, including JM.
