• #### A general catalytic β-C–H carbonylation of aliphatic amines to β-lactams ﻿

(2018-06-02)
Carbonyl compounds are of central importance to organic chemistry and their reactions have been described as the ‘backbone of organic synthesis’. Over recent decades, palladium-catalysed C–H carbonylation reactions have ...
• #### A Simulation Approach to the Study of Bacterial Secretion Proteins ﻿

(2017-07-22)
Knowledge of the structure and dynamics of cellular protein complexes is essential for understanding their functionally relevant interactions. In Gram-negative bacteria, the complex machinery associated with the type II ...
• #### Accelerated sampling of energy landscapes ﻿

(2017-09-28)
In this project, various computational energy landscape methods were accelerated using graphics processing units (GPUs). Basin-hopping global optimisation was treated using a version of the limited-memory BFGS algorithm ...

(1986-10-21)
• #### Adsorption of alkyl amides: monolayer structures and mixing behaviour ﻿

(2011-02-08)
In this work monolayers of alkyl amides adsorbed on a graphite surface have been successfully identified and investigated using a combination of synchrotron X-ray and neutron diffraction and Differential Scanning Calorimetry ...
• #### Aggregation of alpha-synuclein using single-molecule spectroscopy ﻿

(Department of Chemistry, University of Cambridge, 2017-03-23)
The aggregation of alpha-synuclein (αS) protein from soluble monomer into solid amyloid fibrils in the brain is associated with a range of devastating neurodegenerative disorders such as Parkinson’s disease. Soluble oligomers ...
• #### An interdisciplinary approach to studying mechanistic, structural and toxic features of protein aggregates associated with neurodegenerative disorders. ﻿

(2018-07-20)
The misfolding and aggregation of proteins is closely associated with more than fifty human disorders, including Alzheimer's and Parkinson's diseases, all of which are currently incurable and many represent a major threat ...
• #### Applying single-molecule localisation microscopy to achieve virtual optical sectioning and study T-cell activation ﻿

(2015-10-06)
Single-molecule localisation microscopy (SMLM) allows imaging of fluorescently-tagged proteins in live cells with a precision well below that of the diffraction limit. As a single-molecule technique, it has also introduced ...
• #### An approach to catalytic asymmetric electrocyclization ﻿

(2010-02-09)
Chapter 1 outlines the development of a catalytic electrocyclic process and its exploitation in asymmetric synthesis. Since Woodward and Hoffmann delineated a rationale for the mechanism and stereochemistry of these reactions ...
• #### Aqueous Self-Assembly with Cucurbit[n]urils: From Solution to Emulsion ﻿

(2018-04-07)
Making use of the non-covalent bond to make materials is of great interest in many fields of research. This PhD thesis describes a variety of highly interdisciplinary research undertaken at the interface between chemistry, ...
