Development of Serial Crystallography Methods for Synchrotrons and X-ray Free-Electron Lasers
… 2016). The advent of X-ray free-electron lasers (XFELs) that produce femtosecond pulses of extremely high quality (brilliance) X-ray beams, allows data to be collected before radiation damage has the time to occur (Schlichting, 2015). This thesis will describe the development of novel ‘chip’ based …

Using myoglobin models of oxidases for mechanistic understanding of the oxygen reduction reaction
… art time resolved structural methods like XFEL and a set of newly designed myoglobin modes, I have set out to understand aspects of the oxygen reduction reaction in metalloenzymes that have remained elusive. There are many pathways for the oxygen reduction reaction to take place in …

Structural characterisation of ligand, redox and catalytic states in haem enzymes using in crystallo spectroscopies and serial crystallography.
… of serial crystallography, applied at XFEL and synchrotron sources. Spectroscopic information of the crystals provided by in crystallo spectroscopies was used to validate the structures obtained by Xray crystallography, identify generated species, and assign them within the enzyme …

Fluid Mechanics for Biomedical Applications: Weakly Viscoelastic Electrospray, Flow Focusing and Collapsible Channel Models
… to use Flow Focusing for some applications (e.g. XFEL), chaotic oscillations on the jet, known as whipping, must be avoided. A stability map for axisymmetric and lateral perturbation modes was obtained and compared to previous experimental data, examining the effect of different nozzle geometries …

Serial and Single Crystal Studies of Ligand Binding to Radiation Sensitive Haem Protein DHP-B
… damage-free X-ray Free-Electron Laser (XFEL) structures, ruling out the possibility of the hemichrome species being from the use of cryoprotectant. More research needs to be done to determine whether the hemichrome species has any biological relevance. Comparisons of serial and single …

Ultrafast electron transfer and intersystem crossing in bimetallic molecules
Increasingly, the role of electron spin is an important topic in electron transfer (ET). Coupling between the electronic, spin, and nuclear degrees of freedom play an important role in driving ET and intersystem crossing (ISC) on the ultrafast timescale. In this thesis, ultrafast optical and X-ray …
