Biography

Responsibilities

 

I am Director of Education in the Department of Physics and have overall responsibility for educational policy and delivery of teaching within the Department. This role includes Chairing the Department's Education Committee and membership of: Physics Board of Studies, Senior Management Committee, Departmental Progression Committee, Board of Examiners, Student Voice Committee, Research Staff Consultative Committee and Faculty Education Committee.

I have a passion for curriculum development, adapting the learning environment in response to technological developments (such as generative Artificial Intelligence) and ensuring the delivery of an excellent learning experience in consultation with both students and colleagues.

 

Research

I am a member of the Condensed Matter Physics section (https://www.dur.ac.uk/research/institutes-and-centres/condensed-matter-physics/) and lead a small research group focused on nanostructured materials, with particular emphasis on sustainability, energy conversion and energy storage. 

Energy Conversion and Storage

Low-cost, environmentally sustainable, and safe electrochemical energy storage and conversion is crucial for the green energy transition. Our work addresses two areas: 

(1) Supercapacitors

Current battery technologies face limitations including short cycle life, environmental impact, safety concerns, and recycling difficulties. Supercapacitors address many of these issues but suffer from low energy density, which must be improved for broader adoption. By the use of low concentrations of two-dimensional materials such as few layer graphene, produced through environmentally sustainable shear exfoliation into aqueous suspensions, as a conductive additive in activated carbon electrodes we have demonstrated that significant improvements in rate capability and energy storage are possible in electric double layer capacitors.

The matching of electrode material and electrolyte is a key aspect of optimising performance, including longevity in supercapacitors. By considering the behaviour of nanostructured binder-free supercapacitor electrodes consisting of layered MoS2 supported on carbon cloth in six aqueous electrolytes and correlating the results with morphology and composition we were able to identify the electrolyte which offered the best combination of performance and cycle life. The value of this approach was demonstrated by the production of an asymmetric supercapacitor consisting of binder free carbon cloth supported MoS2 and MnO2 electrodes in 1.0M Na2SO4 with a working voltage window of 2.0 V and a capacity retention of 80% after 15,000 charge-discharge cycles.

(2) Energy Conversion

The high gravimetric energy density of H2, the high Earth-abundance of potential sources and the fact that water, rather than environmentally-damaging gases, are the byproduct of its combustion make it highly attractive as a carbon-neutral energy source, if produced by 'green' routes. Electrolysis of water employing renewable energy sources is such a route but suffers from the high cost of electrocatalysts typically employed in this process. Non-noble metal bases electrocatalysts such as supported nanostructures MoS2 offer practical and scalable alternatives. In recent work we have demonstrated that a careful balance between the electrolyte accessible surface area, resulting from its hierarchical nanostructured morphology, concentration of active sites, proportion of the conductive electroactive metastable 1T phase of MoS2 compared with the stable 2H phase and crystallinity is required to achieve the best catalytic behaviour.

Non-Equilibrium Self-Organised Nanoscale Surface Structures

The competition between roughening induced by the ion induced irradiation of solid surfaces and relaxation processes such as diffusion which smooth the surface can lead to the formation of quasi-periodic structures such as dots, holes and ripples. This process provides a maskless route for the production of functional surfaces and templates which can be used in applications as diverse as solar cells and bio-compatible surfaces. In our research we combine experimental measurement with numerical simulation to understand these processes with the ultimate goal of deriving predictive rules for the production of surface patterns tailored to specific uses.

Liquid-liquid interface deposition of two-dimensional materials

Thin films and van der Waals heterostructures (vdWHs) derived from two-dimensional solids offer enormous potential for a broad range of novel, energy efficient devices, however their use is currently hampered by slow, labour-intensive fabrication methods often employing hazardous chemicals. We have demonstrated a novel liquid-liquid interface technique for rapid, low-cost, and environmentally-friendly production of ultra-thin films and vdWHs of two-dimensional solids from aqueous surfactant-stabilized suspensions. The approach is generic to two-dimensional materials which can be stabilized in aqueous suspension by a surfactant and the resulting films can be transferred to an arbitrary substrate by a range of approaches. We have demonstrated the wide applicability of this technique  through production of thin films on a variety of substrates, deposition of transparent, highly conductive graphene films by the fabrication of a vdWHs of MoS2, WS2 and few-layer graphene.
