Research Project: Joule-heatable hybrid nancarbon network supports for CO2 captrue
Supervisors: Chris Howard (UCL), Milo Shaffer (Imperial)
Tommaso graduated from the University of Padova with a Master’s degree in Materials Science; his Master’s thesis was focused on the functionalisation of carbon nanostructures for non-conventional composite materials.
Carbon nanostructures are known for their high electrical conductivity, mechanical strength and surface area, and Tommaso aims to develop a hybrid carbon nanotube/graphene aerogel with enhanced surface area and accessible hierarchical porosity. This nanocarbon network will be used as support for Layered Double Hydroxides (LDHs) to enhance the CO2 adsorption capacity of LDH platelets. The high surface area and porosity of the support can maximise the gas accessibility and minimise the coarsening of the LDHs, improving multi-cycle stability. Furthermore, the aerogel itself will be used to heat up the LDHs during the CO2 adsorption/desorption temperature swings, via direct Joule heating, allowing uniquely fast cycling relevant to applications.
A wide range of complementary characterisation techniques will be employed in the study of the hybrid nanocarbon-sorbent material. Being a member of the CDT-ACM will support Tommaso’s project in the development of new 3D methods to characterise the anisotropic hierarchical porosity of the hybrid network.
Research Project: Combining electron correlations and topology: novel electronic phases in the pyrochlore iridates
Supervisors: Des McMorrow (UCL), David Payne (Imperial)
Cameron joined the CDT-ACM having graduated from the University of Cambridge with a BA and MSci in Natural Sciences (specialising in physics). Cameron’s interest in correlated electron systems began during a research placement at Caltech, where he studied the ferromagnetic phase transition of lithium osmate using a novel femtosecond-resolved second harmonic rotational anisotropy spectrometer. For his PhD Cameron is working with Des McMorrow and David Payne to study the pyrochlore iridates – a group of materials in which the delicate interplay between electric correlations and spin-orbit coupling lead to exotic quantum phases. These phases will be probed with X-ray scattering and angle-resolved photoemission techniques at facilities in the UK and abroad.
Research Project: Single atom devices with controllable electrical and optical properties
Supervisors: Neil Curson (UCL), Steven Schofield (UCL)
Eleanor is using cryogenic scanning tunneling microscopy to isolate electrons for making qubits (quantum bits) for a quantum computer. This is why the ACM CDT should give Eleanor a head start, because she will learn about many other important techniques used in research labs worldwide. Having first completed an Electrical Engineering Master’s in Paris, Eleanor came to UCL to do a MSc in Nanotechnology last year. She was then motivated to look for the right PhD in experimental quantum physics to continue her research. A phosphorous atom has one more electron than a silicon one, so if a phosphorous atom is put inside a silicon lattice, there is an extra electron in the structure. This extra electron can have either an up or a down spin and can therefore be used to make a qubit (quantum bit). Eleanor’s PhD looks at ways of putting this single atom inside the silicon and keeping track of where it is.

Research Project: Advanced characterisation of small molecule adsorption in complex solid materials
Supervisors: Ivan Parkin (UCL), Daryl Williams (Imperial)
Elwin graduated with an MEng in Chemical Engineering from UCL. Elwin’s PhD research is primarily concerned with understanding the methods of sorption for a range of organic molecules onto semi-amorphous substrates including hair, cotton and fibrous proteins. This project utilises both gravimetric and chromatographic experimental techniques, as well as developing relevant models and descriptors to characterise the behaviour of both substrate and solute. The project is being completed alongside industrial experience with P&G for applications in their line of personal care products.
Research Project: High-dielectric contstant organic for high efficiency photovoltaics
Supervisors: Fracno Cacialli (UCL), Natalie Stingelin (Imperial), Hugo Bronstein (Cambridge)
Prior to his PhD studies Ioannis completed a BSc in Physics and an MRes in Nanomaterials at Imperial College London. Ioannis is very interested in renewable energy and more specifically third generation solar cells. During his MRes Ioannis researched solution processed photovoltaics based upon inorganic nanocrystals. The focus of his PhD project is turned towards organic semiconductor photovoltaics where Ioannis aims to develop and characterise acceptors and donors with increased dielectric constants in order to achieve high efficiency solution processed solar cells.
Research Project: Nanoscale engineering of multifunctional probes for cancer diagnosis and theraputics
Supervisors: Thanh Nguyen (UCL), Fang Xie (Imperial)
Caomihe received her B.Sc. in Chemistry with Biophysical Chemistry from University College Dublin in 2016. She then moved to London to pursue an MRes degree in Nanomaterials at Imperial College London. Caoimhe is now undertaking a PhD project with the CDT-ACM under the supervision of Dr. Fang Xie and Professor Thanh Nguyen which aims to address the current difficulty with early stage cancer detection through the use of functionalized nano-agents, and provide simultaneous treatment.
Research Project: Deformation mechanisms in Co/Ni-base superalloys
Supervisor: David Dye (Imperial)
Thomas graduated in 2017 from the University of Cambridge, with an MSci project in the physical metallurgy of high-entropy alloys. His PhD investigates deformation mechanisms in novel Co/Ni-base dual phase polycrystalline superalloys for use in jet engines, in collaboration with Rolls-Royce. This involves observing dislocations and stacking faults during creep via TEM, and measuring their energies. Grain boundary sliding and microstructural changes will be characterised using EBSD, SEM and DIC. Understanding the effect of stress, temperature and composition on these behaviours will be used to develop and optimise mechanical properties.

Research Project: Designing nanostructural advanced polymer materials for gas sensing and adsorption
Supervisors: Joao Cabral, Alex Porter, Julia Higgins (Imperial)
Roisin graduated from the University of Leeds where she gained her masters in chemical engineering. During her time at Leeds Roisin’s research was primarily based on the study of crystallisation of organic materials, specifically active pharmaceutical ingredients. Roisin’s current research is focused on gaining an understanding of the thermodynamics, phase behaviour and route of formation of porous polymer gas adsorbers. If a full understanding of these properties can be obtained, the structure and size of the pores could be fine-tuned to broaden the applications of the material.
Research Project: Structural and ambient pressure XPS investigation of metal/metal-oxide interface
Supervisors: David Payne (Imperial), Tien-Lin Lee (Diamond Light Source Ltd)
Paul completed an MSci in Chemistry from the University of Bristol graduating in 2016. For his PhD studies, Paul is based at both Imperial College London in David Payne’s advanced photoelectron spectroscopy group and at Diamond Light Source Ltd as part of the research group on beamline I09. Paul’s project entails the investigation of metal/ metal-oxide interfaces with a particular focus on metals deposited on magnetite (Fe3O4). Remarkably, the Fe3O4(100) surface is able to stabilise a range of single metal centres, or adatoms, up to temperatures of 700 K. These adatoms have promising potential as single atom catalysts with much improved properties over more conventional heterogeneous catalysts.
Research Project: Layered double hydroxide nanomaterials
Supervisors: Neal Skipper (UCL), Milo Shaffer (Imperial)
Aasim graduated with a masters in Chemistry (MChem), from Loughborough University. Aasim then worked as a researcher, where he looked at 3D-printing systems, which created objects via the curing of photopolymer resins. In particular, he looked at hybridising these resins with inorganic nanoparticles, to enhance their properties. Aasim is now undertaking his PhD, which is based in the Physics Department at UCL and the Chemistry Department at Imperial College. His project looks at a class of materials, known as Layered Double Hydroxides (LDH); he will aim to understand these materials on a more fundamental level. Furthermore, Aasim will optimise the chemistry of LDHs, in order to render them more effective in their various applications.
