Chemistry (MSc by Research)

Biomedical materials engineering develops biomaterials that are manufactured to be suitable for use as medical devices. Nanomaterials of oxides, metals, carbon-based materials (i.e. graphene, nanotubes, etc.), and polymers make up the vast majority of biomaterials. For practical uses (sensors, biosensors, nanozymes etc.) nanomaterials are usually chemically modified at the surface forming composite materials. Unlike, the bulk properties of these materials which are generally well known, the properties arising at the nanoscale from surfaces and interfaces in contact to the biological environment are peculiar to the system. The chemistry of surfaces and interfaces and their characterization are therefore key to a quantitative understanding of the materials properties. Controlling such properties is imperative to allow for the prediction of the materials behaviour when immerse in the biological environment. This will not only affect biomedical processes at the materials interfaces but also any industrial and technological applications that see such systems at the heart of their approaches. The PhD student will undertake novel research using multiscale computational approaches capable of gaining nanoscale and microscale insights into the chemistry, structure and processes at the surfaces and interfaces of biomedically relevant materials. The details of the project will be discussed with the candidate and the project will be tailored based on the candidate’s research interest.

Key factors in modelling catalytic materials are related to their surface properties. Surface morphology is known to affect catalytic activity. Here one of the key challenges is to identify strategies to enhance the expression of such surfaces and also to prevent their disappearance over time. To understand how surface composition affects surface catalysis, we will be using molecular modelling to predict surface composition at relevant conditions of temperature and pressure. By mapping the energetics of the interactions, we can calculate temperature of desorption and predict nanoparticle morphology of catalytically relevant oxides. The PhD student will undertake novel research using multiscale computational approaches capable of gaining nanoscale insights into the chemistry, structure and processes at the surfaces of materials for catalysis. We will be using molecular modelling based on classical and ab initio techniques. The details of the project will be discussed with the candidate and the project will be tailored based on the candidate’s research interest.

Key factors in modelling energy materials are related to their properties. The modelling of transport properties in polycrystalline materials is key to understand performance of solid-state electrolytes. The interfaces and grain boundaries control such properties. Most interfaces are not pristine and dopants are likely to segregate, thus impacting materials’ properties. Grain boundaries are structural features that can enhance conductivity or blocks transport across the interface, depending on the nature of the material considered. Here, the segregation behaviour is highly dependent on the grain boundary structure, and there is scope to control the transport properties by changing the structure these interfaces. Grain boundary engineering will be at the core of this project. The PhD student will undertake novel research using multiscale computational approaches capable of gaining nanoscale insights into the chemistry, structure and processes at the interfaces of materials for energy generation. We will be using molecular modelling based on classical and ab initio techniques. The details of the project will be discussed with the candidate and the project will be tailored based on the candidate’s research interest.

Key factors in modelling nuclear materials are related to their properties. The student can choose topics related to nuclear materials for energy generation, or their storage and disposal. In polycrystalline nuclear materials, most interfaces are not pristine, and dopants and fission products are likely to segregate, impacting the mass and thermal transport properties at the grain boundaries. This ultimately affects the way we engineer compositions that can better sustain the extreme conditions of the surrounding environments. As nuclear materials are exposed to extreme environments, corrosion may occur at their surfaces. The effect of the environment on the surfaces is key to understand corrosion for the long-term storage and disposal of nuclear materials. The PhD student will undertake novel research using multiscale computational approaches capable of gaining nanoscale insights into the chemistry, structure and processes at the surfaces and interfaces of materials for nuclear applications. We will be using molecular modelling based on classical and ab initio techniques.

Chitosan is a polysaccharide which is usually extracted from the shells of crabs, it is unique in nature as it is positively charged. When chitosan is mixed with tripolyphosphate nanoparticles can form. Their size, charge and stability will depend on the chitosan to tripolyphosphate ratio. In this project, nanoparticle size and stability (change in size) will be examined using, for example, viscometry and turbidimetry.

• Professor Gordon Morris

This research will be in the area of synthetic organic chemistry and will focus specifically on the synthesis of heterocyclic natural products. The targets of this project are the indolizidine and pyrrolizidine alkaloids. These systems are of interest in the possible treatment of various diseases such as cancer, diabetes and viral infections such as AIDS, and some of them have the potential to function as potent analgesics or as potential treatments for Alzheimer’s disease and other neurological disorders. Examples of such compounds include the well-known "poison frog alkaloids".
