Interesting in doing a PhD?
Currently we are looking for 3 PhD students at CASC. For any information on this positions, contact Prof Eduardo Saiz (firstname.lastname@example.org):
- Project 1. Development and Characterisation of a Novel, biodegradable Manuka-honey supplemented Collagen biomaterial for application in the treatment of burn and chronic wounds
There is currently a clinical need in cost-effective skin substitute materials able to actively promote wound healing, while preventing infection.Collagen has a strong history in tissue repair, while honey is an effective antimicrobial agent. The objective of this project is to develop homogenous, highly conformable, collagen-honey based materials that have the potential to address this challenge. These material platform could be used in wound healing, providing infection prevention, pH modulation, and mitigating risks associated with antibiotic resistance and use of silver. The work involves the synthesis of the materials as well as their structural, mechanical and biological evaluation.
This project is in collaboration with Welland Medical.
- Project 2. Performance SiC/SiC composites for aerospace application
SiC/SiC composites are typically produced by a multistep process, combining continuous ceramic fibres in a predominantly ceramic matrix. The toughness of the composite is achieved by the application of a fibre interphase coating during the CVI coating and rigidisation step. The fibre coating provides a weak interface that allows for cracks to deviate from the matrix and travel along this interface. By virtue of their chemical composition these CMCs are susceptible to oxidising environments. Over time the composite as a whole, and the interphase coating in particular, can degrade due to cyclic loading and environmental exposures. This can result in reduced mechanical properties and changes in damage or failure mechanisms, in regions that are embrittled or for the composite as a whole.
The project focuses on two main themes:
1. How do localised stresses or strain induce damage in these materials and is this damage self-limiting, or does localised damage lead to subsequent environmental time-dependent degradation of residual properties? This part of the project will aim to
– Characterise damage generated by thermally induced stresses or localised mechanical stress
– Determine if environmental degradation is occurring in that localised region of damage
– Quantify whether damage induced from thermal gradients/localised stresses propagates over time
2. How do differing surface conditions impact on combined effects of environmental exposure and mechanical or thermal cycles?
- how do coated faces degrade?
- how do coating preparation methods such as grit blasting affect damage progression?
- how does the surface area to volume ratio affect the environmental component of damage?
This project is in collaboration with Rolls Royce.
- Project 3. Processing and characterization of 3D interpenetrating polycrystalline superhard materials
Polycrystalline diamond (PCD) and polycrystalline cubic boron nitride (PcBN) are widely used in applications of earth boring, road planing, mining and machining as superhard materials. These materials are typically sintered under high pressure-high temperature (HPHT) conditions over 5.5 GPa and 1400 ºC. Both PCD and PcBN can be made from diamond or cBN with various grain sizes, depending on the applications. The aim of this project is to develop novel products with 3D interpenetrating “composite” structures of PCD or PcBN with different grain sizes. Unlike traditional composites having one continuous phase and one discrete phase, interpenetrating composites are a new type of composite structures where both phases are continuous and 3D interpenetrating into each other. They mimic many natural materials such as bone and bamboo, enabling superior multifunctional characteristics and properties.
This project is in collaboration with Element 6.
We are also looking for a Postdoctoral researcher:
- Research Associate in Fabrication of Graphene Coatings on Advanced High Strength Steel
Applications are invited for a Research Associate in the Department of Materials at Imperial College, London to undertake research on the design, fabrication and testing of graphene coatings on high strength steel in a project funded by Arcelor Mittal.
Your duties and responsibilities will be to assist in the developing and testing of graphene coatings on advanced high strength steel. And you will also have the opportunity to develop teaching experience. For example, organising an undergraduate lab experiment, supervising MEng research projects and helping with the supervision of PhD students on linked projects.
Candidates/post holders will be expected to demonstrate the following:
