For further details of these restrictions, please see the introductory section on funded projects earlier in these web pages on 'New DPhil Projects Available'. Additive manufacture of adaptive materials for communications applications Professor Patrick Grant For any antenna system there is a trade-off between antenna bandwidth wide as possiblesize small as possible and efficiency high as possible.

However, using only the current and long-standing, narrow and passive palette of materials suitable for antennas means that this trade-off is unhelpfully constrained, preventing more radical and advantageous designs such as low profile, low detectability, low power and miniaturized platforms.

This project will undertake high risk, novel research in making novel tunable materials for communication applications using our in-house state-of-the-art additive manufacture equipment.

The focus is primarily on materials science and engineering by integrating design, materials and new manufacturing approaches to demonstrate practical ideas for improved antennas.

There will be two integrated areas of materials and manufacture research: Subject to contract this 3-year DPhil in Materials studentship will be funded by Dstl and will provide full fees and maintenance for a student with home or EU fee status.

Information on fee status can be found at http: The research is funded by Dstl. Any questions concerning the project can be addressed to Professor Patrick Grant patrick. General enquiries on how to apply can be made by e mail to graduate.

Further information and an electronic copy of the application form can be found at http: Patrick Grant Super alumina: This will be accomplished by a combination of nanosized 2nd phase additions, grain boundary engineering and customised flaw size distributions produced using ternary additions of sacrificial carbon nanoplatelets or graphene.

The outcome will shift the properties of alumina towards those of SiC whilst retaining its more versatile and cost-effective processability.

The properties of the nanocomposites will be understood through a range of advanced macro- and micro-mechanical property measurements and ballistic impact testing.

Any questions concerning the project can be addressed to Professor Richard Todd richard. The experimental studies will investigate the relationships between applied total strains tensile and compressive, measured by image correlation in 2-D and 3-D and the elastic strains in the graphite crystals measured, for instance, by synchrotron X-ray and neutron diffraction.

The local effects on microstructure and its properties will be examined by correlative Focussed-Ion Beam FIB tomography, electron microscopy, Raman spectroscopy and micromechanical testing at ambient and elevated temperatures.

These studies aim to understand how tensile and compressive deformations are accommodated by competing mechanisms such as micro cracking, basal slip and twinning, and what effects this may have on the coefficient of thermal expansion. These data will provide inputs for non-linear finite element modelling of the behaviour of graphites at elevated temperatures.

The objective is to validate micro-mechanistic models for graphite deformation, and to provide the foundations for future work on irradiated graphites.

During the secondment with the sponsor, the student will engage with NNL's work on modelling and property measurement of irradiated graphites. Candidates with EU fee status are eligible for a fees-only award, but would have to provide funding for their living costs from another source such as personal funds or a scholarship.

Applications will be considered as and when they are received and this position will be filled as soon as possible, but the latest date for receipt of applications will be 25 January Any questions concerning the project can be addressed to Professor James Marrow james.Particle Size and Shape of Catalyst Supports Hydrotreating catalysts come in different sizes and shapes depending on the application and manufacturer.

Common shapes include spheres, pellets, cylinders, trilobe, and quadralobe shaped pieces.

Introduction Particle Surface Area Analysis and Porosity Testing Particle total surface area, porosity and pore size distribution analysis supporting chemical product performance, development and manufacturing Surface area and porosity are important physical properties that impact the quality and utility of solid phase chemicals including agrochemicals, catalysts, additives and pharmaceutical active ingredients. Differences in the surface area and porosity of particles within the material, which otherwise may have the same physical dimensions, can greatly influence its performance characteristics.

This is one of the most important modules for you. The main tools employed in the analysis of processes involve the use of balances to look at material and energy flow in to and out of the process.

Pt catalysts with particle sizes of 2–3 nm and 4–5 nm and PtCo catalysts with sizes of 3–4 nm, 4–5 nm and 7–8 nm were obtained. A potential sweep from V to V was applied to the cathode of membrane electrode assemblies (MEAs) prepared with these catalysts, and the degradation of their mass activity and cell voltage were.
