Materials Research Exchange 2018

In Knowledge Transfer, Seminars and Keynotes on 2018/05/08 at 10:14 am

We spoke at the UK Advanced Material Research & Investor Showcase event in London on 13th March. The event, organised by EPSRC, Innovate UK and KTN, and supported by DSTL, was aimed at materials scientists and engineers who work at the research:industry:academia interface in the UK. It was a fabulous opportunity to learn more about the facilities the UK plcs and Universities have for materials processing and characterization, and also to find out more about the ongoing projects co-sponsored by Innovate UK.

We were invited to present our ongoing project in collaboration with FAR UK Ltd, ‘L3:An Integrated approach towards zero net emissions via lightweight manufacturing’, which is researching how to achieve weight reduction in composites (i.e. fibre-reinforced polymers) without sacrificing mechanical performance, and using a cost effective manufacturing process.

The process under development is one that has the ability to use lower cost composite materials and is inherently near-zero waste, both in its production strategy and also because it does not use environmentally damaging materials.

The process makes porous polymeric structures where the inherent loss of mechanical properties is mitigated by the addition of fibres (initially glass and carbon, expected to be replaced by naturally derived fibres in the near future).  Additionally, the microstructure of the pores and the orientation of the fibres can be controlled in-situ using external means such as sonication and magnetic fields.

This project is allowing us to move forward towards the realisation of topology optimisation and its true implementation for composite manufacturing processes.

A manufacturing protocol for the production of biocompatible porous catalysts

In Publications, Seminars and Keynotes on 2018/02/09 at 2:23 pm

Mohammad Alqahtani, researcher of the Multifunctional Materials Lab, is conducting research to develop a new manufacturing method and testing protocol for the fabrication of biocompatible catalyst-carrier for controlled drug delivery. The carrier could be used as a prodrug activation agent when implanted in cancerous tissues in the human body. When orally-ingested drugs are deployed into the area under treatment through the blood stream, the catalyst could activate the prodrugs and these affect the area by releasing anticancer treatment. In this research, a titanium-based carrier was used to manufacture the medical device due to their biocompatibility and non cytotoxicity.

In a feasibility study, the samples were made as porous carriers.  Porous materials have larger surface area than solid materials. Therefore, when the contact area between the drug and the carrier increases this has a potency effect on the effectiveness of the drug.

Functionally-Tailored Cellular Structures

In Publications, Seminars and Keynotes on 2018/01/10 at 1:41 pm

Many applications in science and engineering can benefit from the control of porosity
gradients. Producing heterogeneous materials allows the properties of that material to
be tailored more specifically to the requirements, reducing resource consumption and
weight. A designed microstructure is able to produce similar strength and stiffness values to a homogenous material at a reduced weight by removing discontinuities between phases where stress concentrations occur.

Joe Holt, researcher of the Multifunctional materials Lab, studying at the EPSRC Centre for Doctoral Training in Embedded Intelligence and co-sponsored by FAR UK Ltd, has presented our work on functionally tailored cellular structures via topology optimisation.

20170701_joe_poster.png

A tailored cellular structure is realised by topology optimisation of a volume loaded
in compression. The optimisation is set-up to incorporate a full spectrum of densities
of the parent material, as to simulate a cellular solid of varying density. The resulting
structure is produced by ultrasound sonication of a polyurethane foam system during
the foam rise. Targeted sonication power and frequency allows the manipulation of
density in specific regions, producing a finished structure with a density profile representing the results of the topology optimisation.

3D Acoustic-Structure Interaction of Ultrasound in Fluids for the Manufacture of Graded Materials

In Publications, Seminars and Keynotes on 2017/10/20 at 2:55 pm

Functionally graded materials engineered to meet specific requirements are being increasingly sought after for advanced engineering projects, yet the possibilities for their manufacture lag behind their design. The ability to control the porosity of a cellular material is one such method for adding functional gradients within materials. A novel
technique using ultrasound to control the porosity in reacting polymers shows potential to effectively mass-manufacture porosity tailored polymeric foams. In this work the pressure field in a metastable polymer produced by multiple ultrasonic sources is
modeled at distinct stages of the polymerisation reaction.

‘Robots at the Movies’: The portrayal of robots and androids in contemporary films

In Seminars and Keynotes on 2017/05/17 at 4:57 pm

Automata, robots and androids have been a creation and fascination for humans over centuries.  From Maria (Metropolis, 1927), R2D2 and C3PO (Star Wars, 1977), WALL-E (2008), The Terminators (1984, 1991, 2003) to Transformers (2007), they have been portrayed as our friends, adversaries, alien to almost human, invaders and enslavers or as our saviours and trusted companions. These portrayals in the movies have reflected and perhaps influenced our opinion of them. Join us for an amusing evening reviewing our relationship with these technologies as reflected in their portrayal in the movie industry.

Manufacturing Functionality: from SFF to truly SFF

In Seminars and Keynotes on 2016/04/05 at 8:13 pm

Solid Free Form (SFF) fabrication, also known as Rapid prototyping (RP) or Layered Manufacturing (LM), creates arbitrary 3D shapes directly from Computer-Aided Design (CAD) data. It has been around for two decades now. From its early age it demonstrated tremendous advantages for the Computer-Aided Manufacturing (CAM) industry compared to traditional manufacturing methods such as CNC machining or casting. The venues for exploration appeared endless until users started to hit a ceiling; the name ‘rapid’ became almost ironic because the layering process is a very slow one, the palette of materials to handle is limited and the advertised label ‘net-shape’ is ‘near-shape’ – on a lucky day-. We are now over the hype of SFF, RP and LM but still have needs to create heterogeneous structures that have intrinsic multifunctionality. The Multifunctional Materials Manufacturing Lab in Loughborough University works on new manufacturing methods that allows a truly free form fabrication and the engineering of composition and structure for the creation of materials that are smart, responsive to their environment and possess synergistic properties that enhance their behaviour. These types of high performance materials offer great promise in fields such as bioengineering and transport (i.e. automotive and aerospace).

Mathematical Modelling of the use of Ultrasound to Tailor Polymers

In Info, Seminars and Keynotes on 2015/01/27 at 12:13 pm

Materials whose internal porosity can be tailored during the manufacturing process could be of use in a wide range of applications such as bone scaffolds (to help new bone grow from stem cells).  A recent method for achieving such a manufacturing process involves the acoustic irradiation of a reacting polymer foam which then results in a final sample with a graded porosity.  This talk will present the first mathematical model of this process. The polymerisation process is complex involving, for example, bubble dynamics, evolving rheology, two phases, reaction kinetics, and gas diffusion.  In addition, the model has to include the effects of the irradiating ultrasound.  The model I will present treats the evolving fluid as a multimode Oldroyd B system and will focus on a single moving bubble boundary using a Lagrangian frame of reference.  After looking at the role that inertia has on the dynamics of the system, a multi-bubble model is constructed that generates a heterogeneous bubble size distribution shaped by the ultrasonic standing wave pattern.

My colleague Dr Tony Mulholland, from the Department of Mathematics and Statistics, University of Strathclyde, will present this remarkable piece of work on the 27th January 2015 at 1pm in venue: S.1.73 (Materials Department, Loughborough University). Join us if you can.
