Mathematical modelling of sonicated bubbles

In Publications on 2017/05/31 at 5:10 pm

One possible manufacturing method for bone scaffolds used in regenerative medicine involves the acoustic irradiation of a reacting polymer foam to generate a graded porosity. Sonication of foams have been our focus of research for many years now as this technology allows the porosity tailoring of cellular materials.

We have joined forces with Prof Mulholland’s team (Dr Barlow and Dr Bradley) at Strathclyde University and worked on a mathematical model of a non-reacting process in order to develop theoretical confirmation of the influence of the acoustic signal on the polymer foam.

The model describes single bubble growth in a free rising, nonreacting polymer foam irradiated by an acoustic standing wave and incorporates the effects of inertia. Investigations are carried out to explore the influence of inertia on the bubble volume, fluid pressure and the stress tensors of the foam, and to explore the effect of fluid viscosity and acoustic pressure amplitude on the final bubble volume, and the curing time. A key result is that increasing the applied acoustic pressure is shown to result in a reduced steady state bubble volume, indicating that ultrasonic irradiation has the potential to produce tailored porosity profiles in cellular materials such as bioengineering scaffolds and light-weight structures.

Our work has been compiled as a paper recently published in the Journal of Non-Newtonian Fluid Mechanics and can be found here (Open Access).

‘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.

An integrated approach towards zero net emissions via lightweight manufacturing

In Funding on 2017/03/14 at 4:05 pm

We have managed to secure funding from the Office for Low Emission Vehicles, the Department for Business, Energy and Industrial Strategy (BEIS), Innovate UK and Far UK Ltd to develop research that makes an impact on emissions savings from road vehicles.

My Multifunctional Materials Manufacturing Lab at Wolfson School and my industrial collaborator (Far UK ltd) have been awarded more than £250k to develop excellent science that allows the design and manufacture of low weight structures for vehicle chassis components. Low weight is beneficial for reduced tailpipe emissions for both existing internal combustion engine vehicles but also as an enabler for further electrification of the fleet. The manufacture of the optimised structures via the sonication process incurs another challenge: to achieve mass market weight reduction this needs to be done cost effectively.

This project is part of the Integrated Delivery Programme 13: Low Emission Vehicle Systems (IDP13): Stream 1 – Collaborative technical feasibility studies.

Applying International Standards to manage comfort

Have you ever seen the seat testing device at IKEA? We have used a very similar one in our study.

Open cell polymeric foams can be tailored so that the support provided and the level of stability is customised to people’s needs. For those who are bed bound or wheelchair users the selection of a cushion can improve their health and general well being. Avoiding pressure points, managing sores and permitting air permeability are the three main design specifications that patients and clinicians aim to when choosing a cushion. In addition to that, a functional cushion, such as those who support lateral movements (e.g. leaning sideways to grab a glass of water and be helped to return to your initial position without compromising one’s stability) and protect from vibration and impacts (e.g. dropping off a curb), are the focus of our last research project.

My team and I have had the privilege to work with the biomechanics and physiotherapists at the SMART Centre at Astley Ainslie Hospital in Edinburgh to study how we can help their clinician colleagues understand cushion performance and therefore aid them with the prescription of these to patients and users.

The results from our study have been presented at the PMG 2012 Conference and recently published by the Assistive Technology journal (free e-prints can be collected here). This has allowed us to interact with the community that is preparing the new version of the ISO16840-2:2007 which will regulate developments in this area.

 

Empowering resilient communities

In Publications on 2017/02/06 at 10:58 pm

We have created low-cost housing solutions for the local community in Pabal (India). Those people have a lot of ingenuity but not a lot of money to buy expensive building materials. Only the transport to their villages would cost them a significant amount.

But they have a wealth of natural resources. And amongst them, they have bamboo, a fascinating multifunctional material, ideal for structure-erecting, wind-loading and vibration-proofing due to its heterogeneous porous structure and high shear modulus.

Bamboo: macro and microstructure

We have helped them to build those modular huts by providing them with a set of instructions that are universal and accessible to all, no matter the mother tongue, ability or building skills. In this way they are prepared to adapt and be resilient to the threats posed by natural forces and climate change hazards (e.g. floods, pluvial, wind, earth tremors) and reinforce their coping strategy as a resilient community.

In the process of developing those instructions we have learnt a lot from the Information Design community. There is so much lo learn about user-centric design, cognitive load and the language of actions, perspectives and colours to convey instructions and allow self-guidance. I deeply thank them for having mentored us.
