[Oliver Henrich]

Dear all,

Monica Olivera from MAE has asked me to advertise this seminar below. The speaker is editor of Physics of Fluids, so it could be of interest to ECRs and PGR students who like to know more about publishing.

Could you please circulate this accordingly and follow the link to register if you like to attend.

Best wishes,
Oliver

We are pleased to announce the next MAE – Mechanical and Aerospace Engineering seminar on Friday the 2nd of June at the Royal College building at the University of Strathclyde in Room: RC345 at 10:30 - 12:30.

Please register here if you wish to attend (any changes will be communicated by email):

Our speaker is Professor Alan Jeffrey Giacomin. Professor Giacomin is a retired Professor of Chemical Engineering, Mechanical and Materials Engineering and Physics, Engineering Physics and Astronomy from Queen’s University in Kingston, Canada. He holds the title of Tier 1 Canada Research Chair in Rheology. He is an Adjunct Professor of Mechanical Engineering at Peking University in Beijing and University of Nevada, Reno. He is a former president of the Canadian Society of Rheology and of The Society of Rheology, and was inducted Fellow of The Society of Rheology.  Professor A.J. Giacomin also serves as sole Editor-in-Chief of Physics of Fluids.

The seminar will include a talk by Prof Giacomin, a coffee break and a Physics of fluids focused seminar. Professor Giacomin has led Physics of Fluids as its Editor-in-Chief since 2016. This lecture is designed to interest authors, new and old. It tells the story of the journal’s surging success, with special focus on Scotland contributions. It will be of particular interest to Early Career Scholars to deepen their understanding of editing and journal publishing.

The topic of his technical talk will be: Recent Advances in Polymer Viscoelasticity from General Rigid Bead-Rod Theory.

Abstract: One good way to explain the elasticity of a polymeric liquid, is to just consider the orientation distribution of the macromolecules. When exploring how macromolecular architecture affects the elasticity of a polymeric liquid, we find general rigid bead-rod theory to be both versatile and accurate. This theory sculpts macromolecules using beads and rods. Whereas beads represent points of Stokes flow resistances, the rods represent rigid separations. In this way, how the shape of the macromolecule affects its rheological behaviour in suspension is determined. Our work shows the recent advances in polymer viscoelasticity using general rigid bead-rod theory, including advances applied on the coronavirus. The coronavirus is always idealized as a spherical capsid with radially protruding spikes. However, histologically, in the tissues of infected patients, capsids in cross section are elliptical, and only sometimes spherical. This capsid ellipticity implies that coronaviruses are oblate or prolate or both. We call this diversity of shapes, pleomorphism. Recently, the rotational diffusivity of the spherical coronavirus in suspension was calculated, from first principles, using general rigid bead-rod theory. We did so by beading the spherical capsid, and then also by replacing each of its bulbous spikes with a single bead. In this paper, we use energy minimization for the spreading of the spikes, charged identically, over the oblate or prolate capsids. We use general rigid bead-rod theory to explore the role of such coronavirus cross-sectional ellipticity on its rotational diffusivity, the transport property around which its cell attachment revolves. We learn that coronavirus ellipticity drastically decreases its rotational diffusivity, be it oblate or prolate.


We hope to see you all there!

Kind regards,
Your PGR Committee
