IUTAM Bureau prizes

Three prizes, each consisting of US$500, a certificate, and a plaque, will be awarded by the IUTAM Bureau for outstanding presentations by young scientists (under the age of 35 at the time of the award). One will be awarded in Fluid Mechanics, one in Solid Mechanics and one for the best poster (in either Fluid or Solid Mechanics). The winners will be announced at the Closing Ceremony of the Congress.

The Batchelor Prize in Fluid Mechanics

The Batchelor Prize, sponsored by Journal of Fluid Mechanics, is an award of US$25,000 in recognition of outstanding research in the field of fluid mechanics. The prize is presented every 4 years at the ICTAM congress, the next occasion being in Beijing in August 2012. The recipient of the prize will deliver a lecture at the ICTAM congress and this will also be published in Journal of Fluid Mechanics and be made freely available on the Cambridge Journals website. A selection committee whose members are internationally distinguished in fluid mechanics will award the prize.

G. K. Batchelor was a leading figure in fluid mechanics throughout the latter half of the 20th century. He will be particularly remembered for his pioneering work on homogeneous turbulence, turbulent diffusion, and the dynamics and rheology of suspensions of small particles, areas requiring deep probabilistic thought and methods. There are also many topics in laminar fluid mechanics that bear Batchelor’s imprint and name. He also had an exceptional impact on the field through the institutions that he created: the Department of Applied Mathematics and Theoretical Physics at Cambridge in 1959, which he led for 24 years; Euromech, which he co-founded in the mid 1960s, and chaired for over 20 years; and the Journal of Fluid Mechanics which he founded in 1956, and edited for 42 years! He also served IUTAM as Secretary of its Congress Committee in the early 1960s and as a member of its General Assembly for more than 25 years. It is particularly appropriate that the fluid mechanics prize sponsored by the Journal of Fluid Mechanics should bear his name.

	FULLY DEVELOPED RAYLEIGH-BÉNARD AND TAYLOR-COUETTE TURBULENCE Lecturer: Professor Detlef Lohse Technical University of Twente, the Netherlands
Abstract In this lecture we will summarize our advances in the understanding of turbulent Rayleigh-Bénard convection and turbulent Taylor-Couette flow during the last decade, addressing the progress both in experiments, theory, and numerics. We will also discuss rotating and boiling turbulent Rayleigh-Bénard flow and the drag reduction in bubbly Taylor-Couette flow.

The Rodney Hill Prize in Solid Mechanics

The Rodney Hill prize, sponsored by Elsevier, is to be awarded in recognition of outstanding research in the field of solid mechanics. The prize is to consist of a plaque and a check for US$25,000. The prize is to be awarded every 4 years, to coincide with the quadrennial International Congress of Theoretical and Applied Mechanics (ICTAM). The first prize was awarded at the ICTAM 2008 in Adelaide and the second will be awarded at the ICTAM 2012 in Beijing.

Dr. Rodney Hill is widely regarded as among the foremost contributors to the foundations of solid mechanics over the second half of the 20th century. His early work was central to founding the mathematical theory of plasticity. This deep interest led eventually to general studies of uniqueness and stability in nonlinear continuum mechanics, work which has had a profound influence on the field of solid mechanics – theoretical, computational and experimental alike – over the past decades. Hill was the founding editor of the Journal of the Mechanics and Physics of Solids, still among the principal journals in the field. His work is recognized worldwide for the spare and concise style of presentation and for its exemplary standards of scholarship. It is a fitting tribute that the solid mechanics prize sponsored by Elsevier Ltd. bear his name.

	Probing mechanical principles of cell-nanomaterial interactions Lecturer: Professor Huajian Gao Brown University, USA
Abstract Nanomaterials such as carbon nanotubes, nanowires, nanofibers and graphene have potential applications for next generation microchips, composites, barrier coatings, biosensors, and drug delivery. There is also an urgent need to understand the hazards of nanomaterials to health. In this talk, I will discuss some recent studies at Brown University on the mechanics of cell-nanomaterial interactions, including the mechanics of cellular uptake of nanoparticles by receptor-mediated endocytosis and coarse-grained molecular dynamics simulations of lipid bilayer segments interacting with nanoparticles. The discussions will be organized around the following questions: Why and how does cellular uptake of nanoparticles depend on the particle size, shape, aspect ratio and elasticity? In particular, we will discuss the effect of nanoparticle size on receptor-mediated endocytosis, the effect of elastic stiffness on cell-particle interactions and how cylindrical one-dimensional nanomaterials such as carbon nanotubes enter cells.
