Talk: “Approach to Nanofluidics: Fundamentals, Experiments and Applications” by Prof. Kamil Ekinci, Boston University, UNAM Conference Room, 3:40 PM February 12 (EN)

Dear Colleagues and Students,

You are cordially invited to UNAM Nanocolloquium seminars focusing on advancements in the field of nanoscience and nanotechnology. The seminars bring us the most recent developments in these exciting fields.

The 2nd talk of this term will be presented by Prof. Kamil Ekinci*
Title: Approach to Nanofluidics: Fundamentals, Experiments and Applications

Date: February 12, 2016 (Friday)
Time: 15:40
Place: UNAM Conference Room

ABSTRACT – Fluid flows in or around modern nanodevices can attain extreme parameters. In this parameter space, the Navier-Stokes equations, which describe everyday fluid dynamics and are perhaps the most important set of equations in all of engineering, can sometimes fail. The failure of the Navier-Stokes equations in nanodevices can take place via different physical mechanisms: for instance, the continuum hypothesis may break down due to a size effect; or the local equilibrium may be violated due to the high rate of strain. In this talk, I will first introduce the Navier-Stokes equations and describe a framework for understanding how they break down in nanoflows. I will then present our intuitive experiments based on nanomechanical resonators (shown in SEM image), which provide a rigorous test for the fundamental ideas. In the approach to nanofluidics, a single dimensionless scaling parameter, which combines length and time scales in the flow, emerges as the dominant scaling parameter. This parameter may be of relevance for understanding and predicting a number of other nanoflows of technological importance.
