A typical break-up process of a propane liquid bridge (blue) at 185 K in an ambient nitrogen gas (yellow) environment (density of 6:0 kg=m3, with a corresponding partial pressure of 0.36 MPa), recorded in a MD simulation at t=0 (a), 400 (b), 760 (c), and 840 ps (d). The break-up profile is shown in (d), exhibiting a geometry of a long thread pinching on the left. The length of the nanobridge is 30 nm, and its initial average radius is 3 nm.

News In 2000, Georgia Tech researchers showed that fluid dynamics theory could be modified to work on the nanoscale, albeit in a vacuum. Now, seven years later they've shown that it can be modified to work in the real world, too that is, outside of a vacuum. The results appear in the February 9 issue of Physical Review Letters (PRL).

Understanding the motion of fluids is the basis for a tremendous amount of engineering and technology in contemporary life. Planes fly and ships sail because scientists understand the rules of how fluids like water and air behave under varying conditions.
