Scientists from the U.S. DOE’s Brookhaven National Laboratory have discovered that drops of liquid with thicknesses of just a few billionths of a meter, or nanometers, are shaped differently than macroscopic liquid drops. Their results, published in the February 9, 2006, online edition of Physical Review Letters, help elucidate the behavior of nanoscale amounts of liquid and, as a result, may help advance several developing nanotechnologies.
