• Resumen

  • The article discusses a method devised by researchers at the University of Rochester, New York, which is published in the June 2, 2009 issue of “Applied Physics Letters,” to make a liquid at room- temperature flow against gravity. The team used a high-intensity laser with tiny channels etched in a metal plate. The plate was held vertically and methanol was pulled up the channels by evaporation and capillary action in a process called passive transport.
