Subtly rough surfaces stay dry even under water, say engineers

On August 18th asked its readers to “imagine staying dry underwater for months. Now Northwestern University engineers have examined a wide variety of surfaces that can do just that—and, better yet, they know why. The research team is the first to identify the ideal ‘roughness’ needed in the texture of a surface to keep it dry for a long period of time when submerged in water. The valleys in the surface roughness typically need to be less than one micron in width, the researchers found. That’s really small—less than one millionth of a meter—but these nanoscopic valleys have macroscopic impact.  Understanding how the surfaces deflect water so well means the valuable feature could be reproduced in other materials on a mass scale, potentially saving billions of dollars in a variety of industries…That’s science and engineering, not serendipity, at work for the benefit of the economy”.

Yarmus Engineering, P.C. is available to to provide consulting, design, and inspection services with regards to keeping structures dry and free from intrusion, as well as keeping surfaces dry and slip-resistant.  Please contact our office if we can be of assistance to you or your clients regarding such matters.

New York disease outbreak traced to poor infrastructure maintenance

On August 6th Gizmodo reported that “the South Bronx is dealing with an outbreak of Legionnaire’s disease, with at least 86 known cases and seven deaths. It’s a medical emergency, but also an infrastructure crisis: The reason this outbreak occurred is a failure to care for the buildings we live and work in…In the Bronx, the bacteria grew in water cooling towers in a cluster of buildings…You probably don’t think about cooling towers often (if ever), and there are many different types—but most of them deal with a building’s air conditioning or water system”.
