Harvard Scientists Develop Coating That Protects and Strengthens Steel

A Harvard team discovered that their existing SLIPS(Slippery Liquid Porous Surfaces) technology, designed to repel liquids away from steel, also strengthens the steel it’s coating. Using electrochemical deposition, the team applied a surface layer of rough nano-porous tungsten oxide to small sheets of steel. The rough surface the applied tungsten oxide leaves not only drives off water but also reinforces the steel. Read more here.

Minnesota Department of Transportation is Using Drones to inspect Bridges

In an effort to cut back on time and money the Minnesota Department of Transportation is using drones to inspect the underside of a few bridges. Drones may soon replace the traditional inspection method which utilizes a basket-and-lift inspection vehicle to hang inspectors over the side of the bridge. Some bridges inspections require up to an 11 team inspection crew and a traffic crew. Read more here.
