Scientists at Battelle have developed a tiny bead that not only detects corrosion but delivers a payload to help heal the microscopic cracks that rust creates. Called the Battelle Smart Corrosion Detector, the beads look like a fine, whitish powder that can be mixed with coatings used to protect pipelines and other critical infrastructure subject to corrosion. Self-activating, they release a proprietary chemical that fills cracks.
Of all the electricity generated in the U.S., more than quarter is consumed by lighting. In 2010, North Carolina’s RTI International launched a new product, NLite, intended to help alleviate this burden by improving the reflectance performance of power-intensive lighting devices such as luminaires and liquid crystal displays. The technology, based on nanofiber reflectance polymers, won a 2011 R&D 100 Award.
Washing a car can be a costly and time-consuming chore. The European model of Nissan’s Note will be the first car to wear a new type of paint which could make car washes obsolete. The paint has been engineered to be super-hydrophobic and oleophobic, meaning it repels both water and oils. The tests may result in an aftermarket application.
Winners of R&D 100 Awards must often wait months or even years before the market decides their innovation can become a truly successful product. The editors at R&D follow the fortunes of many these winners, and we are often surprised at the way they can quickly transform entire industries. Recent announcements from R&D 100-winning companies like Newlight, Dow Chemical and Leica Microsystems reflect this level of success.
