Paper360 - July/August 2014 - (Page 8) case you missed it in TAPPI's weekly electronic newsletter AROUND the industry a papeR MIcRoScope FoR tHe woRld Manu Prakash and his Stanford University students have developed a microscope out of a flat sheet of paper, a watch battery, an LED and optical units. When folded together-origami fashion-the result is a functional instrument with the resolution of 800 nanometers, capable of magnifying an object up to 2,000 times. Costing less than a dollar in parts, it is small enough to fit in a pocket yet extremely durable. It can also project an image on any surface, allowing a larger group of people to view it simultaneously. Its minimalistic design is geared towards applications in global health, field based citizen science and K12-science education. Prakash hopes that because Foldscope is so cheap to manufacture and easy to assemble, that everyone will have access to the world of microscopy. SMaRt NaNo beadS detect aNd RepaIR coRRoSIoN Using nanotechnology, scientists as Battelle, Columbus, OH, USA, have developed a tiny bead that not only detects corrosion but also helps heal the microscopic cracks that rust creates. The Smart Corrosion Detector beads look like a fine, whitish powder that can be mixed with coatings used to protect pipelines and other critical infrastructure subject to corrosion. The self-healing smart beads detect and reveal corrosion forming on metal before it is visible to the naked eye. Once activated, the 20 to 50 micron beads release a proprietary chemical that fills the cracks. papeR RecYclING doubleS SINce 1990 A total of 63.5 percent of paper consumed in the U.S. was recovered for recycling in 2013, according to a report by the American Forest and Paper Association. The annual paper recovery rate has nearly doubled since 1990, and the industry has set a goal to exceed 70 percent paper recovery by 2020 as part of its Better Practices, Better Planet 2020 sustainability initiative. 8 Paper360º JULY/AUGUST 2014 GeoRGIa-pacIFIc HelpS toRNado VIctIMS Employees from Georgia-Pacific's consumer products operations in Crossett, Ark., and Muskogee, Okla., USA, loaded six tractor-trailers with bath tissue and paper towels destined for relief agencies working onsite in communities in Arkansas and Mississippi recently damaged by devastating tornadoes. NaNoSpoNGe could cleaN up MajoR SpIllS A new nanosponge from Empa Wood Research, Switzerland, may help clean up future oil spills. In an oil spill, a typical sponge will absorb water along with oil, sink underwater and lose most of its absorption capabilities. To prevent this, Empa researchers modified the chemical properties of nanocellulose by admixing a reactive alkoxysilane molecule into the gel before freeze drying. As a result, the sponge will no longer absorb water and can float on the surface where it will bind with any type of oil.
