Researchers modeled the nanocrystal&rsquo;s atomic structure and calculated it to have a stiffness of 206 gigapascals, comparable to that of steel. The crystals measure 3 &times; 5 nm, making them too small to study using light microscopes.</p></div> <div class="og_rss_groups"></div><p><a href="http://machinedesign.com/materials/cellulose-nanocrystals-plant-life-could-lead-stronger-materials" target="_blank">read more</a></p> http://machinedesign.com/materials/cellulose-nanocrystals-plant-life-could-lead-stronger-materials#comments Materials Thu, 13 Mar 2014 16:24:00 +0000 35461 at http://machinedesign.com Investigating Surface Treatments Earlier In the Design Process http://machinedesign.com/materials/investigating-surface-treatments-earlier-design-process <div class="field-deck"> Sponsored by General Magnaplate </div> <div class="node-body article-body">Some engineers try to solve problems with coatings at the point of manufacturing—or even after manufacturing.
