Researchers at UNC-CH have discovered that carbon nanotubes can bend without breaking and then return to their original shape under large strains. The nanotubes' buckling behavior indicates potential for safer, stronger products, including those used in sports and aerospace materials.
A new study found that even with enforcement of laws banning tobacco sales to minors, many youths continue to easily purchase tobacco products from merchants. The researchers suggest improving compliance by using more effective inspection methods and stricter penalties.
