By manipulating materials at the atomic scale, scientists from the University of Pennsylvania’s School of Engineering and Applied Science, the University of Illinois at Urbana–Champaign, and the University of Cambridge claim to have created a sheet of nickel that is as strong as titanium, but up to five times lighter. Strong as steel is a cliché, but it’s one that’s true. Steel is so strong and so affordable that it’s hard for the average person to go through their day without seeing tons of it in the form of bridges, vehicles, building supports, and reinforced concrete, just to name a very few examples.
