Nikhil Gupta is a researcher at NYU Polytechnic University. He’s also the creator of the latest supermaterial, a metal “foam” so light it can float on water, but also incredibly strong. The new metal is composed of a composite material consisting of a metal matrix, filled with hollow particles known as microballoons. It’s referred to as a magnesium-alloy syntactic foam. Similar materials exist involving aluminium, but this magnesium alloy is 44% stronger and can withstand 25,000 pounds per inch of force! Amazing.
A material such as this has many uses within the lightweight/strong materials sector. Aircraft and car companies alike have put billions into researching lighter, stronger materials. After seeing Gupta’s syntactic foam, the US Military chose to fund his future research.
