Invisibility cloak made from Teflon can be created in just 15 minutes September 10, 2013 at 10:54 am
Chinese researchers have succeeded in using a highly novel approach to craft a Teflon-based invisibility cloak in just 15 minutes. The process, called topology optimization, uses computer software to algorithmically and automatically design a material with specific qualities — such as an invisibility cloak. The design, once desired qualities have been achieved, is then produced using a 3D printer or similar computer-controlled manufacturing device.
Graphene aerogel is seven times lighter than air, can balance on a blade of grass April 10, 2013 at 1:34 pm
Chinese material scientists have created the world’s lightest material: A graphene aerogel that is seven times lighter than air, and 12% lighter than the previous record holder (aerographite). A cubic centimeter of the graphene aerogel weighs just 0.16 milligrams — or, if you’re having a problem conceptualizing that, a cubic meter weighs just 160 grams (5.6 ounces). The graphene aerogel is so light that an cube inch of the stuff can be balanced on a blade of grass, the stamen of a flower, or the fluffy seed head of a dandelion (see pictures below).
