The United States developed the world\’s lightest solid material

US scientists have developed the world\’s lightest solid material can be placed on top of a dandelion, but it will not crush the seeds. The new material is made of fine hollow metal tubes, diameter of the metal tube is one thousandth of a human hair, they form a diagonal crisscross pattern, leaving a small intermediate space. The researchers said air gravity of this material is 99.99% by weight of only one percent of polystyrene foam, with a high energy absorption capability. In the future, new materials can be used for producing thermal insulation, sound absorption cell and a series of electrodes, vibrations or shock products. The study conducted by the University of California, Irvine and HRL laboratories, research findings are published in the latest issue of the journal \”Science.\” This represents the strength engineer the new material properties from the gate structure design format. HRL Laboratories – William Carter said: \”The Eiffel Tower or the Golden Gate Bridge and other modern buildings are ideal for building structures with surprisingly lightweight realized through the use of nanostructures, we are revolutionizing lightweight materials to make..\” Research papers lead author Tobias – Adams Charles Spindler said: \”we use a grid structure composed of interconnected hollow tubes with a diameter of the hollow tube of a human hair only one-thousandth of this material. the density is only 0.9 milligrams per cubic centimeter. \”in contrast, the world\’s lightest solid material has been occupying the throne of silicon aerogels density of 1 gram per cubic centimeter. Other materials include airgel and lightweight metal foam including use of random microporous structure, whether it is the strength, hardness, conductivity, or the energy absorbing material is not used and the production thereof. To study the strength of the metal micro-grid structure, researchers be compressed until the thickness is reduced by half. After the load was withdrawn, the material recovers its original shape and height of 98%. With repeated compression strength and hardness of such materials declining, but researchers say almost without any change after further compression. The team members of the Luo Laizuo – Wald Witt said: \”With reduced to nano-scale, the strength of the material actually becomes stronger if at the same time using micro grid structure, you will get a unique microporous materials.\”
