  Lightest material: Ultralight Metallic Microlattice sets world record (Video)

IRVINE, CA, USA -- Scientists at UC Irvine, Caltech and HRL Laboratories have concocted the "ultralight metallic microlattice," with a density of 0.9 mg/cc, which is 100 times lighter than styrofoam; made of tiny hollow metallic tubes arranged into a micro-lattice - a criss-crossing diagonal pattern with small open spaces between the tubes, it sets the new world record for the Lightest material, according to World Record Academy (

  The Guinness world record for the lightest known particles in the universe are neutrinos which have a maximum mass of 0.0000000000000000000000000000000 000018 kg. Neutrinos are come in three varieties - electron, muon and tau neutrinos. The mass is an average of the three types.

  Guinness World Records also recognized the world record for the lightest document scanner was set by Docupen, weighing just 49.6g (1.75 oz), released by Planon System Solutions Inc., Mississauga, Canada.
  The new material redefines the limits of lightweight materials because of its unique "micro-lattice" cellular architecture. The researchers were able to make a material that consists of 99.99 percent air by designing the 0.01 percent solid at the nanometer, micron and millimeter scales.

  "The trick is to fabricate a lattice of interconnected hollow tubes with a wall thickness 1,000 times thinner than a human hair," said lead author Dr. Tobias Schaedler of HRL.

  The material's architecture allows unprecedented mechanical behavior for a metal, including complete recovery from compression exceeding 50 percent strain and extraordinarily high energy absorption.

  "Materials actually get stronger as the dimensions are reduced to the nanoscale," explained UCI mechanical and aerospace engineer Lorenzo Valdevit, UCI's principal investigator on the project.

 "Combine this with the possibility of tailoring the architecture of the micro-lattice and you have a unique cellular material."

  Developed for the Defense Advanced Research Projects Agency, the novel material could be used for battery electrodes and acoustic, vibration or shock energy absorption.

 William Carter, manager of the architected materials group at HRL, compared the new material to larger, more familiar edifices: "Modern buildings, exemplified by the Eiffel Tower or the Golden Gate Bridge, are incredibly light and weight-efficient by virtue of their architecture. We are revolutionizing lightweight materials by bringing this concept to the nano and micro scales."
