American scientists have developed the lightest metal material in the world that can not damage dandelion fluff

this new material is very light, and even if it is pressed on the dandelion, it will not damage dandelion fluff

the twill lattice structure of the new material is very similar to the building structure of the Eiffel Tower in France

how high the lifting device in California can rise; The University of Irvine and Hughes research laboratory recently jointly developed the world's lightest solid metal material, and said that even if this material is pressed on the dandelion, it will not damage the dandelion fluff

99.99% of this new material is air, its weight is 1/100 of polystyrene foam, and its density is only 0.9 mg/cm3. In addition, this material has super pressure resistance, almost completely recovers after being compressed by more than 50%, and has the property of "extremely high energy absorption"

"this new material is made of miniature hollow metal tubes as thin as 1/1000 hair. The metal tubes are cross woven into twill grids, and there are gaps between adjacent grids," Dr. Tobias schedler, who participated in the study, said. In contrast, the structures of other ultralight materials, including silicon aerogel and foam metal, are disordered, which means that their strength, tensile strength, energy absorption and conductivity are worse than those of the raw materials used to manufacture them. This is any combination of the above basic situations

"modern buildings such as the Eiffel Tower in France and the Golden Gate Bridge in the United States, which are built with extremely light materials, have achieved a load-bearing effect that is unexpected because of their unique building structure. We have introduced this concept into nano and micro scales, innovated light materials, and developed this lightest material." William Carter from Hughes research laboratory said

this study has also been published in the latest issue of science for reference to increase the gate size. This new material can be applied to sound insulation, battery electrode, vibration buffer, etc. in the future. The researchers also point out that when the size is reduced to the nanometer range, the properties of these materials will actually become stronger
