“ The complexity we have observed in nacre at the nanoscale is quite amazing and seems likely to be a critical determinant of the toughness of the material, ” says Christine Ortiz, associate professor of the Department of Materials Science and Engineering at the Massachusetts Institute of Technology, U.S.A.
„ Pärlmutterkihi struktuuri keerukus on nanoskaalas päris hämmastav ning see näib materjali kõvaduses tähtsat rolli mängivat, ” sõnab abiprofessor Christine Ortiz USA Massachusettsi tehnikainstituudi materjaliteaduse ja tehnika osakonnast.
