Since amorphous nanosheets do not have layers, the surfactant layers serve as a substitute. Osada is enthusiastic about the ...

In a crystalline material, such as the UO 2 sample shown, vacancies in the lattice can aggregate to form negative crystals, voids bounded by crystallographic planes. The photograph has a magnification ...

In that sense, polyamorphism is the amorphous analogue to polymorphism in crystals. Common to most polyamorphic materials is the directionality of the atomic bonds. On page 192 of this issue ...
