[资源] Nature新发的一篇关于硅的研究通讯Dodecagonal tiling in mesoporous silica

文章摘要节选
However, the materials remain far from structurally ideal, in contrast
to their intermetallic counterparts, and fine control over the
structure through a self-organization process has yet to be attained.
Here we use the well-established self-assembly of surfactant micelles
to produce a new class of mesoporous silicas, which exhibit 12-fold
(dodecagonal) symmetry in both electron diffraction and morphology.
Each particle reveals, in the 12-fold cross-section, an analogue
of dodecagonal quasicrystals in the centre surrounded by 12 fans of
crystalline domains in the peripheral part.
