Two new SiC polytypes belonging to the [(44) n 43]3 structure family

High-resolution electron microscopy and domain structures of pentagonal Frank-Kasper phases

The Laboratory of Atomic Imaging of Solids is dedicated to the direct imaging of materials in various fields of solid-state sciences at the atomic or molecular level. The main programs of this laboratory are briefly described, including quasicrystals, new phases and microdomains in Frank-Kasper phases, suboxides of metals, catalysts, minerals found in China, and molecular structure of organic substances. A recent systematic investigation of domain structures consisting of juxtaposed icosahedral columns is also presented.
