chemical bondingThe FP-LMTO calculations of dimers (C 59N) 2, (C 59B) 2, (C 59NB), hydroazafullerene C 59NH and hydroborofullerene C 59BH have been made to specify the ground state geometry, parameters of the electronic structure and bonding energies. The boron atom introduced in the ...
chemical bonding characterThe atomic structure, energetics and chemical bonding state of pristine and Y doped Σ13, (104) grain boundaries in α-Al2O3 were investigated by aberration-corrected Z-contrast scanning transmission electron microscopy combined with first-principles calculations. Combining ...
ATOMIC STRUCTURE: WHAT DO ATOMS LOOK LIKE? Atoms and molecules are small. If a bb was an atom and a marble was a small molecule then you would be the size of North America! Atoms (and molecules, which are made from atoms) are about 10 -10 meters. But what do they look like? The...

The macroscopic properties of many materials are controlled by the structure and chemistry at grain boundaries. A basic understanding of the structure-property relationship requires a technique which probes both composition and chemical bonding on an atomic scale. High-resolution Z-contrast imaging in th...
