Dynamical structure of peptide molecules
Article Abstract:
An investigation is conducted on peptide molecules consisting of a peptide linkage with one or two substituents in the gas phase by Fourier transform microwave spectroscopy, paying special attention to the internal rotation of the substituents relative to the central linkage framework. It is found that, in sharp contrast with the stiff structure around the central C-N bond of the linkage, the internal rotations of the substituents are of low frequency and thus of large amplitude and are extremely susceptible to their local environment.

"Back to the future" --an account discovery of stable quasicrystals
Article Abstract:
This article traces the history of discovery of stable quasicrystals as narrated by the discoverer and the author of the article. Recent advances in the area of binary stable quasicrystals, and ternary stable icosahedral quasicrystals are discussed. Data indicate that the innermost core in the basic cluster of these compounds does not possess an icosahedral symmetry.

Attaching the fluorine atom to organic molecules using BrF3 and other reagents directly derived from F2
Article Abstract:
The different types of fluorination reactions based on the starting point of F2 are discussed. F2 is useful for the completion of perfluorination of various polyfluoroethers whereas the electrophillic acetyl hypofluorite is useful for the introduction of a single fluorine atom into organic molecules.
