Wetting Property

Fourier transform infrared spectroscopy was used to investigate the chemical structure of down fibers in this paper. Contact angle was calculated to determine the wetting property of down. Experiments demonstrated that the surface chemical structure affected the fiber wetting property strongly. The surface substance by FTIR was forecast to be the mixture of sterol and triphosphate ester. After Soxhlet-extracted the fibers contact angle increased greatly.

The Status

A two-sided wooden icon from a monastery in Transylvania was submitted for multidisciplinary investigations involving X-Ray Fluorescence, Radiographic Photographyand Fourier Transform Infrared Spectroscopy. The most important part of the icon is St. Nicholas wooden icon, painted over forty years ago. The spectroscopic methods used revealed the painting materials composition, the status of the wooden stage, and the presence of resins as varnish (Fourier Transform Infrared Spectroscopy). On one side, the St Nicholasicon was painted over an old icon, St. Arch. Michael, which was evidenced by X-Ray Photography. The obtained data can serve for the preservation and the restoration of these wooden icons.
