The photophysical properties of 3,3'-dialkylthiacarbocyanine iodides and chlorides were measured in various solvents. It was found that photoisomerization and fluorescence are the major contributors to the deactivation of the excited singlet state; intersystem crossing occurs with only a very low efficiency. In ethano…

Based on experimental and modeling studies, the rate of increase in the martensite start temperature M s for the tetragonal‐to‐monoclinic transformation with increase in zirconia grain size is found to rise with decrease in ZrO 2 content in the zirconia‐toughened alumina ZTA system. The observed grain size dependence…

Films of polytetrafluoroethylene (PTFE) were deposited by laser ablation using the fourth harmonic, at 266 nm, of a Nd-YAG laser. The films are found to be stoichiometric with the correct optical properties. We suggest that UV absorption onsets the pyrolitic decomposition of PTFE leading to a monomer that subsequently…

Abstract It is well known that illite-smectite can form from smectite at elevated temperatures in natural and experimental systems. However, the conversion of smectite to illite-smectite is also found in some natural systems that have never been heated. The present experiments show that illite layers can form from sme…

In the first-order Raman spectrum of amorphous carbon (a-C) there is a low-frequency feature in the 200--900-${\mathrm{cm}}^{\mathrm{\ensuremath{-}}1}$ region. This feature is characteristic of the highly disordered amorphous-carbon materials. We note that the intensity of this feature is very sensitive to the thermal…
