kz and permit determination of the activation energy (22 kcal) for step 2. Together with the activation energy (52 kcal) for step 1, one obtains 32 kcal as the heat of dissociation of the C-C bond in CsOz at 1000Β°K. This figure, which at first seems surprisingly low, leads to a reasonable value (f51

The relations between chemical vapor deposition (CVD) parameters and the resultant pyrolytic carbon microstructures have been examined for matrix deposition in fibrous carbon substrates. The parameters considered are temperature (1200-145O"C), pressure (20-630 Torr), C/H ratio (l/4-1/14), total flow
## Abstract The conditions for producing nanocomposite fibers composed of calcium alginate, containing a hydroxyapatite nanoadditive were devised and the rheological, sorptive, and strength properties of these fibers, as well as their porous and supramolecular structure were subjected to analysis.
