## Abstract The effect of various organic solvents as well as the crystallization conditions on the crystal habit of anhydrous cholesterol have been studied. Both plates and needleβlike crystals can be obtained in a particular solvent depending on the degree of supersaturation of the solution. Howe

Nylon 6,6 (polyamide 6,6) heterogeneously nucleated with ca. 65 ppm calcium fluoride exhibits crystallization behavior and morphology characteristic of much higher levels of nucleating agent. This is shown using differential scanning calorimetry and polarized optical microscopy.
## Abstract The aim of this investigation was to confirm and summarize the corrosion behavior of titanium in saline solution at different pH and fluoride concentration, and to characterize the surface films and the stability of a passive and aged titanium surface using open circuit potential measur
