Ion beam analysis of a-C:H films on alloy steel substrate
(2013-10-31)
An a-C:H thin film deposited by plasma immersion ion implantation and deposition on alloy steel (16MnCr5) was analyzed using a self-consistent ion beam analysis technique.In the self-consistent analysis, the results of ...
Calcium hydroxide root canal sealers: Evaluation of pH, calcium ion concentration and conductivity
(1997-12-01)
The calcium hydroxide ionization of four root canal sealers (Sealapex, CRCS, Sealer 26, and Apexit) was studied by measuring conductivity and pH and by conducting atomic absorption spectrophotometry. Samples 6 mm in diameter ...

Degradation of the Oxirane Ring of Epoxidized Vegetable Oils with Hydrogen Peroxide Using an Ion Exchange Resin
(Elsevier Science, 2005-12)
The influence of different process variables (stirring, temperature, hydrogen peroxide concentration, particle diameter and amount of catalyst added) on the oxirane ring-opening reaction caused by hydrogen peroxide (H2O2) ...
pH and calcium ion release evaluation of pure and calcium hydroxide-containing Epiphany for use in retrograde filling
(2011-01-01)
Objective: Hydroxyl (OH-) and calcium (Ca++) ion release was evaluated in six materials: G1) Sealer 26, G2) White mineral trioxide aggregate (MTA), G3) Epiphany, G4) Epiphany + 10% calcium hydroxide (CH), G5) Epiphany + ...
