Effect of physicochemical aging conditions on the composite-composite repair bond strength.

The journal of adhesive dentistry, 2007
This study evaluated the effect of different physicochemical aging methods and surface conditioning techniques on the repair bond strength of composite. It was hypothesized that the aging conditions would decrease the repair bond strength and surface conditioning methods would perform similarly for the repair of resin composites.Disk-shaped resin ...

Physicochemical Controls on the Compositions of the Earth and Planets

Space Science Reviews
Abstract Despite the fact that the terrestrial planets all formed from the protoplanetary disk, their bulk compositions show marked departures from that of material condensing from a canonical H 2 -rich solar nebula. Metallic cores fix the oxygen fugacities (

Composition and Physicochemical Characterization of Walnut Flour, a By-product of Oil Extraction

Plant Foods for Human Nutrition, 2021
The by-product of walnut oil (Juglans regia L.) extraction is a press cake rich in polyunsaturated fatty acids and other bioactive compounds. From this cake, walnut flour is obtained by a milling process. The composition and a physicochemical characterization of walnut flour was performed: proximal composition, mineral content, and fatty acid and amino
