Determination of Hydrogen in Aluminum
203-821-719Hydrogen gas has a high solubility in molten Aluminum and is readily introduced during processing. Once solidification begins, the solubility decreases approximately twenty-fold, and Hydrogen is forced out of the Aluminum. Although most of the Hydrogen is diffused, a small percentage may get trapped, creating Hydrogen-filled voids. This remaining Hydrogen...Access Determination of Hydrogen in AluminumCharacterization and Comparison of Cocoa from Three Different Geographical Areas
203-821-718Due to its unique, specific organoleptic properties, chocolate may be considered as the most appealing confectionery worldwide.
