Low Cu and Ag additions (≤0.10 at%) were found to strongly affect the age-hardening behavior in Al•Mg•Si alloys with Mg+Si>1.5 at%. The hardness increased during aging at 170°C and the formation of β″ precipitates was kinetically accelerated. The activation energy of the formation of the β″ phase...

Molecular models of three amino-functionalized cubic polyhedral oligomeric silsesquioxanes (POSS) have been studied at 293 K using classical molecular dynamics (MD) simulations. These hybrid organic/inorganic systems were all based on the T8R8 form, but they differed by the end-groups of their...

It is important to clearly distinguish the combinations of security testing and security risk analysis depending on whether it is viewed from a security testing perspective or a security risk analysis perspective. The main focus in the former view is security testing in which test objectives are to...
