Study of the Radical Species Induced by Electron-Beam Irradiation in Vacuum on Biomedical UHMWPE

Autor: N. Campo, Laura I. Vagliasindi, Anna M. Visco, Giovanni Tabbì

Publikováno v: International Journal of Polymer Analysis and Characterization. 15:424-437

Ultra high molecular weight polyethylene (UHMWPE) is a component of mobile prostheses. The irradiation performed to sterilize and cross-link the polymer limits its life because of the free radicals originated during this process. In this work, a UHMW

Solubility and Solubility Product Determination of a Sparingly Soluble Salt: A First-Level Laboratory Experiment

Autor: Raffaele P. Bonomo, Giovanni Tabbì, Laura I. Vagliasindi

Publikováno v: Journal of Chemical Education. 89:545-547

A simple experiment was devised to let students determine the solubility and solubility product, Ksp, of calcium sulfate dihydrate in a first-level laboratory. The students experimentally work on an intriguing equilibrium law: the constancy of the pr
