A novel time lag method for the analysis of mixed gas diffusion in polymeric membranes by on-line mass spectrometry: Method development and validation
European Union's Seventh Framework Program (FP7/2007-2013) under Grant agreement no. 608490. project M4CO2. CNR/FCT Italian/Portuguese Bilateral Project 2015-2016 "Advanced studies of the transport properties and gas separation by polymers of intrinsic microporosity (PIMs) and Ionic Liquid Gel Membranes via novel methods" and the CNR-CAS Bilateral Agreement 2016-2018 "Innovative polymeric membranes for pervaporation and advanced gas and vapour separations".A novel method to determine the individual diffusion coefficients of gases in a mixture during their permeation through polymeric membranes is described. The method was developed in two independent laboratories, using rubbery Pebax® and glassy Hyflon® AD60X membrane samples as standards, and validated using the Tröger's base containing Polymer of Intrinsic Microporosity, PIM-EA-TB. Monitoring of the permeate composition in real time by a quadrupole mass spectrometer allowed the analysis of the permeation transient for gas mixtures. Two operation modes, either with a vacuum in the permeate and a direct connection to the mass spectrometer via a heated restriction, or using a sweeping gas and a heated capillary sample inlet, give excellent agreement with the traditional time lag method for single gases. A complete overview of the method development, identification of the critical parameters, instruments calibration, data elaboration and estimation of the experimental accuracy are provided. Validation with PIM-EA-TB, shows that the method can also successfully detect anomalous phenomena, related to pressure and concentration dependency of the transport properties, physical aging or penetrant-induced dilation. Rapid online analysis of the permeate composition makes the method also very suitable for routine mixed gas permeability measurements.publishersversionpublishe
Criminal Law Reform: Ethical and Legal Changes in Austrian Society
The Interdisciplinary Program in Law and Religion and the Comparative and International Law Institute co-sponsored a lecture titled, “Criminal Law Reform: Ethical and Legal Changes in Austrian Society.” In light of the recent terrorist activities in the European Union, the Austrian government has focused on hate speech legislation and hate crimes. Dr. Christian Pilnacek, Director General for Criminal Matters in the Federal Ministry of Justice of the Republic of Austria discussed recent Austrian legislation that criminalized hate speech that has a likelilhood of inciting violence. Following Pilnacek\u27s presentation, Dr. Wolfgang Brandstetter, Federal Minister of Justice of the Republic of Austria, discussed how the Austrian government is reforming the penal law system.
