Comparing amine- and ammonium functionalized silsesquioxanes for large scale synthesis of hybrid polyimide high-temperature gas separation membranes
Radmanesh, Farzaneh; Pilz, Monika; Ansaloni, Luca; Peters, Thijs; Louradour, Eric; van Veen, Henk; Høvik, Dag; Hempenius, Mark A.; Benes, Nieck E. (Peer reviewed; Journal article, 2021)PolyPOSS-imide membranes are promising for separating H2 from larger molecules (CO2, N2, CH4) at temperatures up to 300 °C. Their fabrication involves two steps: interfacial polymerization of POSS and 6FDA, followed by ... -
High-pressure CO2/CH4 separation of Zr-MOFs based mixed matrix membranes
Ahmad, Mohd Zamidi; Peters, Thijs; Konnertz, Nora; Visser, Tymen; Téllez, Carlos; Coronas, Joaquín; Fıla, Vlastimil; de Vos, WM; Benes, Nieck E. (Peer reviewed; Journal article, 2020)The gas separation properties of 6FDA-DAM mixed matrix membranes (MMMs) with three types of zirconium-based metal organic framework nanoparticles (MOF NPs, ca. 40 nm) have been investigated up to 20 bar. Both NPs preparation ... -
Identifying the meta, para and ortho isomers in octa(aminophenyl)silsesquioxane (OAPS) from joint experimental characterizations and theoretical predictions of the IR and NMR spectra
Salimi, Saman; Radmanesh, Farzaneh; Benes, Nieck E.; Pilz, Monika; Brown, David; Neyertz, Sylvie (Peer reviewed; Journal article, 2022)Polyhedral oligomeric silsesquioxane (POSS) compounds are defined by the chemical formula (RSiO3/2)8 with R being an organic fragment. They display versatile features due to the combination of both their stable Si-O-Si ... -
Stability investigation of polyPOSS-imide membranes for H2 purification and their application in the steel industry
Ansaloni, Luca; Saric, Maria; Eric, Louradour; Farzaneh, Radmanesh; Dijkstra, Jan Wilco; Pilz, Monika; Høvik, Dag; Benes, Nieck E.; van Delft, Y; Peters, Thijs (Peer reviewed; Journal article, 2021)In the present work, the high-temperature and long-term hydrothermal stability of novel polyPOSS-imide membranes for high-temperature hydrogen separation is investigated. The polyPOSS-imide membranes are found to exhibit ...
