Membranes of the glassy polymer polybenzimidazole (PBI) were formed and tested at temperatures above 300 °C. The membrane formation method provides a rapid screening technique for the evaluation of polymeric systems at elevated temperatures. The rig

We report on the development of membranes with an ultra-thin hydrophobic layer that can be used to support a liquid membrane or serve as a selective gate without further modification when the pore size is small enough. We use a thin layer of gold dep

Effective membrane structures often rely on the presence of thin discriminating layers that exert selectivity control while maintaining high fluxes. Characterizing these separating layers is often difficult given the scarcity of analytical tools capa

Trapping of tritium on polymers with specific functional groups was investigated as a means of treating waste streams containing low levels of tritium. Chemical exchange of tritium with hydrogen on...

A novel multilayer metal membrane has been developed that can be used for the separation of ultra-high purity hydrogen from impure feed streams. The membrane is comprised of very thin layers of dense palladium film deposited on both sides of a thin G

The fabrication of a composite metal membrane using vapor deposition techniques is reported. Commercially obtained tantalum foils are cleaned by ion milling and subsequently coated with palladium metal. The test foil was 13 μm tantalum sheet coated

Highly crystalline SrRuO3 (SRO) and La0.5Sr0.5CoO3 (LSCO) thin films were deposited on Pt/MgO(100) by pulsed laser deposition. The films were mainly (001) textured normal to the substrate surface with a high degree of in-plane orientation with respec

Using magnetic and magnetotransport measurements, we show that a ${\mathrm{YBa}}_{2}$${\mathrm{Cu}}_{3}$${\mathrm{O}}_{7}$ thin-film sample has a single irreversibility line (IRL), which is the same as the vortex-glass-transition phase boundary. Resu
