Effective H2 Separation through Electroless Pore-Plated Pd Membranes Containing Graphite Lead Barriers

Spontaneous Assembly of Pore Complex-containing Membranes

Extract prepared from activated Xenopus eggs is capable of reconstituting nuclei from added DNA or chromatin. We have incubated such extract in the absence of DNA and found that numerous flattened membrane cisternae containing densely spaced pore complexes (annulate lamellae) formed de novo. By electron and immunofluorescence microscopy employing a pore complex-specific antibody we followed the...

Effect of Dehydration Temperature on the H2 Separation Potential of Hydroxy Sodalite Zeolite Membranes

The main goal of this work was to synthesize and evaluate the effect of dehydration temperature on the potential application of hydroxy sodalite zeolite membrane. Hydroxy sodalite zeolite membranes were synthesized via direct hydrothermal method onto a tubular alumina support without seeding in a hot air oven. The synthesized membranes were characterized by X-ray diffraction (XRD) and scanning ...

Selective Mass Transport of CO2 Containing Mixtures through Zeolite Membranes

In this work, the main aspects regarding the permeation of mixtures containing CO2 and permanent gases such as H2 , N2 and CH4 through zeolite membranes have been investigated, focusing on the description of the mass transport mechanisms taking place inside the pores. First, a brief overview about the performance of the main zeolite membranes used in gas separation (e.g. DDR, CHA, AEI, FAU, etc...

Pd and Pd-Au nanocatalysts supported on exfoliated graphite for high throughput dehalogenation by nanocomposite membranes

Gas Separation Properties of Mixed Matrix Membranes based on Polyimide and Graphite Oxide

In this work, three different graphene-based materials, namely graphite oxide (GrO), thermally reduced graphite oxide (T-RGrO) and ascorbic acid multi-phase reduced graphene oxide (AMP-RGO), were synthesized and used to produce mixed matrix membranes (MMM) based on Matrimid®5218 for as separation. From the samples produced, a complete set of characterization was performed including XRD, FTIR, T...
