A triple-layer composite membrane with porous-dense-porous structure was proposed to develop a high performance membrane reactor. The triple-layer composite membrane consists of a porous Sr0.7Ba0.3Fe0.9Mo0.1O3 δ (SBFM) layer, a dense 0.5 wt% Nb2O5-doped SrCo0.8Fe0.2O3 δ (SCFNb) layer and a porous La0.8Sr0.2MnO3 δ–yttria stabilized zirconia (LSM/YSZ) layer. The porous layers can effectively redu...

Membrane separation technology is widely explored for various applications, such as water desalination and wastewater treatment, which can alleviate the global issue of fresh water scarcity. Specifically, carbon nanotubes (CNTs)-based composite membranes are increasingly of interest due to the combined merits of CNTs and membrane separation, offering enhanced membrane properties. This article f...

There seems some underlying technological interest in recent developments (1-9) in palladium alloy systems because of the possibilities of developing palladium alloys with improved characteristics for use as diffusion membranes for hydrogen purification and allied purposes (10). In addition to the important issues of surface kinetics and membrane thickness, other key factors for improved diffus...

A Chitosan/sucrose/polyurethane composite bio-membrane was prepared by the facile drop coating method. The composite bio-membrane had a porous spongy structure composed of a physical mixing of each component. The water absorbability of the composite bio-membrane increased with increasing chitosan and sucrose contents. Furthermore, the composite bio-membrane with immobilized Aspergillus sojae ex...

In the Hydrogen based economy, distributed power generation systems using fuel cell technology require modularity. This modularity in power generation can be achieved by process intensification of the equipments involved. The water gas shift reaction is an integral part of hydrocarbon based Hydrogen generation and the reaction is kinetically limited and hence occupies the largest volume. Proces...

A valveless electromagnetic (EM) micropump with a matrix-patterned magnetic polymer composite actuator membrane structure was successfully designed and fabricated. The composite membrane structure is made of polydemethylsiloxane (PDMS) that is mixed with magnetic particles and patterned in matrix blocks. The matrix magnetic composite membrane was fabricated using a soft lithography process and ...

A new membrane actuator based on our previous diaphragm actuator was designed and constructed to improve the dynamic performance. The finite element analysis was used to estimate the frequency response of the composite membrane which will be driven close to its resonance to obtain a large stroke. The membrane is made of ferromagnetic shape memory alloy (FSMA) composite including a ferromagnetic...
