An oxygen transport ceramic membrane was prepared with La0.6Sr0.4TixFe1–xO3–δ (x = 0.2 and 0.3) oxides which was synthesized by polymerized complex method. In order to investigate the effects of Ti substitutions into lanthanum–strontium ferrites, material property, thermal expansion coefficient, oxy

Zeolite MFI crystal layers were grown on different α-alumina supports. Permeation and separation characteristics of selected zeolite MFI composite membranes were measured for the system of butane isomers. Flux, permeation and separation factors were measured as a function of feed pressure, temperatu

The production of a biosurfactant by Pseudomonas fluorescens Migula 1895-DSMZ was studied. Cultures conditions involving variations in carbon and nitrogen sources and different C:N ratios were examined at constant temperature and pH, with the aim of increasing productivity in the process. Biosurfact

A supported liquid membrane (SLM) contains organic solvent and organic extractant as one organic phase, and a porous support structure. It has been widely investigated for separation and purification of various chemical compounds. SLM has high permeability and selectivity, being regarded as one of t

A La0.7Sr0.3Ga0.6Fe0.4O3-δ membrane with perovskite structure is fabricated by a conventional solid-state reaction. As the oxygen permeation flux of the La0.7Sr0.3Ga0.6Fe0.4O3-δ membrane was lower than commercial gas separation membranes, we coated a La0.6Sr0.4CoO3-δ layer to enhance the oxygen perm
