In this study, a three-phase hollow fibre-supported liquid membrane (HF-SLM) technique incorporated with high-performance chromatography (HPLC) coupled diode array detection (DAD) was developed for the extraction, clean-up, and determination of fifteen sulfonamide residues in chicken egg samples. The were extracted from 5 mL sample solution pH 2.5 into thin layer organic phase (1-octanol 10% TO...

In this study, the influence of the salts as an additive on the performance of the membrane was investigated and an extensive work was performed to optimize PVDF hollow fiber membranes through a response surface methodology (RSM). The prepared membranes were characterized by SEM, contact angle and LEP measurement. Then, the RSM was used for the optimization of surface pore size, porosity and hy...

Dual-phase molten salt-ceramic membranes show high permselectivity for CO2 when carbonate is supported in a porous oxygen-ion and/or electron conductor. In this arrangement, the support likely contributes to permeation. Thus, if one understand and ultimately design membranes, it also important perform experiments with an inert where permeation relies upon properties alone. Here, nominally mater...

Although fabrication technologies of Microstructured Optical Fibres (MOFs) fibres have matured at an impressive rate over the past ten years, these fibres are widely perceived as “challenging” and some key issues are still outstanding in order to improve their manufacturability. One such issue revolves around methods to improve structural control during the fibre draw. Structural control is of ...

Bioartificial liver support provides a bridge to transplantation which is at present the only proven specific treatment for acute liver failure. In this paper, a novel multi-coaxial hollow fiber bioreactor so-called "Fibre-in-Fibre FIF Bioartificial liver device" with three compartments is experimentally and mathematically studied. The mathematical model in this paper is an extension of Krogh c...
