Hollow fibre-based after-treatments impregnated with iron and chromium-based oxides (non-PGM) have been tested for residual methane catalytic oxidation under extreme conditions (sulfur concentration 100-times larger than in real conditions), timeframes (1000 h) operating cycles (thermal shocks). The results from this study proven, the first time reported literature, that hollow fibre reactors c...

A simple sample pre-treatment method utilizing hollow fibre supported liquid membrane (HFSLM) was carried out on pharmaceuticals samples comprising of cough syrups (CS1 and CS2) and an antiinflammatory product (AI). The active ingredients targeted in the extraction process were diphenylhydramine (DPH), chlorpheniramine (CPA) [(S)-γ-(4-chlorophenyl)-N,N-dimethyl-2-pyridinepropanamine maleate sal...

Abstract Surface modification of polyvinylidene fluoride (PVDF) hollow fibre membranes through simple chemical treatment is carried out to graft the surface with presence carboxylic acid groups. This provide means for TiO 2 immobilisation in subsequent stages photocatalysis application. The focus this study was identify highest degree grafting order abundant potential sites assembly. Both aceti...

This paper discusses adsorption of estrone to microfiltration hollow fibre membrane from aqueous phase using estrone as the model compounds. The partitioning of estrone between membrane and aqueous phase at equilibrium state, the concept of membrane retention towards estrone caused by adsorption, adsorption kinetics, and the application potential of membrane adsorption have been assessed throug...

polyvinylidene fluoride/polyvinylpyrrolidone (pvdf/pvp) hollow fiber membranes were fabricated by dry-jet wet-spinning process. the correlated effects of the air gap length and pvp concentration ((1) the air gap length effect at the low and high pvp concentration in the dope solutions, as well as (2) the effect of the pvp concentration at the same air gap length) on the cross-section structure ...

For the first time, a ZIF-8 membrane was grown on the inner surface of a ceramic hollow fiber via cycling precursors. The inner-side hollow fiber ZIF-8 membrane exhibits good performance for recovering hydrogen.

Pre-treatment is normally required to reduce or control the fouling of ultrafiltration (UF) membranes in drinking water treatment process. Current pre-treatment methods, such as coagulation, are only partially effective to prevent long-term fouling. Since biological activities are a major contributor to accumulated fouling, the application of an oxidation/disinfection step can be an effective c...

Tuberculosis (TB) remains a major global health problem. Inadequate exposure to TB drugs constitutes one of the main factors underlying suboptimal treatment response and development of resistance, as evidenced by results from: the in vitro hollow fibre model [1]; clinical studies on relationships between drug concentrations and response [2–5]; a pharmacogenetic trial [6]; and a recent meta-anal...

Throughout the last 50 years, many improvements have been made for a more effective oxygenator. A large plate type membrane oxygenator, used by Clowes, and a coil type, used by Kolff, has evolved into the small hollow fiber oxygenator. The complex bubble oxygenator, or rotating disk oxygenator, has become a small disposable bubble oxygenator. The currently available oxygenators are extremely sm...

In this work, methane detection is performed on the 2ν(3) and ν(2) + 2ν(3) absorption bands in the Near-Infrared (NIR) wavelength region using an all-fibre optical sensor. Hollow-core photonic bandgap fibres (HC-PBFs) are employed as gas cells due to their compactness, good integrability in optical systems and feasibility of long interaction lengths with gases. Sensing in the 2ν(3) band of meth...
