The in vitro hollow fiber system model has been qualified by the European Medicines Agency as a methodology for use in support of selection and development of antituberculosis regimens. More data are expected to be generated in the future to further characterize its value.

The oxygen permeation performance of Ba0.5Sr0.5Co0.8Fe0.2O3−δ (BSCF) mixed-conducting multichannel hollow fiber (MCMHF) membranes was improved by surface modification via spin-spraying of a La0.6Sr0.4CoO3−δ (LSC) porous layer. At 1173 K, the oxygen permeation flux of the modified membranes was clearly enhanced and reached 9.68 mL·cm−2·min−1, which is a remarkable high value in the field of mixe...

The mathematical equation for Separation of the binary aqueous solution is developed by using the SpieglerKedem theory. The characteristics of a B-9 hollow fibre module of Du Pont are determined by using these equations and their results are compared with the experimental results of Ohya et al. The agreement between these results is found to be excellent. Keywords—Binary aqueous solution, model...

In this paper, a system for efficient removal of carbon dioxide by hollow fiber membranes is proposed. The system is compact, and it is very useful for application in the offshore energy industries. In particular, it is used to removing CO2 from the exhaust of power generation facilities on offshore platforms.The proposed dual membrane contactor contains two types of membranes (polypropylene me...

Hollow fiber membrane offers the advantage to integrate catalytic conversion, product separation and catalyst recovery into a single separation process compared to conventional systems. Polypropylene (PP) hollow fiber membrane is a chemically inert and stable membrane with high potential for enzyme immobilization. The surface properties of polypropylene have been modified by radiation induced g...

Impact and compression after impact properties of plain weave carbon fiber sandwich composites were investigated in this study. Impact tests were conducted on different sample types to obtain information about absorbed energy and force. The different samples consisted of foam filled and hollow honeycomb cores with four layer carbon fiber sheets on one or both sides. The impact and compression a...

Currently in United States, there are no clinically-applicable hollow fiber extracorporeal membrane oxygenation (ECMO) oxygenators available. Therefore, our laboratory is in the process of developing a silicone hollow fiber membrane oxygenator for long-term ECMO usage. This oxygenator incorporates an ultrathin silicone hollow fiber. At this time, a specially-modified blood flow distributor (one...
