Molecular modulation in a hollow fiber
Optics Letters, 2006We report the extension of the technique of molecular modulation to a deuterium-filled optical fiber. Using driving lasers at 807 and 1064 nm, each with a pulse energy of several millijoules and a 200 microm diameter fiber with a length of 22.5 cm, we generate 12 sidebands with wavelengths spanning 1.56 microm to 254 nm.

Clinical and Experimental Dialysis and Apheresis, 1981
Hollow fiber dialyzers with a variety of sizes and performance characteristics are presently available for the dialysis of adult patients. We evaluated three currently available follow fiber adult dialyzers in vitro and in vivo during treatment of adult patients. All three dialyzers, Gambro GF-120H, Gambro GF-120L, and Travenol CF-1211 were well suited

Chitosan hollow fiber membranes
Biopolymers, 2003AbstractChitosan hollow fibers were produced by wet spinning, taking advantage of the unique rheological properties of highly viscous chitosan solutions in acetic acid. The mechanical and separation properties of hollow fibers were tested. The mechanical properties were determined by measuring tensile force, tensile stress, elongation, and initial ...

Hollow fiber membrane oxygenator
Journal of Biomedical Materials Research, 1971AbstractHollow fibers have been produced and evaluated for use as membrane oxygenators in an artificial heart device. Gas permeable capillaries now commercially available are unsuitable for this use because of: (1) low percent open cross‐sectional area, (2) large internal diameter, and (3) high cost.

Fiber fuse effect in hollow optical fibers
Optics Letters, 2011We examined nonlinear fiber fuse effect (FFE) in hollow optical fibers (HOFs) that consist of a central air hole surrounded by a high-index ring core and silica cladding. In contrast to conventional solid-core fibers, the HOF with a hole diameter of 4 μm showed high threshold power of 4 W, and resulted in unique tadpole-like voids in periodic arrays ...

Optimum fiber spacing in a hollow fiber bioreactor
Biotechnology and Bioengineering, 1988AbstractA high surface area hollow fiber reactor was developed for mammalian cell culture. The reactor employs an interfiber gel matrix of agar or collagen for cell support. A model was developed to predict cell density as a function of fiber spacing. Optimum spacings are calculated for two sizes of Celgard hollow fibers.

Membrane technology has been successfully applied in many different industrial fields and in some of them, such as desalination, it can be considered a dominant technology. Membranes are produced using a wide variety of techniques which mainly depend on the membrane material employed and on the applications.

Reactive extraction of penicillin G in hollow-fiber and hollow-fiber fabric modules
Biotechnology and Bioengineering, 2000Penicillin G (Pen G) can be rapidly extracted in hollow-fiber liquid-liquid contactors using N-lauryl-N-trialkylmethylamine (Amberlite LA-2) as the extractant. n-Butylacetate is much better than decanol as a diluent for such an extraction, although decanol can give a partition coefficient four times larger.

Solute Removal by Hollow-Fiber Dialyzers
2007Renal replacement therapy performed for end-stage renal disease patients now occurs almost exclusively with hollow-fiber dialyzers. Because renal replacement therapy utilizing such a device requires goals to be set with regard to the rate and extent of solute removal, a thorough understanding of the mechanisms by which solute removal occurs is ...
