Membrane distillation (MD) is an interesting process for desalination; however high thermal energy consumption remains one of the main obstacles in its widespread adoption. The current study presents multipass hollow fiber membrane modules to improve efficiency MD process. Fundamentally three module designs are considered: conventional shell and tube (fiber) pass (A), 1 multiple passes (B/C) eq...

This study aims to investigate the potential of nanoparticle retention of ultrafi ltration (UF) multichannel hollow fiber membrane. Filtration experiments of fl uorescent silica nanoparticles (NPs) (10 and 100 nm) and CdTe quantum dots (1.5 nm) suspensions were carried out under diff erent operating conditions to analyze the retention rate (RT), the fouling zone and the...

TASAKI, I. AND S. HAGIWARA. (Natl. Insts. Health, Bethesda, Md., and U. California, Los Angeles.) Capacity of muscle jiber membrane. Am. J. Physiol. 188(3): 423-429. 1957 .-Using two or three microelectrodes inserted into single muscle fibers of the toad sartorius, the electric impedance of the muscle fiber membrane was measured with a.c. between 25 and 1500 cps. It was found that the capacity ...

Transparency of the ocular lens depends on symmetric packing and membrane organization of highly elongated hexagonal fiber cells. These cells possess an extensive, well-ordered cortical cytoskeleton to maintain cell shape and to anchor membrane components. Periaxin (Prx), a PDZ domain protein involved in myelin sheath stabilization, is also a component of adhaerens plaques in lens fiber cells. ...

Membrane separation is known as an efficient technique for the oily wastewater treatment. Therefore, in the present study, sulfonated poly (ether ether ketone) (SPEEK) was introduced into the polysulfone (PSF) solution in order to enhance the hydrophilicity and the membrane structure for the oil–water separation. The hollow fiber membranes were fabricated via a phase-inversion process. The memb...

Cell membrane has a critical and vital role in functioning and existence of nerve cells that form central nervous system (CNS) in mammals. Disruption of nerve membrane that normally occurs following an accident injuring spinal cord is known to be the major cause of paralysis. In most occasions, spinal cord injuries are not leading to complete cut in spinal cord fibers but are known to cause cru...

Humidification process is one of the applications of membrane contactor in which partial pressure of a vapor in the gas stream increases. In this study, two different polyethersulfone and polyetherimide hollow fiber membranes were fabricated and characterized by various test methods and their performance in humidification process under different operating conditions was investigated. The PES me...
