STRUCTURE OF LIPID MEMBRANES AT SOLID/LIQUID AND LIQUID/VAPOR INTERFACES C. M. DeCaro, Ph.D. Department of Physics Northern Illinois University, 2012 Laurence Lurio, Director The study of model lipid membranes is one of the most promising and exciting areas of current biophysical research. The physical processes that occur in a cell’s outer membrane regulate all transport in and out of the cell...

In this research, process asymmetric polyetherimide hollow fiber membranes using ethanol (0, 2 and 4 wt%) as non-solvent additive in the polymer dope via phase inversion method were fabricated. Aqueous solution of 1-methyl-2-pyrrolidine (NMP) (90%) was applied as a bore fluid to avoid inner skin layer formation and water was used as the external coagulant. The morphology of fabricated membranes...

Cellulose acetate (CA) and Tween-20(T-20) are interacted and resulted as a supported liquid membrane system. The membrane potential was measured with uni-uni valent electrolyte, NaCl solutions using saturated calomel electrodes (SCEs).The effective fixed charge density of the membrane was determined by TMS method. Other important electrochemical parameters were calculated. Membrane adsorb-abili...

The novel liquid-infused membranes have been shown to mitigate membrane biofouling. Here, the long-term stability of these tested and analyzed using bacterial growth curve models.
