Membrane solubilization induced by Triton X-100 (TX-100) was investigated. Different membrane compositions and phase states were studied along the detergent titration. Expected profiles obtained but new information is provided. The fluorescence of nitrobenzoxadiazole (NBD)-labeled lipids indicates that liquid-ordered (Lo)/liquid-disordered (Ld) coexistence barely unaffected at sub-solubilizing ...

Agins, Alan Paul. M.S., University of Rhode Island, 1980. Effects of Liquid Membranes on Gastrointestinal Absorption of Drugs in Rats. Major Professor: Dr. George C. Fuller. A liquid membrane system was investigated as a potential antidotal treatment for acute drug overdose. The effectiveness of orally administered liquid membranes in simulated acute secobarbital, phencyclidine and strychnine p...

Platform chemicals such as medium-chain carboxylic acids (MCCAs) can be produced from organic waste streams via chain elongation in anaerobic mixed-culture bioreactors. A product recovery system is needed to collect MCCAs the bioreactor effluent. Membrane-based liquid–liquid extraction, most commonly used approach, requires suspended solids removal effluent avoid membrane fouling. An dynamic (A...

in this study, based on a biomimetic approach, novel 3d biodegradable porous hybrid scaffolds consisting of chitosan, gelatin, and tricalcium phosphate were developed for bone and cartilage tissue engineering. macroporous chitosan/ gelatin/β-tcp scaffolds were prepared through the process of freeze-gelation/solid-liquid phase separation. the results showed that the prepared scaffolds are highly...

A chimera gene consisting of the ompF promoter, the coding regions for the signal peptide and the NH2-terminal 11 amino acid residues of outer membrane OmpF protein, and the coding region for the major outer membrane lipoprotein devoid of the NH2-terminal 7 amino acid residues was constructed. Escherichia coli carrying the cloned chimera gene produced a hybrid protein with the predicted chemica...

This study represents a first time that perstraction was assessed as process to remove perfluorooctanoic acid (PFOA) from water. In the process, PFOA permeates through membrane water solvent. The used in this polydimethylsiloxane (PDMS). experimental approach included following: (1) measurement of partition coefficients for between and selected solvents; (2) determination solubility diffusivity...

The presence of lignin and its degraded products such as tannin and humic acids is the main reason causing the aerobically-treated palm oil mill effluent (AT-POME) to display colour at the point of discharge. In this work, a hybrid method is developed to treat the AT-POME sample that was conventionally treated by biological method. This hybrid method combines coagulation and nanofiltration (NF)...
