Extraction of nickel and its co-extraction with copper from ammoniacal media into emulsion liquid membrane systems (ELMs) was investigated using LIX 84I as the carrier. Measurement of the solute stripped in the internal phase of emulsion opened a new dimension in the study of the ELM extraction processes. The effect of operating parameters such as feed pH, initial feed concentration, and treat ...

The purpose is to prepare 2% w/v emulsions of dodecafluoropentane, perfluorodecalin, and perfluoroctylbromide and compare them for their ability to absorb oxygen. The oxygen uptake capability and volume expansion of each emulsion and the blank vehicle were evaluated in water at 21 degrees C and 37 degrees C. The average particle size of the dodecafluoropentane emulsion is < 400 nm stored at roo...

Aim of the present study was to characterize the process of atomization and drying of layer-by-layer emulsions containing lecithin (single layer emulsion) and lecithin/chitosan (multilayer emulsion) and the oxidative stability of the spray-dried emulsions during storage. For this purpose, the analysis of the emulsion spray droplet size during atomization by two different atomization devices, i....

Phenol emulsion reassociation technique (PERT) greatly enhances the rate of DNA hybridization in solution over typical hybridization conditions (1) and has successfully been used to accelerate competitive DNA reassociation for performing subtraction based genomic cloning (2-5). PERT is accomplished through the establishment and maintenance of a phenol emulsion, typically by mechanical vortexing...

To compare the antitumor efficacy and safety of transcatheter arterial chemoembolization (TACE) by epirubicin suspension (epirubicin suspension: epirubicin-iodized oil mixture without solution) to that by epirubicin emulsion (epirubicin emulsion: epirubicin-iodized oil mixture with solution), the efficacy of treatment by administration of either an epirubicin suspension or emulsion was examined...

A stable water-in-oil-in-water (W1/O/W2) double emulsion containing in its inner aqueous phase a microbial consortium (60mgprotein L 1 double emulsion) known to degrade methyl tert-butyl ether (MTBE) was prepared. The primary emulsion (W1/O) had a volume disperse phase (f1) of 0.3 and was stabilized with 8% Span 80. The double emulsion had a volume disperse phase (f2) of 0.3 and was stabilized ...

Autoradiographic techniques for use with the electron microscope have been developed and considerably improved in recent years. A review of this historical development is given by Meek and Moses (14), and a theoretical analysis of the problems involved by Pelc (17) and Caro (4). In this paper, we describe a method for preparing autoradiographic specimens, using a new, fine-grained emulsion and ...

This study was conducted to investigate the effects of kimchi powder and onion peel extract on the quality characteristics of emulsion sausage manufactured with irradiated pork. The emulsion sausages were formulated with 2% kimchi powder and/or 0.05% onion peel extract. The changes in pH value of all treatments were similar, depending on storage periods. The addition of kimchi powder increased ...
