Systematic set of emulsification experiments is performed to elucidate the role of several factors, which control the process of drop breakup during emulsification in turbulent flow. As starting oil-water premixes we use emulsions containing monodisperse oil drops, which are generated by the method of membrane emulsification. By passing these premixes through a narrow-gap homogenizer working in...
It has been known for a considerable time, e.g. Rachford (1891), that the addition of bile salts increases the rate of hydrolysis of fat by pancreatic lipase. Bile salts could speed up the rate of hydrolysis by activating the enzyme molecule, but since they are surface-active agents and therefore emulsifying agents it is clear that their activating effect could be simply due to an emulsificatio...
RAFT-mediated polymerisation-induced self-assembly (PISA) is used to prepare six types of amphiphilic block copolymer nanoparticles which were subsequently evaluated as putative Pickering emulsifiers for the stabilisation of n-dodecane-in-water emulsions. It was found that linear poly(glycerol monomethacrylate)-poly(2-hydroxypropyl methacrylate) (PGMA-PHPMA) diblock copolymer spheres and worms ...
Many of the retinal cell types in both vertebrate and invertebrate eyes have already been investigated using these techniques. As is well known, this has resulted in the positive identification of the physiologic response of vertebrate photoreceptors and certain other retinal neurons. These results are among the most important in recent visual physiology. As interest in intracellular staining i...
