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...

Numerous types of hydrophilic polymer nanoparticles (NPs) have recently become research hotspots because their ability to dissolve in water and can be adapted with respect physical, chemical, biological properties meet the requirements different applications. Synthetic polymeric NPs had successfully gained much attention unique physicochemical properties, such as low toxicity, biodegradability,...

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...

While transport in conjugated polymers has many similarities to that in crystalline inorganic materials, several key differences reveal the unique relationship between the morphology of polymer films and the charge mobility. We develop a model that directly incorporates the molecular properties of the polymer film and correctly predicts these unique transport features. At low degree of polymeri...

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 ...

The mixing Gibbs energy ∆gm for the flower-micelle phase of amphiphilic random and periodic (including alternating) copolymers was formulated on the basis of the lattice model. The formulated ∆gm predicts (1) the inverse proportionality of the aggregation number to the degree of polymerization of the copolymer, (2) the increase of the critical micelle concentration with decreasing the hydrophob...

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...

The kinetics of the equilibrium anionic polymerization of some cyclic siloxanes is modelled by using neural networks. Feedforward neural networks with one or two hidden layers have been used to appreciate the rates of disappearance of octamethylcyclotetrasiloxane and aminopropyl disiloxane at different catalyst concentrations (direct modelling). Alternatively, another neural model has been deve...
