Phase inversion emulsification: Current understanding and applications

Advances in Colloid and Interface Science, 2015
This review is addressed to the phase inversion process, which is not only a common, low-energy route to make stable emulsions for a variety of industrial products spanning from food to pharmaceuticals, but can also be an undesired effect in some ...

Phase Inversion of Ellipsoid-Stabilized Emulsions

Langmuir, 2021
The efficacy of anisotropic particles in Pickering emulsion stabilization, attributed to shape-induced capillary interactions, is well-documented in the literature. In this contribution, we show that the surface of hematite ellipsoids can be modified in situ by the addition of oleic acid to effect transitional phase inversion of Pickering emulsions ...

On the phase factors in inversions

Il Nuovo Cimento, 1959
The phase factors which can appear in the definition of the inversions,C, P, T and their products are discussed. It is shown that because of the existence of « physically equivalent » Hamiltonians, the phases inC, CP, T andTP for complex fields are unmeasurable.

Inversion and the phase problem in specular reflection

Physical Review B, 1996
The Marchenko inversion method is employed to determine the scattering-length density profile from the reflectivity for a number of realistic cases. Phase information is obtained via a logarithmic dispersion relation connecting the reflection phase with the reflectivity. The remaining ambiguities to be resolved by phase measurements are analyzed. Their

Cathode Phase Inversion

Review of Scientific Instruments, 1938
Application of cathode phase inversion previously described is made to several practical circuits including symmetrical cathode-ray oscillograph amplification, high fidelity d.c. amplification, and differential or mixer amplifier operation. The theory of a symmetrical degenerative attenuator modification of the basic circuit is developed and practical ...

Mixed Phase Inverse Filter And Deconvolution

11th International Congress of the Brazilian Geophysical Society, 2009
An important problem in seismic data processing is to improve the temporal resolution and to estimate the white reflectivity series (spiking deconvolution). Minimum phase filter is normally applied like conventional procedure in the deconvolution of seismic data. The deconvolution sometimes produces a poor result because the natural wavelet estimate is

Nanoemulsion Formation by Phase Inversion Emulsification:  On the Nature of Inversion

Langmuir, 2006
Emulsification processes are usually characterized by the way they allow the surfactants, as well as the dispersed phase, to be incorporated into emulsions. A model cyclohexane-in-water emulsion using a pair of polyoxyethylene nonylphenyl ether surfactants, one oil-soluble and one water-soluble, was considered.

Inverse 2D phase change problem

1994
Numerical resolution of a 2D inverse phase change problem has been proposed. Two different methods have been tested. The first one use a sequential minimisation procedure, on a sliding time horizon. The second one is based on the transformation of the initial non linear phase change problem in a linear one, which is solved by linear quadratic optimal ...

Causal inversion of nonminimum phase systems

Proceedings of the 40th IEEE Conference on Decision and Control (Cat. No.01CH37228), 2002
Inversion of nonminimum phase systems is a challenging problem. The classical causal inverses proposed by Hirschorn (1979) result in unbounded solutions to the inverse problem where the zero dynamics axe unstable. Stable inversion introduced by Chen and Paden (1992) obtains bounded but noncausal inverses for nonminimum phase systems.

Phase separation and phase inversion of polyurethane networks

Journal of Polymer Research, 1996
A series of polyurethane networks were prepared from MDI (4,41-diphenyl methane diisocyanate), ethylene glycol and a polyoxyethylene-tipped polyoxypropylene triol. The phase separation and phase inversion phenomena of these polyurethane networks were investigated by differential scanning calorimetry (DSC), dynamic mechanical analysis (DMA) and ...
