particles within the size range 5–50 nm and it is simple, safe and can produce regularly shaped particles with a narrow size distribution [ 6 – 8 ]. Inverse-emulsion based technique for the synthesis of inorganic particles is based on the assumption that the
1 Introduction Cold Asphalt Emulsion Mixtures (CAEMs) represents producing asphalt mixtures at ambient temperature using asphalt emulsion as binder. Previously, CAEMs were produced with open graded or semi-dense graded mixtures to ensure better
, and the problem of oil-in-water (O/W) emulsions, with a high concentration of water and salts turning out to be an important issue. It is necessary to measure the different sizes of water drops dispersed in crude oil, and to design and evaluate
Abstract
Potassium leakage was studied in liquid membrane systems containing various emulsifiers and compared with emulsion, stability in the storage test. The effects of various parameters upon emulsion stability and the leakage of standard traces are discussed. The transfer of cations can be caused by emulsion breaking, by transport with the specific carrier and/or with surfactants used as emulsifiers. The latter case becomes especially important when hydrophilic surfactants, e.g. ones containing polyoxyethylene chains, are present in liquid membranes. In systems containing hydrophobic emulsifiers the transfer of potassium is relatively low. In each case considered the effect of emulsifiers upon the transfer of the standard tracer should be checked prior to using the leakage test to characterize emulsion stability.

oil ( Rutz et al., 2017 ). However, it is not yet known, how fatty acid composition of the oil mixture and crude palm oil affect the emulsion properties and microencapsulation process. Refined PO is used in food industry as biscuit, cake, shortening
concerning about ABS-co- N-PTMI ( N -p-tolylmaleimide). In this article, heat resistance ABS resin was synthesized by emulsion polymerization of N-PTMI, butadiene-Styrene latex (SB), AN and St. The thermal properties and the molecular mass of the
Abstract
This paper presents some results obtained by Differential Scanning Calorimetry (DSC) for characterizing the phase transition within an emulsion. The dispersed substances are either hexadecane, octadecane, water or binary solution. A non-equilibrium model taking into account the inter-phase heat transfer between the emulsifying medium and the dispersed droplet is proposed and explains the main experimental features.
Abstract
Various double emulsion systems with liquid membranes containing tri-n-octylphosphine oxide /TOPO/, tri-n-butylphosphate /TBP/, KELEX 100® and di-2-ethylhexylphosphoric acid /DEHPA/, as carriers for uranium/VI/ pertraction, were studied. The conditions were found at which the systems are most efficient, comparing with solvent extraction. The use of DEHPA as a membrane carrier with solutions of H2SO4 and H3PO4 encapsulated in the membrane was substanfiated.
Abstract
The determination of the most probable mechanism function and the calculation of kinetic parameters of thermal decomposition of powder emulsion explosives have been achieved by different kinetic equations and different kinetic methods from data non-isothermal SC-DSC curves, DSC curves, and thermal explosion delay curve. The courses which the reaction would follow under adiabatic conditions are predicted.
