A mesoscopic lattice Boltzmann model is implemented for modelling isothermal two-component evaporation in porous media. The based on the pseudopotential multiphase with two components to mimic phase-change component (e.g. water and its vapour) non-condensible dry air), cascaded collision operator used enhance numerical performance. first analysed Chapman–Enskog expansion then validated by theor...

Abstract. Compaction and salinization of soils reduce croplands fertility, affect natural ecosystems, are major concerns worldwide. Soil compaction alters soil structure affects the soil's hydraulic properties, it therefore may have a significant impact on evaporation solute transport processes in soil. In this work, we investigated combined compaction, bare evaporation, salt precipitation. X-r...

Using a pulsed electron beam evaporation in vacuum mesoporous nanopowder CaF 2 with specific surface area up to 60.5 m /g were produced. The effect of annealing different media on the evolution magnetic and texture properties nanoparticles has been studied. For first time, medium magnetization nanopowders was discovered. Keywords: nanopowders, calcium fluoride, ferromagnetism, evaporation.

The effects of cholesterol and Tween 80 on the physical stability of empty liposomes were investigated. Results showed that the physical stability of liposomes, including electrostatic and steric stability, was improved by addition of cholesterol and Tween 80. Liposomes prepared by different methods, thin-film hydration, thin-film sonication, reverse-phase evaporation and freeze-thawing, were t...

: A tapered dielectric waveguide that scans, at constant height, a sample containing a viral capsid is studied by combining a lattice gas model to simulate water meniscus formation and a finite difference time domain algorithm for light propagation through the media involved. Our results show different contrasts related to different water contents and different meniscus orientations. We propose...

Desorption or evaporation is one of the mechanisms for loss of perfluoropolyalkylether (PFPE) lubricants from the surfaces of data storage media. One approach to minimizing PFPE loss to desorption is the use of lubricants with increasing molecular weight or increasing average chain length. In order to understand the effects of chain length on the lubricant evaporation kinetics we have studied t...

Purpose The purpose of the current study was to investigate the effect of microchannel geometry on neuronal cultures and to maintain these cultures for long period of time (over several weeks) inside the closed microchannels of cellular scale dimensions. Methods The primary hippocampal neurons from E-18 rat were cultured inside the closed polydimethylsiloxane (PDMS) microchannels of varying siz...

We prepared the poly(succinimide) (hereafter abbreviated as PSI) microcapsules with antitumor agent showing a pH-responsive release. PSI microcapsules enclosing Irinotecan hydrochloride (CPT-11) were prepared by solvent evaporation method via O/O emulsion system. The obtained PSI microcapsules had a smooth surface and were spherical with diameter of approximately 30 μm. CPT-11 was successfully ...

Aloe plants can be grown autotrophically in a maintenance-free, sterile, ex vitro environment. Excel, 15-5-15 plus minors fertilizer formulation and Plant Preservative Medium (PPM) biocide was used as a very economical basal medium. In vitro micropropagated plantlets were regenerated in Excel media with 2 g /L sucrose and 2.2 μM 6-Benzylamino purine (BA) and used to initiate ex vitro cultures i...
