ferulic acid (4-hydroxy-3-methoxycinnamic acid), an effective component of medical plant, is a phenolic acid with low toxicity that can be absorbed and easily metabolized in the human body. the solubility of ferulic acid (fa) is very low in aqueous solutions which can cause problem in preparation of pharmaceutical products, but it can easily be dissolved in oil/water interface of nano-emulsions...
The relationship between malathion droplet size (VMD) and degree of damage to 1990, 1K and 2K General Motors paint standards was investigated in the laboratory and field. Laboratory tests indicated a positive correlation between malathion droplet VMD and damage spot size. Laboratory settling chamber tests revealed that size-thresholds of droplets too small to cause visible damage averaged 8 and...
In this study, a polymer dispersed cholesteric liquid crystal (PDChLC) film obtained via a one-step fabrication technique based on photopolymerization of a thiol-acrylate reaction system was prepared and characterized for the first time. The effects of the chiral dopant, the influence of thiol monomer functionality and content on the morphology and subsequent performance of the PDChLC films wer...
Abstract The objective of present study was to evaluate pharmacokinetic parameters of dibudipine Phytosolve after oral administration in rats. The solubility test was carried out to select suitable oily solvent for dibudipine. Phytosolve formulation was prepared with a medium chain triglyceride (MCT) oil (20%), soybean phospholipids (5%) and a 70% fructose solution (75%). The effect of polyol c...
Possible phases in a nematic liquid crystal confined to a spherical submicrometer droplet embedded in a solid polymer are analyzed in terms of a Landau — de Gennes theory. For a droplet with a radial structure we show that the strength of the nematic-polymer interfacial interaction affects the nematic-paranematic (partially ordered isotropic phase) phase transition and may in addition induce a ...
four different types of a single drop dripping down a hole under gravity by lattice boltzmann method
in this paper the dynamic of a droplet on a surface with a hole is investigated under gravitational effect by using lattice boltzmann method. incompressible two-phase flow with high density ratio proposed by lee is considered. cahn’s theory is used to observe the wettability of the surface in contact with liquid and gas phases. several parameters such as contact angle, surface tension and gravi...
20 Aerosol-cloud interactions are affected by the rate at which water vapour condenses onto 21 particles during cloud droplet growth. Changes in droplet growth rates can impact cloud droplet 22 number and size distribution. The current study investigated droplet growth kinetics of acidic and 23 neutral sulfate particles which contained various amounts and types of organic compounds, from 24 mod...
This paper describes a multifunctional semi-closed droplet-array chip coupled with electrospray ionization mass spectrometry (ESI-MS) detection for multiple sample pretreatment and analysis. A novel interfacing method for coupling droplet system with ESI-MS was proposed using a sampling probe-two-dimensional (2D) droplet-array strategy. The 2D droplet-array system was composed of an 8 × 8 micro...
Micron-scale rod-shaped droplets with a range of aspect ratios are produced using extrusion of oil containing a soft wax crystal network to permit shape customization. A physical model of the droplet shape stability is developed based on balancing interfacial stresses with the internal crystal network yield stress. The model predicts the mechanical properties required for particular droplet siz...
