In a system of N particles, with continuous size polydispersity there exists N(N-1) number partial structure factors making it analytically less tractable. A common practice is to treat the as an effective one component which known exhibit artificial softening structure. The aim this study describe in terms M pseudo species such that we can avoid but at same time have value << N. We use potenti...

Spatially ordered arrangements of spherical colloids are known to exhibit structural colours. The intensity and brilliance these colours typically improve with colloidal monodispersity, low concentrations point line defects increasing refractive index contrast between the embedding medium. Here we show that suspensions charge stabilised, fluorinated latex particles refractive-index their aqueou...

The study aims to analyze the chemical composition of Suaeda aegyptiaca essential oil (PSAE) by GC–MS, produce nanoemulsified (NSAE) using ultrasound, and compare antimicrobial antioxidant activity PSAE NSAE in laboratory medium rainbow trout fish (Oncorhynchus mykiss). Geranyl-acetone (30.52%) p-Vinylguaiacol (10.66%), (e)-β-ionone (7.79%) were main compounds. mean droplet size diameter, polyd...

Objective: The present investigation aims to formulate the ideal drug formulation using different surfactants and optimize amlodipine-loaded polymeric nanoparticles. Methods: work was drug-loaded nanoparticles enhance dissolution rate of a poorly water-soluble drug, amlodipine besylate, anti-solvent precipitation method. Characterisation studies include particle size (nm), Zeta potential (mV), ...

– We study the probability, PS(t), of a cluster to remain intact in one-dimensional cluster-cluster aggregation when the cluster diffusion coefficient scales with size as D(s) ∼ s . PS(t) exhibits a stretched exponential decay for γ < 0 and the power laws t −3/2 for γ = 0, and t−2/(2−γ) for 0 < γ < 2. A random walk picture explains the discontinuous and non-monotonic behavior of the exponent. T...

2014 We consider a linear polymer melt where the chains are made by condensation of bifunctional monomers. In the very large distribution of molecular weights that is obtained one may distinguish typical and very large chains with different behaviours. Screening is effective in the former, which act as a (good) solvent for the latter. The cross-over molecular weight N * between the two classes ...
