Abstract Microparticles immersed in a low‐temperature plasma acquire strong negative charges and thus repel each other. Nevertheless, effective attraction between the microparticles such complex can occur due to interplay fluxes of ions microparticles. Here, we report observation droplets formed during parabolic flight, explain their formation terms ion drag force that sustains droplet. We have...

The Eocene-Oligocene Sarbisheh volcanic complex is a part of the Lut-Sistan Zone that outcrops in eastern Iran. In the east of this complex, three groups of volcanic rocks (i.e., andesite, dacite, and rhyolite) exist. Plagioclase as the main mineral of these rocks is found with varying micro-textures. Based on a changing trend in the concentration of anorthite, the developed micro-textures (coa...

a competitive spectrophotometric method has been used for the study of complexation between cu2+, zn2+ and cd2+ (m) and 18-crown-6(18c6, b) in methanol using 4-(2-thiazolylazo) resorcinol (tar, hl) as the colorimetric complexant. absorption spectra of the species in the m-tar-18 c6 system at a various concentrations of 18c6 showed no formation of ternary complex, mlb, and the stoichiometry of t...

using uv-vis spectrophotometic method, the formation constants for interaction of cd2+(aq) andco2+(aq) ions with l-alanine were experimentally studied at ph = 4.1 ± 0.01 (50mm of potassiumhydrogen phthalate buffer), ionic strength of 0.1m potassium nitrate and at 5 differenttemperatures 15,20, 25,30 and 35°c. the optical absorption spectra of mixtures containingconsidered cations and l-alanine ...

The oxidative modification of low density lipoprotein (LDL) may play an important role in atherogenesis. Antioxidants that can prevent LDL oxidation may act as antiatherogens. Our understanding of the mechanism of LDL oxidation and factors that determine its susceptibility to oxidation is still incomplete. Copper is a candidate for oxidizing LDL in atherosclerotic lesions. The binding of copper...
