چکیده
Abstract In this paper, viscosity ( η ) of 3-Methylaminopropylamine (MAPA)/3-dimethylamino-1-propylamine (DMAPA) with polyethylene glycol (PEG200) was detected over the range (from 303.2 K to 323.2 K) temperature amine mass fractions in 0.30 0.60) at atmospheric pressure. The dependence on and clarified. On experimental basis, activation energy Ea CO 2 diffusion coefficient D CO2 MAPA/DMAPA-PEG200 non-aqueous solutions were deduced.

Discrimination of two fusogenic properties of aqueous polyethylene glycol solutions.
Investigations on the dose response of cell fusion, induced by ionfree aqueous polyethylene glycol (PEG) solutions, reveal distinct lowest fusogenic PEG concentrations for different permanently growing mammalian cell lines. Part of the requisite PEG can be replaced by carbohydrates, preserving the fusogenity of the solutions. This discriminates two effects of PEG solutions causing cell fusion: ...
متن کاملWater potential of aqueous polyethylene glycol.
Water potential (Psiomega) values were determined for aqueous colloids of four molecular sizes of polyethylene glycol (PEG) using freezing-point depression and vapor-pressure deficit methods. A significant third-order interaction exists between the method used to determine Psiomega, PEG molecular size, and concentration. At low PEG concentrations, freezing-point depression measurements result i...
متن کاملMechanism of activation of the prokaryotic channel ELIC by propylamine: A single-channel study
Prokaryotic channels, such as Erwinia chrysanthemi ligand-gated ion channel (ELIC) and Gloeobacter violaceus ligand-gated ion channel, give key structural information for the pentameric ligand-gated ion channel family, which includes nicotinic acetylcholine receptors. ELIC, a cationic channel from E. chrysanthemi, is particularly suitable for single-channel recording because of its high conduct...
متن کاملFormation of globules and aggregates of DNA chains in DNA/polyethylene glycol/monovalent salt aqueous solutions.
It has been known that giant DNA shows structural transitions in aqueous solutions under the existence of counterions and other polymers. However, the mechanism of these transitions has not been fully understood. In this study, we directly observed structures of probed (dye-labeled), dilute DNA chains in unprobed DNA/polyethylene glycol (PEG)/monovalent salt (NaCl) aqueous solutions with fluore...
متن کاملMagnetorheological and Volumetric Properties of Starch and Polyethylene Glycol Solutions in the Presence of NiO Nanoparticles
The effect of NiO nanoparticles on the rheological and volumetric properties of dilute solutions of starch-NaOH-H2O, PEG400-PEG2000 and PEG400-PEG6000 were investigated. Achieve this aim requires to prepare the stable nanofluids. Therefore, nanoparticles of NiO were added to these solutions and dispersed by a shaker and an ultrasonic bath for making the homogeneous nanofluids. The UV-Vis spectr...
