Diffusivities and Viscosities of Poly(ethylene oxide) Oligomers†

Ethylene Oxide Homogeneous Heterobifunctional Acyclic Oligomers

It is difficult, if not hazardous and partisan, to rank the top advances of organic chemistry in the last approx. 20 years for their role in the development of this science and adjacent, complementary others. It can, however, be said with certainty that the field of homogeneous (HOHAO) and heterogeneous heterobifunctional acyclic oligomers (HEHAO) [1] of ethylene oxide, through their diversity ...

Surface Adsorption of Polyethylene Glycol and Polyvinyl Alcohol with Variable Molecular Weights on Zinc Oxide Nanoparticles

Polyethylene Oxide (PEO) and Polyethylene Glycol (PEG) Polymer Sieving Matrix for RNA Capillary Electrophoresis

The selection of sieving polymer for RNA fragments separation by capillary electrophoresis is imperative. We investigated the separation of RNA fragments ranged from 100 to 10,000 nt in polyethylene glycol (PEG) and polyethylene oxide (PEO) solutions with different molecular weight and different concentration. We found that the separation performance of the small RNA fragments (<1000 nt) was im...

Viscosities of Liquid Fluorocompounds

In spite of their interest, viscosities of fluorocarbon compounds are scarce, and the available data are unreliable and of poor accuracy. In this work, viscosity measurements of linear, cyclic, aromatic, and R-substituted perfluorocarbons were carried out in the temperature range between (298.15 and 318.15) K using an Ubbelohde viscometer. The experimental results show that fluorinated compound...
