Calorimetric Measurements of CO2 Absorption into Aqueous -Methyldiethanolamine Solutions

A reaction calorimeter was used to study the rate and heat effects during CO2 absorption into aqueous solutions of N-methyldiethanolamine (MDEA). The experiments were carried out at constant pressure of 0.1 MPa and 0.3 MPa over a range of temperature from 293 K to 333 K. The amine content changed from 10 to 30 mass %. The experimental equipment and procedure were described with the emphasis on ...

Modelling fast mode dielectric relaxation of counterions in aqueous solutions of ionene bromides and fluorides.

The parameters derived from previously published (M. Luksicet al., Macromolecules, 2009, 42, 4337-4342) dielectric spectra of aqueous solutions of aliphatic 3,3-, 4,5-, 6,6-, and 6,9-ionene bromides and fluorides were analyzed within the existing models for the fast counterion-relaxation process. By fitting the Poisson-Boltzmann results to the experimental data for the osmotic coefficients of t...

Magnetorheological 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...
