Stabilization of coal-water suspensions [PDF]

MATEC Web of Conferences, 2021
In this paper, the effect of sodium lignosulfonate and sodium carboxymethyl cellulose on the stability of a water-coal suspension was studied. As a result, the viscosity of the water-coal suspension was 0.01-0.08 P∙s. The change in dynamic shear rate was

Structure of sodium carboxymethyl cellulose aqueous solutions: A SANS and rheology study [PDF]

Journal of Polymer Science Part B: Polymer Physics, 2014
ABSTRACTWe report a small angle neutron scattering (SANS) and rheology study of cellulose derivative polyelectrolyte sodium carboxymethyl cellulose with a degree of substitution of 1.2. Using SANS, we establish that this polymer is molecularly dissolved in water with a locally stiff conformation with a stretching parameter .

Stabilization of low-cost phase change materials for thermal energy storage applications

iScience, 2023
Summary: Sodium sulfate decahydrate (Na2SO4.10H2O, SSD), a low-cost phase change material (PCM), can store thermal energy. However, phase separation and unstable energy storage capacity (ESC) limit its use.
