Dispersants in Stirred Ball Mill Grinding
KONA Powder and Particle Journal, 2014 The influence of chemical dispersants on the milling of dolomite was examined using a stirred ball mill. The effective degree of grinding was found to depend on the aggregation/dispersion state or the viscosity of ...

Chemical affinity and dispersibility of boron nitride nanotubes
Nanoscale Advances, 2020 The chemical affinity of purified boron nitride nanotubes (BNNTs) is measured in terms of Hansen solubility parameters, taking into account relative sedimentation time in various solvents. This improves predictions for the dispersion of BNNTs.

Corexit-EC9527A Disrupts Retinol Signaling and Neuronal Differentiation in P19 Embryonal Pluripotent Cells. [PDF]
PLoS ONE, 2016 Corexit-EC9500A and Corexit-EC9527A are two chemical dispersants that have been used to remediate the impact of the 2010 Deepwater Horizon oil spill. Both dispersants are composed primarily of organic solvents and surfactants and act by emulsifying the ...
