Impact of a compound drop on a dry surface
WitrynaCannabidiol, aka CBD, is a fat-soluble compound that does not dissolve well in water. To improve the absorption of our CBD oils, gummies, and capsules, we use a process called nanoemulsion. This technology breaks down the CBD particles into a smaller size, making them easier for your body to absorb and use. Where you get your CBD … Witryna12 paź 2011 · R. H. Chen, M. J. Kuo, S. L.

This decrease is explained by the lower kinetic energy of the drop, but also amplified by the formation of a vertical jet emerging from its center, and a relative increase in the viscous dissipation.
