Progress in the development and integration of fluid flow control tools in paper microfluidics
Elain Fu,Corey Downs +1 more
TL;DR: This critical review is focused on the progress that has been made in (i) the development of fluid flow control tools and (ii) the integration of those tools into paper microfluidic devices.
Journal ArticleDOI
Effect of capillary element aspect ratio on the dynamic imbibition within porous networks.
TL;DR: It is shown that the aspect ratio of a capillary, defined as its length divided by its radius, plays an important role, in combination with the capillary radii themselves, in determining the filling rate of individual elements.
Journal ArticleDOI
The radial capillary
TL;DR: In this article, the radial motion of a liquid which penetrates a thin porous medium on the kinetics of the process is analyzed. But the model is not suitable for the case of infinite liquid reservoirs and it is shown that the rate of penetration into the radial capillary is slower than that into either a cylindrical or a unidirectional flat plate capillary.
Journal ArticleDOI
Penetration of a small drop into a capillary
TL;DR: In this article, the theory of capillary penetration has been extended to include the case of drops of a finite size, and a thermodynamic discussion and a kinetic theory are presented.

Spreading on and penetration into thin, permeable print media: application to ink-jet printing.
Richard C. Daniel,John C. Berg +1 more
TL;DR: A new model based on energy arguments is derived and compared to current hydrodynamic equations used to describe simultaneous spreading and penetration of surfactant-laden drops on thin-permeable media with reference to ink-jet printing and it is found that the model produces good quantitative agreement at the highest concentrations.
