The capillary number is the ratio of viscous force to the capillary force
, while Weber number is the ratio of the inertial force to the capillary force
is the creator of a new method of liquid vaporization -- the Capillary Force
The innovative technology utilizes the capillary force
vaporizer, which is about the size of an aspirin tablet and made of ceramic discs.
Gyrolab systems use precise, automated control of centrifugal and capillary forces
to steer liquid flow through nanoliter-scale microfluidic structures contained within Gyrolab CDs, automating the assay workflow.
It will be based on integrating thermoresponsive polymers on top of strongly adsorbing solids, where the temperature gradient generated by asymmetric irradiation will cause imbalanced capillary forces
leading to drop motion.
These microscopic cavities induce capillary forces
that keep sanitizers outside the concave areas.
The tensile stress, which is normally attributed to capillary forces
due to water menisci, either plateaus or decreases over time due to water evaporation or polymer relaxation.
However, capillary forces
alone can induce liquid flow (albeit very low), and this can be an attractive alternative to the complexity of active actuation.
These [micro]-fluidic systems, featured that at least one characteristic dimension is in the range between one and a few hundred microns, this device have found increasing use in a variety of applications fields such as chemical process and bio-technology, drug discovery and life-science to name a few [2-3] Capillary forces
result from the interaction of liquid, gas (air) and solid surfaces, at the interface between them (fig.

Among specific topics are which fractal parameter contributes most to adhesion, the lattice gas Monte Carlo simulation of capillary forces
in atomic force microscopy, new challenges at the nanoscale of the pull-off force and the work of adhesion, molecular mobility and interfacial dynamics in organic nano-electromechanical systems, and the plasma modification of polymer surfaces and their utility in building biomedical microdevices.
