Capillary action of water (polar) compared to mercury (non-polar), in each case with respect to a polar surface such as glass (≡Si–OH). Capillary action (sometimes called capillarity, capillary motion, capillary rise, capillary effect, or wicking) is the process of a liquid flowing in a narrow space without the assistance of external forces like gravity.
The Nature Index attempts to objectively measure the scientific output of institutions, cities and countries by the amount of scientific articles and papers published in leading journals. Differences in quality are taken into account. Only articles published in 82 [note 1] selected quality journals are counted. All these journals are in the ...
The cells that are proliferating are located behind the tip cells and are known as stalk cells. [12] The proliferation of these cells allows the capillary sprout to grow in length simultaneously. As sprouts extend toward the source of the angiogenic stimulus, endothelial cells migrate in tandem , using adhesion molecules called integrins .
Current research in microfluidics is focused on developing point-of-care diagnostics and cell sorting techniques (see lab-on-a-chip), and understanding cell behavior (e.g. cell growth, cell aging). In the field of diagnostics, the lateral flow test is a common microfluidic device platform that utilizes capillary forces to drive fluid transport ...
Various life forms found in nature exploit surface tension in different ways. Hu [8] and his colleagues looked at a few examples to create devices that mimic the abilities of their natural counterparts to walk on water, jump off the liquid interface, and climb menisci. Two such devices were a rendition of the water strider. Both devices ...
Her research extended to investigations of other surface phenomena including capillarity and contact angles. [5] Pockels published 14 scientific papers, mostly in German journals, the last one being published in 1926. [14] She was eventually recognized as a pioneer in the emerging field of surface science. [12]
Figure 1: An example of a porous structure exhibiting capillary condensation.. In materials science and biology, capillary condensation is the "process by which multilayer adsorption from the vapor [phase] into a porous medium proceeds to the point at which pore spaces become filled with condensed liquid from the vapor [phase]."
The following is a partial list of scientific journals.There are thousands of scientific journals in publication, and many more have been published at various points in the past.
