Researchers are still busy trying to understand some of the CNT basics, for instance something as fundamental as "how do nanotubes grow"? How can their various properties – electronic, transport, or ...

When you water plants, you water their roots. But how does the water travel all the way from the roots of the plant to the leaves? They are standing upright: wouldn’t that defy gravity? In fact, there ...

This close-up image shows water from a droplet moving into a narrow glass tube that has been coated on the inside with a hydrogel material. Disclaimer: AAAS and EurekAlert! are not responsible for the ...

IF a capillary tube, A, Fig. 1, with a wedge-shaped cut in it at a distance of about 10 mm. from its upper end, at right angles to, and deep enough to make a breach in one side of its aperture, is ...

In the late 1910s and early 1920s a pair of scientists independently developed an equation that describes how a fluid rises in a capillary tube as a function of time. The formula—the Lucas-Washburn ...

Researchers previously thought tube-like channels in their tongues sucked up fluid by capillary action. But the new analysis shows that their tongues actually trap nectar by curling around it. With ...
