Capillary condensation in atomic-scale channels. Courtesy: Zisong Ma, Yan Liang (USTC) When water vapour spontaneously condenses inside capillaries just 1 nm across, it behaves according to the ...

Artery vs Vein vs Capillary. Blood vessels are small tube-like structures that transport blood inside your body. ... They have thick walls and a muscular layer that keeps your blood moving.

If the flow is nonturbulent (laminar), the layers of the fluid that are closest to the centre of the capillary flow faster than the layers near the walls.

As discussed in last month’s article, a capillary tube metering device is found mainly in domestic and small commercial applications and is nothing more than a long, fixed length tube with a very ...

Capillary condensation is a textbook phenomenon and omnipresent in our world. For example, children playing on the beach rely on this universal process to hold their sandcastles together. Despite ...

When the part is subsequently heated, capillary action produced by the tiny channels between the nanotubes creates negative pressure, drawing the layers together. As a result, any air pockets that ...
