Coating the inside of glass microtubes with a polymer hydrogel material dramatically alters the way capillary forces draw water into the tiny structures, researchers have found. The discovery could ...

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 ...

Capillary tube systems do not stop the flow of refrigerant after the compressor is shut off by the cycling control. In fact, refrigerant will continue to flow from the condenser to the evaporator ...

Capillary tubes serve as simple, fixed-geometry throttling devices in vapour compression refrigeration systems, creating a controlled pressure drop that drives refrigerant expansion from the condenser ...
