Under extreme tension, the hydrostatic pressure of the water would display as absolute negative. The comprehension of such a unique thermodynamic non-equilibrium state in the phase diagram of water is still blurry, which has sparked a lot of curiosity in the field. Nevertheless, after botanists discovered it in the xylem of trees first, this so-called negative pressure of stretched water could be designed to generate extremely large pressure differences. It has been employed in a series of advanced heat and mass transfer applications, including the on-chip synthetic tree for continuous water extraction, nanoporous membranes with ultrahigh interfacial heat fluxes, and so on.&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\n Click here for original story, <a href=\"https:\/\/phys.org\/news\/2022-04-deformation-hydrogel-negative-pressure.html\" target=\"_blank\" rel=\"nofollow noopener\">Deformation of hydrogel used to measure the negative pressure of water<\/a>&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\nSource: Phys.org&#013;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Water, unexpectedly, has the potential to withstand a massive stretching force or tension due to its internal cohesive force.
