1 paź 2023 · While small arthropods are able to take advantage of the water's surface properties to retain air bubbles on their bodies for air-breathing during diving, other small animals face a different surface tension related problem: the inability to move air into their air-breathing organ.
15 lis 2017 · Because the surface tension of water is high enough to support the weight of the spider but with much lower surface tension, ethanol can’t do the same. The high surface tension of water is also the reason why rain comes down as a spherical drop.
Flows driven by surface tension are both ubiquitous and diverse, involving the drinking of birds and bees, the flow of xylem in plants, the impact of raindrops on animals, respiration in humans, and the transmission of diseases in plants and animals, including humans.
6 maj 2022 · EPFL researchers have discovered that symmetry in the human body is influenced by surface tension, the same mechanical phenomenon that allows lightweight insects to walk on water.
13 mar 2014 · But for tiny creatures, surface tension—the force created when water molecules cling together—becomes dominant, allowing insects and other small animals to walk effortlessly over ponds and other liquid bodies.
19 lut 2020 · The surface tension of water provides a thin, elastic membrane upon which many tiny animals are adapted to live and move. We show that it may be equally important to the minute animals living beneath it by examining air-breathing mechanics in five species (three families) of anuran (frog) tadpoles.
In human lungs, surfactants lower surface tension, thereby facilitating breathing (Notter 2000), while water-walking insects exploit surface tension in maintaining water-repellency (Bush et al. 2007). Although these organisms, scales, and applications are disparate; they share common fundamental phys-ical mechanisms.
