Gravity and surface tension both shape yield-stress droplet spreading
—
in EngineeringWhat the study found The study found that the final shape of spreading droplets of yield-stress fluids depends on both gravity and yield stress. In microgravity, the researchers could separate the effects of surface tension from those of yield stress. Why the authors say this matters The authors indicate that microgravity lets them vary two…
ESA microgravity experiments revealed gravity’s effects on soft matter flow
What the study found The review finds that European Space Agency (ESA) microgravity experiments have produced high-precision measurements across several soft-matter systems. These studies showed, among other results, interfacial viscoelasticity, plastic rearrangements in colloidal glasses, roaming bubbles in foams, progressive arrest of droplet motion in emulsions, margination effects in blood cell analogues, and the impact…
