Chromocapillary effect

WebDec 28, 2024 · The total angular momentum of massless photons can be divided into spin angular momentum (SAM) and orbital angular momentum (OAM) ().More than 100 y ago, Poynting reasoned that the SAM, defined as S = ±ħ (ħ is the reduced Planck constant), is related to the left- and right-handed circular polarizations.However, only nearly three … WebThe surface tension gradient caused by the photothermal effect also works via propulsion and drives oil motion at the liquid-liquid interface (known as the chromocapillary effect); even the deformation of polydimethylsiloxane membranes can facilitate directional liquid transport . A stronger photothermal effect results in plasmonic heating ...
