WebFeb 9, 2024 · The proposed Marangoni-propulsion micro-robots integrated with the photonic colloidal crystal hydrogel sensor. a) The schematic image of the sensing and transmitting the environmental information by the color change of the photonic gel sensor while the micro-robots propel. b) The design of the proposed micro-robots. WebJun 17, 2024 · Marangoni flows driven by chemical reactions can sustain themselves via delivery of reagents at the reaction site. Here, it is demonstrated how a flow generated through reactions between a photoacid generator and a surfactant can be maintained for more than 20 minutes at the air-water interface. WebThe resulting outward Marangoni stress enhances droplet spreading. On the other hand, evaporation of H 2 O, the second most volatile component ( VPH2O = 2.3 kPa) with the highest surface tension ( γH2O = 72 mN ⋅ m -1 ), depletes H 2 O in the vicinity of the apparent contact line, thereby decreasing the local surface tension. hott bluetooth cd player
