Imbibition is capillary-driven transport where liquid invades a textured surface favorable to the spreading liquid41. We investigated the wetting behavior of EGaIn on the metal-deposited, microstructured surface in HCl vapor (Fig. 1). Copper was chosen as the metal for the underlying surface. On flat copper surfaces, … See more To investigate the effect of the topographical dimensions of the patterns on the wetting and imbibition of EGaIn, we varied the dimensions of the Cu-coated posts. Figure 2 reports the contact angles and imbibition of … See more Owing to the liquid characteristics of EGaIn, the EGaIn-coated Cu/PDMS (EGaIn/Cu/PDMS) can be used for flexible and stretchable electrodes. Figure 5a compares the change in the resistance of the pristine … See more The imbibition of EGaIn on the post-patterned Cu/PDMS enables the EGaIn patterning via selective wetting (Fig. 4). When EGaIn droplets are placed on the post-patterned region and are exposed to HCl vapor, EGaIn … See more WebApr 21, 2024 · Wetting state transition regulated by surface roughness has increasing importance for its wide applications. Molecular dynamics simulations have been performed to study the wetting state transition …

WebDec 23, 2013 · In this work, we explore the wetting behaviors between droplets of gallium–indium alloys and thin metal films, with an emphasis on tin and indium substrates. We find that metallic droplets reactively wet thin metal foils, but the wettability of the foils may be tuned by the surface texture (produced by sputtering). WebApr 28, 2024 · Minimise the number of containers that the gallium comes into contact with as it will efficiently wet many surfaces – including glass, plastic and skin – and leave a residue that can amalgamate with (ie, form an alloy) and weaken other metals like aluminium and gold. This very thin film is then very difficult to remove. increase in water rates uk

WebAug 6, 2024 · This serves as a wetting seed layer for the subsequent thermal evaporation of a gallium thin film (m Ga = 0.9 mg cm −2) in a vacuum chamber. Upon nucleation on the seed layer, gallium alloys with gold to form a thin, solid intermetallic phase (AuGa 2 ), 33 then fills completely the inter-pillar volume as liquid phase (Figure 1 b). WebAfter eating about 140 g (5 oz) of gallium, it would react with your stomach acids and produce over 300 g (12.5 oz) of gallium trichloride. Not only would it produce this … WebMay 20, 2024 · This work presents a peculiar metallic bond interaction which strongly improves wetting performance and adsorption energy at the liquid Ga/FeGa 3 interfaces … increase in wearable technology
