WebFeb 25, 2024 · To address this challenge, we opted instead for chemical or reactive wetting 12, by exploiting the affinity of both Gallium and Indium to form metal alloying compounds with gold 18,19,20,21,22. Web2 and liquid gallium bulges with a contact angle θ¼23 . On textured substrates, patterned with a hexagonal lattice of round PDMS pillars (height h¼1.5μm, pitch p¼8μm), the dewetting to wetting transition (*) of gallium is defined geometrically by the channel width L. For tan θ>h/L, gallium bulges form on the top of the structure.

WebA Ga wetting layer was used to modify the surface structure of sapphire (0001) substrate to prepare high-quality ZnO film by radio frequency plasma-assisted molecule beam epitaxy. We found that this Ga layer plays a crucial role in eliminating 30° rotation domains, controlling polarity and decreasing defect density in ZnO epilayers, as demonstrated byin … 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 … 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 golden gate chinese buffet
