Abstract Precise control of the evaporation multiple droplets on patterned surfaces is crucial in many technological applications, such as anti‐icing, coating, and high‐throughput assays. Yet, complex process well‐defined still poorly understood. Herein, we develop a digital twin system for real‐time monitoring key processes droplet microarray (DMA), which essential parallelization automation operations cell culture. Specifically, investigate nanoliter under different conditions via...
Cahn introduced the concept of wall energy to describe interaction between two immiscible fluids and a solid [J. W. Cahn, J. Chem. Phys. 66, 3667-3672 (1977)]. This quintessential has been successfully applied various wetting phenomena droplet in contact with surface. The usually formulated free results so-called surface composition that is not equal bulk composition. difference leads limited range angles which can be achieved by linear/high-order polynomial energy. To address this issue...
Abstract When a multi‐component fluid contacts arigid solid substrate, the van der Waals interaction between fluids and substrate induces depletion/adsorption layer depending on intrinsic wettability of system. In this study, we investigate behaviors A−B We derive analytical expressions for equilibrium thickness composition distribution near wall, based theories de Gennes Cahn. Our derivation is verified through phase‐field simulations, wherein wettability, interfacial tension, temperature...
Variations from equilibrium Young's angle, known as contact angle hysteresis (CAH), are frequently observed upon droplet deposition on a solid surface. This ubiquitous phenomenon indicates the presence of multiple local surface energy minima for sessile droplet. Previous research primarily explains CAH via considering macroscopic roughness, such topographical defects, which alter effective interfacial between fluid phase and phase, thereby shifting global minimum. One typical example is...
