“…[107] The important quantity work of adhesion could be used to characterize the intimate contact between the liquid phase and solid phase (Figure 13b). [107][108][109][110][111] This is largely determined by the surface energy of the solid material and the surface tension of the functional liquid, that is, it is the chemistry compatibility between the solid and liquid interface. According to the method of Owens, Wendt, Rabel, and Kaelble (OWRK), the interfacial energy between the solid and liquid can be calculated by forming the geometric mean: [112] 𝜎 sl = 𝜎 s + 𝜎 l − 2…”

Aerogel fibers garner tremendous scientific interest due to their unique properties such as ultrahigh porosity, large specific surface area, and ultralow thermal conductivity, enabling diverse potential applications in textile, environment, energy conversion and storage, and high‐tech areas. Here, the fabrication methodologies to construct the aerogel fibers starting from nanoscale building blocks are overviewed, and the spinning thermodynamics and spinning kinetics associated with each technology are revealed. The huge pool of material choices that can be assembled into aerogel fibers is discussed. Furthermore, the fascinating properties of aerogel fibers, including mechanical, thermal, sorptive, optical, and fire‐retardant properties are elaborated on. Next, the nano‐confining functionalization strategy for aerogel fibers is particularly highlighted, touching upon the driving force for liquid encapsulation, solid–liquid interface adhesion, and interfacial stability. In addition, emerging applications in thermal management, smart wearable fabrics, water harvest, shielding, heat transfer devices, artificial muscles, and information storage, are discussed. Last, the existing challenges in the development of aerogel fibers are pointed out and light is shed on the opportunities in this burgeoning field.

“…With the change of the environment, most living organisms in nature tend to evolve with various functional surfaces for survival, thereby realizing the directional and spontaneous transport of droplets. , For example, the anisotropic micro-grooved structure on the rice leaves allows the surface droplets to directionally roll off, which should be derived from the difference in an energy barrier between the longitudinal direction and the horizontal one. , The hierarchical micro/nanostructures on the wings of butterflies motivate the raindrops to fall easily from their body, thereby enabling the wings to dry and allowing for normal flight. , Owing to the wetting gradient force arising from the conical topography, the well-distributed clusters of conical spines and trichomes on the cactus stem accelerate the efficient fog gathering from the hydropenic ambient. − Based on these impressive phenomena, some great efforts have been dedicated to designing a series of functional surfaces to realize self-cleaning, , water-collecting, − microfluidics, − and biomedical detection. , …”

Multiple-Droplet Selective Manipulation Enabled by Laser-Textured Hydrophobic Magnetism-Responsive Slanted Micropillar Arrays with an Ultrafast Reconfiguration Rate

Biomimetic structures based on the magnetic response have attracted ever-increasing attention in droplet manipulation. Till now, most methods for droplet manipulation by a magnetic response are only applicable to a single droplet. It is still a challenge to achieve on-demand and precise control of multiple droplets (≥2). In this paper, a strategy for on-demand manipulation of multiple droplets based on magnetism-responsive slanted micropillar arrays (MSMAs) is proposed. The Glaco-modified superhydrophobic surface is the basis of multiple-droplet manipulation. The droplet’s motion mode (pinned, unidirectional, and bidirectional) can be readily fine-tuned by changing the volume of droplets and the speed of the magnetic field. The rapid movement of droplets (10–80 mm/s) in the horizontal direction is realized by the unidirectional waves of the micropillar array driven by a specific magnetic field. The bending angle of micropillars can be rapidly and reversibly adjusted from 0 to 90° under the action of a magnetic field. Meanwhile, the liquid-involved light, electric switch, and biomedical detection can be designed by manipulating the droplets on demand. The superiority of MSMAs in multiple-droplet programmable manipulation opens up an avenue for applications in microfluidic and biomedical engineering.
