Summary: Water scarcity is a global issue that hinders agricultural productivity and development projects. Converting atmospheric air to drinking water is an important solution. Research shows that a 60 degrees inclination angle is the most efficient orientation for water collection, surpassing 30 and 45 degrees angles. To improve collection efficiency, atmospheric moisture should be collected promptly from functional surfaces.

Summary: Researchers propose a temperature gradient-induced strategy to enhance fog collection. This strategy increases fog droplet collection efficiency and surface refreshing frequency through thermophoretic forces generated by temperature gradients. Scattering measurements show that the movement velocity of fog particles near cooling surfaces is increased by approximately 150%. This work offers a new approach for designing next-generation fog-collection devices and manipulating particle motions.

Summary: In this study, an optimization strategy based on wettability combination and fork-row arrangement is proposed to broaden the effective working range of fog collectors for different concentrations of fog. The results showed that a hydrophilic surface works better in light fog, while a hydrophobic surface has a higher collection rate in heavy fog. The combination of different wettability surfaces performed best in different fog concentrations. Changing the arrangement from smooth-row to fork-row significantly improved the collection rate. The layer spacing also influenced the fog collection performance.

Summary: This study presents a simple and scalable approach using laser-induced graphene (LIG) and a locally inert atmosphere to control the wettability of a polyimide/LIG surface, achieving a transition from hydrophilic to superhydrophobic (∼160°). The wettability of LIG is influenced by the amount of oxygen on its surface, which can be adjusted by the local atmosphere. The effect of LIG surface roughness on wettability is also investigated, and the combination of surface chemistry and roughness is discussed. The proposed processing allows for continuous tuning and patterning of LIG surface properties, making it useful for lab-on-chip applications.

Summary: The wicking dynamics of total wetting liquid in graphene nanocapillaries were explored, and two regimes were identified: inertia-dominated initial spreading and viscous spreading with an exponent greater than Tanner's law. The advancing motions of both the precursor film and main flow were observed, and their lengths were proportional to the square root of time. However, the proportional constant of the precursor film was greater than that of the main flow, and it decreased with increasing channel widths. The thickness of the precursor film and the diameter of curvature of the menisci increased with increasing channel widths, and rapid imbibition behavior was observed in very narrow nanoslits.

Summary: The thermal instability of silver nanowires leads to increased electrical resistance in AgNW networks. Understanding the relationship between structural and electrical properties of AgNW networks is crucial for their integration as transparent electrodes in flexible optoelectronics. In situ X-ray diffraction measurements were used to study the crystallographic evolution of Ag-specific Bragg peaks during thermal ramping, revealing differences in thermal and structural transitions between bare and SnO2-coated AgNW networks.
