Summary: This study investigates how microridges on cactus spines affect the movement of droplets on conical fibers. Microridges were found to reduce the base radius and contact area of droplets, increasing driving force and reducing friction force. Introducing a triple concave cross section to mimic microridges resulted in higher droplet velocity and distance traveled compared to traditional circular fibers.

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: Inspired by Tillandsia and cacti, three types of fog collectors with different bifurcation structures that are not affected by the direction of fog flow are designed. Sample 3 has a fog collecting efficiency 2.26 times that of the modified cylinder, and even close to 0.9 g/h∙cm². Additionally, sample 3 has a fog collecting efficiency 12.17 times that of the unmodified cylinder. Moreover, the sample can maintain a high fog collecting level after ten fog collecting cycles.

Summary: Creating durable hydrophobic coatings with nano-scale thickness remains challenging, but by developing artificial lipid-like interfaces using fluorine-carbon molecular chains, high stability can be achieved. These interfaces exhibit high adhesion in wet conditions, maintaining coating integrity and improving condensation heat transfer efficiency.

Summary: The dynamics of fog droplets depend on size, chemical composition, RH, and turbulence. A new setup was developed to remove fog droplets and quantify RH, with results showing differences in DSD at different RH levels. The study partially confirmed the Kohler theory regarding droplet sizes at different RH levels.

Summary: This paper investigates the charging of particles with diameters of tens of microns at atmospheric pressure, with a focus on ambipolar charging. The study of ambipolar charging in atmospheric pressure plasmas, specifically of droplets, has not been extensively explored. The activation of droplets in plasmas is of interest for various applications such as water purification, fertilizer production, and materials synthesis. The transport dynamics of water droplets through an atmospheric pressure radiofrequency glow discharge sustained in helium are studied. The differential charging of droplets in the plasma gradients of the bounding sheaths is found to be responsible for the transport dynamics.

Summary: Passive droplet manipulation can be achieved by creating a wettability gradient on surfaces, and 3D numerical simulations were performed to analyze droplet motion on a broad range of wettability gradient surfaces. The droplet shape at a particular non-dimensional time was found to be identical on different surfaces, despite being at various locations at a fixed time. Further exploration into the physics behind this identical droplet shape formation is proposed, along with a correlation for the dependence of this phenomenon on various geometrical parameters and fluid properties.

Summary: The study investigates size-resolved turbulent fluxes of fog droplets above a subtropical montane cloud forest in Taiwan. Different flux directions for droplets of varying diameters are observed, with a trimodal log-normal distribution model proposed for droplet size distributions. The analysis combines Kohler theory with turbulent droplet transport to explain the formation of three modes and their respective flux directions during fog events.

Summary: This study proposes an active-bacterial anti-adhesion strategy based on the directional transportation of bacterial droplets on a star-shaped intelligent response platform (SIRP) for droplet self-actuation. The SIRP demonstrates superior bacterial anti-adhesion during bacterial droplet self-actuation and a very smart infrared-sensing sterilization or micro-reaction response to different types of droplets.

Summary: The development of technologies such as big data analytics, cloud services, IoT, personal mobile devices, social networks, and AI has created a strong demand for enterprises to accumulate information. The amount of recorded data is increasing by about 30-40% per year. Magnetic tape, hard disk drives, and solid-state drives are used for data storage. Hard disk drives are projected to control over half of the world's data due to their low cost per TB. This paper discusses new technologies to meet the growing density demands and competitive solid-state drives for data storage.
