Summary: The traditional methods for preparing Janus membranes are either too complex or lack precise control over surface wettability, layer thickness, and pore structure. This study successfully regulated asymmetric wettability and layer thickness on copper mesh using an interface-confined surface engineering strategy, enabling efficient liquid manipulation. The Janus copper mesh demonstrated superior performance in oil/water separation and fog collection, showing potential for applications in various fields.

Summary: Fog water collection can serve as an alternative source of water supply in areas with limited water resources, but the amount collected is affected by season and meteorological conditions. The orientation of collectors and the frequency of foggy days in the area are among the main factors influencing the differences in yield between collectors.

Summary: The exploration of functional materials for water treatment is a global requirement for protecting life and the environment. However, the current materials used in oil/water separation and water harvesting face challenges such as complicated processing steps, poor microstructure controllability, and small-scale preparation. In this study, a novel WEDM strategy was introduced to fabricate a functional copper mesh with excellent superhydrophobicity, high durability, and efficient fog collection. The multifunctional superhydrophobic mesh shows promise in alleviating water pollution and shortage.

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 study uses various data sources to constrain the changes in global mean total precipitable water and finds that most global climate models exaggerate the predicted increase in atmospheric humidity. The study also finds that global warming will lead to a substantial intensification of the global water cycle.

Summary: Atmospheric water harvesting is a promising solution to the clean water shortage, with two main methods of water collection: capturing water from fog and condensing vapor on surfaces. The research shows that superhydrophobic surfaces play a crucial role in fog collection efficiency, while dew harvesting efficiency depends on a combination of drop mobility and nucleation rate.

Summary: This article introduces a facile and easy-to-operate strategy for surface modification on a stainless-steel mesh based on polymer-assisted laser sintering, which is used for water collection from fog. By sintering a suitable polymer film onto the mesh, different wettability can be obtained. The experimental results show that the rationally designed patterned stainless-steel mesh exhibits excellent performance in fog water collection.

Summary: Freshwater crisis is a global problem, and finding freshwater resources is the key to solving this problem. Solar water purification and fog collection are two separate methods for obtaining fresh water, but they cannot operate 24/7 when used alone. This study reports a hydrogel membrane that can achieve both solar water purification and fog collection, enabling all-day freshwater collection.

Summary: This study investigated the effect of post-harvest storage conditions on the growth kinetics of Salmonella in fresh-cut papaya, finding that the highest growth rate of Salmonella was observed at 21 degrees Celsius and 90% relative humidity. Therefore, better control over storage temperature and relative humidity is crucial in mitigating the risk of Salmonella in papaya.

Summary: A study was conducted on fog-water collection potential at the Mediterranean Iberian Peninsula from 2003 to 2012. The area has a high population density and experiences water restrictions during certain periods of the year. Climate change projections indicate a decrease in precipitation, worsening water problems. The study examined fog-water collection behavior, including during different seasons, on dry days, and the impact of site elevation.
