Summary: Inspired by the water film-trapping characteristics of Tillandsia, we propose a fog collection method utilizing calcium alginate hydrogel-coated wires. Our hydrogel-coated wire outperforms a bare wire in fog collection efficiency (up to 136% higher) under different flow speed conditions by maintaining the effective wire diameter through water film trapped on the hydrogel. Additionally, the hydrogel-coated dual-wires have a collection efficiency 1.2 to 1.7 times higher than that of two bare dual-wires by preventing the formation of water bridges between wires.

Summary: Despite scientific advances, access to fresh water remains a major challenge due to water shortage and contamination. Various attempts have been made to harvest water from the atmosphere, with condensation systems being of particular interest. However, the high energy consumption and need for water treatment increase costs. Sorption systems, such as Metal-Organic Frameworks (MOFs), offer promising solutions for atmospheric water harvesting at low humidity, using only solar energy and producing drinkable water. This review examines different harvesting systems and methods, and discusses the adsorption and desorption mechanisms in sorption systems.

Summary: Water scarcity due to population growth and pollution poses a threat to human survival, but harvesting atmospheric water from fog and vapor can help resolve the emerging water crisis. In this review, we examine the progress of atmospheric water harvesting (AWH) technologies and discuss how interfacial interactions among solid, liquid, and air determine AWH performance. We also highlight practical applications of AWH and emphasize the challenges in the surface design of future AWH devices.

Summary: In this study, a convenient and cost-effective method for fabricating a bio-inspired hybrid super-wettable surface (HSWS) using imprinted MoS2 was presented. By imprinting MoS2 nanoflowers with amino acid and octadecane, hydrophilic and hydrophobic properties were endowed. The water collection efficiency factor (eta) of the HSWS based on heterogeneous MoS2 compositions and blending ratio outperformed that of the homogeneous MoS2. The optimal proportion (6:4) of hydrophobic and hydrophilic MoS2 achieved an eta of 20%, which was double that of the pure MoS2 sample, demonstrating the synergy effect during fog harvesting.

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: In regions with limited drinking water resources like the Middle East, a device has been developed to harvest clean drinking water from air using adsorption materials. Experimental studies have shown that the device can produce a significant amount of water under specific conditions, and increasing the relative humidity can improve water capture rates and overall efficiency. Further improvements can be made by incorporating multiple layers of sorbent and using sorbents with enhanced adsorption and desorption properties.

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.
