Atmospheric water harvesting (AWH) technology is an emerging sustainable development strategy to deal with global water scarcity. To better understand the current state of AWH technology development, we conducted a bibliometric analysis highlighting three water harvesting technologies (fog harvesting, condensation, and sorption). By comprehensively reviewing the research progress and performing a comparative assessment of these technologies, we summarized past achievements and critically analyzed the different technologies. Traditional fog collectors are more mature, but their efficiency still needs to be improved. External field-driven fog harvesting and active condensation need to be driven by external forces, and passive condensation has high requirements for environmental humidity. Emerging bio-inspired fog harvesting and sorption technology provide new possibilities for atmospheric water collection, but they have high requirements for materials, and their commercial application is still to be further promoted. Based on the key characteristics of each technology, we presented the development prospects for the joint use of integrated/hybrid systems. Next, the water-energy relationship is used as a link to clarify the future development strategy of AWH technology in energy driving and conversion. Finally, we outlined the core ideas of AWH for both basic research and practical applications and described its limitless possibilities for drinking water supply and agricultural irrigation. This review provides an essential reference for the development and practical application of AWH technologies, which contribute to the sustainable utilization of water resources globally.

Our study addresses the pressing global freshwater scarcity crisis by engineering advanced liquid-entrapped nanosurfaces optimized for highly efficient atmospheric water harvesting (AWH). Through a synergistic approach integrating carbon fiber paper (CFP), hydrothermally synthesized nanoneedles (NNs), and silicone oil liquid entrapment (LE) within NNs, we achieved remarkable improvements in water collection efficiency. While CFP captures fog effectively during AWH, it faces challenges with water-pinning effects, mitigated by NNs' improved droplet-spreading properties, leading to a notable 50% increase in harvesting efficiency.

Background: The National Emergency Laparotomy Audit (NELA) risk prediction tool has demonstrated superiority in predicting 30-day mortality after emergency laparotomy (EL). The aim of our study was to evaluate the accuracy of NELA in calculating long-term (5 year) mortality and determine factors predicting long-term risk of death after EL.
Methods: This retrospective cohort study included consecutive patients who underwent EL for any indication other than trauma between May 2012 and June 2017 at a large tertiary and academic teaching center.
