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: The lack of water is a critical issue for peasant communities in the Andean highlands, such as Galte-Yaguachi community in Ecuador. To address this, a fog collector system was built using Urku Yaku material to provide water for the community. The collected water met quality standards for human consumption. With the successful implementation, this system can be expanded to benefit other communities with similar needs.

Summary: The electrostatic droplet collection technology has great potential in harvesting water from fog. However, the impact of droplet evaporation on the collection efficiency is not clear, which hinders its industrial application. In this study, a lab-scale electrostatic fog plume collector was developed and a numerical model was used to account for droplet evaporation. Results showed that the fluid transport process in the electrostatic device can be accurately predicted. The droplet collection efficiency decreases exponentially with increasing water vapor mass fraction difference and is influenced by factors such as droplet mass concentration and fog plume velocity.

Summary: Photovoltaic panels convert solar energy into electricity by using semiconductor materials and absorbing heat from solar radiation, but the efficiency of electricity generation is affected by the panel's temperature. Thus, cooling photovoltaic panels has become a focus of research, with cost reduction and energy consumption being important considerations. This study used two models of open-flow flat collectors to analyze the performance of PV panels and improve the cooling process. The results showed that the collector design had an impact on the PV/T system performance and panel temperature, with an increase in panel performance observed with both models.

Summary: Reliable precipitation information is crucial for scientific and operational applications. Open-access gridded precipitation products (OGPPs) are important sources due to their continuous spatiotemporal coverage. This study proposes a methodology to comprehensively compare the accuracies and stabilities of ten different OGPPs, particularly in mountainous basins. The results show high accuracy but unstable performance of all OGPPs, with multi-source fusion-type products offering better stability and accuracy. Multi-source weighted-ensemble precipitation and climate prediction center morphing method products exhibit the best comprehensive performance.

Summary: This study, based on reanalysis data from 1980 to 2019, reveals that the relationship between autumn sea ice concentration in the Barents-Kara Seas (BKSIC) and subsequent winter North Atlantic Oscillation (NAO) underwent an interdecadal weakening in the early 1990s. The weakening can be attributed to the decrease in the interannual variability of BKSIC, which leads to a discrepancy in the tropospheric warming. In the former period (1980-1993), the decrease in autumn BKSIC enhances tropospheric warming and weakens the circumpolar westerly, resulting in a negative NAO phase. However, in the latter period (1994-2019), the smaller interannual variability of BKSIC weakens its influence on the tropospheric temperature, diluting the relationship with the subsequent winter NAO.

Summary: Significant phase shifts in winter surface air temperature (SAT) anomalies have occurred in East Asia in recent years, leading to detrimental effects on socio-economic activities. In this study, the fourth principal mode of month-to-month SAT variations over EA in winter was identified, representing subseasonal SAT reversals over the mid-high latitudes of EA during late winter. The formation of this mode is accompanied by stratospheric temperature anomalies over eastern Siberia-Alaska in January.
