Summary: Global reservoir information is crucial for water management and understanding the hydrological cycle, but operational data on reservoir storage and evaporation monitoring is lacking globally. NASA has introduced a new MODIS/VIIRS Global Water Reservoir product suite based on moderate resolution remote sensing data, covering 164 large reservoirs. This product provides valuable information on reservoir area, elevation, storage, evaporation rate, and volume.

Summary: This study estimated monthly reservoir evaporation losses for 916 large reservoirs in China from 1985 to 2018. Total evaporation losses significantly increased due to significant increases in evaporation rate and reservoir surface area. Evaporation losses of large reservoirs in China are significantly smaller than that in the United States, mainly due to the larger average depth and smaller area of China's large reservoirs.

Summary: Enhanced reservoir evaporation is a growing concern due to increasing water demand, and this study evaluated evaporation rates and losses for major reservoirs in the Contiguous United States. Using the Lake Evaporation Model and climate projections, it was found that evaporation loss may increase significantly over the research period. The Rio Grande region is projected to have the highest increasing rate, with the most significant increase occurring during the fall season.

Summary: Reservoir immersion can cause environmental geological problems, and its scope is closely related to changes in groundwater levels. The study finds that the groundwater level exhibits hysteresis relative to the reservoir water level due to the low permeability of the soil. The closer to the reservoir, the faster the groundwater level rises or falls.

Summary: Estimating global reservoir evaporation losses is crucial for reservoir management, but there is still a gap in estimating at a global scale due to data limitations. Using two new datasets, we successfully estimated the evaporation volume of 7242 large reservoirs worldwide from 1985 to 2016. The results show significant and increasing evaporation losses, with 80% of the increment contributed by middle-income countries.

Summary: A new three-dimensional solar absorber composed of magnetic nano particles has been proposed for solar-driven interfacial evaporation system. The absorber can be restructured and recycled by adjusting the magnetic field. Experiments showed that the interfacial evaporation system using this novel absorber achieved high thermal efficiency and evaporation rate, with significant impacts from air speed, light intensity, and relative humidity.

Summary: The study evaluated the performance and cost of a model floating photovoltaic (FPV) plant in an Indian reservoir, exploring different tilt angles, mounting systems, and tracking mechanisms for power generation optimization. The analysis identified a landscape flat-mount system with high performance ratio, while recommending fixed-tilt and single-axis tracking FPV systems for the specific reservoir. Additionally, the study presented cost analysis and carbon-footprint estimation to showcase the economic and environmental benefits of the system, highlighting the higher CO2 savings potential with a tracking FPV system compared to a fixed-mount FPV system.

Summary: Latte, a mixture of coffee and milk, is a complex fluid containing biomolecules that often forms intricate deposit patterns after droplet evaporation. However, the evaporation and deposition dynamics of biofluids are not well understood due to their complexity. In this study, we investigate the dynamics of latte droplet evaporation and deposition, focusing on crack development and inhibition in the deposit patterns. We find that the surfactant-like properties of milk and the intermolecular interactions between coffee particles and milk bioparticles contribute to uniform crackfree deposits. This finding enhances our understanding of pattern formation in evaporating droplets with complex biofluids and offers insights for the applications of bioinks with both printability and biocompatibility.

Summary: In this study, the vacuum refining of high-Mn steel was conducted using a vacuum induction furnace with the addition of slag to investigate the behaviors of Mn evaporation and nitrogen removal. It was found that the addition of slag can effectively reduce the Mn evaporation rate in molten steel. Furthermore, the inhibition effect of the slag layer on Mn evaporation decreases with the increase of the initial Mn content in molten steel.

Summary: The present study experimentally analyzed flash evaporation and found that the initial water temperature and back pressure have significant effects on the evaporation rate and cooling rate. Increasing the initial water temperature enhances both rates, while increasing the back pressure decreases them. Additionally, the visualization procedure revealed the importance of the degree of superheat in flash evaporation.

Summary: We experimentally studied the influence of copper and steel surface texture on the phase transition of water droplets. The results showed that an increase in roughness led to a decrease in wetting of copper and an improvement in wetting of steel. Wetting was found to be the most significant factor affecting the spreading diameter. Additionally, we proposed a hypothesis for the increase in contact angle and the decrease in contact diameter, and found that an increase in surface area resulted in an increase in the total evaporation rate.

Summary: This study investigates the evaporation of gold nanofluid droplets on a heated silicon substrate, analyzing the size effect of gold nanoparticles and the impact of surface coating on heat transfer. The research uses optical, infrared thermography, and acoustic methods to study the evaporation process and reveals that the addition of a surfactant decreases the effectiveness of heat transfer in gold nanofluids.
