Summary: This study evaluated six commonly used models for estimating evaporation from snow surfaces (ESS) at twelve high-latitude and high-altitude CO2 flux observation sites. The Penman model showed the best performance on both the hourly and daily scales, with KGE coefficients of 0.75 and 0.65, respectively. In the absence of net radiation data, the empirical model is recommended.

Summary: Selecting the temperature of each vessel in a multi-effect evaporator process can be a trial-and-error procedure due to the specified heat-transfer areas. However, a method presented in this paper allows for direct calculation of stage temperatures for any number of stages in the series, eliminating the need for trial-and-error.

Summary: The development of strong-scaling computational tools for high-throughput methods with open-source code has transformed computational materials science communities, but there are still gaps in supporting experimental techniques such as Atom Probe Tomography (APT). Data science tools are necessary for extracting chemo-structural spatial correlations, as post-processing for high-end analysis techniques like APT still relies on proprietary software with limited performance and transparency.

Summary: This study develops a mathematical model of a rectangular microchannel heat sink (MCHS) and derives the thermal resistance using structural parameters based on the differential equation of energy conservation. Both experimental and numerical methods are employed to validate the model. A multiobjective optimization model is also established to simultaneously minimize the thermal resistance and the pumping power. The mathematical model and the multiobjective optimization method are beneficial for the design of an MCHS owing to the high convenience and reliability.

Summary: A new model for heating and evaporation of a droplet on a superhydrophobic surface is proposed, using the analytical solution to the heat transfer equation. The assumptions that heat supplied by conduction and radiation is distributed throughout the droplet volume and that the effects of ambient gas temperature gradient can be ignored, are discussed. The model is validated using experimental data, showing good agreement with the results when the assumptions are satisfied.

Summary: Analytical studies and numerical simulations have shown that increasing core radius in multi-mode fibers reduces the impact of nonlinear effects by enlarging effective mode field areas. However, the presence of more propagating modes also strengthens the impact of nonlinear signal degradations on data transmission. Despite this, the two trends are mostly balanced, allowing for comparable system performance to standard single-mode fibers for at least 100 modes.

Summary: A novel method is proposed to estimate optimal parameters and active power of a single-diode PV module model, utilizing a multi-parameter model that adapts to environmental changes and an online optimization scheme. The adaptive Levenberg-Marquardt method is used to overcome traditional LM method issues, while global sensitivity analysis helps identify critical parameters for improved accuracy. Testing on real-world PV systems in diverse conditions shows the proposed method yields more accurate parameters and closer to true PV generation outputs compared to conventional methods.

Summary: This paper proposes a robust method for multi-response optimization that considers the location effect, dispersion effect, and model uncertainty simultaneously. A multi-objective optimization model is proposed to maximize the satisfaction degrees of the local and dispersion effects, using a robust desirability function. The proposed model yields a set of non-dominated solutions that approximate the Pareto front, providing flexibility for decision makers. Experimental results show that the proposed method produces robust solutions and outperforms other multi-objective optimization algorithms in terms of search performance.

Summary: The influence of patterned combinations of wettability on evaporation heat transfer was investigated using molecular dynamics simulation. The microscopic mechanisms affecting heat transfer were analyzed by examining the liquid-vapor and solid-liquid interfaces. It was found that the solid-liquid interface had a significant impact on heat transfer, while the patterned combinations had no effect on liquid-vapor interface heat transfer. The heat transfer rate was positively correlated with the length of the contact boundary line between hydrophilic and hydrophobic parts, suggesting that optimizing surface construction through extending the contact boundary line can improve heat transfer performance.

Summary: This study investigated the effects of nanoencapsulation and gel incorporation on the antioxidant activity, stability, and release profile of curcumin. The results showed that CUR-loaded nanoparticles and CUR NPs-filled gelatin-genipin gels had significantly higher antioxidant activity, stability, and in vitro release profile compared to free CUR. The GL/GP-CUR NPs exhibited the highest antioxidant activity and increased stability, while the CUR NPs had a faster release rate. These findings suggest that GL/GP-CUR NPs have potential as an effective delivery system for CUR in the food industry.

Summary: This study developed solid microcapsules containing co-loaded vitamin B12 and D3 using a W1/O/W2 emulsions and spray-drying method. The addition of polysaccharides as co-encapsulants improved the morphological characteristics, encapsulation efficiency, storage stability, and gastrointestinal simulation of the microcapsules. The electrostatic bonding with chitosan and multilayer protection from the W1/O/W2 structure contributed to the high encapsulation efficiency of vitB12. Incorporating polysaccharides into W2 enhanced the particle integrity of the dried powders and improved the retention rate and encapsulation efficiency of vitamins. Sodium carboxymethylcellulose showed the best protection for vitB12 and lower degradation rates for vitD3, while sodium alginate exhibited controlled release and the highest cumulative release under simulated gastric and intestinal conditions, respectively.

Summary: This study investigates the effects of swelling on espresso extraction by incorporating a particle-level swelling model into a one-dimensional bed-level extraction model. The results show that swelling only slightly affects the yield and strength at a fixed flow rate, but considerably enhances the strength at a fixed pressure drop. The finer the coffee particles, the more pronounced the enhancement. It is suggested that better control of yield and strength can be achieved by fixing the flow rate in an espresso machine. It is also indicated that numerical extraction simulations, when properly incorporated with relevant physical effects, can be used to predict the extraction kinetics and guide the design and production of espresso machines.

Summary: Methyltetrahydrophthalic anhydride (MeTHPA) esterified corn starches (MeCS) with degrees of substitution (DS) ranging from 0.0066 to 0.072 were prepared and found to be effective in stabilizing Pickering emulsion. The modification of MeTHPA damaged the crystal structure of corn starch, roughened its surface structure, and increased its contact angle, which were positively correlated with the DS of MeCS. The particle size of MeCS increased and then decreased with increasing DS, with the smallest size observed for MeCS with a DS of 0.072. The Pickering emulsions stabilized by MeCS with a DS of 0.072 exhibited better stability compared to those stabilized by MeCS with lower DS, which can be attributed to their smaller particle size and higher viscosity. MeCS with a DS of 0.072, at a concentration of 3% (w/v), could maintain emulsion stability even after 50 days of storage. These findings suggest that MeCS with appropriate DS and concentration levels could be effective particle stabilizers for Pickering emulsions.
