Summary: Soft fruits like strawberries are prone to postharvest decay due to fungal infestation, which can be exacerbated by elevated temperatures and condensation in packaging. Optimal packaging, such as top sealed paperboard, is essential for homogenous fruit cooling and ventilation. Through laboratory experiments, simulations, and physics-based models, the study found that top sealed paperboard packaging performed best in terms of respiration-dependent quality, mass loss, and time of wetness, with minimal heterogeneities in fruit quality attributes. Experimenting in combination with mechanistic modeling provides a deeper understanding of fruit evolution in a supply chain.

Summary: This study investigates the effects of calcium (Ca) on water soaking in strawberries. The results show that CaCl2 can decrease water soaking and anthocyanin leakage, but has no effect on water uptake. Different calcium salts and chloride ions have varying effects on water soaking, with only CaCl2 significantly reducing water soaking. CaCl2 is found to decrease microcracking of the strawberry cuticle and reduce leakage of plasma membranes, thus decreasing water soaking.

Summary: In this study, four extraction methods, ultrasound (U), microwave (M), simultaneous ultrasound-microwave (UM), and heat treatment (HT), were evaluated for their use in developing functional foods. The results showed that UM method had a similar yield (72%) to the other methods but with a shorter extraction time (5 min). In addition, FTIR spectra analysis revealed the presence of regions corresponding to fatty acids and carbohydrates. Therefore, using UM to obtain agavins is a more environmentally friendly and fast process.

Summary: This study investigates the drying properties of potato peels (PP) using two different processes: convection drying (CD) and microwave drying (MD). The drying kinetics were analyzed at various temperatures for CD and different powers for MD. The study also evaluated the effectiveness of these processes in terms of antioxidant contents and capacity. A total of 22 mathematical models were used to predict the drying kinetics, and the Sledz model was found to be the most suitable. The best drying rates for PP were achieved at a temperature of 120 degrees C and a power of 600 W. The energy consumption increased with higher temperature or power. MD showed shorter drying time, lower energy consumption, and better preservation of antioxidants compared to CD. The proposed microwave drying process for PP is recommended for various industries, including food processing.

Summary: The study demonstrated that microwave-assisted convective drying of white mushrooms resulted in shorter drying time, increased drying rate, and higher moisture diffusivity, making it more energy efficient. The Page and Weibull models were found to be the most valid for approximating experimental drying curves. Although mushrooms dried using hybrid methods experienced discoloration and shrinkage, those dried with 200 W microwave power at 30 degrees C had the highest polyphenol content, and both drying techniques produced microbiologically stable dry products with water activity below 0.5.

Summary: This study investigates the natural convection effects in the insulation layers of spherical storage tanks and their impact on the tanks' performance. The permeability and Rayleigh number of the insulation material are considered as key factors. The results show that as the Rayleigh number increases, new convective cells emerge and cause the cold boundary to approach the external hot boundary. In the case of large temperature differences, multiple solutions may coexist.

Summary: This paper investigates the two-phase flow and heat transfer characteristics of low-velocity jet impacting on a cylindrical surface. The study reveals that the heat transfer regimes are non-phase transition and nucleate boiling with the increase of heat transfer rate. The effects of jet impact height and outlet velocity on local surface temperatures are pronounced at the non-phase transition stage. The growth rates of heat transfer rate and liquid loss rate increase significantly from the non-phase transition to nucleate boiling stage.

Summary: This study investigates the condensation, frosting, and defrosting processes on superhydrophobic surfaces with millimeter-scale structures. The results reveal that the structures can influence the growth and removal of frost crystals, with the bottom grooves creating a frost-free zone and conical edges promoting higher frost crystal heights. Two effective methods for defrosting are observed: hand-lifting the groove and airfoil retraction contraction on protruding structures. This research provides valuable insights into frost formation and defrosting on millimeter-structured superhydrophobic surfaces, with potential applications in anti-frost engineering.

Summary: This study developed two thermal concentrators, one with a 2D design of uniform thickness and another with a 3D design, using the coordinate transformation technique and metamaterials. By structuring the thermal conductor, the desired local density-heat capacity product and anisotropic thermal conductivities were achieved. The homogenized thermal conductivities were obtained from finite element simulations and cylindrical symmetry consideration. A 3D concentrator was fabricated using 3D metal printing and characterized using a thermal camera. Compared to devices that solely consider anisotropic conductivities, the time evolution characteristics of the metadevice designed with coordinate transformation were closer to those of an ideal concentrator.

Summary: In this study, we investigated the supercritical heat transfer of CO2 in a horizontal tube with a diameter of 10.0 mm, covering a wide range of pressures, mass fluxes, and heat fluxes. The study revealed a non-monotonic increase in wall temperatures along the flow direction and observed both positive and negative wall temperature differences between the bottom and top tube. The findings were explained by the thermal conduction in the solid wall interacting with the stratified-wavy flow in the tube.
