Summary: The elastic properties of high- and low-pressure glasses of dipropylene glycol have been investigated in this study, revealing a strong dependence on their thermobaric history. Glasses obtained at high pressure exhibit not only higher densities but also significantly higher elastic moduli, especially in shear modulus. The behavior of elastic moduli during the glass-to-liquid transition also depends on the thermobaric history.

Summary: This study investigates the physical-thermal properties of nanofluids made from graphene powder, propylene glycol, and water. Different ratios of propylene glycol and water were mixed to form nanofluids, and graphene was added at different concentrations. The study examines the viscosity, density, thermal conductivity, and specific heat of the nanofluids. The results show that the addition of graphene nanopowder increases the density and thermal conductivity of the nanofluids, while viscosity and specific heat decrease with increasing temperature.

Summary: In this study, calcium carbonate was encapsulated into Solid-in-Oil-in-Water emulsions to fabricate delivery systems. The concentration of propylene glycol alginate and xanthan gum complexes was found to have a significant impact on the physical stability and structural characteristics of the emulsion microspheres. The S/O/W calcium-lipid emulsion with a concentration of 0.8 wt% PGA-XG complexes exhibited higher physical stability, smaller mean particle size, and higher negative zeta-potential. Confocal laser scanning microscopy and transmission electron microscopy confirmed the encapsulation of calcium carbonate in the emulsion. This study provided new insights for the development of novel calcium preparations with higher quality utilization.

Summary: Nickel-based superalloys are important advanced engineering materials used in high-temperature and corrosive environments. Adding carbide reinforcement improves their mechanical properties, but also affects their thermal properties and corrosion resistance. This research evaluated the thermal properties and oxidation resistance of Inconel 625-(Ti,Zr)C0.85 composites. The experiments revealed that increasing the amount of carbide reinforcement decreased the thermal diffusivity and conductivity of the samples. Suitable chemical reactions were predicted to describe the oxidation process of the composites.

Summary: The influence of different synthesis methods on Cu-Mn-O spinel was evaluated, with the EDTA gel processes method found to be more suitable for spinel synthesis, producing spinels with desirable electrical conductivity and high content. The properties of spinels obtained via solid-state reactions were found to be inferior. The addition of Ni dopant improved electrical conductivity, while Fe showed the opposite effect. Spinels obtained via EDTA gel processes were shown to be promising as protective-conducting coating materials for SOEC/SOFCs steel interconnects.

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: Ice crystal icing is a significant hazard in aviation, and accurate modeling of sticking efficiency is essential. In this study, icing wind tunnel experiments were conducted to quantify the volumetric liquid water fraction, sticking efficiency, and maximum thickness of ice layers. Two measurement techniques, calorimetry and capacitive measurements, were used to measure the liquid water content and distribution in the ice layers. The experiments showed that increasing wet bulb temperatures and substrate heat flux significantly increased sticking efficiency and maximum ice layer thickness.

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.
