Summary: This study addresses the issues of high cost, scarce resources, and poor heat resistance associated with beeswax used in traditional Chinese hot waxed wood technology. By modifying polyethylene wax with a grafted maleic anhydride-methyl methacrylate co-monomer, a low-cost, high-melting-point, stable, and polar alternative to beeswax suitable for hot waxing wood was developed. The effects of grafting conditions on the properties of the modified polyethylene wax were studied, and it was found that the modified wax exhibited similar chemical properties to beeswax but with higher thermal stability and melting temperature.

Summary: Grafting hydrolyzed poly(ethylene-alt-maleic anhydride) onto pulp fibers increases the density of surface charge groups and can regenerate reactive succinic anhydride groups through high-temperature curing. This grafting process does not affect pulp refining characteristics but can significantly improve the wet strength of papers under specific drying conditions. The curing process generates anhydride groups that increase the ester linkages on fiber surfaces, giving the pulps thermosetting properties.

Summary: This study prepared a new form-stable phase change thermal interface material by melt blending paraffin wax (PW) and low-density polyethylene (LDPE), and the thermal conductivity of the material was improved by adding aluminum (Al) powder. The influence of Al powder addition on the internal structure, thermal properties, and phase change behavior of the PW/LDPE matrix was systematically studied. The results confirmed that the addition of Al powder improved the thermal conductivity of the material without a significant impact on other properties, and the thermal conductivity increased with the increase of Al addition. Therefore, morphologically stable PW/LDPE/Al is an important development direction for thermal interface materials.

Summary: This article investigates the influence of molecular interaction and morphology on the thermal and mechanical properties of LLDPE/wax blends. The cooling rate is not sufficient to determine the interactions between the molecules in the blends, therefore, samples were cooled at different rates to model the thermal and mechanical properties. The results show the cocrystallization of wax with LLDPE and confirm the rapid crystallization of both components.

Summary: Spin coating is commonly used to prepare thin films with uniformity and controlled thickness. However, it has not been successful in producing free-standing thin films of polyolefins due to their insufficient strength. In this study, we have achieved free-standing thin films of polyolefins, such as polyethylene, with varying thickness. These films can be used for hydrophobic coating, filtration membranes, and oil-sorbents.

Summary: Mixed polyolefin-based waste requires immediate attention to mitigate its negative impact on the environment. The separation of these plastics is energy-intensive due to their similar densities, and they cannot be blended without compatibilizers due to their inherent incompatibility. This study presents non-wettable microporous sheets made from recycled polyethylene (PE) and polypropylene (PP), which demonstrate efficient oil-water separation and high reusability. These findings emphasize the importance of sustainable solutions for plastic recycling and mitigating oil spill problems.

Summary: Metastable beta Ti alloys based on the Ti-Nb system have attracted attention due to their unique properties. However, the unstable cyclic behavior of these alloys has hindered their widespread industrial use. Recent studies have shown that internal stresses, including those from dislocations, may be responsible for this behavior. This study demonstrates that inter-cycle thermal treatments can mitigate the unstable cyclic behavior, providing a significant breakthrough in our understanding of Ti-Nb superelastic materials.

Summary: This paper systematically investigated the evolution of microstructure in Fe-Ni-Co-Al polycrystalline alloys and its effects on mechanical properties. The results revealed that the migration of grain boundaries in different processes is driven by different factors, which impacts the grain orientation and precipitate formation. In the process of directional recrystallization, grains with specific orientations grow in the grain boundary region and form the dominant orientation, while grains with lower migration rate form the minor orientation. The alloy produced through directional recrystallization exhibited good recoverable strain and superelastic strain, while the alloy produced through solid solution treatment showed no evident superelastic behavior.

Summary: This study employed laser metal deposition to additively manufacture Ti-15Mo wt% alloy, and subsequently subjected it to post-fabrication uniaxial thermomechanical processing. The results showed that different zones in the microstructure remained after processing, and deformation mechanisms mainly involved slip and martensite formation. The compressive mechanical properties were found to be dependent on strain rate, with higher flow stress and compressive strength observed at higher strain rates. Grain structure homogenisation was not achieved, leading to anisotropic tensile properties.

Summary: This study examines the effect of Cr additions on the mechanical behavior of TWIP steel at temperatures ranging from 25°C to 350°C. The results indicate that different temperature-dependent strengthening mechanisms, including mechanical twinning, Dynamic Strain Aging, and slip bands, are at play. The stacking fault energy (SFE) influences the percentage of mechanical twinning, which in turn affects the strain hardening rate.

Summary: The mechanical properties and microstructural evolution of C-doped TRIP-assisted HEA under dynamic loading conditions were systematically investigated in this study. The results showed that dynamic tensile deformation led to an increase in yield strength and a decrease in ultimate tensile strength, with a trend towards increased total elongation. The primary deformation mechanisms shifted from TRIP and TWIP effects to deformation twinning and dislocations. The presence of carbides formed through C-doping hindered dislocation slip and promoted the activation of multiple twinning systems.
