Summary: One-part geopolymer is a simplified and cost-effective geopolymer material that can be used for eco-friendly building materials. This study optimized its thermal and mechanical properties for geothermal energy applications by incorporating SiC sand and SiC powder. The results showed that the compressive strength can reach up to 83 MPa under ambient curing condition, and the thermal conductivity can be significantly increased with the application of SiC materials. These findings suggest that geopolymer composites with SiC materials are suitable for geothermal energy applications.

Summary: This study aims to develop geopolymer-based composites for geothermal energy applications. The addition of silicon carbide (SiC) powder was found to improve the compressive and flexural strength of geopolymer composites, while the influence of SiC particles was insignificant. The combined application of SiC powder and SiC particle increased the thermal conductivity of geopolymer composites, making it a suitable material for geothermal energy applications. The addition of silicon carbide was also concluded to improve the heat exchange rate and heat utilization efficiency of energy piles.

Summary: In this study, it was found that silicon carbide (SiC) and aluminum nitride (AlN) ceramics suffered serious damage under the long-term irradiation environment of fusion reactors. After ion irradiation, AlN exhibited a higher volumetric swelling (0.45%) than SiC (0.13%). Additionally, the study revealed slight variations in the mechanical properties and thermal conductivity of irradiated SiC, both of which were lower than those of irradiated AlN. This research provides valuable insights for the selection of tritium resistant and functional materials in nuclear fusion reactors.

Summary: Polymer nanocomposites, combining the advantages of polymers and fillers, find wide applications in automobile and aviation industries. Polyimine (PI), an emerging thermoset material, possesses remarkable properties such as malleability, recyclability, and self-healing. To enhance the properties of polyimine matrix, silicon carbide nano-whiskers (SiCw), a cheap and high-hardness filler material, were added. The resulting PI-SiCw nanocomposites showed significantly improved mechanical properties, such as increased bending strength and elongation at break. The addition of SiCw also enhanced the thermal stability of the PI matrix. This cost-effective research provides a promising approach to enhance the mechanical properties of polyimine composites.

Summary: In this study, core-shell structured polydopamine functionalized silicon carbide whiskers were successfully synthesized to improve the dielectric properties of the composites. The presence of PDA effectively suppressed the dielectric loss, and the thicker PDA layer contributed to enhancing dielectric breakdown strength and reducing AC conductivity. This simple coated PDA shell strategy could be extended to develop high performance dielectric polymer composites with other inorganic fillers.

Summary: The paper presents the analysis results of regeneration possibilities for a damaged slider repaired by additive manufacturing technology. The study demonstrates the high quality of the connection zone between the original part and the regenerated zone. Hardness measurements reveal a significant increase, 35%, in the interface between the two materials when using M300 maraging steel for regeneration. Furthermore, digital image correlation technology is utilized to identify the area with the largest deformation during the tensile test, which is outside the connection zone between the two materials.

Summary: This study introduces a cement-glass composite brick (CGCB) with a printed PET-G internal scaffolding, providing an alternative to traditional masonry materials. Made from 86% waste (78% glass waste and 8% recycled PET-G), it offers a cheaper option in the construction market. Tests demonstrated improved thermal properties with the use of the internal grate, including increased thermal conductivity (5%), decreased thermal diffusivity (8%), and decreased specific heat (10%). The CGCB showed lower anisotropy in mechanical properties compared to non-scaffolded parts, indicating the positive effect of using this type of scaffolding in CGCB bricks.

Summary: This study aimed to investigate the morphology, swelling, degradation rate, and biological properties of collagen-based scaffolds modified with caffeic acid, ferulic acid, and gallic acid. The results showed that scaffolds with phenolic acid had higher swelling rate and enzymatic stability compared to pure collagen scaffolds, and exhibited radical scavenging activity in the range of 85-91%. All scaffolds were non-hemolytic and compatible with surrounding tissues. However, collagen modified with ferulic acid had potentially negative effects on hFOB cells, as evidenced by significantly increased LDH release. Nevertheless, all tested materials showed antimicrobial activity against Staphylococcus aureus and Escherichia coli.

Summary: The building industry contributes greatly to climate change through the emission of large amounts of greenhouse gases. A cement composite brick with partial cement substitutes and waste material was developed through research. The physical, mechanical, and thermal properties of the fresh formula mixture and hardened concrete were tested to verify assumptions. The study investigated the role of different proportions of zeolite, metakaolinite, and micrometakaolinite, as well as recycled fibers (glass, polypropylene, and steel), in the production of cement composites. The compressive strength of the modified formula brick increased by 22% compared to the reference sample, and higher values were obtained for splitting and flexural strength. Incorporating fibers into the mixture changed the thermal properties of the concrete, and the composite matrix showed an even distribution of fibers without cracks. The new composite brick has the potential to replace traditional concrete masonry in civil engineering projects.
