Summary: The research successfully developed lightweight cement-based boards by adding different percentages of SAP, which decreased the density of the cement boards. However, increasing the percentage of SAP resulted in higher apparent porosity of cement boards, affecting the microstructure and mechanical performance significantly.

Summary: This study investigates the structure-property relationship of blending different grades of repeatedly melt-extruded HDPE with virgin HDPE. The results show that blending these different grades of HDPE with virgin HDPE does not significantly affect the melt rheology, tensile properties, and overall migration compared to virgin HDPE, supporting the feasibility of achieving the target set by the UK Dairy Roadmap.

Summary: The recyclability of opaque PET containing TiO2 nanoparticles has not been well-studied compared to transparent PET. This study found that adding Joncryl during reactive extrusion can increase molecular weight, but this increase in chain length does not explain the decrease in crystallization rate. Furthermore, the reactive extruded REX-r-PET showed important structural modifications and enhanced rheological and mechanical properties due to the production of chain extension and long-chain branches.

Summary: In this study, a high-performance Mg-8Gd-2Y-1Zn-6Li alloy was successfully fabricated, showing significant improvements in yield strength and ultimate tensile strength. The investigation of intermetallic compounds revealed the unique microstructure features and the discovery of a novel island-like beta(1R) phase in Mg-Gd-Li based alloys. These structural components contribute to the high performance of the alloy.

Summary: In this study, a Mg alloy with alloying elements of Zn, Al, Sn, and Mn was designed, and hot extrusion was carried out at various speeds and temperatures. It was found that high speed extrusion resulted in more second phase particles, while high extrusion temperature increased the number of second phases, grain size, and dynamic recrystallization degree. The sample extruded at a speed of 10 mm/min and temperature of 300 degrees C showed the highest yield strength, tensile strength, and corrosion resistance.

Summary: This study investigates the influence of alloying elements in Al-Cu-Li alloys rods produced by novel powder metallurgy routes. Two different methods were used to prepare 5mm diameter rods, and they were characterized by SEM, EBSD, Vickers microhardness, chemical composition (ICP-OES), and tensile tests. The results show that alloy 1 (AA2060) has a more homogeneous microstructure than alloy 2 (AA2196), and the addition of Mg improves the microstructure after heat treatment.

Summary: This study investigated the effects of Ga content on the microstructure and mechanical properties of hot-extruded Mg-2Zn-xGa alloys. The results showed that increasing Ga content refined the grains and increased the amount of Mg5Ga2 precipitates, leading to enhanced strength properties. However, excessive Mg5Ga2 precipitates resulted in reduced elongation.

Summary: Magnesium alloys are potential materials for temporary fixation devices in osteosynthesis due to their similar density and Young's modulus to cortical bone. In this study, Mg-Zn-Ga-(Y) alloys were prepared by hot extrusion and their microstructure and mechanical properties were investigated. The results showed that the Mg-Zn-Ga-(Y) alloys exhibited favorable mechanical properties and bone regeneration ability.

Summary: The addition of Al and Ca microelements can improve the mechanical properties of magnesium alloys, but Al addition can deteriorate corrosion resistance, while the single addition of Ca can help increase both tensile and compressive yield strengths and improve yield anisotropy. This property improvement was achieved without compromising corrosion resistance. A ViscoPlastic Self-Consistent simulation showed that the single Ca addition effectively enhanced the hardening of basal and prismatic slips, resulting in improved yield strength in both tension and compression.

Summary: This study investigates the effects of Sn addition on the microstructural characteristics and mechanical properties of an extruded Mg-Bi binary alloy. The results show that the addition of Sn significantly decreases the average grain size and improves the tensile strength and ductility of the alloy. These improvements are attributed to grain refinement, Sn solute atoms, and increased dislocation density.

Summary: The study fabricated Pt nanoparticles on PBI/MWCNT support with fine ECSA for hydrogen oxidation, showing higher durability compared to Pt/MWCNT and commercial Pt/C. Despite this, performance tests in HT-PEMFC demonstrated that there is a trade-off between durability and power density values, with Pt/C outperforming Pt-PBI/MWCNT at all temperatures.

Summary: Bulgur bran, a byproduct of bulgur production, can be utilized for biodegradable food packaging films with improved properties through the incorporation of nanocelluloses and citric acid. Nanocellulose-reinforced films showed enhanced tensile strength and reduced water solubility, while also lowering water vapor permeability. The use of nanocelluloses in films can improve mechanical and barrier properties, making them promising for commercialization.
