Summary: The study focuses on the rheological, mechanical, and microstructural properties of HNT reinforced cementitious composites under varying ultrasonication energies. It was found that higher ultrasonication energy reduced porosity, leading to improved compressive and flexural strength, but decreased workability of fresh HNT cement mortars. The research highlights the importance of finding the optimal ultrasonication energy independent of HNT concentration for enhancing the engineering properties of the composites.

Summary: Egypt is the largest producer of rice straw, but the disposal of this waste in landfills and open fields has caused environmental damage. Moreover, eggshells used in bakeries, restaurants, and poultry farms are usually discarded in landfills, posing health hazards. However, grinding eggshells into nanoparticles, known as nano eggshell powder (NEP), can increase its activity. This study examined the characteristics of ultra-high-performance concrete (UHPC) produced using eco-friendly components, rice straw ash (RSA) and NEP, as partial cement substitutes. The results showed that using RSA and NEP as pozzolanic materials improved concrete characteristics, reduced cement content, and reduced environmental contamination.

Summary: A Zn-2Cu-0.1Ti (ZCT) alloy was fabricated using a combination of casting and hot-rolling. X-ray diffraction analysis revealed the presence of TiZn16 and CuZn4 phases in the alloy. The ZCT alloy exhibited a significantly higher yield strength compared to pure zinc, as well as similar elongation to failure. Additionally, the alloy had a lower corrosion rate in simulated body fluid and showed excellent biocompatibility for MC3T3-E1 cells, indicating its potential for clinical applications.

Summary: The role of polyethylene glycol (PEG) on the crystal structure, morphology, and electrochemical behavior of V2O5 nanoparticles was investigated in this study. PEG was found to be an effective modifier for the synthesis of V2O5 nanofibers, acting as a structure directing agent and a precursor for forming a carbon matrix. The V2O5-PEG/FSSM exhibited a specific capacitance of 520.3 F g(-1) and excellent cyclic stability, outperforming the bare V2O5. The assembled V2O5-PEG/FSSM-based symmetric capacitor device delivered a specific capacitance of 81.7 F g(-1) with an energy density of 16.3Wh kg(-1), attributed to the intercalated PEG molecules providing a high specific surface area and interconnected nanofiber network-like morphology.

Summary: This study investigates the use of binders and solvents in MXene electrode fabrication and their impact on supercapacitive performance. MXene electrodes were screen printed on a flexible stainless steel mesh substrate using a straightforward and cost-effective approach. The influence of binders and solvents on electrochemical performance was examined by comparing electrodes with and without a binder. The use of a binder resulted in altered electrochemical performance, with the MX-E@FSSM electrode showing the best performance. Furthermore, an MnO2/MXene//MX-E asymmetric supercapacitor demonstrated promising performance with a specific capacitance of 252 F g(-1) at an energy density of 35.2 Wh kg(-1).

Summary: This paper discusses the directed energy deposition of 15-5 PH with tailored precipitation hardening to achieve desired properties. Parametric analysis of solution annealing and aging was performed, and material characterisation included microscopy, SEM/EDS, hardness, tensile, and impact toughness test. The optimised solution annealing allowed for homogeneous austenite and subsequent precipitation hardening resulted in similar properties to conventionally produced steel, with peak aging exhibiting high hardness and tensile strength, and over-aging condition showing good impact toughness.

Summary: Sandwich composites consisting of regenerated cellulose fabric and bio-based polypropylene as facings, as well as virgin and recycled polyamide textiles as core materials, were produced using compression moulding techniques. The addition of thicker recycled textile improved the bending stiffness and peak flexural force. Substituting one layer of recycled textile for two layers of virgin material provided good impact energy absorption capacity and maximum force. Tensile strength varied among the different composite materials, but no evidence of fiber tow debonding, fiber bundle splitting, or delamination was observed.

Summary: Studies on the effects of environmental conditions on natural fibres and their composites have gained significant attention. The hydrophilic nature of natural fibres makes them prone to water absorption, which negatively impacts the mechanical properties of natural-fibre-reinforced composites (NFRCs). NFRCs, used in lightweight materials for automobile and aerospace components, need to withstand extreme temperatures and humid conditions worldwide. This paper critically discusses the impact performance of NFRCs under environmental conditions, focusing on moisture ingress and relative humidity as damage mechanisms.

Summary: This study investigates the damping and viscoelastic properties of flax/epoxy composites and their carbon fiber hybrid laminates. The results show that the location and number of flax plies contribute to the damping behavior, while the bending stiffness is mainly influenced by the position of carbon plies. The damping ratio varies for each vibration mode, and the trade-off between flexural stiffness and damping ratio can lead to significant improvements in specific configurations.
