Summary: A facile synthesis of rGO-CuO nanocomposite was successfully achieved using hydrothermal method. The synthesized nanocomposites were characterized using various techniques, such as XRD, FTIR, Raman spectroscopy, SEM, EDX, and TEM. The addition of rGO-CuO to the base AFC significantly improved its performance, including increased combustion efficiency, decreased combustion temperature and MEC, and increased burn rate, leading to faster fire extinguishment. The developed AFC shows promise in meeting the requirement for faster fire suppression in the future.

Summary: In this study, CuO nanoparticles were synthesized by a simple, one-pot mechanochemical approach using the leaf extract of Seriphidium oliverianum as a reducing and stabilizing agent. The CuO NPs showed high potential for degrading water-soluble industrial dyes, with degradation rates of 65.231% +/- 0.242 for methyl green (MG) and 65.078% +/- 0.392 for methyl orange (MO). This bio-mechanochemically synthesized CuO NPs are promising candidates for efficient dye removal from water.

Summary: This study discovered for the first time the significant differences in catalytic properties caused by different 'isotopic catalysts'. The commonly purchased Fe2O3 is a 'mixture' of different Fe isotopic oxides, meaning the catalytic effect of Fe2O3 is a synthesis of all isotopic compounds. The differences in catalytic properties of α-Fe2O3 with natural abundance ratio and separated isotopic α-Fe2O3 were investigated, and the results suggest that isotope effects are caused by nuclear morphology and charge distribution.

Summary: In this study, the abrasive wear characteristics of cotton grass reinforced epoxy composites were analyzed using the hand layup technique. The mechanical properties of the composites, such as tensile strength, hardness, and impact energy, were experimentally investigated and optimized. The results showed that the CG content had the most significant influence on the properties of the composites, followed by sliding velocity, normal load, and sliding distance. The worn surfaces of the composites were analyzed using scanning electron microscopy to study the potential wear mechanism.

Summary: This study characterises the dissimilar laser welding of shape memory alloy (NiTi) and copper (Cu) at different welding speeds by analysing the properties of the laser welds using various methods. XRD analysis shows the presence of NiTi, Cu, and NiTi-Cu phases in the welded zone. Microhardness testing reveals that the weld zone has higher hardness than NiTi and Cu base alloy. The welded joints have higher joint strength than Cu base alloy but lower strength than NiTi SMA, with the maximum joint strength achieved under specific laser power and welding speed conditions.
