In this research work, a novel approach has been applied with respect to powder metallurgy route for the development of aluminium–graphene nano–bio composite materials for the application in bone research. The applied technology has been executed to synthesize Aluminium- Graphene composite materials with the help of high energy ball milling process followed by vacuum sintering to get the required devices. The fabricated devices and synthesize composite materials at later stage have been evaluated in terms of different micro-structural characterization tools like FE-SEM (Field Emission Scanning Electron Microscope), EDAX (Energy dispersive X-ray analysis) etc. for qualitative and quantitative analysis, which shows well distribution of the constituents of Al-Grapheme composite materials over the scan areas. The physical property of the sintered samples has also been evaluated through density measurement and it is found to be ≈ 97.5% density after sintering. The thermal fusing of Al based materials at the optimum temperature of sintering is found to be satisfactory with required strength. These nanobio- congruent composite materials, which is carbon based can instigate and assist stem cell improvement and differentiation into diverse lineages. Moreover, the 2-dimensional material, graphene has the potential propensity to stimulate and escalate osteogenic differentiation, which makes it an exciting material for the bone regeneration research.

Although static electricity is commonly utilized in devices such as photocopiers, it often results in malfunction or failure in electronic equipment. When a conductive object housed in a partially opened box is positioned near a charged object, electrostatic induction causes the conductive object to become electrified. For instance, the human body becomes electrified when a person stands up and moves away from a chair. In this experiment, induced voltages generated in different types of boxes were measured using an induction electrode, paired with a spark gap and an electromagnetic wave sensor, as a charged body moved away from the box. The findings indicate that an electrostatically induced voltage ranging from -0.27 to -0.44 times against the voltage of the charged body is generated in the box when the distance between the charged body and the box is 0.02 m. These results are valuable for mitigating the risk of malfunction or failure in electronic equipment.
