What is it about?

Our findings show that the social strategies of group-living animals can be adjusted over very short time periods - within a day. Thus, the social strategies of baboons are much more flexible than previously appreciated. This research was about conducting nano cupric oxide coating by using the electrochemical anodizing technique in oxalate solution. It evaluates the effective parameters on the hardness and hydrophobicity of the nano-CuO coating. In addition, to evaluate the optimum coating parameters for the best coating heat transfer performance.

Why is it important?

It develops super hydrophobic surfaces, gas detectors, solar cells, corrosion protection, super-capacitors, fuel cell, batteries, radar-absorbing coating, and memory storage devices. Our findings show the thermal effects of the Nano anodized coating were evaluated according to the coating’s grain size and porosity, which formed at various oxalate concentrations. The result shows that Nano anodized coating improves the thermal efficiency of copper by 96.5 % as a result of the increment in the heat transfer surface area around 350 times.


Writing this article was a great pleasure as it has co-authors with whom I have had long-standing collaborations. This article also leads to rare disease groups contacting me and ultimately to greater involvement in rare disease research. I expected this study to contribute to the knowledge development of hydrophobic surfaces, gas detectors, solar cells, corrosion protection, supercapacitors, fuel cell, batteries, and memory storage devices. Moreover, this study can support the development of other applications such as EMI shielding, radar absorbing properties of stealth technology.
