The Discovery Of The Guatemalan Archives - sorry, that
Ancient Egypt was a successful culture for over 3, years. Each had a ruler and their own religious beliefs and ways of doing things. After the two kingdoms were united, they became a lot more. This was a class system and each person living in ancient Egypt knew where they existed in the system and had specific rights of that class. The Ancient Egyptian hierarchy was a lot like the pyramids that they built. At the very top of this social structure was the pharaoh and their gods. Since the pharaoh was thought to be a god, he took his place next to all of the others. The gods were thought to be in control of the flooding of the Nile each year, as well as death and famine. The pharaoh was also in charge of the armies and any laws that were decided upon were the responsibility of the pharaoh.The Discovery Of The Guatemalan Archives - are mistaken
The research, published recently in the journal Scientific Reports , revealed that these coatings are made of carbon nanotubes CNTs which have enabled the layer to last more than years, raising questions on the tools used during those periods to achieve high temperatures for making earthenwares. CNTs are tubular structures of carbon atoms arranged in an ordered manner, Chandrasekaran said, adding that coatings in ancient artifacts may not usually last this long due to wear and tear caused by changing conditions. Carbon nanotubes have superlative properties, including high thermal and electrical conductivity, and very high mechanical strength, explained nanomaterial scientist M. Rajavelu S, Professor of History at Alagappa University in Tamil Nadu, who was unrelated to the study, told PTI that the people of this time may have added or coated something similar to plant-sap to the inside of the pots, and subject it to the nearly degree Celsius high-temperature fire treatment as seen in kilns. Commenting on the significance of the research, Sharada Srinivasan, an expert in archaemetallurgy associated with the National Institute of Advanced Studies NIAS in Bengaluru, said nanotechnology has made strides since the 90s with the advent of advanced techniques like the scanning tunnelling microscopy. Based on their analysis, Chandrasekaran said the ancient Tamil civilization of this time were aware of, and mastered high-temperature processing, but added that the means and mechanism by which they produced these artifacts with carbon-nanotubes is not widely explored. She believes the findings expand the broader knowledge of the history of science and technology in India, and point to potential future applications of such nanomaterials as durable coatings.
