Carbon nanotube's revolution


 Chemists felt there was nothing more to learn about carbon, until the late 1950s,  when a new allotrope of carbon was discovered.  Then years after years, the research continued until today where this technology can be used in nanotechnology, electronics, optics and other fields of materials science.

Here is how a carbon nanotube should look like.
Something that made the carbon nanotube interesting is that the nanotubes are shaped like a cylinder. The composition is that every carbon atoms is linked in a hexagonal shape, with each carbon atom bonded to three other carbon atoms. Carbon nanotubes have diameters as small as 1 nm and lengths up to several centimeters and it has exceptional material properties, such as very high electrical and thermal conductivity, strength, stiffness, and toughness. This makes the carbon nanotube dense but small, due to this property, construction companies and even NASA is combining carbon nanotubes with other materials to try to build a lightweight but strong spacecraft.

Was density invented or discovered

-
To begin with, what is the difference between invented and discovered? “A discovery is recognizing something that already exists for the first time, that nobody has found before, e.g. how Christopher Columbus discovered the Americas. An invention is creating something totally new with one's own ideas and development. Although an invention is completely new to the world, the physical material needed for its production already exists, e.g. how Thomas Edison invented the light bulb.” Density is a physical property of matter that expresses a relationship of mass to volume. The more mass an object contains in a given space, the more dense it is. “ Sometime around 250 BCE, the Greek mathematician Archimedes was given the task of determining whether a craftsman had defrauded the King of Syracuse by replacing some of the gold in the King's crown with silver. Archimedes thought about the problem while relaxing in a bathing pool. As he entered the pool, he noticed that water spil...

Niels Bohr and his Contributions to Chemistry

Chemistry SL November 8, 2018 Niels Bohr and his contributions to Chemistry Niels Bohr Niels Bohr was a Danish physicist born in 1885. He came from a very well educated family, and attended Copenhagen University to pursue a career in Physics. He was able to obtain his Masters degree at the age of 23 and his Doctorate at the age of 25. He was also the winner of the Nobel prize for Physics in 1922. Due to his many contributions to Physics and other scientific fields, he is widely regarded as one of the greatest scientific minds of the 20th century. While his expertise lies mainly in Physics, he also made several monumental discoveries for Chemistry as well. He was the first to realize that elements in the periodic table had unique chemical properties, which was a direct result of the number of electrons the atom could hold. He was also the first to theorize that electrons could move from a higher orbit to a lower one, and that energy will be emitted in the process. His work w...

Mendeleev’s periodic table contributions

Dmitri Mendeleev, born 8 February 1834, was a russian chemist and inventor often credited with the formulation of the periodic table, one that is continuously used in science to this date. Mendeleev, however, did not create the periodic table from scratch, rather he improved on pre-existing notions to create one that would not be in error as new elements were discovered. Through deduction, Mendeleev realised that the relative atomic mass and properties of an element occur periodically, and many of these properties, when the elements are arranged by their atomic mass, repeat themselves, such as chemical properties of Lithium recurring in Sodium such as their reactivity with water, and once again in Potassium later on. This lead to the creation of the Periodic Law. This law, initially, was only an empirical concept and could not be proven, it was merely suggested in research done by scientists at the time. Technological advancements today and the development of the electronic...
