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.
AZoNano - The A to Z of Nanotechnology - Schematic of a buckytube or carbon nanotube
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.

Everyday application of Hess's Law

  Everyday application of Hess's Law Burning calories, consuming food, driving home, we all should be familiar with these actions because we do them everyday, but what some of us don't realise is that all these actions related one fundamental law of conservation of energy, Hess's Law.   Hess's Law states that: regardless of the multiple stages or steps of a reaction, the total enthalpy change for the reaction is the sum of all changes. [1]   We will further discover how our indrustries, human body and drug production are related to this law and to better understand the science behind it. Industries Today, all our mass and low cost production depends on factories and industries and all these industries require huge amount of energy.   To keep everything the most efficient possible, these industries has to determine the method that is the most effective to produce a product based on the energy needed or released.   For example:  Car companies...

Antoine Lavoisier and his contribution to Chemistry

The French Bourgeoisie helping out with science: “In performing experiments, it is necessary… that they be simplified as much as possible, and that every circumstance that could complicate the results should be completely removed.” -Antoine Lavoisier Early life and Work: On the 26 of  August 1743, Antoine Lavoisier was born to a wealthy family of nobility and was the son of an attorney at the Parliament of Paris. He  went to school at the College des Quatres Nations, University of Paris at the age of 11 were he studied chemistry, botany, astronomy and mathematics and received a law degree which admitted him the bar. (1). This French nobleman, chemist and biologist is credited for being the first one to put an extensive lists of the elements, helping construct the metric system and reform chemical nomenclature. Lavoisier is also known as the “ father of modern chemistry” (1). Lavoisier who was originally part of the Ferme generale ( most hated components...

Are physical properties such as temperature invented or discovered?

TOK Blog Are physical properties such as temperature invented or discovered? Even tho we don’t know exactly how temperature was invented or discovered we know for sure the Galileo Galilei was the first human being that came up with the idea of an instrument able to calculate the temperature know as a thermometer. Many scientist don’t really recognize Galilei’s instrument as a thermometer but, more as thermoscope because his device only showed the change in temperature and had no scale .The measurement of temperature consist of “The process of measuring a current local temperature for immediate or later evaluation.” Celcius In 1742 two years before his death Celcius created a scale which was reversed a 0° represented the boiling point of water and 100° represented the freezing point of water. Kelvin In 1848, William Thomson created the Absolute Thermometric Scale that could measure the absolute zero as the scale's null point, and in which he used the Celsius as...
