Isotopes of carbon

Throughout this exhibition, I have created one specific theme—to take you through the technique of gilding and the material of gilt bronze. Gilding or Ormolu is a “decorative technique for applying fine gold leaf or powder to a solid surface such as wood, stone, or metal to give a thin coating of gold.” In this case, the exhibition will revolve around gilt bronze Asian artwork. Let us take a tour through multiple pieces and learn about the gilding technique, and how the material has held up…

If you are an avid fisherman, you need equipment that can keep up with your hobby. The Shimano Complex saltwater spinning reel provides you with the service and comfort you need for everyday or occasional fishing. This accessory is part of Shimano's Quickresponse Series. It is designed to be both lightweight and durable. Despite the light weight of this spinning reel, it provides remarkable stiffness. Shimano is moving from aluminum to graphite in their reels, so they benefit from modern,…

The United States uses over 18 billion barrels of oil every day. This means in turn that a country with just 4.5% of the world's population, is using about 20% of the world's oil. The United States only produces 8 million barrels of oil per day, which is the foundation of the nation's great dependence on foreign oil. One of the largest uses of oil is for gasoline in cars, which can be completely gotten rid of as a whole, There are currently multiple alternatives to fuel cars as opposed to…

Where does most oil come from? Where does the least amount of oil come from? Oil and gas is in very many areas in the planet, but in some places there is lots more than others. Oil and gas comes from many areas in the planet, but in some places there is more than others. According to worldmap.harvard.edu,” Most gas and oil comes from Africa,Europe, Asia, and Russia. Also, America ,South America,and Canada have lots of oil and gas, but not as much as the other places.” In other words, The U.S. ,…

the capacity to combust in the company of basic substances such as ammonia or sodium cyanide. What is its structure? The structure of Hydrogen cyanide is H-C≡N. HCN is a linear molecule and has a triple bond between Carbon and Nitrogen which is strong whereas Hydrogen and Carbon are connected by a single bond making the bond weak. HCN as has a 180° angle. What are its physical properties? Molecular weight 27.0253 g/mol Molecular formula HCN Colour Colourless gas Odour Sweetish Taste…

metal. Thankfully, there are numerous minerals in Magnesium. Two of the most common minerals are dolomite and magnesite. These minerals and the element itself can be discovered in sea water. Saying this, come and see what its origin of name is, its isotopes, five main characteristics, and more! First off, the origin name of a magnesium is the greek word, magnesia. A fun fact about the element is that if you add water to a magnesium fire produces hydrogen…

Dr. Andrzeij Sygula Research Dr. Sygula research is on polycyclic hydrocarbons called buckybowls. Due to their non-planarity, these moleules resemble fragments of fullerene, hence the name buckybowl. The smallest buckybowl to date is coronnulene, a non-planar hydrocarbon made up of five overlapping 1, 3-cyclohexadiene rings figure 1. The synthesis of coronnulene in lab is very challenging primarily because of the stress associated with the non-plannar molecule. Dr. Sygula’s lab accidentally came…

The molecule butane was observed while its dihedral angle was changed in 60 degree increments from 0 degrees to 360. The dihedral angle that had the largest potential energy was at 0˚ and 360˚. This is because the molecule was in an eclipsed conformation, an orientation of the molecule that causes there to be a lot of potential energy because the two largest molecules are fighting space, making it unstable. The lowest potential energy and most stable conformation was seen at 180˚which is…

Earth glaciations as the theory of snowball earth states a frozen sea must be present (Hoffman, et al., 1998). It does not however dictate that the continents also must be entirely frozen. However for no hydrological cycle and thus no weathering or carbon dioxide draw down to occur most continental areas would have to be covered by at least thin ice sheets. This is evidence that the seas remained anoxic throughout the snowball glaciations. If these glaciations can be attributed to δ13 C…
