1. INTRODUCTION Graphene consists of single layer of carbon atoms arranged in a hexagonal lattice. It is the basic structural element of many other forms of carbon, such as graphite, charcoal, carbon nanotubes and fullerenes. In simple terms, graphene, is a thin layer of pure carbon bonded together in a hexagonal honeycomb lattice. It is the thinnest compound known to man, the lightest material known, the strongest compound discovered, the best conductor of heat at room temperature and also the…

Intermolecular Forces Intermolecular forces are the result of attractive or repulsive forces between atoms, molecules or ions, primarily as a result of electrostatic attractions; these forces act between discrete molecules. Intermolecular forces are weak forces but without them life as we know it would not be possible: water vapor would not condense into its liquid (or solid forms) if its molecules did not attract each other, and all matter, in fact, would exist as gases. The physical states…

According to R.A Aitken, “An asymmetric synthesis may be defined as a synthesis in which an achiral unit is an ensemble of substrate molecules is converted to a chiral unit such that the possible stereoisomers are formed in unequal amounts.” It relates to any synthetic process that incorporates one or more new elements of chirality during a functional group transformation. Asymmetric synthesis involves the formation of chiral molecules. An object is said to be chiral, if it cannot be…

about the single bonds. There be terms used below such as eclipsed conformation, staggered conformation,dihedral angle and a few more. Eclipsed conformation is the conformation whereby the C-H bonds on one carbon is directly aligned with the C-H bonds of the adjacent carbon. When the C-H bond of one carbon bisects the H-C-H bond on the adjacent carbon, it is known as staggered conformation. Dihedral angle is the angle which separates the the bond on carbon atom from another bond of the adjacent…

This study analyzed the different forms of news coverage pertaining to the steroid era in Major League Baseball, along with the fan’s opinions of Barry Bonds, Mark McGwire and Rafael Palmeiro. These three players previously tested positive for steroid use throughout their time in the Major Leagues. While all three of these players showed remarkable talent throughout their Major League careers, their statistics will always be tainted, which influences peoples opinions on whether or not they…

Although Margaret M. Goss started her professional life as a nurse, she always knew she had a passion for writing. Her very first novel, The Uncommitted took her nine years to write and publish and she isn’t stopping there. ("About Margaret.") She has a very chaotic life and still plans to publish the sequel by the end of 2017. ("Re: Student”) While working as a nurse, raising three children, and everything else she managed to finish the novel and win some awards. She received the Midwest…

In the article “Let Steroids into the Hall of Fame,” by Zev Chafets the author strongly supports the use of steroids in baseball. The overall theme of the story illustrates the concept of steroids shaping the way we know baseball today, with it’s concerning influence on the youth who view players as their role models. The author begins with the background history on steroids in baseball and supports the claim that players have altered the game since the beginning, as many of the famous players…

1. Is mercury an appropriate target for AGI? Why or why not? Please clearly cite examples for your reasons. (10 points) There are many reasons that mercury is an appropriate target for AGI. • Both companies are in the same industry of footwear products. • First off the two companies have differentiating strategies and markets that they sell to. AGI will be adding a new market to their company goals and increasing their revenue streams. • AGI strives in the casual footwear segment with a…

INTRODUCTION Background The macrocyclic organic molecules Phthalocyanines (1) which are comparable to the naturally occurring porphyrin (2) ring systems shown in (Figure 1). The porphyrin molecule consists up of four pyrrole subunits which are associated in n-conjugation by methine carbons. 1 2 Figure 1: structures of phthalocyanine and porphyrins molcule The compound…

covalent bond with middle metal atom. Ligands have one electron pair to donate to a metal atom and are called complex agents. • Metal atoms are Lewis acids because they can accept pairs of electrons from Lewis bases. • Within a ligand, the atom that is directly bonded to the metal atom/ion is called the donor atom. • A coordinate covalent bond is a covalent bond in which one atom (i.e., the donor atom) gives both electrons. This type of bonding is different from a normal covalent bond in which…
