Allotropes of carbon

The World witnessed a struggle for the control of oil in 1973, the decisions of which ultimately lead to globalization. As America saw the pace of life quicken in the twentieth century with the use of cars, planes, airplanes and appliances, the demand for oil to fuel this development increased. Believing that there was endless energy, the American way of life had an insatiable appetite for oil. Up until 1950 the United States had been able to supply its own energy needs, but in less than 25…

In 2010, St. Patrick's Day started out as a normal day for Jamie Laiaddee. She had gotten her oiled changed at Greulich’s Automotive, local mechanic, and was expecting to start her new job the next day a year after being laid off. The 32 year old had no idea that she would drop off the face of the earth. A California girl, Jamie was born in Los Angeles on October 12th, 1977. Her family, of Tai decent, had made the decision to move to the United States in search of a better life. Jamie was a…

The human body is mainly made up of four elemental components: oxygen (65%), Carbon (18%), Hydrogen (10%), and Nitrogen (3%). It is also composed of about 28 other elements including, Potassium, Sodium, and Calcium. Each plays a major role on the daily functions of the human body. Oxygen accounts for roughly about two-thirds of the mass of the human body and is use in cell respiration. Carbon is part of the molecular structure in certain fats, proteins, and carbohydrates; which are essential…

Theq element on the Periodic table that is best representation of my personality would be element 13, Aluminum. Properties of Aluminum its included high melting point, conductivity, malleability, and non-toxicity. Aluminum’s high melting point represents my determined personality. This is because I can face adversity well. Even when situations occur that are extremely unfavorable I am able to keep a cool head and think straight. I can persevere and stay strong allowing myself to solve and get…

Experiment 5: Anions and Redox Reactions Introduction (a) Objectives General: To examine the importance of potassium permanganate as an oxidising agent and the strong powers of halogens in oxidation. Part 1 Determining the colour associated with a certain halogen by adding a sample of the halogen to cyclohexane and recording the colours observed. Part 2 Identifying a halogen referring to the colours recorded in part 1, by reacting the halogen with a halide and observing the colour present.…

3.4. Friction Characteristics of the NCD, MCD and boron doped NCD Coatings against Alumina Balls The friction coefficient curves of NCD, MCD and boron-doped diamond films sliding with Al2O3 balls are shown in figure 4, figure 5 and figure 6, respectively, for a sliding speed of 8 m/s and a load of 1N, 5N and 10N, respectively. Figure 4 (a), figure 5 (a) and figure 6 (a) show the friction coefficient of NCD, MCD and BDNCD at 1 N, respectively. Figure 4 (b), figure 5 (b) and figure 6 (b) show…

Chalcone and Pyrylium Syntheses and Analyses Done by: Natalie Almond & Sophie Troyer in approved collaboration Introduction Photoredox catalysis uses light to excite the catalytic compounds, producing an effective oxidizing agent.1 The oxidizing agent can remove an electron from the desired compound for reaction, making it easier to synthesize molecules.1 One example of the utility of photoredox catalysis is the “production of lignan cyclobutanes,” which have many important pharmaceutical…

 Comment: The three bonds (one solid line, one wedged line and one dashed line) that are attached to the + carbon atom are turned inside out. If the starting material has Br on the right side of the + carbon atom, the final product will have OH on the left side of the + carbon atom and vice versa.  Comment: There is only one hump for the energy profile of an SN2 reaction. As we shall see later, there are two humps for the energy profile of an SN1 reaction. One easy way to…

Then push your fruit peels, coffee grounds, spoiled vegetables, even small chicken bones down the disposal. The disposal…

Main Group Elements Organometallic Compounds: The compounds which contain at least one direct metal to carbon covalent bond are known as organometallic compounds many of these are thermodynamically unstable and are pyrophoric. The meta may belongs to main group, transition metal, f group metal or a metalloid i.e. selenium, boron, arsenic, silicon, antimony, germanium, and tellurium and the carbon moiety may be alkyl, alkene, alkyne, carbonyl, cyclic, heterocyclic or aromatic.1 Historical…
