8.2 Fullerene Synthesis Lab Report

Better Essays
In September of 1985 Kroto, Heath, O’Brien, Curl, and Smalley were investigating sources of the long carbon chain molecules in the interstellar medium and how they might be related to soot formation.1 Smalley developed a laser vaporization cluster beam apparatus that allowed for the mass-spectrometric study of stable clusters formed in a helium-entrained plasma produced by a pulse of laser aimed on at a solid target.2 This experimental technique was a very important discovery to cluster science because it made refractory clusters available for detailed study for the first time.2 Smalley initially used this technique to analyze the molecular structure of SiC2, but Kroto decided to replace the SiC2 with graphite.2 He believed this technique …show more content…
The main advantage to using this method is that it has a lot of synthetic control.3 Fullerene precursors with nitrogen heteroatoms installed on them can be synthesized, and after the fullerene has formed the nitrogen will stay in it’s preselected place.3 This allows for making very specific fullerenes that could be needed for other reactions.3 For example triazafullerene, C57H33N3, has successfully been created using this method.3

This is a step toward a potential route to hetero- and endohedral metallo-fullerenes; as well as adapting this synthesis in a way so they can encapsulate small molecules inside the fullerene.3
While scientists are still presently researching ways to adapt the surface catalyzed synthesis; Kurotobi and Murata discovered a synthetic route to insert a single water molecule into a

    Here we will discuss about Claisen ester condensation reaction. 1. Claisen ester condensation – Here we are taking specific example of Ethyl acetate (CH3COOET). When ethyl acetate is treated with strong base like –OET and then the reactants are refluxed then they produces a β-keto ester via several steps. In this case also the last step is most important because it helps to drive the equilibrium of every step in the forward direction.…

    Electron Motion Control and Imaging M. Th. Hassan Electron motion in atomic systems, which happens on timescales of attoseconds (10-18s), is at the heart of all phenomena in nature. For instance, the motion of electrons in the chemical bonds determines the structure change in the molecules. Therefore, controlling this fast electron motion, in turn, allows to control the molecular structure change. Additionally, recording snapshots of the electron motion will provide real-time access to all microscopic motions outside the atomic core and radically change our insight into the workings of the microcosm, which will improve our understanding of chemistry.…

    Therefore we can see that stars are just atoms (hydrogen) hitting each other producing light. Scientists know what stars are made of through the use of the atomic model, spectral lines and quantum mechanics. The atomic model is critical to understand what stars are made of. Matter is comprised of atoms, which are particles made up of electrons, protons and neutrons.…

    Monolayer-Mos2 Case Study

    In recent years, defect engineering has emerged as an effective strategy to tune various properties of 2D materials such as graphene, hexagonal boron nitride and silicene [19-21]. Like other 2D materials, intrinsic structural defects including point defects, grain boundaries, dislocations and edges can be realized in MoS2 either during the growth process [22, 23] or intentionally introduced through electron irradiation process [24], which are possible to modulate materials properties and also provide an opportunity to explore new functionality. For instance, the defects like VMoS6 vacancies are found to be highly reactive and could significantly promote the electronic and catalytic activity of the basal planes [26]. The S-vacancy is found to be the most preferred catalytic site for the adsorption of nonpolar gases like CO2 and CH4, in comparison to other stoichiometric sites [27]. On the other hand, monolayer MoS2 exhibits similar mechanical property to graphene, thus strain can serve as another means to modulate and optimize properties.…

    In pursuit of our continued interest in the development of solvent-free and green synthetic procedures, we decided to explore the use of tartaric acid catalyst for synthesis of polysubstituted quinolines via Friedlander condensation in high to excellent yields at 70 °C under solvent-free conditions. Initially the reaction between 2-aminobenzophenone (1.0 mmol) and dimedone (1.0 mmol), as the model reaction was examined in the presence varying amount of tartaric acid as catalyst and the results are presented in Table 1. The best result was achieved by carrying out the reaction with 15 mol% of catalyst (Table 1, entry 4). Use of a higher amount of catalyst did not improve the yield while a decrease in the amount of catalyst decreases the yield…

    During this time physicists were now able to mimic cosmic rays in machines that could accelerate protons and electrons to high energies. This made them easier to study because they could be studied at controlled conditions. This machines came to be due to a small group of scientists in Cambridge and California to create the first artificially accelerated protons. This work in the 1930s lead to the development of the machines used in later experiments. These machines were then able to produce millions of protons, electrons, pions and kaons per second.…

    I have extended the light filed sculpting over more than two octaves in the visible frequency and flanking ranges to generate the first optical attosecond pulse (OAP) (carried at central wavelength =530 nm and FWHM of instantaneous intensity (380as), Fig. 1b). This is a new tool in the science of light that combines the energy range and the power of few-cycle pulses and the temporal resolution of a EUV attosecond pulses. The ability to control the field of the OAP offers direct drive and control of bound electrons motion in atoms, molecules, and nanostructures with attosecond precision. I have used the field-controlled OAP to reveal the nonlinear response time of bound electrons in a krypton atom which is in the order of hundred attoseconds (Nature, In Revision).…

    Dmitri Mendeleevs development of the periodic table is the foundation of chemistry. The periodic table has contributed to the experiments and discoveries of many famous chemist such as Joseph Proust who studied chemical compounds and created the law of definite proportions or Robert Boyle who studied the characteristics and behavior of gases. Dmitri Mendeleevs periodic table has also made a major impact on modern day science. The periodic table has helped chemist find missing and unknown elements. In the biography on Dmitri Mendeleev it says, “Scientists continue to adjust the periodic table as new elements are found.…

    The husband and wife team of Pierre and Marie Curie became interested in Becquerel’s discovery (The Discovery of Radioactivity). While experimenting with their own uranium-containing ore, they came up with the term "radioactivity" to describe the spontaneous emissions that they studied (The Discovery of Radioactivity). That word helped shape how we view the world forever. Radiation became the newest scientific find, however it flew under the radar for a bit, until we figured out how to power and destroy things with it. Ernest Rutherford made the next important discovery.…

    Erwin Schrödinger, an Austrian born chemist, gained his famed for his contributions to quantum mechanics. Some of his contributions to chemistry and quantum mechanics were his books describing his techniques and basic info behind his work, his paradox, Schrodinger’s cat, which created a lot of new discoveries in chemistry, and his equation that changed how many people viewed the atom and its electrons. At at young age, Schrodinger was strongly influenced by the philosophy of Austrian philosopher Arthur Schopenhauer (Mastin, Luke. "Erwin Schrödinger - Important Scientists - The Physics of the Universe."). Born on August 12, 1887, Erwin Schrodinger grew up in Vienna and attended the Akademisches Gymnasium High School in his teenage years and…
