  • - 6-Diphenyl-2-Cyclohexenone Lab Report

    In this experiment, a series of reactions was performed in order to synthesize 6-ethoxycarbonyl-3,5-diphenyl-2-cyclohexenone, an a,b-unsaturated ketone. The two reactions performed in order to obtain this product were a Michael addition reaction and an Aldol condensation reaction. During this experiment, the reaction solution underwent several changes. Originally, the initial solution was light yellow and transparent. Once heated, the appearance of the reaction solution became bright yellow.…

  • Synthesis Of 4-Nitrobromobenzene Lab Report

    resulting in a higher percentage. 2-NBB is less stable than 4-NBB, causing a lower percent yield. IR spectroscopy aids in determining the composition of a compound, allowing for identification. 2-Nitrobromobenzene was shown in product 1, but 4-Nitrobromobenzene could not be tested due to the small amount of product obtained. The two compounds can be distinguished by the peaks on the IR spectroscopy. 4-NBB contains an arene group, while 2-NBB contains an aldehyde/ketone group. The Thin layer…

  • Electron Microscopy Lab Report

    Using scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS) images and spectra were obtained from various samples of silica and platinum on silica. Each sample contains unique structures which were prepared by etching the surface of silica in different conditions. A scanning electron microscope is a type of electron microscope that produces images of topography and composition by scanning a sample with a focused beam of electrons. Samples can be observed in high vacuum,…

  • Scanning Electron Analysis

    The SEM produces a largely magnified image by using electrons instead of light to form an image. A beam of electrons is produced at the top of the microscope by an electron gun. It consists of an electron gun to produce high energy electron beam. A magnetic condensing lens is used to condense the electron beam and a scanning coil is arranged in-between magnetic condensing lens and the sample. The electron detector (Scintillator) is used to collect the secondary electrons and can be converted…

  • Analysis Of TRGO

    The progress of nanotechnology has encouraged scientists to continuously pursue new electrode materials for constructing an enhanced electrochemical platform for sensing. In this study, hydrothermally-assisted reduced graphene oxide (TRGO) was synthesized using an environment friendly reducing agent in optimum time to easily exfoliate coating solution and substitute on the microelectrode. Series connected distributed sensing electrodes were fabricated and patterned with TRGO added platinum…

  • Acetaminophen Analysis

    Abstract As one of the most popular analgesic and antipyretic, especially for pregnant women and children, acetaminophen is available over the counter in many forms. When consumed over long periods of time or in high dosages, acetaminophen has serious side effects including liver damage and other organ damages, therefore an effective quality control method of analysis. Here a method using cyclic voltammetry to analyze the concentration of acetaminophen in a liquid suspension Publix brand…

  • Legal Constraints In Forensic Science

    [19] and DNA typing [20], both aiming at the identification of crime victims or suspects/persons-of-interest. However, forensic science methods are beginning to far exceed such applications and often include various analytical methods, such as spectroscopy and electrochemical techniques, have seen tremendous developments. Modern developments are based on multi-disciplinary approaches involving not only physical techniques, but also computational methods. Collection and storage of samples into…
