  • Spectroscopy And Molarity

    technique of spectroscopy; spectroscopy can be defined as the science affiliated with the spectra produced when matter interacts with light. Lab 7 investigation 19, “What Factors Affect the Intensity of Color?” expands on the process of spectroscopy, and its relation to the molarity of a substance. The goal of this lab was to determine the effects of the intensity of color of a solution (2). Spectroscopy is frequently used in the medical field by using the process of infrared spectroscopy, which…

  • Physics Of Q-Dots Lab Report

    Introduction Quantum dots (Q-Dots) is very small semiconductor particles that means it can be either conductors or resist electricity depending on the temperature and purity of the semiconductor. Q-dots range in size from 2-10 nm, so because of their small size, quantum mechanics governs the physics of the particles. The synthesis Q-Dots were first studied in 1982 by Efros and Ekimov, and then many developments have reported the synthesis of semiconductor nanoparticles.1 Q-Dots have unique…

  • Friction Characteristics Of NCD Vs Alumina Balls Analysis

    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…

  • Ethyl Cinnamate Lab Report

    cinnamate, cinnamic acid, and glucose, which are ingredients in the candy, Red Hots. The experiment began with 0.604 grams of a mixture of ethyl cinnamate, cinnamic acid, and glucose. The purity of glucose and ethyl cinnamate was measured through IR Spectroscopy. Melting point was used to determine the purity for cinnamic acid. Using the final amount for each ingredient, we determined the percent yields, which were 64.7% for glucose, 56.2% for cinnamic acid, and 38.8% for ethyl cinnamate. The…

  • Lefloxacin Cocrystals Lab Report

    centrifuged and filtered through 0.45 µm filter, diluted suitably and analysed using UV-Visible spectrophotometer (Systronics, India) at λmax of 227nm. All observations were done in triplicate. Fourier Transform Infrared Spectroscopy (FTIR) Fourier Transform Infrared Spectroscopy was performed to characterize and investigate the interaction between levofloxacin and coformers stearic acid and saccharin sodium used. The FTIR spectra for pure levofloxacin, stearic acid, sodium saccharin, L-ST1 and…

  • Nucleobases Lab Report

    Review of Stacking Interactions of Nucleobases: NMR Investigations by H. Sapper and W. Lohmann Introduction Nuclear magnetic resonance (NMR) spectroscopy is often a very useful tool to identify organic molecules based on the atomic nuclei interactions with their environment. Recent advances have made use of the technology in protein, nucleic acid, and complex natural products structure identification. [1, 2, 3] Its origins lie in the works of Felix Bloch and Edward Purcell, who used the…

  • Ethyl Cinnamate Synthesis

    Experiment 5 Synthesis and NMR Spectroscopy of ethyl cinnamate Introduction: Wittig reactions involve the stereoselective synthesis of olefins from phosphonium ylides and aldehydes or ketones, where the carbonyl bond is converted to an alkene double bond.1 The variety of suitable reagents and the relatively mild experimental conditions facilitate their industrial applications, such as the synthesis of epoxides, esters, carotenoids and vitamin A.2,3 Specifically, the ester ethyl cinnamate is used…

  • Summary On Zinc Oxide Nanoparticles With Defects

    When EPR spectroscopy is applied, two types of paramagnetic signals have been observed. The low field signal with g = 2.0023 and the other high field signal at g ˜1.96, both are associated with unpaired electrons trapped on oxygen vacancies. It is found that the intensity…

  • Optical Tweezers Lab Report

    5.2 Discussion 5.2.1 Comparison of the results from AFM and optical tweezers experiments Different unfolding behaviors in AFM and optical tweezers experiments In chapter 3, we have studied AFV3-109 using single-molecule AFM. The results from optical tweezers are contradictory to the results from AFM. First, the unfolding force obtained by optical tweezers is much smaller than the force obtained by AFM. More importantly, in our previous study using AFM, the unfolding of AFV3-109 occurs in…

  • Body Synthesis Protocol Analysis

    Chapter Three - Conclusions 3.1 Conclusions This research aimed to verify the synthesis protocol for HPA-12 and analogues from aldehydes of Greatrex et al. (2014). Limited success in synthesising required quantities had a negative impact on the outcomes of this research, and no reasons were identified for the low yields that were obtained. Additional time, or resolution of issues resulting in low yields, would have allowed additional research and confirmation of the synthesis protocol. Long…
