  • Chromogenic Reagent Lab Report

    Overall the experiment provided significant data, despite problems with reagent contamination. Iron (III)-thiocyanate complexes in equilibrium, meaning that external and internal forces on the equilibrium can shift toward the reactants or the complex. External forces are changes to the chemical or physical environment that effect the equilibrium. Internal forces are changes to the bonds or chemical nature of the complex itself. These effects are used to study the optimal chromogenic reagent,…

  • Chemiluminescence Lab Report

    Molecules Project 1: Chemiluminescence Luuk Adema & Ewout van der Veer S2794640 & S2680254 luukadema@hotmail.com & ewoutvanderveer@msn.com 31-10-14 F. Mecozzi, E. Hagting & M. van Zuylen Abstract Luminol was synthesized and the light intensity of its luminescence was tested. The yield of the synthesis was 55%. Measurements of the intensity of luminescence were done under standard and optimal conditions resulting in peak intensities of ±0.02 lux (standard) and ±0.03 lux (optimal). It has been…

  • Haines Research Paper

    Paragraph 1 Compare and contrast the crystal structures and crystal chemistry of quartz, α-FePO4 and β-FePO4. Haines’ research paper studies the change that occurs in the FePO4 structure as it is studied from temperatures 294K to 1073K. A transition is noticed at 980K, when it’s tetrahedral α-quartz structure experiences high pressure levels, changing the structure to β-phase, a more dense octahedral structure. Cell parameters of FePO4 in α-phase increases in cell parameters and volume as…

  • Compare And Contrast The Crystal Structures And Crystal Chemistry Of

    Paragraph 1 (300 - 500 words) Compare and contrast the crystal structures and crystal chemistry of quartz, α-FePO4 and β-FePO4 To compare quartz, α-FePO4 and β-FePO4, it is essential to look at their crystal structures and crystal chemistry. This can be done by observing their three-dimensional structures as well as their reactions to various degrees of temperature. This particular research takes a look at the structure of FePO4 between temperatures of 294K to 1073K. At lower temperatures,…

  • Band Gap Vs. Lattice Constants Diagram For Hexagonal Nitride Lab Analysis

    Figure1.3: Band gap vs lattice constants diagram for hexagonal nitride compounds. The typical of measured band gap bowing for ternary alloys AlGaN and InGaN is shown by the solid line track[21]. 1.4. Unique Material properties of Gallium Nitride: The unique material properties of GaN engraves it as an prominent semiconductor material for many electronic and optoelectronic devices[18]. • The wide and direct energy band gap sorts GaN as an appropriate materials for device fabrication in the field…

  • Bovine Serum Albumin

    Introduction Bovine serum albumin (BSA) is a transport protein in cow’s blood stream, similar to Human serum albumin in human blood. It binds different types of drugs for delivery to various parts of the body. One of these drugs is warfarin, a blood anticoagulant. This research project’s focus was on the interaction between BSA and warfarin derivatives; our assumption was that the protein binding site has different affinities for different warfarin derivatives; this was to be determined by…

  • Eyring Factors: An Analysis Of Dielectric Loss Factor Values

    The dielectric loss factor was the most influenstic parameter in this microwave spectrum. The loss factor values increased as a function of frequency and slight modification in spectrum on changing the solute concentration. The ε˝ values obtained in our experiments are almost similar to our earlier work[43]. Above 8GHz the frequency dispersion spectrum of ε΄& ε˝ were superimposed with each other. The spacing between the dielectric values in dispersion spectrum could be attributed to…

  • Disadvantages Of Photoacoustic Spectroscopy

    Photoacoustic spectroscopy (PAS) is a tool to study thermal emission resulting from non-radiative relaxation followed by absorption of radiation. PAS was studied primarily by Alexander Graham Bell, John Tyndall, Wilhelm Rontgen and Lord Rayleigh in 1884. For the history of PAS, was not until 1975 that photoacoustic spectroscopy started to be used as a wide range of different applications. This technique provides the following main advantages over the known types of spectroscopy. The advantages…
