  • Chloroplast Lab Report

    Introduction In the Foundations of Biology lab section everyone had to investigate cell organelles and cellular metabolism. Every quad or tri group had to test for the activity of a chloroplast electron transport chain. The two choices that were available for us to investigate was broccoli and pea seedlings. Our group was nominated to utilize 20 grams of broccoli florets to find fractions that composed of an abundance of chloroplast. Project 1 had 3 parts to it; this consists of fractionation of cell homogenates, assay for chloroplast-specific electron transport chain activity, and testing factors that affect activity of the chloroplast electron transport chains. The first two parts of this project is Experiment #1, while part 3 is Experiment…

    It was noticed that the exp was in good acceptance with the theoretical value of PF leading to the conclusion that Frank-poole emission is the prevailing charge transport mechanism operating in these films. This can be due to the trap levels into the dielectric (Poole–Frenkel effect), which is responsible for the conduction through the charge carriers released from it, which enhances as the number of trap levels increases on increasing the time of reaction. This enhances the formation of…

  • Operating Principles In PEM Fuel Cell

    Hydrogen, which is fed into one side of the membrane, splits into its primary elements, i.e., one proton and one electron at anode. Protons will pass…

  • Parana Pine: An Analysis Of Young's Modulus Value

    most suitable component for structural application, because the 0.3% Mild Steel had the highest E/GPa value of 212.77 E/GPa compared with all the other materials used. Steel is a metal, so it is made up of metallic bonds, which means that the element largely consists of positive ions (positive charge) and delocalized electrons (free electrons of negative charge), the repulsion is balanced within the atom, a main reason to why metals are non-reactive to other elements. However one disadvantage…

  • John Thompson And John Dalton: The First Atomic Model

    His new model better described the structural components of the atom than Dalton’s featureless atom. Thompson used a Cathode Ray Tube, which was a sealed glass container, and shot a stream of electrons across the glass tube. When the particles stuck to the other end of the tube, it created a patch of light that indicated where the particles landed. Thompson discovered that by using a magnetic field, he could move and deflect particles. He found that particles would always move towards the…

  • Ultrafast Electron Microscopy Analysis

    Ultrafast Electron Microscopy has been demonstrated to be an effective table-top technique for imaging the temporally-evolving dynamics of matter with subparticle spatial resolution on the time scale of atomic motion. A stringent enhancement of the UEM temporal resolution is demanded for recording snapshots of the electron motion which will provide a real-time access to all microscopic motions outside the atomic core and radically change our insight into the workings of the microcosm. Here, we…

  • An Electric Circuit How Do They Work

    What is a circuit? How do they work? An electric circuit is a kind of path made up of wires that allows the flow of electrons. The circuit has to be made in a circular form, as the electrons must frequently move in a full loop, in which they will return to their original position and then complete the loop again. (“What is an electric circuit?”) The battery or another source of power provides the voltage, or ‘electrical push’, that makes the electrons move through the circuit. When the electrons…

  • Fepo4 Temperature

    Paragraph 1 The research done by Haines on how the atomic structure of FePO4 varies when temperature increases from 294K to 1073 shows few crystal chemical relationships between SiO2 and FePO4. There is a first order variation of cell parameters and atomic orientations with temperatures lower than 980K and α-phase plays a dominant role over β-phase at high temperature. For the α-phase FePO4, the cell parameters increase with a non-linear trend when temperature increases linearly. The volume…

  • Temperature Lab Report

    1 WRITTEN ESSAY Paragraph 1 The FePO4 crystal is examined at various temperatures ranging between 294K and 1073K by neutron powder diffraction. At relatively low temperatures, FePO4 adopts an α-quartz structure, which is tetrahedral. High pressures causes a phase change to a more dense octahedral structure, which is known as β-phase. The transition temperature is 980K. Cutoffs can be observed during the firstorder transition,. For α-phase, the increases in cell parameters…
