    regular light and shadow images and objects can be made visible on a fluorescent screen coated with barium platinocyanide. When an x-ray passes through a substance‚ diffraction phenomena occur that reveal the wave character of radiation. An interference pattern composed of dots can be formed on a photographic plate. These diffraction patterns were 1st studied by M. Von Laue‚ known as the Laue "x" patterns.(Simon and Schuster) Over time the world has created many pieces of technology that are important

    Title Freezing and Melting Point Objectives 1. To gain proficiency in constructing a graph and plotting data points. 2. To determine the freezing points of a compound from the graph of decreasing temperature versus time. 3. To determine the melting points of a known and unknown compound. Introduction Physical changes are the changes in the physical properties of a substance (Moore‚ Stanitski & Jurs‚ 2009). Freezing point is the fixed temperature at which a pure liquid converted into crystalline

    development of pharmaceuticals that can enhance or inhibit certain proteins in a variety of signaling pathways. To determine protein structures‚ a general protocol of steps must be followed. Proteins must be purified‚ crystallized‚ and then through x-ray diffraction techniques a structure can be determined. However‚ the most crucial part of structure determination is the crystallization of a protein. A protein can be difficult to crystallize because an optimal environment must be found by adjusting temperature

    Experiment 9: THE TANGENT GALVANOMETER; PURPOSE: In this experiment we will measure the magnitude of the horizontal component of the Earth’s Magnetic field by the use of an instrument called a tangent galvanometer. INTRODUCTION: A tangent galvanometer consists of a number of turns of copper wire wound on a hoop. At the center of the hoop a compass is mounted. When a direct current flows through the wires‚ a magnetic field is induced in the space surrounding the loops of
