    gypsum crystal in the world are found in Naica Mexico mine’s Cave of Crystals. Crystals can be made in many different ways. Earth can either make them or they can be made artificially. Crystals can be made out of salt or borax. The earliest crystal grower was Earth. For salt crystal the water starts to evaporate the solution of the amount of salt in the glass that it remains the same. There is not enough water left to keep the sodium and chlorine ions from joining together (What Controls Crystal Growth

    Also, group 2 data was missing, we can estimate the value should be between Group 1 and 3. And I fixed the value at the same initial point, so we can see the change more directly. As it shown to us above, with the boron composition increasing, the solubility is decreasing. Conclusion From XRD we can get the glass is partially glass and partially crystalline. EDS shows the element composition of the glass, and the SEM pictures show us the microscopy image of the glass, and we can find a lot of crack

    Hypothesis: If forming rock crystals takes a specific composition of a solution, then how does a different solution of the sugar water and water affect the way the crystals form? Topic: Rock candy formation IV: I will experiment with creating different compositions of the ingredients needed to make rock candy. DV: I will measure the weight of the crystal in grams, and visually the size of the crystals. For my experiment, using different sugar solutions, such as sugar water that is 25% sugar, 50%

    A crystal is a solid whose atoms, or other components of matter, are structured in a uniform pattern as seen in Figure 1. This repetitive pattern forms an extending crystal lattice that gives crystals their unique geometric shape, known as the crystal structure. The crystal structure can be seen in Figure 2 below. The primary macroscopic characteristic of a crystal is its shape, typically consisting of flat faces, also known as facets, meeting at sharp angles. As a crystal grows, the new atoms attach

    abstract Photonic crystal is a composite dielectric with periodic modulation of refractive index that brings about unique photonic band-gap effect by which light could be totally reflected on the surface of such material regardless of any incident angle or mode. Such bandgap effect could be understood by investigating the optical performance of photonic crystals. In this paper, photonic bandgap calculations are performed for two dimensional photonic crystals using matlab. Plane wave expansion

    Introduction In many pharmaceutical industries, spray drying is used to create particles that are utilized to form many oral or inhaled drugs. Thus, these particles are designed to be pressed into tablets or dispersed in aerosols. A spray dryer is a processing unit that produces a mist where the solvent is quickly evaporated, leaving particles that are collected in a cyclone. This quick evaporation leaves the molecules fixed in their current positions, preventing the molecules from finding their

    Paragraph 1 Between α-FePO4 and β-FePO4, there are similarities and differences between the crystal structures and crystal chemistry. Starting off with the differences, one of which is how the quartz behaved at different temperatures. At low temperature, where the α-FePO4 is formed, generally tend towards the values obtained for β-FePO4 at high temperature. This is surprisingly true for all alpha quarts at low temperature, where they shift towards the value of its respective Beta quartz at high temperature

    156*10-12 m. Carbon atoms are 89 picometers smaller in radius than Iron atoms. Carbon atoms are considerably smaller than Iron atoms as they are smaller than half the size of iron atoms. Because of the small size of carbon, it will enter the iron crystal structure through interstitial diffusion. The Governing Equation for this diffusion is (C-Co)/(Cs-Co)=1-erf[ x/(2*(Dt)1/2)] . This an equation for a non-steady state diffusion process that has been derived from Fick’s Second Law which describes how

    Paragraph 1: Compare and Contrast between the crystal structures In this paragraph, we will be comparing between the crystal chemistry of the α- and β- FePO4, describing the crystallochemical relationship between the structure and how the structures are temperature-dependent. As FePO4 distinguishes itself from the other isotypes because the ion at the cathode is a transition metal. Transition metals have very low ionization energies, and often high melting and boiling points. When the temperature
