  • Al2o3 Economic Impact

    In this essay, I will explain how we can benefit from bonding of atoms of certain elements in our daily life. As I will show in this essay, with the help of understanding the surface chemistry, which is the study of chemical reactions at interfaces (surfaces), different desired affects can be produced by the formation of selected elements such as making improved chemical composition of a surface. Surface chemistry today can be applied to solve various issues and problems including fighting…

  • Case Study: Transition Metal Complexs Of The Macrocyclic

    Results and dissection 3.1 Transition metal complexes of the macrocyclic, H6L Ligand 3.1.1 The macrocyclic, H6L Ligand The physical and analytical data of the macrocyclic, H6L ligand and its transition metal complexes were shown in Table 1. From the investigation, the expected structure of H6L with its possible toutomeric forms can be represented as shown in Figure 1. H6L ligand is highly symmetric under the point group C2v symmetry and can show all the normal modes of vibrations by solving…

  • Nay Zeolite Essay

    over 3, which is not achievable through direct synthesis [4]. Zeolite dealumination was introduced regarding instability of the framework in acidic and aqueous media [5, 6], and could be conducted by acid extraction [7], Al/Si substitution [8] and thermal treatment of ion exchanged NaY zeolite [9]. Not all zeolites can survive and maintain their framework structure and stability after dealumination [10]. NaY zeolite with Si to Al ratio of…

  • Disadvantages Of Syngas

    Syngas, though has lower energy contents when compared with methane, which has been previously utilized [17-24] as reactive gas in OTR. Notwithstanding, syngas is considered in the present work due to its great stability and predictability, high thermal and electrical efficiencies, can be produced from renewable sources and has reduced carbon emissions. Mesh of 36000 grid points was generated using GAMBIT 2.4 software and the computations were carried out using the CFD commercial code FLUENT…

  • Schematic Principles Of The Principle Of Electro Chemical Machining

    Fig. 1.1 Schematic principle of Electro Chemical Machining (ECM) 1.2 Principle of ECM Electrochemical machining removes material from the work piece by electrochemical process. The working principle is anodic dissolution in which the work piece as anode and the tool as cathode. Both electrodes are immersed in the electrolyte and electrical applied to these electrodes. The electric conduction is achieved through the movements of ions between the anode and cathode through the electrolyte. The…

  • Solid Solubility Lab Report

    Solid solubility is whether that solid can dissolve in specific solvent or not. When a solid dissolve, the ions that comprise the solid will disperse in the solvent thus create a different concentration distribution within the solvent solution. Thus we can view this as a flow of ion from high concentration to low concentration (there’s a flow of ions) Electrical activity is the ability for electron to travel within the material. Specific solid material molecule will have free electrons to…

  • Ionic Bonding Essay

    therefore producing a mobile electron cloud. Valence electrons are that can participate in a bonding. Crystals are held by electrostatic attraction between the negative and positive ions. The loose movement of electrons is responsible for thermal and electrical conductivity. As they carry charges from place to place. As metallic bond are very strong, considerable energy is required to break it. This accounts for the high melting points of metals. Below is shown a picture of free electrons in a…

  • Multiferroic Composite Of BFO Lab Report

    Multiferroic composite of 0.2 LNMFO + 0.8 BFO with LNMFO as ferrimagnetic and BFO as ferroelectric phase were prepared by the standard solid state reaction method. To prepare BFO stoichiometric amounts of high purity Bi2O3, and Fe2O3 were weighed and mixed thoroughly in acetone media for 5–6 h. The mixed powder of BFO was calcined at 800 °C in a closed alumina crucible for 4 h and then pre-sintered at 850°C for 4 h. High purity Li2CO3, NiO, MnCO3 and Fe2O3 were mixed in stoichiometric amounts to…

  • Maxwell's Characteristics: The Basic Laws Of Hydrodynamics

    FREQUENT ENOUGH THAT THE PARTICLE DISTRIBUTION FUNCTION IS MAXWELLIAN. 1.3 THE IDEAL MHD An ideal conducting fluid is one with infinite conductivity σ, or zero electrical resistivity η, and zero viscosity coefficients µ and ξ.In the ideal MHD approximation we regard the fluid as a perfect electrical conductor.Ideal MHD assumes no resistivity, viscosity, thermal conduction, or radiative cooling.This is a highly idealized situation, not attainable in nature; it is called ideal MHD. However, it…

  • Essay On Electrical Heating Of A Pipe

    wet the pipe surface. Electric current is passed along the pipe for preheating (Bird, Stewart, & Lightfoot, 2002). The situation under study is about the electrical heating of a pipe with the assumptions that over a temperature range, electrical conductivity, ke (ohm-1cm-1), is constant, and that the local rate of electrical heat production, Se (E/cm3), is uniform throughout the pipe wall. Heat losses through the pipe are assumed…
