An Outline Of An Investigation

It is with out a doubt that in our country the United States of America the lower and middle class have the common perception that the government and the “super rich” have some kind of unknown agreement to maintain extremely lower tax rates on the “super rich”. What do the “super rich” do with all the saved money coming from the tax cut is another unknown, perhaps some luxurious new home, car, or maybe put it to work and continue getting richer. While all this may be true to some degree, one of the “super rich” elite members has stepped fourth not only once but a few time but none compare to his current attempt to make change.

Mineralogical composition for the bulk samples powder were determined using X-ray diffraction (Philips X-ray diffraction equipment model PW/171) with monochromator, Cu k -á radiation (1.542 =גÅ) at 40 kV and 35 mA at X-ray diffraction lab, Physics Department, Assiut Faculty of Science, Egypt. The patterns were recorded from 4 to 90°2è. In addition, reflection peaks were between 4 and 902Ѳ, of 0.06◦/min speed. Corresponding spacing (d,Å) and the relative intensities (I/I°) were also obtained [Moore and Reynolds,1997].

The β phase has an increased degree of dynamic instability due to high value of the chemical bond length. Since tilt angle δ is utilised for FePO4 as both the seperate average tilt angles for FeO4 and PO4, they rely on the fractional atomic coordinates of the oxygen isotopes in the structure. At temperature of 294K, the α-phase quartz form has a polyhedral lattice structure. The high symmetry configuration correlates to the structure that changes with time and that the bond lengths recorded at actual instances is higher than the average values. This is due to tetrahedral tiliting that exists in the quartz structure because of the partially full d-orbitals which gives rise to a large compound. Most importantly, due to tetrahedral tilting, the same relation of symmetry cannot be observed and the properties of α-β isotopes of FePO4 are not indicative or similar in relation to the other polymorphs in this

Phosphorus, symbolized by “P”, is a group five element of the Nitrogen family. Phosphorus has the atomic number 15, means that it has 15 protons and 15 electrons. The name “phosphorus” is resultant of the Greek word “phosphoros”, meaning light bearing. With regard to location and classification, Phosphorus is a non-metal located in the “p” block of the periodic table, found in the third period and the 15th group. Concerning its properties, Phosphorus is a solid at room temperature and can be found in several forms, most commonly as white phosphorus or red phosphorus however, as a result of its high reactivity, phosphorus is never found exclusively. As Phosphorus is a non-metal, it follows the trend of most non-metals whereby it is dull in appearance,

TiO2 occurs naturally in three crystalline structures: rutile (tetragonal), anatase (tetragonal), and brokite (orthorhombic). Rutile is the most common and stable form of this mineral. ZnO exhibts two main crystalline forms: wurtzite (hexagonal)

Phosphates PO4-3 are formed from this element. Phosphates exist in three forms: orthophosphate, metaphosphate (or polyphosphate) and organically bound phosphate each compound contains phosphorous in a different chemical arrangement. These forms of phosphate occur in living and decaying plant and animal remains, as free ions or weakly chemically bounded in aqueous systems, chemically bonded to sediments and soils, or as mineralized compounds in soil, rocks, and

In a nation where over two-thirds of adults are overweight and over one-third are obese, many Americans turn to commercial diet and weight loss programs in an attempt to shed the extra pounds and incorporate a healthy lifestyle (National Institute of Diabetes and Kidney Diseases, 2011). According to Gardner, Kiazand, Alhassan, Kim, Stafford, Balise, Kraemer, and King, (2007) the health benefits of weight loss, have been well established. However, the debate regarding the effectiveness of low-fat, high-carbohydrate diets versus low-carbohydrate diets continues and very limited evidence is available to evaluate other diets (Gardner, et. al 2007).

In this practical the aim for this experiment was to find out the catalytic power of alkaline phosphate, as well as the rate of reaction and the activation energy of p-nitrophenol phosphate.

Summary: X-ray crystallography is a form of x-ray diffraction using crystalline structures. First, a crystal structure is grown that possesses the molecule being studied. The structure is grown most often using vapor diffusion to grow the correct size and shape molecule. Wavelengths are passed through, and then thoroughly analyzed to create a picture that reflects the molecule. Many atoms are too small to pinpoint, so at the end of the process a two dimensional picture is generated, and then transformed into a three dimensional model for each atom.

In this paragraph, we will be comparing between the crystal chemistry of the α- and β- FePO4,

The as-prepared pristine ZnO:P and ZnO:In3+ samples were characterized via X-ray diffraction (XRD) using Cu-Kα radiation (λ= 1.54056 Å) in the 2θ range of 20°-80° [Bruker Advanced-D8 powder X-ray diffractometer]. The scanning speed and steps were 2°/ minute and 0.02° of 2θ respectively. The XRD data were analyzed by Rietveld refinement technique using FULLPROF program to confirm the phase formation as well as to obtain the lattice parameters, space group and crystal system [2]. The microstructures and crystal structures of the nanoparticles were obtained using Transmission Electron

The structure of the prepared material was investigated employing many techniques such as X-rays diffraction, SEM and TEM electron microscopy. In order to scrutinize the crystal structure of the samples X-rays diffraction was carried out using diffractometer XPERT-MPDUG, Philips PW3040. Figure (1) depicts the X-ray diffraction of the as synthesized samples. It can be seen that the nature of the sample is formed in poly crystalline form. The most important peaks are displayed. The most intense peaks were indexed to be 201, 011, 111, 400, 311, 102, 020, and 112. The indexed peaks correspond to single pure orthorhombic phase according to ICDD card 83-1758 (75-2115). The reflection planes, regarding the ICDD card, are

the lattice mismatch of BZO with YBCO. In other words, a certain minimum level of misfit strain provides the necessary driving force for self-assembly to occur. We have recently found that lattice mismatches in the range of 5–12 % generates adequate misfit strains required for the self-assembly[6]. The experimental and simulation results showed that lattice mismatches below this range do not result in enough misfit strains and hence no

Since, for the past three decades, one could see that there are lot of developments in science and technology- especially, in the fields of electronics, fibre-optic communication and lasers [12]. The scientific community achieving this development in functional materials through the single crystals of Si, Ge and GaAs with NLO properties [13]. To enable a material to be potentially useful for NLO applications the material should be available in bulk Tetrafluoro Phthalate crystals (TFP). Also research into the growth of large single crystals TFP of from aqueous solution is currently serving as the important avenue to general progress in understanding many fundamental concepts of crystallization [14]. The effect of seed of different orientations on the habit of c and the change of morphology while doping with dyes have been investigated [15].
