a quartz includes 2 Silicon atoms and 1 Oxygen atom, while the elements that makes up an Iron Phosphate includes 1 Iron atom, 1 Phosphorus atom and 4 Oxygen atoms. The quartz and FePO4 can fit into the same structure is due to the charge of their component atoms. Silicon (Si) has an atomic charge of 4 while Iron (Fe) has an atomic charge of 3 and Phosphorus (P) has an atomic charge of 5. The properties of quartz and FePO4 will be similar in the sense that the 2 atoms in each of the compound (i.e…

In our previous report, 21 we investigated the influence of formulation variables of clotrimazole-loaded cubic liquid crystalline nanoparticles. The composition of chitosan tailored cubic nanoparticles was optimized employing central composite design. The findings of Small angle X-ray scattering analysis confirmed the presence of D and P cubic phases in nanoparticles. Most importantly, considerable improvement in mucin binding was observed upon incorporation of chitosan owing to electrostatic…

Compare and contrast the crystal structures and crystal chemistry of quartz, α-FePO4 and β-FePO4. FePO4 is also known as Iron (III) phosphate. Iron (III) phosphate is an inorganic compound. Most of the FeP04 has the structure of α-quartz which is α-FePO4. It has a tetrahedral molecular geometry. α-FePO4 is present at pretty low degree Celsius. It is also a transition metal as it is in the d-block in the periodic table. It can be studied at many different temperature which range from 294K to…

1005K Another observation is that there is no significant change on the length between the bonds of the cell and the angle with the increase in temperature. However, it decreases slightly after the 980K transition. It can also be concluded from the ATOMS diagrams that the inverse relation between the tilt angle and the temperature. As the temperature reaches the transition temperature, the tilt angle decreases firmly. One may notice that there is no apparent change in the first few stages. Only…

cm-1 relating to the bending band of (HOH) peaks in 2910 cm-1 and 2940 cm-1 related to the stretching bands of (CH2) and Peaks at 1710 cm-1 and 1573 cm-1 are related to the carbonyl group. Also, the peak in 1142 cm-1 indicating the presence of oxygen atoms, the band at 1097 cm-1 is assigned to (C-O) stretching vibration of the ether group and peaks at 851 cm-1 and 607 cm-1 represent stretching vibrations (C-C), which is correspond with reports of other researchers [ ]. It also can be seen in…

In the paper, FePO4 was studied in through neutron powder diffraction across a wide range of temperatures, and was found to have 2 states in general, the α (alpha) phase and β ( beta ) phase. The alpha phase exhibits a tetrahedral structure, which is similar to alpha quartz, and this occurs during generally low temperatures. In the case of this paper, the temperatures experimented on were between 294K and 1073K. The beta phase, however, is denser and exhibits a octahedral structure. The…

In Fig 4 pore size distribution profiles of the Y and MY is observed. By the BJH method, which uses desorption branch of the nitrogen isotherm in order to calculate the pore size distribution and the adsorbed volume[12], the pore size in the range of only 1.4 nm could be seen in Fig. 4a. Presence of various distribution of pore size is the manifest of the related BJH of the MY zeolite in Fig. 4b. As can be seen there are the pore size distributions from 1.2-6 nm in which the pores in the range…

The FTIR spectrum of PVA/CS nanofiber was shown in Fig. 1(a). The band at 3255.32 cm−1 was corresponded to -OH stretching and the peaks at 1025.6 and 1450.04 cm−1 for the -C-O band. The peaks at 3445.32 cm-1, 2965 cm-1, 1640.01cm-1, 1598.7 cm-1, and 1361 cm-1 are due to amine NH symmetric vibration, C-H vibration, deformation vibration of the absorbed water molecules, stretching vibration of amino group of chitosan and vibration of C-H, respectively. The peaks at 890.1 and 1100 cm-1 was…

reduce chemistry to physics. Microorganisms contain cells, which contain molecules and atoms. Atoms are the fundamentals of physics. Thus, you reduce chemistry to physics. Even with chemical reactions that don’t explicitly involve microorganisms, chemistry is still reducible to physics. Chemistry studies interactions that occur when a form of energy is applied to one or more elements. Elements themselves are made of atoms/matter, and heat is a manipulation of energy. Thus, it follows that the…

Saltwater Circuit; Did you know that you can use salt water to make a light bulb shine? It sounds crazy, but it's true! This is because salt water is a good conductor of electricity. Salt molecules are made of sodium ions and chlorine ions. (An ion is an atom that has an electrical charge because it has either gained or lost an electron.) When you put salt in water, the water molecules pull the sodium and chlorine ions apart so they are floating freely. These ions are what carry electricity…
