ore of tin. With many other names, this oxide of tin is the most important raw material in tin chemistry. This colorless, diamagnetic solid is amphoteric. 1.2 Structure It crystallises with the rutile structure, wherein the tin atoms are six coordinate and the oxygen atoms three coordinate. SnO2 is usually regarded as an oxygen-deficient n-type semiconductor.[4] Hydrous forms of SnO2 have been described in the past as stannic acids, although such materials appear to be hydrated particles…

look at the forms of their crystal structures. Sphalerite has a lattice structure that is cubic 2L (1 1) while wurtzite has a hexagonal 3L (3) ~ lattice system. In the figure below (Figure 1), we have constructed a sphalerite model, created with the ATOMS program. The diagram has been labelled with yellow, green, and…

Fig: Schematic representation of LHC and it's detectors The primary objective of LHC is to answer the following questions: 1. Why some particles are heavier than others? If the Higgs mechanism is valid? 2. If the super-symmetry theory is valid? If yes then if super-symmetric particles exist? 3. If the concept of dark matter and dark energy correct? 4. Why our universe is made up of matter only? 5. What was the state of matter in the early universe? 6. What will be the properties…

cylindrical carbon molecules have unusual properties, which are valuable for nanotechnology, electronics, optics and other fields of materials science and technology. Nanotubes are members of fullerene structural family. Nanotube’s walls are formed by one-atom thick sheet of carbon called Graphene. The combination of rolling angle and radius decides the nanotube’s properties. They have extraordinary thermal conductivity, mechanical, and electrical properties. There are two types of CNTs:…

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…
