microstructural behavior (Scanning electron microscopy)‚ Dielectric property (Permittivity analyzer) and crystal lattice vibration (Fourier-Transform Infrared Spectroscopy). In the X-Ray diffraction spectra‚ it is expected to observe the presence of a doublet peak from the reflection of (002) and (200) planes in tetragonal BT and an increase in its diffraction angle due to shorter distance between crystal planes. SEM image of doped BT will show smaller grain size due to substitution of Ca ions

The lab was to include a purpose‚ procedure‚ data/observations‚ all reactions and side reactions written out with qualitative data beneath each product and reactant except H20‚ and a summary. The purpose of this experiment is to observe the qualitative aspects of a series of reactions involving copper. Procedure 1.Measure about 1g of solid copper. 2.Place Cu in Erlenmeyer flask and place flask under fume hood. 3.Add dropwise 15M HNO3 until solid copper is completely reacted. 4.Place flask

DO NOT PLAGIARISE THIS MODEL ANSWER Paragraph 1 ZnS exists in two polymorphs‚ namely sphalerite and wurzite. Analysis of its symmetry and crystal structure using ATOMS will be used to deduce its possible polytypic stacking sequences as well as the orientation relationship between these two structures. Sphalerite is a face centered cubic structure with each sulphur bonded with four zinc atoms

CHAPTER 3: CRYSTAL STRUCTURES & PROPERTIES ISSUES TO ADDRESS... • How do atoms assemble into solid structures? (for now‚ focus on metals) • How does the density of a material depend on its structure? • When do material properties vary with the sample (i.e.‚ part) orientation?

Determination of Reaction Rate Law from the Reaction of Crystal Violet with Sodium Hydroxide ______________________________________________ Abstract: This experiment helps determine the rate of reaction of crystal violet while it reacts with sodium hydroxide with respect to crystal violet. The amount of sodium hydroxide is varied in this experiment while crystal violet is kept at a constant. The transmittance of crystal violet is observed and recorded using a colorimeter and the data obtained is

Abstract-In this we use a piezoelectric crystal which gives variable voltage output depending upon the vibrations given on the crystal surface. This voltage is converted to current using suitable converter. Now the current is passed through a memristor‚ which has a corresponding resistance value. Whenever the current increases‚ the resistance value increases and the change in resistance is detected using a microwave generator connected at the end. Using the microwave level‚ an external device (similar
