3. RESULTS AND DISCUSSION 3.1. Powder X-Ray diffraction analysis The grown Cd doped LSMH crystal were subjected to powder X-ray diffraction studies using a Rich Seifert X-ray diffractometer employing CuKα (1.54058 Å) radiation‚ scanning angle ranging from 10° to 70° at a scan rate 1°/min to confirm the crystalline phase of the grown crystal. Fig 2 shows the X-ray powder diffraction patterns of pure as well as Cd doped LSMH single crystals. The obtained (h k l) values are indexed using the JCPDS

Investigating the Ratio Between Poly-Vinyl Alcohol and Sodium Borate to form a Bouncing Ball Timothy English Gen. Chem. 1 Lab Section: 009 Introduction: Poly-Vinyl Alcohol (PVA) is a water-soluble synthetic polymer that will be used as one element to form the well know bouncing ball‚ along with Sodium Borate (borax)‚ which has a variety of uses because of its weak base. PVA is ideal for this experiment because it is odorless‚ nontoxic‚ has high tensile strength and flexibility. The

Honors 1-18-12 Relative Solubility of Transition Elements Introduction: In this lab we evaluate the solubility of compounds of iron‚ copper‚ zinc‚ and mercury in both water and acid. Coming into the lab we know that iron‚ copper‚ and zinc are all found in the the same row of the periodic table‚ while zinc and mercury are found in the same column. The transition metals are found in groups 3 to 12 and periods 4 to 6. Rows are known as periods and columns are known as groups. They share characteristics
