A polymer is a large molecule which is formed by repeated linkage of small molecule called monomers. Conducting polymer have been the subjects for many decades as possible synthetic metals. Many of these polymer, especially those with a conjugated pi-bond system ,often yield higher conductivity once having undergone the doping process. Polymers are typically insulators due to their very high resistivity .Insulators have tightly bound electrons so that nearly no electron flow occurs ,and they…

AC 2.3: Explain the method of making titanium alloy and investigate how the composition and structure of metal alloys, polymers and poly-matrix composites influence the properties of the parent material. 1. Extraction process. 2. Melting process. 3. Storage process. Extraction of Titanium by Kroll process: First titanium ore Rutile (TiO2) is taken. Rutile is converted into titanium sponge by the following process: Titanium tetrachloride (TiCl4) – a colourless compound is obtained as a result…

refining slag with specific chemical composition, usually based on calcium oxide. The duration of mixing of the metal with the slag in inert gas, the early formation of refining slag, then optimization of the metal oxidation providing the formation of iron oxide FeO in the slag to be less than 0.5 % able process of desulfurization. Using of rare earth metals for desulphurization of steel is very promising. However, the number of practical and theoretical data on the use of rare earth metals for…

Titanium is a low-density element (has 60% density of steel), that be able to be highly modified by alloying and distortion processing. Titanium is non magnetic, non toxic and has good heat transfer properties. Titanium and its alloys have melting points advanced those of steels, but maximum useful temperatures for structural applications usually range from 425-540C°. Titanium has good resistance to attack by most mineral acids and chlorides [ASM]. The combination of high strength, stiffness,…

4.TAGUCHI ANALYSIS FOR THE EXPERIMENTAL RESULTS To examine the 100Cr6 bearing steel through DCT, and to identify the optimum parameter condition of the DCT process, the prediction of the Taguchi analysis is used. The Taguchi analysis and ANOVA, gives the optimized parameter setting and the most influential factor of the DCT process respectively. The quality performance of the deep cryo-treated 100Cr6 steel samples based on the L9 OA was evaluated by conducting the reciprocatory wear tests.…

talked about personal issues and seemed like she needed someone to talk to. These patients had one thing in common, having no insurance. They were able to receive birth control and a yearly physical at a low cost. They all also shared low levels of iron; this may predict the population coming to this health department is not eating enough nutritious…

The SEM result was also in good agreement of XRD analysis. The average particle size of CuMnRC1, CuMnRC2 and CuMnRC3 catalyst was 0.675µm, 3.127µm and 7.435µm respectively. The particles of CuMnRC1 catalyst was least agglomerated, highly porous, high surface area and uniformly distributed. The choice of different precipitant in the CuMnOx catalysts leads to the change of the surface distribution of Cu, Mn and O elements, which might be related to the CO oxidation catalytic performance of the…

incorrectly labeling the iron content on their products. The purpose of this experiment was to analyze the amount of iron in approximately one serving of Total Whole Grain cereal and in one iron tablet and determine if these accusations were true. The values collected would then be compared to the actual values for these products. Total cereal contains 100% of the recommended daily allowance for iron, and the iron tablet contains 361% of the recommended daily allowance for iron. The actual…

The purpose of this report and lab was to assist in visualizing the structure of infinitesimally small objects and how they fit together. Normal object fit together similarly to microscopic atoms and experiment 2 exploits this to help understand structure property relationships. The knowledge gained here directly applies to the world as applications of the materials becomes apparent as the properties are explored. Copper There are a plethora of modern technological uses of copper. It can be…

their stone and copper predecessors because they could make stronger, longer, and sharper swords. Steel requires large amounts of iron ore, carbon, fast-flowing water, and a long lasting fire. It was created by smelting the iron ore and carbon together in a very hot fire. The Inca didn't have steel because they could not build a long enough lasting fire to heat the iron due to their wet climate. This affected their development because they didn't have strong weapons to take over other…
