1.2.2. Physical Properties Methyl ethyl ketone is a clear, colourless fluid that is less viscous than water and has a somewhat acute odor that smells most of the ketones and is described by some as being similar to Boerscot. Compared with acetone it is less volatile and less soluble in water (about 27.5g / 100mL at room temperature). It is a solvent used for extracting gums and oils from plants and cleaning the remnants of metal and glass, so why often a cleaner or ingredient is found 1.2.3.…

Capacitance properties of electrodeposited polyaniline films on stainless steel substrate. A.A. Al-Owais1,I. S. El-Hallag2, M.A. Ghanem3 1,3Chemistry Department, Faculty of Science, King Saud University, Riyadh ,SA 2Chemistry Department, Faculty of Science, Tanta University, Tanta, 31527, Egypt Abstract. Polyaniline (PANI) thin films were successfully synthesized from a mixed solution of 1M aniline and two different concentration solutions of H2SO4 on a stainless steel substrate. The…

Chemical Engineering From all of the engineering fields, I decided to pursue a chemical engineering degree because of its ample area of study. Chemical engineers not only work evaluating and optimizing chemical processes, but also they must analyze production costs and develop reports according to the data they obtain (“Occupation”). As soon as I finished high school, I was interested in studying Chemistry; I wanted to research and experiment. Then, it was when I learned about the engineering…

around 50-80% fetal hameolgobin. A 6 month old baby tends to have around 8% of HbF and over 6-months 1-2%[23]. The importance of fetal haemoglobin (HbF) in sufferers is due to its high oxygen affinity, which means it does not participate in the polymerization process (were abnormal hemoglobin become jammed in blood vessels, hindering the flow of blood around the body); in effect still delivers oxygen to cells in the body and does not cause server pain in sufferers [33]. Hydroxyurea, however,…

means that the cells were mobile. In tube #1, the cells regenerated their flagella and in tube #3, the cells were never deflagellated so the addition of colchicine did not have an effect on the flagella. Colchicine affects polymerization of flagella, but in tube #3, polymerization already occurred beforehand. The class data shows similar results to our results. In Tube #2 (experimental group), the number of immobile cells remain constant with very little fluctuations, which is what was expected.…

discovered in 1883, which makes it one of the oldest enzymes ever observed (Kunamneni et al., 2008).Laccases are found in a diversity of fungi, bacteria and higher plant species (Santhanam et al., 2011). These laccases are involved in a degree of polymerization or depolymerization processes. In plants, they are involved in…

deformation in erythrocytes that have HbS [9]. The deformation of erythrocytes clog blood vessels and stop oxygen from moving into tissues where it is essential for organ functions and survival [6]. The inflammation of the body is a response to the polymerization of HbS in erythrocytes. Cation channels open in order to prevent dehydration of erythrocytes and reduced…

ethylene. Depending on the mode of polymerization, three basic types of polyethylene are frequently used: linear High-Density Polyethylene (HDPE), and Linear Low-Density Polyethylene (LLDPE), Low Density Polyethylene (LDPE). HDPE has a low degree of branching and thus greater intermolecular forces…

Describe the Properties of Biopol Biopol is a copolymer made of the monomers PHV and PHB. PHB alone, with its short methyl side chain, is brittle and has very high crystallinity, meaning it cracks easily. Due to its high crystallinity and overall unsuitable properties for industrial use, PHV has been added to created PHBV, or Biopol. Biopol is semicrystalline, meaning it can still crystallize as well as melting at a lower temperature than PHB, making it industrially suitable. Due to its long…
