Sickle Cell Anemia Sickle cell anemia is an inherited blood disease. The word anemia is defined as meaning that the blood does not have the required number of red blood cells. These cells take on a crescent shape‚ which is where the disease takes its name from the abnormal sickle shapes of the cells. It is commonly found in people from Africa‚ the Mediterranean region‚ southern India and the Middle East. “This disease of the blood was first discovered in 1910 in a black college student from the

precipitate was cloudy and turned dark. Part III: Formation of Copper oxide Observations of Copper (II) hydroxide when heated: Copper (II) hydroxide when heated turned very dark. It turned dark blue and had black specks floating around in the solution. After being heated for a time the aqueous solution turned gray and a black precipitate was formed. Part IV: Formation of copper (II) sulfate Observations of copper (II) oxide when reacted with 6mL of 3 Moles of Sulfuric acid: the black precipitate

Spring Term 2005 Plummer‚ Chapter 10 1 Lecture 12 - Etch and Pattern Transfer I (Wet Etch) Introduction • Etching is selective removal of thin film(s) resulting in a desired thin film(s) pattern • The Etch Mask is usually photo-resist or oxide/nitride • Multi-layer structures can be etched sequentially using same masking layer • Etching can be done in either “wet” or “dry” environment – Wet etching = liquid etchants – Dry etching = gas phase etchants in a plasma.

April Goodson CHEM 242L-002 February 20‚ 2013 Oxidation of Cyclohexanone to Adipic Acid Abstract The cyclic ketone cyclohexanone was oxidized to adipic acid using the oxidizing agent nitric acid. The experiment yielded 0.2667 grams of adipic acid‚ giving a percent yield of 113.97%. Although the product was allowed to dry for one week‚ residual moisture was still present in the sample and a melting point could not be obtained. This error in the experiment either resulted from adding too much
