Aluminum is used in many of our household items. From pie pans to pop cans, Aluminum is a very common product. Charles M. Hall is an American Chemist who figured out how to produce aluminum using his electrolytic method. This method allowed aluminum to be mass produced. Hall was born on December 6th, 1863 in Thompson, Ohio. His father was a missionary and minister who was very educated. Education played a big part in his childhood. He read numerous science magazines and articles as a child. He…

its physical properties. The iron was separated using a magnet and the salt was removed because it was soluble in water, while the remaining sand was not. The mixture in its tray weighed 51.61 grams. The container weighed 2.51 grams, so the mixture alone weighed 49.10 grams. Running a magnet over the mixture successfully removed the iron. It was determined that the more surface area a mixture was spread over, the more iron was picked up by the magnet. The mass of the iron collected in its tray…

For the past two decades, more research efforts have been focused on the development of Advanced High Strength Steels (AHSS). The AHSS include Dual Phase (DP) steels, [1–10], High Strength Low Alloy steels (HSLA), Transformation Induced Plasticity (TRIP) steels, Twinning Induced Plasticity (TWIP) steels, and medium manganese steels, (Bouaziz et al., 2013). The majority of the research are focused on the development of third generation of steels due to interest in the mechanical properties of…

Sarah Bounab BQD Experiment 2: Copper/Iron Stoichiometry Abstract: The purpose of the Copper/Iron Stoichiometry lab was to determine which of the two possible iron sulfate compounds formed when reacting aqueous copper(II)sulfate with solid iron metal. The techniques used in this lab were weighing by difference, quantitative transfer, and vacuum filtration. At the end of the experiment it was found that iron was the limiting reactant and iron(II)sulfate was a product of the reaction between…

be described using a common sulfide mineral, Pyrite (FeS2). The oxidation of FeS2 breaks down into three components, iron, sulfate, and hydrogen as seen below: FeS_2+7/2 O_2+H_2 O→Fe^(2+)+2SO_4^(2-)+2H^+ 1/2(1) These three dissolved compounds raise the acidity of the water and decrease the pH, unless neutralized. The ferrous iron, provided enough oxygen, will oxidize to ferric iron, which will reduce the pH level and act as an oxidant to additional pyrite.…

Study of Stress Corrosion Cracking (SCC) in Alloys Jiang Jingxing 1. Introduction of Stress Corrosion Cracking Stress Corrosion Cracking (SCC) is the growth of cracks with a under the combined effects of a static stress and a specific chemical environment. All SCC failures involve a macroscopic brittle performance, and the ductility of the material is reduced. It is universally acknowledged that there is no single mechanism for stress corrosion cracking (Ford, 1984). Stress…

Persuasion is a constant and rather successful method of getting people to do certain things. We are constantly being influenced and also influencing other people around us. There are several principles that help explain why humans sometimes irrationally do certain things that they wouldn’t normally do. Three of this several principles include the paradox of choice (which proves that when giving a lot of choice for any particular item, satisfaction decreases and sales decreases), scarcity (which…

To counter the adverse effects of emergency room overcrowding, the author of this paper proposes the implementation of a fast-track program. FTAs are designed to handle urgent conditions that can be treated quickly. Patients that are classified as non-urgent (ESI levels 4 or 5) are seen in a designated area within the emergency department. One could describe the FTA as an express lane to treat those with less serious illnesses or injuries. A study performed in Turkey showed that FTAs lessen…

Other properties are: • Cannot be heat treatment hardened • Able to be hardened to high strength level whilst retaining a good level of ductility and toughness • Depending on composition and work hardening they are generally non magnetic • High hygienic properties in temperature changes Martensitic→ has highest content of carbon of the group (1%) and thus are able to be hardened and tempered resulting in being used high strength (with sacrificial…
