    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…

    One of the earliest metals to be discovered, lead has a long history with mankind. It was first discovered around 7000 BC as a byproduct of silver smelting. Lead is metal known for its resistance against corrosion, malleability, and low melting point. Mined all across the world, lead was one of the most important metals in ancient times. Although lead was toxic, it was used widely, particularly in the Roman Empire. Through its uses and toxicity, lead affected the classical era in a drastic way.…

    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…

    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…

    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…
