virgin polycrystalline silicon which are placed in a quartz crucible along with small quantities of elements called dopants - the most common of which are boron‚ phosphorus‚ arsenic and antimony. The materials are heated to a temperature above the melting point of silicon‚ 1420 degrees Celsius. Once the polycrystalline and dopant combination has been liquefied‚ a single silicon crystal‚ the seed‚ is positioned on top of the melt‚ barely touching the surface. The seed has the same crystal orientation

The Empty Pot (China) BY royal proclamation‚ the Emperor of China announced a contest to decide the next heir to the throne. The Emperor was old and had no son‚ and because he had been a plant-lover for years‚ he declared that any boy who wanted to be king should come to the palace to receive one royal seed. Whichever boy could show the best results within six months would win the contest and become the next to wear the crown. You can imagine the excitement! Every

Our Iceberg is Melting is a story of penguins who are very comfortable with their present existence until a curious penguin named Fred discovered one day as result of curiosity that their iceberg was melting. The iceberg was the foundation of the penguins’ existence and without it they would perish. Fred had the courage to inform Alice who is a member of the Leadership Council about condition of the iceberg. Alice was a penguin who got things done and would listen to Fred. Fred had the opportunity

Lab #1: Melting Points of Organic Compounds Report Form May 15‚ 2014 1. A “Melting Point Range” refers to the range of temperature at which a solid melts into its liquid state. 2. Pure compounds have narrow or ‘sharp’ melting point ranges‚ 1°C or less if the compound is very pure. A less pure compound exhibits a broader melting point range‚ between 3°C to 10°C as well as a depressed or lower range. 3. Crushing the sample allows for greater surface area-to-volume ratio of the powder‚ this

Crystallization and Melting Points Organic Chemistry 221 9/19/2012 Intro/Purpose: The purpose of this lab was to use crystallization to separate a compound from a solvent and be able to choose the best solvent to do so. Then identify an unknown and verify purity using melting points. Solubility contributes to crystallization; because a solute has lower solubility at lower temperatures‚ which makes the solvent separate from the solution as a solid. This process is important to understand because

Chicken Pot Pie Today I am going to teach you how to cook chicken pot pie in a crock pot. This recipe is a family favorite and is especially great in the winter time to come home to a hot cooked meal. This recipe has been in the family for a couple of generations‚ my great great grandmother first made it and it has gone down the generations since then. First‚ you will have to have the ingredients to make chicken pot pie and also a crock pot. The ingredients that you will need to make this include:
