3.4. Friction Characteristics of the NCD, MCD and boron doped NCD Coatings against Alumina Balls The friction coefficient curves of NCD, MCD and boron-doped diamond films sliding with Al2O3 balls are shown in figure 4, figure 5 and figure 6, respectively, for a sliding speed of 8 m/s and a load of 1N, 5N and 10N, respectively. Figure 4 (a), figure 5 (a) and figure 6 (a) show the friction coefficient of NCD, MCD and BDNCD at 1 N, respectively. Figure 4 (b), figure 5 (b) and figure 6 (b) show…

Granite is widely known as the hardest building stone in the world. So, just why is this reliable material so strong? Today, the stone countertop experts at Rocky Mountain Granite & Marble in Webster, NY, explain what you need to know: A Sturdy Composition Granite is created when molten rock solidifies under the earth’s crust. Composed of Quartz, Mica, Feldspar, and other strong minerals, it’s only natural the product is so sturdy. In fact, quartz and feldspar are tougher than steel. The only…

phosphoric acid would catalyze the reaction and water would be added to decompose the remaining acetic anhydride. Through the process of filtration, aspirin crystals were collected and separate from the liquid acetic acid-water solution. Lastly, the product was weighed and tested for purity. The experimented resulted in the production 3.68 g of aspirin crystals which had a little impurity. This report discusses an experiment to study the synthesis of a drug from organic material. The experiment…

I. Diamonds are crystals made of a chemical called carbon. They are the hardest known natural material in the world, and one of the most valuable. In the Greek language, the word diamond means indestructible. It is possible to create diamonds with carbon and by applying extreme heat and pressure. Diamonds are measured in carats; one carat is two-hundred milligrams. Diamonds are better conductors then any other metal in the world, four times better than copper. Time, money, and extreme heat and…

minimum amount of boiling hot solvent, filtering insoluble impurities while the solution is hot; crystallizing the purified compound, and isolate the pure compound by vacuum filtration . The unknown used in the experiment was #4, which were white crystals. In order to determine the ideal solvent we prepared two test tubes. Test tube #1 containing 0.106g of unknown and 3mL of water, it was well mixed. At room temperature water dissolved a small amount of the solute while boiling hot it was…

rack and then 2 minutes in an ice-bath to allow for complete crystallization. The crystals were then put through the filtering apparatus to collect and dry all the crystals. About 3ml was used to rinse the crystals while in the apparatus. The crystals were then dried and the yield and melting point were taken. Results • Maleic anhydride = 0.4g (0.004 moles) • Ethyl acetate = 1ml • Hexane = 2ml + some to rinse crystals • Cyclopentadiene = 0.4ml (0.0048 moles) • Filter paper before = 0.18g…

Crystals form when a type of liquid cools down, and then hardens. The process when crystals grow is called "nucleation". Whenever a person eats salt, they are eating salt crystals. These crystals are called salt crystals. To make homemade salt crystals, the materials you need are hot water and salt. When dissolving salt in water, the salt is not changing its properties. This project will use different types of waters to see how many more crystals it will help grow. Dasani water is a brand of…

structure with space group P6422 (group no. 181), in which iron, phosphate and oxygen occupy Wyckoff position 3d, 3c and 12k respectively. 2. Crystal chemistry and…

them at their best. One of the main problems faced with freezing is a change in texture. When frozen water expands and can cause tissue damage. When the food is thawed it will be mushy and soft because of the tissue damage. When frozen slowly larger crystals will appear and cause more tissue damage. When frozen quickly the ice…

Lab Report: Density and Viscosity Problem: What is the effect of density on the viscosity of a substance? Hypothesis: Density will affect the viscosity of a liquid. The order of the liquids from most dense to least dense is: syrup, detergent, water, oil Background: Density and viscosity are closey related in which they both affect one and other. Denisty has many factors like weight, mass, and volume. To work cohesivly there are different things we must pay attention to. Density is how closley…
