Carbon nanotube 1 Carbon nanotube Carbon nanotubes (CNTs) are allotropes of carbon with a cylindrical nanostructure. Nanotubes have been constructed with [1] length-to-diameter ratio of up to 132‚000‚000:1‚ significantly larger than for any other material. These cylindrical carbon molecules have unusual properties‚ which are valuable for nanotechnology‚ electronics‚ optics and other fields of materials science and technology. In particular‚ owing to their extraordinary thermal conductivity

Recently a scientist by the name of Mark Post helped create a “test tube” beef burger. The burger was grown in a solution of nutrients and cost about 330‚000 dollars to make. The burger was created by taking muscle cells from a cow and growing them into tissue. The meat had to be dyed to make it look like real beef. The meat contains no fat and is disease free. The meat was made in the Netherlands at Maastricht University. It was served to two volunteers and was flavored with egg powder and bread

Research has shown that Manta Rays and Devil Rays are cousins but are different types of marine life. Although they are cousins‚ they are different. They have different body types‚ different habitats and different intelligence levels. If you ever see a manta ray or a devil ray‚ they look very similar. It may not look like they have different bodies but they do. A manta ray can grow to a size of 7m (23ft) and weigh up to 3‚600 pounds. It has 18 rows of teeth on their lower jaw. Their eyes are on

Next we added mossy zinc to the first test tubes‚ Sn granules to the second and Cu filings to the third and compared the rates of evolution of hydrogen gas in each test tube. 2.1.2. We mixed 3mL of 0.02 M KMnO4 and 2mL of 3 M H2SO4 in a test tube and stirred using a glass rod. Next‚ we divided the solution into two. We added 2mL of 0.03 M Na2C2O4 solution to the first half and
