Carbon

Carbon. Carbonat de Calciu CaCO 3 proprietăţile fizice ale materialelor depind de ordonarea moleculelor. CRETA. = MOALE. (molecule de CaCO 3 aliniate întâmplător ). MARMURA. = MAI TARE. (molecule de CaCO 3 mai bine ordonate). COCHILIE. =TARE & FRUMOASĂ.

  1. Carbon

  2. Carbonat de Calciu CaCO3 proprietăţile fizice ale materialelor depind de ordonarea moleculelor CRETA = MOALE (molecule de CaCO3 aliniate întâmplător ) MARMURA = MAI TARE (molecule de CaCO3 mai bine ordonate) COCHILIE =TARE & FRUMOASĂ (molecule de CaCO3 bine ordonate)

  3. CARBON (C) = MOALE COCS GRAFIT = TARE DIAMANT = EXTREM DE TARE ŞI DURABIL

  4. Duritatea este măsurată pe scara lui Moch de la 1 la10. Prin scrijeire eementul mai dur poate lăsa urme pe cel mai moale.

  5. Fullerene C60 1985 Robert F. Curl, Harold W. Kroto and Richard E. Smalley Premiul Nobel pt. chimie1996 Nanotuburi de carbon 1991 Sumio Iijima

  6. 0

  7. How does a carbon Nanotube switch work?

  8. 0 Carbon Nanotubes “Understanding Nanotechnology” Scientific American, Warner Books.Drexler www.imm.org

  9. 0 Electronic Bandgap is determined by the Diameter of the tube. Why is diamond transparent and Graphite black/grey? Think of the way the atoms are Arranged- this changes the Bandgap of the material. Don’t forget the NANOTUBES and BUCKYBALLS !!

  10. Space Elevator climber

  11. NANOTUBE AS HYDROGEN GAS STORAGE Low molecular attraction : almost free movement : high kinetic energy : storage problem H2 molecule WALL OF NANOTUBE H2 molecule

  12. NANOTUBE AS BIOSENSOR Foreign molecule Change of electrical property Nanotube (Electrical property)

  13. FUTURE APPLICATIONS AS DRUG DELIVERY SYSTEM NANOTUBE FULLERENE = CARRIER (DELIVERY SYSTEM) GUIDING DEVICE (REMOTE CONTROLLED) WAR-HEAD (DRUG MOLECULE)
