Modern engg. materials

  1. 1. Silicon nitride rocket thruster. Left: Mounted in test stand.Right: Being tested with H2/O2 propellantsSilicon carbide is used for Zirconium dioxide is used ininner plates of ballistic vests manufacture of ceramic knife
  2. 2. Concrete is a mixture of cement and Plywood is usedaggregate,strong material that is very widely widely inused construction
  3. 3. [ Schematic of a bilayer OLED: 1. Cathode (−), 2. Emissive Layer, 3. Emission of radiation, 4. Conductive Layer, 5. Anode (+)
  4. 4. Hip Bonereplacement replacementjoints made made fromfrom pureacetabular titanium(ceramic metal platematerial) andwith titaniummetal andcobaltchromiumchemical toenhance bonegrowth
  5. 5. SEM image of 15nm Ni
  6. 6. Nano-Cadmium selenide which glows in UV-region is injected into patientsbody, localize the cancer cells and visible more clear than other bio-dye
  7. 7. • Cathode:Carbon Nanotube(CNT)• Anode: Lithiummetal (Li+)• Electrolyte: Allelectrolytes (incl.bio electrolyteslike blood, sweat,moisture)• Separator:Paper (Cellulose)
  8. 8. Pure carbon is less toxic but continuous intake causes several biological disorder especially lungWorker at carbon black plant in Sunray, diseasesTexas
