  What is nanomaterial???? A material having. particles or constituents of nanoscale dimensions or one that is produced by nanotechnology.
• 3.
  Nanomaterial Composition • Comprisedof many different elements such as carbons and metals • Combinations of elements can make up nanomaterial grains such as titanium carbide and zinc sulfide • Allows construction of new materials such as C60 (Bucky Balls or fullerenes) and nanotubes
• 4.
  LIST OF APPLICATIONS •Next-Generation Computer Chips • Phosphors for High-Definition TV • Low-Cost Flat-Panel Displays • Tougher and Harder Cutting Tools • Elimination of Pollutants • Longer-Lasting Medical Implants • High-Sensitivity Sensors
• 5.
  • Since nanomaterialspossess unique, beneficial chemical, physical, and mechanical properties, they can be used for a wide variety of applications. These applications include, but are not limited
• 6.
  Next-generation computer chips Ultra-high puritymaterials, enhanced thermal conductivity and longer lasting nanocrystalline materials Improved HDTV and LCD monitors Nanocrystalline selenide, zinc sulfide, cadmium sulfide, and lead telluride to replace current phosphors Cheaper and more durable.
• 7.
  Elimination of Pollutants –Engineeredto be chemically reactive to carbon monoxide and nitrous oxide –More efficient pollution controls and cleanup
• 8.
  TOUGHER AND HARDERCUTTING TOOLS – Tungsten carbide, tantalum carbide, and titanium carbide – Much more wear-resistant and corrosion-resistant than conventional materials – Reduces time needed to manufacture parts, cheaper manufacturing
• 9.
  LONG LASTING MEDICAL IMPLANTS •Higher quality medical implants – Current micro-scale implants aren’t porous enough for tissue to penetrate and adapt to – Nano-scale materials not only enhance durability and strength of implants but also allow tissue cells to adapt more readily

  CONCLUSION • From theabove examples, it is quite evident that nanocrystalline materials, synthesised by the sol-gel technique, can be used in a wide variety of new, unique and existing applications. It is also very evident that nanomaterials outperform their conventional counterparts because of their superior chemical, physical, and mechanical properties and of their exceptional formability.
