What is nanomaterial ????

A material having.

particles or constituents

of nanoscale dimensions

or one that is produced by

nanotechnology.

Nanomaterial Composition

• Comprised of 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

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

• Since nanomaterials possess unique, beneficial chemical, physical, and mechanical properties, they can be used for a wide variety of applications. These applications include, but are not limited

Next-generation computer chips

Ultra-high purity materials, 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 phosphorsCheaper and more durable.

Elimination of Pollutants

– Engineered to be chemically reactive to carbon monoxide and nitrous oxide

–More efficient pollution controls and cleanup

TOUGHER AND HARDER CUTTING 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

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 the above 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.
