2. What is nanomaterial ????
A material having.
particles or constituents
of nanoscale dimensions
or one that is produced by
nanotechnology.

3. 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

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 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

6. 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
phosphors
Cheaper and more durable.

7. Elimination of Pollutants
–Engineered to be chemically reactive to
carbon monoxide and nitrous oxide
–More efficient pollution controls and
cleanup

8. 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

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

10. 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.
