4. A more familiar example may convince you
of the object in imagining the size of nano-
object
The population of India is more
than one billion or approx 125
crores . Each Indian –you or me- is
nano in comparison with the total
population of India.

5. What is nano material ?
• A material having particles or constituents of
nanoscale dimensions.
1nm = 10-9 m

6. Classification
of
nanomaterials
Zero
dimensional
One
dimensional
Two
dimensional
Three
dimensional

8. Why Nanaomaterials ?
• Nanomaterials are expected to be at the heart
of next technological revolution solid-state
electronics, to emerge as new structural
materials.
• Nanostructure based devices taking advantage
of their unique properties (physical,
mechanical, electronic, optical, etc.) are likely
to become ubiquitous.

9. Applications of nanomaterials
• Biomedical Applications
• Photovoltaic Cells
• Sensors
• Computer chips
• Cosmetics
• textile

10. Need to study the nanomaterials under
high pressure
• To better understand the properties of
nanomaterials or to provide alternative
methods for nanostructuration.

11. Effects occur on nanomaterials
under high pressure
Transformation of nano-constitutive elements
Transformation of the interaction between
nano-objects
Modification of interaction between the nano-
objects and the pressure transmitting medium

12. The aim of the research topic
• The study of nanomaterials under high
pressure compression offers new path for the
investigation of fundamental phenomenon and
for the elaboration of new materials with new
or improved properties.
• High pressure can be used to study the effect
of structuration or confinement at the
nanometer scale.

13. Some experimental studies on the high pressure
compression behaviour of nanomaterials
• High pressure Compression behaviour of CNT
by Tang et al.
• High pressure compression behaviour of Ni
was investigated by Poswal et al.
• The study of AlN by Wang et al.
• Olsen et al. studied the high pressure
behaviour of TiO2 .
and so on.

14. Theoretical Research on
nanomaterials under high pressure
• K. Kholiya & J. Chandra studied elastic properties
of nanomaterials under high pressure
• M.Goyal & B.R.K.Gupta analysis of high pressure
on fullerites such as C60,C70, C84 & CNT.
• Alfonso San-Miguel studied the effect of high
pressure on nanomaterials.
• R. Kumar, U.D. Sharma and Munish Kumar
studied the effect of temperature and pressure
on some nanomaterials such as MgO,CuO,Ni,AlN
etc.

15. FUTURE PLAN
• We will present a theoretical model to study
the compression behaviour of nanomaterials
under high pressure through several
experimental studies and also including some
theoretical approach.

16. Model planned for study
• To study high pressure compression behaviour
of nanomaterials we planned a model that
have two input parameters
Bulk modulus
First order derivative of bulk modulus

17. We consider some nanomaterials and study
separately the contribution of pressure on these
materials
• CuO
• TiO2
• Ni
• AlN
• CNT
• CdSe
etc…
