This presentation provides an overview of graphene, including its definition, history, current applications, and future potential. Graphene is a single layer of carbon atoms arranged in a honeycomb lattice. It was first isolated in 2004 and has unique mechanical and electrical properties. Current research is focused on integrating graphene into various applications like batteries, solar cells, and water filters. Graphene is seen as an important material for the future due to its strength, flexibility, and ability to conduct electricity and store energy efficiently.

6. Introduction
 The building block of graphite is known as
Graphene.
It is a one-atom-thick layer of carbon atoms
arranged in a hexagonal lattice.
Graphene is a remarkable substance on its own -
with a multitude of astonishing properties.

It owns the title “wonder material”
It was introduced in 1986 by chemists Hanns-Peter
Boehm, Ralph Setton and Eberhard Stumpp.
 It is a combination of the word graphite and the suffix -ene,
referring to polycyclic aromatic hydrocarbons.

8. Invention of Graphene
Single-layer Graphene was explored theoretically
by P. R. Wallace in 1947.
It was first unambiguously produced and identified
in 2004, by the group of Andre Geim and Konstantin
Novoselov
For inventing this super material they got Nobel
prize on 2010
Using the graphite powder in pencil and a scotch
tape they made this Graphene

9. Stage of Graphene
now
Most of the Graphene produced today is used
for R&D in Universities and companies
Some Graphene based products are entering the
market, but mass production of Graphene
hasn't been achieved yet.

10. Graphene is an extremely diverse material, and
can be combined with other elements
(including gases and metals) to produce
different materials with various superior
properties.
Researchers all over the world continue to
constantly investigate and patent Graphene to
learn its various properties and possible
applications

12. future material
It is a better conductor than copper. So the usage of copper is
reduced in future
It stores more energy inside them, so in future solar vehicles
and rapid recharging batteries may be made by scientist
By using Graphene made filters we can easily filter the salts
and other elements in sea water and normal waters
By the usage of Graphene solar panels we can store more
energy than our normal solar panels without using any
batteries.
And more combination of new elements were made using this
Graphene.

13. Graphene in thermodynamics
 The 21st century has brought a lot of new results
related to Graphene.
 Apparently, Graphene has been characterized from all
points of view except surface science and,
especially, surface thermodynamics.
 This report aims to close this gap.
 Since Graphene is the first real two-dimensional solid,
a general formulation of the thermodynamics of two-
dimensional solid bodies is given.

14. Applications of Graphene
It include lightweight, thin, flexible, yet incredibly lightweight
to, electric/photonics circuits, solar cells, and various medical,
chemical and industrial processes.
Hong and his team in South Korea pioneered the synthesis of
large-scale Graphene films using chemical vapour
deposition (CVD) on thin nickel layers.

 It has been used as a reinforcing agent to improve the
mechanical properties of biodegradable polymeric
nanocomposites for engineering bone tissue applications.
Graphene is reported to have enhanced PCR by increasing
the yield of DNA product.

17. Pros of Graphene
It is ultralight and also immensely tough.
 It is two hundred times stronger compare to steel and incredibly
flexible.
 It is thinnest material possible and it is completely transparent
which can transmit more than 90 % of the light.
 It is ultimate conductor and it can function as perfect barrier. The
helium can not even pass through the Graphene.
It can transfer electrons at much faster rate compare to silicon.
It can pass at the speed of 1000 Kms/sec which is about 30 times
fast compare to silicon. 8/17/2018

18. cons of Graphene
Even this material having more advantages it has some
dis-advantages too
Creation of high quality Graphene is expensive and
complex process.
In order to grow Graphene, toxic chemicals are being
used at high temperatures. Due to this it exhibits toxic
qualities.
 It is susceptive to oxidative atmosphere.
