new materials
TRANSCRIPT
What are they? New materials are products of new technologies result of the
development of chemistry and applied physics, engineering and materials science.
How are they obtained? Basically, they’re obtained by NANOTECHNOLOGY.
Nanotechnology studies matter from a nanometer level resolution.
GrapheneGraphene is a substance
composed of pure carbon,
with atoms arranged in a regular hexagonal pattern
similar to graphite
SiliceneThe silicene is similar in structure
and chemical and electrical
properties of graphene. But is
predicted to be more stable that it
resists oxidation upon contact with
air rather than other compounds.
Coltan Coltan is a dull black metallic ore from which the elements niobium
and tantalum are extracted.
Coltan is used primarily for the production of tantalum capacitors,
used in many electronic devices. It is also used in high temperature
alloys for air and land based turbines.
Slaves for this new "black gold"
Carbon nanotubes Nanotubes are the strongest materials known, exceeding up to 100
times the steel.
Objectives and aims of the new
materials
Objectives of graphene Graphene This material will cause the electronic displays are thinner
and can be used in windows, eyeglasses, walls and other objects.
