The Japanese Space Elevator Association YOSHIO
AOKI space elevator extends beyond the earths
atmosphere for 32,000 km, its aim being to
transport astronauts, technicians, tourists and
nuclear waste from the earth to the orbiting
space-station. It is envisaged that there will be
a cable consisting of numerous carbon nanotubes

Targeted nanoparticels for drug delivery to
diseased cells. This method was developed by the
Researchers of the Missouri University, Columbia
(USA).
4
Carbon Nanotubes. They consist of a molecule with
sixty carbon atoms (C60), the fullerene,
discovered in 1986 by Richard Smalley of Rice
University.

NANO-STRUCTURED NATURE a new generation of
water-repellent materials from the leaves. Water
never adheres to lotus leaves, but runs off in
numerous little drops that form, as a result of
the high surface tension on the leaf, and takes
with it the dirt and small insects to be found on
the leaf. This is possible because the lotus
leaves have a layer of hydrophobic-wax globular
crystals 1 nm in diameter. The water-repellent
properties of the lotus-leaf. The hydrophobic
effect on lotus-leaves.

The toes on the feet of a gecko are
nano-structured and equipped with adhesive
lamellae that create a force produced by the
bristles that is equal to about 400 times the
weight of the creature itself. The gecko also
possesses an intelligent adhesive that can modify
the force of adhesion in accordance with the
surface with which it is in contact. Each of the
geckos foot are covered by about half a million
bristles and the end of each bristle is
sub-divided into hundreds of spatulas.

Nano-structured products in building several
nano-structured products are available on the
market from mortar for refurbishing reinforced
concrete to photo-active cements, from
thermo-insulating plaster to protectors for wood.
Self-cleaning surfaces have become a reality,
thanks to the photo-active coating containing
nano-particles of titanium dioxide (TiO2).
Photo-active cements also have a purifying effect
on the atmosphere, which has resulted in these
cements being called smog-eaters the Church
