Introduction of NanotechnologyCreated by Fajar Budi Laksono

Nature hides a lot of mystery

SPIDER WEBThe tensile strength of spider silk is greater than the same weight of steel and has much greater elasticity.Its microstructure is under investigation for potential applications in industry, including bullet-proof vests and artificial tendons.

LOTUS EFFECTSelf-cleaning and superhydrophobicProtection against pathogens like fungi or algae growth, and also for animals like butterflies, dragonflies and other insects not able to cleanse all their body parts.

BUTTERFLY WINGVarious iridescent colors by thin-film interference: similar, analogous structures made of keratin are found in iridescent bird plumage.

Gecko FootGecko toes have special adaptations that allow them to adhere to most surfaces without the use of liquids or surface tension.The setae of a typical mature 70 g (2.5 oz) gecko would be capable of supporting a weight of 133 kg (293 lb)

BONEHigh compressive strength of about 170 MPa (1800 kgf/cm)Lightweight yet strong and hard, and serve multiple functions.NANOTECHNOLOGYDETECTED!!!

Nanotechnology is the manipulation of matter on an atomic, molecular, and supramolecular scale.

National Nanotechnology Initiative, which defines nanotechnology as the manipulation of matter with at least one dimension sized from

1 to 100 nanometers

Quantum Size EffectThis effect does not come into play by going from macro to micro dimensions. However, quantum effects can become significant when the nanometer size range is reached, typically at distances of 100 nanometers or less.

Additionally, a number of physical (mechanical, electrical, optical, etc.) properties change when compared to macroscopic systems.

One example is the increase in surface area to volume ratio altering mechanical, thermal and catalytic properties of materials.ImpactPhotocatalyst, anti-bacterial, super-hydrophobicity, self-cleaning properties, etcWhat can NANOTECHNOLOGY produce??
