Nanotechnology
Nanotechnology:
Nanotechnology is the process of modifying matter at a scale close to the atomic level
to create novel structures, materials, and gadgets
...
Engineered systems, gadgets, and structures are referred
to as nanotechnology
...
At this scale, materials start to show distinctive characteristics that
influence their behaviour in terms of physics, chemistry, and biology
...
Poorly soluble nanoparticles are more hazardous than bigger particles on a mass for
mass basis, according to studies
...
Some nanoparticles
may be able to travel from the respiratory system to other systems, according to
studies
...
Richard Feynman, a famous physicist, first addressed the ideas that gave rise to
nanotechnology in 1959 in his lecture There's Plenty of Room at the Bottom, where
he described the prospect of synthesis or through direct atom manipulation
...
K
...
Drexler was inspired by
Feynman's ideas
...
He is no longer a party to the convention
...
The development of
nanotechnology in the modern period was sparked by two significant discoveries in
the 1980s
...
In 1989, it was also
effectively used to manipulate individual atoms
...
As the system gets smaller, a number of phenomena become more obvious
...
Heading from macro to nanometer dimensions has no impact on this effect
...
While
compared to macroscopic mechanisms, a number of physical (mechanical, electrical,
optical, etc
...
One illustration is how changing the surface area
to volume ratio can change a material's mechanical, thermal, and catalytic
characteristics
...
The study of
nanomechanics is interested in the mechanical characteristics of nanosystems
...
Materials that have been scaled down to the nanoscale can display different properties
from those that they do at the macroscale, opening up new applications
...
At nanoscales, a substance like gold, which is chemically inert at
larger sizes, can act as a powerful chemical catalyst
...
