Nanotechnology has been recently subject to increasing attention and this is due to its significant role in science and technology. Taking into account Nanotechnology applications in geoscience especially petroleum geology, mining and environment, studies on these subjects are necessary.
Technical capabilities of nanotechnology:
- Self-assembly products
- Very fast computers (milliard times faster than available computers)
- New innovations and inventions
- Economic and safe space travels
- Medical nanotechnology (decrease of diseases)
- Obtaining higher education
- Restoring extinct species
- Land reclamation
Nanotechnology, A New Revolution In The World
Nanotechnology is controlled in a small world. The goal of nanotechnology is to build things the way nature has been doing it for millions of years: atom by atom, molecule by molecule, with a "bottom up" approach.
"Nano" is a prefix used in the science world to mean "a billionth of," and nanotechnology deals in billionths of meters, the dimensions at which atoms mingle and molecules interact.
The idea is that if humans could tell atoms how to arrange themselves and how to behave, many of the properties of a material could be controlled at will. Just as nature turns the carbon atoms of coal into diamond by changing their arrangement, so can properties such as color, strength and brittleness be determined at the atomic level.
Scientists believe that if they could learn how to make a brick atom by atom, its molecules could also be "instructed" to self-repair when a crack appeared, or to react to humidity in the air by becoming less or more porous.
General applications of Nanotechnology
Nanotechnology is a necessary element to understand nature. …………………………
Some of the applications of nanotechnology are:
- Industrial production
- Medicine and human body
- Resources durability: agriculture, water, energy, materials and clean environment
- Air and space
- National security
Nanotechnology applications in geoscience:
- Oil industry:
Nanofilters would help with oilfield separations, and nonocataysts could have a multibillion-dollar inpact on refining and processing. Buckytubes also have many potential IT applications, including electromagnetic interference shielding, flat-panel displays, novel composite materials and high-performance electronics.
Nanotechnology could help improve oil and gas production by making it easier to separate oil and gas in the reservoir—for instance, through improved understanding of processes at the molecular level. There are many other potential clean energy sources that could be enhanced through the use of nanotechnology. The practical application of nanotechnology in the oil sector is, fortunately, less frightening. It opens interesting prospects for improved oil recovery, not least through better understanding of processes at the interface between liquids and solids. The aim is to understand how oil and water can be separated more effectively. Nanotechnology could be applied to improved oil recovery in the form of tailoring surfactants. These can then be added to the reservoir in a more controlled way than with existing substances, thereby releasing more oil. It could also help develop new metering techniques with tiny sensors to provide improved information about the reservoir.
