Nanotechnology

Semiconductors are unique materials; whose electrical conductivity can be changed deliberately, usually in a dynamic [reversible] fashion. They are used to make semiconductor devices, which led to the information Age of the late 20th century.

Nanotechnology deals with structures and materials at the nanoscale, which is on the order of 1 to 100 nanometers. Atoms are the basic building blocks of matter and are typically less than a fraction of a nanometer in size. Nanotechnology manipulates atoms and molecules to create materials and devices with novel properties and functionalities.

Nano technology has its origins in the properties of Atoms, or Atomic Physics.

One of the first to describe this future technology discipline was Dr. Richard Feynman, of CalTech.

The idea is that Atoms can form specialized materials and structures which can self-assemble and therefore be used in existing applications.

A temperature furnace in nanotechnology is a specialized heating device used to control the temperature during various processes such as annealing, sintering, or synthesis of nanomaterials.

Nanotechnology is the understanding and control of matter at the realm of 1 to 100 nanometers. (For reference, a piece of paper is about 100,000 nanometers thick.) At the nanoscale, matter functions differently from both the individual atomic and macroscopic scales, so some unique properties are available for use in the field. Nanotechnology is a natural end-result of scientific development and our ability to understand and manipulate matter at smaller and smaller levels. Just as computers have gone from bulky, room-filling monstrosities to handheld computers, such reductions in size will continue until we reach fundamental physical limits. Quantum mechanics or quantum physics are just the study of subatomic sized objects.

Chemistry plays a critical role in nanotechnology by providing a foundation for understanding the interaction of nanoparticles with different materials, as well as designing and synthesizing new nanomaterials with specific properties for various applications.

Chemistry also enables the development of innovative nanoscale devices and systems that have the potential to revolutionize fields such as electronics, medicine, and energy.

If there were self replicating machines that could coat earth's surface with light reflecting material, this could help reduce earth's temperature. Better still would be self replicating machines that somehow sequestered gigatons of atmospheric carbon dioxide.

About 50 million years ago there was a freshwater arctic fern known as Azolla. It grew on the surface, but when it died it sank into the cold water, where it was covered and preserved. Over hundreds of thousands of years this fern pulled billions of tons of CO2 out of the atmosphere, causing earth to cool, and ultimately resulting in a long series of ice ages. One could view Azolla as nanotechnology--a self replicating machine. But its growth rate would probably be too slow to be of much service to us.

Nanotechnology can be used in science to create new materials with unique properties, such as improved strength or conductivity. It can also be used in medicine for targeted drug delivery or imaging at the cellular level. In environmental science, nanotechnology can help develop more efficient filtration systems or sensors for detecting pollutants.

Some potential disadvantages of using nanotechnology in dentistry include concerns about nanoparticle toxicity, limited research on long-term effects, and the high cost of implementing nanotechnology-based treatments.

There are many reasons for nanotechnology. Imagine machinery that can repair itself. Imagine building ceramic engines from a solution, without fissures or hairline cracks. Just single solid light weight high temperature engines built up like single crystals. Imagine reducing the cost of manufacturing processes by a factor of a hundred. Nanotechnology holds out significant promise for development in numerous areas. Tiny self replicating machines could mine industrial waste for ore, or aid with the clean up of pollution. Imagine armies of tiny self replicating machines sorting garbage, separating metals, glasses, and plastics, distilling alcohol for fuel from waste biomass, and so on. This field remains in its infancy, but as time goes on we will continue to develop interesting techniques and technologies.

Nanoscience is the study of phenomena at the nanoscale, focusing on the behavior and properties of materials at the atomic and molecular level. Nanotechnology, on the other hand, involves the application of scientific knowledge to manipulate matter at the nanoscale to create new materials, devices, and systems with novel properties and functions. In essence, nanoscience is the study of small-scale phenomena, while nanotechnology is the engineering and application of nanoscale materials.

Nanotechnology as a concept has been around since the 1950s, when physicist Richard Feynman first discussed the possibility of manipulating materials at the atomic and molecular scale. However, it began to gain significant attention and develop as a field of study in the 1980s and 1990s.
