Nanomaterial’s
Definition:
" Nanotechnology " is a generic term that describes applications in many scientific fields but covers general research principles and existing properties at the Nano scale , that is to say at the level of atoms and molecules. The objective is to produce nanotechnology objects or materials below 100 nanometers. These nanomaterial’s are composed of nanoparticles which, unlike the fine natural or derived from combustion particles are produced intentionally. Nanomaterial’s can be metals, ceramics, carbon , polymers or silicates which have the advantage of having specific characteristics compared to the same materials at the macro scale . The acquisition of these new physico- chemical properties and opens a huge field of basic and applied research grouped under the name of “Nano science ".
History:
Brussels, 18 October 2011 - “Nanomaterial’s" are materials whose main constituents have dimensions between 1 and 100 billionths of a meter: this is the content of the Recommendation adopted today by the European Commission. This announcement marks an important step f...
Amandi Hiyare: Before forming my research question, I had a discussion with my research project coordinator “Lisa Pope” who told me that the Flinders nanotechnology research team has been developing microbial catheters. Then on Monday I had an interview with Professor Joe Shapter who told me that your team was leading this project. So I was wondering whether you would be able to provide me with some detailed information about this innovation?

It is clear that nanotechnology has the potential to revolutionize health care and even transport
Nanotechnology is defined as the science of design, synthesis and characterization of matter at the nanoscale, which mesures one billionth of the meter [1,2] On that scale, structures exhibit novel chemical, physical and biological properties and processes, which enables the creation of engineered nanomaterials (ENMs), with various characteristics and potential applications. [3] It’s not just that though. Nanotechnology shows the ability to eliminate the gaps among medicine, material engineering and science, computer technology and public policy, creating new clinical and medical approaches to better diagnose, treat and prevent any kind of illness. In fact, it is already moving from simple passive structures

Nanotechnology is the manipulation of structures at nano levels. It uses incredibly small materials, devices, and systems to manipulate matter. These structures are measured in nanometers, or one billionth of a meter, and can be used by themselves or as part of larg...
Just what is it that makes up nanotechnology? Atoms and molocules are so small they invented new word to describe them, “nano”, which is a greek prefix meaning dwarf. “In 1981, the development of a powerful microscope allowed people to visualize the nanoscale on metals. Called the scanning tunneling microscope (STM), the microscope magnifies images of the shapes of atoms on the metal's surface.” (Nelson) Manufacturers create ultrafine nanoparticles from common compounds like carbon, silver and titanium dioxide. They can change strength, produce a desired color or even create an antibacterial effect.
Nanotechnology, shortened to "nanotech", is the study of the control of matter on an atomic and molecular scale. Nano science and nanotechnology are recent, revolutionary development in Science and Engineering that are evolving at a very fast pace.[1,2] It is driven by the desire to fabricate materials with novel and improved properties that is likely to impact virtually all areas of the physical and chemical sciences, biological sciences and health sciences. The word ‘nano’ derives from the Greek word ‘nanos’, which means dwarf or extremely small and mathematically, a nanometer is a billionth of a meter or 10-9 m. Particles whose sizes fall in the size range of 1-100 nm is called a nano particles, whether it is dispersed in gaseous, liquid or solid medium. Generally nanotechnology deals with structures of the size 100 nanometers or smaller, and involves developing materials or devices within that size. Nanotechnology is very diverse, ranging from extensions of conventional device physics, to completely new approaches based upon molecular self-assembly, to developing new materials wi...
Nanotechnology is defined as “ a technology executed on the scale of less than 100 nanometers, the goal of which is to control individual atoms and molecules, especially to create computer chips and other microscopic devices” (Webster’s Dictionary, 1999). In the early 1970’s an MIT student by the name of K. Eric Drexler came up with the idea of manufacturing things, both biological and non-biological, from the molecular level up. Drexler noticed the amazing talents of natural biology and wondered if humans could mimic biology on a mechanical level,
“Nanotechnology is science, engineering, and technology conducted at a nanoscale which is about 1 to 100 nanometers,” according to the National Nanotechnology Initiative. A nanometer is a billionth of a meter, there are 25,400,000 nanometers in an inch and a sheet of newspaper is about 100,000 nanometers thick. Putting that into perspective, if a marble were a nanometer, a meter would be the size of the Earth. Nanotechnology can be used throughout all fields of science, including chemistry, biology, physics, materials science and engineering to study and apply extremely small things. Physicist Richard Feynman introduced the concepts of nanoscience and nanotechnology with his talk titled “There’s Plenty of Room at the
Though nanotechnology is considered one of the newest forms of technology with the roots starting just 29 years ago in 1985 with the discovery of fullerene, which are molecules composed entirely of carbon in the form of spheres, tubes, and many other shapes. It has had a fast progression because of the endless uses scientists are creating. such as oil companies like BP who could soon be using an innovative new technique involving nanotechnology and magnets to help clean up offshore oil spills from container ships or offshore platforms that are a frequent hazard to marine and coastal ecosystems and an expensive one to clean up. “BP expects the Gulf of Mexico oil spill in 2010 -- the worst environmental disaster in U.S. history -- to cost it $40 billion.” however with this new invention they will use water-repellent nanoparticles that conta...
The main purpose of green nanotechnology has been to develop clean technologies that would minimize potential human and environmental health risk. Also, to encourage replacement of existing products with the clean technologies that is more environmentally friendly. There are many benefits of using green nanotechnologies as the new solution for energy in both their current availability and their current development. Over the new few decades, the highest growth opportunities will come from application of nanomaterials for making better use of existing resources. Nanotechnologies will help reduce weight of carbon emission in transportation utilizing nanocomposite materials that quickly diffuses across the automotive and aerospace industries. Applications of nanotechnologies will result in a global annual savings of 8000 tons of carbon dioxide, which will rise even further to over millions tons by 2020. But, let’s focus on the positive effects of Green Nanotechnology in Solar.
Nanotechnology is science, technology and engineering that is conducted at the nanoscale. The nanoscale is about 1 to 100 nanometres.
Nanotechnology is an area of science involved in designing, building and manipulating structures at the nanometer scale. A nanometer (nm) is one billionth of a meter, and it’s the size scale of molecules. For example:
Nanoparticles are defined as the microscopic particles with at least one dimension less than 100 nm. Nanoparticles are of immense scientific interest because of their vast potential applications in biomedicines, computer, electronics, and defense industries. Nanoparticles are of great scientific and technological interests because they can effectively act as bridge between the bulk form and atomic or molecular structures of the materials. Bulk materials possess constant physical and chemical properties regardless their sizes while nano-scaled materials possess varying properties depending on their sizes [Marignier, J.L., Belloni, J., Delcourt, M.O., Chevalier, J.P.
