INTRODUCTION

The term "nanotechnology" has evolved over the years via terminology drift to mean "anything smaller than micro technology such as nano powders, and other things that are nanoscale in size, but not referring to mechanisms that have been purposefully built from nanoscale components. This evolved version of the term is more properly labeled "nanoscale bulk technology," while the original meaning is now more properly labeled "molecular nanotechnology" (MNT), or "nanoscale engineering," or "molecular mechanics," or "molecular machine systems," or "molecular manufacturing."
MNT represents the state of the art in advances in biology, chemistry, physics, engineering, computer science and mathematics. The major research objectives in MNT are the design, modeling, and fabrication of molecular machines and molecular devices. The emergence of MNT - both infant and mature - has numerous social, legal, cultural, ethical, religious, philosophical and political implications.

BACKGROUND

Approximately 15 years ago scientists and engineers began discussing a technological revolution that would be as dramatic and far-reaching to society as the industrial revolution - the nanotechnology revolution. At first the primary promoters of the nanotechnology revolution were considered eccentric at best and a little crazy at worst. However, their ideas and visions are becoming accepted by the mainstream intellectual, scientific and engineering communities. Recently, governments and major corporations around the world have committed several billion dollars per year for the advancement of nanotechnology and nanoscience research and development.

OVERVIEW

Nanotechnology is a diverse collection of fields, touching on biology, medicine, materials, computers, manufacturing, physics, and several others. The distinctions are often blurred, sometimes deliberately for funding or theoretical purposes. Readers-and even some nanotechnologists-may

    What is Nanotechnology Manufacturing? The concept behind Nanotechnology is maneuvering molecules and/or atoms to fabricate resources and formations straightforwardly, in addition to utilizing the exclusive traits of matter at the Nano scale. The definition of technology is "the application of science and scientific knowledge for industrial or commercial objectives," then in its most simplistic form, nanotechnology is defined as "the application of science and scientific knowledge, at the Nano scale, for industrial or commercial objectives." In order to understand the size of material/matter involved at the Nano scale level, one needs to trace down the units of measurement, commencing with an ant (at the mill scale) and ending at the very bottom, at the Nano scale. The Nano scale is far…

    Nanotechnology can be defined as the science and engineering involved in the design, synthesis, characterization, and application of materials and devices whose smallest functional organization in at least one dimension is on the nanometer scale or one billionth of a meter. At these scales, consideration of individual molecules and interacting groups of molecules in relation to the bulk macroscopic properties of the material or device becomes important, since it is control over the fundamental molecular structure that allows control over the macroscopic chemical and physical properties. Applications to medicine and physiology imply materials and devices designed to interact with the body at subcellular (i.e., molecular) scales with a high degree of specificity. This can potentially translate into targeted cellular and tissue specific clinical applications designed to achieve maximal therapeutic affects…

    The basic definition of nanotechnology is the engineering of functional systems at the molecular scale. Both current work and concepts are cover and more advance in this technology (Acknowledging your sources, n.d.). It is also refers to construct items from the bottom up due to the ability of projected for higher performance using the modern technology and tools. Nanotech is also a study of atom and molecules around us that we implemented in our daily lives. The structures of its size is between 100 nanometers or smaller in at least one dimension and when it developing materials it will be within that size. Hall B. et al. (2007) discussed that nanotechnology meaning is nanotechnology is the general term for a large number of different scientific disciplines dealing with the characterization and development of materials on the nanometer scale - 1 nanometre is 1 billionth of a metre. Nanotech is much commonly found in cosmetics brand, medicine, energy and electronics. It brings modern to all the field with the development of nanotech. There are implication of the nanotech which we can see in the toxicity that it might produce after a period of time in cosmetic, where it might contribute in the effects on global economics and health (Acknowledging your sources, n.d.).…

    Carbon Nanotubes

    • 6618 Words
    • 27 Pages

    Carbon nanotubes (CNTs) are a recently discovered allotrope of carbon. They take the form of cylindrical carbon molecules and have novel properties that make them potentially useful in a wide variety of applications in nanotechnology, electronics, optics, and other fields of materials science. They exhibit extraordinary strength and unique electrical properties, and are efficient conductors of heat. Inorganic nanotubes have also been synthesized. A nanotube is a member of the fullerene structural family, which also includes buckyballs. Whereas buckyballs are spherical in shape, a nanotube is cylindrical, with at least one end typically capped with a hemisphere of the buckyball structure. Their name is derived from their size, since the diameter of a nanotube is on the order of a few nanometers (approximately 50,000 times smaller than the width of a human hair), while they can be up to several millimeters in length. There are two main types of nanotubes: single-walled nanotubes (SWNTs) and multi-walled nanotubes (MWNTs). Manufacturing a nanotube is dependent on applied quantum chemistry, specifically, orbital hybridization. Nanotubes are composed entirely of sp2 bonds, similar to those of graphite. This bonding structure, stronger than the sp3 bonds found in diamond, provides the molecules with their unique strength. Nanotubes naturally align themselves into "ropes" held together by Van der Waals forces. Under high pressure, nanotubes can merge together, trading some sp2 bonds for sp3 bonds, giving great possibility for producing strong, unlimited-length wires through high-pressure nanotube linking…

    There has been much new advancement in the nano-technology field on a international level in recent years. The new advancements have drawn a increasing interest in nanometer scale surface coating. Ultra thin film coatings can be used in a wide range of applications as lubricants, anti-stiction layers, molecular glues, coupling agents or adhesion layers. The mentioned molecular coatings are used to modify material surface properties. The traditional coating deposition methods consist of a set of sequential wet baths. The wet processing method is complex and limits the ability of molecular coating in many MEMS applications. The use of liquid precursors has extremely limited bath life, which cause the method to be highly expensive and have low product ability. In this paper a new surface coating technique a new surface coating technique will be discussed, which is called Molecular Vapor Deposition (MVD). This new method has proven to overcome the shortcomings of the liquid phase method and has single handedly improved changed the ability of surface coatings.…

    Nanotechnology is defined as the branch of science that deals with the development of functional systems at a molecular scale and involves the manipulation of individual atoms and molecules (Responsible Nanotechnology, 2002; United States Nanotechnology Inititaive, 2014; Dictionary.com, 2014). According to James B. Lewis Enterprises (1986), Fanfair, Desai and Kelty (2007), the idea of nanotechnology was first brought about in 1959 by physicist, Richard Feynman, however the term nanotechnology was not used. Feynman suggested that in the future it would be possible to precisely manipulate atoms and molecules. It was not until 1981, when the scanning tunnelling microscope (which allowed scientists to see individual atoms) was created, that nanotechnology began to be developed (Rouse, 2005; United States Nanotechnology Inititaive, 2014; Nanotechnology, 2009). Nanotechnology is described as evolutionary and revolutionary, as it will not only bring about new medical procedures, but also revolutionise the current ones. Nanotechnology will also assist with the development of producing more effective sources of energy. It can be argued that with the development new technologies, weapons will also be advanced. Nanotechnology may also cause a loss of jobs and certain stock markets to crash, such as diamond, oil and steel.…
