Download file to see previous pages Scanning probe microscopy has grown in use over the years and its applications span multidisciplinary approaches. The various disciplines that are utilising scanning probe microscopy include (but are not limited to) material sciences, biology, physics, engineering, chemistry, computer sciences, medicine, space science etc. (2) SPM techniques have been utilized to discover the atomic structures and interactions of various materials so as to enhance the use of novel materials in nano applications. (3) Similarly, SPM has found extensive use in biological applications such as biomedical research and characterizing plant cell walls as well as animal cell walls. (4) SPM is also finding new inroads into the world of computing and this paper will be concerned largely with the application of two SPM techniques to the development and fabrication of nanoscale electronics and computers. The fields of scanning tunneling microscopy (STM) and atomic force microscopy (AFM) will be analyzed in the context of their current positions for advancement in research relating to computing and electronics applications. A typical arrangement for SPM is shown in the figure one below. Quantum computers are computational devices that rely on the quantum-based mechanical phenomenon for example entanglement and superposition in order to carry out data based operations. Regular computing relies on transistors that have been scaled down and are being scaled down to promote miniaturization. (1) Quantum properties are relied on largely in order to represent data as well as to perform operations on data. One of the biggest advantages offered by quantum computers is the fact that they can process many different streams of data and instructions while conventional computers are limited in this respect. (1) Given the need for greater computing power along with cryptanalysis and analysis of multivariable systems, it is highly unlikely that conventional computing will be able to keep up with the demand for greater computing power.  ...Download file to see next pagesRead More

Scanning Electron Microscopy

...of incident electrons are produced by a field emission cathode (FE) or by a thermal emission source like a heated tungsten filament. The tungsten filament is used for the thermionic emission of electrons because of the fact that it has the lowest vapour pressure and the highest melting point compared to all other metals. This makes it possible to heat it long enough to release electrons. Electric current is used to heat up the filament. A typical tungsten filament electron gun for scanning electron microscopy has a diameter of about 100 micrometers. In operation, the filament will be heated by passing electrical currents through it. When the heat generated is enough to overcome the work function of...

Low Voltage Scanning Electron Microscopy

... Low Voltage Scanning Electron Microscopy Low voltage scanning electron microscopy denotes the use of scanning electron microscopy, which uses few kilo electron-volts (<5 keV) for accelerating the electron beam used in scanning. Low-voltage electron microscopes (LVEM) have proven to be effective in comparison to High-voltage electron microscopes (HVEM). Both types of microscopes work on the same principles, but the significant different between them results from the effect of electron acceleration voltage variation, which is applied in their respective designs (Schatten & James, 2007). Working Principles of Scanning Electron Microscopy (SEM) Scanning electron microscopes (SEMs) are microscopes, which produce sample images by scanning... from the projected beam as well as density and atomic number of the material under observation as the sample. Technically, the differences between HVEM and LVEM are a result of differences in landing energy determined by the electron accelerating voltage. The acquired signals are detected and amplified to develop images. The differences of detected signals are represented by variations in brightness on the visual display. The resultant image is thus a representative of electron energy emitted from the sample’s surface through inelastic and elastic scattering. The...

Use of the scanning electron microscopy in the food industry

...?  Use of the scanning electron microscopy in the food industry  Use of the scanning electron microscopy in the food industry Introduction Scanning electron microscopy (SEM), as well as other techniques such as energy dispersive spectroscopy (EDS) is an effective tool used for the identification and characterization of particulate contamination and foreign body contamination of food. Whether foreign body contamination occurs during processing or packaging, identification of these foreign bodies needs to be rapid and efficient in order to trace the source of contamination. The capabilities of SEM in foreign body identification make the...

To be successful, an orgnisation must meet some criteria, which include aligning the organisation's culture to the demand of the business, recruiting the best staff as well as empowering the staff through motivation, and involving the staff in decision-making process. Constantly the organisation is supposed to invest in knowledge management so as to empower its employees. Efforts to improve both internal processes as well as the external process in an organisation should also involve adopting the right technology so as to improve production and service delivery in the...

Light Microscopy

...Swarnambika S Academia Research Light Microscopy October 9, 2007 Light Microscopy Microscopes that use visible light as a source of illumination are called light microscopes. Today’s light microscopes are compound microscopes. They provide greater magnification and are much easier to use. Compound microscopes have two lenses, an objective lens and an ocular lens, both of which are corrected lenses (several individual lenses bonded together) that compensate for the aberrations inherent in ordinary lenses (James & Tanke, 1991). Uncorrected aberrations produce images that are surrounded by colored rings (chromatic aberration), and not all parts of the field of observation are simultaneously in focus (spherical aberration). Parts... systems...

Techniques for roadway tunnelling

...Review of TECHNIQUES FOR ROADWAY TUNNELLING Griffith School of Engineering, Griffith Gold Coast, QLD4222, Australia Tunnels have become a very critical aspect of infrastructure development. Conventional tunneling, cut and cover, cover and cut are three commonly used roadway tunneling methods. This treatise explores the three approaches to tunneling to determine how effective they are in roadway tunneling. Despite the different principles behind each of the methods, they have allowed for the creation of roadways in area where environmental and geographical constraints had hindered infrastructural development.
