In the automotive industry, the demanding of the more efficient vehicle had being discovered important by the consumer. Energy consumption and air pollution must have to be reduced directly to make sure that vehicles are the green element for people. All of the characteristic of Aluminium such, good corrosion resistance, light-weight application and the recycling potential can be the good element to replace other element such copper or steel that are lack of the advantages than aluminium allo...
Basically, the product produced in this process can be categoried into 4 group, they are: light distillates, middle distillates, heavy distillates and others. The example of light distillates are liquid petroleum gas (LPG), gasoline, and kerosene. Apart from that, the products that can be classified as middle distillates are residential heating fuel and aautomoblie diesel fuels. Additionally, bunker fuel oils is an example of heavy distillataes, while petroleum cokes, lubricating oils and car...
> Many scientists view nanotechnology as the revolutionary technology of the 21st century. Just as plastics were a pervasive and revolutionary product of the 20th century, nanotechnology products are expected to have widespread use and change our lives in myriad ways. Nanotechnology products are currently in use in more than 200 consumer products,ranging from air conditioners to sunscreen. > Nanotechnology is based on matter that is so small that it exists in the atomic and molecular realm. A...
An organic light emitting diode (OLED), also organic electro luminescent device (OELD), is a light-emitting diode (LED) whose emissive electroluminescent layer is composed of a film of organic compounds. This layer of organic semiconductor material is formed between two electrodes, where at least one of the electrodes is transparent. Such devices can be used in television screens, computer monitors, small, portable system screens such as cell phones and PDAs, watches, advertising, information...
Tablets are solid dosage forms usually contains active pharmaceutical ingredient and excipients in powder, crystalline or granular form with or without diluents which is prepared either by moulding or compression process. They are solid, biconvex or flat in shape and vary in size, shape and weight which is depends on the medicaments which are used for preparation. They are also varying in hardness, disintegration; dissolution characteristics and thickness depend on their intended use and meth...
In the world of automotive industry a lot of metals have to be used to make the parts of an automobile. The metals found are of very rigid shapes and sizes and it cannot be directly used, to make the required sizes and shapes in the automotive industry the main metal working process used is the sheet-metal forming process. The sheet metal forming process is a process in which solid metals can be made into thin or flat pieces, and sheet-metal forming is one of the very fundamental methods in m...
Crystal field theory is a model that describes the electronic structure of transition metal compounds, all of which can be considered coordination complexes. CFT successfully accounts for some magnetic properties, colours, hydration enthalpies, and spinel structures of transition metal complexes, but it does not attempt to describe bonding. CFT was developed by physicists Hans Bethe and John Hasbrouck van VlecK in the 1930s. CFT was subsequently combined with molecular orbital theory to form ...
Magnetic levitation technology was initially invented by a French and an American engineer who did not see practical use of the technology back in early 1900s. As leaders in the rail system, Germany and Japan saw the potential use of magnetic levitation technology and applied it to passenger rail since there is growing demand for reliable high speed mode of transportation around the world due to increasing population growth and mobility. Up until now a number of firms have been researching th...
This chapter will discusses about the literature review of the background study, theory and method of previous research with a lot of references gathering that are very important to prove the experiment method and result in the project. Welding and joining processes are essential for the development of virtually every manufactured product. However, these processes often appear to consume greater fractions of the product cost and to create more of the production difficulties than might be expe...
Upon examination of their properties, Carbon Fibre was dismissed as a choice, due to its high cost and lower availability as compared to the other two choices. There was a close comparison between Chromoly Steel and Aluminium. The foldable bicycle is intended for city commuting, which would result in the rider carrying the bicycle often, and the high density, or weight, of Chromoly steel would make it impractical for use in a foldable bicycle's frame. Therefore, Aluminium was chosen as the ap...
