A Full Laboratory Report on: The Detailed Microstucture of Primary Materials This report presents a study on the microstructure of 8 material samples using the proper optical microscopy techniques. Emphasis is given in sample preparation‚ the right use of transmitting and reflecting optical microscopy methods‚ and a detailed analysis of the distinct microstructure of metal‚ ceramic‚ and polymer materials. For metals and ceramics‚ preparation procedures include grinding‚ polishing‚ and surface

Bottled Water Proposal In recent times‚ one of the world’s favorite grab and go drinks has come into question whether it is safe enough to drink or not and that is bottled water. “In 2007‚ according to the BMC‚ the total spending on bottled water in the United States reached an estimated $12 billion‚ despite the availability of clean and inexpensive tap water”(Lee‚Warhol). Some people argue that bottled water is not only unsafe for us‚ but also for our environment and it is much more expensive

an overview of the smart materials. The various types of smart material are also presented in this paper. To get the clear idea about the smart materials‚ its definition and types are explained briefly. Some of the types of these include piezoelectric materials‚ magneto-rheostatic materials‚ electro-rheostatic materials‚ and shape memory alloys piezoelectric‚ Varieties of smart materials already exist‚ and research is being carried out extensively to derive new materials.

SMART MATERIALS 1. Introduction The primary characteristic of a ‘‘smart material’’ is that it has the ability to respond to external stimuli in a technically useful and technically controlled way. The words ‘‘technically useful’’ and ‘‘technically controlled’’ are emphasized since all materials respond to external stimuli of some sort or other (as a simple example‚ all materials respond to temperature by changing their volume)‚ however‚ to be considered a ‘‘smart material’’ the response must

Engineering Materials Msc. Shaymaa Mahmood Introduction to Eng. Materials : Since the earliest days of the evolution of mankind ‚ the main distinguishing features between human begins and other mammals has been the ability to use and develop materials to satisfy our human requirements. Nowadays we use many types of materials‚ fashioned in many different ways‚ to satisfy our requirements for housing‚ heating‚ furniture‚ clothes‚ transportation‚ entertainment‚ medical care‚ defense and all the

( PROD 20303 ) Materials & Manufacture Materials Selection Exercise In the lecture this week you were introduced to the idea of a systematic approach to materials selection. Within the discussion‚ a number of examples were provided of ways in which a short list of materials might be identified for a given type of product using key property criteria as the method of differentiating between possible selections. Final choice can then be made by grading the candidate materials against defined
