This technique makes the metal soft, and it can be cut and shaped more easily. For example, mild steel is usually heated to a red heat, after which it is allowed to cool slowly. Other metals like aluminum melt when heated to high temperatures. Therefore, care must be taken when annealing them. Annealed metals can be changed to any shape and size, and then allowed to cool slowly into their hard status (Groover, 2010 p57).
Ceramic Nanotechnology
Nanotechnology is the process of engineering functional systems at the molecular scale usually at the Subatomic level (American Ceramic Society, 2009 p123). It usually deals with structures of 100 nanometers or less. Its main purpose is to make materials cleaner, lighter and more précised. Ceramics is one of the areas where nanotechnology has led to the production of a wide array of materials with distinct performance and property. Nanoceramics exist in solid form ranging in the size of nanometers (10-9) to micrometers (10-6). A Large number of particles provide a large surface area that can be held together by Nanokote to give stronger, lightweight, brittle and thermal resistance ceramics (American Ceramic Society, 2009 p134).
Mould Manipulation Technique
Mould manipulation of polymers can help in overcoming mechanical and aesthetic weaknesses that are associated with the standard injection molding (Rudd & Long, 1997 p98). This can involve improving bulk properties like weld lines or manipulating orientation morphology enhancement. In this process, experimental outcomes of a rotating pin at the weld line of glass and talc-filled polypropylene are introduced (Rudd & Long, 1997 p98). Talc filled material ensures that pin rotation speed does not exceed 100 rotation per minute, and this enhances polymer strength. Glass filled material also enhances strength significantly, but not as compare to talc-filled material. Mould Manipulation technique also introduces the chances of producing other functional molding and polarity manipulation, usually in paint development (Rudd & Long, 1997 p99). Read More

Processing-structure-property relationships in (TPE-E) nanocomposites

...in the polymer matrix (Dzenis 2004). Iwahori, Ishiwata and Ishikawa (2003) argue that an understanding of the basic physical relationship in nano scale structural variables and micro scale properties of polymer nanocomposites is very important in this study. The development of polymer nanocomposites optimally using carbon nanotube and carbon nano fibre requires full comprehension of the processing structure property relationships. Aims of the Research The aim of the research is to develop improved materials properties in TPE-E nanocomposites using the processing structure property relationships. The...

Mechanical Engineering- Mechanical Project

...? Composite Materials properties. The utilisation of such materials dates back to many centuries, when Egyptian and Mesopotamian settlers began utilising a mixture of mud and straw in constructing durable houses (Seymour and Deanin 1987). These occurrences in 1500bc could be identified as the humble beginnings for composite development, as straw continued to be utilised in reinforcement of boats and pottery items. Mongols, began utilising composite bows around 1200AD, presenting improvements on the utilisation of composites. The Mongols combined wood, bone... and animal glue to create a powerful weapon, which provided them with significant military dominance during these ancient times. The modern era of composites began with the development of plastics, which contributed significantly towards increased utilisation of composite materials. The utilisation of plastics began in nearly 1900s, replacing natural resins previously utilised in composites. These plastics, however, had the weakness of lacking sufficient strength for structural requirements (Kulshreshtha and Vasile 2002). Owens Corning remains credited with the introduction of fibre glass in 1935, which ultimately solved the problem of plastics lacking sufficient strength. This invention remains the...

Direct Manipulation

...Direct manipulation interface Direct manipulation is a mode of interaction between a user and a computer that allows the user to continuously give commands and receive feedback in the form of objects made to represent specific actions and reactions (metaphors) in the real world. This interaction allows for direct execution of actions by the user with the notion of not having an intermediary such as a menu or command assisting them thereby creating an environment of virtual reality. Direct manipulation interface is an advancement of the earlier version of interface called the command line or text interface that requires the user to literally key in commands in navigating the computer’s...

Gene Manipulation

...Gene Manipulation We are entering an age of genetics. The biggest biological research project in history, The Human Genome Project, assured us that it will have our whole genetic structure designed. The media gives information regarding new scientific state regarding genes which are related to disease, environment, behaviors as well as personality traits so often that it looks like we are being given a publication of gene-of-the-week. Genes have already been found out of Cystic fibrosis, Huntington's disease. Fragile X syndrome, cancer of the breast, the incurable Alzheimer's disease, cancer of colon, bipolar disorder, obesity, sexual orientation, and alcohol related disorders, "crime, timidity,...

Mechanical properties and acoustic behaviour of screed

...mechanical properties and acoustic behaviour of screed Screed definition All residential, commercial or industrial buildings use screed to provide smooth and flat floor. Apart from this, it can be used to increase the structural strength of the base floor slab while increasing the depth of the slab as well. Screed is a well defined mixture of cement and fine aggregate, called soft concrete, which when mixed forms a layer of compact material. This is applied to the surface base in the specified thickness and for providing a surface finish for the receiving floor or roof/ ceiling. It can be used as a topping to provide dense concrete base for improving the structural depth...

Mechanical properties of chassis

...Mechanical properties of chassis What is the purpose of chassis in the car? Chassis refers to a structural assembly of the car’s body. It is a protective covering of a car, which keeps the dirt, moisture, and dust away from the moving parts. The chassis protects the driver from the parts that are on locomotion under the hood of the car, it also protects commuters from atmospheric conditions. The chassis protects the other vehicle parts from any damage, as well as holding the main parts of the vehicle together. Mechanical properties of chassis The Poisson ratio, density, yield strength, and young’s modulus constitute the mechanical...

Microelectronics and Two Major Infrastructures: Photolithography and Particle Beam Lithography

.... (2011), the ECM is seen to possess properties that promote a unique microenvironment that fosters tissue organisation. This tissue organisation thus serves as the basis of designing and fabrication of biocompatible scaffolds that leads to tissue engineering. The preparation of scaffold with micro bristle on them to do cell culturing is very instrumental in tissue engineering (Lubick and Betts, 2008). There are three major design examples commonly identified with the deigning of a scaffold. The first of these is the use of scaffolds in cardiomyocytes, which is achieved as ECM forces cardiomyocytes to couple mechanically (Dvir et al., 2011). It would be noted that the cardiomyocytes is a...
