Many would argue that the common form of plastic has been one of the most revolutionizing invention of the human existence. Plastic is present in just about every field of view at any given time and the sheer amount of products that contain plastic is frightening. We may not think about how much plastic our race actually uses because it’s so deeply embedded into our lives, for example: during a trip to the grocery store The Great Pacific Garbage Patch is what most describe as a massive pool of

but it does have its benefits as well as its negative outcomes. When we recycle it benefits the environment, because there less demand for raw material, which is extracted from the earth. By recycling we can just melt and process the material we already have and use it again and again. We do not have to use it for the same thing we could use the material for other purposes. When aluminum is recycled as well as plastic you receive a CRV back, which is a tax that is charged to the consumer when he

generated between the particles of a powdered material by electrical discharge. This discharge results from energizing the sample by a momentary pulse of large electric current. One can summarize the sequential effects of this electrical pulse in five key steps: (1) spark plasma is generated (2) the sample is “plasma heated” (3) the sample is “joule heated”, (4) the particles fuse into a compact, solid object by electrical field diffusion, and (5) the material undergoes plastic deformation to further

Abstract Friction stir processing (FSP) has been applied by several researchers to produce surface modification of metallic materials. The feasibility to produce TiC and B4C particle reinforced aluminum (AA6360) hybrid matrix composites (AHMCs) were studied in this paper. The measured content of TiC and B4C powders were compacted into a groove of 0.5 mm X 5 mm. Double pass FSP was carried out using a FSW tool at rotational speed of 1600 rpm, processing speed of 60 mm/min and axial force of 8 kN

The Plastic Game: ideas • Goal: decrease the consumption of plastic bottles • Principle of the game: Each bottle, when produced, would be given a token, which would follow the way the bottle make from the production to the consumption, ending in the waste disposal. Once bought by a consumer, a system would automatically register this number in a database, as well as the name of the consumer. Once a year, the Plastic Game would take place (one per country). It would globally happen like

needless-to-say millions of dollars material loss. Therefore, the benefits brought about by corrosion are outweighed by its detriments. The fact is, about 33% of these costs could be diminished by using corrosion-resistant materials. Being defined as the sideways displacement of material from its original position on a solid surface performed by the action of another surface, wear is another mechanical property of materials that materials scientists consider when selecting materials in a design task. In order

1 To what extent is the cork industry guilty of complacency and a lack of innovation? The cork industry is guilty of complacency and lack of innovation because they failed to recognize the changes in the wine industry. The wine industry was experiencing a revolution where new producers from Australia, California and Chile had new and different requirements. It took only a matter of years for the industry to change completely and the cork industry did not jump on the band wagon when it needed to

Engine Fastener Safety Michael Adams Embry Riddle Aeronautical University As everyone in the Aviation industry knows safety is paramount to all aspects of flight operations.one aspect that gets overlooked by most people is how exactly the little bits and pieces create an aircraft that can operate safely. The importance of aircraft hardware is often overlooked because of the small size of most items. However, the safe and efficient operation of any aircraft depends upon the correct selection

stopping by each workstation during the next two weeks to implement these settings on your computer. In addition to these energy- and cost-saving strategies, recycling initiatives will be implemented. Containers for several types of renewable materials will be placed throughout the building. Containers for the following items will be placed in the break rooms, kitchens, and other central gathering areas on each floor. Metals: Metal products include items constructed primarily out of aluminum
