    Alloy: An alloy is a metal composed of more than one element. Engineering alloys include the cast-irons and steels, aluminum alloys, magnesium alloys, titanium alloys, nickel alloys, zinc alloys and copper alloys. For example, brass is an alloy of copper and zinc

    Organic Chemistry

    Homologous series: A homologous series is a set of compounds whose components differ by a single repeating functional group...in the case of (straight chain) alkanes, CH2...and their general formula is CnH2n+2

    Plastics

    PET (polyethylene terephthalate) is a clear, tough polymer with exceptional gas and moisture barrier properties. PET's ability to contain carbon dioxide (carbonation) makes it ideal for use in soft drink bottles.

    HDPE (high density polyethylene) is used in milk, juice and water containers in order to take advantage of its excellent protective barrier properties. Its chemical resistance properties also make it well suited for items such as containers for household chemicals and detergents.

    Vinyl (polyvinyl chloride, or PVC) provides excellent clarity, puncture resistance and cling. As a film, vinyl can breathe just the right amount, making it ideal for packaging fresh meats that require oxygen to ensure a bright red surface while maintaining an acceptable shelf life.

    LDPE (low density polyethylene) offers clarity and flexibility. It is used to make bottles that require flexibility. To take advantage of its strength and toughness in film form, it is used to produce grocery bags and garbage bags, shrink and stretch film, and coating for milk cartons.

    PP (polypropylene) has high tensile strength, making it ideal for use in caps and lids that have to hold tightly on to threaded openings. Because of its high melting point, polypropylene can be hot-filled with products designed to cool in bottles, including ketchup and syrup. It is also used for products that need to be incubated, such as yogurt.

    PS (polystyrene) is a colorless plastic that can be clear and hard. It can also be foamed to provide exceptional insulation properties. Foamed or expanded polystyrene (EPS) is used for products such as meat trays, egg cartons and coffee cups. It is also used for packaging and protecting appliances, electronics and other sensitive products.

    There are two types of plastics; thermoplastics and thermoset plastics.

    Thermoplastics are basically the same chemically after moldeing as they were in the raw state. This means that these plastics can be remelted and reused.

    Thermoset plastics have a chemical reaction during the molding process which alters their chemical make-up, and therefore are not reused

    Some Commodity Plastics

    High Impact Styrene (HIPS) : is a cost effective material, that is light in weight with good impact resistance and surface finish. It is translucent in its natural state and translucent to opaque when coloured.

    Rigid PVC (UPPVC) : is a moderately priced rigid material that is strong, abrasion resistant, and naturally ignition resistant. It is co-extrudable with flexible PVC, to produce a wide range of unique applications.

    Flexible PVC (PPVC) : is a moderately priced flexible material, with a rubber or leather like feel. It is often the material of choice for bumper edges, gaskets and seals. Ideal for components that have to bend easily

    Acrylonitrile Butadiene Styrene (ABS) : is a rigid material noted for its structural rigidity, toughness, pleasant surface luster, and colourablity. It has a higher heat deflection temperature than PVC and is resistant to scuffing, staining, and chemicals.

    High Density Polyethylene (HDPE) : this material offers good chemical resistance, natural lubricity and provides excellent abrasion resistance.

    Polypropylene (PP) : is similar to high density polyethylene. It is the material from which the "living hinge" extrusions are made.

    Some Engineering and Specialty Plastics

    Polyurethane (PU) : is a flexible material, has excellent elasticity, resilience, abrasion resistance, high tear strength, and good resistance to fuel and oils.

    Nylon 6 (PA6) : a material which has high strength, toughness at low temperatures, stiffness, wear and abrasion resistance, low co-efficient of friction and good chemical resistance.

    Thermoplastic Rubber (TPR) : are flexible materials that provide better physical and thermal properties than PPVC.

    Polycarbonate (PC) : is a material that has good balance of toughness, clarity, high heat deflection, dimensional stability, excellent electrical properties and surface gloss.

    Gemstones

    A gemstone is a mineral, rock (as in lapis lazuli) or petrified material that when cut or faceted and polished is collectible or can be used in jewellery. Others are organic, such as amber (fossilised tree resin) and jet (a form of coal). Some beautiful gemstones are too soft or too fragile to be used in jewelry, for example, single-crystal rhodochrosite, but are exhibited in museums and are sought by collectors of mineral or crystal specimens

    check out the gallery's 20 different types of gemstones, find 4th paragraph of "Getting to Know Gemstones". you can see the colorful picture and different types of gemstones

    Cells

    Batteries are fascinating. There are many different kinds, but most work in the same way. Different types of batteries use different chemicals. Car batteries use lead and sulfuric acid. Cell phones and laptop computers use nickel and cadmium. The normal batteries you see in a store use alkaline manganese dioxide.
