“SMART MATERIALS” ABSTRACT The world has undergone two materials ages‚ the plastics age and the composite age‚ during the past centuries. In the midst of these two ages a new era has developed. This is the smart materials era. According to early definitions‚ smart materials are materials that respond to their environments in a timely manner. The definition of smart materials has been expanded to materials that receive‚ transmit or process a stimulus and respond

honor that I speak before you at this momentous event. Tonight‚ we are celebrating the accomplishments of the past and the infinite possibilities of the future. And so‚ naturally‚ I’d like to begin with a story about failure. Or more exactly‚ driving-related failure. I didn’t take driver’s ed till I was 16‚ because I procrastinated as usual. But despite the fact that I took driver’s ed later‚ I passed the class with flying colors. Seeing this‚ I decided I was prepared to take the driver’s permit test

TYPES OF MAGNETIC MATERIALS Paramagnetic materials have a small‚ positive susceptibility to magnetic fields. These materials are slightly attracted by a magnetic field and the material does not retain the magnetic properties when the external field is removed. Paramagnetic properties are due to the presence of some unpaired electrons‚ and from the realignment of the electron paths caused by the external magnetic field. Paramagnetic materials include magnesium‚ molybdenum‚ lithium‚ and tantalum

RAW MATERIAL AND SOURCES OF AVAIBILITY The paint industry is raw material intensive. Paint involves the mixing of various raw materials in various proportions. The raw materials are of a wide variety. On an average‚ raw materials account for 60% of net sales (industry average). In case of small-scale units it forms up to 70% of the net sales. Raw materials are divided into three major groups‚ namely‚ pigments (titanium dioxide‚ zinc oxide etc.)‚ solvents (mineral turpentine) and resins and

| |Pipe is one of the more common types of plastic product we are familiar with. Pipe is produced by an extrusion process. Basically extrusion can be | |defined as forcing a material through a die orifice. This die orifice produces the final shape of the finished product. It is probably a bit of over| |simplification‚ but extrusion is somewhat analogous to squeezing toothpaste through a tube.
