It is shown that several (single-mode) models (PTT, XPP) are basically special cases of the General Network model. The XPP model of Verbeeten et al (2001) is shown to give an identical response to a PTT model at high elongational rates, but the models differ in shear flow at high shear rates. The Giesekus term in the XPP model has actually no effect at any deformation rate except the generation of a second normal stress difference at small shear rates. The possibility of tailoring the shear flow response at high shear rates is explored. The res ....etc

Light Emitting Polymers (LEP)

Abstract

Light emitting polymers or polymer based light emitting diodes discovered by Friend et al in 1990 has been found superior than other displays like, liquid crystal displays (LCDs) vacuum fluorescence displays and electro luminescence displays. Though not commercialised yet, these have proved to be a mile stone in the filed of flat panel displays. Research in LEP is underway in Cambridge Display Technology Ltd (CDT), the UK.
In the last decade, several other display contenders such as plasma and field ....etc

ELECTROACTIVE POLYMERS(EAP)
ABSTRACT
Electro active polymers are soft actuation materials that are fastly replacing the conventional actuating materials such as piezo electric crystals, motors, screws etc:- As the name suggests, they essentially consists of a ionic polymer back bone metallic composite having positive counter ions. On the application of an electric field or small voltage, these EAPâ„¢s will bend towards the anode.
They have properties resembling human muscles a ....etc

Abstract

In foam extrusion, material density is the most significant factor affecting the product cost and therefore the profitability of the manufacturing process. A reduction in the density of extruded parts reduces the raw material cost and therefore increases its profitability. On the other hand, a reduction in foam density degrades the mechanical properties and geometrical accuracy of extruded parts. Therefore, a critical balance has always to be achieved in order to minimize the material cost while maintaining adequate strength and acc ....etc

Polymers in concrete have received considerable attention over the past 25 years. Polymer-impregnated concrete (PIC) was the first concrete polymer composite to receive widespread publicity. PIC has excellent strength and durability properties, but it has few
commercial applications. Polymer concrete (PC) became well known in the 1970s and is used for repair, thin overlays for floors and bridges, and for precast components. Polymer-modified concrete (PMC) has been used primarily for repair and overlays. Several limitations have slowed the use ....etc

ABSTRACT

The discovery of superconductivity brings a tremendous change in the field of Science and Engineering from twentieth century onwards. The zero receptivity (or infinite conductivity) of a metal is known as superconductivity and this property of metal can be observed only at very low temperatures. Researche ....etc
