4 Plasmon Resonances for PS@Au-Cu-Ag Composite Nanoshells 4.1 Introduction As shown in recent studies‚ various methods have been developed to expand the application area of noble metal nanoparticles and to control the morphology and the behavior. Composite microspheres with noble metal nanoshells have great advantages in catalysis‚ optics‚ conductivity‚ chemical sensors‚ and so on [1–5]. Moreover‚ these hybrid materials can prevent noble metal nanoparticles from agglomerating without the use of

Title: Cassava starch as an effective component for Ideal Biodegradable Plastic Proponent: Zhaira Morysette L. Maco‚ III-Narra student Introduction: Inventions have evolved and continue to evolve such that after several years of study‚ research and experimentation reach great developments. With continuing efforts to investigate the constituents of Philippine plants‚ we have pursued investigation of starch of the cassava plant (Manihot esculenta). Cassava tubers were gathered‚ ground and squeezed

Background Theory. Polyethylene Polyethyene is a type of polymer that is used in our daily life. Polyethylene(abbreviated PE) is a thermoplastic polymer‚ meaning that is can be melted to a liquid state and remolded as it returns to a solid state. PE is chemically synthesized from ethylene‚ a compound that is usually made from petroleum or natural gas[1]. The main mechanical properties of PE are the ultimate tensile strength and the modulus of elasticity. There are different types of Polyethylene

their useful material properties and low production costs. Almost every product is constituted of some kind of polymer; however‚ traditional synthetic polymers (often called plastics)‚ such as polypropylene and polyethylene‚ are derived from non-renewable petrochemicals and are not readily biodegradable (http://www.plastice.org/ fileadmin/files/Brochure_teachers.pdf). The need for polymers and the products they constitute is ever increasing; however the use of non-renewable fossil fuels for plastic

Polymer-inorganic nanocomposite present an interesting approach to improve the separation properties of polymer material because they possess properties of both organic and inorganic such as good permeability‚ selectivity‚ mechanical strength‚ and thermal and chemical stability.
