Nano-layer and micro-structure technologies for energy efficiency and sustainability

Hebrink T.J., 3M Company, US

Multilayer optical film technologies made with hundreds of nanolayers and microstructured film technologies can be used to manage building energy while maintaining architectural aesthetics. For example, visibly transparent (invisible) infrared mirror films are useful for [...]

Coupled surface plasmon resonance on rotated sinusoidal gratings at different azimuthal orientations

Csete M., Szalai A., Tóth E., Somogyi A., Balázs J., Szabó G., University of Szeged, HU

Theoretical study was performed on rotated grating coupling phenomenon on multilayers comprising 416 nm periodic sinusoidal polymer gratings with 35 nm modulation amplitude aligned on a bimetal film made of gold and silver layers. The [...]

Multilayer optical strip for illumination, imaging and analysis

Gomez-Gonzalez E., Marquez-Rivas J., Perales-Esteve M.A., Mayorga-Buiza M.J., University of Seville, ES

An optical device (multilayer optical strip, MOS) is presented. It is composed of a small-sized, strip-shaped, multilayer, planar structure connected to a control unit. Active and passive optical elements allow for controlling the properties, spatial [...]

Polymer Nanomanufacturing Strategies for Multifunctional Nanomaterials

Mead J., Barry C., Wei M., Busnaina A.A., University of Massachusetts-Lowell, US

Polymeric materials offer tremendous potential for preparing functional materials using nanoscale fillers and features. For example, the use of nanolayered materials in barrier or optical applications, nanofeatured materials for hydrophobic surfaces, and patterned polymer blends [...]

A New Route to the Formation of Nanoporous Capsules using Block Copolymer Thin Films & Colloids

Mantzana P., Sakai K., Biggs S., University of Leeds, UK

The objective of this project is the preparation of novel porous nanocapsules. Spherical colloidal particles, such as melamine formaldehyde (MF), are coated with a mixture of a multilayer of diblock copolymers/micelles and polymer coated Au [...]

An Analytical Model for Multi-layer and Multi-electrode Piezoelectric Ceramic Actuators

Wang B-L., Mai Y-W., The University of Sydney, AU

The use of piezoelectric ceramics in multilayer actuator is increasing. This paper studies electroelastic field concentrations ahead of electrodes for multilayer piezoelectric actuators. The electrodes are vertical to and terminated near the edges of the [...]

Interfacial Instabilities in Multilayer Extrusion

Ho K., Lee J.S., Viriyabanthorn N., Sung C., Barry C.M.F., Mead J.L., University of Massachusetts-Lowell, US

Polymeric alternating multilayer laminates have been prepared by coextrusion, utilizing a specially designed feedblock to combine the two incoming materials from different extruder. Layer multiplying elements (LME) were used to split the melt stream, divide [...]
