The morphology, adhesion and tribological properties of the zirconia sol-gel coatings on phosphate treated, anodized and un-treated titanium surfaces were investigated. The anodization of titanium involves the formation ...

The techniques used to identify nanoparticle size and shape characteristics are of vital importance in the development of functional nanoparticles. Each technique offers different advantages; this work compares the two ...

Very thin spongy nanoporous gold films have a unique nanostructure and hence unusual properties. Our interest in these materials is also due to their wide range of potential applications [1,2]. An optical study for such ...

We examine the allowed modes of polarized electromagnetic waves moving through a doubly periodic material with a cermet topology. We present analytical results for the dispersion relations in two cases; firstly when the ...

This paper aims to give a brief overview of the current state-of-the-art in automatic measurement of affect signals in dimensional and continuous spaces (a continuous scale from -1 to +1) by seeking answer to the following ...

This work addresses current limitations of X-ray reflectornetry (XRR) for modeling thin films and provides a basis for their improvement. Better accuracy in the characterization of novel thin film structures requires ...

We investigate dispersion curves of coupled waveguides in hexagonal lattices. We find that their coupling coefficients change magnitude and sign along the BZ and that the modes here are no longer odd and even modes.

This paper outlines a theoretical formulation for the diffraction of plane waves by capacitive grids consisting of perfectly conducting cylinders, and focuses on the importance of the acoustic (lowest frequency) mode as ...

Ultrafast laser direct write micro-fabrication has emerged as a significant enabling technology creating new opportunities in microphotonics. The talk will present recent results of the performance of laser written ...
