This work is aimed at developing suitable nano-sized ceramic inks (nano-inks) for the ink-jet printing four-colour process. Nano-inks of different pigment composition were prepared with various solid loadings, and their chemico-physical properties, relevant for the ink-jet application, were measured. Moreover, penetration kinetics of the inks through different unfired ceramic tile bodies was ex...

Using the transfer matrix method, the effect of temperature on thetransmission spectra of thermal tunable nano metallic photonic crystal filter has beeninvestigated. Three different materials H (high refractive index material), L (lowrefractive index material) and M as a metallic layer, have been used to make thisstructure. M layer is considered to be Silver. The complex refractive index of Sil...

In this work, we performed an extensive theoretical and experimental study to unveil the underlying mechanisms related intensified transmittance in epsilon-near-zero (ENZ)-integrated plasmonic nano-apertures. The occurrence of phase singularities at incident side nano-apertures results reduction transmittance. We show that enhancement ENZ-integrated nano-slits is attributed annihilation by ENZ ...

Title: METALLIC NANO-PARTICLES AS FUEL ADDITIVES IN AIR-BREATHING COMBUSTION Gregory Young, Doctor of Philosophy, 2007 Directed By: Associate Professor, Dr. Kenneth H. Yu, Department of Aerospace Engineering For volume limited propulsion systems, the use of metals as fuel additives offers to increase performance by increasing the volumetric energy stored in the fuel. Highspeed airbreathing comb...

This paper demonstrates the possibility of efficient adiabatic nano-focusing of plasmons by a sharp triangular metal wedge. Geometrical optics approach and the approximation of continuous electrodynamics are used for the analysis. In particular, it is demonstrated that both the phase and group velocities of an incident anti-symmetric (with respect to the magnetic field) plasmon tend to zero at ...

Embedding nonlinear media in the slit region of metallic nano-optic lens is proposed as a new method of active modulating the output beam. Two important phenomena, beam deflection and focusing, have been studied in detail. A developed Finite Difference Time Domain (FDTD) method has been performed to account for the nonlinear response. The simulated results show that the deflection angle and foc...

The dewetting process, which appears upon laserinduced melting of flat nanostructures and leads to a jumping of the droplets off the surface, is used for deposition of nano-particles onto a second substrate. Limitations in materials and particle sizes are discussed and experimentally verified. The experiments show that a variety of metals can be deposited in a size ranging from tens up to sever...

Recent progress in microand nanofabrication techniques enables the creation of hierarchically architected microlattices with dimensional control over six orders of magnitude, from centimeters down to nanometers. This hierarchical control facilitates the exploration of opportunities to exploit nano-sized material effects in structural materials. In this work, we present the fabrication, characte...
