The synthesis and assembly of components are key steps in micro/nano device manufacturing. In this article, we report an optically controlled assembly method that can rapidly pattern micro/nano devices by directly assembling ions and nanomaterials without expensive physical masks and complex etching processes. Utilizing this controllable process, different types of device components (e.g., meta...

Pristine complex quaternary hydride (LiBH4/2LiNH2) and its destabilized counterpart (LiBH4/2LiNH2/nanoMgH2) have recently shown promising reversible hydrogen storage capacity under moderate operating conditions. The destabilization of complex hydride via nanocrystalline MgH2 apparently lowers the thermodynamic heat values and thus enhances the reversible hydrogen storage behavior at moderate te...

In recent years, nanoscale fabrication has developed considerably, but the fabrication of free-standing nanosize components is still a great challenge. The fabrication of metallic nanocomponents utilizing three basic steps is demonstrated here. First, metallic alloys are used as factories to produce a metallic raw stock of nano-objects/nanoparticles in large numbers. These objects are then isol...

Evolutionary computation for image processing is an encouraging research area. Transmission electron microscopy (TEM) images when used to characterize metallic and non-metallic nano-particles (size, morphology, structure, or composition), need such advanced image processing algorithms. This paper presents an efficient evolutionary computational method, particle swarm optimization (PSO), for aut...

We investigate the use of a metallic nano-cavity on dielectric waveguides for sensing applications. Nowadays the fabrication of metallic structures featured by challenging dimensions is feasible thanks to the most recent technologies such as EBeam Lithography (EBL) and lift-off [1]. We propose here to study the simulation, fabrication and characterization of such structures at the telecom wavel...

metallic nanoparticles can exhibit very large optical extinction in the visible spectrum due to localized surface plasmon resonance. spherical plasmonic nanoparticles have been the subject of numerous studies in recent years due to the fact that the scattering response of spheres can be analytically evaluated using mie theory. however a major disadvantage of metallic spherical nanoparticles is ...

Tuning localized surface plasmon resonance (LSPR) of nanoporous metals is crucial to manipulate light within tiny volumes for the implementation of optical devices at the nanoscale. Herein, nanoporous gold-alumina core-shell films with constant gold skeleton and variable alumina sheaths are fabricated by means of chemical corrosion and subsequent atomic layer deposition. Optical transmission pr...
