Microspheres can function as optical superlenses for nanoscale super-resolution imaging. The imaging performance is mainly affected by the size and refractive index of the microsphere. Precise control of these parameters is a challenging task but of fundamental importance to the further development of the technique. In this study, we demonstrate for the first time a nanoparticle-hybrid suspensi...

in comparison to the previous researches, zro2 nanoparticles with higher surface area (85 m2/g) have been synthesized in this research. the as-prepared zro2 nanoparticles by co-precipitation method were characterized with x-ray diffraction (xrd), scanning electron microscopy (sem) and transmission electron microscopy (tem). the surface area of the sample was characterized by bet method. the eff...

The improvement of electrical conductivity of carbon-fiber reinforced plastics (CFRP) has been investigated by conductive silver nano-particles coating for the purpose of aircraft lightning protection. Silver nano-particles in colloid were sprayed on the surface of carbon fibers, which were then impregnated by epoxy resin to form a CFRP specimen. Electrical resistance was measured by contact re...

The correlation between density and specific surface area of ZrO2 nanoparticles (NPs) was studied. The NPs were produced using a hydrothermal process involving microwave heating. The material was annealed at 1100 °C which resulted in an increase in the average grain size of the ZrO2 NPs from 11 to 78 nm and a decrease in the specific surface area from 97 to 15 m(2)/g. At the same time, the dens...

New MoO3 or WO3 modified CeO2-ZrO2 aerogel catalysts were elaborated using the sol gel method combined to supercritical drying for NO-SCR by NH3 in excess of O2. XRD, N2-Physisorption, NH3-TPD, H2-TPR and DRUV-Vis spectroscopy used analyse samples. The results reveal that all powders (ZrO2, CeO2-ZrO2, MoO3-ZrO2, WO3-ZrO2, MoO3-CeO2-ZrO2 WO3-CeO2-ZrO2), calcined at 500 °C, are nanostructured mes...

•Several materials have been investigated for use in nano-CMOS technology, such as ZrO2, TiO2, BST, HfO2, Al2O3, SiON, and Si3N4. •Intel has recently prototyped a processor called Penryn using such transistors of 45nm technology. •For compact modeling based study of high-K non-classical transistors using BSIM4/5, two possible options can be considered: (i) varying the model parameter in the mod...

This review outlines the state of art, processing techniques, and mechanical testing methods zirconia (ZrO2)-based composites reinforced by carbon nanotubes (CNTs). The use CNTs as a secondary phase in matrix is motivated their outstanding crack self-healing ability, possibility to tailor desired nano-structural properties, exceptional wear behavior. Therefore, detailed investigation into CNT f...
