Plasmonic gratings and nano-particle arrays in a metal-insulator-metal structures are fabricated on an erbium doped silicon nitride layer. This material system enables simple fabrication of the structure, since the active nitride layer can be directly grown on metal. Enhancement of collected emission of up to 12 is observed on resonance, while broad off-resonant enhancement is also present. The...

Recently, much has been written about the extreme urgency of elaborating the regulations for engineered nanomaterials. Such regulations are needed both from lawmakers, to protect people from potentially adverse effects, and from industry representatives, to prove that nanoproducts are produced carefully and with caution to avoid possible lawsuits. However, developing regulations has proven to b...

Nan-sized inorganic particles having characteristic morphology and narrow size-distribution have attracted attention due to their potential applications as functional materials, i.e., catalysts, magnetic materials, conducting inks, and ferrofluids. Various preparation and stabilization methods of nano-sized metal particles, metal oxide particles, and metal sulfide particles have been reported. ...

in this study, for increasing absorption of the active layer in bulk hetero junction (bhj) organic solar cells (oscs) we used surface plasmon effects of metal nano particles (mnps). we embedded the mnps inside the active layer and studied the device structure. for shown the results we investigated the model of our structure with finite difference time domain (fdtd) numerical method and achieved...

A consistent conventional theoretical description is presented for anomalous lowenergy deuterium nuclear fusion in micro/nano-scale metal grains and particles. The theory is based on the Bose-Einstein condensate (BEC) state occupied by deuterons trapped in a micro/nano-scale metal grain or particle. The theory is capable of explaining most of the experimentally observed results and also provide...

During the last couple of years several ink manufacturers have presented metal nano-particle inks for inkjet printing. These inks provide low resistances on plastic and paper substrates, thus enabling manufacturing of high-conductivity conductors that could be used in circuit boards. Inkjet printing of a commercial silver nano-particle ink on paper and plastic substrates has been investigated. ...

To study the anomalous heat effect of Nibased binary-metal-nano-powder samples by gas-phase hydrogen isotope absorption/desorption, three kinds of samples CNZ, CNZ-II and NZ were tested for the temperature range 300-573 K. The highest excess heat power, ca. 2W/g-Ni was obtained with CNZ at 573 K. Peculiar H(D)-isotopic effect and sudden heat sink by abrupt H(D)-desorption were observed. The hea...

nano technology has a large number of applications in different fields of science and technology. nano particle are the tiny particles which are being used in upcoming technology due to their small size and high capability. the properties of nanoparticles depend largely on their synthesis procedures. there are different methods for the synthesis of nano particles using different conditions. in ...
