The strong coupling between localized surface plasmons and surface plasmon polaritons in a double resonance surface enhanced Raman scattering (SERS) substrate is described by a classical coupled oscillator model. The effects of the particle density, the particle size and the SiO2 spacer thickness on the coupling strength are experimentally investigated. We demonstrate that by tuning the geometr...
The effect of particle size and the heat treatment on precursor powder and subsequent phase formation of silver tube Bi-2223 wire has been studied. First, we have prepared a series of Bi1.66Pb0.34Sr2Ca2Cu3Oy samples with different sintering temperatures and studied the phase formation in these samples. Second, different particle size distributions were obtained by grinding powders of best for...
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. ...
Soil particle size distribution and bulk density are used for estimating soil-moisture characteristic curve. In this model, soil particle size distribution curve is divided into a number of segments, each with a specific particle radius and cumulative percentage of the particles greater than that radius. Using these data, soil-moisture characteristic curve is estimated. In the model a scale f...

In this study PbZrO3 was prepared as a matrix by the sol-gel process and is characterized by XRD and SEM techniques. The particle size of the synthesized nanocomposite is evaluated about 43 nm. The Lead Zirconate is then doped with Ce3+/TiO2 in different ratios. Nanocomposites are added in the reaction in a photoreactor with a pollutant (an Azo dye) and as a result the degradation percentage is...
benzoyl peroxide (bpo) is a first-line topical treatment in acne vulgaris, and it is superior to antibiotics, because the bacteria do not develop resistance to it. skin irritation is a common side effect, and it has been shown that controlled release of bpo from a delivery system to the skin could reduce the side effects while reducing percutaneous absorption. therefore, the purpose of the pres...
background : this research provides an insight into exposure information and particle size distributions of bisphenol a (bpa), a common environmental hormone, at polycarbonate (pc) molding plants in southern taiwan. methods : the inhalable dust sampler as iom and the micro-orifice uniform deposition impactor (moudi) were used for samples collection to evaluate the level and particle size distri...
nanocomposite of zro2/zno was prepared under ultrasonic irradiation by sol gel process from directly mixing zirconium and zinc gels, and the mixture was placed under ultrasonic irradiation for 2 hours then aging time the filtrated composite gel was calcinated at 500°c for 3h in furnace. the precursor sol of zirconium was prepared from an aqueous solution of zrcl4 and zinc acetate dihydrated was...
as a native fermented dairy drink, doogh is an important industrial product in iran. however, its characteristics have not been completely evaluated. this study evaluated the flow behavior, particle size distribution and stability of non-fat doogh as affected by the row material employed (fresh skim milk or skim milk powder) and the total solids (ts) content of the final drink. the viscosity of...
