cadmium sulfide nanoparticles were grown using wet chemical method by dissolving the reactants ofcadmium acetate and sodium sulfide in the presence of thioglycerol (tg) as capping agent in ethanolsolvent. different nanoparticle sizes and size distribution were obtained through varying the molaritiesof thioglycerol. at higher tg concentration, synthesis provides a nearly monodisperse nanoparticl...

We reveal new stripe states in deformed hexagonal array of photonic wave guides when the array is terminated to have a ribbon-shaped geometry. Unlike the well-known zero energy edge modes of honeycomb ribbon, the new one-dimensional states are shown to originate from high-energy saddle-shaped photonic bands of the ribbon’s twodimensional counterpart. We find that the strain field deforming the ...

Nanocrystalline ZnO powders are synthesized using a quick, simple and inexpensive combustion method. Glycine and zinc nitrate, used as fuel and oxidant/cation sources respectively, were mixed together at room temperature to form a slurry or gel. A series of experiments were performed to synthesize nanoparticles for different fuel to oxidant ratios. The rate of heating and stirring greatly influ...

A innovative geometry of fractal microstrip antenna has proposed which can be used for various multiband applications. This hexagonal fractal antenna structure has designed to produce multiband characteristics or to achieve miniaturizations. Multiple hexagons of the proposed geometry of an antenna are interconnected to maintain conductivity and to preserve electrical self-similarity. The hexago...

In this paper, a hexagonal shape wearable antenna is presented .the proposed antenna is having EBG structure embed in the inner substrate layer. The antenna resonates at 2.45 GHz. When antenna is incorporated with EBG cell structure, it shows improvement in gain by 1.9 dB and 33% bandwidth improvement. The EBG structure consists of just a 3x3 elements but reduces backward radiations considerabl...

Broadly tunable multiple high-harmonic conical beams have been generated by means of a multistep χ(2) cascade processes in a two dimensional nonlinear photonic crystal. The nonlinear structure consists of a square lattice of inverted hexagonal domains with diameters and distances between domains as low as 1 μm. The large number of reciprocal lattice vectors provided by both the squar...

the internal structure of dna-ctab and dna-ddab is investigated by a small angel x- ray scattering(saxs) instrument. hexagonal packing of dna was observed for dna complex with ctab, and for ddabcomplex is observed lamellar structure. variations in the internal spacing and degree of long-range ordering aredependent on both surfactant type and concentrations of added salt. when we increased the a...
