We demonstrate that the coupling between plasmonic modes of oriented metallic nanorods results in the formation of an extended (guided) plasmonic mode of the nanorod array. The electromagnetic field distribution associated to this mode is found to be concentrated between the nanorods within the assembly and propagates…
Experimental results on S segregation at growing Al2O3/alloy interfaces are reviewed for binary FeAl, NiAl alloys, and ternary alloys with additions of Cr, Pt, or a reactive element, such as Zr, Hf, or Y. The segregation behavior is thermodynamic in nature, but the segregation energy can change not only with alloying…
Near-monodisperse Bi dots in the diameter range of 3−115 nm are synthesized by a simple, solution-based one-step approach by varying the amounts of Bi[N(SiMe 3 ) 2 ] 3, Na[N(SiMe 3 ) 2 ], and a polymer surfactant, poly(1-hexadecene) 0.67 -co-(1-vinylpyrrolidinone) 0.33, employed. The reaction conditions are further mo…
Near-infrared fluorescent (NIRF) materials are promising labeling reagents for sensitive determination and imaging of biological targets. In the near-infrared region biological samples have low background fluorescence signals, providing high signal to noise ratio. Meanwhile, near-infrared radiation can penetrate into…
Various calcium phosphates are used for bone repair. Although hydroxyapatite (HA) sintered ceramics are widely used due to their osteoconductivity, its bioresorbability is so low that HA remains in the body for a long time after implantation. In contrast, tricalcium phosphate (TCP) ceramics show resorbable characters…
We demonstrate the possibility to achieve optical triggering of photochemical reactions via two-photon absorption using incoherent light sources. This is accomplished by the use of arrays of gold nanoparticles, specially tailored with high precision to obtain high near-field intensity enhancement.
The growing chain molecular dynamics (GCMD) simulation method, a new nonequilibrium molecular dynamics code, is proposed to simulate the polymer chain aggregation behavior during polymerization on a catalyst surface. We found that the growing chain crystallizes on the surface in two stages: the nucleation stage and th…
Ordered mesoporous materials are materials with well defined pore sizes in the range of 2 to 50 nm.This paper shows that suspensions of particles of mesoporous materials can be useful tools for organic and bioorganic synthesis.They can be used to overcome reactant incompatibility, as is demonstrated for a reaction bet…
Abstract The crystal structure of the quaternary compound CuTaInSe3 belonging to the system (CuInSe2)1‐x(TaSe)x with x= 0.5, was analyzed using X‐ray powder diffraction data. This material is isostructural with the CuFeInSe3 compound, and crystallize in the tetragonal space group P42c (Nº 112), Z = 1, with unit cell p…
RbAg 4 I 5 solid electrolyte films have been prepared using the pulsed laser deposition technique. Their structures have been characterized by x-ray diffraction, and the surface and cross-section morphologies have been investigated by using scanning electron microscopy. It was found that larger energy density of the l…
Abstract Electrostatic assembly of one species can be realized using gelatin as a polyampholyte. Under suitable conditions where the electrostatic attraction and repulsion were both significant and in balance, linear growth of multilayers driven by electrostatic interactions was sustained over many successive assembly…
The photocurrent characteristics of HgTe nanoparticle (NP) thin films fabricated on glass substrates were investigated under the illumination of 1.3 ?m wavelength light in this work. The photocurrent obtained from an NP thin film with a vertical structure was 119 ?A in magnitude at an applied voltage of 2 V. The magni…
An all-thin-film electrochromic device glass/ITO/NiO x /LiBSO/WO 3 /ITO was fabricated by magnetron sputtering, in which LiBO 2 + Li 2 SO 4 (LiBSO) was used as the new ion conducting layer. The average visible light transmittances of bleached and coloured states reached 56.8% and 4.6%, respectively, and the optical tr…
In this paper, a model of multiferroic heterostructure is constructed by growing an epitaxial piezoelectric film on a magnetostrictive layered manganite single crystal. By considering the efficient mechanical coupling at the interface, the magnetoelectric (ME) effect, especially for magnetically induced polarization o…
An alternative interpretation of the diffraction of blazed transmission gratings with moderate structure period is proposed according to a modified extended scalar theory (MEST). The diffraction field on the bottom facet of the grating is considered to be the interference of four subfields investigated in the problem…
Multiferroic properties of γ-Fe 2 O 3 –BiFeO 3 /Bi 3.25 La 0.75 Ti 3 O 12 epitaxial composite bi-layers grown on SrRuO 3 /SrTiO 3 (1 1 1) are compared with the properties of single phase BiFeO 3 and Bi 3.25 La 0.75 Ti 3 O 12 thin films. The composite bi-layers show well-saturated hysteresis loops with a low coercive f…
1 and 2 mole% of Mn doped CuGaS 2 (CGS) single crystals were grown by the chemical vapour transport (CVT) technique using iodine as the transporting agent. The analysis of the single crystal x-ray diffraction data suggests that the doping of 1 and 2 mole% Mn in the CGS single crystal does not affect the tetragonal (ch…
The catalytic combustion of diesel soot was studied in the presence of catalysts: CuZrO 2, KNO 3 ZrO 2, and CuKNO 3 ZrO 2 . The catalysts were prepared by impregnation of ZrO 2 · n H 2 O into an aqueous solution of Cu(NO 3 ) 2, KNO 3, or both salts simultaneously. The catalysts were characterized by X-ray diffraction…
Exciton effects in metallic carbon nanotubes with and without magnetic flux are studied in an effective-mass approximation. For parallel polarization, an exciton associated with the first excited bands has an appreciable binding energy even in the presence of strong screening of linear bands. The Aharonov-Bohm splitti…
Modern Drying Technology (MDT) is planned as a five-book series on advances of science and technology of the drying process. The idea of the book series on the subject is not entirely new and remin...
