High-resolution low-frequency Raman scattering measurements from embedded AgAu nanoparticles unveil efficient scattering by harmonics of both the quadrupolar and the spherical modes. Comparing the experimental data with theoretical calculations that account for both the embedding medium and the resonant Raman process…
Abstract Using conventional methods to synthesize magnetic nanoparticles (NPs) with uniform size is a challenging task. Moreover, the degradation of magnetic NPs is an obstacle to practical applications. The fabrication of silica‐shielded magnetite NPs on carbon nitride nanotubes (CNNTs) provides a possible route to o…
Deposition of submonolayer coverages of 3,4,9,10-perylenetetracarboxylic diimide onto NaCl(001) results in the bimodal growth of coexisting square and needle-shaped islands. The epitaxy of each island type was determined from molecular and atomic resolution noncontact atomic force microscopy images. Postdeposition, th…
Polymer electrolyte is an important component in many multilayer devices such as batteries, fuel cells, and electrochromic devices. The effects of polymer electrolyte solidification on the ionic movement and device performance are presented based on near-infrared (IR) (860-2500 nm) electrochromic (EC) devices using th…
Single crystalline ZnO nanowires and nanorods were synthesized by a new sol−gel method carried out through formation of liposome−ZnO nanocomposites with or without hydrothermal reaction, respectively, and they were characterized to be hexagonal wurtzite structure by measurements of XRD patterns and SEM and TEM images.…
Abstract In this study, it was found that images scanned by a non‐contact optical instrument for topographic characterisation based on the principle of chromatic aberration give sufficient information to know the exact location of soil release polymer (SRP) deposition over fabrics. Through the comparison of reflected…
Abstract A facile approach for synthesis of hyperbranched polycarbosilane from AB 2 monomer via UV‐activated hydrosilylation is presented in this communication. The polymerization process was monitored using real‐time FTIR spectroscopy and the resulting hyperbranched polycarbosilanes were characterized using 1 H‐NMR,…
Micro-structures that mimic the extracellular substratum promote cell growth and differentiation, while the cellular reaction to a nanostructure is poorly defined. To evaluate the cellular response to a nanoscaled surface, NIH 3T3 cells were grown on nanodot arrays with dot diameters ranging from 10 to 200 nm. The nan…
This study discusses the photoalignment effect in a liquid-crystal (LC) film that is doped with nanoparticles and azo-dye. The vertical alignment induced by nanoparticles of polyhedral oligomeric silsesquioxanes can be changed into homogeneous alignment by the absorption of photoexcited azo-dye. An electrically tunabl…
We report the incorporation of various inorganic nanoparticles (NPs) (PbS, LaOF, LaF(3), and TiO(2), each capped by oleic acid, and CdSe/ZnS core/shell QDs capped by trioctylphosphine oxide) into vesicles (d = 70-150 nm) formed by a sample of poly(styrene-b-acrylic acid) (PS(404)-b-PAA(62), where the subscripts refer…
Structural, magnetic, and magnetotransport behaviors of ${\text{Fe}}_{2}{\text{V}}_{1\ensuremath{-}x}{\text{Cr}}_{x}\text{Al}$ Heusler-type alloys have been investigated in the present work. From the detailed analysis of data it is observed that increasing Cr content promotes site disorder of Fe and Al, which in turn…
Abstract Reaction of a rigid conjugated clamp‐like multi‐pyridineligand N , N ′‐bis(pyridin‐3‐yl)‐2,6‐pyridinedicarboxamide (H 2 L) with CuSO 4 · 5H 2 O or Cu(OAc) 2 resulted in the formation of two high‐nuclearity, discrete molecular copper(II) complexes, namely [Cu 10 (H 2 L) 5 (SO 4 ) 8 (μ 3 ‐OH) 4 (H 2 O) 2 ] · 4C…
Abstract The effect of microstructure modifiers, Sn and Ag, on the corrosion rate of commercial Pb–Ca alloy in H 2 SO 4 electrolyte was investigated by the potentiodynamic polarization and by the weight loss corrosion rate measurement at the open circuit potential. The effect of microstructure modification of the Pb–C…
For the first time, single and dual mode novel left-handed coupled line couplers implemented on ferrite substrates are reported. Both of the proposed couplers demonstrate novel characteristics of coupler operation with properties of tunability and non-reciprocity, which have not been demonstrated before. The proposed…
The dispersion diagrams of surface plasmon polaritons have been calculated for rectangular gratings, with very narrow wires, of varying depths. For gratings with a moderate height a family of vertical-standing-wave resonances may be excited, which consist of surface plasmons, oscillating on either vertical surface, co…
Superconductivity and phase relationships were explored in the Na-Fe-As system. The PbFCl-type 111 phase is stable only within a Na stoichiometry range of 1.00 to $\ensuremath{\sim}0.85$, and exhibits bulk superconductivity within an even narrower range around 0.90 in ${\text{Na}}_{0.9}\text{FeAs}$. In particular, sto…
Abstract The purpose of this work is to evaluate a new tetra‐functional peroxide initiator and offer comparisons with a di‐functional peroxide commonly used in the production of controlled‐rheology polypropylene (CRPP) resins. CRPP resins have been produced by reactive processing in a batch mixer by using various equi…
An examination of the aqueous solution solubility and batch crystallization kinetics of l -isoleucine at the 250 mL scale size under a poly- and isothermal process condition is presented. Solubility data determined are consistent with the existence of two l -isoleucine polymorphic forms, in which both forms have diffe…
It is shown that an appropriate combination of thermal oxidation and high-pressure water vapor annealing for nanosilicon leads to efficient blue-band phosphorescence with a lifetime of several seconds. Based on spectroscopic analyses on both the temperature dependence of decay dynamics and the change in the peak wavel…
Using first-principles calculations, we report the adsorption of adenine dinucleoside on single-walled carbon nanotubes (CNTs) with various diameters and chiral angles. The calculations indicate that in addition to noncovalent $\ensuremath{\pi}\text{\ensuremath{-}}\ensuremath{\pi}$ interactions between the adenine bas…
