This article reports on the fabrication and characterization of plasmonic interfaces composed of a sandwiched structure comprising a tin-doped indium oxide (ITO) substrate, gold nanostructures (Au NSs), and a thin ITO film overcoating. The change in the optical characteristics of the ITO/Au NSs/ITO interfaces as a fun…
Abstract We present a general method to fabricate niobate nanoparticles (NPs) by using hexaniobate Lindqvist ions as niobium source. First, soft‐chemical synthesis was adopted to prepare amorphous compound NPs, which subsequently served as parent bodies, affording not only nanoscale size but also optimal compositions…
It has been experimentally and numerically shown that transmission at near infrared wavelengths is selectively controlled by polarizations in two-dimensional complementary plasmonic crystal slabs (2D c-PlCSs) of stacked unit cell. This feature is naturally derived by taking account of Babinet’s principle. Moreover, th…
The effective vibrational density of states (VDOS) has been derived from inelastic neutron-scattering data, for isotopically substituted $\text{Si}\text{ }{^{18}\text{O}}_{2}$ and $\text{Si}\text{ }{^{16}\text{O}}_{2}$ glasses, to gain information about the relative contribution to the Si and O partial VDOS. This is a…
We examine the role of magnetic dipoles in single and coupled pairs of metallic split-ring resonators by numerically computing their magnitude and examining their relative contributions to the scattering cross section. We demonstrate that magnetic dipoles can strongly influence the scattering cross section along parti…
The growth of carbon nanotubes (CNTs) on natural materials is a low-cost, environmentally benign, and materials-saving method for the large-scale production of CNTs. Directly building 3D CNT architectures on natural materials is a key issue for obtaining advanced materials with high added value. We report the fabricat…
Regenerative tissue engineering requires biomaterials that would mimic structure and composition of the extracellular matrix to facilitate cell infiltration, differentiation, and vascularization. Engineered scaffolds composed of natural biomaterials silk fibroin (SF) and chitosan (CS) blend were fabricated to achieve…
Abstract Maleic anhydride grafted polypropylene (MAPP) was blended with ethylene–vinyl acetate (EVA) copolymer to form MAPP/EVA polymer blends. Wood powder (WP) was mixed into these blends at different weight fractions to form MAPP/EVA/WP blend composites. Differential scanning calorimetry (DSC) analysis of the blends…
Abstract The thermal properties (thermal conductivity, thermal diffusivity, and specific heat capacity) of nitrile rubber (NBR)/poly(vinyl chloride) (PVC) blends were measured in the temperature range of 300–425 K. The incorporation of graphite into the NBR/PVC (30/70) matrix improved its thermal properties. Moreover,…
We consider an axially elongated cholesteric elastomer having a twist defect. We show that its localized mode can be mechanically tuned, and the scaling of the inverse relative line width can be largely enhanced when the values of the deformation and shape anisotropy are near the pseudoisotropic curve. This choice cau…
We report on electron beam induced current (EBIC) from individual carbon nanotubes (CNTs) which are in contact with metal electrodes. The EBIC signals originate from the diffusion of excess carriers induced by the electron beam bombardment. The EBIC image enables us to locate the individual CNTs efficiently. From the…
Abstract In this study, we successfully fabricated highly aligned polyvinylpyrrolidone (PVP) fibers and crossed mats by restraining and eliminating the jet bending instability through a dual‐opposite‐spinnerets electrospinning (DOSES) method. The DOSES process was photographed by a digital camera, and the morphology o…
We studied the power-dependent photoluminescence of ZnO nanopowder grown by sol-gel method at low temperature. At moderate optical pumping intensity, two nonlinear emission bands due to the radiative recombination of free biexciton and the inelastic exciton–exciton scattering were detected. We found that the threshold…
Abstract Dickite particles were modified by silane coupling agent, hexadecyl phosphate, oleic acid, and stearic acid (SA), respectively. Modified dickite was composed with linear low‐density polyethylene (LLDPE) to prepare a series of LLDPE/modified dickite composites. Hydrophilicity of modified dickite was characteri…
Abstract Carboxyl multi‐wall carbon nanotubes (MWNTs‐COOH) were grafted by diaminopropyl terminated dimethylpolysiloxane (DPD) to the modified MWNTs‐COOH (MWNTs‐DPD). The surface structure and thermal stability of MWNTs‐DPD and MWNTs‐COOH were characterized using Fourier‐transform infrared spectroscopy, X‐ray photoele…
Gd-C(4)-thyroxin-DTPA, a potential MRI contrast agent, was synthesized from Gd-DTPA and thyroxine, which interacts strongly with human serum albumin (HSA). It was characterized in water by its relaxometric properties and its stability versus zinc transmetalation. The affinity of the complex for HSA was studied by usin…
A series of pure and Nd 3+ -doped La 2 CaB 10 O 19 (LCB) crystals have been grown along different crystallographic directions, [001], [010], [100], [101], ∼[±1,−1,0], and ∼[±1,1,0], respectively, by the top-seeded solution growth (TSSG) method. The effect of seed orientations on the morphologies and the key limiting f…
The crystal structure of the dinB gene product from Geobacillus stearothermophilus (GsDinB) is reported at 2.5 A resolution. The dinB gene is one of the DNA-damage-induced genes and the corresponding protein, DinB, is the founding member of a Pfam family with no known function. The protein contains a four-helix up-dow…
Experimental studies of pristine graphene devices currently rely on the fact that the graphene crystallites can be visible under optical microscopes when the underlying substrate is engineered to exhibit high contrast. Here, we present that graphene can be visualized not only on a dielectric substrate but also on a cr…
