We propose a hyperbolic metamaterial waveguide to realize a highly efficient rainbow trapping effect, which can be used to develop practical on-chip optical super absorbers with a tunable absorption band.
Tetrathiafulvalene (TTF) derivatives TTF-Bor, TTF-2UM and TTF-4UM having chiral urethane groups were prepared. Among them, TTF-2UM, TTF-4UM and their charge-transfer (CT) complexes with F4TCNQ organized the nanowires. The intermolecular hydrogen bonding of the chiral urethane groups and π-stacking of TTF moieties or t…
Nanocrystalline M-type Co2+ substituted barium hexaferrites samples having generic formula barium Ba0.5Sr0.5Fe12-xCoxO19 (x=0.0, 0.2, 0.4, 0.6, 0.8 and 1.0) were synthesized by chemical co-precipitation method. The sintered samples were characterized by XRD, SEM and VSM techniques. All the XRD patterns showed the sing…
Using MM3 force-field simulations in combination with optical measurements, we investigate the morphology and dispersion of a variety of single-walled carbon nanotubes (SWNTs) non-covalently functionalized by carbazole polymers. Our results elucidate that isomer types of poly-carbazoles together with their length gove…
Using density functional theory calculations, we show that recently synthesized carbon nanocomposites of graphene nanoribbons encapsulated in a carbon nanotube (GNR@CNT) possess rich emergent electronic and magnetic properties that offer new functionality and tunability and display systematic trends that are sensitive…
Specific conductivity of the composite nanomaterial layers with micron and submicron dimensions, consisting of carboxymethyl cellulose (CMC) and multiwalled carbon nanotubes (MWCNT) was investigated. Ultradispersed aqueous suspension was deposited on soft (aluminum foil, plates made from polyester and polyimide, cotto…
Mechanically driven glassy systems and complex fluids exhibit a wealth of rheological behaviors that call for theoretical understanding and predictive modeling. A distinct feature of these nonequilibrium systems is their dynamically evolving state of structural disorder, which determines their rheological responses. H…
The suprafibrillar organisation of collagen rich tissues is the keystone to the diversity of resultant structures made from relatively similar materials. The local organisation between fibrils may be essential to suprafibril structures that are critical to functionality such as transparency in cornea, where specific l…
The applications of powder cores to very high power conversion equipment have recently been spreading. Fe-Si alloys are effective in downsizing magnetic cores because they have large degrees of magnetization. However, core loss needs to be further reduced. The relationships between core losses for Fe-3mass%Si powder c…
A porous oxohalide, Fe6Ca2(SeO3)9Cl4, has been synthesized by solid state reactions using concentrated HCl as the Cl-source. It crystallizes in the hexagonal space group P63/m with unit cell parameters a = 12.118(2) Å, c = 12.703(4) Å, Z = 2. The crystal structure is an open framework having one-dimensional channels e…
A new synthetic approach is developed and nine distinct organic functionalized oxomolybdenum complexes, 1–9, are synthesized and fully characterized. Specifically by altering the functional groups on imidazoles we succeeded in making a series of crystalline structures with unique underlying topologies and/or functiona…
Here we report on the study of vertical alignment of a nematic liquid crystal due to the segregation between perfluorinated and the polysiloxane groups of a multi-component composite alignment material. The measured surface anchoring energy was found to depend on the relative amount of polysiloxane matrix in the compo…

An epoxy-group-containing vinyl monomer, glycidyl methacrylate, was graft-polymerized onto an electron-beam-irradiated porous sheet to form a graft chain. Graft chains can be categorized according to the formation site into the polymer brush extending from the pore surface of a porous sheet and polymer root penetratin…
A facile method was developed to synthesize Al(OH) 3 nanostructures from Al(OH) 3 microagglomerates by dissolution in 9.0 mol·L −1 NaOH at 115°C followed by dilution and aging of the solution at room temperature. The influence of Al(OH) 3 nanoseed and surfactants as sodium dodecyl sulfate (SDS), polyethylene glycol 60…
An silica supported chitosan-Schiff base Pd(II) catalyst was prepared in a simple way and characterized by XRD, FT-IR, SEM-EDS, XPS and TG, and the ability of this complex to catalyze hydrogenolysis of 1-tetralone into 1,2,3,4-tetrahydronaphthalene was also investigated in the presence of hydrogen. It has been reveale…

Heterogeneous media constitute random disordered environments where transport is drastically hindered. Employing extensive molecular dynamics simulations, we investigate the spatio-temporal dynamics of tracer particles in the Lorentz model in the vicinity of the localization transition. There transport becomes anomalo…
An ultrathin, wideband, polarization-insensitive and wide-angle metamaterial absorber is presented, which is based on one order Minkowski fractal double square loop (MFDSL) electric resonator structure and resistance film. The unit cell of this absorber consists of MFDSL, square resistance film, dielectric substrate a…
The phase equilibria in the quasi-ternary system Tl 2 Se-HgSe-GeSe 2 were investigated by differential-thermal analysis and X-ray diffraction. Phase diagrams of the Tl 2 Se-HgSe and Tl 2 GeSe 3 -HgSe systems were constructed, as well as the isothermal section of the Tl 2 Se-HgSe-GeSe 2 system at 520 K. Two intermediat…
