Toroidal multipoles are the subject of growing interest because of their unusual electromagnetic properties different from the electric and magnetic multipoles. In this paper, we present two new related classes of plasmonic metamaterial composed of purposely arranged of four U-shaped split ring resonators (SRRs) that…
The discovery of a flat two-dimensional crystal known as graphene has contradicted Landau-Peierls-Mermin-Wagner arguments that there is no stable flat form of such crystals. Here, we show that the "flat" shape of graphene arises due to a microscopic buckling at the smallest possible interatomic scale. We show that the…
Since the first report of mesoporous silica nanoparticles in 2001, many efforts have been made to develop them for biomedical applications. With the emergence of new designs and increasingly complex synthetic schemes, mesoporous silica nanoparticles have never been more promising. For this promise to be fulfilled, how…
Water near extended hydrophobic surfaces is like that at a liquid-vapor interface, where fluctuations in water density are substantially enhanced compared to those in bulk water. Here we use molecular simulations with specialized sampling techniques to show that water density fluctuations are similarly enhanced, even…
Novel SHG effective inorganic open-framework chalcohalides, Ba(3)AGa(5)Se(10)Cl(2) (A = Cs, Rb and K), have been synthesized by high temperature solid state reactions. These compounds crystallize in the tetragonal space group I ̅4 (No.82) with a = b = 8.7348(6) - 8.6341(7) Å, c = 15.697(3) - 15.644(2) Å, V = 1197.6(3)…
Graphite oxide (GO) is a lamellar substance with an ambiguous structure due to material complexity. Recently published GO-related studies employ only one out of several existing models to interpret the experimental data. Because the models are different, this leads to confusion in understanding the nature of the obser…
The use of plastic mulch in agriculture has increased dramatically in the last 10 years throughout the world. This increase is due to benefits such as increase in soil temperature, reduced weed pressure, moisture conservation, reduction of certain insect pests, higher crop yields, and more efficient use of soil nutrie…
The interfacial behavior of 2-Thiobenzylbenzimidazole (TBBI) between aluminium alloy AA 3003 and 1M hydrochloric acid solution was investigated by mass loss technique. Mass loss is concentration and temperature dependent. The influence of temperature has been studied in the absence and in presence of TBBI in the hydro…
Abstract Therapeutic radiopharmaceuticals are designed to deliver high doses of radiation to selected target organs or tissues with an aim of minimizing unwanted radiation to surrounding healthy tissue. In this work, [ tris (1,10-phenanthroline) [ 153 Sm]samarium(III)]trithiocyanate ( 153 Sm-TPTTC) was developed for p…
Compatibilized Cis-1,3-butadiene rubber (BR)/ethylene-vinyl acetate copolymer (EVA)/high-impact polystyrene (HIPS) thermoplastic blend vulcanizates (TPVs) were prepared by dynamic vulcanization, with TPVs being compatibilized by styrene-butadiene-styrene (SBS) block copolymer. The effects of SBS compatibilizer on mech…
Melt-textured superconducting samples of FeSe0.5Te0.5 were successfully prepared. The measured critical temperature was TC = 14.5 K. The Fe–Se–Te samples were composition and magnetically inhomogeneous, consisting of magnetic grains with diameters in the range 10–100 nm. Raman spectra were obtained at room temperature…
C(60) molecules assemble into close packing layer under the domination of the intermolecular interaction when deposited onto Pt(111)-supported FeO layer kept at 400 K. From corresponding high resolution scanning tunneling microscopy (STM) image, a kind of C(60) molecular orientational ordering stabilized by the interm…
The versatility of a novel scaling approach in quantifying the structure of model well-defined 3-arm star polyethylene molecules is presented. Many commercial polyethylenes have long side branches, and the nature and quantity of these branches varies widely among the various forms. For instance, low-density polyethyle…
Two new compounds, Cd1.16Zn2.34(AsO4)1.5(HAsO4)(H2AsO4)0.5 (1) and Cd0.74Mg2.76(AsO4)1.5(HAsO4)(H2AsO4)0.5 (2), have been prepared hydrothermally. Their crystal structures consist of chains of edge-sharing M1O4(OH0.5)2, M1aO4(OH0.5)2, M2O5(OH0.5), and M2aO5(OH0.5) octahedra (M1, M1a = Zn, Cd; M2, M2a = Zn for 1, and M…
We review the current understanding of stress-free, defect-driven deformations in thin sheets of nematic solids, from simple, isolated cone-forming +1 disclination defects to more complicated textures constructed from simple building-block domains. Further, by building from these textures we may investigate the effect…
Praseodymium-doped fluorogermanate 60PbGeO<sub>3</sub>-20PbF<sub>2</sub>-20CdF<sub>2</sub> nano-structured phosphors were synthesized by thermal treatment of precursor glasses. Luminescence features of praseodymium ions incorporated into low-phononenergy PbF<sub>2</sub> nanocrystals dispersed in the fluorogermanate gl…
Using aerosol deposition, 2‐2 layered structured magnetoelectric ( ME ) composites were fabricated. Almost fully dense, polycrystalline Pb ( Zr,Ti ) O 3 ‐based piezoelectric thick films with thickness of over 20 μm were fabricated on the sintered CoFe 2 O 4 ( CFO ) magnetostrictive ceramics. Although the sintered CFO…
Circular polarizers with left-handed helical metamaterials can transmit right-handed circularly polarized (RCP) light with few losses. But a certain amount of left-handed circularly polarized (LCP) light will occur in the transmitted light, which is the noise of the circular polarizer. Therefore, we defined the ratio…

STUDY DESIGN: Peroxide/Fenton transition-metal redox c…
A solution gate field effect transistor (SGFET) using an oxidised boron δ-doped channel on (111) diamond is presented for the first time. Employing an optimised plasma chemical vapour deposition (PECVD) recipe to deposit δ-layers, SGFETs show improved current-voltage (I-V) characteristics in comparison to previous sim…
