Molybdenum oxide (MoOx) has been shown to act as an efficient hole extraction layer in organic photovoltaic (OPV) devices. However, exposing MoOx films to air is problematic as it is hygroscopic; the uptake of moisture having a negative impact on its electronic properties. Here, we use spectroscopic ellipsometry to ch…
ZrB${}_{2}$ is a nonsuperconducting Pauli paramagnetic crystallizing in the AlB${}_{2}$ structure. V substitution for Zr in Zr${}_{1\ensuremath{-}x}$V${}_{x}$B${}_{2}$ (0.01 $\ensuremath{\le}$ $x$ $\ensuremath{\le}$ 0.1) at the few percentage level induces superconductivity with critical temperature reaching a maximum…
Unüberbrückbare Differenzen: Das elektronenreiche Diacetondiperoxid wechselwirkt mit den elektronenarmen Ringen von Trichlor- und Tribromtrinitrobenzol unter Bildung energiereicher Cokristalle. Obwohl beide Cokristalle isostrukturell sind, ist erstgenannter sehr stabil, während letzterer eine seltene Metastabilität au…
In this paper, we propose a physical method to manipulate the ice crystallization by applying an AC electric field during the liquid-solid transition of 0.9 wt. % NaCl aqueous solution. By using optical microscopic observation, we found that the ice grains are miniaturized in the presence of AC electric field during f…
Active packaging is utilized to overcome limitations of traditional processing to enhance the health, safety, economics, and shelf life of foods. Active packaging employs active components to interact with food constituents to give a desired effect. Herein we describe the development of an active package in which lact…
We demonstrate that the shape and the orientation of a surface plasmon (SP) vortex can be deterministically tailored through the geometrical design of a plasmonic Archimedes spiral (PAS). Noncircular SP vortices exhibiting “c,” triangular, and square patterns are successfully synthesized under circular polarized plane…
Magnetic iron oxide nanoparticles synthesized by coprecipitation and thermal decomposition yield largely monodisperse size distributions. The diameters of the coprecipitated particles measured by X-ray diffraction and transmission electron microscopy are between approximately 9 and 15 nm, whereas the diameters of ther…
Abstract A variety of Er3+‐, Tm3+‐, and Yb3+‐activated CaF2‐, SrF2‐, (Ca, Sr)F2‐ and (Sr, Ba)F2‐based fluoride laser ceramics have been prepared by the hot‐forming technique. Lasing of the SrF2:Yb3+, (Ca, Sr)F2:Er3+, (Ca, Sr)F2:Tm3+, (Ba, Sr)F2:Tm3+ and (Ba, Sr)F2:Yb3+ specimens with diode pumping has been observed fo…
A novel metal structure that integrates a continuous metal film and double deep subwavelength metal cylinder arrays standing on both surfaces is proposed. Near-perfect optical transmission is observed in this metal film structure due to the cooperative effects of the double deep subwavelength plasmonic arrays which, r…
Large ureter damages are difficult to reconstruct. Current techniques are complicated, difficult to perform, and often associated with failures. The ureter has never been regenerated thus far. Therefore the use of tissue engineering techniques for ureter reconstruction and regeneration seems to be a promising way to r…
The large-scale preparation of graphene is of great importance due to its potential applications in various fields. We report herein a simple method for the simultaneous exfoliation and reduction of graphene oxide (GO) to reduced GO (rGO) by using alkynyl-terminated dopamine as the reducing agent. The reaction was per…
In the past decade, there has been significant progress in the development of water soluble near-infrared fluorochromes for use in a wide range of imaging applications. Fluorochromes with high photo and thermal stability, sensitivity, adequate pharmacological properties and absorption/emission maxima within the near i…
Abstract The synthesis, structure and electrochemical properties of several silver‐containing liquid metal salts have been investigated. These ionic liquids comprise of a silver‐containing cation with a silver centre coordinated by two or more alkylamine ligands and a bis(trifluoromethylsulfonyl)imide (Tf2N) anion. Wi…
Utilizing the colorimetric and fluorogenic changes, a system based on polydiacetylenes (PDAs) is developed for the detection of neomycin. The PDA supramolecules polymerized from the mixed liposome composed of N-(3-hydroxyphenyl)pentacosa-10,12-diynamide (PCDA-AP) and pentacosa-10,12-diynoic acid (PCDA) at an optimized…
Plasmonic resonances (λres's) at the telecommunication wavelengths of 1.3 and 1.55 μm can be accurately produced in ZnO layers grown at 200 °C by pulsed laser deposition in pure Ar ambient using a ZnO target with 3 wt. % Ga2O3, and then annealed in air to produce Hall-effect-determined carrier concentrations 8.8 and 6…
Magic angle spinning solid-state NMR is a unique technique to study atomic-resolution structure of biomacromolecules which resist crystallization or are too large to study by solution NMR techniques. However, difficulties in obtaining sufficient number of long-range distance restraints using dipolar coupling based spe…
Mass-independent isotope fractionations driven by differences in volumes and shapes of nuclei (the field shift effect) are known in several elements and are likely to be found in more. All-electron relativistic electronic structure calculations can predict this effect but at present are computationally intensive and l…
Controlling the morphological structure of titanium dioxide ( TiO 2 ) is crucial for obtaining superior power conversion efficiency for dye‐sensitized solar cells. Although the sol–gel‐based process has been developed for this purpose, there has been limited success in resisting the aggregation of nanostructured TiO 2…
Abstract Uniformity of elements distribution in Cu2ZnSnS4 (CZTS) thin films were analyzed using X‐ray photoelectron spectroscopy (XPS) to improve of conversion efficiency on solar cells. The films were prepared from CuCl or CuCl2, ZnCl2, SnCl2, and thiourea by spray pyrolysis on quartz glass. The composition on surfac…
We advance a theory of ripple formation on the surface of an initially elemental material that is subjected to concurrent oblique-incidence impurity deposition and normal-incidence ion bombardment. The theory applies when the target atoms and impurities react to produce a chemical compound, as in many experiments that…
