Inorganic semiconducting ZnOS nano material were doped in the pure Ferroelectric Liquid Crystal and electro-optic as well as dielectric properties have been scrutinized to understand the nature of ferroelectric liquid crystal nano material composite system (FLCNMCS). The nano material changes the characteristics of pu…
A modified gel-casting technique was used to fabricate a 1-3 piezoelectric ceramic/polymer composite substrate formed by irregular-shaped pillar arrays of small dimensions and kerfs. This technique involves the polymerization of aqueous piezoelectric (PZT) suspensions with added water-soluble epoxy resin and polyamine…
Abstract Considering that the sound velocity of concrete is lower than that of metal, this study discusses the effect of stationary shocks and compression during the process of shaped charge jet penetration into concrete when the penetration velocity is greater than sound velocity. The linear relationship between shoc…
Improving the energy storage capability of batteries and capacitors is inherently dependent on clarifying our understanding of ion dynamics of advanced electrolytes in a variety of materials. Herein we report a new attenuated total reflectance–surface-enhanced infrared absorption spectroscopy technique that can select…
In semiconductors, an absorbed photon can generate multiple electron-hole pairs, but measurements of this carrier multiplication efficiency in nanocrystals need to correctly account for charged excitons. Xiaoet al.meet this need by measuring energy transfer of biexcitons from nanocrystals to acceptor dyes. Carrier mul…
We demonstrated for the first time enhanced formation of polymers on nanostructures under X-ray irradiation. Surface enhanced Raman spectroscopy (SERS) using silver core–gold shell nanocoreshells (Ag@Au NCSs) as the SERS substrate was employed to quantify the amount of polymers on the surface. The yield of surface-gro…
Nonsurface-treated zinc oxide (ZnO) Schottky diodes were fabricated on a Si substrate using one of two different seed layers, prepared by either the sol-gel or hydrothermal method. Then, ZnO film was grown on a seed layer by the hydrothermal method, and Au/ZnO Schottky diodes were fabricated to study the effects of di…
Abstract A formula to predict the radial distribution of the fragment velocities of the Velocity Enhanced Warhead (VEW) is proposed. Not only the maximum velocity gains, but also the velocity gains with azimuth angle can be calculated using this formula. Its predictions are in good agreement with the experimental data…
The growth front of isotactic polypropylene (iPP) spherulites is studied with series of in-situ microanalyzing techniques: conventional source infrared microspectroscopic (CS-μIR), polarized infrared microspectroscopic imaging (SR-μPIR), and scanning X-ray microdiffraction (SR-μSXRD). By SR-μSXRD, the actual growth fr…
Abstract Titanium dioxide (TiO 2 ) thin films were deposited by remote‐plasma atomic layer deposition (RPALD). The process window was determined in the range from 150 to 300 °C for atomic layer deposition of TiO 2 thin film. The crystal structure and grain size of the TiO 2 thin films deposited by RPALD was controlled…
Thermodynamic stabilities of the phases of Sr–Si–N–O system were evaluated by simulating phase diagrams at various conditions based on first-principles density functional theory calculations. Synthesis conditions and stability of the compounds belonging to the system, in which oxidation and nitridation reactions are i…
Colloidal gold nanoparticles represent technological building blocks which are easy to fabricate while keeping full control of their shape and dimensions. Here, we report on a simple two-step maskless process to assemble gold nanoparticles from a water colloidal solution at specific sites of a silicon surface. First,…
Smectic liquid crystals with ‘de Vries-like’ properties are characterized by a maximum layer contraction of ≤1% upon transition from the non-tilted SmA phase to the tilted SmC phase. To expand the current library of ‘de Vries-like’ liquid crystals, we have developed a rational design strategy based on a concept of fru…
Colloid particles that are partially wetted by two immiscible fluids can become confined to fluid-fluid interfaces. At sufficiently high volume fractions, the colloids may jam and the interface may crystallize. The fluids together with the interfacial colloids form an emulsion with interesting material properties and…
Abstract Two‐dimensional (2D) CuO nanosheets were fabricated on Cu foils using a solution method. The method was novel, easy and can be completed at room temperature in the absence of any surfactant. The obtained materials were characterized by X‐ray diffraction (XRD), X‐ray Photoelectron Spectroscopy (XPS), scanning…
Show me inside: 3D time-of-flight secondary-ion mass spectrometry (TOF-SIMS) with a dual-beam mode allows the detection of the characteristic biopolymers from surface to subsurface in plant cell walls. Lateral and vertical distribution of major components can thereby be mapped to understand the structural architecture…
Recent experimental literature (Sol. Energ. Mat. Sol. Cells, 2012, 105, 192) has reported that nitrogen doped Cu2O is a possible material for novel intermediate band solar cells. The doping effects of nitrogen on the crystal structure, electronic structure, and optical properties of Cu2O have been studied by an ultras…
Solubility of 2-hydroxybenzoic acid (salicylic acid, with measured melting point of 432 K) in water, 1-propanol, 2-propanol, and 2-propanone was determined at (298.2 to 338.2) K and atmospheric pressure. Also, the solubility of salicylic acid in binary mixtures of 1-propanol (1) + water (2), 2-propanol (1) + water (2)…
Abstract Dedicated to Professor François Diederich on the occasion of his 60th birthday
The best performance of the phosphor Li(2)SrSiO(4): Eu(2+), Ce(3+) in terms of luminescence efficiency (LE), color rendering index (CRI) and color temperature (Tc) for light-emitting diode application was optimized with combinatorial approach. The combinatorial libraries were synthesized with solution-based method and…
