Abstract One‐dimensional (1D) nanostructures of TiO 2 are grown directly on transparent, conductive glass substrate using hydrothermal/solvothermal methods. When employed as a photoanode in photoelectrochemical cells, the vertically aligned TiO 2 nanorod array exhibits slower charge recombination at electrolyte interf…
Ceria has been the subject of thorough investigations, mainly because of its use as an active component of catalytic converters for the treatment of exhaust gases. However, ceria-based catalysts have also been developed for different applications in organic chemistry. The redox and acid-base properties of ceria, eithe…
We report a method for obtaining unity-order refractive index changes in the accumulation layer of a metal-oxide-semiconductor heterostructure with conducting oxide as the active material. Under applied field, carrier concentrations at the dielectric/conducting oxide interface increase from 1 x 10(21)/cm(3) to 2.8 x 1…
The 11B NMR spectrum and relaxation processes in BiB3O6 crystals were investigated by determining the spin–lattice relaxation rates, 1/T1, of 11B NMR. The 11B spectrum obtained at room temperature indicates the presence of two types of chemically inequivalent 11B nuclei, designated B(1) and B(2). The relaxation rates…
Metal and semiconductor nanorods polarized by an external electric field tend to align parallel to this field. We derived the equation of motion for this alignment, taking into account electrostatic forces, thermal fluctuations and viscous resistance of the liquid the nanorods are suspended in. It was solved for a str…
Oscillatory surface-density profiles (layers) have previously been reported in several metallic liquids, one dielectric liquid, and in computer simulations of dielectric liquids. We have now seen surface layers in two other dielectric liquids, pentaphenyl trimethyl trisiloxane, and pentavinyl pentamethyl cyclopentasil…
Various one-dimensional (1D) ZnO-based nanostructures, including ZnO nano-wires (NWs) grown using vapour–liquid–solid (VLS) process, ZnO/ZnSe core/shell, nitrogen-doped ZnO and ZnMgO NWs were grown by metalorganic chemical vapour deposition (MOCVD). Transmission electron microscopy (TEM) analysis is presented. For all…
In this study, the effect of the fraction of transformed carbon layer on the tribological properties has been investigated. The fraction of transformed carbon layer was controlled by varying the reaction temperature of the hydrogen. The degree of the transformed carbon layer was measured using energy dispersive X-ray…
Abstract Native and nucleated PHB has been melt‐spun and the properties of the resulting fibers have been investigated. Biocompatible nucleating agents such as HAP and THY were compared to BN as a reference material. DSC was used to investigate the non‐isothermal crystallization kinetics as a function of processing te…
Two different enzyme applications were applied to black spruce thermomechanical pulping (TMP) in an attempt to selectively enhance the physical properties of the resulting pulp. Past studies have revealed some application difficulties between pulp and enzymes. A new method of enzyme application including fiberizing th…
<b>First book on rubber used as a construction material dedicated to the chemical process industry</b> Despite the long history of rubber as a construction material, this book is a unique publication as it comprehensively looks at the material with respect to the anti-corrosion requirements of the multitude of industr…
The aim of this work is to clarify the interaction mechanisms between the drilling tool and material.Among the defects caused by drilling, delamination appears as to be of the most critical and may occurs at both the entrance and exit plane.This paper presents a prediction Hocheng-Dharan model of thrust force for dril…
Site-specific configurations of Fe 3d electrons in a spinel ferrite were investigated by electron energy loss spectroscopy under electron channeling conditions. Site-specific spectra were extracted by applying a multivariate curve resolution (MCR) technique to the data set. An electronic difference in the Fe sites cau…
The role of specific cleavage of transcription repressor proteins by proteases and how this may be related to the emerging theme of dinucleotides as cellular signaling molecules is poorly characterized. The transcription repressor NmrA of Aspergillus nidulans discriminates between oxidized and reduced dinucleotides, h…
The c-axis transport properties of a high-pressure synthesized PrFeAsO0.7 single crystal are studied using s-shaped junctions. Resistivity anisotropy of about 120 detected at 50 K shows the presence of strong anisotropy in the electronic states. The obtained critical current density for the c-axis of 2.9×105 A/cm2 is…
Measurements with a scanning probe microscope sensitive to micron-scale magnetization variations provide evidence for stripes of enhanced superfluid density at the surface of an iron-pnictide superconductor.
The performance of phase change memory (PCM) cell, based on Ge2Sb2Te5, was significantly improved by using a CeO2 buffer layer. The presence of a buffer layer remarkably reduced the reset voltage of the PCM cell. Even at voltage pulse width of 10 ns, the buffered PCM cell could accomplish reset operation. Theoretical…
Atomically resolved scanning tunneling microscopy was conducted on cleaved single crystals of the cubic perovskite Pr0.68Pb0.32MnO3. Several different surface configurations could be resolved including a frequent square arrangement with atomic distances in excellent agreement to the bulk lattice constant of the cubic…
We have studied the evolution of cellular structures in Ge 1-x Si x single-crystal growth as a function of process parameters. Because these structures are much larger than those occurring during the solidification of metals, we developed a modified phase-field method, which is able to handle these structure within re…
A reproducible quasi-three-dimensional structure, composed of top and bottom concentric nanorings with same periodicity but different widths and no overlapping at the perpendicular direction, is built up by a separation-layer method, which results in huge enhancement of surface-enhanced Raman spectroscopy (SERS) due t…
