The surface roughness of thin amorphous films of chalcogenide glasses (ChG) after photostimulated dissolution in amine-based selective etchant has been investigated. It is established that the rms roughness of the annealed and photoetched ChG film substantially smaller than the as-evaporated film and etched in the sam…
In the fabrication of bit-patterned media (BPM), two processes are commonly used, i.e., the pattern transfer by ion-milling into an underlying film of magnetic material, and the direct deposition of the magnetic material onto a pre-patterned substrate. We experimentally compared the switching performance of the BPM ba…
We have investigated electrical transport properties of long (>10 μm) multiwalled carbon nanotubes (NTs) by dividing individuals into several segments of identical length. Each segment has different resistance because of the random distribution of defect density in an NT and is corroborated by Raman studies. Higher is…
OBJECTIVE: To perform a topographical characterization of a titanium alloy subjected to different surface treatments using roughness evaluation, scanning electron microscopy, and atomic force microscopy. MATERIALS AND METHODS: For each group, 6 discs of a titanium alloy had their surfaces modified by 4 treatments. All…
We report current-driven crystallization in a TiSi3/Ge2Sb2Te5/TiN vertical cell, which can be well controlled and is expected to be applied to multilevel storage with a low threshold voltage of about 1 V. We demonstrate that the number of distinct resistance levels can readily reach 8 and even higher. These levels in…
A Bayesian technique to correct for Poisson noise in one-dimensional data, such as X-ray/neutron scattering curves, is presented. This `denoising' method calculates a probability for any given curve to be the true underlying signal and generates the curves having the highest probabilities. Gaussian processes with a no…
We investigate the azimuthal dependence of the switching field strength for nematic liquid crystal bistability on patterned alignment layers to determine the validity of a switching theory proposed by Kim et al. [Appl. Phys. Lett. 78, 3055 (2001)] and to evaluate higher-order azimuthal anchoring coefficients. Director…
Abstract Thermoelectric (TE) InGaZnO thin films grown on sapphire substrates by sputtering were optimized using a radio‐frequency (RF) argon plasma treatment. The oxide thin films exhibited layered InGaO 3 (ZnO) 2 superlattices with excellent crystallinity by using ZnO buffer layers and a post‐annealing process at 900…
The understanding of the formation of graphene at the atomic scale on Si-terminated 3C-SiC for obtaining high-quality graphene sheets remains elusive, although epitaxial graphene growth has been shown to be a well-known method for economical mass production of graphene/SiC heterojunctions. In this paper, the atomic be…
The electric transport properties of diazonium functionalized graphene (DFG) were investigated. The temperature dependence of the resistivity (ρ-T) and the Shubnikov-de Haas oscillation of the DFG revealed two-dimensional hole gas (2DHG) behaviors. The DFGs exhibited unusual weak localization behaviors in which both i…

Tissue engineering provides a new strategy for repairing damaged cartilage. Surface and mechanical properties of scaffolds play important roles in inducing cell growth. AimThe aim of this study was to fabricate and characterize PLGA and gelatin/hyaluronic acid-treated PLGA (PLGA-GH) sponge scaffolds for articular cart…
In this Article the ion exchange equilibrium of binary and multicomponent systems was modeled with homogeneous mass action law using activities and taking account of the partial dissociation of salts according to Kester and Pytkowicz's approach. The activity coefficients in the solution were estimated by the Pitzer mo…
Micro- and nanowires are commonly used in biological sciences, micro- and nanoelectronics, and optoelectronics, and their morphological stability needs to be understood and controlled. Previous linear-stability analyses of infinitely-long circular wires have shown that the critical wavelength for instability approache…
We report a novel method for high-throughput investigations on cell-material interactions based on metal oxide nanoscaffolds. These scaffolds possess a continuous gradient of various titanium alloys allowing the compositional and morphological variation that could substantially improve the formation of an osseointegra…
Abstract In this work, β‐polypropylene/polystyrene (β‐PP/PS) blends were prepared with PP, PS, and a novel supported β‐nucleating agent or β‐nucleated PP and PS. The β‐PP/PS blends were compatabilized by PP‐g‐MA, PP‐g‐GMA, POE‐g‐MA, and EVA‐g‐MA, respectively. For exploring the effect of PS amount and compatibilizers…

Abstract A functionalized fumed silica was dispersed in water using a nonionic surfactant, yielding a stable nanodispersion. This was blended with an aqueous acrylic polymer dispersion to produce hybrid nanocomposite films. The silica particles were shown to be well dispersed in the polymer matrix, with little agglome…
First-principles calculations were employed to investigate the electronic properties and formation energy of Cl-related complex defects, with either carbon (silicon) vacancies, VC (VSi) or dopants (nitrogen/aluminum). Our investigation revealed that Cl at a Si-site related complexes, such as the ClSiVC and ClSiNC, are…
