In this paper, a novel strategy for the one step synthesis of the carbon nanotube/gold (MWCNT−Au) nanocomposites to obtain a well-defined conductive nanomaterial has been explored and incorporated into the electrochemical system to facilitate the electron exchange between the electrode and the electrochemical probe.
A hierarchical procedure bridging the gap between atomistic and mesoscopic simulation for polymer-clay nanocomposite (PCN) design is presented. The dissipative particle dynamics (DPD) is adopted as the mesoscopic simulation technique, and the interaction parameters of the mesoscopic model are estimated by mapping the…
The potential solid oxide fuel cell anode material Sr 2 MgMoO 6 adopts a √2 × √2 × 2 I1̄ superstructure of the simple perovskite cell, derived from an a 0 a 0 c - tilt system via distortion of the Mg- and Mo-centered octahedra. Reduction of Sr 2 MgMoO 6 appears to be correlated with antisite disorder at either point o…
The synthesis, structural characterization, and magnetic properties of crystalline manganese oxide nanoparticles are presented. The procedure is based on the reaction of benzyl alcohol with the two precursors: potassium permanganate KMnO 4 and manganese(II) acetylacetonate Mn(acac) 2 . Depending on the precursor used,…
A novel method for preparing an acellular xenogeneic extracellular matrix scaffold for tissue engineering was developed. Bovine vocal fold lamina propria specimens were treated with high-concentration sodium chloride, nucleic acid digestion, and ethanol dehydration for decellularization and removal of immunogenic fore…
A simple model for the autolocalization of a free charged particle is presented. The polarization well in the model is deep enough for only one localized level. In dielectric materials with a sufficiently large dielectric constant, two charged identical particles can be localized in one polarization potential well, fo…
Molecular dynamics simulation study based on the EAM potential is carried out to investigate the effect of pressure on the rapid solidification of Aluminum. The radial distribution function is used to characterize the structure of the Al solidified under different pressures. It is indicated that a high pressure leads…
This article describes the aqueous atom transfer radical polymerization synthesis of poly(3-sulfopropylmethacrylate) brushes onto gold and Si/SiO2 surfaces in a controlled manner. The effect of Cu(I)/Cu(II) ratio was examined, and a quartz crystal microbalance was used to study the kinetics of the brush synthesis. The…
Novel systems of layered graphene are attracting interest for theories and applications. The stability, band structures of few-layer graphite films, and their dependence on electric field applied along the c-axis are examined within the density functional theory. We predict that those of Bernal type and also rhombohed…
Square porphyrin nanosheets with uniform thickness (7−12 nm) and aspect ratios up to 100 have been synthesized for the first time using a reprecipitation method. They retain the photocatalytic activity of the precursor molecules and can be self-metallized with Pt, Pd, and Au. Their unique morphology, photocatalytic pr…
Measurements of magnetic noise emanating from ferromagnets due to domain motion were first carried out nearly 100 years ago and have underpinned much science and technology. Antiferromagnets, which carry no net external magnetic dipole moment, yet have a periodic arrangement of the electron spins extending over macros…
The anisotropic broadening of ZrSiO4 sample is modelled using the Stephens's phenomenological model for anisotropic line broadening and the three dimensional strain distribution in the sample is plotted. The micro-structural parameters like domain size and dislocation density are estimated using the variance method.
We investigate short rane order in liquid and supercooled liquid Fe and Fe-based metallic glass using ab-initio simulation methods. We analyze the data to quantify the degree of local icosahedral and polytetrahedral order and to understand the role of alloying in controlling the degree of geometric frustration . Compa…
The goal of the current study was to find the quantitative relationship between electrospun polycaprolactone scaffold fiber diameter and NIH 3T3 fibroblast adhesion and growth kinetics. By varying 3 important process parameters--solution concentration, voltage, and collector screen distance--different average fiber di…

Abstract This article is a brief summary of the ISO Standard 20903. This standard provides information on methods for the measurement of peak intensities in Auger electron and X‐ray photoelectron spectra and on uncertainties of the derived peak areas. It also specifies the necessary information required in a report of…
High Resolution Image Download MS PowerPoint Slide We have demonstrated a simple and convenient method for fabricating the nanorod arrays of the organic charge-transfer complex of κ-(BEDT-TTF) 2 Cu(SCN) 2 supported on Pt foil and ITO glass. The morphologies of the κ-(BEDT-TTF) 2 Cu(SCN) 2 nanorod arrays can be control…
Mesoporous molecular sieves, MCM‐41, were synthesized from sepiolite using acid leaching, followed by hydrothermal reconstruction and then calcinations at 540°C for 5 h. The structures and the porosity of MCM‐41 were investigated by means of small‐angle X‐ray diffraction patterns, Brunaer‐Emmett‐Teller (BET), 29 Si MA…
Allylthiourea cadmium chloride , a promising non-linear optical material was grown from aqueous solution by slow evaporation technique. Single crystal X-ray diffraction studies reveal that the crystal is trigonal structure with R 3 C space group. The spectroscopic properties were investigated by recording the Fourier…
