Abstract Poly(ethylene‐ co ‐vinyl acetate)/clay nanocomposite fibers were fabricated using electrospinning. The fiber diameters were controlled by varying the polymer/chloroform concentration, which resulted in fibers with diameters ranging from 1 to 15 μm. The clay concentration was varied from 0.35 to 6.6 wt %. Scan…
The effect of length-bidispersity on the stability of nematic, smectic and columnar phases of rod-like particles is studied in the perfect alignment limit using Onsager's second virial theory. The rod-like particles are modelled as hard cylinders of equal diameters (D) but different lengths (). Three different smectic…
Abstract The effect of crosslink density on the pressure‐volume‐temperature (PVT) behavior and on the pressure relaxation response for two polycyanurate networks is investigated using a custom‐built pressurizable dilatometer. Isobaric cooling measurements were made to obtain the pressure‐dependent glass transition tem…
Abstract In this paper we demonstrate filling of carbon nanotubes (CNTs) grown by chemical vapor deposition (CVD) directly on Si 3 N 4 TEM grids. The CNTs are synthesized at different growth temperatures T CVD providing different numbers of sidewalls and diameters. We characterize each step of the peapod synthesis and…
Abstract Fully exfoliated PS/clay nanocomposites were prepared via FRP in dispersion. Na‐MMT clay was pre‐modified using MPTMS before being used in a dispersion polymerization process. The objective of this study was to determine the impact of the clay concentrations on the monomer conversion, the polymer molecular we…
Abstract The effects of sulfate reducing bacteria (SRB) on cathodic protection (CP) of the Q235 steel in the soils have been studied by bacterial analyses, electrochemical impedance spectroscopy (EIS), scanning electron microscopy (SEM) and energy‐dispersive X‐ray analysis (EDX). The results showed that the pH value o…
Nanoparticles with innovative optical, chemical, and magnetic properties combined in a single nanoparticle may be useful as biosensors, targeting agents, and therapeutic agents in the biomedical field. This study describes new magnetic nanoparticles (MNPs) containing the fluorescent dye rhodamine isothiocyanate (RITC)…
Abstract We have adopted the dip‐pulling method and a thinning technique to obtain interpenetrating polymer network (IPN) thin films with suitable thickness and adhesive strength on Al substrates. X‐ray photoelectron spectroscopy (XPS) and attenuated total reflection infrared spectroscopy (ATR‐FTIR) were used to study…
The high temperature demixing/recombination phenomenon previously observed in Ca-substituted La(2)Mo(2)O(9) oxide ion conductors [A. Selmi et al., Solid State Ionics, 2006, 177, 3051; Eur. J. Inorg. Chem., 2008, 1813] has been visualised using scanning electron microscopy and EDX analysis. The demixed state appears as…
In the course of our synthesis of hybrid photochromic compounds, the unexpected new organic photochromic title compound, C(29)H(33)N(3)O(2), (I), was obtained. It is a derivative of the parent spirooxazine 1,3,3-trimethyl-6'-(piperidin-1-yl)spiro[indoline-2,3'-3'H-naphtho[2,1-b][1,4]oxazine], (II). The 2'-ethoxy group…
Abstract We use density functional theory to explore the implications of atomically precise patterning of graphene with monovacancies. We show that one‐dimensional tracks of vacancies can be used to turn graphene into a magnetic meta‐material with properties that can be flexibly varied by external factors such as dopi…
A novel chelatofore functionalized spiropyran of the 2-oxaindane series, namely 8-formyl-7-hydroxy-3',3'-dimethylspiro[2H-chromene-2,1'(3'H)-2-benzofuran], C(19)H(16)O(4), is reported. In the crystalline state, dimers are formed as a result of the pi-pi stacking of aromatic groups of the 2H-chromene part of the molecu…
The two-layer average structure of the high-temperature phase basic Co-rich decagonal ${\text{Al}}_{72.5}{\text{Co}}_{18.5}{\text{Ni}}_{9}$ was determined based on single-crystal x-ray diffraction data. The five-dimensional (5D) structure model was refined in the noncentrosymmetric 5D space group $P\overline{10}m2$ (1…
3DNALandscapes, located at: http://3DNAscapes.rutgers.edu, is a new database for exploring the conformational features of DNA. In contrast to most structural databases, which archive the Cartesian coordinates and/or derived parameters and images for individual structures, 3DNALandscapes enables searches of conformatio…
Abstract This study examined the surface morphological evolution of polycarbonate and acrylonitrile butadiene styrene (PC/ABS) irradiated with an Ar ion beam using an ion beam system. PC was not affected by the Ar ion beam treatment at a lower ion beam treatment times but the ABS portion formed a foam‐like nanostructu…
Structural, optical, and electric properties of Er 2 O 3 films obtained from Er 2 O 3 ceramic target by the method of vacuum electron-beam deposition on sapphire substrates have been investigated. Optical characteristics of the films are studied in the range from UV up to IR using techniques of absorption, reflection,…
Abstract Copper–polypyrrole composites were successfully produced with a dual plasma process. X‐ray photoelectron spectroscopy (XPS), X‐ray diffraction (XRD) and Fourier transform infrared spectroscopy (FT‐IR) were used to characterise the structural properties. Topological and electrochemical investigations were also…

The vaporization of Cr-rich volatile species from interconnector materials for high temperature solid oxide fuel cells (SOFCs) is considered to be a major source of degradation that limits the lifetime of planar SOFC systems (Fujita et al., 2004, “Prevention of SOFC Cathode Degradation in Contact With Cr-Containing Al…
Abstract Recently, SiC‐based ceramics have been found to exhibit corrosion damage patterns, which can only be explained by electrochemical processes. Therefore, the current work focusses on the electrochemical test procedures to determine the corrosion behaviour of solid state sintered silicon carbide (SSiC) ceramics…
