We have studied the effect of the lattice relaxation on the interface electronic structure of ${\text{LaTiO}}_{3}/{\text{SrTiO}}_{3}$, focusing in particular on the wedge-shaped potential, the interface sub-bands, and the orbital ordering, from density-functional calculations using the linearized augmented plane-wave…
In the nacre layer of the mollusk, proteins play an important role in regulating the morphology and lattice structure of calcium carbonate minerals. However, this process remains elusive due to the fact that we do not understand how protein sequences control the structure and morphology of biominerals. To take us a st…

The corrosion behavior of AISI 304 stainless steel (SS304) in a batch system of enriched artificial seawater (EASW) in the presence of a sulfate-reducing bacteria (SRB) species ( Desulfovibrio desulfuricans ATCC 27774) was investigated using analytical techniques including electrochemical impedance spectroscopy (EIS),…
Label-free detection of DNA molecules on chemically vapor-deposited diamond surfaces is achieved with spectroscopic ellipsometry in the infrared and vacuum ultraviolet range. This nondestructive method has the potential to yield information on the average orientation of single as well as double-stranded DNA molecules,…
In this article, a magnetron sputtering (MS) method is reported to prepare a nanocomposite of embedded silver nanoparticles in simultaneously polymerized, nonfouling polyethylene oxide (PEO) film. X-ray diffraction (XRD) shows that the silver nanoparticles had tunable growth in the preferential (111) facet, and transm…
The photoluminescence (PL), electrochemical, and electroluminescence (EL) properties of Eu(III) complexes, [Eu(cppo)(2)(tta)(3)] (1) and [Eu(cpo)(2)(tta)(3)] (2; TTA = 2-thenoyltrifluoroacetonate) with two carbazole-based phosphine oxide ligands, 9-[4-(diphenylphosphinoyl)phenyl]-9H-carbazole (CPPO) and 9-(diphenylpho…
Presented are thermal desorption spectroscopy (TDS) data of alcohol adsorption on single-wall carbon nanotubes (CNTs) supported on silica. The adsorption kinetics of methanol, ethanol, propanol, 2-propanol, butanol, pentanol, and hexanol have been studied. Multimass TDS confirms molecular adsorption/desorption with lo…
Using bicontinuous microemulsions as templates opens a new field for the design of novel structures and thus novel materials, but has significant challenges due to the very small composition and temperature windows in which microemulsions are bicontinuous. In previous work we had shown that we can take a ternary base…
There are few existing methods for the quantitative functionalization of surfaces, especially for polymeric substrates. We demonstrate that alkyne end-functional diblock copolymers can be used to provide precise areal densities of reactive functionality on both hard (e.g., glass and silicon oxide) and soft (i.e., poly…
Abstract Polyurethane composites filled with carbon fibers (CF) and carbon nanotubes (CNT) were prepared by mixing and injection molding, and its mechanical as well as their thermal properties were investigated. Dynamic mechanical analysis (DMA), thermogravimetry analysis (TGA), and thermal conductivity tests were don…
Abstract The aim of this investigation has been to use high performance thermoplastic matrices such as polyamides instead of the commonly used polyolefins to develop natural fiber composites for substituting glass fibers without renouncing to their mechanical properties. For this purpose, different natural fibers such…
We have extended the random walk numerical simulation (RWNS) method with exponential distribution of trap states so that disordered morphologies of metal-oxide nanostructures are taken into account. By using a stochastic cluster model we generate random packings of nanoparticles with texture parameters (porosity, roug…
Abstract Thermally induced polymerization of multifunctional methylmethacrylate POSS (MMA‐POSS) was studied in this work for preparation of polymer/POSS nanocomposites. The polymerization of MMA‐POSS could be promoted with benzoyl peroxide (BPO). Self‐assembly of POSS into a layer‐by‐layer structure in the MMA‐POSS po…
Abstract Cationic nanoclays were treated by ion exchange with various ionic liquids (ILs) containing cations and anions of different structure and/or molecular weight in order to investigate the effects of the IL structure and cation chain length on extent of clay dispersion, intercalation, and thermal stability. The…
We report electron-paramagnetic resonance (EPR) studies at $\ensuremath{\sim}9.5\text{ }\text{GHz}$ ($X$ band) and $\ensuremath{\sim}34\text{ }\text{GHz}$ ($Q$ band) of powder and single-crystal samples of the compound ${\text{Cu}}_{2}{[\text{TzTs}]}_{4}$ [$N$-thiazol-2-yl-toluenesulfonamidatecopper(II)], ${\text{C}}_…
It is shown analytically that the output of the standard model for complex, nonlocal hysteresis, the Preisach model, exhibits long-time tails under quite general conditions. For uncorrelated input signals the exponent of the algebraic output correlation decay is determined solely by the tails of the input and the Prei…
Abstract General garnet structure (Ia3d) is a forgiving host and can accommodate cations of varying sizes and valence states. Studies on highly yttrium doped alumina ceramics with Ca and Si contamination indicated that YAG precipitates in the ceramic had a propensity to allow simultaneous incorporation of small amount…
Graphene is a two-dimensional carbon material with a honeycomb lattice and Dirac-type low-energy spectrum. In a strong magnetic field, where Coulomb interactions dominate against disorder broadening, quantum Hall ferromagnetic states realize at integer fillings. Extending the quantum Hall ferromagnetism to the fractio…
Abstract The objective of this research was to investigate the probability of reinforcing Polyamide66 (PA66) with both micron‐sized and nanosized calcium carbonate (CaCO 3 ) particles. For this purpose, micron‐sized and nanosized CaCO 3 particles were used as fillers to prepare microcomposites (conventional composites…
