It was found that hydrocarbon nanotubes (HCNTs) and nano-onions (HCNOs) (hereafter collectively referred to as HCNT(O)s) can be converted to carbon nanotubes (CNTs) and nano-onions (CNOs) (hereafter collectively referred to as CNT(O)s) upon prolonged sonication via hybrid CNT⊂HCNT and CNO⊂HCNO nanostructures as interm…

The anode-supported planar solid oxide fuel cell (SOFC) was fabricated by a cost-effective single step cofiring process using high shear compaction (HSC)™ anode substrate. The HSC™ process is a novel ceramic tape fabrication technique, which offers advantages in low-cost and high-volume production of the anode substra…

We show that for graphene with any finite asymmetry in the on-site energy between the two sublattices (Δ), the optical absorption edge is determined by the Δ. The universal conductance will be broken and the conductance near the band edge varies with frequency as 1/ω2. The onset conductance is σc=2σ0=πe2/2h, independe…

We have investigated the Si and O self-diffusion in stoichiometric and substoichiometric amorphous ${\text{SiO}}_{2}$ by means of molecular-dynamics simulations. The diffusivity and the migration energies at different Si concentrations are reported and the results in qualitative agreement with previous experimental an…

Abstract Oxygen‐related surface functional groups on diamond‐like carbon (DLC) films were derivatized with fluorine‐ and nitrogen‐related groups by the gas‐phase chemical derivatization (GCD) method, and the groups were analyzed quantitatively by X‐ray photoelectron spectroscopy (XPS). It is desirable that a derivatiz…

Achieving stable single-digit nanometer inverted domains in ferroelectric thin films is a fundamental issue that has remained a bottleneck for the development of ultrahigh density (>1 Tbit/in.2) probe-based memory devices using ferroelectric media. Here, we demonstrate that such domains remain stable only if th…

Carbon nanotubes in printed field emission arrays are known to be often damaged during field emission. A high-resolution transmission electron microscopy and Raman scattering spectra suggest that the degraded structure is mainly determined by electrical treatment conditions. A nonstationary alternating-current treatme…

The influence of water vapor in air on power generation characteristic of solid oxide fuel cells was analyzed by measuring cell voltage at a constant current density, as a function of water vapor concentration at 800°C and 1000°C. Cell voltage change was negligible at 1000°C, while considerable voltage drop was observ…

The chiral tris-monodentate imidazolinyl ligands 1 a-c exhibit a strong tendency to form the discrete, helical [2+3] nanocages 3 ([1(2).2(3)]) with tartaric acids 2. Circular dichroism (CD) spectra and theoretical calculations reveal that supramolecular handedness of capsulelike architectures is determined only by the…

Highly oriented Zn(NO 3 ) 2 ·6H 2 O nanotubes were grown on mica substrates based on an epitaxy mechanism. The Zn(NO 3 ) 2 ·6H 2 O nanotubes with rectangular cross-section were self-assembled on mica surfaces into large-area, interconnected hexagonal networks. Fast evaporation of the solvent was found to be crucial fo…

We present a microscopic model of the quantum paraelectric-ferroelectric phase transition with a focus on the influence of coupled fluctuating phonon modes. These may drive the continuous phase-transition first order through a metaelectric transition and furthermore stimulate the emergence of a textured phase that pre…

Polycrystalline Ca3−xMgxCo2−yMnyO6 (y∼1.0) samples are prepared in order to investigate the A-site doping effect of Ca3Co2−yMnyO6 (y∼1.0). Compared with Ca3Co2−yMnyO6 (y∼1.0), the ferroelectric polarization and Curie point of Ca3−xMgxCo2−yMnyO6 (y∼1.0) at the maximal doping x∼0.3 are significantly enhanced. The magnet…

It is shown by coarse-grained off-lattice Monte Carlo simulations that a geometrically induced frustration of the parallel arrangement of rigid achiral bolaform amphiphiles can cause chirality in self-assembled nanostructures. The amphiphilic molecules are represented as rigid linear chains of 8 equally sized hydropho…

We observe that the high-temperature δ-phase of Bi2O3 is stabilized to room temperature by the epitaxial growth of nanostructures onto either (001)-oriented SrTiO3 or (001)p-oriented DyScO3 single crystal substrates. In addition, the morphology can be controlled by the miscut of the substrate. Synchrotron x-ray scatte…

Organoclays or nanoclays have gained increased attention from industry as well as academia during the past 1 1 / 2 decades. These clays are prepared from natural clays which invariably have other minerals as impurities. It is of prime significance to remove impurities from organoclays which find applications in polyme…
