Plant oils are already one of the most important platform chemicals for the chemical industry due to its universal availability, inherent biodegradability, and low price. Nowadays, plant oils are already a commercial source of multifunctional monomers and oligomers for polyurethane synthesis, and the design of novel b…
We achieve tunneling spin injection from Co into single layer graphene (SLG) using TiO₂ seeded MgO barriers. A nonlocal magnetoresistance (ΔR(NL)) of 130 Ω is observed at room temperature, which is the largest value observed in any material. Investigating ΔR(NL) vs SLG conductivity from the transparent to the tunnelin…
Tb<sup>3+</sup>-doped Lu<sub>3</sub>Al<sub>5</sub>O<sub>12</sub>(hereinafter referred to as LuAG:Tb) films were successfully prepared by Pechini sol-gel process and spin-coating technique on carefully cleaned (111) silicon wafer. The microstructure and optical properties of the LuAG:Tb films were studied by X-ray diff…
This paper describes a novel remote plasma sputtering technique for depositing optical thin films. This technology is based on generating intensive plasma remotely from the target and then magnetically steering the plasma to the target to realize the sputter deposition. It overcomes several of inherent limitations in…
YBCO films were grown on CeO<sub>2</sub>/YSZ/CeO<sub>2</sub> buffered rolling-assisted biaxially textured substrates (RABiTS) by pulsed lased deposition (PLD). CeO<sub>2</sub> cap layer was deposited prior to YBCO growth. CeO<sub>2</sub> cap layers of different thickness were prepared to evaluate the thickness depende…
In order to obtain the deformation grain structure for static recrystallization,an initial grain structure are produced by lattice deformation model;aiming at characteristics of different deformation regions and non-uniform distribution of the stored energy in deformed alloy,a multistate free energy(MSFE) function are…
The inrush current occurs during transformer energization due to flux saturation in the core. Controlled switching connects transformer to power grid in proper phase angle derived from core remanent fluxes. The DC forced magnetization prior to transformer energization is one of simultaneous closing strategy methods. A…
The measurement of the energy loss spectra of energetic electrons scattered from Xe over large angles is reported. The incoming energy was chosen between 600 eV and 1550 eV. The calculated Xe elastic scattering cross section has a sharp minimum for 750 eV electrons near 135°. This minimum is confirmed by studying a Xe…
The process of attachment of a deformable polystyrene colloidal particle to a planar substrate shows features of slow relaxation and aging, typically observed in many-body disordered and glassy systems. This slow dynamics is attributed to the presence of polymeric tethers constituting a few internal degrees of freedom…
Porphyrine mögen verwirrt sein, aber nicht Linus Pauling oder Melvin Calvin – Calvin schlug 1943 „Carboporphyrine“ vor, und Pauling, dessen Portrait hier gezeigt ist, untersuchte 1944 die Existenz und Stabilität solch fundamentaler Porphyrine. Was er „Isoporphyrine“ mit „extrovertierten Pyrrolringen“ nannte, wird heut…
A hierarchically structured carbon replica with a tri-modal distribution of porosity was prepared by pyrolysis of a three-dimensionally ordered macroporous (3-DOM) organic–inorganic hybrid layered double hydroxide (LDH). By an original inverse opal method involving LDH platelet regeneration, macroporous Mg2Al–vinyl be…
In a recent article [J. Opt. Soc. Am. A27, 1694 (2010)], we proposed a rectangular truncation method to mitigate the convergence problems arising from the boundary matching conditions of a binary metallic grating. The proposed method may underestimate the total power in the scattered field for certain grating paramete…
Quasicrystals are fascinating intermetallic compounds composed of two or more elements. They differ from conventional crystals in that they possess long-range order, but no translational symmetry--that is, they are aperiodic. Much effort has been expended on identifying routes towards exploiting and exploring the prop…
We report on the investigation of magnetic field induced charge density waves and Hall coefficient sign reversal in a quasi-two-dimensional electronic system of highly oriented pyrolytic graphite under very strong magnetic field. The change of Hall sign coefficient from negative to positive occurs at low temperature a…
Accurate simulations of Green's function and the self-energy function for noninteracting electrons in disordered graphenes are performed. The fundamental physical quantities such as the elastic relaxation time ${\ensuremath{\tau}}_{e}$, the phase velocity ${v}_{p}$, and the group velocity ${v}_{g}$ are evaluated. New…
We study two problems in the framework of the integral equation theory of polymer-mediated spatial organization of nanoparticles in dense melts motivated by multiscale simulation and many body physics issues. How nonspherical nanoparticle shape modifies polymer-induced interactions under dilute nanoparticle conditions…
Abstract The effect of repetitive processing on the mechanical properties and fracture toughness of dynamically vulcanized isotactic polypropylene/ethylene‐propylene‐diene rubber blends (TPVs) with and without addition of β‐nucleating agent (β‐NA) was studied. The results showed that the repetitive processing did not…
A topographical study on an ensemble of height profiles obtained from atomic force microscopy techniques on various independently grown samples of tungsten oxide WO3 is presented by using ideas from percolation theory. We find that a continuous “geometrical” phase transition occurs at a certain critical level-height δ…
Control of the crystallographic orientation of nanocrystal facets is widely recognized to be a key prerequisite for the synthesis of highly efficient nanocrystal-based catalysts. Here, we demonstrate that the facet evolution during the synthesis of gold nanocrystals can effectively be controlled by the addition of aux…
Carbon nanotubes are extremely sensitive to the molecular species in the environment and hence require a proper passivation technique to isolate them against environmental variations for the realization of reliable nanoelectronic devices. In this paper, we demonstrate a parylene-C passivation approach for CNT thin fil…
