Expressions are derived for additional contributions to the linear, quadratic, and cubic electric susceptibilities of molecular crystals that arise when molecules are displaced by the applied electric field. The contributions depend on quantities related to the infrared intensity of lattice vibrations, to the Raman in…
We have investigated the magnetic properties of polycrystalline Y bRu(2)(Ge(1 - x)Si(x))(2) samples using magnetic susceptibility, electrical resistivity, and specific heat measurements. All the results indicate that the Yb ions in Y bRu(2)(Ge(1 - x)Si(x))(2) are in a stable trivalent state. The antiferromagnetic orde…
Phase equilibria in the system U-Pd-B were established at 850 °C by light optical microscopy (LOM) and x-ray powder and single crystal diffraction. Whereas in as-cast alloys only one ternary compound, τ(1)-U(2 + x)Pd(21 - x)B(6), was found to form at x ∼ 0.5, a further compound τ(2) with hitherto unknown structure was…
In the title complex, {[Co(C(6)H(8)N(2)O(2))(C(9)H(7)NO(2))(H(2)O)(2)](ClO(4))(2)}(n), the Co(II) ion lies on an inversion centre and is coordinated in a slightly distorted octa-hedral environment. The 2,5-dimethyl-pyrazine 1,4-dioxide ligand, which also lies on an inversion center, acts as a bridging ligand, linking…
The particle removal efficiency (PRE) of cleaning processes diminishes whenever the minimum defect size for a specific technology node becomes smaller.For the sub-22 nm half-pitch (HP) node, it was demonstrated that exposure to high power megasonic up to 200 W/cm c did not damage 60 nm wide TaBN absorber lines corresp…
Relevant properties have been detected in protein fraction (LP) isolated from latex of Calotropis procera. In order to best characterize LP potentiality, this work describes some effects of LP on central nervous system (CNS). Three models were performed: elevated plus maze (EPM), open field (OF), and hole-board (HB) t…
Abstract From solid state reactions of Ag2O and Sb2O3 at high temperatures under elevated oxygen pressures a new silver antimonate, Ag3SbO4, has been obtained. The crystal structure of Ag3SbO4 was determined from powder data (P4122 (no. 91) with a = 7.0436(1), c = 8.8665(1) Å, V = 439.88(2) Å3, Z = 4, Rp = 8,75 %, Rwp…

Incorporating an efficient approach for the finite-element simulation of eddy current superconductive quantum interface device (SQUID) nondestructive evaluation (NDE) systems, an appropriate finite-element method (FEM) has been presented for simulating and analyzing such systems. We have introduced a new model for the…
Small angle neutron scattering is used to study the phase behavior of mixtures of two immiscible homopolymers (A and B) and a diblock copolymer (A−C) wherein B and C chains exhibit attractive interactions (negative Flory−Huggins interaction parameter) and the other pairs of chains exhibit repulsive interactions. This…
Viel Platz: Anionische tetraedrische Aggregate, gebildet durch Kombination von Cyclotricatechylen-Anionen mit Übergangsmetallionen wie Vanadium (siehe Bild), umschließen große Hohlräume, die Alkalimetallionen und Lösungsmittelmoleküle aufnehmen können. Anionische Einheiten mit geeigneten Metallzentren lassen sich zu h…
The National High Magnetic Field Laboratory (NHMFL) is designing two series-connected hybrid magnets, one for the Helmholtz Center Berlin (HZB) and the other for the NHMFL. The one for HZB has a horizontal, conical warm bore with a 30 degree opening angle for neutron scattering experiments. The one for the NHMFL has a…
A decrease in electron density and a strong increase of electron energy, which induce the enhancement of excitation rates, have been observed in CH 4 –CO 2 plasmas when the inlet methane concentration is high enough and the input microwave power sufficiently low. Together with the decrease in the electron density with…
Objective. To define the rate of bone tissue integration with porous implant and quantity of calcium and phosphorus in implants extracted in 4.5 months and 1.5 years after insertion. Material and Methods. Microstructure of specimens of porous titanium nickelide was examined by phase contrast. Chemical composition of s…
Structural cellular materials provide an important opportunity for the realisation of lightweight structures for transport applications. These materials have been extensively researched in the past, culminating in the classic text by Gibson and Ashby [1]. Such structural cellular materials include honeycomb and foams,…
This paper describes an approximate method for analyzing two-phase flow of gas and liquid water in fuel cell channels, whose surfaces are sufficiently hydrophilic for liquid water to wick spontaneously into the channel corners. This analysis is used to address the important question of whether the gas flow at typical…
The phase relations of the CeCo(9 + δ)Si(4 - δ) system have been studied by means of scanning electron microscopy, electron microprobe analysis and x-ray diffraction. Essentially single phase samples CeCo(9 + δ)Si(4 - δ) (structure-type LaFe(9)Si(4) with space group I4/mcm) are formed in a narrow composition range - 0…
A class of conjugated molecules containing donor (thiophene) and acceptor (malononitrile) is synthesized by Knoevenagel condensation reaction between 2-(2,6-dimethyl-4H-pyran-4-ylidene) malononitrile and thiophene carbaldehyde containing two and three thiophene units. The resulting molecules are characterized by (1)H…
The high temperatures required to operate solid oxide fuel cells (SOFCs) allow for internal reforming of hydrocarbon fuels over a Ni-based anode. With their capability of being fuel flexible, SOFCs have operated under a wide range of fuels including diesel as examined in this study. But in order to reduce high possibi…
Abstract Reaction of iron(II) thiocyanate with 4,4‐bipyridine (bipy) in methanol leads to the formation of three new solvates of different composition depending on the reaction conditions: At room temperature two new ligand‐rich 1:2 (1:2 = ratio between metal and N‐donor ligand) polymorphic forms [Fe(NCS)2(bipy)2·2MeO…
