The soft magnetic composite (SMC) is a new type of soft magnetic material made of insulated iron powders. Its special characteristics could enable the development of low cost high performance electrical machines. This paper presents the measurement and modelling of magnetic properties of SMC under 3D magnetizations. D…
Unconditional stability criteria for a linear two-port have been derived in the literature from the two-port immittance matrix (the Rollett approach), or from theS-parameters (as proposed by Kurokawa). In this paper, we stress some relations between the two strategies. First, we express the two- or single-condition st…
BACKGROUND: Silk fibroin blend films with α-helix cannot be used as biomaterials due to water-soluble and unstable; however, β-sheet structure is stable. OBJECTIVE: To prepare for a β-sheet conformation silk fibroin composite films mixing fucoidan and to observe the physical and chemical characteristics of silk fibroi…
The oxime derivative of [1.1.1]cyclophane cyclotriveratrylene (CTV) was ring expanded utilizing a Beckmann rearrangement to provide a ten-membered N-acetyl macrocyclic amide that crystallizes as a chloroform monosolvate in columnar assemblies manifesting an unusual disorder within the crystal. Columns made up of this…
Diatoms are a micro-alga dominates in the aquatic ecosystem. Their silicious cell wall able to preserve death diatoms in the sediment for long periods of time, therefore, diatoms have an important role in the paleolimnological analysis. Diatoms assemblages in the sediment layer express the water quality whenever the d…
The periplasmic thiol-disulfide oxidoreductase SoxS is beneficial for the sulfur-oxidizing (Sox) phenotype of the facultative chemotrophic bacterium Paracoccus pantotrophus and is not part of the Sox enzyme system. SoxS combines features of thioredoxins, glutaredoxins and the thiol-disulfide oxidoreductases of the Dsb…
Double magnetic tunnel junctions (DMTJs) using half-metallic Co2MnSi Heusler alloy electrodes were fabricated. Their tunnel magnetoresistance (TMR) effects were then investigated. Large TMR ratios were observed as 25% at room temperature and as 320% at 6 K. The bias voltage dependence of tunnel conductance suggests a…
Room temperature synthesis of ordered-vacancy-compounds (OVCs) and copper indium diselenide (CuInSe2, CIS) by cation and anion exchange reactions of solid CdS thin films with CIS ionic solution in an alkaline chemical bath is reported. The growth parameters such as pH, deposition time and concentration of the solution…
Active metal−zinc pieces were used as an anode, and ammonium chloride was used as an electrolyte in an anode zone, with acids and soluble oxidant−bichromate as an active cathode substance and electrolyte in a cathode zone in a zinc−bichromate battery. Carbon felt was used as an inert cathode, with a PE-01 homogeneous…
A number of new ferrocene-pi-extended-dithiafulvalenes were successfully synthesized as new electron donor compounds. The chemical structures and electrochemical behaviors of these compounds were investigated using several spectroscopic methods. The synthesis of these compounds was achieved using the modified Wittig-H…
In order to explore the chemistry of the bidentate ligand 2,2-dimethylpropane-1,3-diyl diisocyanide and to investigate the effect of counter-ions on the polymeric structure of (2,2-dimethylpropane-1,3-diyl diisocyanide)silver(I) complexes, the title polymeric compound, [AgI(C(7)H(10)N(2))](n), was synthesized by treat…
The extrusion process to produce a cross-shaped profile of a wrought magnesium alloy AZ31 was simulated to predict the exit temperature as a function of the initial billet temperature. Three-dimensional FE simulation revealed the evolutions of temperature and extrusion pressure during the process. The initial billet t…
The objective of this study was to evaluate the importance of oligomer effects for the assembly of functional rod/stack architectures on solid substrates. The original approach to the ‘zipper assembly’ of functional rod/stack architectures focused on p-quaterphenyl initiators and p-octiphenyl propagators with naphthal…
Experimental data obtained in a pilot-scale Kühni liquid−liquid extraction column were used to obtain local drop size distributions, dispersed-phase hold-up profiles, and solute concentrations. To obtain information about the dynamic behavior of the column, several experiments were planned and performed, under both st…
The DEDM (difference electron-density modification) algorithm has been described in a recent paper [Caliandro et al. (2008), Acta Cryst. A64, 519-528]: it breaks down the collinearity between model structure phases and difference structure phase estimates. The new difference electron-density produced by DEDM, summed t…
Abstract Die Aktivierung von elementarem Tellur mit Vanadium lieferte den Vanadium‐Bis(tellurid)‐Komplex [(PNP)V(Te)2] (siehe Struktur). Seine terminalen Tellurideinheiten können als Abgangs‐ oder Schutzgruppen fungieren, und sie maskieren {(PNP)VI}‐ oder {(PNP)VIII}‐Fragmente, wenn sie Oxidationsmitteln wie Aziden un…
Abstract Positron lifetime spectroscopy serves to determine the void volumes of cucurbituril (CB) capsules, which are not amenable to standard gas adsorption methods. In the case of the host–guest complex Au§CB[7], it also provides evidence of the inclusion of gold nanoparticles in the CB cavity (see space‐filling mod…
The stability of spin-spiral structures in an Fe monolayer on a W(110) substrate is investigated by means of the first-principles film full-potential linearized augmented plane-wave method, and the role of spin-orbit coupling (SOC) on the spin-spiral structures is determined. Our calculations demonstrate that without…
The intercalation of an acidic blue dye, Brilliant Blue FCF, into poly(allylamine) (PAA)/synthetic fluoromica (Na-TSM) was investigated as a function of the reaction pH (1.5−12.0) and the loading of the polyelectrolyte and acidic dye. Surprisingly, the colored solids so obtained show a variety of colors from the origi…
The diagonal and off-diagonal components of the effective permeability tensor and the effective permittivity of three-dimensional (3D) periodic magnetic nanosystems, depending on the size and separation of the magnetic nanoparticles, were calculated using the computed values of the propagation constants and the disper…
