The alloy with the composition of Mg2Ni prepared by low-temperature solid-phase sintering was mechanically milled for 10, 25, 40 and 50 h. The microstructures and electrochemical properties of the Mg2Ni alloys were investigated by X-ray diffraction (XRD), optical microscope (OM) and electrochemical measurements. Furth…
This paper focuses on an evaluation of core losses in laminated magnetic block cores assembled with a high Bs nanocrystalline alloy in high magnetic flux density region. To discuss the soft magnetic properties of the high Bs block cores, the comparison with amorphous (SA1) block cores is also performed. In the high Bs…
We investigate the ground-state properties of triangular graphene nanoflakes with zigzag edge configurations. The description of zero-dimensional nanostructures requires accurate many-body techniques since the widely used density-functional theory with local density approximation or Hartree-Fock methods cannot handle…
Surveys on wave propagation in dispersive media have been limited since the pioneering work of Sommerfeld [Ann. Phys. 349, 177 (1914)] by the presence of branches in the integral expression of the wave function. In this article a method is proposed to eliminate these critical branches and hence to establish a modal ex…
ABSTRACT An analogue of disubstituted 3,4‐propylenedioxythiophenes, namely 3,3‐bis(cyclohexylmethyl)‐3,4‐dihydro‐2H‐thieno[3,4‐b][1,4]dioxepin (ProDOT‐CycHex2), was synthesized and its electrochemical polymerization was carried out successfully in an electrolyte solution of 0.1 M tetrabutylammonium hexafluorophosphate…
Friction stir welded (FSW) magnesium alloys usually exhibit a lower yield strength and elongation compared with base materials. In this study, large load FSW associated with an extremely low welding speed and rotation rate were applied to a non-combustive Mg–6Al–0.4Mn–2Ca magnesium alloy to modify the microstructure a…
Generally, the plasmonic Fano resonances can be divided into two types: the electric and the magnetic Fano resonance. Compared to pure electric or magnetic multiple Fano resonances, the mixed electric/magnetic multiple Fano resonances provide more flexibility for their application in multiwavelength surface enhanced R…
When one-dimensional (1-D) nanomaterials (e.g., nanotubes, nanowires, nanofibers, nanoribbons) are suspended in a liquid droplet, once the liquid evaporation occurs at elevated temperatures, the system equilibrium will break, leading to large deformation, instability, and self-assembly of the 1-D nanomaterials. In the…
High Resolution Image Download MS PowerPoint Slide A magnetically active Fe 3 O 4 /poly(ethylene oxide)- block -poly(butadiene) (PEO- b -PBD) nanocomposite is formed by the encapsulation of magnetite nanoparticles with a short-chain amphiphilic block copolymer. This material is then incorporated into the self-assembly…
(-)-Balanol is an adenosine triphosphate mimic that inhibits protein kinase C (PKC) isozymes and cAMP-dependent protein kinase (PKA) with limited selectivity. While PKA is known as a tumor promoter, PKC isozymes can be tumor promoters or suppressors. In particular, PKCε is frequently involved in tumorigenesis and a po…
Abstract This report demonstrated the effect of Zn/Cr element ratio on Zn−Cr catalyst for isobutanol formation from the reaction of carbon monoxide hydrogenation. The catalysts of different Zn/Cr element ratios including 1 : 3, 1 : 1, 3 : 1 and 5 : 1 have been prepared by a facile coprecipitation approach and their ac…
In the present work, a detailed analysis of the glassy behavior and the relaxation dynamics of the liquid crystal dimer \ensuremath{\alpha}-(4-cyanobiphenyl-4\ensuremath{'}-yloxy)-\ensuremath{\omega}-(1-pyrenimine-benzylidene-4\ensuremath{'}-oxy) heptane (CBO7O.Py) throughout both nematic and smectic-A mesophases by m…
The physical and chemical principles of the preparation of carbon nanoparticles (fullerenes, carbon nanotubes) and their complexes, and the methods for introducing nanoparticles into metal, ceramic and polymer matrices are considered. The most important properties of some materials containing these cluster molecules a…
Abstract Despite the scientific and technological importance of removing interface dangling bonds, even an ideal model of a dangling-bond-free interface between GaN and an insulator has not been known. The formation of an atomically thin ordered buffer layer between crystalline GaN and amorphous SiO2 would be a key to…
Abstract Theoretical and computational analysis of the magnetotransport properties and spin-transfer torque field-induced switching of magnetization density in vertically-stacked multilayers is presented. Using epitaxially-capped free layers of Pt and Fe, atom-resolved magnetic moments and spin-transfer torques are co…
Western Superconducting Technologies Co. Ltd. (WST) has been keeping in the research and development of internal-tin Nb3Sn strand for higher performance level, for the future fusion reactor after ITER. Deformation optimization, Cu splits, and Sn spacers were applied to prepare Nb3Sn strand with higher Jcnand lower hys…
Abstract The global attention has been focused on degradation of the environmental organic pollutants through green methods such as advanced oxidation processes (AOPs) under sunlight. However, AOPs have not yet been efficient in function of the photocatalyst that has been used. In this work, firstly, CaCu3Ti4O12 nanoc…
We demonstrate a method of conformally coating conjugated polymers on arbitrary substrates using a custom-designed, low-pressure reaction chamber. Conductive polymers, poly(3,4-ethylenedioxythiophene) (PEDOT) and poly(3,4-propylenedioxythiophene) (PProDOT), and a semiconducting polymer, poly(thieno[3,2-b]thiophene) (P…
Engineering components operating at high temperature often fail due to the initiation and growth of cracks in the heat-affected zone adjacent to a weld. Understanding the effects of microstructural evolution in the heat-affected zone is important in order to predict and control the final properties of welded joints. T…
Protein structure prediction servers use various computational methods to predict the three-dimensional structure of proteins from their amino acid sequence. Predicted models are used to infer protein function and guide experimental efforts. This can contribute to solving the problem of predicting tertiary protein str…
