In this research, a modeling and experimental study was conducted to explore the effects of nanoparticle type (aluminum nanoparticles and carbon nanotubes), filler concentration and interactions between the nanoparticle and reinforcing fibers on through-thickness conductivity of nanoparticle/epoxy nanocomposites and n…
The multiphase field (MPF) method is recognized as a powerful numerical method to simulate microstructural evolutions, such as solidification, grain growth, recrystallization, and phase transformation, in various materials. However, because we need to solve the time evolution equations for multiple-order parameters de…
Water droplet mobility can be reversibly controlled based on surface grafted stimuli-responsive polymer brushes by in situ liquid–solid interface chemical reactions. By regulating the pH of a droplet in situ, the real-time dynamic tuning of the chain conformation between the swollen state (hydrophilic) and collapsed s…
In this numerical study, the influence of the choice of metal (and hence of the conductivity) used for the fabrication of THz fishnet metamaterials is investigated. We explore an exemplary structure for which surface-plasmon-polaritons offer – assuming sufficiently good conductivity – pronounced extraordinary transmis…
The solid oxide fuel cell single cells with porous cathodes prepared at various sintering temperatures, having remarkable differences in micro/meso porosity, were studied using impedance, cyclic voltammetry and chronoamperometry measurement methods. Atomic force microscopy, scanning electron microscopy, focused ion be…
Este trabalho teve por objetivo avaliar a qualidade de compensados fabricados com adesivos base de taninos da casca de Pinus oocarpa e Fenol-Formaldedo (FF). O plano experimental foi composto de quatro tratamentos: Tanino-Formaldedo (TF); Fenol-Formaldedo (FF); FF + 10%TF (90:10), e FF + 20% TF (80:20). Os painis fora…

Dense lead zirconate titanate (PZT) ceramics is typically used for fabrications of high power piezoelectric devices. In case of lanthanum and iron ions doping into PZT solid solution (PLFZT), material exhibiting both piezoelectric and magnetic properties can be obtained. Among many investigated compositions particular…
A series of Ru(II) complexes with monosilylated-dipyridine ligand have been synthesized and fully characterized and were then covalently attached to silica nanoparticles. Two types of hybrids were obtained depending on the experimental procedure. In the first approach, metal complexes were incorporated inside the sili…
The NMR heteronuclear relaxation rate's dependency on the anisotropy of rotational diffusion motions can be exploited to investigate the supramolecular organization that results from reversible peptide self-assembly in solution. The measurement of longitudinal (R1) and transverse (R2) 13C relaxation rates for several…
Lotus-type porous copper was fabricated using unidirectional solidification method by only changing casting temperature. Porous structure of the lotus-type porous copper was quantitatively characterized and analyzed. Effect of casting temperature on the porous structure was investigated and its mechanism was discussed…
Dispersed superparamagnetic Fe3O4–Ag hybrid nanocrystals were successfully synthesized by a seed-assisted hydrothermal strategy. The diameter of the Fe3O4–Ag nanocrystals is 10–20 nm, and the magnetization saturation is over 40 emu g−1. This facilitates their potential applications in magnetic resonance imaging for me…
We started with a conventional steadystate direct method to measure thermal contact resistances (TCR) of Cu/Cu, SS304/SS304 and Al2O3 /Al2O3, but later found that it is not applied to measure the TCR of thin test pieces. In the study of thermal resistance of the interface materials with graphite sheets and gel sheets…
Ascorbic acid molecules in either acid or conjugate base forms have been oxidized on self-doping carboxylated polyaniline thin films. The kinetic model proposed by Bartlett et al. has been successfully applied to the catalytic reactions. Active sites in the polymer have been identified as the rings having quinoid char…
Nonlinear optical single crystals of Ethylene Diamine Tetra Acetate (EDTA) doped lithium sulphate monohydrate are successfully grown by using slow evaporation technique at room temperature with double distilled water as solvent. In order to know its suitability for device fabrication, different characterization analys…
In previous study, the role of graphite on tribological behavior of cast iron was examined, and the model of cast iron in wear mechanism was proposed. However, this wear mechanism is the model for macro scale test, and has the possibility of showing behavior different from the model shown by the macro scale test in mi…
Photonic crystal coupled with plasmonic nanoparticle arrays to form a periodic plasmonic architecture was prepared by loading Au nanoparticles inside the inverse opal TiO(2) film. The visible and near infrared light absorption was increased by 62% and the overall light-to-electricity conversion yield was thus increase…
Thermal properties of molten and mixed core materials are required to be known for effective analysis of core damage in severe accidents at nuclear power plants. The specific heat capacity, thermal expansion coefficient, thermal diffusivity, and melting temperature were measured or estimated on the core debris samples…
There is tremendous increase in research activity and publications in Polymer matrix composite materials and nanostructures in the last few years, this article is an attempt to identify the topics that are most relevant to Shape Memory Polymer Composite (SMPC) materials and review representative journal publications t…
The coupling between the spatial modulation of the order parameter and the electric polarization, known as the flexoelectric effect in liquid crystals, appears in spin structures in the case of magnetic media. In this paper the various implications of spin flexoelectricity are reviewed including: magnetically induced…
