The mechanism of benzil-like voltage stabilizers with the tailored side-chain architecture for enhanced dielectric electrical breakdown strength of cross-linked polyethylene at the atomic and molecular levels has been investigated.
Abstract Beton verhält sich unter dynamischer Belastung anders als unter statischer Belastung. Als wesentliche stoffliche Ursache hierfür werden üblicherweise innere Transporteffekte bei niedrigen Dehnraten bis ca. ϵ = 1/s angenommen. Bei höheren Dehnraten bis ca. ϵ = 300/s werden vermutlich Trägheitseffekte bei der B…
A large remanent polarization close to theoretical value 80 μC/cm2 of bulk PbTiO3 is achieved in epitaxial heterostructures of (120–600)-nm-thick PbTiO3 films grown by pulsed laser deposition on (001) SrTiO3 substrate using a 100-nm-thick SrRuO3 bottom electrode layer. The heterostructures employing a 50-nm-thick elec…
The wire beam electrode (WBE) method was employed to study water-line corrosion of carbon steel under static condition. It was found that, it was the thin electrolyte film that aggravated the corrosion of steel in water-line area, not the difference of oxygen concentration. The difference of oxygen concentration decid…
In this paper pure ZnO and doped Bi–ZnO powders annealed at 200 °C were prepared using conventional solid state reaction and were applied as photocatalysts for Cr(VI) reduction. Structural properties were studied using X‐ray diffraction (XRD) and optical properties were investigated using photoluminescence (PL) spectr…
Macromolecular contrast agents are very attractive to afford efficient magnetic resonance imaging (MRI) visualization of implantable medical devices.
Calcium phospate crystals with a thin nacreous structure were synthesized and characterized.
Molecular assembly of bisthienylethene Th2im (1) and [ReCl6]2− anions leads to the complex (Th2imH)2[ReCl6] (2), in which a [ReCl6]2(-) anion connects two equivalent Th2imH+ cations through Cl⋯N/C hydrogen bonds. Crystal structures of 1 and 2 indicate that two thiophene groups of each Th2im/Th2imH+ molecule adopt a ph…
Iron oxide nanoparticles (IONPs) can cause significant health problems due to their unique physicochemical properties and environmental characteristics. They are found as ultrafine particles in ambient air. After inhalation, these particles move from the lung to phagocytosis tissues, especially the liver. The aim of p…
We present a minimalistic equilateral triangular lattice model showing explicitly that the two-dimensional hydrogen model for excitons breaks down for excitons in semiconducting monolayer transition-metal dichalcogenides due to lattice effects and that these excitons are neither Wannier nor Frenkel excitons but rather…

A novel luminescent Polyacrylonitrile(PAN) nanofibre encapsulating silica nanoparticles carried ternary europium complex with α-thenoyltrifluoroacetone(htta) and 1,10-phenanthroline (phen) [Eu(tta)3phen (EuTP)] was obtained via electrospinning technique. Silica nanospheres carried Eu3+ complex achieved by sol-gel tech…
Undoped and Ti doped ZnO thin films were made by sol-gel spin coating, and the investigation of structural, morphological and optical features was applied as a function of the doping ratio. The films had a polycrystalline ZnO wurtzite crystal structure with (002) preferential direction and film crystallinity decreased…
Polymer nanocomposites have advantage over traditional materials in electrical properties from the standpoint of dielectrics and electrical insulation. The influences of nanoparticle dispersion in the matrix, which is mainly caused by different preparation methods, on the dielectric properties of composites have been…
For potential applications of metasurfaces in lens technologies, we propose a cross circularly polarized focusing metasurface which is capable of transforming a circularly polarized wave into cross-polarized wave and simultaneously focusing electromagnetic wave. A helicity-dependent phase change is introduced into the…
Recently, metamaterials have attracted considerable attention because of their unique properties and potential applications in many areas, such as in bio-sensing, imaging, and communication. Among these researches, the metamaterial absorber has aroused much interest of researchers. The metamaterial absorber is importa…
We present the effect of different stacking orders on carrier transport properties of multi-layer black phosphorous. We consider three different stacking orders AAA, ABA and ACA, with increasing number of layers (from 2 to 6 layers). We employ a hierarchical approach in density functional theory (DFT), with structural…
The present work investigates the inhibition of Jatropha Stem Extract (JSE) in sea water using mild steel coupons of dimension 5 × 5 × 0.5 cm. The cupons were immersed in test solutions of sea water and varied concentrations of extracts of 0.1g/l to 0.9g/l were used. The functional groups of the compounds were analyze…
The demand for space-borne telescopes with an aperture of 20 m is forcing the development of large diameter diffractive Fresnel zone lenses (FZLs) on membranes. However, due to the fabrication errors of multi-level microstructures, the real diffraction efficiency is always significantly smaller than the theoretical va…
It is shown that a record power conversion efficiency (PCE) of 1.25% can be obtained through coating reduced graphene oxide/n-silicon (rGO/Si) solar cell with silver nanowires (Ag NWs) and subsequently GO. rGO/Si solar cells were obtained through one step spin coating of GO on patterned n-silicon wafer followed by the…
