Fracture behaviors of fibrillar silicate clay (MMT) filled thermoplastic polyolefin (TPO) containing polypropylene (PP) blended with ethylene-propylene-diene monomer (EPDM) were systematically investigated using impact test method and J -integral by locus method. Drastic increase in impact strength is observed for all…
A recent publication [Opt. Express16, 20540-20561 (2008)] presented a way for extending the depth of field (DOF) of imaging systems using a binary phase mask made of annular rings delivering a π-phase shift. Usually, such masks are designed with respect to some central wavelength; they will thus deliver a different ph…
ABSTRACT Self‐condensation of AB2 type monomers (containing one A‐type and two B‐type functional groups) generates hyperbranched (HB) polymers that carry numerous B‐type end‐groups at their molecular periphery; thus, development of synthetic methods that directly provide quantitatively transformable peripheral B group…
The time evolution of the ferromagnetic resonance output signal in the arrays of permalloy circular dots of submicron sizes was measured near the critical fields of the vortex nucleation and annihilation. Surprisingly short times of the transition from the quasiuniform to the vortex magnetization state (several millis…
Double walled carbon nanotubes (DWNTs) have unique coaxial structures and corresponding physical and chemical properties, making them good candidates for supercapacitor materials. However, there are almost no reports on DWNT based composites for supercapacitor applications. In this study, a DWNTs/PAni composite was sy…
For practical guest–host applications, it is important to choose dyes with a high ability of orientation in the liquid crystal (LC) matrix. In this experimental work, two different azo-structured dyes (disperse yellow 3 and 7) were separately doped to each of two different nematic LCs (E7 and ZLI-1132). Their solubili…
Abstract The off-axis tensile strength (OATS) of copy paper, filter paper, and sack paper was obtained from dog-bone specimens. The relationship between OATS and the off-axis angle (OAA) was predicted under several failure conditions. Additionally, the shear strengths (SS) of these papers were evaluated based on the r…
ABSTRACT Multiwalled carbon nanotube (MWCNT) crosslinked polyurethane nanocomposites filled with iron (Fe) powders were synthesized by an in situ polymerization method. The Fe powders were deposited on one side of the nanocomposites during sample formation. Because of the gradient distribution of the Fe powders, the p…
We synthesize a polytriphenylamine homopolymer and two donor–acceptor copolymers (D–A-copolymers) based on triphenylamine (TPA) as donor in combination with two different acceptor moieties to study the effect of the acceptor unit on the excited-state charge-transfer characteristics (CT-characteristics) and charge sepa…
The dinitroxide bis(TEMPO) bisketal ( bTbk ) was shown to crystallize into open frameworks whose structures were determined by single-crystal X-ray diffraction. We show that bTbk can be used as a supramolecular building block for the hosting of a plethora of guests inside the 1D channels of its paramagnetic framework,…
Based on a one-pot/self-template synthesis strategy, mesostructured 1D vanadium oxide-embedded carbon nanofiber was prepared by combining electrospinning and carbonization methods. Cost-saving ammonium metavanadate was used as a semiconductor precursor and porogen. The novel membrane exhibited highly efficient and sta…
Excellent Langmuir-Blodgett films (LB) of non-amphiphilic coronene (COR) have been prepared by mixing with a long chain fatty acid, viz., arachidic acid (AA) and an inert polymer such as poly methyl methacrylate (PMMA) separately. Miscibility of the guest and host molecules in the mixed monolayer of COR and AA/PMMA ha…
As corrosion seriously reduces the service life of casing, considering no given formulas for remaining life calculation and the limitations of the laboratory tests and field data in investigating the lifetime of corrosion casing. To research the service ability of casing under uniform corrosion in steam injection well…
Electrical switching of single-gate all metal field emitter arrays is studied to generate subnanosecond electron pulses. By applying a bipolar current pulse method to the metal nanotip array, electron pulses with the duration down to 210 ps were generated. To explore the short-pulse limit of the proposed switching met…
A new intact resin glycoside (3) and two glycosidic acids (1 and 2), all having a common trisaccharide moiety and (11S)-hydroxytetradecanoic acid or (3S,11S)-dihydroxytetradecanoic acid as the aglycone, were obtained from the roots of Porana duclouxii. Their structures were elucidated by spectroscopic analyses and che…
The present paper deals with the studies concerning anodic regeneration of exfoliated graphite (EG) electrodes coated with oligomer products of incomplete phenol electrooxidation. The electrochemical activity of regenerated samples depends on the concentration of regenerating electrolyte and potential applied during t…
Efficient descriptions for Fano resonant properties of plasmonic arrays of nanoparticles could support selection of particle and array characteristics to achieve specific spectral outcomes. In contrast to conventional particle-by-particle computation of Fano resonances from arrayed particles, this work uses polylogari…
A series of amphiphilic star-shaped copolymer, poly(dimethylaminomethyl methacrylate)-block-poly(2-hydroxyethyl methacrylate -graft- poly(ϵ-caplactone)), s(PDMAEMA-b-P(HEMA-g-PCL))4, were synthesized by atom transfer radical polymerization (ATRP) and ring opening polymerization (ROP) with PDMAEMA as hydrophilic star c…
The superconducting proximity effect on two-dimensional massless Dirac electrons is usually analyzed using a simple model consisting of the Dirac Hamiltonian and an energy-independent pair potential. Although this conventional model is plausible, it is questionable whether it can fully describe the proximity effect fr…
We used density functional theory to calculate the phase stability of the hcp (hexagonal close packed) and the fcc (face centered cubic) structures of ScH3. The hcp form is stable up to 22 GPa according to the generalized gradient approximation calculation. Then the fcc form becomes energetically more stable. In order…
