The mechanical properties of Nylon 6,6 blended with recycled scrap material, polyvinyl butyral (PVB), using maleated styrene-ethylene-butylene-styrene block copolymer (SEBS-g-MA) as a compatibilizer are discussed. Control samples of Nylon 6,6/PVB blends and Nylon 6,6/SEBS-g-MA blends were also compared. The results sh…
Epitaxial La0.8Ag0.1MnO3+δ films of different thicknesses (500–1000 nm) were grown on ZrO2(Y2O3) substrates. Their optical, magneto-optical and transport properties were studied in order to clarify the effect of the epitaxial variant structure and Ag ion distribution on the conductivity, magnetoresistance and infrared…
The negatively charged oxygen donates an electron pair to the hydrogen, and the hydrogen attached to the nitrogen accordingly weakly bonds with oxygen. The nitrogen in the polyaniline backbone finally possesses extra negative charge due to the donation of electron density by the oxygen.
High impact polystyrene (HIPS) series was synthesized by the mass-suspension process using polybutadiene (PB) rubbers with different cis-1,4, trans-1,4, and vinyl-1,2 isomers content. The HIPS were characterized by TEM, GPC, DMA, and DSC analyses. It was found that the dynamic mechanical properties of HIPS strongly de…
Abstract Pale yellow, needle‐shaped single crystals of Sm 2 [SeO 3 ] 3 were obtained by heating stoichiometric mixtures of Sm 2 O 3 and SeO 2 (molar ratio: 1:3) along with substantial amounts of CsCl as fluxing agent in evacuated sealed silica tubes at 830 °C for one week. According to X‐ray single‐crystal diffraction…
In a study of the TDDB performance of an ultra-low-k (ULK) dielectric (JSR 5537 k = 2.3) it was found that the presence of moisture significantly reduced the TDDB lifetime as well as increased leakage and capacitance. It was also observed that the field coefficient (/spl gamma/) in an "E" TDDB lifetime model was signi…
Some mechanisms of the reduction reaction of NO by CO on rhodium are analyzed and discussed, solving the kinetics equations and using Monte Carlo simulations, in terms of its ability to interpret the recent experiments of Zaera et al., who used a molecular beam method to study experimentally the kinetics of the reacti…
Abstract Alcoholysis of [Fe 2 (O t Bu) 6 ] as a Simple Route to New Iron(III)‐Alkoxo Compounds: Synthesis and Crystal Structures of [Fe 2 (O t Amyl) 6 ], [Fe 5 OCl(O i Pr) 12 ], [Fe 5 O(O i Pr) 13 ], [Fe 5 O(O i Bu) 13 ], [Fe 5 O(OCH 2 CF 3 ) 13 ], [Fe 5 O(O n Pr) 13 ], and [Fe 9 O 3 (O n Pr) 21 ] · n PrOH New alkoxo‐…
We study the propagation of electromagnetic waves in infinite lines with grafted finite lines in a frequency regime, where the grafted lines have negative phase velocity. The physical properties of such a structure with negative phase velocity materials have not been investigated before, to the best of our knowledge.…
To cap it all…︁ The pyrolysis of a [CpFe(arene)]PF6 complex yielded new carbon nanocapsules in near-quantitative yield (see TEM image); the capsules contain an Fe–P composite material. The results show that the structure of the obtained material is highly dependent on the complex used in the pyrolysis experiments, and…
Porous titanium dioxide (Titania) thin films were grown by anodic oxidation using high purity (99.7%) titanium foil in a dilute sulphuric acid (1 M) medium. The anodization process was carried out for 30 minutes with 20 mA/cm2 and 50 mA/cm2 current densities. The samples were characterized by XRD, SEM, and AFM techniq…
Thermoluminescence (TL) glow-curves measured using an exponential heating function (EHF) in constant temperature hot gas readers, cannot be analysed using the existing single TL glow-peak equations derived assuming a linear heating rate. In the present work single TL glow-peak equations, which were recently derived as…
The application of in situ FBRM and PVM in monitoring the erythromycin dilution crystallization process and the transformation of erythromycin solvates is introduced. Influences of seeding strategies on nucleation and growth were examined in acetone aqueous solutions. It is noted by FBRM monitoring that the dominant c…
The SmC phase of 4'-octyloxyphenyl-4-octyloxybenzoate has been examined in light of recent reports that this phase is chiral. The results suggest that two varieties of chiral domains in LC cells of the phenylbenzoate are indeed formed, driven by interactions with surfaces. Application of sensitive probes for chirality…
Atmospheric pressure discharges are routinely used to functionalize rough surfaces of commodity polymeric materials to enhance surface properties. High value polymeric materials, such as scaffolding for tissue engineering, must also have their surfaces treated to achieve similar functionality. The techniques used to a…
A new tolane-base liquid crystal, 4'-heptyl-3-fluoro-4-isothiocyanatotolane (7TOLF), and a biphenyl-base nematogen, 4'-heptyl-3-fluoro-4-isothiocyanatobiphenyl (7BF), have been investigated for the first time to determine their electro-optical behaviour and third order non-linearity using the static Kerr effect method…
A nonmagnetic compound, [NO(2)BzPy][Au(mnt)(2)] (NO(2)BzPy(+) = 1-(4'-nitrobenzyl)pyridinium; mnt(2-) = maleonitriledithiolate), was synthesized and characterized structurally, which is isostructural with [NO(2)BzPy][Ni(mnt)(2)] that is a quasi-one-dimensional magnet and possesses a spin-Peierls-like transition with J…
Thermoplastic vulcanizates (TPVs) or dynamic vulcanizates containing finely dispersed micron-size cross-linked rubber particles in a thermoplastic matrix exhibit performance properties of the conventional vulcanized rubbers, however, they can be processed as thermoplastics. The basic objective of the present study is…
A low-temperature method for growing (0001)-oriented one-dimensional ZnO nanopillars using electrodeposition in a simple zinc nitrate aqueous solution without any template is presented. The 20–100 nm diameter ZnO nanopillars emitted ultraviolet light at around 3.30 eV due to the recombination of the bound excitons and…
Dosimeters of MgB4O7 doped with Dy and Na have many valuable features such as high sensitivity, tissue equivalence, low fading, non-requirement of annealing and insensitivity to light. Thermoluminescence studies of Dy and Na doped MgB4O7 samples showed that a glow emission peaked at about 195 degrees C. In this study,…
