Abstract The blends of carboxylated acrylonitrile butadiene rubber (XNBR) and natural rubber (NR) were prepared using a blending technique in the presence of different types of carbon black. The effect of filler on morphological and wear characteristics was studied. ISAF N234 carbon black showed a significant effect o…
The inhibiting action of N-cyclohexyl-N′-phenyl thiourea (CPTU) on the corrosion behavior of 304 SS in 3 M hydrochloric acid solution has been investigated using potentiodynamic polarization technique at four different temperatures. The results obtained reveal that CPTU acts as an efficient anodic inhibitor for the co…
Abstract Changes in morphology and chain dynamics of a series of drawn gel‐spun UHMWPE fibers were investigated by 1D and 2D 1 H, 13 C and 129 Xe NMR spectroscopy. The dependence of the rms oscillation angle for the internuclear proton spin pairs around the chain axis can be evaluated from 13 C/ 1 H WISE and correlate…
Transport measurements indicate strong oscillations in the Hall, ${R}_{xy}$, and the diagonal, ${R}_{xx}$, resistances and exhibit Hall plateaus at the lowest temperatures, in three-dimensional (3D) highly oriented pyrolytic graphite. At the same time, a comparative Shubnikov-de Haas-oscillations-based Berry phase ana…
The purpose of this paper is to show the degree of changes in mechanical and deformation properties of single cotton yarn after sizing depending on their fineness, size concentration and the structure created by the type of yarn spinning. The properties of ring and rotor-spun yarns were analyzed before and after sizin…
With the development of nanotechnology, there is a growing demand for advanced electronics based on functional nanomaterials. In this respect, owing to their unique properties, conducting polymers (CP) synthesized in the form of one-dimensional (1D) nanostructures are of particular interest. In this feature paper, we…
In this paper, the two-way shape memory effect (TWSME) in a Ti–54.5 Ni(wt%) alloy was investigated experimentally to develop a NiTi linear actuator. The two-way shape memory effect was induced through a compressive shape memory cycle comprising four steps: (1) loading to maximum deformation; (2) unloading; (3) heating…
Resonant charge transfer during low energy ion scattering reveals correlated-electron behavior at high temperature. The valence electron of a singly charged alkaline-earth ion is a magnetic impurity that interacts with the continuum of many-body excitations in the metal, leading to Kondo and mixed valence resonances n…
We present the experimental and theoretical study of x-ray photoelectron spectroscopy spectrum of ${\text{LaNiO}}_{3\ensuremath{-}x}$ thin films deposited onto a (100)-plane oriented ${\text{NdGaO}}_{3}$ substrate by applying a reactive dc magnetron sputtering technique. The crystal calculations carried out within pur…
In the wake of previous studies on the rattling-and-jumping diffusion in smectic liquid crystal phases of colloidal rods, we analyze here for the first time the heterogeneous dynamics in columnar phases. More specifically, we perform computer simulations to investigate the relaxation dynamics of a binary mixture of pe…
Self-assembled multilayer films of hyaluronic acid (HA) and the protein myoglobin (Mb) were built up layer by layer on Au covered quartz crystal microbalance (AuQCM) electrode substrates. Film formation and growth were monitored by an electrochemical quartz crystal microbalance (EQCM), and the step-by-step constructio…
Superconductivity at 33 K in ${\text{Sr}}_{2}{\text{VO}}_{3}\text{FeAs}$ is completely suppressed by small amounts of V doping in ${\text{Sr}}_{2}{\text{VO}}_{3}({\text{Fe}}_{0.93(\ifmmode\pm\else\textpm\fi{}0.01)}{\text{V}}_{0.07(\ifmmode\pm\else\textpm\fi{}0.01)})\text{As}$. The crystal structures and exact stoichio…
Single sepiolite clay needles doped with dyes of different molecular dimensions, Rhodamine 6G (R6G), Pyronine Y (PY), Styryl 698 (LDS 698) and Styryl 722 (LDS 722), at low and high loadings, are studied by confocal fluorescence microscopy. The combination of fluorescence lifetime imaging (FLIM), polarized fluorescence…
The authors evaluated the electron detection performance of a diamond avalanche diode (DAD) detector. In the electrode region, the gain was uniformly about 103 with little noise. Meanwhile, an avalanche multiplication occurred locally. In the avalanche region, a total gain of 5×104 was obtained. In some regions where…
Abstract The photografting of methacrylic acid (MAA) onto high‐density polyethylene (HDPE) initiated by aliphatic ketones (acetone, butanone, and cyclohexanone) in aqueous solutions with different pH values adjusted by adding different amount of mineral acids was reported. Acids significantly enhanced the photograftin…
A well-defined styrenic block copolymer was prepared through controlled/“living” radical polymerization technique and evaluated as a polymeric surface modifier for multiwalled carbon nanotube (MWCNT) in α-terpineol-based paste. First, poly(maleic anhydride- co - p -acetoxystyrene)- block -poly( p -acetoxystyrene) copo…
A series of semicrystalline block copolymers (BCPs), poly(4-vinylpyridine)-block-poly(ε-caprolactone) (P4VP-PCL), with lamellar phases have been synthesized. P4VP-PCL BCP thin films with large-scale, oriented lamellar microdomains were obtained by rimming coating process followed by oscillated shearing using a homemad…
Gemischte Röhrchen: Ein neuartiger trägerfreier PdAuCu-Nanopartikel-Katalysator wurde synthetisiert (siehe TEM-Bild und Ergebnisse der energiedispersiven Röntgenspektroskopie). Der Einbau von Au in das PdCu-System wirkte sich positiv auf die Resultate der Sauerstoffreduktion (ORR) und der H2O2-Reduktion aus. Der Ansat…
This paper reports an investigation on the vibration of an individual multilayered graphene sheet with initial stress, based on an elastic plate model and membrane model with simply supported ends, considering the van der Waals force interaction between all layers of graphene sheets. The effect of initial stress is mo…
We study the correlation between photoinduced electron transfer and performance of photovoltaic devices. We have considered hybrid core−shell nanoparticles, where such an electron transfer occurs from an inorganic core to an organic shell layer. From photoluminescence (PL) quenching and decrease in PL lifetime, we fin…
