Graphene nanoplatelets (GNP) were prepared by ball milling, and characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). PMMA/GNP composites were produced by a melt process. The flammability of PMMA/GNP composite was evaluated by the cone calorimeter (Cone) and thermal degradation of the compos…
Modeling of field-induced magnetization in ferromagnetic materials has been an active topic in the last dozen years, yet a dynamic treatment of distance-dependent exchange integral has been lacking. In view of that, we employ spin-lattice dynamics (SLD) simulations to study the external field effect on magnetic order…
A nonlinear optical crystal of potassium-doped meta-Nitroaniline (mNAK) was grown by slow evaporation method using methanol as solvent. The growth mechanism was understood by chemical etching studies. The presence of potassium in the crystal was identified by energy-dispersive X-ray diffraction. Lattice parameters for…
Abstract The synthesis, characterization, and application as CVD precursors of several new dimethyl(norbornadienyl)platinum(II) compounds are reported. Initially, synthesis is performed in a two‐step procedure from K2PtCl4with (Rnbd)PtI2as an intermediate, but a convenient “one‐pot” procedure is developed that allows…
The generalized diagram of the critical Grashof numbers as functions of the Prandtl number is presented. The diagram shows the zones of occurrence of flow field and temperature fluctuations in the axisymmetric and three-dimensional formulations of the crystal growth model using the pulling from a melt. The structure o…
This paper presents design considerations for a shock tube experimental rig used to investigate the dynamic failure mechanisms of shell geometries subjected to water shock impact loading. In such setup, it is desirable that the drive pressure used within the tube can provide a wide range of impulsive loads on the test…
Abstract The carbon nanotubes (CNTs)-containing composites of poly(butylene succinate) (PBS) were prepared by melt-blending in a batch mixer with three concentrations by weight of CNTs: 1, 2 and 3 %. State of dispersion-distribution of the CNTs in the PBS matrix was examined by electron microscopic observations that r…
The properties of TiO 2 thin film grown under potentiostatic mode are investigated by the linear voltammetry, photo-electrochemical technique and capacitance measurements. The anodic film thickens up to ∼10 nm by diffusion-controlled process and the growth obeys to inverse and direct logarithmic laws respectively in a…
Theoretical and experimental studies of longitudinal and lateral vibrations in a 2D cavity filled with foam viscoelastic material were performed; measurement methods of Lame parameters, as well as viscosity parameters with longitudinal and lateral resonance vibrations in cellular polypropylene loaded by a final mass w…
Nanoparticles of BiFeO3 (BFO) are incorporated in the nanocomposite of (BiFeO3)0.50 (Co0.4Zn0.4Cu0.2 Fe2O4)0.5, (BFO-CZCF) and these are prepared by chemical route. The formation of pure crystallographic phase of each component (BFO and CZCF) in the nanocomposite of BFO-CZCF has been confirmed by Rietveld analysis of…
Cumulative isochronal annealing of stainless steel 1.4307 samples deformed by compression was investigated using the Doppler broadening of the annihilation line measurements. Higher level of plastic deformation is accompanied not only by higher concentration of defects but also by higher amount of martensite. The anne…
The activity of Pt/Pd/C ETEK catalysts of the core-shell type with an ultralow content of platinum (0.5–15 μg cm −2 ) based on a commercial palladium catalyst is shown to exceed the activity of commercial Pt/C ETEK catalysts in the oxygen reduction reaction. The activity sharply increases with the decrease in the plat…
A microwave-absorption material with a wonderful microwave response is realized by M. Cao, H. Jin, W. Wang, and co-workers, who grow NiO nanorings on the surface of silicon carbide via a facile two-step strategy described on page 214. The SiC assembled with NiO nanorings exhibits highly enhanced dielectric properties…
Formation of asphaltene deposition during oil production, processing and synthesis is known as a fundamental problem of petroleum reservoir worldwide. Asphaltene is a petroleum fraction that can lead to increasing the operating costs in these industries. Variations in operational pressure, temperature and fluid compos…

We investigated the thermoelectric properties of melted crystalline ingots and hot-press sintered compounds of Bi2−x Cu x Se3 (x ≤ 0.1). The divalent cation substitution of the Cu-ion at the Bi-site increases the carrier densities because of hole doping, resulting in a decrease in Seebeck coefficient due to electron-h…
The experimental study of Double Negative (DNG) state of electromagnetic wave propagating in lanthanum manganite-perovskites doped with strontium La1-xSrxMnO3 is provided firstly below individual Curie temperatures (in ferromagnetic metal state (FM) for La1-xSrxMnO3). Various dopant concentrations are considered for c…
On page 392, Valentina Benfenati, Maria Rosa Antognazza, Michele Muccini, and colleagues show how the photostimulation of a semiconducting polymer blend modulates the ion channel conductance of astrocytes cultured on top of the device. The device can be used as a selective tool to study ion channel conductances in non…
This paper presents a new method for thermal characterization of THz Schottky diodes. The method is based on the transient current behavior, and it enables the extraction of thermal resistances, thermal time-constants, and peak junction temperatures of THz Schottky diodes. Many typical challenges in thermal characteri…
Analysis and research into properties and parameters of different-type laminated magnetic cores of three-phase power transformers are conducted. Most of new laminated magnetic core designs are found to have significant shortcomings resulted from design and technological features of their manufacturing. These shortcomi…
