Organic conducting materials display great potential to be efficient thermoelectric materials according to the latest reports. On page 6829, W. Xu, D. B. Zhu and co-workers review thermoelectric and related properties of organic conducting materials, including polymers and small molecules, and highlight the most recen…
This document proposes the comparison of four statistical classification models for partial discharge (PD) classification as follows: k-nearest neighbors (KNN) model, probabilistic neural network (PNN) model, and other two statistical models using principal component analysis (PCA) for a data reduction approach combin…
Tradition of using natural fibers in automotive exterior and interior components are essential to recover eco-efficiency and renewability. Natural fibers have recently become sociable to automotive industry as an alternative reinforcement for synthetic glass fiber reinforced thermoplastics. Bumper beams are essential…
In this work firstly Fe3O4 nanoparticles were synthesized via a sono-chemical method. At the second step magnesium hydroxide shell was synthesized on the magnetite-core under ultrasonic waves. For preparation Fe3O4-MgO the product was calcinated at 400 ºC for 2h. Properties of the product were examined by X-ray diffra…
This paper investigates the use of a cylindrical microwave cavity resonator to measure the complex permeability of mixtures of magnetite (Fe3O4) and silicon dioxide (SiO2) using different field orientations. The weight percentages of the mixtures are varied and the effective bulk permeability is measured at frequencie…
Fully atomistic molecular dynamic simulations were performed to address the self-assembly of amphiphilic and comb-like polybenzoxazines (iBnXz) in water, with i = 3 (trimer), i = 4 (tetramer); i = 6 (hexamer), i = 8 (octamer), and i = 10 (decamer). Spontaneous aggregation of these comb-like polybenzoxazine molecules i…
The low thermal conductivity of polymers can be improved with the incorporation of fillers with a relatively high thermal conductivity. However, the improvement which can be achieved depends not only on the filler properties but also on the interaction between the polymer matrix and fillers. In this study, a variety o…
The foundation for modern information technology (IT) is integrated circuits chips, and more than 90% of the chips are composed of devices fabricated using complementary metal-oxide-semiconductor (CMOS) nanotechnology. After miraculous developments of five decades, Si CMOS is moving into 14 nm node, and will arrive at…
In this work, we present both fabrication process and characterization of graphene field-effect transistors. Large scale monolayer graphene was grown by chemical vapor deposition (CVD) on Cu foils and transferred over pre-patterned back-gated devices on Si/SiO2substrate. Scanning electron microscopy, Raman spectroscop…
In this paper, the time-domain measurement method for audible noise is employed to study the time and frequency domains characteristics of audible noise generated by single corona discharge under DC and AC voltage in a coaxial geometry. The results show that in time-domain the audible noise from positive and negative…
Highly-oriented Cu 2 O thin films were prepared by low temperature thermal oxidation of evaporated Cu thin films. The films were doped with different doses of nitrogen by ion implantation. An absorption peak appears below the absorption edge in the absorption spectrum of highly nitrogen doped Cu 2 O. The effect of nit…
A eutectic lead–tin alloy was prepared by melting the commercially pure metals and cast in cylindrical molds with 10 mm diameter. The billets were processed by 4 passes of ECAP using a die with 90° between channels through route A and rolled to a final thickness of ∼1 mm. The microstructure was determined by optical m…
Topologically protected domains, composed of mutually coupled ferroelectric, (anti)ferromagnetic, and antiphase domains, are widespread in hexagonal manganites. We have applied the extended Howie‐Whelan equations in hexagonal systems and simulated the electron‐diffraction intensities of four kinds of representative he…
Taking cues from nature’s nacre material, several composite design features have been identified as promoting strength and ductility in an otherwise brittle system. These features are to be adapted to, and evaluated for feasibility on, a scale, and with processing routes, applicable to civil infrastructure in an effor…
In this paper, we studied how field emission from thermally evaporated W18O49 nanowires depended on temperature. As the temperature changed from 300 K to 723 K, we found anomalous changes in emission current. Below an applied field of ∼12.5 V μm−1, the emission current tended to increase with rising temperature, while…
In this work, a polymer blend of High Density Polyethylene HDPE and Styrene-Ethylene-Butylene-Styrene SEBS triblock copolymer has been prepared. The composition of the blend was tailored to control the morphology from a state of dispersed droplets of SEBS in a PE matrix to a fiber-like morphology. The microstructure o…
Zinc oxide (ZnO) thin films were grown on three kinds of substrates (copper, silicon and glass) by the SILAR method. The solution was prepared by using zinc sulphate ZnSO4and ammonia NH3. And for rinsing, we heated the distilled water at the temperature 80°C. The nature of substrate was found to have effect on the cry…
The article considers the one-dimensional problem of the destruction of the simplest model of adhesively engage consisting generally of the many plates, which are substrates (what are glued) and adhesives (glues). The ability of the model to resist to thermal impact without fracturing here conventionally called the th…
This paper presents materialization through a device of severe plastic deformation process by multiaxial forging. In essence, by design, the device includes a board reinforced with fretting rings where the severe plastic deformation takes place and an assembly, punch-counterpunch that transmits the force from the sour…
