The thermo-emf and electrical resistivity of hydrogenated titanium were measured. Hydrogen concentration in titanium varies from 0.005 to 0.25%. We have compared the methods regarding their sensitivity to the alteration of thermo-emf and electrical resistivity during titanium hydrogenation. The accuracy of the obtaine…
Gas-diffusion electrodes containing polytetrafluoroethylene, acetylene black A437E and its mixtures with two types of furnace black (P702 and P268E) with different size of particles are studied. The electrode capacitance, the average diameter and volume of pores and their surface area are investigated as a function of…
Ultrasonic propagation through nanofluids has now become a subject of great interest. It is a typical technique to examine the structure formation in nanofluid. Speed of sound can be considered to evaluate acoustical parameters and hence, to investigate physico-chemical properties of nanofluid. Investigation of these…
Abstract A transmission electron microscopy (TEM) investigation was undertaken in order to elucidate the nature of the structural disorder in a tobelite specimen from the sedimentary rocks of the Armorican sandstones (western France). This structural disorder may be the origin of residual electron-density maxima in di…
Amorphous InGaZnO (IGZO) is a promising semiconducting material to replace amorphous and polycrystalline Si. IGZO-based field-effect transistors (FET) can be versatile platforms for various electronic or optoelectronic applications. Here, we report on a one-dimensional (1-D) IGZO FET fabricated on a flexible polyimide…
It is well known that the presence of a highly conductive water film over ice-covered insulator is a prerequisite to form local violet arcs across air gaps. This paper develops a model for calculation the thickness and surface conductivity of the water film formed over ice-covered insulators due to Joule heating effec…
A linear stability analysis is performed to investigate the onset of convective motions in a flat cavity filled with liquid metal. A volumetric heat source is uniformly distributed in the fluid and a horizontal magnetic field is imposed. Walls perpendicular to the magnetic field are thermally insulating, and the top w…
Abstract The uranyl cage clusters (UO2)22(O2)15(PHO3)20(H2O)1026– (U22) and (UO2)28(O2)20(PHO3)24(H2O)1232– (U28) can be probed in aqueous solutions by using a combination of 1H Diffusion‐Ordered Spectroscopy (DOSY) and 1H‐31P Heteronuclear‐Single Quantum Coherence (HSQC) spectroscopy. This class of clusters is ideal…
We report the synthesis of free-standing two-dimensional semiconductor zinc oxide (ZnO) nanomembranes (NMs) using a bottom-up approach, i.e., nanomembranes grown from the faceted sidewalls of horizontally oriented ZnO nanowires (NWs). The ZnO NMs were synthesized on r-plane sapphire substrates utilizing high purity Zn…
In the heavy-fermion superconductor ${\mathrm{Ce}}_{1\ensuremath{-}x}{\mathrm{Yb}}_{x}{\mathrm{CoIn}}_{5}$, Yb doping was reported to cause a possible change from nodal $d$-wave superconductivity to a fully gapped $d$-wave molecular superfluid of composite pairs near $x\ensuremath{\approx}0.07$ (nominal value ${x}_{\m…
Solute segregation and formation of non-metallic inclusions during the solidification of a titanium-containing steel are modeled in this paper. The Ueshima model was used to describe the partitioning of solute elements in the steel, taking account of back-diffusion into the solid. Calculations were made for solidifica…
The influence of nonmetallic inclusions in Э76Ф rail steel on the high-temperature plasticity is considered. In terms of the shear strain, a plasticity maximum is observed in all three zones of the continuouscast billet: the crust, the columnar-crystal zone, and the central zone of the billet. The high-temperature tor…
OBJECTIVES: Methods for conservation and preservation of vascular grafts are often controversially discussed. Furthermore, immunologic monitoring or immunotherapy for allogeneic graft is not considered necessary in many cases. The present study was initiated to examine the cellular vitality and functional efficiency o…
This paper presents a method for acquiring true stress–strain curves using engineering strain curves obtained from upset forging of cylindrical specimens. The main problem deals with determination the true strain in upset hot forging on hummers when the values of strain rates are differ in the range from 0 to 10-3s. A…
Phase transitions (PTs) and frustrations in two-dimensional structures described by a three-vertex antiferromagnetic Potts model on a triangular lattice are investigated by the Monte Carlo method with regard to nearest and next-nearest neighbors with interaction constants J 1 and J 2, respectively. PTs in these models…
The current wave of wearable computing has mostly been about putting electronic smarts into fashion accessories of various forms: fobs, wristbands, gloves, shoes, and glasses. Meanwhile, the actual clothes we wear have been remarkably untouched by the digital revolution. But Anouk Wipprecht is leading the charge among…
A linearly-polarized receiving mode nanoantenna is designed for solar energy harvesting. The infrared nanoantenna is used to collect the solar radiation and converting it to electric energy. The proposed nanoantenna is a thin dipole made of gold and printed on a silicon dioxide substrate. The two poles of the dipole h…
We present CCN-DART, a more efficient forwarding approach for content-centric networking (CCN) than named data networking (NDN) that substitutes Pending Interest Tables (PIT) with Data Answer Routing Tables (DART) and uses a novel approach to eliminate forwarding loops. The forwarding state required at each router usi…
The characteristic values of the elastic polarizability tensor components of point defects in crystalline and amorphous copper, which determine changes in the elasticity tensor components upon introduction of defects, have been found using the molecular dynamics method. A relation of the elastic polarizability tensor…
We suggest that a potentially dominant but previously neglected source of pusher-fuel and hot-spot “mix” may have been the main degradation mechanism for fusion energy yields of modern inertial confinement fusion (ICF) capsules designed and fielded to achieve high yields—not hydrodynamic instabilities. This potentiall…
