Non-equilibrium molecular dynamics (NEMD) simulations are used to compute the phonon thermal conductivity (k) for liquids and glasses of composition Mg 2 SiO 4 , CaMgSi 2 O 6 , and NaAlSi 3 O 8 at 2000-4500 K and 0-30 GPa based on classical potentials. These compositions span the range of melt polymerization states in…
Two different preparations of biocompatible magnetic nanoparticles (MNPs), both (MnFe2O4 and Mn0.91Zn0.09Fe2O4) coated with methoxy polyethylene glycol aldehyde (m-PEG-CHO) were prepared through coprecipitation method. The prepared powder was reanalyzed for material structure with an X-ray diffractometer (XRD) and for…
Asparagus racemosus (AR) is a popular botanical present in several Ayurvedic medicines and nutritional and dietary supplements with immunomodulatory, galactogogue, and anticancer activity. A steroidal saponin known as shatavarin IV is one of the active constituents of AR. A new, selective, and rapid HPLC/MSIMS method…
Motivated by recent experiments revealing superconductivity in MoS$_2$, we investigate the Josephson effect in the monolayer MoS$_2$ at the presence of an exchange splitting. We show that the supercurrent reversal known as $0-\pi$ transition can occur by varying the doping via gate voltages. This is in contrast to com…
Studies on the phases of CuInP2S6 crystal exhibiting phase transitions of the order-disorder type are performed.
The structures of domain walls have been investigated by the method of three-dimensional computer simulation in films with uniaxial in-plane anisotropy at different film thicknesses. For the calculations, the parameters characteristic of permalloy films have been taken. It has been established that, depending on the f…
A novel kind of multi‐walled carbon nanotube (MWNT) spongiform adsorbent, with nickel Prussian‐blue analogue (NiPB) inside its porous surface was prepared. The carbon nanotube sponge (C/MWNTs) was equipped with large holes and a porous structure, and MWNTs were uniformly distributed in the porous surfaces. The optimal…
The interaction between amorphous and crystalline C 60 fullerene (20–40 wt %) after thermobaric treatment at temperatures of up to 630°C at a pressure of 70 MPa is studied by means of neutron diffraction. Amorphous fullerene is prepared via mechanical grinding. It is shown that a dense composite is formed with a densi…
The incorporation of nanoaluminum in an 86% solid composite propellant formulation poses processing problems when following conventional methods. Therefore, to accommodate an optimum percentage of nanoaluminum in such formulations, a new bicurative system was introduced. Summarizing in the present study, a bicurative…
The vibrating wire alignment technique is a method which, by measuring the spatial distribution of a magnetic field, can achieve very high alignment accuracy. The vibrating wire alignment technique can be applied to fiducializing magnets and the alignment of accelerator straight section components, and it is a necessa…
This paper presents a novel approach for realizing tactile sensors by integrating a piezoelectric polymer with a low voltage Organic Thin-Film Transistor (OTFT) on flexible plastic substrates. The transducing element consists of PVDF piezoelectric film. The proposed device architecture is similar to the extended gate…
Magnetite (Fe3O4) and core-shell iron/iron-oxide (Fe/FexOy) nanomaterials prepared by a cluster deposition system were irradiated with 5.5 MeV Si2+ions and the structures determined by X-ray diffraction as consisting of 100% magnetite and 36/64 wt% Fe/FeO, respectively. However, X-ray magnetic circular dichroism (XMCD…
A Broadband antenna realized by CPW-Fed antenna (coplanar waveguide), this is loaded with split ring resonator (SRR) as metamaterial unit cell. The aim of this work is to exhibit the improvement of the gain and the band width by metamaterial inclusion. The obtained results from HFSS simulation concerning the constitut…
A novel dual-stator bidirectional-flux modulated permanent magnet (PM) machine is presented in this paper. The key of the design is to locate consequent PM poles in both stator and rotor sides and the merit is that the magnetic flux produced by either the rotating or stationary PMs and dual-stator windings can be modu…
A sputter deposited CoPtCr-SiO2perpendicular recording media with excellent orientation was successfully grown on a thin polyamide film. Using 32-channel GMR tape heads and advanced hard-disk drive heads, the recording performance and durability of this media was investigated. These studies demonstrated an unprecedent…
A coupled-resonator structure consisting of a stub resonator and a nanodisk resonator is proposed and numerically investigated by using a two-dimensional finite element method. Simulation results show that two resonant modes occur in the transmission spectra, and the sharp and asymmetric Fano-lines increase with the w…
Substitution of carbonate has long been recognized in both synthetic and natural biologically and geologically precipitated forms of hydroxylapatite. Although the predominant substitution mechanism in all of the calcium members of the apatite group formed below 100 °C is substitution of carbonate for phosphate (B-type…
A homogeneous solution of the problem of semi-infinite shear crack along the interface between a thin layer and an elastic half-plane made of a material with different properties is obtained and studied. Under the assumption that the influence of normal shear stresses can be neglected, the problem is reduced to the Ri…
In this paper, we present a new material stack for planar Hall effect bridge (PHEB) sensors and a detailed investigation of the sensitivity and noise properties of PHEB sensors made from these. The sputter deposited material stack was based on a ferromagnetic (FM) NiFe sensing layer surrounded by two layers of anti-FM…
A series of Pd/C catalysts (2–4 wt % Pd) with different particle sizes of the supported metal was prepared under varied conditions of the formation and surface deposition of the polynuclear hydroxo complexes (PHCs) of palladium(II) on powdered Sibunit carbon supports with their subsequent reduction to the metal. It wa…
