Load characteristics are the main factor to affect voltage stability. In addition, load modeling reflecting the actual load characteristics has been a well-known difficult problem and unsolved so far, It is mainly due to the fact that the load composition, amount and characteristics are always changing. This paper int…
This study investigated how doping by iodine or gallium affects processes associated with current carriers by undertaking a kinetics investigation of electron loss processes in the CdTe samples prepared by direct ampoule method. Owing to these processes, the current carriers generated by light can be trapped or recomb…
The attempt to study magnetism in (n,m) chiral space of single-walled carbon nanotubes (SWNTs) with embedded metal cluster is presented. Co13 metallic cluster inside zigzag and chiral single-walled nanotubes was investigated using density functional theory (DFT). Magnetic properties of the endohedral nanotubes with th…
We present a simple Monte Carlo study of orientational ordering in a nematic liquid crystal with embedded chiral nanostructures. The nanostructures are shown to impose bulk chiral order in the nematic only for large enough values of the chiral pitch.
We have evaluated the mixing performance of a microreactor with inline ultraviolet (UV) and Fourier transform-infrared (FT-IR) measurement. We performed the well-known Villermaux–Dushman reaction with inline and offline UV measurements. Absorbance was continuously reproduced at each flow rate with inline measurement.…
Transmission electron microscopy, X-ray diffraction and electrical resistivity have been observed for annealed Fe/Si core–shell clusters and their assemblies in comparison with those for annealed Fe and Si clusters. Fe clusters are wholly oxidized, where voids are formed in the central regions. Si clusters are not who…
Jute nanofibers were prepared by treating jute fibers with chemical pretreatments then applying blender finishing. Scanning electron microscopy (SEM) observations revealed that the structure of the jute fibers changed significantly after 20 times blender. Field emission scanning electron microscopy(FE-SEM) images show…
Lightweight materials are getting more and more attraction towards their use in automobiles, planes, protective structures, electronics and supports for numerous benefits ranging from reduction in fuel consumption in vehicles to lighter and stronger in protective structures. For efficient use of materials in applicati…
Two kinds of modified activated carbons were prepared by dipping with Zn(NO3)2 solution and by reducing in the atmosphere of N2 at high temperature respectively, which were characterized by FTIR,DSC,SEM and EDS. The surface structure was strongly changed in the process, along with the changes of chemical functional gr…

In this study, we compared the UV-protective abilities of the europium complex compared to titanium dioxide, which represents the most common physical filter for ultraviolet light in the broad-band spectral range. The UV absorption and light transformative capacities of the europium complex were evaluated using a spec…
Calculation of Plasma internal inductance (li) is essential in Tokamak plasma research. Much more plasma parameters such as the plasma current density profile, magnetohydrodynamics instability, and plasma energy confinement time can be determined by using this parameter. Discrete poloidal magnetic probes along with th…
Abstract A simple perforation prediction model which describes the size of the hole created in a thin metallic plate is presented and compared to hypervelocity impact experiments. The new mechanics model is based on the 1959 Charters model, but takes into account the initial compressive wave on impact by replacing the…
We successfully fabricated (chitosan/alginate) (CHI/ALG) multilayer thin film by layer-by-layer (LBL) method. Film durability was enhanced by forming cross-linking using heat treatment, glutaraldehyde, and calcium chloride. Indeed, the adsorption of fibrinogen onto CHI/ALG multilayer thin film was determined by QCM sy…
Six new alkaline-earth metal carboxyphosphonates [Mg(H2O)(H2PMIDA)] (1), [Sr(H2O)(H2PMIDA)] (2), [Sr2(H2O)(PMIDA)] (3), [Sr2(HPO4)(H2PMIDA)] (4), [Ba2(HPO4)(H2PMIDA)] (5), and [Ba2(H2O)(H2PMIDA)2] (6) (H4PMIDA = N-(phosphonomethyl)iminodiacetic acid) have been synthesized solvothermally in order to study the coordinat…
First principles calculations have been carried out to investigate the crystal structure, elastic constants, chemical bonding, electronic and optical properties of Li2CdGeS4. The calculated equilibrium lattice constants, bulk modulus and its pressure derivative are in reasonable agreement with the available experiment…

For graphene placed in a dc magnetic field and exposed to two electromagnetic waves of the same polarization but different frequencies, an expression for the direct current density in a direction perpendicular to the polarization plane of the waves is derived. The direct current component is nonzero for the wave frequ…
Microbial depolymerization processes of polyethylene glycol are analyzed by numerical simulation. The weight distribution after cultivation of microorganisms for two and four days was used to solve an inverse problem for the molecular factor of the degradation rate. Numerical results are compared with experimental res…
Nitrogen implantation in Interstitial-Free steel was evaluated for its impact on metal transfer and 1100 Al rider wear. It was determined that nitrogen implantation reduced metal transfer in a trend that increased with dose; the Archard wear coefficient reductions of two orders of magnitude were achieved using a dose…
