On-Board Supercapacitor Energy Storage: Sizing ConsiderationsThe paper considers the problem of choosing the optimum size for on-board energy storage system (ESS) based on supercapacitors (SCs) taking into account both the braking energy and the braking power of an electrical vehicle. The authors have derived equation…
The paper is dealt with the study of the distribution of epiphyton algae on higher aquatic plants of various ecological groups in water bodies of Kiev. It has been found that the most favorable conditions for their development are formed on submerged plants, where the number of algae species and their infraspecific ta…
The merit assessment of the nuclear hydrogen steelmaking (NHS) was performed for reduction of CO2 emissions from the steelmaking process which accounts for approximately 14% of the total emissions in Japan. The NHS process is composed of the steelmaking process by hydrogen reduction and hydrogen production process usi…
In order to investigate the relationship of oxide-ion conduction between the brownmillerite-type and perovskite-type structures, the solid solution system Ba2In2-x(Zn1/2Zr1/2)xO5 was investigated. The orthorhombic phase was obtained in the range of 0.0≤x≤0.3, while the cubic phase was obtained in the range, 0.4≤x≤2.0.…
The goal of this work is to model the heterogeneous recombination of atomic oxygen on silica surfaces, which is of interest for accurately predicting the heating on vehicles traveling at hypersonic velocities. This is accomplished by creating a finite rate catalytic model, which describes recombination from an atomist…
The groundwater of Fourchi which feeds the town of Ain M’lila in the Eastern region of Algeria is derived from limestone. This water have a hardness of 87 ¡ F and give rise to compact and adherent deposits of calcium carbonate in the drinking water distribution network. To inhibit the furring of this water some chemic…
During postulated high-pressure core melt accident scenarios, temperature values of more than 800°C can be reached in the reactor coolant line and the surge line of a pressurised water reactor (PWR), before the bottom of the reactor pressure vessel experiences a significant temperature increase due to core melting. Fo…
A problem exists with a part produced by forging made by Shultz Steel of Ti-6Al-4V in the variance of properties throughout the part. There is one specific region that exhibits the most variance. The purpose of the report is to determine any microstructural differences within the region of interest in the part. When m…
The transport properties of a 5-mm-wide practical PLD-GdBa 2 Cu 3 O y (GdBCO) coated conductor, which has a 100 m thickness copper stabilizer, was evaluated. Critical currents were measured up to 600 A in magnetic fields (parallel and perpendicular to the conductor surface) up to 12 T and in a temperature range of 4.2…
It is currently accepted that success in implant-supported restorations is based not only on osseointegration, but also on achieving the esthetic outcome of natural teeth and healthy soft tissues. The socalled "pink esthetic" has become the main challenge with implant-supported rehabilitations in the anterior area. Th…
The First-order Reversal Curve (FORC) method is employed to analyze the influence of intermolecular interactions and particle size effect on Light-induced Thermal Hysteresis (LITH) behaviour of 1D spin crossover systems. We have used atom-phonon coupling model in order to simulate LITH-FORC diagrams with different int…
We have investigated the H2 molecular adsorption on the Ag(111) surfaces. To treat van der Waals (vdW) interaction accurately, we performed first principles calculation based on spin-polarized density functional theory (DFT) with the semiempirical correction term of vdW interaction. We got the value of 36.0 meV as the…
The cobalt(II) complex [Co(tta) 2 (H 2 O) 2 ] (3) was prepared by the reaction of [Co(OAc) 2 ·4H 2 O] (2) (OAc = O 2 CMe) with two equivalents of 1-(2-Thenoyl)-3,3,3-trifluoroacetone (H-tta, 1). Replacement of the aqua ligands in 3 was possible by addition of methanol giving [Co(tta) 2 (HOMe) 2 ] (4). On gentle heatin…
Nutraceutical cocrystals are emerging as novel crystalline forms to modify physicochemical properties of pharmaceuticals. In general, various methods of cocrystal preparation including their applicability to nutraceutical are described. Crystal engineering of nutraceuticals can, produce cocrystals and is expected to b…
Purpose: Light microscope with polarized light has been used for observation layered zone, visible thanks to polarization of the light, inside polymer-polymer composites and nanocomposites Aim of work has been concentrated on investigation of nanocomposites as promising engineering materials, basing on composition of…
Abstract in UndeterminedAn interlaboratory study on measurement of evaporative resistance (Ret) with thermal manikins has been conducted in order to assess the repeatability and reproducibility limits as a function of mean resistance values, when using similar test protocols (ASTM F2370). Three independent laboratorie…
Multipolar order in complex fluids is described by statistical correlations. This paper presents a novel dynamical approach, which accounts for microscopic effects on the order parameter space. Indeed, the order parameter field is replaced by a statistical distribution function that is carried by the fluid flow. Inspi…
The results of X-ray diffraction study of a new promising magnetoelectric composite films with alternating layers of barium strontium titanate and bismuth ferrite with layer thicknesses d = 6–200 nm are presented. All films show epitaxial growth on the MgO single crystals substrates. The 00L profiles for thick layered…
"NiFe2 O4 nanoparticles have been prepared by sol-gel autocombustion technique, some of them have been supported in SiO2 following the TEOS technique. Particle formation and structural and magnetic properties were investigated by using X-ray diffraction, scanning electron microscopy (SEM) and magnetization measurement…
