These days, composite materials successfully substitute the traditional materials due to its various significant applications. This paper examines the influence of fiber orientation and fiber length on electrical properties of PALF reinforced Bisphenol-A composite and explores the potential of using PALF as reinforcin…
The paper investigates the process of variation of magnesium oxychloride cement deformations at the initial hardening stage depending on the activity of magnesium oxide powder which is determined by the parameters of the source material burning. Investigation is focused on magnesium cements obtained from pure magnesiu…
This introductory chapter presents an overview of the history of the gaseous hydrocarbons, including that of acetylene, which is the focus of the current volume. The isolation, synthesis, and applications of these species is presented, along with an introduction to the polymerization of unsaturated hydrocarbons. These…
Bismuth doped cobalt ferrite nanoparticles have been prepared by sol-gel auto combustion method. An attempt has been made to study the electrical and magnetic transport properties of CoBixFe2-xO4 nanoparticles. The phase identification and morphological studies have been carried out by X-ray diffraction (XRD) and fiel…
Since the high-Tc superconductivity in iron-based superconductors was found in 2008, numerous new iron-based superconductors have been discovered. Of them, FeSe-based superconductors receive the most attention due to their unique properties. Here, we briefly introduce the structure and physical properties of two newly…
Yttrium oxide was synthesized by wet chemical route and calcined at various temperatures. On x-ray diffraction analysis of the material using Williamson-Hall analysis followed by Rietveld analysis indicates that the powder exists in nano crystallite size with lattice strain. The spherical harmonics analysis model of m…
This paper is concerned with efficient representations and approximations of the solution to the scattering problem by a system of strongly coupled plasmonic particles. Three schemes are developed: the first is the resonant expansion which uses the resonant modes of the system of particles computed by a conformal tran…
A new planktonic pennate diatom species, Stauroneis guslyakovii Genkal et Yarushina, sp. nov., was described from the Yamal and Tazovsky peninsulas using a scanning electron microscope. The new species is morphologically similar to S. gracilior and S. francisci-josefi, but differs from them in number of striae and are…
intro_obj: Los trasplantes de tejidos compuestos sufren rechazo crónico modulado entre otros factores por citoquinas. El quimerismo reverso o quimerismo del aloinjerto se define como la repoblación del tejido trasplantado por células circulantes del receptor. Plerixafor produce la movilización de células madre de médu…
This paper deals mainly with two types of new materials namely SA213T23, SA213T92 with specialemphasis on dissimilar combinations due to its advantages in production welding of super heater tubes mainly in tube to tube joints and tube to header joints. Welding was carried out under manual TIG process with argongass hi…
The paper presents the methodology and results of a numerical simulation of coupled thermal and electrical phenomena in a thermoelectric (Te) cooler module obtained with the mOOse framework released by Idaho national laboratory. The coupled system of partial differential equations is solved for the value of electric p…
Structural integrity of reactor pressure vessel (RPV) in light water reactors (LWR) is of highest importance regarding operation safety and lifetime. The fracture behaviour of low-alloy RPV steels with different dynamic strain aging (DSA) & environmental assisted cracking (EAC) susceptibilities in simulated LWR enviro…
Under consideration is the composite based on the epoxy resin filled with 7 nm silicon dioxide and aluminum oxide nanoparticles. The model of dependence of the elastic modulus of the polymer heterogeneous material on the filler concentration has been plotted regarding the interphase layer characteristics. The dependen…
Spherical TiO 2 /RuO 2 particles were synthesized by ultrasonic spray pyrolysis (USP) at 200 and 800°C. The activity for the oxygen and chlorine evolution reactions (OER and CER, respectively) and the dynamic responses from electrochemical impedance spectroscopy (EIS) of the USP powders, as well as of the correspondin…
Avoiding the use of templates and employing natural minerals as raw materials could promote the cost-efficient preparation of mesoporous materials. This work demonstrated a template-free route to process natural halloysite into mesoporous silica with high specific surface area (SSA) up to 767 m 2 /g and pore size of a…
The paper contains the results of testing of compressive members reinforced longitudinally and transversally with steel and GFRP reinforcement. The spacing of transverse reinforcement (stirrups) and longitudinal reinforcement ratio varied in the specimens. The stress-strain, stress-Poisson’s ration, stress-volumetric…
Flower-like ZnO micro/nanostructures were synthesized via a simple reflux route without addition of surfactant. The characterization of as-synthesized ZnO sample was performed using X-ray diffraction, field-emission scanning electron microscopy and photoluminescence spectroscopy. The activity of the as-synthesized pho…
A three-dimensional micromechanical model including thermo-mechanical relaxation constitutive equation for multidimensional flow is developed to describe dynamic deformation of metals. Parameters of the thermo-mechanical model are found for the aluminium alloy. Test calculations are carried out for homogeneous and pol…
