The p-Cu₂O/i-ZnO nanorods/n-IGZO heterojunctions were fabricated by electrochemical and sputtering method. ZnO nanorods were grown on conductive indium gallium zinc oxide (IGZO) thin film and then p-Cu₂O layer was deposited on ZnO nanorods to form the heterojunction. ZnO nanorods play an important role in carrier tran…
Post-harvest tomato plants were used to manufacturefireboards by thermopressing. Four plant materials were investigated: exhausted tomato plants ground to 5-10 mm (PHTr), tomato (PHT) and maize (PHM) plants ground to <0.5 mm, composted tomato plants (CPHT). These materials had significantly different chemical composit…
To investigate energy gap bowing in homogeneously alloyed CdS x Se 1−x quantum dots (QDs) and to understand whether it is different from bulk, we perform density functional theory based electronic structure calculations for spherical QDs of different compositions x (0 ≤ x ≤ 1) and of varying sizes (2.2 to 4.6 nm).
The synthesis and properties of four aza boron pyridyl-isoindoline analogues that differ in the position of fused benzene ring annelation on the pyridyl moiety is reported.
This paper describes the development and testing of a 1 kW reversible solid oxide fuel cell intended for energy storage on space exploration missions, particularly for long term Mars exploration. The energy is stored as H2 or CO produced by electrolysis of H2O or CO2. The reactants are then converted back to its origi…
Polypyrrole (PPY) coatings doped with sulphuric, oxalic and phosphoric acid were prepared on 304 stainless steel (304SS) by electropolymerization. Surface morphology and anti-corrosive performance of the polymer film was investigated by scanning electron microscope and electrochemical tests. The results indicate that…
The article considers the applying of CDIO approach elements in Industrial University of Tyumen to bachelor students of “Urban Civil Engineering and Municipal Facilities” and “Water Supply and Sewage” departments, direction “Civil Engineering”. The authors analyzed in detail the methods of lessons conducting by CDIO S…
In this study, the storage characteristics of high-amylose rice gel and emulsified rice gel, two intermediate food materials, were investigated. High-amylose rice was gelatinized and sheared at a high speed to create rice gel. Cooking oil was added to the rice gel and the mixture was mixed at a high speed to create em…
The paper describes the problem of steel pipes corrosion in domestic hot water supply systems. A case study of abnormally high rate of corrosion of galvanized steel pipes in a hot water supply system, installed in a complex of residential and public buildings, was considered. The rapid corrosion led to premature failu…
Er3+ doped zinc phosphate glasses with chemical compositions (60-x) NH4H2PO4 + 20ZnO+10BaF2+10NaF+xRE (where RE=Er2O3, x = 0.1, 0.5, 1.0, 1.5 and 2.0 mol%) have been prepared by melt quenching technique. Amorphous structure was ascertained by XRD analysis. The functional bands have been assigned and clearly elucidated…
We report the photocatalytic activity of reduced graphene oxide cadmium sulfide (RGO-CdS) composite towards the degradation of 4-Nitrophenol (4-NP) under simulated solar light illumination. The solution processable RGO-CdS composite was synthesized by one pot single step low cost solvothermal process, where the reduct…
Y2O3:Eu3+ and Ca-doped Y2O3:Eu3+ luminescent particles have been synthesized via poly-ol method and subsequent annealing at 800°C. From powder X-ray diffraction pattern it is confirmed that Ca2+ ion gets incorporated into Y2O3 lattice. Photoluminescence properties of these samples are studied by luminescence excitatio…
Catalytic reactions are generally catalyzed by metal nanoparticles, metal oxides, or their bi- or trimetallic forms with various formulations, morphology, composition, and shapes. The metal nanoparticle catalytic performances are directly related to the surface features of particles such as crystal structure, atomic s…
In this study, the microstructure and dielectric and magnetic properties of a lanthanum-doped yttrium copper titanate ceramic (YLCTO) are reported and have been discussed.
Surface modification of multi-walled carbon nanotubes (MWCNTs) was carried out by introducing mixture of concentrated sulphuric acid and nitric acid by ultrasonication process. The pristine and surface modified MWCNTs were characterized by X-ray diffraction (XRD), Fourier Transform Infrared (FT-IR), Raman spectroscopy…
Camphor is a renewable carbon source that can be used as raw material for synthesizing Carbon Nanotube (CNT). Camphor is a substance that can be found on the Cinnamomum camphora tree. In this research, the method used to synthesize Aligned Carbon Nanotube (ACNT) from camphor is Floating Catalyst Chemical Vapor Deposit…
The article considers the interaction of prestressed load-bearing strut-framed systems for buildings and constructions, which is exposed to the influence of vibrodynamic loads from moving vehicles. The mechanical and mathematical models of calculation and software for their implementation were designed taking into acc…
A challenging barrier for the broad, successful implementation of Reversible Solid Oxide Fuel Cell (RSOFC) technology for Mars application utilizing CO2 from the Martian atmosphere as primary reactant, remains the long term stability by the effective control and minimization of degradation resulting from carbon built…
The aim of this work is to develop and characterize new materials with height properties, especially foams based on copper, obtained by powder metallurgy techniques using a NaCl space holder. The shock resistance (impact energy absorbed) and porosity measurements were carried out. The foams were investigated by optica…
The skirts of four coke drums of a delayed coker plant in an oil refinery became severely cracked as result of the service and a poor design. The cracks were located in the circumference just below the welded joint of the skirt with the pressure vessel of the coke drums. Since the cracks grew up to one hundred percent…
