In Belgorod Shukhov State Technological University, instead of the previously used Barium-Iron-Serpentine (IBS) concrete designed Iron-Magnetite-Serpentine (IMS) concrete reinforced with nano-tubular chrysotile and organized its industrial production. We calculated and made the new heavy concrete on the base ordinary…
Abstract: A passive direct methanol fuel cell was fabricated and investigated experimentally to study the characteristics of the open circuit voltages under the variation of some operating parameters such as cell orientation, cell temperature and also methanol concentration. Then the effect of cell orientation on the…
In this paper the friction wear characteristics of vinylester and vinylester composites have been investigated under dry and water lubricated sliding conditions, under different applied normal load and sliding speed. The experiments have been carried on a pin on disc arrangement at normal temperature conditions. The r…
This paper deals with the extraction of small object positions in the scanning electron microscope (SEM). An approach based on line scanning and new object tracking approaches are presented and evaluated for their capabilities to reliably track objects in the SEM when the objects are moving quickly. Image acquisition…
of titanium implants has been a large focus of recent research. Thermal oxidation is a technique used to diuse oxygen into the surface of a material. This process forms an oxide layer. By varying the thermal oxidation temperature, the crystal structure of the TiO2 layer can be changed from anatase to rutile at tempera…
Chalcogenide glasses based on sulfide, selenide and telluride alloys in binary or multi-component systems are very promising materials for various optical and photonic applications in the spectral range 0.6 to 15 mm. These glasses are being studied mostly for applications as passive devices but these glasses are also…
This paper proposes a general applicable numerical technique for the simulation of three-dimensional (3D) electrode shape changes obtained during the electroplating processes. The shape of the electrode is found displacing each mesh node proportional with, and in the direction of the local current density according to…
The world is facing declining liquid fuel reserves at a time when energy demand is exploding. As the supply decreases and costs rise, In or- der to achieve a secure and stable energy supply that does not cause environmental damage, renewable energy sources must be explored and pro- mis-ing technologies should be devel…
Since the introduction of nanotechnology there has been an increase in the use of nanoparticles (NPs) in the development of biosensors for the detection of bacterial pathogens. Consequently, research exploring their potential toxicity has also increased as some have been shown to be harmful depending on their size, sh…
Research on the flow field in the fibre-converging zone is always the emphasis and difficulty of compact spinning. Therefore in this work numerical studies on the three-dimensional flow field in four-roller compact spinning with a guiding device were carried out using Fluent software. First a three-dimensional physica…
Low temperature wafer bonding is a crucial technology for micro-electro- mechanical systems (MEMS) and silicon-on-insulator (SOI) materials. Interface bond quality is closely related to the surface adhesion energy and nanoscale surface morphology. In this paper, low temperature atmospheric-pressure plasma source was u…
The first Cr:ZnS laser mode-locked by graphene-based saturable absorber mirror generates the shortest reported sofar mid-IR pulses of only 5.5 optical cycles (44 fs ) at 2.35 µm with 139 nm spectral bandwidth.
The present work incorporates the study of efficiency of WO 3 for photocatalytic degradation of Azure B dye. Effect of some factors such as catalyst dose, concentration of dye, intensity of light, pH etc., on degradation of the dye was examined. The experimental data prove that the reaction follows pseudo first order…
Waste papers such as old newspaper, waste paper chunks or any other paper products can be used for the production of fuel Ethyl Levulinate which can be used as an additive to the biodiesel. The utilization of the ethanol as an additive to the diesel leads to some specific problems due to the difference in their chemic…
If thorium (Th) is to make a near-term contribution to the nuclear fleet, an open-cycle LWR may be economically preferable. There has been recent interest in using Th in closed-cycle reduced-moderation BWRs (RBWRs). However, there remain significant reprocessing and fabrication challenges to multi-recycle of Th. Thor…
Anthropogenic activities due to increased urbanization and industrialization has polluted the geoenvironment and ground water resources. A healthier environment therefore warrants efficient containment system that can effectively contain harmful waste for a long duration of time. Clay liners and its contaminant retent…
The formation mechanism of the LPSO structures of Mg–Zn–Y alloys has been investigated by the energetic assessments with the first principles calculations. For the key players of the LPSO structures, the stacking faults and the solute elements of Zn and Y, two scenarios are proposed; one is the stacking fault control…
The ballistic behavior of four different armor ceramic materials with thicknesses varying from 3 mm to 14 mm has been investigated. These are two types of alumina Al2O3 armor grades and two types of SiC armor grades produced by different armor ceramic producers. The ballistic study has been performed using the standar…

Magnetic and electronic properties of Cu1−xFexO systems with x = 6.25% and 12.5% have been investigated using first principles calculations. The ground state of CuO is an antiferromagnetic insulator. At x = 6.25%, Cu1−xFexO systems with Fe on 2 and 4 substitution positions are half-metallic due to the strong hybridiza…
