The nanoscale C60 and some of its doped derivatives with some elements of group III and Vwas performed byDensity Functional Theory. EHOMO, ELUMO, energy gap (AE), and those parameters that give valuable information about the reactive behavior: the ionization potential (IP), electron affinities (EA), chemical potential…
In this work describe new method receipt composition material AL-SI-FE system. For describe the composition material used the method of power metallurgical. As source material are used technically pure Al and Si, as well as steel 1008. Source powder mingled from correlation 59 %Al-9 %Si-32 %Fe. 2 stage compaction with…
The electronic structure and properties of the osmaabenzenes and para substituted osmabenzenes have been explored using the hybrid density functional mpw1pw91 theory. Systematic studies on the substituent effect in para substituted osmabenzenes complexes have been studied. The following substituents were taken into co…
The “special” nature of the copolymerisation of higher N-alkyl acrylamides of different structure with n-dodecyl acrylate or n-docecyl methacrylate in butyl acetate or toluene is shown. It has been found that the compositional inhomogeneity of the obtained copolymers is determined by the overall initial monomer concen…
The experimental research of high-cycle fatigue alloy VJ-159 under high-temperature loading are presented. A variant of the damage accumulation model suggested, taking into account the main factors affecting the high-cycle strength of structural materials. The results of numerical simulation the experimental sample an…
The paper considers modeling an aramide fiber woven composite. The experimental study has been done, including statistic tests, dynamic tests using Kolsky method with the Split Hopkinson Bar, and ballistic impact tests. A reduced model of a woven composite is constructed that would considerably reduce the computationa…
The study obtained the ratios for describing of bending deformation of reinforced walls-beams with different accuracy, from which the classical Tymoshenko theory and both Bernoulli theory are follow as particular cases. On the example of study of mechanical behavior of hinge supported beam it is shown that for the non…
The removal and determination of toxic heavy metal ions in aqueous solutions has been given much more attention over the past few years.In this paper, a removal and separation/preconcentration method for cadmium species on Poly S 15 -g-EMA 100 (a kind of polystyrene-graft-ethyl methacrylate copolymer) in water samples…
Astir casting processwas used to fabricate aluminumcomposites reinforced with various volume fractions of 2, 4, 6, and 8 wt%rice husk ash (RHA) and silicon carbide (SiC) particulates in equal proportions. The study was undertaken to investigate the ageing response of the aluminum alloy (A356.2) when dispersed with RHA…
The organic/inorganic hybrid coatings have been intensively studied in recent years and it have been reported that the incorporation of inorganic components enhanced both the corrosion resistance and adhesion of organic coatings.The UV radiation has been widely used to cure coating resins for many years.The UV-curing…
Ru nanoparticles have been deposited onto a multi-walled carbon nanotube paper (Ru@MWCNTP) via a wet chemical method. The resulting catalyst, Ru@MWCNTP has been demonstrated to significantly reduce the charge overpotentials of the Li–O2 battery at a current density of 500 mA g−1. The reversible formation and decomposi…
Comparative analysis of the results of physical and computer modeling of pressure welding of coarse-grained HN58MBYUD heat-resistant nickel alloy using ultrafine-grained gasket is presented. According to the results of numerical simulation of the stress strain state, maximal values of strain are observed in the periph…
(APS) as an oxidant in the aqueous medium,and nanofibers produced by electrospinning . Electrospun nanofiber mats were by treated heat under air atmosphere to be stabilized. Nanofiber production from AN-IA copolymers and suitability of the nanofiber as carbon nanofiber precursor is discussed. Copolymer are characteriz…
Burn marks are serious defects that can occur during injection molding, and from the viewpoint of the molding engineer, are a problem that urgently needs to be solved. In the present study, a gas collection and component analysis system was used to determine the gas production mechanism during injection molding of PBT…

Origami, the Japanese art of paper folding, has seen a recent shift from a traditional art form to a platform for design of structures capable of actuation.These structures are capable of reconfiguration into multiple defined geometric states by rotation about pre-defined lines in a grid.Thus far, research in the orig…
Water borne acrylamide based curing agents were prepared from acrylamide, formalin and methanol. The curing agents were characterized for their various physico-chemical characteristics. High performance coatings based on water compatible epoxies and above curing agent were than prepared by blending them in a various r…
In order to routinely operate the LHC with 25 ns bunch spacing during Run 2,\nelectron cloud effects will have to be mitigated through beam induced scrubbing.\nTherefore, the Run 1 experience with 25 ns beams will be reviewed and used for\ndefining the most effective scrubbing strategy. In particular, the potential of…
It has been highlighted the importance of huntite/hydromagnesite mineral as an innocent flame retardantmaterial in the plastics in our previous works. In this study, flame retardant behaviors of huntite and hydromagnesite in the polymeric dye coatings were obtained and thesize dependence of this circumstance has been…
