This paper studies the mechanical properties of polyethylene (PE)-Single-walled carbon nanotube (SWCNT) complexes by using density functional theory (DFT). At the PBE/SVP level, the Young's modulus of the complexes is obtained as a function of PE content. It is established that, with increasing number of PE chains attached to the SWCNTs, the Young's modulus monotonically decreases. The density of states (DOS) results show that no orbital hybridization exists between the PE chains and nanotubes. The results of this work are of importance for the design of composite materials employing SWCNTs. © 2016 World Scientific Publishing Company. Source

The possibility of industrial production of stabilized cold-finished steel is considered. The correlation between the maximum distortion of cold-finished rods and the residual tensile stress is established. To improve the geometric stability of cold-finished rolled steel, additional microreduction of the cold-deformed metal is proposed. © 2015, Allerton Press, Inc. Source

A technology for firing vermiculite conglomerates with a high content of inert material is examined. The firing operation is completed in an additional “zero” module by the internal heat accumulated in the conglomerate itself. Heat is transferred by radiation from particles of the inert material to the vermiculite granules inside the conglomerate. At the same time, heat is being transferred by conduction from the outer layers of the granules to their inner layers. Such a method of using recuperated heat makes it possible to mitigate the temperature regime of the electric modules, reduce the consumption of electric power, and decrease the energy content of the process. © 2016, Springer Science+Business Media New York.

We develop an approach for constructing continuous solutions of integral Volterra equations of the first kind that arise in modeling developing dynamical systems. We give existence theorems for the solutions and study their asymptotic behavior. Theoretical results are illustrated with numerical computations on test examples. © 2014 Pleiades Publishing, Ltd.

Results are presented from theoretical and experimental studies of modular-pouring electric furnaces. The process of the absorption of heat energy by vermiculite was examined and the optical-geometric parameters of the firing modules were determined. Efficient values were found for the temperature and duration of the firing of vermiculite concentrates. It is shown that the existing modular-pouring electric furnaces can be improved and new, energy-saving furnaces of this type can be developed. © 2015 Springer Science+Business Media New York Source
