The paper presents the strength tests results of joints made by use of different fusible adhesives on ethylenevinylacetate (EVA) basis. Four non-metallic materials were bonded, namely plywood of two different thicknesses and spruce, and pine wood. From plywood sheet the test specimens of dimensions 25x100 mm were cut…
This paper adresses the bending behaviour of individual multi-filament yarns for use in textile forming analyses. Yarn specimens deform nonlinearly under their own weight in a cantilever configuration. a relation between the applied moment and the resulting curvature is established. Numerical simulations are performed…
The microstructural characteristics of the hot-worked and subsequently tempered tool steel grade X38CrMoV5-1 was studied as a function of the cooling rate using transmission electron microscopy and three-dimensional atom probe. According to the continuous cooling transformation diagram different cooling rates were cho…
Multiple-hydrogen trapping by mono-vacancies in tungsten was investigated based upon the first-principle (density functional) calculation. An equilibrium thermodynamic model is presented to describe a bulk tungsten crystal containing the mono-vacancies and hydrogen atoms by taking account of the first-principle calcul…
The preparation of soft leathers from chondrichthyes fish such as stingray is unfamiliar to tanners processing conventional animal skins. The dorsal portion of stingray skins with calcified denticles has a very attractive and beautiful appearance. Due to calcification of the skeleton, stingray skin is very hard and to…
Syntactic foams as building materials are studied. Various manufacturing parameters contributing to syntactic foam composition in relation with the ‘pre-mould’ method were identified and inter-related. An equation based on lattice unit cell models with the minimum inter-microsphere distance concept for a relation betw…
In recent years, photovoltaic systems have gained worldwide recognition and popularity as a environmentally friendly way of solving energetic problems. However, a problem of utilizing worn out photovoltaic systems, amount of which will rapidly increase in the future, is yet to be solved. Establishing a technology of r…
The verification of a transformer model for the repre- sentation of transient behaviors such inrush and ringdown is not trivial as several parameters may influence measurements and simulations. The purpose of this paper is to suggest a laboratory testing strategy and to present an enhanced transformer model. A special…

Self-Oriented Ca3Co4O9 Thin Film as an Anode Material for Enhanced Cycling Stability of Lithium-Ion Batteries, Zhu, Xue-Bin, Chou, Shu-Lei, Wang, Lin, Li, Qi, Shi, Dong-Qi, Wang, Jia-Zhao, Chen, Zhi-Xin, Sun, Yu-Ping, Liu, Hua-Kun, Dou, Shi-Xue
In-situ TEM (transmission electron microscopy) of silver nanoparticle ink at high temperature was carried out. Into a carbon film tube coating the spiral tungsten filament which was attached to the TEM specimen holder, a silver nanoparticle ink was injected. After evaporation, silver nanoparticles with an aggregated s…
Purpose: In the following paper there have been the structure and complex of mechanical properties of magnesium alloys presented which requires very often knowledge of elastic-plastic properties at elevated temperatures. These properties are connected with microstructure that is influenced by metallurgical and technol…
The Navy has a need to measure temperatures at critical areas on large caliber gun inner bore surfaces to insure appropriate action is taken in case of a misfire. Inappropriate actions could result in the loss of life and the disabling of a naval warship. In this report we describe the development of an ultrasonic‐bas…
During the past decade polylactide acid (PLA) polymer has been the subject of numerous researches aimed at comparing it with traditional petroleum based polymers for many packaging applications. PLA is biodegradable and derived from agricultural by-products such as corn starch or other starch-rich substances like maiz…
Surface Plasmon Resonance (SPR) nanosensor has become an increasingly exploited technology for detection and analysis of chemical and biological compounds. Silver (Ag) nanostructured film fabricated by thermolysis method is shown to exhibit a strong Localized Surface Plasmon Resonance (LSPR) at wavelength around 400 n…

To identify the ionic conductivity mechanism of Nb + 5 -substituted La 2 Mo 2 O 9 , an ion dynamic study on these substituted materials has been performed. Although the ionic conductivity and mechanism of conduction has already been reported, the ion dynamic study of these materials has scarcely been carried out to es…
The hardness, planing, and moulding properties of tamarack wood from natural forests were evaluated on kiln-dried specimens following three types of drying schedules: high temperature, elevated temperature, and conventional. Hardness tests were conducted according to the ASTM D143 standard. Planing and moulding proper…
Misfit dislocation structures at twist-grain boundary and its effect on grain boundary strength are investigated by using molecular dynamics simulation with EAM potential. The results reveal that the density of misfit dislocations which are formed on small angle twist-grain boundary is increased as the twist angle inc…
