Based on microscopic (exciton) theory of optical properties of symmetrically perturbed ultrathin molecular films, the absorption, reflection and transparency indices were formulated and presented in the function of frequencies of external electromagnetic field in near IR region. It has been showed that all optical properties depend o...

Nanometalic materials are at the present moment the most commercialized class of nanomaterials. Methods for their synthesis and exploitation of the physical phenomena of their behaviour on atomic level are ever-expanding. Their prices are sometimes too high and in lowering the price, finding the new recourses of raw materials, would ...

Research focus of this paper are stresses in concrete, reinforcement and tendons, cracks and deflections of the prestressed girders of “Type A” in order to optimize the span of such girder for the same amount of tendons and reinforcing steel. Serviceability Limit State (SLS) is a condition in which construction ceases to ...

For the development of refractory coatings with controlled rheological properties the influence of micronized milling process was investigated. Change the properties of fillers based on cordierite, primarily on changing the size and shape of grain fillers, dispersion and stability of the suspension of the coating was investigated, al...

Water that is commonly used for drinking is groundwater, that appears on the surface of the Earth's crust as sources of different types and capacities, and in most cases that water is chemical, physical and bacteriological acceptable and suitable for use. In some cases, there is some blurring of water, that is the result of heavy rainfall or some h...

In this work we studied the response of newly developed armored steel plates PROTAC 500 to the ballistic testing with armored piercing bullets with a core of tungsten carbide, charge 7.62 mm. Interactions between the bullets and the steel plate was investigated by standard metallographic and mechanical testing methods. We were interested in the geo...

Innovative idea of the device for detecting microstructure changes, concept and construction was carried out and controlled by authors of this article in cooperation with Slovenian industry. Since the electrical resistance is one of the most structurally sensitive properties of the materials, we used its measurement to detect microstructural change...

This paper describes the analysis and rationalization of energy consumption in gray iron foundry CIMOS TMD Casting Zenica. Based on results of analysis the key points are defined rationalized and measures proposed to reduce energy consumption, and therefore reduce production costs. The most significant share of energy consumption, and therefore in ...
