study the surface morphology, crystallinity and chemical composition of the as grown antimony film [ 10 ]. The grown film was further tested for radiation detection. The photoresponse of the film was evaluated using its current-voltage characteristics.

1 Introduction Glass-ceramics are polycrystalline solids, partially crystalline and partially amorphous. Due to the presence of both crystalline and residual glassy phase, glass-ceramics possess a combination of valuable properties of both glasses and ceramics [1] . Glass-ceramics have gain importance in recent years due to their remarkable dielectric, structural, mechanical [2] and biocompatible properties [3] which find application in various fields of telecommunication [4] , architecture [5] , and health care [6] . The physical and chemical

1 Introduction Recent progress in material science is possible due to access to advanced and complex diagnostic tools and methods. Enabling a new measurement methodologies may allow to improve the investigation procedures in terms of accuracy, speed and costs. One of the most common tests of materials, is verification of the influence of environmental conditions. One can list a number of procedures defined in the standards in order to observe the deterioration caused by the simulated solar light (i.e. PN-EN 60068-2-5:2011) as well as changing temperature

many others, due to their excellent physical and chemical properties [ 1 – 7 ]. Polymers are easy to manufacture and they are characterized by low density, flexibility and cost-effectiveness [ 8 ]. Desired surface properties of polymers such as hydrophilicity, roughness, crystallinity or conductivity are required for their successful application [ 2 , 3 ]. On the other hand, they are often unsuitable to use due to their low surface energy leading to poor wettability, adhesion, print-ability and scratch-resistance [ 1 , 8 , 9 ]. For these reasons, surface of

physical properties. They do not differ significantly in shapes, as shown in the SEM images, however, the fibers have different colors. Mechanical strength of the fibers doped with metallic particles (PAN Ag and PAN Au ) during static stretching was not worse than that of undoped fibers (PAN). The examination of metallic nanoparticles doped fibers showed the presence of these substances in the samples. Analysis of EDS tests showed that despite using the same amounts of the metal ions precursors, the amount of silver in the element-doped fiber was significantly greater

important role in long-term reliability problems [ 1 ]. Among different methods of titanium thin film preparation, including physical vapor deposition, plasma focus, chemical vapor deposition, electrochemical and chemical nitriding, sputtering, and ion implantation [ 1 , 5 - 17 ], direct-current (DC) magnetron sputtering is a simple and most appropriate method. However, the mechanical properties and crystallographic structure of titanium thin film in this method are strongly dependent on process parameters such as sputtering power, substrate temperature and sputtering
