Abstract: Nanofibrous matrices represent an attractive material for biomedical applications – mainly due to their high specific surface and small pore size, which make them interesting material for drug delivery matrixes construction. Besides the morphological characteristics, the surface functionality strongly affects the drug-matrix interaction, drug conjugation and drug release kinetics. [..] Read more

Abstract: To model the quantitative relationship of the nanoparticle toxicity we can use theoretical molecular descriptors or physico-chemical characteristics. The former provide an auspicious interpretation of the toxicity mechanisms, however their computation may be very demanding, namely in the nanoscale. [..] Read more

Abstract: The intended operation time prolongation of the key components of fossil-fuelled power plants working in the creep conditions over 200,000 or even 250,000 hours (far beyond their original design lifetime) must be accompanied by thorough and extensive monitoring of the current material state and particularly creep damage. The extent of cavitation damage is routinely tested in-situ by using replica method and its quantification is based on a practice stated in VGB-TW 507, NORDTEST NT TR 170 or NORDTEST NT TR 302 that further develop the original Neubauer's classification.

Abstract: The paper describes combination of optical and electronic methods together with IR analysis for evaluation of the paint coatings. Based on these methods the fingerprint of each paint layers is identified according to requirements of ISO 12944-9. [..] Read more

Abstract: Thermal spraying technology today belongs to manufacturing technologies that significantly reduce production costs while achieving high utility performance. The paper focuses on the methodology of testing of selected technological tests, especially bending and twist tests, metallography and porosity analysis of layers made by HVOF technology.

Abstract: Coke is one of the basic energy sources in the blast furnace process. Its quality essentially then determines the course of the blast furnace process. [..] Read more

Abstract: Control chart is the basic tool of the statistical process control (SPC). It aims to an early detection of errors in the process and thereby ensures compliance with the required level of stability. [..] Read more

Abstract: Nowadays one of the most important global issues in the heavy industry and specially in metallurgical sector is the allocation of carbon dioxide emission allowances. The equity in allocation of emission allowances is discussed offend with this problematic. [..] Read more

Abstract: The paper presents experimental results of diameter reduction in tubes with the angle of flare α=300. Tube diameter reduction was performed on the WPM-120 cold profile eccentric rolling machine. [..] Read more

Abstract: Titanium and its alloys are promising materials in the dental filed because they have good biocompatibility, corrosion resistance and physical and mechanical properties. For that reason, they have many applications as crowns, inlays, bridges, dental implants etc. [..] Read more

Abstract: Active thermography is a method for nondestructive inspection of materials. This contribution presents quantitative inspection of coating thickness by flash-pulse thermographic inspection and apparent thermal effusivity based evaluation. [..] Read more

Abstract: Galvanizing still plays an important role in surface treatments. The thickness and quality of the zinc layer is the basic monitored property of materials treated in this way. [..] Read more

Abstract: The boronizing is a thermochemical process in which the boron atoms are introduced into the steel surfaces. This study evaluates the fracture toughness of boride layers developed by powder boronizing of high-chromium steels Sleipner, K 190, Royalloy, Sverker 21 and Sverker 3. [..] Read more

Abstract: AlCoCrFeNi2.1 alloy belongs to a group of materials called eutectic high-entropy alloys (EHEAs). These have gained attention due to the fact that there is no so-called "strength ductility trade-off". [..] Read more

Abstract: Industrial branches are developing the best materials for their applications. An important part of surface engineering is represented by Physical Vapor Deposition (PVD) and Thermal Spraying techniques. [..] Read more

Abstract: Reinforced concrete service-life depends on a transport rate of corrosion stimulators, especially chlorides, towards the reinforcement through concrete cover layer. Traditional migration tests are able to state the effective diffusion coefficient; however they do not provide the information about the microstructure and its development in time. [..] Read more

Abstract: Paper presents the results of investigation regarding the influence of additional processing after oxy-acetylene cutting on the structure and corrosion resistance of the zinc coating. Research was focused on fittings for overhead power lines – a double eyes links type SLINK. [..] Read more

Abstract: The actual theme is study of immunity corrosion - proof steels used in food industry against corrosive environment of washing agents. The experimental work samples were used with two types of surface of the blade. [..] Read more

Abstract: The corrosion resistance of widely used X50CrMnNiNbN21-9 high-alloyed austenite valve steel, in three different combustion gases have been compared. The comparison was performed on the basis of results of kinetic corrosion of the tested steel in combustion gases from propane-butane, gasoline with 5 and 10 % of ethanol additives (v/v) and fuel oil with 5 and 10 % of FAME additives (v/v).
