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: Nowadays nanomaterials are widely used in industry, medicine, cosmetics, remediation of persistent pollutants, and therefore it is important to test their possible harmful effects on both human health and environment. However, nanoparticles can be often contaminated by bacterial endotoxins (lipopolysaccharides, pyrogens) that can cause false positive results of the (eco)toxicological tests. [..] Read more

Abstract: Recent advances in Nano-biotechnology, offer potential longer duration storage options for silver nanoparticles (SNPs) with preferable capping agents where a plentiful efforts have been given to minimize the toxicity effects SNPs. To overcome the toxicity scenario of SNPs, a novel green methodology was put forward in the present investigation. [..] 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: 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: Hard particles used in combination with iron-based matrix are applied in a wide range of areas. It is used for screw conveyors, de-baler knives or mining gear teeth. [..] Read more

Abstract: Due to the reduction in production costs, not only in the automotive industry, more and more sandwich-structure parts are emerging to replace expensive, technologically complex elements such as cooling rotors in electrical installations. They are required to meet a complex set of attributes – resistance to abrasive wear, anti-corrosion requirements, and especially manufacturing costs.This article discusses and compares the mechanical properties of a critical part (cooling rotor) made as a sandwich structure of aluminum alloys and nickel-phosphorus (NiP) coatings.The specific mechanical and corrosive properties of the thin NiP film vary with the percentage of phosphorus and the heat treatment.

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: This paper aimed to investigate the advantages of the use of S700MC steel instead of St52 steel widely used in industrial areas. For this purpose, a tensile test, a macro hardness test, a Charpy impact test, and a fatigue life test were performed on St52 steel and S700MC steel specimens. [..] 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: This article presents a method for software assessing the level of axial segregation in wire rod. This so-called axial segregation is routinely determined visually as dark spots on the etched cross-section of wire, which classifies comparison to a etalon. [..] 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: Eco-efficiency analysis development with life cycle approach for steel production will be discussed in the paper. Eco-efficiency analysis is a tool for quantifying the relationship between economic value of technology or product and environmental impacts over the entire life cycle. [..] 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 article deals with tribological evaluation of surface properties and their changes in biodegradable material PLA (polylactic acid). On samples prepared using 3D FFF printing technology, with uneven filling density, printed on the Prusa printer. [..] 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
