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: This paper describes experiments for the development of methods of non-destructive, non-contact surface diagnostics. This is oriented on technical systems in metallurgical operations with usage of laser scanners and digital image processing techniques. [..] 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: 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: 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: The key characteristic of austenitic Hadfield´s steel is its toughening (hardening) under mechanical loading (during operation). By the influence of mechanical loading austenite transformed to martensite, resulting in surface hardening (curing) with a good toughness. [..] 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: The operation of a blast furnace is characterized by simultaneous running chemical and physical processes. Hence, the influence of parameters like pressure, temperature and gas composition on the reduction behaviour of the iron bearing minerals cannot easily be presented in a simplified form, e.g. [..] 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: The aim of this article is to identify the main risks in internal logistics processes in companies involved in metallurgical supply chains. The article also includes an initial proposal on how to work with and eliminate some risks. [..] 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
