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: Our main objective was to determine the antimicrobial effects of selenium nanoparticles (SeNPs). For the testing of their influence we exploited isolates obtained from swabs from patients (n = 25) with hard-to-heal skin infections. [..] Read more

Abstract: The article deals with the issue of wastes from the predominantly imported raw material sources of drawn high-carbon and low-carbon wire. The acquired knowledge is based on an analysis in a selected spectrum of branches and disciplines dealing with the processing of wire and wire products in the conditions of the Czech Republic. [..] 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: This paper is dedicated to financial performance evaluation of metallurgy industry of the Czech Republic. Financial performance of the industry or company is a random process, which can be decomposed into the particular indicators. [..] Read more

Abstract: At the present time, the heat treatment process plays an important role in the production of automobile parts. This is valid especially for the transmission components. [..] Read more

Abstract: Fluxes (slag-forming additives) provide the formation of blast-furnace slag of suitable chemical composition. These additives affect not only the technological parameters of the blast-furnace process. [..] Read more

Abstract: Most manufacturing companies realize its technologies, implemented through concrete machinery parts. They differ in terms of importance, the relevance of their selection and the level of their modernity. [..] 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: The quality of ore raw materials significantly affects the technological aspects of the blast furnace process. The comparison of iron ores is complicated because of the wide range of parameters which can be used to evaluate the ores. [..] Read more

Abstract: The use of working time of a Samp drawing machine has been assessed in the article. It has been evaluated in the process of drawing a steel wire, φ = 1.5 mm in diameter, which is applied in civil engineering. [..] 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: Electrospun PLCL nanofibrous materials produced by direct current (DC) or alternating current (AC) electrospinning are good candidates for absorbable reinforcement for cardiovascular surgery composite bandages. For an appropriate description of the fiber layers and prediction of its relevant biomechanical characteristics, the knowledge of fiber orientation in the electrospun layers is essential.

Abstract: The AlSi10Mg alloy is widely used to produce complex-shaped components by Laser-based Powder Bed Fusion (L-PBF); these parts, characterized by light structures and high specific strength, are currently employed in high-performance room temperature applications in the automotive and aerospace industries. However, it is important to increase the data concerning the high-temperature mechanical properties of the L-PBF AlSi10Mg alloy to spread its use. [..] Read more

Abstract: Ti-6Al-4V alloy is mostly used for dental and hard tissue implants, due to its high strength to weight ratio, high corrosion resistance, and relatively low elastic modulus. However, apart from health concerns of V ions release and higher Young’s modulus (~120 GPa) than human bone (~30 GPa), recent research indicates day-to-day cyclic loading instead of a single-load event such as a fall, might be the consequence of inherent stiffness of fixation implants. [..] Read more

Abstract: Steel reinforcement of concrete structures is normally passivated due to high pH value of concrete interstitial electrolyte (pH 13-14). However, chloride contamination (e.g. [..] 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). [..] Read more

Abstract: Supercritical water (SCW) is a promising medium with a broad spectrum of potential applications in the industry. However, the absence of appropriate structural material able to withstand the severe corrosive conditions of SCW still limits its utilization. [..] Read more

Abstract: In study the effect of the of Nd-(Fe,Co)-B particles biencapsulation method on bonded magnetic material atmospheric corrosion behavior has been evaluated. Bonded magnets were prepared from Nd12Fe77Co5B6 magnetic powder after biencaspsulation. [..] Read more

Abstract: The trend to use modern materials and technologies in the development and construction of rail vehicles leads to testing new suitable alternatives for surface treatment of strain parts. Within the research project, suitable thermally sprayed coatings as alternatives for former surface treatment of selected components of rail vehicles are tested. [..] Read more
