Abstract: In recent years, there has been an increased interest in technologies for the production of titanium ceramic materials with properties, the level of which in terms of price-quality ratio exceeds the level of similar materials based on other metals. The strength of the bond with the metal in modern titanium ceramic products corresponds to the level of cermet systems based on noble metals or alloys without them. [..] Read more

Abstract: This work is focused on studying the antimicrobial effect of silver nanoparticles made by green synthesis. For the green synthesis, extracts from Salvia officinalis were used. [..] Read more

Abstract: Nanoindentation has become a popular tool for the exploration of mechanical properties of materials at the nanoscale. However, calibration and traceability issues are often neglected, making the direct comparison of results between different instruments difficult. [..] Read more

Abstract: In our study, we aimed to synthesize superparamagnetic nanoparticles (PMPs) able to isolate and immobilize and thus preconcentrate flavonoids for subsequent analysis. We report the optimal conditions such as different pH of Britton Robinson buffer, temperature and time of incubation on the isolation of different types of flavonoids, such as Genkwanin and Pratol from extracts of freshwater algae.

Abstract: Here we report the optimal conditions for the isolation of reduced glutathione (GSH) and oxidized glutathione (GSSG) from various types of matrix, such as blood, plasma or cells and their characterization using ion-exchange liquid chromatography with VIS detector. In our study, we aimed to synthesize paramagnetic microparticles able to isolate and immobilize GSH, GSSG from blood or plasma and thus preconcentrate it for subsequent analysis on ion-exchange liquid chromatography with VIS detector.

Abstract: Biocompatible and bactericidal coatings were deposited onto different titanium based implant materials. For this the plasma chemical oxidation (PCO) process as well as the atmospheric pressure plasma chemical vapour deposition (APCVD) was used successively. [..] Read more

Abstract: The aim of this work was study molecular and quantitative analysis of metal ion binding to humic acids (HAs). The object of our study were two various samples of HAs. [..] Read more

Abstract: Many parts for automobiles and home electric appliances are made of steel sheets. In sheet metal forming processes, the knowledge of technological values, such as yield or tensile strength and r-value, enables a more precise control of processes and results in many benefits such as an improvement in yield efficiency in machining processes and a decrease in loss of material.

Abstract: The article presents the results of the milling tests - "hard machining" - on the processed (hardened and tempered) material X37CrMoV5-1 (ČSN 19552). At the beginning, the hardness tests of the machined material block were carried out using the Rockwell method. [..] Read more

Abstract: This paper presents actual computational possibilities and experiences from the modelling of qualitative parameters of continuously cast steel billets in ProCAST simulation software achieved during a solving of research projects with industrial partners. The ProCAST simulation programme is a part of the equipment of the “Laboratory of modelling of processes in liquid and solid phases” of the “Regional Materials Science and Technology Centre” at the Faculty of Metallurgy and Materials Engineering at the VŠB – Technical University of Ostrava.

Abstract: The evaluation of quality of metal impeller using selected quality instruments was the main purpose of this paper. The analysis of non-conformances of metal impeller, which is a part of in-line fan, is presented. [..] Read more

Abstract: The paper provides a qualitative analysis of the proposal to introduce SWIBŻ into creation of Polish Port Community System. The key information from SWIBŻ system would be widely used by national and international administration institutions in order to achieve expected level of shipping monitoring and control.

Abstract: Lightweight is one of methods for low-carbon design. Based on the lightweight applications potential of metal composite bulks and on the fact that the interface between metals is externally visible currently, this study aims to investigate the feasibility to create core-shell type metal composite bulks.

Abstract: The problem of current freight transport lies in a plenty of smaller shipments that are delivered daily to the same collection points. Consumers and Distribution centers have found the possibility to reduce the amount of money in stock if they order only those goods that they are able to sell in a short time. [..] Read more

Abstract: The paper sets an example of modeling the expansion and bed pressure drop of the cohesive and problematic material - titanium dioxide modified by Aerosil R972 in program Ansys / CFX - Fluent using two multiphase models, Euler Fluid-Granular Model and Dense Discrete Phase Model at certain predefined conditions in a square section fluidized bed cell. The variables bed pressure drop, particle concentration in volume and velocity field of solid particles were defined for the simulations in metallurgical processes.The research follows on from the previous study of simulating the arrangement of spherical particles with a diameter of 2-10 mm and compares them with the experiment, where it was discovered, that the square section fluidized cell achieves the best results with spherical particle arrangements of diameter 8 mm..

Abstract: Steels dusts from electrostatic processes, which are currently a problem in the ecological sense, is a rich but problematic carrier of many elements such as Fe, Zn, Mn, Cr. The existing recycling technologies, unfortunately, do not allow for their full recovery. [..] Read more

Abstract: Mechanical properties of steel workpiece are often evaluated based on its hardness. For quenched and tempered steels, hardness can be predicted based on quenching and tempering processing parameters. [..] Read more

Abstract: The interaction between light and matter can be significantly enhanced through the excitation of surface plasmons and related nanospace-restricted focusing of light energy. The local enhancement of light energy is especially pronounced in the case of so-called plasmonic hotspots, which have found wide application in surface-enhanced Raman spectroscopy (SERS).
