Abstract: Hylocomium splendens, species of moss frequently used for biomonitoring purposes, was subjected to metal oxide nanoparticle suspensions (nano-TiO2, nano-ZnO) in known concentrations in order to assess its applicability in biomonitoring of metal oxide nanoparticle pollution. After weekly subjecting the samples of the moss to the suspensions for up to eight weeks, the samples were digested and the metal content was analyzed by ICP-AES. [..] Read more

Abstract: The presented paper contains the results of research on fractal analysis. The fractal analysis was carried out on X39Cr13 steel subjected to heat, surface and thermo-chemical treatments. [..] Read more

Abstract: Nd-Fe-B permanent magnets are key materials in the electric power system and they are indispensable for the future success of environmentally beneficial technologies. The hysteretic characteristics of sintered Nd-Fe-B magnets are highly sensitive to their microstructure and composition of phases. [..] Read more

Abstract: Thanks to its unique properties such as high melting point and density, tungsten and tungsten-based alloys are commonly used in a wide range of applications. Among others, these materials are promising candidates for the plasma facing components in the future fusion reactors. [..] Read more

Abstract: The purpose of the article is to investigate artificial neural network ANN use in due-date assignment DDA for standard products in the real-life small batch and multi assortment make-to-order production company. The research was conducted with the historical data and resulted in the ANN aided DDA encoded into the company ERP system. [..] Read more

Abstract: The paper presents an example of the solution of transport management and organization in the quarry in terms of material flow requirements and machine efficiency. Raw material transport is a very important technological process in the quarry. [..] Read more

Abstract: The paper is devoted to a discussion of the results obtained by the simultaneous use of three methods of thermal analysis in three different specialized devices with the aim to precise solidus and liquidus temperatures. The low carbon as-cast steel (130 mm round format) from Continuous Casting Machine No. [..] Read more

Abstract: Due to the efficient combination of a forming step with a consecutive heat treatment, hot-stamping has become an established technology for the production of high strength steel parts in the automotive industry. In the beginning, sheets are heated above austenitisation temperature and held in order to obtain a fully austenised microstructure, then formed and instantly quenched in the forming tool.

Abstract: In this article, the intensity of mold metal reactions between ceramic shell and magnesium alloy AZ91E is studied. The two possible protective gasses used for melt protection are studied - SF6 (sulphur hexafluoride) and 3M NOVEC 612. [..] Read more

Abstract: The paper presents analysis of phase transformation temperatures of 20MnCr5 steel. For calculations of required temperatures, i.e. [..] Read more

Abstract: The submitted article deals with the study of casting and solidification of a 12 t ingot made of structural steel 42CrMo4 using numerical simulations in the THERCAST® and MAGMASOFT® software. The possibilities of each individual software in filling and solidification of steel were assessed, including the prediction of ingot defects such as porosity, shrinkage cavities or shrinkage porosities; the proportion of liquid phase, segregation of selected elements and solidification time were also monitored.. [..] Read more

Abstract: Nanofibrous materials are currently in transition between laboratory and industrial-scale production. The main factor that hinders transition speed is relatively low productivity compared to widely used technologies such as melt-blown or force-spinning. [..] Read more

Abstract: In this paper, results of our running work on a sensitive and efficient detection of phosphates are presented. We develop a testing kit for rapid chemical detection based on surface-enhanced Raman scattering (SERS). [..] Read more

Abstract: Increasing the efficiency of processes in warehouse facilities is now required in every industry. One of the important decision-making problems is the proper utilization of storage space. [..] Read more

Abstract: The article deals with new technology for the production of a flat nanofibrous structure using AC electrospinning and the development of a new type of spinning electrode. Simulations of the distribution of the electric field around the electrode were performed. [..] Read more

Abstract: Gold nanoparticles (AuNPs) find application in various areas depending on their properties, shape and size distribution, which are mainly influenced by the preparation conditions. Moreover, due to the trend in recent years, toxic reducing and stabilizing agents are being abandoned during the synthesis of AuNPs, and alternative substances for one-pot green synthesis are being sought. [..] Read more

Abstract: The aim of this work is to study the changes in the properties of Polylactic acid (PLA) fabrics after plasma treatment at atmospheric pressure. Volume dielectric barrier discharge (VDBD) and diffuse coplanar surface barrier discharge (DCSBD) were applied to modify the PLA surface in ambient air using exposure times 1 -10s. [..] Read more
