Abstract: In recent years, nanoparticles have high importance in various areas such as biomedical, environmental or pharmaceutical applications due to their chemical and physical properties. In all these applications, maintaining control over the particle size and shape is of high significance due to their size and shape-dependent properties. [..] Read more

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 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 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: 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 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: 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: 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
