Abstract: Heavy metals are widely used in a range of materials including paints, motor vehicles, guns, and electrical components. After discarding such materials, the metal ions after dissolution can penetrate to the environment and are toxic to plants, organisms, and humans. [..] Read more

Abstract: Breast cancer is the most commonly diagnosed cancer in women. Circulating tumor DNA (ctDNA) is related to breast cancer development and thus, screening of tumors using ctDNA blood detection is highly sensitive and may significantly improve early-stage breast tumor diagnosis. [..] Read more

Abstract: Flexible strain sensors based on MWCNTs/epoxy nanocomposite coated on a polyimide (Kapton HN) substrate are often preferred due to their outstanding properties. Nevertheless, polyimide has a poor adhesion with different classes of materials, such as ceramic, polymers and metals, caused by its hydrophobic nature and low specific surface energy. [..] 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: All metal products that operate under high loading conditions are subject to wear over time. Therefore, there is a need to restore the geometric shape of the working parts after the consumption of the product life. [..] 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: Galvanizing is an application of a zinc coating on the steel base material by electrolytic deposition. Zn coating protects anodically the base material (typically unalloyed or low-alloy steel) against corrosion. [..] 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: Increasing demands for reducing the surface roughness of components impose high requirements for finishing operations. As a result, it creates a space for the application of new progressive methods for the surface finishing of components. [..] Read more

Abstract: The spent auto catalytic converters are a valuable source of platinum group metals (PGM metals), such as platinum, palladium and rhodium. There are two main types of structures used in construction of catalytic converters –ceramic or metallic carrier. [..] Read more

Abstract: A number of domestic and foreign companies have long been struggling with the problem of storage and supply. Warehouses are an important part of the logistics chain as a link among the supplier, the manufacturer and the final consumer. [..] 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: 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: The paper presents analysis of phase transformation temperatures of 20MnCr5 steel. For calculations of required temperatures, i.e. [..] 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: 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 extensive studies in nanoscience in the last decades are dedicated to the development of new protocols for the preparation of nanoparticles (NPs) with controlled size and shape. The dimensions and steric parameters influence the reactivity, catalytic, electrical, and optical properties and define the application of NPs in various fields: catalysis, sensing, medicine, electronics, etc. [..] 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: Manganese ore fines generated during manganese production are either partially recycled as agglomerates using binders, or stored, leading to pollution, and negative environmental impacts due to landfilling. Fines have for long been considered as environmental unfriendly, loss if not recycled and stage threats in the metallurgical industry if not taken care of. [..] Read more

Abstract: Currently, the focus of the waste Li-ion battery processing is on better separation of individual material components of the batteries so that this process is as efficient as possible. This step is closely related to the success of the subsequent processing of the individual separated components. [..] Read more
