Abstract: The 13th Five-Year Plan for Economic and Social Development of People’s Republic of China lasted from 2016 to 2020. During the period, Chinese steel enterprises have maintained the status of “high yield, high inventory, high cost”. [..] Read more

Abstract: In the global metallurgical industry, the volume of products produced is currently growing, and there is also pressure to reduce input costs while evenly increasing output quality and occupational safety. One of the ways, in which this can be achieved is to focus on the correct measurement of individual process variables already during the technological process. [..] Read more

Abstract: The aim of this study is to analyze the potential of decarbonization of steel production in Slovakia and Czech Republic. The study examines the European CO2 emissions policy, steel production trends, and the European emission trading system (EU ETS) allowances and emissions of Slovakia and Czech Republic steel producers.

Abstract: Changing market conditions, the emergence of new technologies and new solutions make it necessary to introduce changes in enterprises. One of the changes that enterprises have to face is Revolution 4.0, also known as industry 4.0. [..] Read more

Abstract: A large variety of types of rotation mechanisms used in mechanical engineering requires the designers of such machines to be able to select appropriate methods of their calculation. An important issue in the design of these mechanisms is to define the basic characteristics of these devices as well as areas of application. [..] Read more

Abstract: Currently, manufacturing companies operate in difficult market conditions. The demand for specific products depends on many factors, including mainly meeting customer requirements by the offered goods. [..] Read more

Abstract: One of the basic factors influencing the good results of any production system is the optimal organization of the production process so that the use of machines is as effective as possible. One of the methods of assessing the use of machine working time is the PAMCO (Project Analysis and Monitoring Company) method. [..] Read more

Abstract: Microwave plasma-based gas-phase synthesis of graphene and its derivatives represents a simple, environmentally friendly, and easily scalable production method enabling emerging large-scale applications. Microwave plasma decomposition of organic precursors, hydrocarbons, and alcohols, forms a high-temperature environment, where the process of catalyst-free dehydrogenation and consequent formation C atoms and C2 molecules leads to the nucleation and growth of high-quality few-layer graphene nanosheets. [..] Read more

Abstract: We have performed a quantum-mechanical study of two ferrimagnetic Ni2MnSn structures, a stoichiometric one with Mn-Ni swaps and an off-stoichiometric (Ni7Mn8Sn1) alloy. We used 16-atom supercells with the atomic positions related to those in the full Heusler structure, i.e. [..] Read more

Abstract: MXenes have drawn considerable attention in the past decade, thanks to their attractive properties such as metallic conductivity and surface hydrophilicity. While MXenes form highly stable dispersions in water, it can act as a limitation for certain applications such as photoactive layer in photovoltaic devices. [..] Read more

Abstract: Sea balls (pillae marinae) were impregnated with diammonium hydrogen phosphate (DAHP), carbonized, and activated using carbon dioxide or steam. Thus, activated carbon fibers (ACFs) with unique morphology and specific surfaces of 243 m2 g-1 were produced. [..] Read more

Abstract: GaN-based nanostructures are used for many present semiconductor devices. The main topics are structures for blue LEDs and LDs, but there are also other interesting and important GaN devices namely for power electronics, scintillators and detectors as well as High Electron Mobility Transistors (HEMT). [..] Read more

Abstract: Plasma spraying of liquid feedstocks allows deposition of materials with novel microstructures. Due to the combination of a liquid carrier and ultrafine powders (in case of suspensions) or in-situ formation of the final material in the plasma jet (in case of solutions), preparation of ultrafine composites is possible, typically in a form of coatings on the substrates. [..] Read more

Abstract: Nanofiber membranes are made of synthetic polymers mainly by electrospinning technology. The key point for creating a functional nanofiber membrane for water and air filters is to meet basic key properties such as filtration efficiency, mechanical resistance, and resistance to fouling and chemicals. [..] Read more

Abstract: High entropy alloys (HEAs) are multicomponent materials with at least five elements close to the equiatomic ratio. The multielement composition leads to many effects that stabilize solid solution phases instead of intermetallic compounds. [..] Read more

Abstract: In this work, two-dimensional layered material Ti3C2TX MXene has been used to immobilize enzyme sarcosine oxidase to fabricate a nanostructured biosensor. The device was applied for detection of sarcosine, a potential prostate cancer biomarker, in urine samples for the first time. [..] Read more

Abstract: In the present study, the anti-bacterial and mechanical properties of the ZrN/Cu nanostructured coatings were studied. Copper was introduced as the anti-bacterial agent owing to its substantial activity against bacteria. [..] Read more

Abstract: With the development of new technologies, the requirements for safety and health at workplaces are also increasing. One of these sectors are also industrial plants which process or use fine and ultrafine particles (<2.5 μm) during their activities or where these particles are created unintentionally as a by-product of the production processes. [..] Read more

Abstract: Developing and exploiting applications of functional nanomaterials often require colloidal nanoparticles with defined properties. Their production suffers from batch-to-batch variability as well as poor shelf life, and distributors demand high prices. [..] Read more

Abstract: Zinc oxide nanoparticles have been synthesized using non-thermal atmospheric pressure plasma (ZnO-NTP). We investigated the behavior of these ligand-free as a colloid suspension using different solvents, from deionized water to physiological saline and microbial culture broth. [..] Read more
