Abstract: This study investigated the stabilization of cadmium sulfide (CdS) nanoparticles in aqueous solutions of the triblock copolymer Pluronic P123. The concentration of the added cadmium sulfide varied between 0.002 and 0.02 M. [..] Read more

Abstract: Composite nanofiber materials offer advanced properties and functions applicable in many fields, especially in medicine. Nowadays, these materials are mainly fabricated using the DC electrospinning technology with multi-spinnerets electrodes designed for such purpose. [..] Read more

Abstract: In the paper the results of investigation of drawing method including simple drawing and shear by computer simulation were presented. The simulation in Deform program was performed. [..] Read more

Abstract: Due to the specific requirements for monitoring processes and products in the aircraft industry, non-destructive testing (NDT) is increasingly used in combination with advanced statistical analysis.The paper presents the results of research aimed at determining the quality of wax models and multi-layered ceramic forms, used for precise casting of critical parts of aircraft engines. Studies on the shape and dimensions of wax models and ceramic moulds were made by 3D scanning using the GOM ATOS CORE 200 scanner. [..] Read more

Abstract: The article describes the state of the art computer simulation in the field of metal forming processes the main problem points of traditional methods were identified. The method, that allows predict the deformation distribution in the volume of deformable metal with taking into account of microstructure behavioral characteristics in deformation load conditions, was described. [..] Read more

Abstract: Since the use of cold-rolled steel sections is a standard method in mechanical engineering and steelwork and cost efficiency is always a big issue, it is of great interest to address the highly non convex problem of cross-section optimisation. At a first glance classic genetic algorithms already seem to be suitable for this problem, because they are powerful search heuristics for solutions in non convex problems. [..] Read more

Abstract: Although the requirements on quality of products are increasing, most companies still pays little attention to product quality planning. Furthest in this direction they are automotive suppliers, which include most of metallurgical companies, which use quality planning methodologies developed for this industry area and which must within the framework of production part approval process submit evidence about successful products and processes quality planning.

Abstract: The present study was conducted to identify simultaneously economic, environmental and social conditions that should be considered when deciding to cooperate with the supplier. This integrated approach allowed, besides identifying the validity of individual criteria, noting the relationship among a group of economic, social and environmental criteria. [..] Read more

Abstract: In this study magnesium based composite AX41 reinforced with short Al2O3 fibers were investigated. In-situ neutron diffraction has been applied to study deformation mechanisms under compressive deformation. [..] Read more

Abstract: One of the main problems companies have to solve is the distribution of resources among the potential beneficiaries. In many cases, this problem can be presented as a linear programming task with a linear objective function and constraining conditions. [..] Read more

Abstract: Light extraction (LE) efficiency of GaN buffer layer was studied by angle-resolved photoluminescence. We measured enhancement of light extraction efficiency (LEE) up to 154% by introducing the SiNx layer atop the GaN buffer and subsequent GaN light extraction layer (LEL) overgrowth. [..] Read more

Abstract: With growing pressure for wide application of silver nanoparticles, the methods of their production have become increasingly important. Moreover, repurposing waste has been a globally acknowledged trend in the context of circular economy approaches in recent decades. [..] Read more

Abstract: Al-Si alloys alloyed with Mn and Mg are widely used in industry, especially as cast alloys. The presence of Mg allows subsequent heat treatment, which will improve mechanical properties. [..] Read more

Abstract: The aim of the article is to show the use of artificial intelligence in improving the heating process in continuous industrial furnaces. To improve the heating in continuous furnaces, heating control based on models that consider the dimensions, material, and heating method can be used. [..] Read more

Abstract: This paper present the issue of plasma treatment of the surface of polypropylene (PP) using AgO+CuO coatings in order to antimicrobial activity. The analyzed coatings were deposited using High Power Impulse Magnetron Sputtering (HPIMS). [..] Read more

Abstract: In the last years, immiscible alloys have gained significant attention, mainly due to the use of their immiscible nature for the preparation of new advanced multiphase alloys. Most of these alloys are based on the Cu-Fe system. [..] Read more

Abstract: Duplex steels are an austenitic-ferritic type of stainless steel. They have better mechanical strength, corrosion resistance, and fatigue strength in aggressive environments compared to traditional stainless steels in the food industry such as AISI 316 or 304. [..] Read more

Abstract: The article presents results of tests concerning the metal-mineral abrasive wear resistance of arc-sprayed coatings with lower and higher air pressure (larger and smaller drops of metal) and HVOF-sprayed coatings deposited using the self-shielded flux cored wire providing the obtainment of the weld deposit of high-chromium cast iron Fe15 (in accordance with EN 14700). The significance of influence of the spraying technologies on abrasion resistance was determined using a completely randomized design. [..] Read more

Abstract: In this study, the reaction mechanisms of gold nanoparticles (AuNPs) synthesis using dialdehyde cellulose (DAC) and dialdehyde hyaluronate (DAH), and their covalent binding to chitosan nanofibers (CHITs), was investigated. The synthesis uses a redox reaction where dialdehyde polysaccharides are oxidized to dicarboxy polysaccharides and the gold salt precursor is reduced to elemental gold. [..] Read more

Abstract: Arthrospira platensis (spirulina) is known for its high biological activity, including antioxidant, anti-inflammatory, and antiviral properties. In recent years, spirulina polysaccharides have been actively researched in fields such as tissue engineering, targeted drug delivery, and wound healing. [..] Read more
