Abstract: Bioceramics, recognized for their exceptional bioactivity, have become integral in applications across medicine, surgery, dentistry, and tissue engineering. Their inherent biocompatibility, combined with both osteoconductive and osteoinductive properties, offers significant advantages over traditional graft materials in bone regeneration therapies.

Abstract: Superalloys based on Ni, Ni-Fe, and Co are among the most used metallic materials for high-temperature applications due to their excellent strength, creep and corrosion resistance. Co-based superalloys, in particular, offer superior corrosion resistance compared to Ni-based counterparts, making them ideal for long-lasting components subjected to moderate static or cyclic loads at elevated temperatures.

Abstract: This study investigates advanced composite materials consisting of a NiAl matrix reinforced with an FeSi phase, which are considered promising candidates for next-generation tool applications, with the potential to replace conventional high-speed steels alloyed with tungsten and cobalt. The alloys were synthesized via vacuum induction melting followed by centrifugal casting. [..] Read more

Abstract: High-entropy alloys (HEAs) have gained significant attention among researchers due to their exceptional mechanical properties (including high hardness, strength and wear resistance), corrosion and oxidation resistance. The combination of these properties, along with good thermal stability, enables a considerable range of potential applications for HEAs. [..] Read more

Abstract: Quantum computing is currently emerging as a useful paradigm for solving highly complex computational problems. Current quantum computers are unfortunately too noisy to provide sufficient accuracy, and quantum-classical hybrid algorithms emerged as a solution. [..] Read more

Abstract: The La-Ni binary system, and in particular the LaNi5 binary intermetallic phase, has been intensively studied in recent decades, especially as a promising hydrogen storage material. Knowledge of phase equilibria is very important for the possible optimization of material properties. [..] 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

Abstract: The Neural-Network Quantum States (NNQS) method is rapidly emerging as a powerful tool for investigating quantum many-body physics. By combining variational Monte Carlo techniques with neural network-based variational functions, this approach leverages the remarkable advancements in deep learning achieved in recent years.

Abstract: The South African ferroalloy industry faces increasing environmental pressures to transition toward sustainable metallurgical practices. Traditional smelting relies heavily on fossil-based reductants and fluxing agents, contributing significantly to carbon emissions. [..] Read more

Abstract: For finished products, it is sometimes necessary to measure hardness with minimal surface disturbance, where the indentations should not be visible to the naked eye. Applied loads that meet this requirement are below 0.9807 N for common metals. [..] Read more

Abstract: In the current socio-economic context, where demographics, public policies, internationalization, and other factors have brought major changes to higher education institutions, these institutions must increasingly adopt concepts and practices from the business environment to position themselves competitively in the market. Mergers between educational and research institutions thus represent an effective method for creating stronger entities and increasing regional influence by diversifying activities and gaining access to new resources and/or technologies that can provide competitive advantages.

Abstract: The circular economy provides a sustainable approach to tackling growing environmental challenges, particularly in waste management and resource depletion. This paper explores the role of circular economy objectives by converting waste into valuable products such as fuels, chemicals, and bioplastics. [..] Read more

Abstract: Pyrolysis technology represents a viable strategy for the conversion of waste into valuable fuels and products, which remains a core tenet of the circular economy. Notably, higher temperatures, corrosive environment, and mechanical stresses warrant careful material selection in constructing reactors in order to ensure operational efficiency and durability.

Abstract: This study explores aluminum casting processes' efficiency, focusing on comparing automated and semi-automated systems. Key factors such as productivity, quality, cost, and flexibility are examined to highlight the strengths and limitations of each approach. [..] Read more

Abstract: The study aimed to present a model for the analysis of internal conditions and key factors for the competitiveness of a foundry, taking into account the principles of the Toyota quality system and development variables. The model was based on a modification of the BOST method and its practical implications were tested. [..] Read more

Abstract: The metallurgical industry, which is key to the economy, dynamically combines tradition with modernity, striving for profitability and innovation. In the context of sustainable development, the aim of the article is to develop a six-stage model for improving metallurgical products, taking into account quality, environmental impact and costs.
