This keynote talk will be devoted to describe hexagonal Cu2S p-type semiconductor thin film fabrication using DC magnetron sputtering. Nanofilms with thickness gradient were successfully deposited by taking advantage of the deposition geometry and target dimensions. X-ray diffrac [....] » Read More
Ge-rich Ge-Sb-Te (GGST) alloys are already integrated into the complementary-metal-oxide-semiconductor (CMOS) technology for industrial phase-change random access memory (PCRAM) production. This new type of memories allowing low-power system on-chip production and in-memory [....] » Read More
Nowadays, additive manufacturing (AM) has revolutionized many industries, including medical devices. It allows for the design of individualized and complex structures tailored to specific patient needs, while reducing costs and production time. In particular, Fused Filament Fabri [....] » Read More
Diffusive processes in dense multi-component mixtures should be described with special concentration-dependent terms. Traditional systems of diffusion equations with constant matrices either ignore interaction between the mixture components (when the diffusion matrix is diagonal) [....] » Read More
The rapid evolution of composite materials—ranging from natural fiber composites (NFCs) and polymer composites (PCs) to metal matrix composites (MMCs)—has spurred a growing need for accurate, efficient, and non-destructive characterization techniques. Traditional expe [....] » Read More
Piezoelectric materials play a pivotal role in the advancement of biomedical sensing and actuation systems due to their intrinsic electromechanical coupling capabilities. This abstract outline key thematic areas for in-depth discussion: Fundamentals of Piezoelectricity: Int [....] » Read More
The spontaneous interaction (emission or absorption) of a photon by atom is theoretically described in two-dimensional by a state vector |ψ⟩. As an initial solution to the problem, we derive its corresponding coherent state. We analytically find the fidelity between phot [....] » Read More
A new type of vacuum melting furnace for preparing multiple groups of element alloys has been developed, which has many functions of induction heating, casting heat treatment, electromagnetic separation, electromagnetic purification, electromagnetic stirring and mechanical mixing [....] » Read More
The increasing threat of antibiotic-resistant pathogens and the need for environmentally sustainable materials have accelerated research into biopolymer-based antimicrobial agents. This study addresses the question: Can natural polymers from agricultural and marine waste be engin [....] » Read More
This article analyzes the possibility of using the technology of plasma chemical deposition of films a-Si1-xGex:H (x=0÷1), unalloyed and doped PH3 and B2H6 in order to use them in p-i-n structures of solar cells. Optical properties were also determined, as well as the hydr [....] » Read More
Title : The effect of substitution of Mn by Pd on the structure and thermomagnetic properties of the Mn1−xPdxCoGe alloys (where x = 0.03, 0.05, 0.07 and 0.1)
Piotr Gebara, Politechnika Czestochowska, Poland
Refrigeration and temperature control involve a significant fraction of the electricity consumption nowadays. Energy efficient, environmental friendly procedures of thermal management will therefore have a direct impact on the sustainability of our way of life. Magnetocaloric ref [....] » Read More
Title : Application of vanadium and tantalum single-site zeolite catalysts in heterogeneous catalysis
Stanislaw Dzwigaj, Sorbonne University, France
The vanadium and tantalum ions well dispersed at zeolite framework are considered to be active sites of catalytic processes. Therefore, the incorporation of these metals into zeolites as isolated tetrahedral sites appears to be the important task. We have earlier shown that the i [....] » Read More
Title : Determination of phase stress flow curves in dual phase steels through micromechanical adaptive iteration algorithm
Silvie Maria Tanu Halim, McMaster University, Canada
Finite Element (FE) micromechanical modelling has significantly advanced the simulation of dual- phase (DP) steels by incorporating key microstructural features such as phase distribution and strain partitioning. A major ongoing challenge, however, is the accurate determination o [....] » Read More
Title : Fluorescent NH2-mil-88(Fe)-stabilized Ptnps nanozyme for dual-channel “off-on” simultaneous and visual detection of glyphosate and Pb2+ in agri-environments and foodstuffs
Huilin Li, Tianjin University of Science and Technology, China
Trace levels of pesticides and heavy metals in the environment and foodstuffs represent a substantial threat to human health. This study presented a bifunctional NH2-MIL-88(Fe)@Pt nanozyme possessing superior peroxidase-mimicking activity and fluorescence properties, further esta [....] » Read More
Title : Development the cost-effective water treatment materials to supply for flood, drought and saline intrusion areas in Vietnam
Tra Van Tung, Nguyen Tat Thanh University, Vietnam
Vietnam is significantly impacted by climate change, leading to flooding, drought, and salinity intrusion, which exacerbate clean water shortages. In rural areas of the Mekong Delta, existing water treatment systems meet only 61% of the clean water demand, resulting in the use of [....] » Read More
Title : The structure and properties of superplastic nickel-containing alloys
Liudmila Kveglis, East Kazakhstan University, Kazakhstan
Superplasticity is a unique property of materials that allows them to be deformed to extremely high degrees of stretching (up to 1000% and more) without failure. This phenomenon is actively studied in nickel-containing alloys due to their promising mechanical and functional chara [....] » Read More
Title : Failure analysis of 70cr2 steel grinding balls in mineral processing; Microstructural and heat treatment effects on the failure of 70cr2 steel grinding balls
