Abstract

Centrifugal casting offers unique advantages, combining large centrifugal forces with directional solidification to minimize non-metallic inclusions in steel. This study investigates how calcium wire ladle treatment modifies and reduces these inclusions to improve machinability and mechanical performance. Using samples collected at various stages of treatment and final casting, inclusion analysis and mechanical testing were conducted. Results highlight that calcium addition after argon oxygen decarburization (AOD) is optimal for inclusion modification. However, centrifugal forces played a more dominant role in inclusion distribution, demonstrating the complementary effects of these processes. The findings indicate that a combination of chemical and mechanical treatments can significantly enhance steel cleanliness and mechanical reliability. Furthermore, recommendations are made for optimizing process parameters to achieve consistent production of high-quality steel.

Abstract

The increasing demand for aesthetic, durable, and high-performance composite materials has led to significant advancements in In-Mold Decoration (IMD) techniques. This study investigates the integration of thermoformable polycarbonate paint films with the Resin Infusion between Double Flexible Tooling (RIDFT) process to enhance surface quality, durability, and production efficiency. A combination of computational modeling, experimental validation, and process optimization is applied to improve resin adhesion, thermal stability, and environmental sustainability. Key advancements include the implementation of convection heating, enhanced vacuum infusion systems, and machine learning-based process control. Experimental results demonstrate a 30% reduction in surface defects, a 25% improvement in mechanical performance, and an 85% reduction in VOC emissions compared to conventional post- mold finishing. This study establishes a scalable and sustainable pathway for next-generation composite manufacturing.

Abstract

Water exhibits fascinating structural and electronic properties, with significant implications for condensed matter physics. This study explores the hydrogen bond network in ice XIII and the structural transitions in hydrogen hydrate under pressure using first-principles methods. Oxygen K-edge X-ray absorption spectroscopy (XAS) investigates the local structure of ice phases, revealing strong sensitivity to hydrogen bonding. First-principles molecular dynamics (FPMD) simulations demonstrate pressure-induced phase transitions in hydrogen hydrate. These findings contribute to understanding hydrogen bonding and phase transitions in water-related systems, with potential applications in planetary science and hydrogen storage.

Abstract

Blue pigment (BaCuSi4O10) has been a historically significant material used in art, ceramics, and optics. Recent advancements in nanotechnology have enabled scientists to synthesize nanoscale blue pigment with enhanced properties, expanding its applications in biomedical imaging, photothermal conversion, and optoelectronic devices. This study reviews the historical context, developments in synthesis techniques, and novel applications of nanoscale blue. Methodologies such as hydrothermal synthesis, sol-gel methods, and microwave-assisted fabrication are discussed. Furthermore, its nanotechnological applications, including optical materials, biomedical tagging, and high- performance pigments, are explored. Future research should focus on improving its environmental stability, biocompatibility, and integration with modern nanocomposites.
