Full Description
The International Symposium on Dielectric Materials and Applications (ISyDMA) conference series provides a distinguished global platform for researchers and scientists to exchange ideas, present findings, and engage in in-depth discussions on recent advances in dielectric materials and their emerging applications. The ISyDMA Proceedings volumes serve as comprehensive records of cutting-edge research on topics including high-κ dielectrics, electrical insulation, dielectric phenomena, and novel applications spanning biomedical technologies, energy harvesting, materials for critical infrastructure, and smart materials. The ninth edition of ISyDMA (ISyDMA'9) was hosted by Cadi Ayyad University, Marrakesh, Morocco, from May 7-9, 2025. This proceedings volume compiles the peer-reviewed papers presented at the conference. It opens with keynote contributions that offer overarching perspectives on mechanisms, processes, and applications of dielectric materials, followed by original research articles from participating scholars. Among the notable contributions, one study investigates how the structural self-organization of chalcogenide glasses influences low-frequency Raman scattering (Boson peaks), providing insights into the underlying mechanisms. Another article examines the impact of compositional variations and processing parameters on the optical characteristics of nonstoichiometric glassy films. Research on the parametric optimization of dielectric materials for energy harvesting in IoT devices demonstrates how systematic modeling can significantly reduce experimental trial-and-error in materials fabrication by identifying optimal process parameters. A study on microplasma-sprayed hydroxyapatite coatings illustrates enhanced surface bioactivity in 3D-printed titanium implants, underscoring their clinical promise for biomedical applications. Addressing environmental challenges, another contribution explores the use of dielectric barrier discharge as an innovative technique to mitigate microplastics in aquatic systems. Further, an article describes a photoacoustic method for evaluating the optical absorption coefficients of nanostructured silicon with varying morphologies, along with a comparative study of DC electrical conductivity in 2D and 3D polypyrrole particles embedded in different polymer matrices. Investigations into the synthesis, structural analysis, and dielectric properties of high-purity NiMoO₄ nanospheres with monoclinic symmetry reveal their potential for advanced electronic applications. A theoretical paper on the spectroscopy and electronic structure of group-12 metal carbides and nitrides provides critical insights to guide future experimental and computational studies of transition-metal-based diatomic materials. Several contributions highlight that moderate doping can significantly enhance the electrochemical performance of dielectric materials, demonstrating their suitability for next-generation energy storage systems. An interesting work discusses Poly(vinylidene fluoride) membranes fabricated via non-solvent-induced phase separation and modified with styrene-butadiene rubber and graphene nanosheets. The resulting β-phase-rich, polarizable structures exhibit tunable electronic conductivity, making them attractive for piezoelectric energy harvesting applications. Additional articles address the integration of AI in energy management and consumption optimization, as well as applications such as high-efficiency photodetectors based on optically transparent and dielectric materials for monitoring hazardous substances in mail distribution systems. The volume also includes several student contributions highlighting innovative aspects of dielectric science and its interdisciplinary applications. The unique collection of articles is intended for materials scientists, physicists, chemists, biologists, and electrical engineers engaged in fundamental and applied research or technical investigations involving dielectric materials and related technologies.
