Dear researchers, I am a professor of chemistry and a researcher in the field of functional materials, with a particular focus on dielectric materials for microwave resonators and electronic applications. My research involves the synthesis and characterization of complex materials such as A₂LnTi₂Nb₃O₁₅ (where A is an alkali metal and Ln is a rare earth element), tungsten bronze-type ceramics, perovskite structures such as CaCu₃Ti₄O₁₂ (CCTO), and various composites. I specialize in the structural (XRD) and electrical (impedance spectroscopy, AC conductivity) analysis of materials, with a strong interest in dielectric properties, non-Debye relaxation behavior, temperature-dependent electrical responses, and materials exhibiting NTCR characteristics. I also have practical experience with crystallographic refinement software such as Jana2006. I have contributed to several research projects, published in peer-reviewed international journals, and participated in manuscript evaluations. I believe that my scientific experience and commitment would be valuable in ensuring the quality and relevance of the selected papers for this issue. Best regards.
