Monoclinic s...

Due to the rising demand for composite materials that integrate the advantages of both components, material science has increased in both popularity and utilization. Over the past few years, there has been an increase in interest in modifying the structural characteristics of materials on a nanometre scale. The fundamentals of polymers are delibera...

In this chapter, composites are macroscopic-scale materials created by the fusion of two or more materials with various chemical, physical, and morphological components. These materials acquire certain brand-new or enhanced mechanical, chemical, physical, and other properties that are unrelated to those of their constituent parts. To meet some uniq...

The paper presents a synthesis (solid-state. reaction) and characterization of a lead-free double perovskite oxide Ba 2 (FeMo)O 6 ceramic.
