KernHülleModell
The KernHülleModell, often translated as the "core-shell model," is a concept used in various scientific disciplines to describe structures with a distinct central component surrounded by an outer layer. This model is particularly prevalent in materials science and chemistry. In essence, it posits a two-part system where the inner core possesses different properties than the outer shell. These properties can vary widely, encompassing chemical composition, physical state, optical characteristics, or electrical conductivity.
The formation of core-shell structures can occur through various synthesis methods, such as chemical precipitation, vapor
