Synergistic Effects

Definition

Synergistic effects occur when the combined effect of two or more materials or processes is greater than the sum of their individual effects. This phenomenon is crucial in developing advanced materials, especially when designing composite materials and optimizing interfacial properties, as it can significantly enhance performance characteristics such as thermoelectric efficiency, mechanical strength, and thermal stability.
