👉 Sigma engineering is a methodology used in chemical and materials science to systematically optimize the properties of materials by controlling the composition and microstructure at the atomic level. This approach involves the strategic manipulation of elemental ratios, dopants, and defects to enhance specific properties such as conductivity, strength, or catalytic activity. By understanding and controlling these factors, researchers can design materials with tailored functionalities for various applications, from electronics to energy storage. Sigma engineering leverages advanced computational models and experimental techniques to predict and achieve optimal material performance, making it a powerful tool for innovation in materials science.
