This review investigates the processing‐microstructure‐property relationships in ferritic stainless steels (FSSs). It highlights advances in deformation behavior, heat treatments, surface modifications, and alloying effects. Theoretical models, including Johnson‐Mehl‐Avrami‐Kolmogorov, Arrhenius, nucleation theory, and diffusion theories, are discussed

Modulation excitation spectroscopy (MES) is a powerful method to provide information on active species and sites in catalytic reactions. We present the design of a diffuse‐reflectance IR Fourier transform spectroscopy (DRIFTS) cell, which is suitable for MES but also applicable to other in situ and operando DRIFTS studies on catalytic materials.
