Sažetak	Selected Area Electron Diffraction (SAED) is a crystallographic technique in transmission electron microscopy that obtains electron diffraction patterns from micron-sized or sub-micron crystalline regions. Developed from fundamental principles of electron wave behavior and integrated into TEM instruments by the mid-20th century, SAED enables direct observation of reciprocal space, crystal symmetry, and defect structures with spatial resolution unattainable by X-ray diffraction. It is essential for studying local crystal structure, phase identification, and characterizing nanoscale materials.	Energy-Dispersive X-ray Spectroscopy (EDS) is an analytical technique that identifies and quantifies chemical elements in microvolumes of samples by analyzing characteristic X-rays emitted during electron bombardment. Rooted in Moseley's discovery of characteristic X-ray lines in 1913 and developed as a practical microanalytical tool by the 1970s, EDS is integrated into scanning electron microscopes (SEM) and transmission electron microscopes (TEM) for spatially-resolved elemental analysis. It is indispensable in materials characterization for phase identification, compositional mapping, and alloy development.
