Course Coordinator: Dr. Hemalatha

Introduction: Introduction of different characterization techniques and its importance, structure-property correlation, characterization of materials at different levels (macro, meso, micro and nano).

Structure analysis tools: X-rays, characteristic X-ray spectrum, Bragg’s Law, Diffraction methods, Principle, equipment and applications, structure factor, Bravais lattice, filters and counters/detectors, applications of X-ray diffraction in materials characterization – determination of crystal structure, lattice parameter and porous structure; Optical characterization techniques: Optical microscopy – principle of working, importance and applications, sample preparation, theoretical and practical resolution, numerical aperture, principle of image formation, effective/empty magnification, Advanced Microscopic Techniques, Absorption, transmission, reflection, Different sophisticated spectroscopy methods; Thermal analysis techniques:Differential thermal analysis – principle of working, accuracy, sensitivity, calibration, importance, and applications, Differential Scanning Calorimetry; Applications: Applications of different characterization techniques for crystalline, non-crystalline materials and amorphous materials with due emphasis on cement based materials
