For a 15-slide MSc Chemistry presentation, I’d structure it like this: 15-slide structure: Surface Characterization Techniques 1. Title Slide Surface Characterization Techniques SEM, TEM and other important techniques 2. Introduction to Surface Characterization What is surface characterization? Why surface properties matter Applications in materials chemistry, nanotechnology, catalysis, corrosion, etc. 3. Properties Characterized Surface morphology Topography Surface composition Elemental composition Crystal structure Chemical states Surface area and porosity 4. Classification of Techniques Microscopic techniques Spectroscopic techniques Diffraction techniques Surface-area/porosity techniques 5. SEM — Scanning Electron Microscopy Principle Instrumentation Image formation Applications 6. TEM — Transmission Electron Microscopy Principle Instrumentation Image formation Applications 7. SEM vs TEM Surface vs internal structure Sample requirements Resolution Information obtained 8. AFM — Atomic Force Microscopy Principle Cantilever and tip Surface topography Advantages and applications 9. STM — Scanning Tunneling Microscopy Tunneling principle Conductive surfaces Atomic-scale imaging Applications 10. XPS — X-ray Photoelectron Spectroscopy Principle Surface elemental composition Oxidation states/chemical states Applications 11. EDS/EDX — Energy Dispersive X-ray Spectroscopy Principle Characteristic X-rays Elemental identification SEM-EDS combination 12. XRD — X-ray Diffraction Bragg's law Crystal structure Phase identification Crystallite size 13. BET Surface Area & Porosity Analysis Adsorption–desorption Specific surface area Pore size and pore volume Importance for catalysts and nanomaterials 14. Comparison of Techniques A table comparing: SEM TEM AFM STM XPS EDS XRD BET Compare what they measure, sample requirements, resolution, and major applications. 15. Conclusion + References No single technique provides all surface information. Techniques are often combined for complete characterization. Add 5–8 good textbook/review references. The important point If your seminar title is specifically “Surface Characterization Techniques”, I would not spend 10–12 slides just on SEM and TEM. A good MSc-level presentation should show how different techniques provide complementary information. A particularly good flow is: Surface → Morphology → Structure → Composition → Chemical state → Surface area/porosity with SEM + TEM + AFM + XPS + EDS + XRD + BET as the main techniques.
