Imaging at atomic resolution and elemental analysis at nanoscale has become essential characterization in advanced materials processing, development, and design. The range of experimental techniques available have been increasing and the researchers need to develop a high degree of expertise, both in the conduct of the analysis using these tools and interpretation of the acquired data/results. The lack of exposure and expertise in these techniques is becoming more and more a limitation in carrying out the high quality of research using these advanced research tools/techniques. This course aims to address this shortcoming.
The course will start with fundamentals of TEM and discussion of all the basic techniques and their typical applications. Both the theoretical aspects and practical applications will be discussed. Highlighting the advances in electron microscopy, it will also provide case studies of some challenging and precise analyses that is possible. The course is designed to cater both the aspiring as well as advanced researchers looking for an insight into the atomic/nano-/micro-scale details of materials. The objectives of the course are:
To give the basic understanding and an overview of advances in a range of techniques for nanostructures and nanoscale composition analysis.
With practical and demonstrations, provide firsthand feel for designing and carrying out experiments/ analysis on using these tools and techniques.
Data analysis and interpretation with a range of selected case studies.
The course will cover nano-characterization tools and Techniques viz. TEM, STEM/HAADF, HRTEM, electron tomography and nano-analysis with EDS, EELS. Major topics to be covered are:
1. Fill in google form and obtain approval to participate.
2. After approval fill in registration form and get signatures.
3. Send completed form along with the registration fee.
