Things to consider as starting points:
What is the theoretical basis for the characterization technique, synthetic method and/or general theme?
What are the nuts and bolts of the method, e.g. for a characterization technique samples size, geometry, sample prep, etc?
What is the current state of the art regarding this topic?
For instruments: Who are the leading manufacturers in the field and what is the typical cost of the instrument?
For other topics: Who are the leading researchers in the field?
What are the limitations associated with the topic? Is there room for improvement?
