How this entity was disambiguated
This entity first appeared as the object of triple T13031892 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

B.
Kikuchi lines in electron diffraction
Kikuchi lines in electron diffraction are characteristic pairs of diffuse, intersecting bands in electron diffraction patterns that arise from inelastic and subsequent coherent scattering in crystals, and are widely used for precise crystallographic orientation analysis.
-
C.
X-ray microscopy
X-ray microscopy is an imaging technique that uses X-rays instead of visible light to produce high-resolution images of the internal structure of materials and biological specimens at the nanoscale.
-
D.
scanning tunneling microscope
A scanning tunneling microscope is a powerful instrument that images surfaces at the atomic scale by measuring quantum tunneling currents between a sharp conductive tip and a sample.
-
E.
Zernike phase-contrast method
The Zernike phase-contrast method is a microscopy technique that converts phase shifts in light passing through transparent specimens into intensity differences, enabling detailed visualization of living cells and other unstained samples.
- F. None of above. chosen

The pipeline generated the facts above by prompting gpt-5.1 with this entity's name + description and the instruction below.
Instruction
You are a knowledge base construction expert. Given a subject entity and a description of it, return factual statements that you know for the subject as a JSON list of dictionaries(triples), where keys must be "subject", "predicate" and "object". The number of facts may be very high, between 25 to 50 or more, for very popular subjects. For less popular subjects, the number of facts can be very low, like 5 or 10. # Requirements - If you don't know the subject at all, return an empty list. - If the subject is not a named entity, return an empty list. - Include at least one triple where predicate is "instanceOf". - Do not get too wordy. - Separate several objects into multiple triples with one object.
