When a theory was thoroughly clarified in a report to the point that it warranted applause, a Q&A session wouldn't be necessary.
Of course, there were still many people that asked questions during the Q&A session.
Lu Zhou answered all of the questions in detail.
This was undoubtedly more exciting than the MRS Conference which didn't have a single question.
This meant that the audience was actually paying attention.
After the report, several doctoral holders from Humboldt University went on stage and asked for Lu Zhou's signature. They said it was to commemorate this chemistry historic moment.
Although Lu Zhou didn't think that history would remember such trivial matters, he still fulfilled their request and scribbled his signature on their textbooks.
