Question

Case No. 1
Situation:
A condensed matter experimentalist (Pl) and his students were conducting experiments
on thin films of common metals such as aluminium and tin. They realized that they coul
substantially enhance their work by switching the samples to the metal beryllium, which
is highly toxic and can bring about irreversible poisoning. The procedures that they are
employing with aluminium and tin would not be suitable for a toxic material such as
beryllium
Questions:
What responsibility does the PI have in considering the new, potentially dangerous
material for the research?
Case No. 2
Situation:
You are a graduate student working in a lab where data are accumulated for the
purposes of measuring the optical absorption of a variety of samples. For each sample
there is a large data file stored on a computer in the lab. In reviewing a lab notebook
from one of your predecessors in the lab and comparing that to data published by the
lab, you find a gap. That is, some of the data that were published are not accounted fc
in the lab notebook. Furthermore, you are unable to locate the computer files for this
missing data. You talk to a fellow graduate student about this situation, and he tells yo
that you should be very concerned about the situation and that it should be reported.
Questions:
What are some possible situations that could explain the missing" data, and how
should you proceed for each?​
