The Most Difficult Aspect of Your Research So Far

There were quite a couple of challenges because what I did was relatively new here in Taiwan. To find access to certain devices, to like Raman spectrometers, FTR spectrometers is always a bit challenging. And sometimes you also have getting trouble just like you want to take samples somewhere and it does not work because you can't access the area or access is denied completely. You're not allowed to do something there. So these are some you haven't felt any pushback from officials or or governments and you're collecting of data.
