Thank goodness they are back to the high power levels.
As I noted in my presentation in India, Mizuno provided the cell and did most of the material preparation in the first round of experiments. That does not mean the results are suspect, but it does mean the know-how may not have been transferred. I hope Muto did most of the work this time around. I don't know what the situation is. I have not heard from them since I sent a draft of the presentation a few weeks before I gave it.
One of Muto"s grad students. Don't know if Mizuno helped him. Hopefully we will be authorized to pass on more details.
