Hi Alex, this is pretty interesting! I cant access the website, it is probably unavailable now, but the stream is clear! Do You have any graph how the absorbance rise during that those 7000 minutes?
Are You running it on specs current or on higher to make the process faster? The sputtering is not directly proportional to current, so it would be nice to have data for currents from datasheet.. Thanks!
