Coming Around the Final Turn

Greetings once more from the ISC. Things in the lab have been moving forward, if rather slowly in some cases. We have been facing the inevitable issue of bottle-necking in terms of making use of the two magnets we have in our lab, for there are multiple projects which need to collect data. On top of that, we have recently discovered that the lift which allows us the vary the depths at which we are measuring during a single experiment has not been moving in accordance to the distances it is given in the software, which has slowed down all data collection as we work to correct or at ┬áleast better understand the issue. Nonetheless work progresses on the paint cleaning front. The samples which were assigned the isopropanol treatments have continued to be treated with the swab and gel techniques respectively. The double peak phenomenon exhibited by the sample which is swabbed with isopropanol could potentially be a result of isopropanol’s rapid evaporation rate, causing a peak to be observed where paint had swelled as normal, and another peak due to some isopropanol which has been trapped in the sample. The samples will continue to be treated on a regular basis and perhaps the next measurement will bring even more insight about the two peaks exhibited by the plain isopropanol.
