Logbook STM Main Page
= = =November 2007=


 * || ===Week of Nov 5 to Nov 9=== ||
 * Monday 5 || look at other classmates journals/ logbooks and make fruitful comments as well as compare and contrast with mine to make improvements and see variety. ||
 * Tuesday 6 || I put together AR's images into a ppt; I still have to upload it tomorrow at school. I also finished looking at my classmates journals. ||
 * Wednesday 7 || double check my classmates journals. And I went to Notre Dame to see STM and STM with a vaccum intergrated. The only difference is that STM with the vaccum was meant to shot Hydrogen ions to a sample and observe the damage of the sample after several intervals. But overall it ahs the same functions of an STM. ||
 * Thursday 8 || (half day/career day) ||
 * Friday 9 || no school ||


 * || ===Week of Nov 12 to Nov 16=== ||
 * Monday 12 || started working on posting notes ||
 * Tuesday 13 || research on octanethiol, alkanethiols and benzene ||
 * Wednesday 14 || looked into the Z range in a piezo tube and how it can crash and affect your image. ||
 * Thursday 15 || I went to Quark Net. A and me refreshed on how to work the portable STM and the shape that octhanthiol forms compare with Gold's shape. We got a great image eventhough we had a double tip. This time I knew what was going on. I also learned that you want to have your tip scan at a medium speed: not to fast because it will make your tip crash since the tip would not have time enough to react top peaks; but not to slow because it might give you an inaccurate image since it takes longer to figure that the tip is not getting enough current( it takes longer to detect). So you want to have a tip that detects and reacts on time. ||
 * Friday 16 || go over A's ppt and explain octhanethiol. ||


 * || ===Week of Nov 19 to 23=== ||
 * Monday 19 || posted a brief explanation on octanethiol ||
 * Tuesday 20 || continued my research and try to add helpful links ||
 * Wednesday 21 || Linked visual aids of the STM project page ||
 * Thursday 22 || Happy Thanksgiving ) ||
 * Friday 23 || n/a ||

//I went to the ND project fair where I answer questions to teachers and explain the basics of STM and how it works as well as try to run it. But the tip was so small and there was to much noise so I could not scan. I ran the softwares sample but I did not like it. I ended up showing images obatined before; specially the one nice image AR and me got when we had a double tip//. || «Previous month Next Month»
 * || ===Week of Nov 26 to Nov 30=== ||
 * Monday 26 || e-mail AR on next meeting, try to download the Version 4.6.0, released 2007-11-21 of the new SPIP VERSION ||
 * Tuesday 27 || download SPIP new version ||
 * Wednesday 28 || I am going to the Quark Net. I am so excited because I get to try the STM myself ! I am back from the lab. I did try setting up all by mysef; and I must say it was harder than what I believed it was going to be. I had to cut my tip of the fine tungsten wire and it felt in the floor twice. Then when I tried to set the tip it went inward. So after trying half an hour to get the tip ready to scan, I had to get my sample ready. That was easy but the clip would get on the tips scan and we don not desire that. So trying to find a good angle to place the sample and the angle took a while. Finally I was ready to approach my sample as close to my sample. But I ended up crashing my tip and running out of time to redo everything and actuallly scan. ||
 * Thursday 29 || Senior Retreat ||
 * Friday 30 || no school
