After two weeks experimentation on EPMA olivine minor and trace element analyses. Now the technique has been established! We are able to measure trace elements in olivine below 50ppm with sufficient data accuracy. Cheers!
After weeks preparation and a 2-hour long Oral Qualifying Exam, I passed my Oral Quals! I am now an official UF PhD candidate. Cheers!
Keep on working! After a long week wait, I got message from committee chair that I passed my PhD written Quals!
The written qualifying exam is done in one week, during which you need to write a 4-5 page literature review or discussion article to answer the committee members questions. References and necessary figures and/or tables are required. The writing should be done within eight hours, one day per question. Cheers! Getting closer to a PhD candidate! My oral presentation was successful! Super excited to share my new findings and discuss with colleagues. Looking forward to next year's meeting!
It was really exciting to attend this "tiny" but professional conference, with only ~100 attendee. The QMA stands for Quantitative MicroAnalysis. This conference (the-mas.org/events/topical-conferences/qma-2019/) was organized by the Microanalysis Society (MAS), hosted by University of Minnesota, taking place on June 24-27, 2019. One of my figures in my submitted abstract was luckily selected as the cover of the program. Check this out! the-mas.org/wp-content/uploads/2019/06/QMA-2019-Program-final-1.1-HQ.pdf I was awarded the MAS Early Career Scholar in this conference! And my travel cost was almost fully covered by the award I received. This conference has so many world-class microanalysis (EPMA, SEM, etc.) professors from USA, England, France, Germany, Australia, they gave awesome talks and I got a chance to talk to them (Michael Jercinovic, Julien Allaz, John Fournelle, Paul Carpenter, etc.) in person. (Group photo of the Early Career Scholar. Too bad that I was not looking at the camera when the photo was taken!)
After a few trials, I successfully applied our improved background modeling on the Pb and U analyses. The detailed WDS step scans of Pb Mα and U Mβ were S-G (Savitzky–Golay) filtered and "range-based" modeled. The data accuracy now have been significantly improved! Keep on working! |
