First, a few words about William Wiley
Before we plow into the weekend s (and next week s) great art events, I would like to take a moment to remember first-generation UC Davis art faculty William Wiley. Some of my most fun and interesting days at the UC Davis campus were spent with Wiley. He came back to the university in 2014 to present his iconic Gong sculpture to campus. I wrote about that event here. Today, the San Francisco Chronicle published his obituary, which does a great job telling his life story from his days before UC Davis, at UC Davis, and after UC Davis. He was 83, passing away this week after battling Parkinson s disease. There will be more on Wiley later.
Analysis of Boron Isotope Ratio
Sponsored by PerkinElmerFeb 18 2021
Boron (B) is an element of interest in many scenarios, particularly for its isotope ratio composition in a range of geochemical, nuclear, paleoproxy, medical and archeological applications.
Boron offers two stable isotopes,
10B and
11B, the latter of which being four times more common. An earlier IUPAC report provided a fixed value (80.1%
11B) for the representative isotopic composition of boron,
1 however, the current edition of the report quotes a natural abundance range of 79.6 – 81.1%
11B.

For purely practical purposes, the earlier presented value is reserved for situations where isotope composition is unknown.
Boron isotope ratios found in nature can vary by around 100‰ (parts per thousand, or permil) or 10%
