Article: Reports summarize ceramics study results from University of Central Florida.(Report)

"Nanosized carbon clusters self-formed in polymer-derived ceramics (named free carbon) play a key role in determining the properties of the materials. However, it is difficult to quantitatively measure the concentration of the free carbon," researchers in the United States report.

"Lack of this information restricts the understanding of the properties of the materials. In this paper, we report a Raman spectroscopy-based quantitative method to measure the free carbon concentration by using silicon as an external reference," wrote T. Jiang and colleagues, University of Central Florida.

The researchers concluded: "We demonstrate that the technique provides ...
