Yufei Meng works as a research scientist on the defects in different diamonds and their influence to properties and formation.

She is also interested in the relationship between diamond and mantle movements. Yufei's recent work has united spectroscopy with high-resolution microscopy to study the point defects and line/face defects and coloration mechanism in brown diamond. The applied spectroscopy methods include PL, FTIR, EPR and et al. The experiments obtained SR monochromatic X-ray diffraction high-resolution topographic images of diamonds for the first time in China. The results come to a closer look at the nature of the plastic deformation in brown diamonds.

Yufei received her Ph.D. from Sun Yat-sen University in China in 2006.

High Pressure
Washington, DC—In Earth’s interior, water (H2O) plays an important role in rock physics, but geoscientists rarely treat water in its constituent forms, that is as hydrogen plus oxygen. New work from a team led by the Geophysical Laboratory's Dave Mao has identified that hydrogen can escape from the water under conditions found in Earth’s lower mantle leading to a new paradigm in lower mantle chemistry. Their results were published in Proceeding of the National Academic Science, U.S.A.
