Determination of Trace Metals in Individual Air Particulates Using Transmission Electron Microscopy
Ulrich, Sarah A. (2011-05)Ultramafic rocks, primarily serpentinite, in northern California contain high levels of Cr and Ni, both of which are known carcinogens. Due to weathering and land usage practices, these serpentenites are transported into ... -
Development of Techniques for Trace Metal Analysis Using Analytical Electron Microscopy
Lau, Todd R.; Ulrich, Sarah A. (2011-05)Analytical electron microscopy (AEM) using a transmission electron microscope (TEM) with an energy dispersive spectrometer (EDS) is usually considered a semi-quantitative analytical technique for major elements (>1 wt %). ... -
Penetrative Convection in Earth's Mantle : a Test Using Whole-Earth Geochemical Model.
Ulrich, Sarah A. (2009-07-23)The nature of mantle convection within the Earth remains one of the most important unanswered questions regarding Earth evolution. Two competing theories have been proposed; one backed primarily by geochemists invoking ... -
Rotational Periods of Asteroids 2167 Erin and 1084 Tamariwa.
Lorenzen, Kayla; Ulrich, Sarah A. (2009-02-03)We observed and analyzed asteroids 2167 Erin and 1084 Tamariwa to find their light curves and their rotational periods.
