Boron monoxide archaeological dig (IMAGE) DOE/Ames National Laboratory Caption The structure of BO was a longstanding problem, dating back to 1940. Solving it required developing new NMR methods as well as applying x-ray diffraction (XRD), thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), x-ray photo electron spectroscopy (XPS), and transmission electron microscopy (TEM). This research is depicted here as an archeological dig.
