 We thank K. Knight for providing the detonation ND. This work is supported by grants from NASA to PRH and AMD and from the Tawani Foundation and W. H. Ganz III to PRH. Atomic layer deposition was performed at Argonne National Laboratory (ANL). Some UNCD film growth was performed at the Center for Nanoscale Materials at ANL, which is supported by the U.S. Department of Energy, Office of Science, Office of Basic Energy Sciences. Some UNCD film growth and some of the FIB work performed at the ANL was supported by the US Department of Energy, Materials Sciences and Engineering Division. This FIB work was accomplished at the Electron Microscopy Center at ANL, a U.S. Department of Energy Office of Science Laboratory operated by UChicago Argonne, LLC. The LEAP tomograph at NUCAPT was purchased and upgraded with funding from NSF-MRI and ONR-DURIP. This research made use of the Shared Facilities at the Materials Research Center of Northwestern University (NU), supported by the NSF’s MRSEC program. The Initiative for Sustainability and Energy at Northwestern (ISEN) is acknowledged for grants for upgrades at NUCAPT. Some of the FIB work was performed at the NUANCE Center at NU. NUANCE is supported by NSF-NSEC, NSF-MRSEC, Keck Foundation, the State of Illinois, and NU.
