Contrary to earlier assumptions, the fibres spontaneously forming in aqueous colloids of detonation-produced nanodiamond (ND), do not consist purely of ND particles but are agglomerates of the latter with water and/or soft matter of biological (probably fungal) origin, as shown by elemental analysis, IR and Raman spectroscopy, X-ray diffraction, optical refractometry, optical and electron (TEM and ESEM)microscopy, as well as biological staining tests. © 2016.

Detonation-prepared nanocrystalline diamond powders usually contain hydrogen. Herein, the synthesis of practically hydrogen-free nanodiamond particles by detonation of benzotrifuroxan (BTF) and their comprehensive characterization by elemental analysis, X-ray diffraction, electron microscopy, DSC/TGA, and BTE specific-surface determination is described. The effects of the porosity of BTF and of various neutral or carbonic admixtures to the explosive on the reaction thermodynamics as well as the yield and properties of the product were explored theoretically and experimentally. Hydrogen contamination of nanodiamond was investigated using solid-state NMR spectroscopy and possible sources of hydrogen explored. Admixing hygroscopic solids to the explosive introduced 0.1 to 0.6% of hydrogen, as did purification in acidic (rather than neutral) media. © 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
