WebThe increase of impurity levels compared to pristine C60 powder (~22 µg/g) is likely due to contamination introduced during the HPHT synthesis. One of the samples (No. 4) of graphite-like carbon (synthesized at 3.5 GPa, 1085 K and 1000 sec annealing time) was studied by PIXE in 5 different regions of ~0.8 mm diameter. Web1 dec. 1994 · The chemical inertness and corrosion resistance of a boron‐doped diamond thin film electrode, grown by chemical vapor deposition (CVD), have been studied during …
WebIn the case of carbon based catalysts that difficulty is compounded by the variability of the carbon powders used. We have previously developed a strategy that addresses these problems by mimicking the catalyst preparation conditions very closely but using highly ordered pyrolytic graphite crystals (HOPG) as a model surface. This enables us to
