Graphite monochromator
http://pd.chem.ucl.ac.uk/pdnn/inst1/monoc.htm WebThe operation power of the X-ray generator was 18 kW, CuKα irradiation (λ = 1.54056 Å) was applied, the pressure and the current were 40 kV and 200 mA, respectively. Under filtering by a graphite monochromator with high reflection efficiency, scanning was conducted with a scanning rate of 4°/min from 10–90°.

WebThe dispersion of platinum (Pt) on metal oxide supports is important for catalytic and gas sensing applications. In this work, we used mechanochemical dispersion and compatible Fe(II) acetate, Sn(II) acetate and Pt(II) acetylacetonate powders to better disperse Pt in Fe2O3 and SnO2. The dispersion of platinum in SnO2 is significantly different from the … WebORIENTED GRAPHITE AS A NEUTRON MONOCHROMATOR T. RISTE and K.
