From: Nanostructured carbon-based membranes: nitrogen doping effects on reverse osmosis performance
(a) TEM micrographs for the sputtered NC-based membrane samples using different gas mixtures. (b) EELS spectra in the carbon K-edge region, for the studied carbon membranes. The dotted vertical lines depict the energy loss for 1s to π* and 1s to σ* peaks. (c) Calculated (sp3)(100)/(sp2+sp3) ratios from EELS π* and σ* peaks.
