Oriented graphitized layer
Witryna30 lis 2024 · Here, we report an efficient and controllable strategy to prepare highly oriented and ordered graphitized cellulose nanocrystal (GCNC) with well-defined sizes and shapes at low temperature and atmospheric pressure by hydrolyzing the disordered regions of microcrystalline cellulose with sulfuric acid and further dehydrating and … Witryna1 wrz 2024 · Graphitization is the process which improves lattice order with decrease in interlayer spacing in both graphitizing and non-graphitizing carbons. Some materials attain ordered orientation at 2000 °C (graphitizing), while others do not show homogeneous graphitic (ordered) structure even at 3000 °C (non-graphitizing).

Witryna17 lis 2011 · The carbon crystallites consist of graphene-layer stacks. A Hirsch analysis showed that the average graphene stack height increased with temperature up to ~2000 °C, reaching a relatively stable stack height thereafter. The average lateral layer size increased from 0.88 nm for the as-received fibers to 3.37 nm at 2500 °C. WitrynaThe electrospun carbon nanofibers with rich active sites, oriented graphitized layer, and intrinsic shape-adaptivity provide abundant access to uric acid molecules and enable efficient electron transmission.

Witryna1 kwi 1997 · The separation of the overgrown layer and the substrate crystals can be achieved by a near-surface graphitization of the substrate crystals due to implant- ation prior to overgrowth. Subsequent etching of this graphitized layer leads to a removal of the homoepitaxial layer from the substrate.
Witryna10 kwi 2024 · Hard carbons (HCs) have been emerging as promising anode materials for lithium-ion batteries because of their low redox potential and high reversible capacities. HCs consist of plentiful randomly oriented graphene nanosheets as described by the "house of cards" model.
