Web3 jan. 2024 · We observed that the HOPG substrate immediately allows an ACA of 73° with Li liq (Fig. 1 a). This is the first demonstration, to our knowledge, that graphite can be considered ‘lithiophilic’, which is encouraging from the view of fabricating Li-metal–matrix composite by Li liq infiltration. WebHOPG, or High Oriented Pyrolytic Grade, is an amorphous form of pyrolytic graphite that is produced by applying an additional tensile stress in the basal plane direction. This produces a more uniform, highly ordered structure and allows for the production of graphite with an interplanar spacing that is close to that of natural graphite.
WebIn this work, the self-assembly of a BODIPY dye, namely BODIPY-uracil, was deeply investigated on highly oriented pyrolytic graphite (HOPG) surface. BODIPY-uracil is a BODIPY derivative synthesized by Zhang et al. ( Zhang et al., 2024 ), as shown in Figure 1. WebHOPG crystals are widely used as substrates in STM (Scanning Tunneling Microscopy). The most distinguishing features of HOPG which enable this application are a very smooth surface and electro conductivity. HOPG has a layered structure which …
