Adsorption of dicyanoaurate (I) ions on highly oriented pyrolytic graphite

, 1998
The adsorption of dicyanoaurate (I) onto the surface of activated carbon is the basis of modern techniques for gold extraction. The process is very efficient and has been the major factor in improving the productivity of the gold mining industry over the

Nanopatterns of arylene–alkynylene squares on graphite: self-sorting and intercalation

Beilstein Journal of Organic Chemistry, 2019
Supramolecular nanopatterns of arylene–alkynylene squares with side chains of different lengths are investigated by scanning tunneling microscopy at the solid/liquid interface of highly oriented pyrolytic graphite and 1,2,4-trichlorobenzene. Self-sorting

C-Axis Thermoelectric Power of Highly Oriented Pyrolytic Graphite

Journal of the Physical Society of Japan, 1993
Thermoelectric power in c -direction ( S c ) of highly oriented pyrolytic graphite (HOPG) exhibits a sharp negative dip around 20–30 K. This anomaly is ascribed to the phonon drag thermoelectric power ( S p ) related to the out-of-plane vibration and S p is calculated in close relation to the mechanism of c -axis conduction.

Apparent corrugation variations on moiré patterns on highly oriented pyrolytic graphite

Materials Today Communications, 2016
Abstract Many different moire patterns were reported on highly oriented pyrolytic graphite (HOPG) surfaces in scanning tunneling microscopy (STM) studies. Such observations were attributed to the dislocation of the top most graphene layers of the crystal with respect to the lower layers.

Mono- and multilayers of molecular spoked carbazole wheels on graphite

Beilstein Journal of Organic Chemistry, 2014
Self-assembled monolayers of a molecular spoked wheel (a shape-persistent macrocycle with an intraannular spoke/hub system) and its synthetic precursor are investigated by scanning tunneling microscopy (STM) at the liquid/solid interface of 1-octanoic ...

Scanning Tunneling Microscopy and Atomic Force Microscopy of Au Implanted in Highly Oriented Pyrolytic Graphite

, 1995
Surfaces of highly oriented pyrolytic graphite implanted with gold were studied by both constant current STM. constant force, and tapping mode AFM. Gold colloids were observed by both constant current STM and tapping mode AFM.
