Rhombohedral stacking-faults in exfoliated highly oriented pyrolytic graphite

Carbon Trends
The recent observation of possible granular superconductivity in highly oriented pyrolytic graphite (HOPG) has attracted significant research interest. Here we report a novel investigation on the structural-properties of exfoliated-HOPG.

Electrochemistry at highly oriented pyrolytic graphite (HOPG) : toward a new perspective

, 2015
This chapter is concerned with electrochemistry at, and of, highly oriented pyrolytic graphite (HOPG), a material that has been studied intermittently for several decades, but which is of enduring interest particularly as a comparison to other types of ...

Coordination Chemistry of Boron Subphthalocyanine With BINOL Derivatives: Unexpected Oxidation to Oxa[4]Helicene and Properties of the Resulting Axially Coordinated Complexes Containing Oxa[4]Helicene and/or BINOL Derivatives

Chemistry – A European Journal, Volume 32, Issue 40, 27 October 2026.
Treatment of BINOL with a boron subphthalocyanine derivative resulted in the formation of a complex coordinated to an oxa[4]helicene derivative, which is generated via a ring‐closure reaction of BINOL. In contrast, treatment of the monomethyl ether of 1,1′‐bi‐2‐naphthol (BINOL) afforded the expected axially coordinated complex.

Adsorption of a Laccase from Fusarium Proliferatum on Au (111) and HOPG Electrodes: a Scanning Probe Microscopy and Electrochemical Approach

International Journal of Electrochemical Science, 2012
A laccase enzyme produced by Fusarium proliferatum was successfully adsorbed as a laccase submonolayer (SML) on a bare Au (111) single-crystal electrode (Au), the same electrode modified with a hexadecanethiol self-assembled monolayer (SAM-Au) then ...
