Charge storage in mesoscopic graphitic islands fabricated using AFM bias lithography [PDF]

open access: yes, 2011
Electrochemical oxidation and etching of highly oriented pyrolytic graphite (HOPG) has been achieved using biased atomic force microscopy (AFM) lithography, allowing patterns of varying complexity to be written into the top layers of HOPG.

Impact of Hydrogen Peroxide on Carbon Corrosion in Aqueous KOH Solution

open access: yesElectrochemistry, 2022
Impact of hydrogen peroxide on carbon corrosion is investigated by immersion tests of catalyst-deposited highly oriented pyrolytic graphite (HOPG) samples to an aqueous solution of 1.0 mol dm−3 KOH + 5 mmol dm−3 H2O2. The surfaces of the HOPG samples are

Magneto-electrical orientation of lipid-coated graphitic micro-particles in solution† [PDF]

open access: yesRSC Advances, 2016
We demonstrate, for the first time, confinement of the orientation of micron-sized graphitic flakes to a well-defined plane. We orient and rotationally trap lipid-coated highly ordered pyrolytic graphite (HOPG) micro-flakes in aqueous solution using a ...

Analytical potential of EDXRF using toroidal focusing systems of highly oriented pyrolytic graphite (HOPG) [PDF]

open access: yesX-Ray Spectrometry, 2002
Abstract To solve a number of geochemical problems for ultrabasic and basic rocks, we applied the simplest and most accessible EDXRF method on an x‐ray tube with the use of toroidal double concave focusing systems and highly oriented pyrolytic graphite (HOPG). The results of measurements on clinopyroxene grains are shown.

Hydrogenation of HOPG-supported Gold Nanoparticles: Features of Initial Stages

open access: yesCrystals, 2019
The features of deuterium adsorption on the surface of gold nanoparticles deposited on highly oriented pyrolytic graphite (HOPG) were determined. The results showed that deuterium adsorption on gold nanoparticles takes place at room temperature.
