Electrogenerated Chemiluminescence of Partially Oxidized Highly Oriented Pyrolytic Graphite Surfaces and of Graphene Oxide Nanoparticles

, 2009
Electrogenerated chemiluminescence (ECL) can be obtained from an etectrochemically oxidized highly oriented pyrolytic graphite electrode or a graphene oxide suspension in an aqueous solution containing 0.1 M NaClO4, phosphate buffer (PBS) (pH = 7.0) and ...

Oxidative etching of Ta-cluster-ion-bombarded highly-oriented pyrolytic graphite

, 1997
Bombardment of highly-oriented pyrolytic graphite by energetic monomer and cluster ions (555 eV/atom Ta-1(+), Ta-2(+), Ta-4(+) or Ta-9(+)) is used to introduce surface defects which, after baking in air at approximate to 630 degrees C, nucleate ...

Solubilized Derivatives of Perylenetetracarboxylic Dianhydride (PTCDA) Adsorbed on Highly Oriented Pyrolytic Graphite

, 2016
The effect on 2D molecular crystallization caused by the addition of propylthioether side groups to the 3,4,9,10-perylenetetracarboxylic dianhydride (PTCDA) molecule is investigated using scanning tunneling microscopy (STM).

The effect of structural disorder on the secondary electron emission of graphite

AIP Advances, 2016
The dependance of the secondary electron yield (SEY) on the degree of crystallinity of graphite has been investigated during the amorphization of a highly oriented pyrolytic graphite (HOPG) samples by means of Ar+ bombardment.

Self-assembled polyphenylene dendrimer nanofibers on highly oriented pyrolytic graphite studied by atomic force microscopy

, 2002
Self-assembled nanostructures of various polyphenylene dendrimers, prepared by drop casting dendrimer solutions on the surface of highly oriented pyrolytic graphite (HOPG), have been investigated by noncontact atomic force microscopy (NCAFM).

Calcium carbonate crystallisation at charged graphite surfaces

, 2017
For identical solution conditions, the crystallisation of calcium carbonate (polymorph and crystal orientation) at Highly Oriented Pyrolytic Graphite substrates is highly dependent on substrate surface charge.

Infrared probe of the anomalous magnetotransport of highly oriented pyrolytic graphite in the extreme quantum limit [PDF]

, 2006
We present a systematic investigation of the magnetoreflectance R(omega,B) of highly oriented pyrolytic graphite in magnetic field B up to 18 T. From these measurements, we report the determination of lifetimes tau associated with the lowest ...

Low-energy electron diffraction study of potassium adsorbed on single-crystal graphite and highly oriented pyrolytic graphite [PDF]

Potassium adsorption on graphite has been a model system for the understanding of the interaction of alkali metals with surfaces. The geometries of the s232d structure of potassium on both single-crystal graphite (SCG) and highly oriented pyrolytic ...

Synthesis and properties of mirror-like large-grain graphite films

Nature Communications
Graphite films with large grain sizes have been reportedly obtained by using metal as catalysts, but the obtained graphite is mostly heavily wrinkled, thus containing defects that degrade its properties.

A comparative characterisation of Highly Oriented Pyrolytic Graphite by means of diffraction topography

, 1999
The Highly Oriented Pyrolytic Graphite was examined to study the crystal internal structure and correlate it with the crystal optical behavior. Different samples were studied using x-ray diffraction topography.
