Electrodeposition of Two-Dimensional Pt Nanostructures on Highly Oriented Pyrolytic Graphite (HOPG): The Effect of Evolved Hydrogen and Chloride Ions [PDF]

Nanomaterials, 2018
We discuss the electrodeposition of two-dimensional (2D) Pt-nanostructures on Highly Oriented Pyrolytic Graphite (HOPG) achieved under constant applied potential versus a Pt counter electrode (Eappl = ca. −2.2 V vs. NHE, normal hydrogen electrode).

Microcracks in Nuclear Graphite and Highly Oriented Pyrolytic Graphite (HOPG)

Journal of Nuclear Materials, 2008
Microcracks with varied length and width are observed in nuclear grade graphite and highly oriented pyrolytic graphite (HOPG) by transmission electron microscopy. In situ observations show that these cracks tend to close up on heating the sample. The crystal dimensional change from in situ electron-irradiation also causes the closure of the cracks ...

Recent studies of highly oriented pyrolytic graphite and hybrid graphite-silicon monochromator systems [PDF]

EPJ Web of Conferences, 2023
The excellent performance of highly oriented pyrolytic graphite (HOPG) as monochromator, analyzer and filter material for neutron instrumentation was discovered more than 50 years ago. Even though HOPG has been in use for a long time, there is still room

Kinetics of Interfacial Lithium-ion Transfer between a Graphite Negative Electrode and a Li2S-P2S5 Glassy Solid Electrolyte

Electrochemistry, 2022
All-solid-state lithium-ion batteries that use sulfide solid electrolytes have attracted much attention due to their high safety and wide electrochemical window. In this study, highly oriented pyrolytic graphite (HOPG) and 75Li2S-25P2S5 (mol%) glass were

Coordination-Driven Construction of Porphyrin Nanoribbons at a Highly Oriented Pyrolytic Graphite (HOPG)/Liquid Interface [PDF]

Journal of the American Chemical Society, 2019
Nanostructures were built at the solid/liquid interface by self-assembly and/or coordination bonds. Metalloporphyrins bearing two external coordination sites and long alkyl chains allowed the self-assembly of the compounds on highly oriented pyrolitic graphite.

Measurement of the longitudinal bunch-shape distribution for a high-intensity negative hydrogen ion beam in the low-energy region

Physical Review Accelerators and Beams, 2023
A bunch-shape monitor (BSM) is a useful device for performing longitudinal beam tuning using the pointwise longitudinal phase distribution measured at selected points in the beam transportation.

Discrimination of different amorphous carbon by low fluence laser irradiation

Carbon Trends, 2022
Carbon thin film depositions were carried out with femtosecond laser ablation from two different sp2-bonded carbon targets, namely highly oriented pyrolytic graphite (HOPG) and glassy carbon (GC).

Fundamental Study for a Graphite-Based Microelectromechanical System

Micromachines, 2018
We aimed to develop a process for constructing a carbon-based microelectromechanical system (MEMS). First, we prepared a highly oriented pyrolytic graphite (HOPG) crystal microsheet by exfoliation.

Enhanced percolative spin-glass-like behavior in oxygen-rich highly oriented pyrolytic graphite with anomalous non-hexagonal superlattices and doubled electron diffraction patterns

Carbon Trends, 2021
The recent observations of superconductive-signals in grafoil and highly-oriented-pyrolytic-graphite (HOPG) have evidenced existence of unknown-defects responsible of electron-correlation-phenomena.
