Electrochemical study about zinc electrodeposition onto GCE and HOPG substrates [PDF]

open access: yesQuímica Nova, 2011
We carried out an electrochemical study about zinc electrodeposition onto GCE and HOPG substrates from an electrolytic plating bath containing 0.01M ZnSO4 + 1M (NH4)2SO4 at pH 7.

Self-assembly and wetting properties of gold nanorod–CTAB molecules on HOPG [PDF]

open access: yesBeilstein Journal of Nanotechnology, 2019
The formation of self-assembled superstructures of cetyltrimethylammonium bromide (CTAB) after drying on a nonwetting highly ordered pyrolytic graphite (HOPG) surface have been investigated using scanning electron microscopy (SEM) and atomic force ...

Probing Type-II Multiferroicity in Monolayer NiBr<sub>2</sub>. [PDF]

open access: yesAdv Sci (Weinh)
Type‐II multiferroicity is demonstrated in monolayer NiBr2. Scanning tunneling microscopy resolves ferroelectric polarization arising from non‐collinear magnetic order, and reciprocal control with electric and magnetic fields confirms intrinsic magnetoelectric coupling.

Raman study of the interactions between highly ordered pyrolytic graphite (HOPG) and polyoxometalates: The effects of acid concentration [PDF]

open access: yesJournal of the Serbian Chemical Society, 2016
Heteropoly acids (HPAs) found wide applications, such as in catalysis, energy conversion and storage, analytical chemistry, clinical medicine, materials science and others, but because of their low surface area and high solubility in water their

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

open access: yesPhysical 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.

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

open access: yesCarbon 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.

Re-Oxidation of ZnO Clusters Grown on HOPG [PDF]

open access: yesCoatings, 2020
This article studies the chemical interaction between ZnO and highly oriented pyrolytic graphite for as grown and thermally treated samples. In-situ X-ray photoelectron spectroscopy and ex-situ Raman spectroscopy confirm that graphite is affected by these processes, becoming oxidized and defective only in the presence of ZnO clusters that become ...

Comparison of the Electrochemical Response of Carbon-Fiber-Reinforced Plastic (CFRP), Glassy Carbon, and Highly Ordered Pyrolytic Graphite (HOPG) in Near-Neutral Aqueous Chloride Media

open access: yesC, 2023
Carbon-fiber-reinforced polymers (CFRP), being conductive, are capable of supporting cathodic oxygen reduction reactions (ORR) and thus promote galvanic corrosion when coupled to many metallic materials.

HOPG/ZnO/HOPG pressure sensor

open access: yesJournal of Physics: Conference Series, 2017
Pressure sensor is one of the most commonly used sensors in the research laboratories and industries. These are generally categorized in three different classes of absolute pressure sensors, gauge pressure sensors, and differential pressure sensors. In this paper, we fabricate and assess the pressure sensitivity of the current vs. voltage diagrams in a

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.
