Characterization of nanoblisters on HOPG surface [PDF]
Journal of Electrical Engineering, 2019 Abstract We report on influence of the surface functionalization on the properties of highly oriented pyrolytic graphite. The samples were processed in nitric acid and characterized by XPS, Raman and EDX spectroscopies, AFM, SEM and optical microscopy.

Study of NAP adsorption and assembly on the surface of HOPG [PDF]
Peptides, 2014 NAP is an octapeptide that has demonstrated a neuroprotective/therapeutic efficacy at very low concentrations in preclinical studies and in a number of clinical trials. Yet little is known about its structural organization at low concentrations. Here, we have employed atomic force microscopy to investigate NAP peptide assembly on graphite in aqueous ...

Large Area HOPG Monochromators with Low Mosaic [PDF]
Proceedings of the International Conference on Neutron Optics (NOP2017), 2018 Highly oriented pyrolytic graphite (HOPG) monochromators with low mosaic (grades PGCX04, PGCX05, ZYA, AGraphY, etc.) are only available up to a maximum size of 50 × 50 mm2. In particular for one-dimensional focusing, several monochromators have to be glued or screwed on a substrate to obtain a length of typically 150 mm.

Spontaneous deposition of Pt‐nanoparticles on HOPG surfaces [PDF]
Surface and Interface Analysis, 2015 Pt nanoparticles were spontaneously generated by immersion of a highly ordered pyrolytic graphite substrate in a 1 mM H 2 PtCl 6 + 0.05 M H 2 SO 4 plating solution using ...

Recrystallization of tubules from natural lotus (Nelumbo nucifera) wax on a Au(111) surface
Beilstein Journal of Nanotechnology, 2011 We present here the first results on the self-assembly of tubules of natural wax from lotus leaves on a single crystal Au(111) surface. A comparison of the tubule growth on Au(111) to that on HOPG is discussed.

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).

BiCl3, CuCl2 Intercalation into HOPG
Journal of the Japan Society of Powder and Powder Metallurgy, 2006 BiCl3 and CuCl2 reacted with HOPG (Highly Oriented Pyrolytic Graphite) in the various conditions. In the reaction of BiCl3 with CuCl2GIC, the only stage4 BiCl3GIC was obtained. In the reaction of CuCl2 and BiCl3 with HOPG, the coexistent substance of stage2 or 4 BiCl3GIC and stage2 or 4 CuCl2GIC was obtained. Composition of Cu and Bi was C20(CuCl2)0.74(

ESTIMATION OF THE REAL AREA OF AU NANOPARTICLES OVER HOPG USING ELECTROCHEMICAL TECHNIQUES
Anales (Asociación Física Argentina), 2021 The metallic electrodes show a high affinity for the electroadsorption processes of hydrogen and/or oxygen in acid solutions, so it is possible to characterize them by electrochemical techniques.

Growth and Characterization of Ultrathin Vanadium Oxide Films on HOPG
Nanomaterials, 2022 Integration of graphene into various electronic devices requires an ultrathin oxide layer on top of graphene. However, direct thin film growth of oxide on graphene is not evident because of the low surface energy of graphene promoting three-dimensional ...
