On the structure of (111) twist grain boundaries in diamond: atomistic simulations with Tersoff-type interatomic potentials
In nanocrystalline diamond thin films, the high grain boundary density and the associated grain boundary properties may dominate the overall material behavior. In the present work, we systematically investigate (111) twist grain boundaries in diamond carbo ...
PERGAMON-ELSEVIER SCIENCE LTD2021Dual-Facet Mechanism in Copper Nanocubes for Electrochemical CO2 Reduction into Ethylene
Raffaella Buonsanti, Jianfeng Huang, Giulia Mangione
The product selectivity in the electrochemical reduction of carbon dioxide depends on the structure of the copper electrode. Cube-shaped copper catalysts, enclosed by {100} terraces, {110} edges, and {111} corners, exhibit a size-dependent enhanced only se ...
2019Nanocrystalline Boron-Doped Diamond as a Corrosion-Resistant Anode for Water Oxidation via Si Photoelectrodes
Kevin Sivula, Jun Ho Yum, Ladislav Kavan, Florian Le Formal, Petr Ashcheulov
Due to its high sensitivity to corrosion, the use of Si in direct photoelectrochemical (PEC) water-splitting systems that convert solar energy into chemical fuels has been greatly limited. Therefore, the development of low-cost materials resistant to corro ...
AMER CHEMICAL SOC2018Enhancement of optical quality factor by thermal annealing of single crystal diamond micro-resonators
Niels Quack, Teodoro Graziosi, Sichen Mi
We report on the increase in optical quality factor of a suspended single crystal diamond micro-disk resonator by thermal annealing. The resonators are fabricated by Deep Reactive Ion Etching (DRIE) to obtain circular pillars in bulk single crystal diamond ...
IEEE2018Cleaning strategy for carbon-based electrodes: Long-term propofol monitoring in human serum
Giovanni De Micheli, Giovanni Boero, Francesca Stradolini, Irene Taurino, Tugba Kilic
In this work, we present a novel electrochemical cleaning procedure for long-term electrochemical monitoring of propofol by using boron-doped diamond (BDD) and pencil graphite electrode (PGE). Propofol is an anesthetic that is widely used for long-lasting ...
2018All-diamond functional surface micro-electrode arrays for brain-slice neural analysis
Ladislav Kavan, Michele Giugliano
Diamond-based microelectrode arrays were fabricated by using nanocrystalline diamond as an insulating layer and conductive boron-doped in order to used them for analysis of brain cortical slices. MEA surface is solely composed of diamond, exposed to the ce ...
Wiley-V C H Verlag Gmbh2017Tribocorrosion and electrochemical behaviour of nanocrystalline diamond coated Ti based alloys for orthopaedic application
Metallic implants such as hip and knee often fail due to the combined action of wear and corrosion. Nanocrystalline diamond (NCD) coatings on metallic implants can be a potential candidate to overcome this issue. In this work, we investigated the tribocorr ...
