Electrochemical wastewater treatment is a promising technique to remove recalcitrant pollutants from wastewater. However, the complexity of elucidating the underlying degradation mechanisms hinders its optimisation not only from a techno-economic perspective, as it is desirable to maximise removal efficiencies at low energy and chemical...

Diamond nanostructures are mostly produced from bulk diamond (single- or polycrystalline) by using time-consuming and/or costly subtractive manufacturing methods. In this study, we report the bottom-up synthesis of ordered diamond nanopillar arrays by using porous anodic aluminium oxide (AAO). Commercial ultrathin AAO membranes were adopted as...

Polycrystalline boron-doped diamond (BDD) films were surface nanotextured by femtosecond pulsed laser irradiation (100 fs duration, 800 nm wavelength, 1.44 J cm<sup>−2</sup> single pulse fluence) to analyse the evolution of induced alterations on the surface morphology and structural properties. The aim was to identify the occurrence of laser...

In this work, three distinct heteroepitaxial single-crystal boron-doped diamond (SC-BDD) electrodes were fabricated and subjected to detailed surface analysis and electrochemical characterization. Specifically, the heteroepitaxy approach allowed to synthesize large-area (1 cm<sup>2</sup>) and heavily-doped (100)-oriented SC-BDD electrodes....

In this work, non-modified boron-doped diamond (BDD) was employed first time ever as the sensing material for the in-depth voltammetric study of the antiretroviral drug nevirapine (NVP) used to treat HIV infections. Two types of electrode surface pre-treatments, anodic oxidation and alumina-polishing, yielded BDD of different surface...

In this paper, the effect of boron doping on the electrical, morphological and structural properties of free-standing nanocrystalline diamond sheets (thickness ~ 1 μm) was investigated. For this purpose, we used diamond films delaminated from a mirror-polished tantalum substrate following a microwave plasma-assisted chemical vapor deposition...

GenX is the trade name of the ammonium salt of hexafluoropropylene oxide dimer acid (HFPO-DA) and is used as a replacement for the banned perfluorooctanoic acid (PFOA). However, recent studies have found GenX to be more toxic than PFOA. This work deals with the electrochemical degradation of HFPO-DA using boron-doped diamond anodes. For the...

Black liquor (BL) is a highly alkaline byproduct from pulp mills. BL is rich in inorganic and organic compounds, with lignin (a natural polymer) being the most abundant. Following a waste biorefinery concept, the electrolysis of BL comprises lignin oxidation at the anode and hydrogen evolution at the cathode. These paired electrochemical...

Boron-doped diamond (BDD) is of increasing interest for applications in electrochemical sensing. It is well known that the sp<sup>2</sup> carbon content in BDD influences its electrochemical properties as electrode material. In this work, evidence is provided that the surface sp<sup>2</sup> carbon content plays a crucial role in the...

Self-organized anodization of copper in 0.1 M Na2CO3 electrolyte was studied in order to obtain nanostructured oxide surface on the metal substrate. Linear sweep voltammetry (LSV) revealed that the most suitable voltage range for anodic film formation is from 3 to 31 V. In this range (except between 3 and 7 V), the oxide is formed as nanorods,...

Micropillar adhesives have gained increasing attention because they generate high pull-off forces. The generation of high friction, however, has been proven difficult with such geometries, because micropillars tend to buckle under shear loading. Here, we fabricated orthogonal arrays of composite poly-dimethoxysiloxane (PDMS) micropillars with...
