Templated Synthesis of Diamond Nanopillar Arrays Using Porous Anodic Aluminium Oxide (AAO) MembranesZhang, C. (author), Liu, Z. (author), Li, Chun (author), Buijnsters, J.G. (author)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...journal article 2023

Suresh Babu, Diwakar (author), Mol, J.M.C. (author), Buijnsters, J.G. (author)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...journal article 2022

(author)Nitrogen-vacancy (NV) magnetometry is a new technique for imaging spin waves in magnetic materials. It detects spin waves by their microwave magnetic stray fields, which decay evanescently on the scale of the spin-wavelength. Here, we use nanoscale control of a single-NV sensor as a wavelength filter to characterize frequency-degenerate spin...journal article 2022

Rhebergen, Damiaan (author)The Cluster Editing problem asks to transform a graph into a union of disjoint cliques in the minimum number of edge additions and deletions. The Cluster Deletion problem has the same goal, but allows edge deletions only. Recently, a connection between Cluster Editing on diamond-free graphs and Cluster Deletion was established. In this paper we...bachelor thesis 2021
