Edge functionalisation of graphene nanoribbons with a boron dipyrrin complex : a thesis presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Nanoscience at Massey University, Manawatū, New Zealand [PDF]

open access: yes, 2017
Chemical modification can be used to tune the properties of graphene and graphene nanoribbons, making them promising candidates for carbon-based electronics.

GraphReco: Probabilistic Structure Recognition for Chemical Molecules

open access: yesChemistryOpen, EarlyView.
Molecule structure images are unfriendly for machine understanding, blocking productivity improvements in chemical data mining, drug discovery, and many other fields. We present a rule‐based probabilistic Optical Chemical Structure Recognition model to explain and tackle the ambiguity challenges in graph assembly.

Adaptive, but Equitable? Exploring the Impact of Machine Learning‐Based Adaptive Support on Educational Debts in Undergraduate Chemistry

open access: yesScience Education, EarlyView.
ABSTRACT Students' diverse levels of knowledge and competence—shaped by individual interests and educational debts, including structural, systemic, and institutional barriers—create substantial cognitive heterogeneity in instructional settings. Adequately addressing this heterogeneity is challenging.

Modular Donor‐Acceptor Diradicaloids Based on an Electron Deficient N‐Heteroacene Acceptor

open access: yesSmall, EarlyView.
This work presents a modular approach to donor‐acceptor‐donor (D‐A‐D) diradicaloids that show systematic evolution of their energy gaps, singlet‐triplet splittings, and diradical character (y). The correlation of (opto)electronic, spin, and magnetic properties with high‐fidelity theoretical investigations provides clear connections between the degree ...

Harnessing Non‐Covalent Protein–Protein Interaction Domains for Production of Biocatalytic Materials Systems

open access: yesAdvanced Functional Materials, Volume 36, Issue 11, 5 February 2026.
Non‐covalent protein–protein interactions mediated by SH3, PDZ, or GBD domains enable the self‐assembly of stable and biocatalytically active hydrogel materials. These soft materials can be processed into monodisperse foams that, once dried, exhibit enhanced mechanical stability and activity and are easily integrated into microstructured flow ...

Fluorescence for high school students [PDF]

open access: yes, 2012
In a not obligatory series of lessons for high school students in the Netherlands we discuss the fluorescence aspects of anthracene. These lessons were developed because HiSPARC (High school Project on Astrophysics Research with Cosmics) detection of ...

Temporal fluctuations in excimer-like interactions between pi-conjugated chromophores

open access: yes, 2015
Inter- or intramolecular coupling processes between chromophores such as excimer formation or H- and J-aggregation are crucial to describing the photophysics of closely packed films of conjugated polymers.

Modular Amphiphilic Design Enables Control of Oblique vs J‐Type Exciton Coupling in Aqueous Self‐Assembly

open access: yesChemistryEurope, Volume 4, Issue 2, February 2026.
Herein, a family of amphiphilic aza‐BODIPY dyes is rationally designed to precisely control the type of exciton coupling (oblique vs J‐type) and the nanoscale morphology in aqueous media. By systematically varying the hydrophilic and hydrophobic substituents, new structure–property relationships that extend the understanding beyond traditional ...
