Supramolecular Host‐Guest Complexation Dynamics by Cost‐Efficient Electronic Structure Methods

open access: yesChemistry – A European Journal, EarlyView.
We present a cost‐effective multilevel workflow for the kinetic profiling of host–guest systems, illustrated with cucurbit[6]uril and alkylammonium cations. The method combines rapid docking and reaction path searches at the semi‐empirical level, with refinement of the results using modern density functional theory, accurately reproducing experiment ...

Insights into species diversity of associated crustose coralline algae (Corallinophycidae, Rhodophyta) with Atlantic European maerl beds using DNA barcoding

open access: yesAnales del Jardín Botánico de Madrid, 2017
DNA barcoding in combination with morpho-anatomical analysis was applied to study the diversity of crustose coralline algae associated to two maerl beds from two protected Atlantic European areas from Brittany and Galicia —France and Spain, respectively—.

Tuning the Twist by Molecular Design: A New Strategy for Hexabenzocoronene‐Containing Helical Twistacene

open access: yesChemistry – A European Journal, EarlyView.
An efficient Scholl–based strategy enables precise control of the C–C bond to access the first hexabenzocoronene–containing helical twistacene (NG2). The resulting nanographene shows pronounced helical distortion, high stability, enhanced solubility, and promising redox and optoelectronic properties.

The Electronic Spin State of Diradicals Obtained from the Nuclear Perspective: The Strange Case of Chichibabin Radicals

open access: yesChemPhysChem, Volume 26, Issue 6, March 15, 2025.
The electronic spin state of two Chichibabin radicals is investigated using 2‐dimensional hyperfine correlated Electron Nuclear Double Resonance. The protons (I=1/2) act as a reference for the electronic spin quantum number (S) via their hyperfine interactions.

Powerful yet challenging: mechanistic niche models for predicting invasive species potential distribution under climate change

open access: yesEcography, EarlyView.
Risk assessments of invasive species present one of the most challenging applications of species distribution models (SDMs) due to the fundamental issues of distributional disequilibrium, niche changes, and truncation. Invasive species often occupy only a fraction of their potential environmental and geographic ranges, as their spatiotemporal dynamics ...
