β‐Turn Mimicking Crosslinking Provides Hyperstability and Fast Folding Kinetics for Short Collagen Triple Helices

open access: yesChemBioChem, EarlyView.
Collagen triple helices and β‐turns are compatible chemical motifs to fuse based on their identical H‐bond geometry. The resulting collagen triple helices are intramolecularly folded, exhibiting high stability and fast folding kinetics. Besides serving as a scaffold structure for designing short, stable, heterotrimeric collagen triple helices, the bis ...

Lumos: A β‐Diketone‐Derived Artificial Nucleobase Forming Inter‐Strand Complexes in DNA that Promote Lanthanoid Ion Luminescence

open access: yesChemistryEurope, EarlyView.
A novel artificial nucleobase, 1‐(3‐(hydroxymethyl)phenyl)‐3‐phenylpropane‐1,3‐dione (HdbmOR), bearing a β‐diketone functionality and designed to form inter‐strand complexes that resemble lanthanoid‐mediated base pairs, was developed. The antenna effect of HdbmOR promoting luminescence of EuIII and SmIII is retained upon incorporation into short ...

Post‐disturbance evolution of a prograded foredune barrier during a sustained dynamic restoration project—the role of wind speed, wind direction and vegetation

open access: yesEarth Surface Processes and Landforms, Volume 47, Issue 15, Page 3435-3452, December 2022., 2022
Comparative photographs showing the change in dune morphology and vegetation cover at Doughboy Bay following a 12–15‐year period of sustained Ammophila arenaria control; from (a) densely vegetated shore‐aligned A. arenaria foredunes, to (b) sparsely vegetated wind‐aligned Ficinia spiralis nebkha.

The Interplay of Single Ion Anisotropy and Magnetic 3 d‐4 f Interactions in VIII2LnIII2 Butterfly Complexes

open access: yesChemistryEurope, EarlyView.
The 3d–4f coupling constants and relative angles between distinct anisotropy axes in butterfly‐shaped VIII2LnIII2 (Ln=Y, Tb−Yb) metal‐organic molecular complexes are determined using combined high‐field EPR spectroscopy and magnetisation studies. The observed chemical trend sheds light on the electronic exchange mechanism and highlights the important ...

The role of riparian vegetation flexibility in a bio‐hydro‐morphodynamic simulation

open access: yesEarth Surface Processes and Landforms, Volume 47, Issue 15, Page 3481-3496, December 2022., 2022
We conducted a bio‐hydro‐morphodynamic simulation to clarify the impact of vegetation flexibility on river bedform development. The figure compares vegetation cover and height during a flooding of channels with flexible (top) and rigid vegetation (bottom). The figure indicates that flexible vegetation reduced its height.

Coordination Tailoring of Pt Single‐Atom Catalysts at Room Temperature and Their Exceptional Performance in Hydrogen Evolution Reaction

open access: yesCarbon Energy, EarlyView.
This study presents the fabrication of Pt SACs with a new type of coordination environment at room temperature by introducing the chemically driven NO2 sites for atomically immobilizing PtCl2 on two‐dimensional nitrogen‐doped carbon nanosheets. The result is that Pt SACs demonstrate long‐term durability in hydrogen evolution reactions due to their ...
