Biomimetic light-harvesting funnels for re-directioning of diffuse light

Nature Communications, 2018
Sunlight harvesting and redirection is a promising concept for sustainable energy conversion, however losses have hindered progress. Here the authors construct a simple biomimetic device which minimises losses by using reservoirs of randomly-oriented ...

λ/2 Fabry Pérot micro-resonators in single molecule spectroscopy

EPJ Web of Conferences, 2018
Embedded in a tuneable λ/2-FabryPérot micro-resonator the radiative relaxation of a dye molecule or quantum dot can reproducibly be modified allowing to determine their quantum yield, control Förster energy-transfer or localize them with nanometer ...

Synthesis of Nanometer Sized Bis- and Tris-trityl Model Compounds with Different Extent of Spin–Spin Coupling

Molecules, 2018
Tris(2,3,5,6-tetrathiaaryl)methyl radicals, so-called trityl radicals, are emerging as spin labels for distance measurements in biological systems based on Electron Paramagnetic Resonance (EPR).

Understanding the Sensing Mechanism of Rh₂O₃ loaded In₂O₃

Proceedings, 2018
The effect of Rh loading on CO sensing was studied for the case of In2O3. This was done by performing measurements with sensors based on loaded and unloaded materials that were performed at an operation temperature of 300 °C in the presence of low ...

Strong inverse kinetic isotope effect observed in ammonia charge exchange reactions

Nature Communications, 2020
Inverse kinetic isotope effects (KIEs) are rarely observed. Here, the authors report an inverse KIE in the charge transfer reaction of $${{\rm{Xe}}}^{+}$$ Xe+ with ammonia.

Integrating mass spectrometry with MD simulations reveals the role of lipids in Na+/H+ antiporters

Nature Communications, 2017
Na+/H+antiporters transport sodium or lithium ions across the membrane in exchange for protons. Here the authors combine ion mobility mass spectrometry and molecular dynamics simulations to uncover a facilitating role for lipids in the transport ...

UnidecNMR: automatic peak detection for NMR spectra in 1-4 dimensions

Nature Communications
To extract information from NMR experiments, users need to identify the number of resonances in the spectrum, together with characteristic features such as chemical shifts and intensities.

Ionic Liquids Based on the Concept of Melting Point Lowering Due to Ethoxylation

Molecules, 2021
Most of the commonly used Ionic Liquids (ILs) contain bulky organic cations with suitable anions. With our COMPLET (Concept of Melting Point Lowering due to Ethoxylation), we follow a different approach.

Calpain small subunit homodimerization is robust and calcium‐independent

FEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.
