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 ...

Depletion interactions caused by polydisperse platelets

, 2011
We investigate depletion interactions near a wall caused by polydisperse silica-coated gibbsite platelets, using total internal reflection fluorescence microscopy (TIRF) to characterize the sphere-wall interaction potential.

Clay goes patchy

, 2011
Empty liquids and equilibrium gels have so far been only theoretical possibilities, predicted for colloids with patchy interactions.

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.

Theoretical and Experimental Spectroscopic Analysis of Cyano-Substituted Styrylpyridine Compounds

, 2013
A combined theoretical and experimental study on the structure, infrared, UV-Vis and 1H NMR data of trans-2-(m-cyanostyryl)pyridine, trans-2-[3-methyl-(m-cyanostyryl)]pyridine and trans-4-(m-cyanostyryl)pyridine is presented.

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.

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+.

Tactoids of plate-like particles: size, shape, and director field

, 2011
We studied, by means of polarized light microscopy, the shape and director field of nematic tactoids as a function of their size in dispersions of colloidal gibbsite platelets in polar and apolar solvents.

Chemical control of colloidal self-assembly driven by the electrosolvation force

Nature Communications
Self-assembly of matter in solution generally relies on attractive interactions that overcome entropy and drive the formation of higher-order molecular and particulate structures.

Cell geometry and membrane protein crowding constrain Escherichia coli growth rate, overflow metabolism, respiration, and maintenance energy

FEBS Letters, EarlyView.
The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This
