Water-induced correlation between single ions imaged at the solid-liquid interface

Kislon Voitchovsky, Peter Spijker, Maria Ricci

When immersed into water, most solids develop a surface charge, which is neutralized by an accumulation of dissolved counterions at the interface. Although the density distribution of counterions perpendicular to the interface obeys well-established theori ...

Charge Asymmetry at Aqueous Hydrophobic Interfaces and Hydration Shells

Sylvie Roke, Yixing Chen, Rüdiger Scheu, Kailash Chandra Jena

The solvation of ions in a dielectric continuum is symmetric with respect to the sign of the ionic charge. Yet, many phenomena show indirect evidence that water may have a preference for negative charge: the vast majority of biological membrane interfaces ...

Effects of antibacterial agents and drugs monitored by atomic force microscopy

Sandor Kasas, Giovanni Longo

Originally invented for topographic imaging, atomic force microscopy (AFM) has evolved into a multifunctional biological toolkit, enabling to measure structural and functional details of cells and molecules. Its versatility and the large scope of informati ...

Low Energy Collisions in Merged Neutral Molecular Beams

Benjamin Bertsche

Within this thesis two experiments will be described. In the first experiment a velocity filter was used to obtain a beam of polar molecules (ND3) with a translational temperature of less than 5K. For the first time the dynamics of individual rotational st ...

Identification of Tyrosine-Phosphorylated Peptides Using Cold Ion Spectroscopy

Vladimir Kopysov, Natalia Nagornova

The accurate and unambiguous detection of post-translational modifications in proteins and peptides remains a challenging task. We report here the use of cold ion spectroscopy for the identification of phosphorylated tyrosine residues in peptides. This app ...

25th Anniversary Article: Label-Free Electrical Biodetection Using Carbon Nanostructures

Klaus Kern, Kannan Balasubramanian

Nanostructures are promising candidates for use as active materials for the detection of chemical and biological species, mainly due to the high surface-to-volume ratio and the unique physical properties arising at the nanoscale. Among the various nanostru ...

Electrochemical oxygen reduction at soft interfaces catalyzed by the transfer of hydrated lithium cations

Hubert Girault, Pekka Eero Peljo, Thomas James Stockmann, Haiqiang Deng

The oxygen reduction reaction by decamethylferrocene (DMFc), triggered by hydrophilic metallic cations behaving as Lewis acids towards water molecules in a homogeneous organic phase reaction, was investigated using cyclic voltammetry at the water|1,2-dichl ...

How Accurately Can We Predict the Melting Points of Drug-like Compounds?

Luc Patiny

This article contributes a highly accurate model for predicting the melting points (MPs) of medicinal chemistry compounds. The model was developed using the largest published data set, comprising more than 47k compounds. The distributions of MPs in drug-li ...

Methane Clathrate Hydrate Nucleation Mechanism by Advanced Molecular Simulations

Simone Meloni

The nucleation mechanisms of methane hydrates are studied using well-tempered metadynamics and restrained molecular dynamics. The collective variables we used to follow the process are the methane-methane and methane-water coordination numbers, from which ...
