Velocity map imaging has been a highly successful method to study molecular and chemical dynamics. In recent years, we have combined this method with ion-molecule reactive scattering experiments and studied the dynamics of several fundamental ion-molecule reactions. Here, we describe the main components of the experiment and discuss the most important limitations to the obtainable imaging resolution. Then, results from our group are presented for both cation and anion-molecule reactions. Specifically, the charge transfer reaction Ar + + N2 and the nucleophilic substitution reaction X - + CH3I (X = Cl, F, OH), including recent results on micro-solvated water cluster anions, are reviewed. Furthermore, new and open questions and several future directions for research on ion-molecule reactive scattering are mapped out. © 2014 the Owner Societies.

In this manuscript we present a new approach for the numerical solution of the Galactic Cosmic Ray propagation problem. We introduce a method using advanced contemporary numerical algorithms while retaining the general complexity of other established codes. In this paper we present the underlying numerical scheme in conjunction with tests showing the correctness of the scheme. Finally we show the solution of a first example propagation problem using the new code to show its applicability to Galactic Cosmic Ray propagation. © 2014 Elsevier B.V. All rights reserved.

A bacterium sees red: Chlorophyll f (Chl f), a tetrapyrrole displaying unprecedented red-shifted absorption bands, was discovered in cyanobacteria and its structure was deduced by spectroscopic means. The new chromophore of Chl f is likely a result of biological adaptation and biochemical optimization in bacteria in their struggle for survival. It is a sign of life's constant demand for energy obtained from sunlight through photosynthesis. Copyright © 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

The discovery of cisplatin's antitumor activity in 1969 prompted the search for novel metal-containing complexes as potential anticancer drugs. Among these novel complexes, metal N-heterocyclic carbene (NHC) complexes have recently gained considerable attention because they perfectly fit prerequisites for efficient drug design and fast optimization. Moreover, most of them have shown higher cytotoxicity than cisplatin. This review describes the advances that have been achieved in using transition metal (Ag, Au, Pt, Pd, Cu, Ni, and Ru) complexes containing NHC ligands as antitumor agents. Their modes of action at the cellular lever are further discussed. All these initial achievements clearly demonstrate the great potential of metal-NHC complexes as antitumor agents. © The Royal Society of Chemistry 2013.

Most of the syntheses in solid-state chemistry are performed at constant pressure of ∼1 atm (about 105 Pa) by the manipulation of the thermodynamic parameters temperature and composition, leading to a rich variety of compounds. In contrast, the additional variation of pressure has remained virtually unexplored, due to the relatively large costs of maintaining high-pressure conditions and the inevitably tiny sample volumes. In the last two decades, technical advances, developed for studying the properties of minerals, have found access into the preparative solid-state chemistry, opening up tremendously large areas to synthesize new materials. © 2011 The Royal Society of Chemistry.
