53_30/2014Cover Picture: Single-Particle Tracking and Modulation of Cell Entry Pathways of a Tetrahedral DNA Nanostructure in Live Cells (Angew. Chem. Int. Ed. 30/2014)

Tetrahedral DNA nanostructures can be readily taken up by cells. In their Communication on page 7745 ff., C. Fan, Q. Huang, and co-workers investigate the endocytotic internalization into mammalian cells and subsequent transport of these self-assembled DNA nanostructures by single-particle tracking. These results constitute the next step toward the development of novel drug-delivery systems based on nucleic acids.

Gas-Phase Chemistryfor001

In their Communication on page 7740 ff., R. I. Kaiser, M. Ahmed et al. use photo-ionization mass spectrometry to show the formation of naphthalene in the gas phase through the reaction of a phenyl radical with two acetylene molecules.


Electrocatalysisfor002

A high-temperature solution-phase method for the synthesis of ultrathin WS2 nanoflakes is introduced by Z. Liu, Y. G. Li et al. in their Communication on page 7860 ff.


Lithium-Ion Batteriesfor003

In their Communication on page 7864 ff., Y. Wang, H. Peng et al. describe a wire-shaped lithium-ion battery that consists of two composite yarns, made from aligned multi-walled carbon nanotubes and lithium oxides, as the anode and cathode.


53_30i/2014Inside Cover: A General Copper-Mediated Nucleophilic 18F Fluorination of Arenes (Angew. Chem. Int. Ed. 30/2014)

Radiolabeling of arenes with [18F]fluoride by a transformational method using readily available aryl boronic ester precursors is reported by V. Gouverneur and co-workers in their Communication on page 7751 ff. The picture illustrates, in the confinement of a PET (positron emission tomography) scanner, the annihilation event resulting from positron emission from [18F]fluoro-l-DOPA.

53_30c/2014Inside Back Cover: Ultrathin WS2 Nanoflakes as a High-Performance Electrocatalyst for the Hydrogen Evolution Reaction (Angew. Chem. Int. Ed. 30/2014)

WS2 nanoflakes with monolayer thickness and abundant edges were synthesized through a high-temperature solution-phase method that is described by Z. Liu, Y. G. Li et al. in their Communication on page 7860 ff. These nanoflakes exhibited impressive activity and durability in electrocatalytic hydrogen-evolution reactions in acids and thus represent an attractive low-cost alternative to the precious platinum benchmark catalyst.

53_30b/2014Back Cover: Elastic and Wearable Wire-Shaped Lithium-Ion Battery with High Electrochemical Performance (Angew. Chem. Int. Ed. 30/2014)

A safe wire-shaped lithium-ion battery consists of two composite yarns, which were prepared from aligned multi-walled carbon nanotubes and lithium oxides, as the anode and cathode. In their Communication on page 7864 ff., Y. Wang, H. Peng et al. describe that 97 % of the capacity of these lightweight and flexible batteries was retained after 1000 bending cycles. Furthermore, the wire-shaped batteries were woven into battery textiles.
