Angewandte Chemie 23/2016: Resistance is Futile

Angewandte Chemie 23/2016: Resistance is FutileIn this issue, R. Riedl et al. review the targeting of antibiotic resistance. What promise do structure-based and mechanism-based approaches as well as interventions into the genome hold? In a Minireview, T. Weil et al. discuss diamond quantum devices in biology.

In the Communications section, C. Giansante et al. look at the dynamic interface of PbS quantum dots (see picture). Y. Wang et al. describe molecularly regulated reversible DNA polymerization. K. Tanaka et al. succeeded in rhodium-catalyzed cross-cyclotrimerizations and dimerizations of allenes with alkynes, and G. Schneider et al. used computational de novo design to go from from natural products to synthetic mimetics.

Hot Paper: Modification of Wide-Band-Gap Oxide Semiconductors with Cobalt Hydroxide Nanoclusters for Visible-Light Water Oxidation

Modification of Wide-Band-Gap Oxide Semiconductors with Cobalt Hydroxide Nanoclusters for Visible-Light Water Oxidation

When rutile TiO2, a wide-band-gap semiconductor, is modified with cobalt hydroxide nanoclusters, it can be used for photocatalytic water oxidation under visible-light irradiation at wavelengths of up to 850 nm. This material thus constitutes the first particulate photocatalyst that operates at such long wavelengths.

Hot Paper: The Nanoparticle Size Effect in Graphene Cutting: A “Pac-Man” Mechanism

The Nanoparticle Size Effect in Graphene Cutting: A “Pac-Man” Mechanism

Surface or interface? By employing a multiscale simulation approach, a “Pac-Man” mechanism is revealed for the nickel-nanoparticle-catalyzed cutting of graphene. Although the overall cutting rate is proportional to the surface area of the nanoparticle, it is found that the rate-limiting step is actually at the graphene–metal interface instead of on the nanoparticle surface.

Hot Paper: Low-Temperature Cationic Rearrangement in a Bulk Metal Oxide

Low-Temperature Cationic Rearrangement in a Bulk Metal Oxide

The unprecedented low-temperature (150–300 °C) cationic rearrangement in bulk Mn2FeMoO6 leads to a transition from a Ni3TeO6-type to an ordered-ilmenite structure, and dramatic changes of the electrical and magnetic properties, which demonstrates remarkable physical property tunneling through atomic-scale manipulation in bulk oxide under mild conditions.

Hot Paper: Chromoselective Photocatalysis: Controlled Bond Activation through Light-Color Regulation of Redox Potentials

Chromoselective Photocatalysis: Controlled Bond Activation through Light-Color Regulation of Redox Potentials

I see your two colors, shining through: The xanthene dye rhodamine 6G is a moderately reducing photoredox catalyst if irradiated with green light, but provides an high reduction power of −2.4 V vs. SCE upon blue-light irradiation. This allows control of the selectivity of photocatalytic C−H arylation reactions through changing the color of the light.

Hot Paper: Autocrine-Based Selection of Drugs that Target Ion Channels from Combinatorial Venom Peptide Libraries

Autocrine-Based Selection of Drugs that Target Ion Channels from Combinatorial Venom Peptide Libraries

Pick your poison: Cysteine-knot peptides were extracted from the venom database by using bioinformatics and used to create a lentiviral vector library for the autocrine-based selection of peptides targeting ion channels. Interaction of the membrane-tethered venom peptide with the ion channel results in the protease-mediated release of a transcription factor (orange), which triggers expression of a reporter gene (red).

VIP: Stable Aqueous Photoelectrochemical CO2 Reduction by a Cu2O Dark Cathode with Improved Selectivity for Carbonaceous Products

Stable Aqueous Photoelectrochemical CO2 Reduction by a Cu2O Dark Cathode with Improved Selectivity for Carbonaceous Products

Copper on the dark side: Cu2O preferentially reduced CO2 to fuels while suppressing hydrogen evolution. It was found that the photogenerated holes primarily account for the instability of Cu2O. The Cu2O was used as a dark cathode to minimize the adverse effects of holes, achieving excellent stability and a selectivity of 92.6 % for carbonaceous products in CO2 photoreduction.

Hot Paper: Dissipative and Autonomous Square-Wave Self-Oscillation of a Macroscopic Hybrid Self-Assembly under Continuous Light Irradiation

Dissipative and Autonomous Square-Wave Self-Oscillation of a Macroscopic Hybrid Self-Assembly under Continuous Light Irradiation

Oscillate wildly: In a limit-cycle self-oscillatory motion of a macroscopic assembly, the assembly permanently flips under continuous blue-light irradiation. Mechanical self-oscillation showing a spatio-temporal pattern is established by successively alternating photoisomerization processes and multi-stable phase transitions.

Nitrogen-Rich Manganese Oxynitrides with Enhanced Catalytic Activity in the Oxygen Reduction Reaction

The catalytic activities of manganese oxynitrides with different nitrogen contents in the oxygen reduction reaction (ORR) in alkaline solution were investigated. An increase in the nitrogen content of rock-salt-type manganese oxynitrides increases the valence of manganese and leads to enhanced catalytic activity.

Angewandte Chemie 22/2016: Fighting Diseases

Angewandte Chemie 22/2016: Fighting DiseasesIn this issue, K. H. van Pée et al. review specific enzymatic halogenation. How were halogenated enzymes discovered and how are they used in vivo and in vitro? The Highlight deals with the rational design of proteasome inhibitors as antimalarial drugs (C. Le Chaplain and M. Groll).

In the Communications section, F. Würthner et al. report on an electron-poor nanographene they made by cascade C–C bond formation reactions. P. M. O'Neill et al. describe a proteomic approach to reveal the protein alkylation profile of antimalarials. J. Luo et al. discovered a photoferroelectric organometallic halide with strongly anisotropic photovoltaic properties, and T. Kondo et al. discuss a CRISPR/Cas9 method for targeted transcriptional activation.
