The implementation of crown ethers into the ligand of cobalt porphyrins benefits the electrochemical CO2 reduction in the several ways: (1) the reduction potential is lowered in presence of K+; (2) it boosts the CO generation in Zero‐Gap Electrolyzers and (3) ensures complex stability during electrolysis.

Twisted 1‐ and 2‐Azaperopyrenes: Synthesis, Structure, and Properties
ABSTRACT A synthesis of hitherto unknown 1‐ and 2‐azaperopyrenes, twisted nitrogen‐doped peropyrenes, is reported. The synthesis is based on a Brønsted acid‐mediated benzannulation of alkynes. Key alkyne intermediates are synthesized via two complementary routes, including a Pd/C‐catalyzed, copper‐ and amine‐free Sonogashira‐type coupling of (hetero ...

The politics of Istanbul's Ottoman heritage in the era of globalism [PDF]
History is not merely about events which remind of the past, it is also about political struggles in the present. This is particularly so in contemporary cultural markets where 'history' is increasingly produced and disseminated in a host of ...

Detection of Radical Anions by Electrospray‐Ionization Mass Spectrometry
The present study investigates the ability of electrospray‐ionization mass spectrometry to detect radical anions. For neutral analytes with high electron affinities, radical anions are formed by cathodic reduction and can be easily observed. In contrast, analytes with lower electron affinities require the addition of a reducing agent for the generation

Die Arktis bei 2,7 Grad globaler Erwärmung: Schwindende Landschaften
Eine dicke Eisschicht auf dem Ozean, hunderte Meter tief gefrorener Boden und ein über 3 000 m hoher Eisschild – diese einzigartige Landschaft wird es vermutlich so in Zukunft nicht mehr geben. Eine globale Erwärmung von 2,7 °C, auf die wir aktuell zusteuern, würde die Arktis bis zur Unkenntlichkeit verändern.

This study develops a novel application of UAV‐LiDAR and Red Green Blue (RGB) data and network analysis to enhance our understanding of boreal forest succession. The results indicate that tree height and spectral variables are the most influential predictors of plant functional type in random forest algorithms, and high overall accuracies were attained.
