Organocatalytic Asymmetric Cyanosilylation of Nitroalkenes
A new catalyst type for a new reaction. The unprecedented cyanosilylation of nitroalkenes can be efficiently catalyzed by a bifunctional quinine derivative bearing tetra-alkylammonium cyanide and thiourea moieties. The activation of the nitroalkene by H-bonding to the...
Inhibition of Target of Rapamycin signaling and stress activate autophagy in Chlamydomonas reinhardtii
Autophagy is a catabolic membrane-trafficking process whereby cells recycle cytosolic proteins and organelles under stress conditions or during development. This degradative process is mediated by autophagy-related (ATG) proteins which have been described in yeasts,...
Fra proteins influencing filament integrity, diazotrophy and localization of septal protein SepJ in the heterocyst-forming cyanobacterium Anabaena sp.
Anabaena sp. strain PCC 7120 is a filamentous cyanobacterium that can fix N2 in differentiated cells called heterocysts, which exchange nutritional and regulatory compounds with the neighbouring photosynthetic vegetative cells. The cells in the filament appear to be...
Oxidation state and local structure of Ti-based additives in the Reactive Hydride Composite 2LiBH4 + MgH2
Nowadays, the technological utilization of Reactive Hydride Composites (RHC) as hydrogen storage materials is limited by their reaction kinetics. However, addition of transition metal based additives, for instance titanium isopropoxide (Ti-iso), to the 2LiBH4+MgH2...
