A Mononuclear Ruthenium(V)‐Imido Complex With Hydrogen Bonding in the Second Coordination Sphere Forming Aziridines Without N‐Substituents From Alkenes in Water

Angewandte Chemie, EarlyView.
This study employs a RuV═NH complex with hydrogen‐bonding (HB) sites in the SCS to afford non‐N‐substituted aziridines selectively. Nitrogen‐atom transfer occurs from the RuV═NH complex to alkenes in water to produce aziridine derivatives in high yields.

Metal‐free Hydrogen Generation from Seawater and Silicon Waste: A Circular Approach

Angewandte Chemie, EarlyView.
Hydrogen was rapidly generated directly from untreated seawater and polymeric Si waste without any transition metal catalyst. The in situ generated polymeric cross‐linked Si resin was completely depolymerized under mild conditions into chloro‐silane monomers.

Destabilization of lithium borohydride with additions of magnesium hydride

, 2010
It has been shown that lithium borohydride can be destabilized with magnesium hydride additions for the purpose of reversibly hydrogen. In reactive composites of these hydrides alternative chemical pathways become available for dehydrogenation, which can

Electroenzymatic CO2 Fixation

Angewandte Chemie International Edition, EarlyView.
Electroenzymatic CO2 fixation enables energy‐efficient, highly selective synthesis of complex molecules. Unlocking its full potential requires fundamental understanding of electrode‐coupled reductases and carboxylases. This review critically discusses available enzymes, product scope, and key thermodynamic and kinetic considerations, highlighting ...

Processing of Ti/SiC composites: a comparative study of the foil-fibre-foil and the tape-casting techniques

, 1997
Ti-based SiC fibre reinforced composites are strong, stiff and light-weight materials for high temperature applications up to 600-800°C. As with any other advanced materials, their development has to overcome both economic and technical hurdles.
