Nanocrystalline Metal/Metal Hydrides for Fuel Cell Applications
, 2006 Formation of nanocrystalline films by low temperature deposition of metallic films was investigated with special emphasis for hydrogen storage. Large grain boundary volume associated with nanocrystalline films was shown to be favorable for hydrogen ...

Die Aza‐Büchner–Curtius–Schlotterbeck‐Reaktion: Selektive Bildung Quartärer Kohlenstoffzentren
Angewandte Chemie, EarlyView.Wir stellen die Aza‐Büchner–Curtius–Schlotterbeck‐(ABCS)‐Reaktion vor: eine milde, katalysatorfreie Methode zur Homologierung von Aryliminen. Im Gegensatz zum traditionellen BCS‐Mechanismus durchläuft das Diazo‐Intermediat eine selektive C─C‐Insertion zur Bildung eines quartären Zentrums.

Engineering Ferrimagnetic Interactions in Molecular Quantum Systems
Angewandte Chemie, EarlyView.Heterospin nanographene architectures—constructed by covalently linking spin‐1/2$\nicefrac {1}{2}$ and spin‐1 triangular units via on‐surface synthesis—are characterized by bond‐resolved scanning probe microscopy. Inelastic electron tunneling spectroscopy probes exchange interactions within a Heisenberg model, revealing both compensated (S=0$S=0$) and ...

The SO-effect in transition metal hydrides [PDF]
, 2005 The goal of this report is to estimate the Spin-Orbit effect on the ground state energies, bond lengths, ground state frequencies and formation energies for transition metal hydrides of the form $MH_2$, $MH_4$, $MH_6$ and $MH_{12}$ where M could be Cr ...

Angewandte Chemie, EarlyView.Merging silylium‐ion and palladium catalysis provides a mechanistically distinct route to allylsilanes by formal C–H/Si–H metathesis. Using allylsilanes as silicon proelectrophiles, various allylarenes undergo migrative silylation, selectively yielding (E)‐allylsilanes.

Preparation of lanthanide hydrides of nanometric size by the catalytic method
, 2002 Rare-earth metals were hydrogenated in the presence of TiCl4 catalyst in tetrahydrofuran (THF) at 45 degreesC under normal pressure. Transmission electron micrographs showed that the re. sulting lanthanide hydrides were in the form of nanoparticles.

Anion Engineering of Surface Frustrated Lewis Pairs for Light‐Assisted CO2 Hydrogenation to Methanol
Angewandte Chemie, EarlyView.Anion engineering through nitrogen incorporation regulates the local coordination environment and promotes the formation of defect‐associated Ga–O/N frustrated Lewis pairs in non‐stoichiometric zinc gallium oxide. The engineered surface sites facilitate heterolytic H2 splitting, while the modified electronic structure enhances light utilization ...
