Angewandte Chemie, EarlyView.It may seem counterintuitive to first target a ruthenium alkylidyne when Grubbs‐type ruthenium carbene complexes are the actual goal. In the end, however, this tactic pays valuable dividends in terms of practicality, atom economy, flexibility as well as safety: the new route provides ready access to a large assortment of catalysts for alkene metathesis

Metal-hydrogen systems with an exceptionally large and tunable thermodynamic destabilization
Nature Communications, 2017 Tailoring the thermodynamics of metal-hydrogen interactions is crucial for tuning the properties of metal hydrides but remains difficult to control. Here, the authors create an yttrium hydrogen sensor sensitive to pressure changes of up to four orders of

Angewandte Chemie, EarlyView.A NiH‐catalyzed α‐alkenylation via Markovnikov hydronickellation of alkynes enables convenient access to α‐chrial β‐methylene carbonyl frameworks that are prevalent in biorelevant molecules. High regio‐ and enantioselectivities have been achieved with excellent functional group tolerance and applicability toward complex structures. The β‐methylene unit

Low to high temperature energy conversion system [PDF]
, 1977 A method for converting heat energy from low temperature heat sources to higher temperature was developed. It consists of a decomposition chamber in which ammonia is decomposed into hydrogen and nitrogen by absorbing heat of decomposition from a low ...

Angewandte Chemie, EarlyView.Rh‐catalyzed chemodivergent parallel kinetic resolution of racemic 1,6‐enynes with α‐fluoroacrylamides or mixtures of different acrylamides proceeded via [2+2+2] cycloaddition and C–H alkylation to afford structurally and stereochemically distinct products with high selectivity under mild conditions.

Angewandte Chemie, EarlyView.Der bimetallische M14‐Cluster [Co3Ga2]H(μ2‐GaTMP)9 wurde durch einen ko‐reduktiven Ansatz erzielt. Dieser Ansatz nutzt Mg und H2, um den Ga‐TMP‐Liganden selektiv zu entschützen und das TMP abzufangen, was zur Bildung eines gemischtmetallischen Co/Ga Clusterkerns führt, was diesen zu einem strukturellen Vertreter eines vergleichbaren Gegenstücks der ...

Interface Enthalpy-Entropy Competition in Nanoscale Metal Hydrides
Inorganics, 2018 We analyzed the effect of the interfacial free energy on the thermodynamics of hydrogen sorption in nano-scaled materials. When the enthalpy and entropy terms are the same for all interfaces, as in an isotropic bi-phasic system, one obtains a ...

Performance analysis of advanced spacecraft TPS [PDF]
The analysis on the feasibility for using metal hydrides in the thermal protection system of cryogenic tanks in space was based on the heat capacity of ice as the phase change material (PCM).
