A tetragonal molybdenum nitride (β-Mo2N) has been prepared by temperature programmed treatment of MoO3 in flowing N2 + H2 and for the first time shown to catalyze the liquid phase selective hydrogenation (T = 423 K; PH2=11bar) of a series of para-substitut ...
The synthesis of a cylindrical, imine-based cage composed of two trimeric metallamacrocycles is described. The cage acts as a heterotopic receptor for alkali metal cations. The small cations Li+, Na+, and K+ bind to the outside of the cage with good select ...
The decomposition pathway is crucial for the applicability of LiBH 4 as a hydrogen storage material. We discuss and compare the different decomposition pathways of LiBH 4 according to the thermodynamic parameters and show the experimental ways to realize t ...
We describe a new method for the solvent-free synthesis of borohydrides at room temperature and demonstrate its feasibility by the synthesis of three of the most discussed borohydrides at present: LiBH4, Mg(BH 4)2 and Ca(BH4)2. This new gas-solid mechanoch ...
Lithiumborohydride (LiBH4) contains 18.5 wt % hydrogen and exhibits a structural phase transition (orthorhombic→ hexagonal) at 381 K, which is associated with a large increase in hydrogen and lithium mobility in the solid. Confining metal hydrides in a nan ...
The decomposition pathway is crucial for the applicability of LiBH 4 as a hydrogen storage material. We discuss and compare the different decomposition pathways of LiBH 4 according to the thermodynamic parameters and show the experimental ways to realize t ...
The covalent attachment of poly(ethylene glycol) (PEG) to therapeutically active proteins (PEGylation) has become an important method to deal with the pharmacological difficulties of these polypeptides, such as short body-residence times and immunogenicity ...
The electrical conductivities of complex hydrides Li2(BH 4)(NH2) and Li4(BH4)(NH 2)3 consisting of (BH4)- and (NH2)- anions are investigated focusing on their low melting temperatures (365 K for Li2(BH4)(NH2) and 490K for Li4(BH4)(NH2)3). The two hydrides ...
Open-pore 99.99% pure Al and Al-5 wt.% Mg foam produced by replication, with pores either 400 or 75 gm in average diameter, are tested in compression with repeated relaxation cycles, at room temperature. Similar data are collected on pure aluminium. Estima ...
Functionalized pyrrolidinium compounds, 3-((2-hydroxyethylthio)methyl)-1,1,4-trimethylpyrrolidinium and 3-((2-carboxyethylthio)methyl)-1,1,4-trimethylpyrrolidinium chlorides, are prepared from N,N-diallyl-N,N-dimethylammonium chloride by radical thiol-ene ...
