A new definition of coarse-grained quantities describing the dust flow in general relativity is proposed. It assigns the coarse-grained expansion, shear and vorticity to finite-size comoving domains… (More)
Metal-organic frameworks (MOFs) allow compositional and structural diversity beyond conventional solid-state materials. Continued interest in the field is justified by potential applications of… (More)
Propylene (propene) is one of the most important feedstocks in the chemical industry. It is a starting material for the synthesis of a wide variety of commodity chemicals ranging from small molecules… (More)
A halogenmethylsulfonyl moiety is incorporated in numerous active herbicides and fungicides. The synthesis of tribromomethyl phenyl sulfone derivatives as novel potential pesticides is reported. The… (More)
Reactions between O2 and organometallics with non-redox-active metal centers have received continuous interest for over 150 years, although significant uncertainties concerning the character and… (More)
