The present invention relates to a depth filter layer with inorganic layer double hydroxide, a method for production thereof, a filtration device containing this, a method for the separation of at least one contaminant from at least one target product in a liquid medium by means of at least one upstream depth filter layer and the use of the depth filter layer for removal of contaminants. The depth filter layer selectively retains contaminants such as nucleic acids, while target proteins of biotechnological processes are transmissible into the filtrate.

Depth filter layer with inorganic layer double hydroxide

The invention relates to dicopper(I) oxalate complexes stabilized by neutral Lewis bases, such as alkenes or alkynes, and to the use of dicopper(I) oxalate complexes as precursors for the deposition of metallic copper, in which the neutral Lewis bases used are alkynes, alkenes, triarylphosphines, CO or isonitriles.

Dicopper(I) oxalate complexes as precursor for metallic copper deposition

Disclosed are compounds of formula (I) which compounds are useful as cocatalysts in olefinic polymerisation reactions, e.g., as Ziegler-Natta catalysts.

Oxygen-containing organoaluminium complexes as cocatalysts

The invention relates to dicopper(I) oxalate complexes stabilised by neutral Lewis base components and to the use thereof as precursors for the deposition of metallic copper. The neutral Lewis bases used are alkynes or alkenes containing at least one silyl or ester group, or nitrites, saturated or unsaturated nitrogen ligands, phosphites, trialkyl-phosphines or oxygen- or sulfur-containing ligands.
