Chirality from scratch: enantioselective adsorption in geometrically controlled lateral nanoconfinement

Enantioselective adsorption in achiral zeolites.

Dynamic control of chirality in phosphine ligands for enantioselective catalysis

Chirality plays a fundamental role in biology and chemistry and the precise control of chirality in a catalytic conversion is a key to modern synthesis most prominently seen in the production of pharmaceuticals. In enantioselective metal-based catalysis, access to each product enantiomer is commonly achieved through ligand design with chiral bisphosphines being widely applied as privileged liga...

Geometrically controlled endothelial tubulogenesis in micropatterned gels.

We present a novel approach to control endothelial tubulogenesis by spatially patterning cells within micromolded collagen gels. Endothelial cells cultured within microscale channels that were filled with collagen gel organized into tubes with lumens within 24-48 h of seeding. These tubes extended up to 1 cm in length, and exhibited cell-cell junction formation characteristic of early stage cap...

Towards enantioselective adsorption in surface-confined nanoporous systems.

The adsorption of chiral molecules in surface-confined chiral porous networks shows pronounced selectivity, as a result of complementary host-guest interactions.

Geometrically Controlled 4-Point Interpolatory Schemes

We present several non-linear 4-point interpolatory schemes, derived from the “classical” linear 4-point scheme. These new schemes have variable tension parameter instead of the fixed tension parameter in the linear 4-point scheme. The tension parameter is adapted locally according to the geometry of the control polygon within the 4-point stencil. This allows the schemes to remain local and in ...
