Fine DNA structure revealed by constant height frequency modulation AFM imaging

Giovanni Dietler, Dusan Vobornik, Andrea Cerreta

Few examples of sub nanometer resolution on biomolecules can be found in literature. In particular, AFM experiments on DNA mostly fail to show the double helical groove periodicity, and so far such a feat was only achieved in liquid. Here we describe a met ...

Chiral Monodentate Trialkylphosphines Based on the Phospholane Architecture

Nicolai Cramer, Tanguy Jean Daniel Saget, Pavel Alexandrovich Donets

The development of efficient chiral monodentate phosphine ligands lags behind that of the bidentate congeners. This holds especially true for highly electron rich chiral phosphine analogues able to replace the ubiquitous tricyclohexylphosphine and tri-tert ...
