New method to engineer surfaces along multiple directions in a nanowire

This new technique, termed coaxial lithography (COAL), offers a combination of radial and longitudinal degrees of compositional freedom within the nanowire. Synthetic control over the radial dimension combined with the possibility of selectively deleting features used to build the nanowires significantly expands the range of architectures that can be synthesized using COAL.

Making carboxyl(ate) friends

When it comes to supramolecular chemistry, the carboxylic acid group - and its conjugate carboxylate base - is one of the chemist's most flexible friends. In pairs, they act as supramolecular synthons from which more complicated structures might be built but also offer up complex hydrogen bond connectivity.
