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.

Quantization of surface Dirac states could lead to exotic applications

Scientists have uncovered the first evidence of an unusual quantum phenomenon - the integer quantum Hall effect - in a new type of film, called a 3D topological insulator. In doing this, they demonstrated that 'surface Dirac states' - a particular form of massless electrons - are quantized in these materials, meaning that they only take on certain discrete values.
