Solution structure of a DNA double helix with consecutive metal-mediated base pairs
The incorporation of non-natural base pairs into double-stranded DNA, especially those mediated by metal–ligand interactions, offers new opportunities for synthetic DNA materials. The structural implications of such modifications will help guide developments in this area, and a solution structure of a B-type DNA duplex containing consecutive metal-mediated base pairs has now been elucidated.

Dianionic species with a bond consisting of two pentacoordinated silicon atoms
Silicon, like carbon, favours a four-coordinate geometry and this underpins the frameworks of the wide range of inorganic and organosilicon compounds, from silicate minerals to polysilanes. Although some pentavalent silicon compounds have already been reported, this work presents the first example where two five-coordinate silicon atoms are bonded to each other.

Random two-dimensional string networks based on divergent coordination assembly
The bulk properties of materials that lack long-range order have been widely studied, but their local structures remain difficult to elucidate. Now, using scanning tunnelling microscopy, researchers have been able to look more closely at the structural motifs of robust, two-dimensional glassy networks assembled through metal–ligand interactions.

Towards quantum chemistry on a quantum computer
Precise calculations of molecular properties from first-principles set great problems for large systems because their conventional computational cost increases exponentially with size. Quantum computing offers an alternative, and here the H2 potential energy curve is calculated using the latest photonic quantum computer technology.

Analysis of the reactivity and selectivity of fullerene dimerization reactions at the atomic level
Well-resolved images of small molecules and their motions can be obtained with high-resolution transmission electron microscopy. It has now been shown that this technique can also be used to visualize individual chemical reactions involving the dimerization of fullerenes and metallo-fullerenes trapped inside carbon nanotubes by monitoring how the positions of their atoms change over time.

Shaping enzyme inhibitors
Small-molecule enzyme-inhibitors often display insufficient affinity and selectivity for their targets causing unwanted side effects when used as drugs. Molecularly imprinted polymers prepared using the enzyme as a template could offer a solution.

Producing 'perfect' particles
Synthetic procedures for making nanoparticles often result in samples that contain a range of different particle sizes. By using hollow self-assembled metal–organic spheres as templates, however, it is possible to make silica nanoparticles with uniform shapes and sizes in a precisely controlled fashion.
