InternationalAtom size – not electronegativity – determines polymer stability
The stability of hydrogen-bonded amide polymers depends on which atom replaces the oxygen in the amide.

InternationalMethane hide-and-seek makes methanol
You can ‘hide’ methane in a cavity of an iron catalyst decorated with an organic structure and thus selectively oxidise it to methanol.

InternationalAlgae autocatalyse biofuel production
The alga Chlorella variabilis can convert medium fatty acids into petrol-like hydrocarbons. However, commercial application is still a long way off.

InternationalPast the von Neumann bottleneck in thousands of steps
Miniaturisation and integration into existing electronics are key to the large-scale application of memristors, programmable resistors that combine memory and processor in computers. Researchers in Groningen and the US are now developing methods to get more out of their memristors.
