  • Abundant molecular oxygen was discovered recently in the coma of comet 67P, thought to be of primordial origin. Here, the authors propose a dynamic reaction mechanism for cometary comae, which produces O2directly in single collisions of energetic water ions with oxidized cometary surface analogues.

  • Carbon dioxide can dissociate via different pathways depending on the amount of available energy. Here the authors investigate carbon dioxide collisions with metal substrates and observe a pathway producing molecular oxygen, which might explain the presence of oxygen in abiotic environments.

  • Uniformly distributing nanoparticles on nanofibres can benefit electrocatalysis by increasing surface area, but it is complex. Here the authors use facile, inexpensive, nozzle-free electrospinning to produce dispersed nanoparticles on nanofibres, attaining increased voltage in a commercial-scale fuel cell.
