  • Roaming dynamics have been shown to be important in unimolecular decompositions, but the relevance to bimolecular reactions has been less clear. Here, the authors study radical addition/elimination reactions and implicate a roaming transition state in a bimolecular reaction.

  • Intersystem crossing (ISC) is a radiationless process that is important in many photophysical systems. It has now been observed to take place in the exit channel for the reaction of ground-state atomic oxygen with alkylamines.

  • ‘Roaming’ is a recently discovered reaction dynamics phenomenon in which a molecule undergoes frustrated dissociation to radicals, followed by an intramolecular abstraction reaction. An imaging study, with associated high-level ab initio calculations, has now shown that ‘roaming-mediated isomerization’ plays a key role in the photodissociation of nitrobenzene.

  • Scattering experiments in which two beams nearly co-propagate allow broadly tunable collision energies and can enable cold collisions. Now, such experiments have been combined with the preparation of NO molecules using stimulated emission to generate highly vibrationally excited states for state-to-state scattering studies, testing the theoretical gold standard in a regime not found in nature.

  • One of the UN’s 17 sustainable development goals (SDGs), SDG 7, is to “ensure access to affordable, reliable, sustainable and modern energy for all.” This goal addresses the need for environmental sustainability while highlighting energy’s vital role in promoting social and economic justice. It calls for sustainable, affordable, modern, and reliable energy usage for the health and well-being of society while mitigating climate change. Here, we briefly review available literature and data to examine how renewable energy, food security, and sustainability are interconnected in Arctic countries and regions, and how these regions can “ensure access to affordable, reliable, sustainable and modern energy for all” and progress towards achieving food self-sufficiency by integrating renewable energy sources into food production systems. We analyze several case studies to draw conclusions on how Arctic communities can become resilient, sustainable, and economically prosperous by promoting local food production while preserving cultural practices.
