Bij koude botsingen verliest het dipoolmoment de vermeende permanente status, zo laten theoretisch chemici en experimenteel fysici van de Radboud Universiteit zien in Nature Chemistry. Dat biedt geheel nieuwe mogelijkheden om een chemisch proces volledig te controleren. Het vroeg wel wat creativiteit om het benodigde ‘onmogelijke’ experiment toch te realiseren.

Physics World: Nuclear clocks finally see the light
Two independent teams have realized the first clocks based on transitions within atomic nuclei. The new nuclear clocks represent the culmination of more than 20 years of research and could become vital tools in precision tests of fundamental physics.
Physics World: Collisions between dipolar molecules switch off at low energies
Researchers in the Netherlands have shown that they can turn off the dipole moment of molecules that are normally polar, drastically altering the molecules’ behaviour in low-energy collisions. The discovery – which was only possible after the team cleared a major experimental hurdle – has implications for ultracold chemistry and could also lead to a better understanding of polarity, with benefits for quantum simulation and computation.
