Previous attempts at making such a gas had failed because it proved impossible to cool molecules with large dipole moments to the sub-milliKelvin temperatures needed to create a quantum gas. But now a ...

We decided to use ladder-type molecules, which are shape-persistent, and they showed a stable set of rigid conformations so that we can achieve stable and robust molecular junction conductance." ...

Super-rotors are fast rotating molecules whose rotational–translational energy transfer is suppressed. Here the authors study the equilibration of super-rotor gases through molecular dynamics ...

Molecules in a gas are more widely dispersed, freely moving around without obstructing one another. In a liquid, however, they rub up against each other, and in a solid they are so packed together ...

An oligosaccharide is a small polymer that typically has three to ten individual sugar molecules. Most naturally occurring oligosaccharides can be found in plants. For example, Raffinose, a ...

In 1962, however, chemists discovered molecules containing xenon and now call these elements noble gases instead. But no-one had ever seen a molecule in space harbouring a noble gas, even though one ...

Liu explains, "For a molecule with multiple conformations, the variation in conductance is very large, sometimes 1,000 times different. We decided to use ladder-type molecules, which are shape ...

Separating gases using a rigid polymer sieve ... However, the transport of larger gas molecules is hindered by the polymer's extreme rigidity so that it acts as an efficient molecular sieve.
