When defects become ‘dynamic’: halide perovskites: a new window on materials?

If defects in materials cost more (energy) than decomposing them, defect densities will be low and thermodynamically controlled, with the right kinetics, as for halide perovskites.

How to quantify isotropic negative thermal expansion: magnitude, range, or both?

Negative thermal expansion (NTE) is the counterintuitive material property of volume contraction on heating. We compare different systems with contrasting mechanisms for isotropic NTE using the metric of NTE capacity.

The living dead – common misconceptions about reversible deactivation radical polymerization

We illustrate common misconceptions and errors when interpreting polymerization data from ‘Living/controlled’ radical polymerization, preferably termed ‘reversible deactivation radical polymerization’ (RDRP). Avoiding the discussed errors leads to better defined materials for soft matter materials applications.
