Demo 15-18 Sublimation of CO 2
, 2001 This experiment illustrates the enormous change in the volume of a material as it changes state from a gas to a liquid or a solid. A carbon dioxide balloon collapses entirely when it is immersed in liquid nitrogen, because the liquid nitrogen cools the ...

Angewandte Chemie, EarlyView.Dibenzo[b,d]selenophene (DBSe) π‐core fusion enables rapid triplet–singlet interconversion while preserving the narrowband emission features of multi‐resonance thermally activated delayed fluorescence (MR‐TADF) luminogens. Combined with peripheral donor engineering, this strategy enables systematic emission tuning from green to red, leading to highly ...
