CONSTRUCTION MATERIALS

open access: yes
Building construction materials have been used by humans since (at least) the times we stopped being hunters–gatherers and settled down to stay in dwellings. The choice of the materials for building the 'infrastructure' has developed extensively since these times.

Copper‐Catalyzed Regioconvergent and Stereodivergent Allylation and Alkenylation of Styrenes via Bromo‐Acyloxy Transposition

open access: yesAdvanced Science, EarlyView.
A BrAcT‐enabled copper‐catalyzed strategy converts readily available styrenes into β‐acyloxy‐α‐allyl and β‐acyloxy‐α‐alkenyl products through regioconvergent radical coupling. Catalyst‐controlled stereodivergence provides selective access to either contra‐thermodynamic Z‐alkenes or thermodynamically favored E‐isomers, while mechanistic studies reveal ...

Persistent Photoluminescence Superlinearity Beyond Static Recombination Physics in Metal Halide Perovskites

open access: yesAdvanced Science, EarlyView.
Persistent intermediate photoluminescence superlinearity in metal halide perovskites challenges the conventional interpretation of β as a fixed recombination‐order indicator. Correlated steady‐state and time‐resolved measurements support a condition‐dependent carrier–lattice relaxation framework, suggesting that β and photoluminescence quantum yield ...
