Bright Circularly Polarized Electrochemiluminescence from Heterobinuclear IrIII–AuI Enantiomers
Angewandte Chemie, Volume 138, Issue 1, 2 January 2026.Efficient and bright circularly polarized electrochemiluminescence (CP‐ECL) is achieved in a class of enantiopure hetobinuclear iridium(III)–gold(I) complexes owing to the combination of high ECL efficiency with stability, good emission dissymmetry factor and high brightness, thus paving the way to the next‐generation of bright CP‐ECL probes.

Allocative efficiency and the productivity slowdown
Canadian Journal of Economics/Revue canadienne d'économique, EarlyView.Abstract This paper evaluates the contribution of cross‐sector allocative efficiency to the productivity slowdown in the US during the 1970s and 2000s. We extend the framework of Oberfield (2013) to derive sufficient statistics for allocative efficiency and decompose aggregate productivity growth in a multisector economy.

Aggregate productivity effect of labour and capital market distortions in Canada
Canadian Journal of Economics/Revue canadienne d'économique, EarlyView.Abstract How efficiently are workers, investment capital, and production distributed across firms in Canada? And how have they varied over time, across regions, and between sectors? To answer these questions, we present novel measures of the degree of resource misallocation over time and space using uniquely detailed firm‐level data (T2‐LEAP) between ...

The results showed that participants tended to rate high‐shine hair more favourably than lower‐shine hair. When combining shine with alignment and volume, straight‐aligned hair with high shine and low volume was generally perceived as more ...
