Dual‐Mode Thio‐MacMillan Organocatalysts: Stereoselective Diels–Alder Reactions or Sacrificial Self‐Cyclization to N‐Bridged Bicyclic Lactams

Chemistry – A European Journal, EarlyView.
The study of the Diels–Alder reaction of cinnamaldehyde and cyclopentadiene, catalyzed by chiral imidazolidine‐4‐thiones, led to the discovery of a highly regio‐ and stereoselective Michael‐addition and consecutive ring closure. Here, the imidazolidine‐4‐thione not only catalytically activates cinnamaldehyde but also participates as the nucleophile to ...

Highly Conductive, Flexible, and Recyclable Phase Change Thermal Management Film

EcoEnergy, EarlyView.
This Research Highlight focuses on the work that fabricates flexible, recyclable and leak‐proof phase change film via a nacre‐inspired brick‐and‐mortar strategy of shear‐induced orientation followed by hot pressing, where SEBS/POE dual physical crosslinking network and ordered graphite nanoplatelets enhance thermal conductivity, recyclability, and ...

Synthetic Engineering of Manganese Oxide–Carbon Nanocomposites for Maximized Metal Utilization in Supercapacitors

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A one‐pot metal–ammonia synthesis enables uniform Mn2O3 nanoparticle deposition on activated carbon, yielding composites with excellent electrochemical performance in supercapacitors. The method maximizes manganese utilization, eliminates toxic solvents, and achieves 34% of the theoretical maximum capacitance, significantly outperforming existing Mn–C ...
