Photoredox cooperative N-heterocyclic carbene/palladium-catalysed alkylacylation of alkenes
Nature Communications, 2022 Three-component carboacylation of simple alkenes often requires directing groups and strained substrates. Here, the authors report a photoredox N-heteroyclic carbene/Pd-catalysed alkylacylation of alkenes with aldehydes and unactivated alkyl halides ...

Molecular Recognition in a Thermoplastic Elastomer
Journal of the American Chemical Society, 2005 Selective incorporation of bisurea guests in thermoplastic elastomers with poly(tetrahydrofuran) soft blocks and bisurea containing hard blocks is observed when the distances between the urea groups of host and guest match. The incorporation leads to significant modulation of mechanical properties.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...
