High‐Performance Recyclable Polyester Elastomers Through Transient Strain‐Stiffening
Advanced Materials, EarlyView.Transient strain‐crystallization simultaneously strengthens and toughens block polyester elastomers while conserving recyclability. Using controlled polymerization catalysis and commercial monomers, block polyester elastomers outperform current commercial elastomers, entering a new region of tensile mechanical property space.

PPh3/Isocyanide and N2/Isocyanide Exchange: Pathways to Isolable Alkali Metal Keteniminyl Anions
Angewandte Chemie, EarlyView.The synthesis of isolable keteniminyl anions through substitution of the phosphine ligand in metalated ylides or the N₂ ligand in diazomethanides with isocyanides is reported. The anions feature a bent geometry, with the angle decreasing with increasing donor ability of the nitrogen substituent, and exhibit broad applicability in the formation of ...

Molecules with a peptide link in protostellar shocks: a comprehensive study of L1157 [PDF]
, 2014 Interstellar molecules with a peptide link -NH-C(=O)-, like formamide (NH$_2$CHO), acetamide (NH$_2$COCH$_3$) and isocyanic acid (HNCO) are particularly interesting for their potential role in pre-biotic chemistry. We have studied their emission in the protostellar shock regions L1157-B1 and L1157-B2, with the IRAM 30m telescope, as part of the ASAI ...

Advanced Materials, EarlyView.In nitrogen vacancies‐rich nickel nitride (Ni3N‐VN), a local microenvironment of nitrogen vacancies and adjacent Ni sites is formed. The electron‐rich Ni‐sites can be converted to NiOOH at a lower potential, and urea adsorption on the electron‐deficient nitrogen vacancy region is conducive to its partial dissociation, conceiving to efficient urea ...
