Angewandte Chemie, EarlyView.Spontaneously aligned, long‐range hexagonal columnar ordering is obtained in phase‐separated dynamic covalent networks by combining discrete siloxanes and dynamic acylsemicarbazide bonds. The ordered network shows improved (thermo)mechanical properties and creep resistance compared to the disordered network.

Biological Monitoring for Isocyanates [PDF]
The Annals of Occupational Hygiene, 2007 Isocyanates are reactive chemicals and thousands of workers may be exposed to them during their manufacture and use in a wide range of products. They are classed as sensitizers and are a major cause of occupational asthma in the UK. Workplace exposure limits are low and control of exposure often depends on personal respiratory protection.

Nickel-Catalyzed Cycloaddition of Alkynes and Isocyanates [PDF]
, 2016 A mild and general route for preparing 2-pyridones from isocyanates and diynes is described. Ni imidazolyidene complexes were used to mediate cyclizations between both internal and terminal diynes with aryl and alkyl isocyanates.
