Online monitoring of thermoset post-curing by dynamic mechanical thermal analysis DMTA
Polymer Testing, 2009 Abstract Thermosetting moulding compounds are synthetic materials which can be easily formed in the molten state and achieve high temperature stability due to a cross-linking process which takes place during manufacture. To ensure thermal and mechanical properties, post-curing of moulded phenolic resin components is necessary for high quality ...

Dipolar Filtered magic-sandwich-echoes as a tool for probing molecular motions using time domain NMR
, 2017 We present a simple $^1$H NMR approach for characterizing intermediate to fast regime molecular motions using $^1$H time-domain NMR at low magnetic field. The method is based on a Goldmann Shen dipolar filter (DF) followed by a Mixed Magic Sandwich Echo (
