Ultrasonic signals at frequencies below 1 MHz have been used for the NDE of thick polymer samples. Coded signals such as chirps and bipolar Golay codes, together with pulse compression and signal processing, have been used to penetrate into thick sections of attenuating polypropylene riser stiffener material, using piezocomposite transducers to...

Synthesis and characterization of a new biobased poly(urethane-ester) from ricinoleic acid and its...

This work presents a new biobased poly(urethane-ester) synthesized from ricinoleic acid (RA), 1,6-diisocyanatehexane, and glycerol through bulk polymerization. RA-modified magnetic iron oxide nanoparticles, previously obtained through coprecipitation technique, were introduced in situ to produce a magnetic nanocomposite. DSC analyses revealed that...
