After air-drying, the residual solvent in PA66 was removed in a vacuum dryer at 50 °C for 3 h. The concentration of TTBNB in the PA66 matrix was controlled at 3 wt%. The thickness of the film was ca. 500 μm.

WebSpin-trapping is a chemical reaction that provides an approach to help overcome this problem. Spin traps are compounds that react covalently with highly transient free radicals to form relatively stable, persistent spin adducts that also possess paramagnetic resonance spectra detectable by EPR spectroscopy. ... Other agents of interest may also ... WebMay 1, 2004 · Abstract. Electron paramagnetic resonance (EPR) spin trapping was originally developed to aid the detection of low-molecular-mass radicals formed in chemical systems. It has subsequently found widespread use in biology and medicine for the direct detection of radical species formed during oxidative stress and via enzymatic reactions. WebNov 1, 2003 · It was established that in short-term studies (up to 100 s) DMPO was the superior spin trapping agent, but for reaction times longer than 100 s the other two spin traps were more advantageous. The second order rate constants for the spin trapping reaction were found to be DMPO (2.4 M(-1)s(-1)), DEPMPO (0.53 M(-1)s(-1)), and BMPO … shy bishop with a flush in a nervous state
