Spectrophotometric determination of antioxidant activity

Redox Report, 1996
The spectrophotometric technique for total antioxidant activity (TAA)(1,2) measures the relative abilities of antioxidants to scavenge the 2,2'-azino-bis(3-ethylbenz-thiazoline-6-sulfonic acid) (ABTS) radical cation (ABTS(•+)) in comparison with the antioxidant potency of standard amounts of Trolox, the water-soluble vitamin E analogue.

Tailoring the Properties of Functional Materials With N‐Oxides

Advanced Functional Materials, EarlyView.
The properties of materials bearing N‐oxide groups are often dominated by the polar N+─O− bond. It provides hydrophilicity, selective ion‐binding, electric conductivity, or antifouling properties. Many of the underlying mechanisms have only recently been discovered, and the interest in N‐oxide materials is rapidly growing.
