Designing Physical Unclonable Functions From Optically Active Materials
Advanced Materials, EarlyView.Assigning unforgeable “fingerprints” to manufactured goods is a key strategy to fight global counterfeiting. Optical physical unclonable functions (PUFs) are chemically generated random patterns of optically active materials serving as unique authenticators.

Electrochemistry and Spectroscopy of Sulfate and Thiosulfate Complexes of Iron Porphyrins [PDF]
, 2002 The electrochemical and spectroscopic properties of the complex formed by the addition of thiosulfate to ferric porphyrins were examined. The NMR spectrum of the thiosulfate–ferric porphyrin complex was consistent with a high-spin ferric complex, while ...
