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.

Effectiveness of Sodium Azide Alone Compared to Sodium Azide in Combination with Methyl Nitrosurea for Rice Mutagenesis

Plant Breeding and Biotechnology, 2016
Rice seeds of the temperate japonica cultivar Kitaake were mutagenized with sodium azide alone and in combination with methyl nitrosourea. Using the reduced representation sequencing method Restriction Enzyme Sequence Comparative Analysis (RESCAN), the mutation densities, types and local sequence context were determined in the resulting M2 generation ...

Self‐Trapped Excitons Activate Pseudo‐Inert Basal Planes of 2D Organic Semiconductors for Improved Photocatalysis

Advanced Materials, EarlyView.
2D organic semiconductors are widely believed to have uniformly active surfaces. This study reveals that their basal planes can be pseudo‐inert due to anisotropic exciton migration. By inducing exciton self‐trapping through dimensional reduction, these inert planes are activated, boosting hydrogen peroxide production by over 350%. The work uncovers key
