Information Hiding in the Join Calculus [PDF]

open access: yes, 2007
We aim to provide information hiding support in concurrent object-oriented programming languages. We study this issue both at the object level and the class level, in the context of an object-oriented extension of Join-- a process calculus in the tradition of the π-calculus.

NanoMOF‐Based Multilevel Anti‐Counterfeiting by a Combination of Visible and Invisible Photoluminescence and Conductivity

open access: yesAdvanced Functional Materials, EarlyView.
This study presents novel anti‐counterfeiting tags with multilevel security features that utilize additional disguise features. They combine luminescent nanosized Ln‐MOFs with conductive polymers to multifunctional mixed‐matrix membranes and powder composites. The materials exhibit visible/NIR emission and matrix‐based conductivity even as black bodies.
