Photoswitchable Conductive Metal–Organic Frameworks

Advanced Functional Materials, EarlyView.
A conductive material where the conductivity can be modulated remotely by irradiation with light is presented. It is based on films of conductive metal–organic framework type Cu3(HHTP)2 with embedded photochromic molecules such as azobenzene, diarylethene, spiropyran, and hexaarylbiimidazole in the pores.

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

Advanced 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.

Small, Smart, Powerful?

, 2021
“Size matters in international relations,” (Steinsson /Thorhallsson 2017: 1), but does size still matter in the digital age, and in the cyber domain? Scholars have long believed that larger states are better equipped for state competition due the size of their populations, economies, and militaries based on a respective size/power calculus.

Printed Integrated Logic Circuits Based on Chitosan‐Gated Organic Transistors for Future Edible Systems

Advanced Functional Materials, EarlyView.
Edible electronics needs integrated logic circuits for computation and control. This work presents a potentially edible printed chitosan‐gated transistor with a design optimized for integration in circuits. Its implementation in integrated logic gates and circuits operating at low voltage (0.7 V) is demonstrated, as well as the compatibility with an ...

Seamless islanding-aware frequency constrained microgrid scheduling

International Journal of Electrical Power & Energy Systems
The frequency security of low-inertia microgrids (MGs) is a critical concern following unintentional islanding events (UIEs). To tackle this challenge, this paper proposes a seamless islanding-aware frequency-constrained MG scheduling model.
