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.

Modulating Two‐Photon Absorption in a Pyrene‐Based MOF Series: An In‐Depth Investigation of Structure–Property Relationships

Advanced Functional Materials, EarlyView.
This study investigates H4TBAPy‐based metal–organic frameworks (MOFs) ‐ NU‐1000, NU‐901, SrTBAPy, and BaTBAPy ‐ for multiphoton absorption (MPA) performance. It observes topology‐dependent variations in the 2PA cross‐section, with BaTBAPy exhibiting the highest activity.

Near‐Infrared Emitting Lanthanide Catecholate Giant Single Crystals – Morphology Control and Photon Down‐Conversion

Advanced Functional Materials, EarlyView.
Controlled syntheses of lanthanide coordination polymers based on the dihydroxybenzoquinone (DHBQ) organic linker afforded large single crystals of Ln‐DHBQ CPs (Ln = Yb, Nd). A novel structural variant of Yb‐DHBQ is identified by means of single crystal diffraction analysis.

Self-excited vibrations of optical microresonators

Electronics Letters, 1988
Microresonators in the form of metal coated silicon dioxide strips have been driven into resonant vibration by the application of unmodulated fibre-guided light. The experiments carried out to observe this phenomenon are described, their results presented and discussed, and the implications for multiplexing microresonators sensors in fibre-optic ...

Dynamic absorber for self-excred system with distributed parameters (vibrating string)

Vietnam Journal of Mechanics, 1985
The dynamic absorber may be used to damp the self - excited vibration or the string. The friction mechanism of absorber (λ) has decisive influence on the amplitude of self-exerted vibration of the string. For the strong dynamic absorber the increasing
