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.

Link between the photonic and electronic topological phases in artificial graphene

, 2017
In recent years the study of topological phases of matter has emerged as a very exciting field of research, both in photonics and in electronics. However, up to now the electronic and photonic properties have been regarded as totally independent.

Ash plume properties retrieved from infrared images: a forward and inverse modeling approach

, 2014
We present a coupled fluid-dynamic and electromagnetic model for volcanic ash plumes. In a forward approach, the model is able to simulate the plume dynamics from prescribed input flow conditions and generate the corresponding synthetic thermal infrared (

Combined Studies of  N and NN Scattering and Electromagnetic Form Factor of Nucleon Based on the    Dynamics [PDF]

Progress of Theoretical Physics, 1980
Systematic studies of the pion-nucleon and the nucleon-nucleon scatterings and the iso­ vector part of the nucleon electromagnetic form factor on the basis of pion-pion dynamics are performed by using the twice-subtracted dispersion relation. Starting from the pion-pion amplitude, the l=L=1 and l=L=O helicity amplitudes of the (mH->NN) process can be ...

Plasmonic nanoparticle monomers and dimers: From nano-antennas to chiral metamaterials

, 2011
We review the basic physics behind light interaction with plasmonic nanoparticles. The theoretical foundations of light scattering on one metallic particle (a plasmonic monomer) and two interacting particles (a plasmonic dimer) are systematically ...
