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.

Advanced Functional Materials, EarlyView.This study demonstrates an alternative method of creating charge‐stable negatively charged nitrogen vacancy (NV−) centers close to the diamond surface without high‐temperature annealing. By illuminating nitrogen‐implanted regions with a continuous‐wave 405 nm laser, NV− centers are induced, exhibiting electron spin coherence properties suitable for ...

A scheme to alter the resonant frequency of the microstrip patch antenna [PDF]
Simple schemes are presented for altering the resonant frequency of a rectangular patch antenna without the need to change its size. In particular, by placing a perturbance below the patch it is shown that as much as 20 percent increase and 30 percent ...
