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.

Flexible three‐dimensional printed antenna substrates

The Journal of Engineering, 2015
Flexible heterogeneous substrates have been constructed, using three‐dimensional printing in a single process, by introducing air‐filled slots. These substrates have been used to substantially reduce the substrate losses for a flexible microstrip patch antenna causing an increase in its radiation efficiency.

Three-Dimensional (3D) Printing in Orthopedics Education

Journal of Long-Term Effects of Medical Implants, 2020
Three-dimensional (3D) printing is a newly established concept in orthopedics compared with other industries. Surgical applications of 3D printing and tissue engineering have been investigated since the early 2000s, almost two decades after Charles Hull had patented the first device currently in use for additive manufacturing, also known as rapid ...
