Design and Experiments of Electromagnetic Heating Forming Technology

IEEE Access, 2019
Electromagnetic forming (EMF) has been widely applied in industries. However, it's still hard to form thick or hard metal work pieces due to the limitation of its system power. Moreover, increasing the input voltage or capacitors may cause the problem of

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.
