Photoswitchable Conductive Metal–Organic Frameworks
Advanced Functional Materials, EarlyView.A conductive material where the conductivity can be modulated remotely by irradiation with light is presented. It is based on films of conductive metal–organic framework type Cu3(HHTP)2 with embedded photochromic molecules such as azobenzene, diarylethene, spiropyran, and hexaarylbiimidazole in the pores.

Aspects concerning the circularity and cylindricity deviation of a work piece processed by turning
MATEC Web of Conferences, 2017 All the cutting processes impose certain specifications for the work pieces obtained. In such conditions, the parameters as tolerance, roughness and geometrical deviations must be well known in order to determine the obtained accuracy of the processed ...

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.
