NanoMOF‐Based Multilevel Anti‐Counterfeiting by a Combination of Visible and Invisible Photoluminescence and Conductivity

open access: yesAdvanced 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.

Eye Tracking

open access: yes
In this chapter we discuss eye-tracking measures, terms and metrics, hardware and measurement (in section 7.2), their pros and cons (section 7.3), and quality (section 7.4). Concluding remarks can be found in section 7.5.

Fast Neutron Detector Based on Hybrid 2D Perovskite Thin Films

open access: yesAdvanced Functional Materials, EarlyView.
This work presents the direct detection of fast neutrons using flexible hybrid 2D perovskite (PEA2PbBr4) thin‐film detectors. Thanks to their high low‐Z elements content and good charge transport, these materials enable efficient neutron detection. The thin film configuration allowed the operation at low voltage, and offer scalability, flexibility, and

Measuring Deviant Eye Tracking [PDF]

open access: yesSchizophrenia Bulletin, 1981
The two indices that have been proposed for quantifying the accuracy of smooth-following eye movements are shown to be interchangeable. This algebraic fact will permit comparability of values between laboratories only if workers who employ the signal-to-noise ratio (S/N) as their index measure S and N as the total signal and noise power, respectively ...

Efficient Hole Injection From Indium Tin Oxide in Quantum‐Dot Light‐Emitting Diodes

open access: yesAdvanced Functional Materials, EarlyView.
The realization of QLEDs‐based displays remains challenging due to the acidic surface from PEDOT:PSS. Here, an analysis is conducted by examining the degradation mechanism of PEDOT:PSS. By replacing PEDOT:PSS with 2BrCzPA, the formation of strong dipoles at the ITO/2BrCzPA SAM interfaces exhibits excellent hole injection abilities.

Microplate Active Migration Emerging From Light‐Induced Phase Transitions in a Nematic Liquid Crystal

open access: yesAdvanced Functional Materials, EarlyView.
A quasi‐2D, light‐absorbing platelet embedded in a thermotropic nematic liquid crystal is activated with light irradiation. Depending on the light intensity, the platelet induces a localized nematic‐isotropic phase transition that triggers the motion. Using different confinements, the platelet can glide in a 2D regime or tilt and glide in a 3D regime ...
