Full‐Domain 3D Digital Twin for Comprehensive Analysis and Validation of Standing Surface Acoustic Wave Generation on LiNbO3 Substrate

Advanced Materials Technologies, EarlyView.
A full‐domain 3D digital twin of a standing surface acoustic wave (SSAW) device on 128° YX LiNbO3 is developed and experimentally validated. The predictive power of the model is confirmed by electrical characterisation and laser Doppler vibrometry measurements, which show excellent agreement with simulations.

Disrupting J‐Aggregation in Triazatruxene Dimers to Develop Responsive Luminescent Inks for Anti‐Counterfeiting Applications

Advanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
This study investigates the stimulus‐responsive behavior of trialkylated triazatruxene dimers for third‐generation luminescent security inks. In particular, the derivative with flexible dodecyl chains displays high‐contrast, reversible color changes upon heating or shear, driven by liquid crystalline phase transitions and involving J ...

The q-harmonic oscillators, q-coherent states and the q-symplecton [PDF]

The recently introduced notion of a quantum group is discussed conceptually and then related to deformed harmonic oscillators ('q-harmonic oscillators').

Unveiling Ultrafast Spin‐Valley Dynamics and Phonon‐Mediated Charge Transfer in MoSe2/WSe2 Heterostructures

Advanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
This study reveals the potential to manipulate spin‐valley polarization dynamics in MoSe2/WSe2 heterostructures by quantifying different scattering processes following selective photoexcitation. The results show that these heterostructures enable ultrafast valley‐selective charge transfer, with phonon scattering playing a significant role in the ...

Current-Mode Quadrature Oscillator Simple Designs

Journal of Low Power Electronics and Applications
Simple designs of current-mode quadrature oscillators are presented in this work. The main achievement, with regards to the literature, is the minimization of the required transistor count accomplished by the utilization of a suitable lossless ...
