Advanced Optical Materials, EarlyView.For most microscopy measurements the sample is placed on a substrate, which causes symmetry breaking, especially relevant for chiral plasmonic nanostructures. DNA origami mediated X‐shaped AuNR dimers showing high structural purity in solution, exhibit significant diversity in lineshapes and signal intensities for their circular differential scattering

High Fidelity Waveguides Through Vitreous Media Recomposition for Next Generation Photonic Devices
Advanced Optical Materials, EarlyView.A newly designed aluminosilicate glass enables the fabrication of femtosecond laser‐written optical waveguides with ultra‐low propagation losses of −0.020 dB cm−1 at 1310 nm and −0.037 dB cm−1 at 1550 nm. Raman, Brillouin, and electron microscopy analyses reveal the mechanisms behind refractive index modifications, highlighting the role of glass ...

AIChE Journal, Volume 69, Issue 1, January 2023., 2023 Abstract In recent years, the catalyst pellets made of open‐cell metallic foams have been identified as a promising alternative in fixed‐bed reactors. A reliable modeling tool is necessary to investigate the suitability of different foam properties and the shapes of foam pellets.

Advanced Optical Materials, EarlyView.Photochromic compounds are versatile ingredients for the development of Chemical AI. When they are embedded in a tight microenvironment, they become Markov blankets. They are also valuable for processing Boolean and Fuzzy logic. They contribute to neuromorphic engineering in wetware based on opto‐chemical signals exchanged with oscillatory chemical ...

AIChE Journal, Volume 69, Issue 2, February 2023., 2023 Abstract This work develops a model predictive control (MPC) scheme using online learning of recurrent neural network (RNN) models for nonlinear systems switched between multiple operating regions following a prescribed switching schedule. Specifically, an RNN model is initially developed offline to model process dynamics using the historical ...

Advanced Photonics Research, EarlyView.This work demonstrates the use of reactive laser annealing to selectively tune the epsilon‐near‐zero condition of tin‐doped indium oxide patches integrated in silicon waveguides. This postgrowth annealing technique enables flexible control over the optical constants of transparent conducting oxides (TCOs) at critical telecom wavelengths, paving the way
