Aerosol Jet Printing of Superhydrophobic Surfaces

Advanced Materials Technologies, EarlyView.
A novel method for creating spatially programmable superhydrophobic surfaces using an aerosol jet printer is presented. This technique allows precise deposition of micrometer‐sized polymer solution droplets onto a substrate, with control over surface morphology, microstructure, and wettability through solvent evaporation modulation.

Transforming Room Acoustics with Causality‐Driven Dual‐Function Passive Metamaterials

Advanced Materials Technologies, EarlyView.
This work presents an dual acoustic metamaterial for rooms that achieves excellent broadband performance for both sound absorption and sound diffusion. This is done by using causality formulations linking the absorption of the passive system to its volume, yielding an optimal surface area ratio required for excellent sound absorption and while ...

The Role of Theoretical Calculations for INVEST Systems: Complementarity Between Theory and Experiments and Rationalization of the Results

Advanced Optical Materials, EarlyView.
Theoretical lessons are key for molecules presenting an inverted singlet‐triplet excited state (e.g. S1 and T1) energy difference. This perspective provides a snapshot of the role played by calculations in last years, not only to anticipate experimental findings but also for driving high‐throughput virtual screenings, as well as the main challenge to ...

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 ...

Chemical AI in the Limelight: The Contribution of Photochromic Materials and Oscillatory Chemical Reactions

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 ...
