Hybrid Electroluminescence Device for On‐Demand Single Photon Generation at Room Temperature

open access: yesAdvanced Optical Materials, EarlyView.
New type of electroluminescent device based on hBN nanocrystals deposited on a GaN laser diode displays electrically driven emission of single photons at room temperature. Low g2(0) autocorrelation function values are achieved of < 0.2 for continuous driving and < 0.4 for on‐demand single‐photon emission.

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

open access: yesAdvanced 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 ...

Effective and Practical Stereoselective Synthesis of Nutlins Precursors by Immobilization of Privileged Chiral Mono‐Amidine Catalyst

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
Abstract A strategy for the immobilization of Johnston's Mono(AMidine) catalyst (MAM) onto polystyrene, silica and hybrid silica‐polystyrene nanoparticles is presented. The catalyst activity was evaluated in the stereoselective aza‐Henry reaction leading to the pivotal β‐amino nitroalkane precursors of the anti‐cancer agents Nutlins (with Nutlin‐3a as ...

Gram‐Scale Photocatalysis with a Stable and Recyclable Chromium(III) Photocatalyst in Acetonitrile and in Water

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
Abstract The use of stable photosensitizers made on a multigram‐scale from cheap and available starting materials offers an extraordinary opportunity to translate small‐scale proof‐of‐concept photoreactions to widespread applications in non‐specialized laboratories, thereby promoting the implementation of light‐driven syntheses.

SyMO: A Hybrid Approach for Multi‐Objective Optimization of Crystal Growth Processes

open access: yesAdvanced Theory and Simulations, EarlyView.
The hybrid SyMO (Symbolic regression Multi‐objective Optimization) framework combines Computational Fluid Dynamics (CFD), machine learning, and mathematical optimization techniques to investigate the effects of various process parameters, furnace geometries, and radiation shield material properties on key crystal quality metrics in Czochralski silicon (
