Bayesian Optimization Guiding the Experimental Mapping of the Pareto Front of Mechanical and Flame‐Retardant Properties in Polyamide Nanocomposites

Advanced Intelligent Discovery, EarlyView.
Bayesian optimization enabled the design of PA56 system with just 8 wt% additives, achieving limiting oxygen index 30.5%, tensile strength 80.9 MPa, and UL‐94 V‐0 rating. Without prior knowledge, the algorithm uncovered synergistic effects between aluminum diethyl‐phosphinate and nanoclay.

Aminal‐linked Covalent Organic Frameworks for Light Energy Upconversion

Angewandte Chemie, EarlyView.
Aminal‐linked covalent organic frameworks incorporating anthracene units are introduced as solid‐state platforms for triplet–triplet annihilation upconversion. The crystalline materials retain chromophore electronic properties and exhibit fluorescence quantum yields of up to 40%.

One‐Dimensional Polycyclic Aromatic Hydrocarbons Incorporating Multiple Dithiafulvene Units—Novel Multi‐Redox and Electrochromic Systems

Angewandte Chemie, EarlyView.
Planar polycyclic aromatic hydrocarbons (PAHs) incorporating three or four dithiafulvene (DTF) units were synthesized via Horner–Wadsworth–Emmons reactions to create large π‐conjugated redox‐active frameworks. These molecules display strong intermolecular associations and distinct odd–even redox behavior, enabling formation of mixed‐valence and radical‐

Artificial Intelligence in Autonomous Mobile Robot Navigation: From Classical Approaches to Intelligent Adaptation

Advanced Intelligent Systems, EarlyView.
Artificial intelligence (AI) is reshaping autonomous mobile robot navigation beyond classical pipelines. This review analyzes how AI techniques are integrated into core navigation tasks, including path planning and control, localization and mapping, perception, and context‐aware decision‐making. Learning‐based, probabilistic, and soft‐computing methods

Extended Fused Carbazole‐BODIPY, High Brightness NIR Organic Dyes

Angewandte Chemie, EarlyView.
Highly fused boron‐dipyrromethene (BODIPY) with a strong donor group has been synthesized, and their photophysical behaviors fully characterized. They exhibit outstanding brightness for fluorophores emitting in the NIR region. Water‐soluble nanoparticles filled with one of these dyes demonstrate high efficiency as the NIR II visualization agent ...

Scalp electroacupuncture targeting trigeminal nerve activation alleviates post‐traumatic stress disorder–induced depression and neuroinflammation in mice

Animal Models and Experimental Medicine, EarlyView.
Scalp electroacupuncture (SA) through activation of the trigeminal pathway exerts anti‐inflammatory, antidepressant, and anxiolytic effects in an animal model of post‐traumatic stress disorder induced by single prolonged stress. This suggests that SA is involved in neuroinflammation and changes in brain‐derived neurotrophic factor protein through the ...
