Rhodium‐Catalyzed Intermolecular Arylative [2 + 2 + 1] Annulation–Oxidation to Produce Electron‐Deficient Azulene‐Embedded Polycyclic Aromatic Hydrocarbons

open access: yesAngewandte Chemie, EarlyView.
The synthesis of electron‐deficient azulene‐embedded polycyclic aromatic hydrocarbons has been achieved by the rhodium‐catalyzed intermolecular arylative [2 + 2 + 1] annulation of teraryl diynes with dialkyl acetylenedicarboxylates followed by oxidation at room temperature.

Bulk and Surface Reactivity of LiNi0.5Mn1.5O4 in Contact with (Acidic) Water

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
The comprehensive investigation of the influence of (acidic) water on LiNi0.5Mn1.5O4 as cobalt‐free lithium‐ion battery cathode material reveals that such treatment particularly affects a very thin layer at the particle surface, while the bulk material remains unaffected.

Transient Supramolecular Polymers by pH‐Gated Conformational Control of a Self‐Assembling Cyclodextrin

open access: yesAngewandte Chemie, EarlyView.
A metastable cyclodextrin monomer can form kinetically trapped supramolecular polymer at low pH. Raising the pH triggers gradual depolymerization into the self‐included monomer with a rate that can be preset by tuning the pH value. The pH‐dependence is directly associated with the rigidity of the cyclodextrin bridge, which is modulated by protonation ...

Nuclear Quantum Confinement Enables Robust Deuterium Bonds for Highly Reversible Aluminum Anodes

open access: yesAngewandte Chemie, EarlyView.
Quantum confinement by leveraging D as a quantum bridge is engineered to tailor stronger intra‐ and intermolecular D‐bonds, effectively suppressing water reactivity and achieving exceptional HER inhibition. The induced Al3+ solvation structures further inhibit the decomposition of water at the interface and improve Al redox reversibility.

Artificial Intelligence‐Assisted Target Design for High‐Intensity Laser‐Driven Neutron Sources

open access: yesAdvanced Intelligent Systems, EarlyView.
This study presents an artificial intelligence (AI)‐assisted target design that combines particle‐in‐cell simulations with gradient ascent algorithm to optimize laser‐driven neutron sources. By enhancing the sheath electric field, the optimized structure increases neutron yield by a factor of 4,000.

Chemical Bond Covalency in Superionic Halide Solid‐State Electrolytes

open access: yesAngewandte Chemie, EarlyView.
Achieving high conductivity in halide solid‐state electrolytes requires understanding key factors for ionic diffusion. This study provides direct evidence that metal‐halide covalent bonding controls superionic transitions and enhances Li+ mobility. Tailoring covalency through composition, demonstrated via in situ studies and simulations on bromide ...
