Angewandte Chemie International Edition, Accepted Article.The synthesis of polarized N‐heterocyclic olefins (NHOs) based on an imidazo[1,5‐a]pyridine scaffold is presented. In contrast to regular NHOs the unique bicyclic heterocyclic core allows the incorporation of various substituents in close proximity to the highly polarized exocyclic C–C bond.

Macromolecular Chemistry and Physics, Volume 224, Issue 1, January 2023., 2023 Four different spiropyrans with consistently varying substitution patterns are incorporated into the middle of poly(ε‐caprolactone) used for tensile testing with in‐situ UV–vis spectroscopy. The influence of combined electronic and steric effects on the force‐induced spiropyran–merocyanine transition is investigated theoretically and experimentally by ...

Pulse‐Level Quantum Robust Control with Diffusion‐Based Reinforcement Learning
Advanced Physics Research, EarlyView.This paper proposes a diffusion‐based reinforcement learning method for pulse‐level quantum robust control (PQC‐DBRL) to enhance the robustness of pulse‐level quantum gate control. When evaluated across different Hamiltonian variations, PQC‐DBRL shows a smaller fidelity variance compared to GRAPE, indicating higher robustness against system parameter ...

Orientation‐Dependent Upper Critical Magnetic Field and Density of State for Uranium Ditelluride
Advanced Physics Research, EarlyView.This study investigates the orientation‐dependent upper critical magnetic field (HC2) and the density of states (DOS) in the unconventional superconductor UTe2. These results reveal an anisotropic HC2, with distinct critical fields along different crystallographic axes, highlighting the role of electronic correlations and spin‐triplet pairing.

Astronomische Nachrichten, EarlyView.ABSTRACT We investigate the effects of a minimal measurable length on neutron stars, within the quantum hadrodynamics (QHD‐I) model modified by the Generalized Uncertainty Principle (GUP). Working in a deformed Poisson algebra framework, we incorporate GUP effects via a time‐invariant transformation of the phase space volume, effectively reducing the ...

Host‐guest tuning of the CO2 reduction activity of an iron porphyrin cage
Natural Sciences, Volume 3, Issue 1, January 2023., 2023 An iron porphyrin cage can catalyze CO2 electroreduction to CO with a large selectivity. The catalytic properties can be further improved by tuning the internal electrostatic potential of the cage by hosting the potassium ions in the crown‐ether‐like side walls.
