Click'n ROPISA: One‐Pot Synthesis of Ultrabright Fluorescent Nanoparticles Made of Polypeptides

open access: yesAngewandte Chemie, EarlyView.
Self‐assembly and fluorophore conjugation proceed rapidly in a one‐pot “Click'n ROPISA” process, yielding intensely fluorescent polypeptide nanoparticles with tunable visible emission. High dye loading enables efficient energy transfer and single‐particle visualization, while the straightforward synthesis provides versatile access to bright ...

Evolution of Physical Intelligence Across Scales

open access: yesAdvanced Intelligent Discovery, EarlyView.
By following the evolution of physical intelligence across scales, this article shows how intelligence arises from materials, structures, physical interactions, and collectives. It establishes physical intelligence as the evolutionary foundation upon which embodied intelligence is built.

Activating Triplet Excitons in COFs via Layer‐Bridging Co Single Atoms for Photocatalytic H2O2 Production and Tandem C─N Coupling

open access: yesAngewandte Chemie, EarlyView.
This work demonstrates a layer‐bridging coordination strategy of Co single atoms in COFs that promotes the formation and utilization of triplet excited states. The introduction of Co single atoms induces pronounced energy‐level splitting and enhanced spin–orbit coupling, facilitating the generation of 1O2 and O2•– for efficient photocatalytic H2O2 ...

On the Stokes number and characterization of aerosol deposition in the respiratory airways

open access: yes, 2015
Aerosol deposition in the respiratory airways has traditionally been examined in terms of the Stokes number based on the reference flow timescale. This choice leads to large scatter in deposition efficiency when plotted against the reference Stokes number because the velocity and length scales experienced by advected particles deviate considerably from

Overcoming the Nyquist Limit in Molecular Hyperspectral Imaging by Reinforcement Learning

open access: yesAdvanced Intelligent Discovery, EarlyView.
Explorative spectral acquisition guide automatically selects informative spectral bands to optimize downstream tasks, outperforming full‐spectrum acquisition. The selected hyperspectral data are used for tasks such as unmixing and segmentation. BandOptiNet encodes selection states and outputs optimal bands to guide spectral acquisition. Recent advances

Diversity‐Oriented Two‐Step Annulative π‐Extension Enables Access to Structurally Complex Nanographenes

open access: yesAngewandte Chemie, EarlyView.
Pd‐catalyzed C–H arylation of polycyclic aromatic hydrocarbons (PAHs) with various aryltrimethylsilanes enables the preparation of structurally complicated arylated PAHs, which can be further transformed to nanographenes in a manner of two‐step annulative π‐extension (APEX) reaction.
