Disentangling Polaron Formation Pathways in Y6 by Probing Noninteracting and Interacting Chromophores via Transient Absorption Spectroscopy

Advanced Materials, EarlyView.
The central role of both electronically interacting and noninteracting chromophores in the photogeneration of charges has been unambiguously identified by ultrafast pump‐probe spectroscopy in thin films of the prototypical non‐fullerene acceptor Y6. Onsager‐like autoionization from higher‐energy excitations on Y6 aggregates is found to control polaron ...

Vitamin C‐Induced Photo‐Redox Threshold Enables High‐Fidelity Volumetric Printing of Collagen

Advanced Materials, EarlyView.
Tomographic volumetric printing (TVP) of native proteins is limited by uncontrolled background crosslinking. Here, vitamin C is introduced as a biocompatible redox regulator to establish a tunable nonlinear polymerization threshold response for TVP.

Quantification of Magnetic Interactions in van der Waals Heterostructures Using Lorentz Transmission Electron Microscopy and Off‐Axis Electron Holography

Advanced Materials, EarlyView.
Cross‐sectional Lorentz TEM and off‐axis electron holography visualize the magnetic domain structure and quantify interlayer coupling in Fe3GeTe2/graphite/Fe3GeTe2 heterostructures. A stray‐field coupling length of 37±$\pm$7 nm marks the onset of domain misalignment between the layers.

Monolithically 3D‐Printed Spectral‐Spatial Meta‐Authenticators

Advanced Materials, EarlyView.
A single height map printed in a low‐index resin by two‐photon lithography encodes multiple visible wavelengths in one metasurface without any polarization optics. A fabrication‐aware optimization folds the printable height levels into the design, so the device is printed as optimized.

Wafer‐Scale Direct Growth of Ultraclean Monolayer Amorphous Carbon on c‐Sapphire by Remote Catalytic Dehydrogenation

Advanced Materials, EarlyView.
Remote catalytic dehydrogenation enables the direct growth of monolayer amorphous carbon on a 2‐inch sapphire wafer by thermal CVD. Spatial separation of the catalyst from the growth substrate eliminates metallic residue and post‐growth processing, yielding a wafer‐scale uniform film with a random polygonal sp2‐hybridized carbon network that exhibits ...

Photocatalytic Water Splitting on the Lunar Surface: Prospects for In Situ Resource Utilization

Advanced Materials Interfaces, EarlyView.
Water has been found in craters on the moon nearby locations which are illuminated >80% of the time. Photocatalysis uses energy from sunlight to drive chemical reactions such as water splitting to produce oxygen and hydrogen. It is a scalable technology that requires lighter equipment and utilizes resources available on the moon. ABSTRACT The discovery
