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

ShadowMaskFormer: Mask Augmented Patch Embeddings for Shadow Removal [PDF]
Transformer recently emerged as the de facto model for computer vision tasks and has also been successfully applied to shadow removal. However, these existing methods heavily rely on intricate modifications to the attention mechanisms within the ...

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.

Ultralow iridium loading in hollandite MnO2 nanowires delivers an order of magnitude higher Ir mass activity than commercial IrOx for acidic water oxidation. Across pH and potential, Ir stays framework‐associated while Mn reconstructs, yet the most restructured catalyst is not the most dissolved, indicating that dissolution alone is an incomplete ...

Surface co‐functionalization of biodegradable nanofibers with sodium copper chlorophyllin and quaternary ammonium compounds achieves synergistic antimicrobial activity through combined photodynamic and contact‐killing mechanisms. The cationic surface provides humidity‐resistant electrostatic particle capture while maintaining rapid enzymatic ...

Shadow Economies around the World: What do we really know? [PDF]
Using the DYMIMIC approach, estimates of the shadow economy in 110 developing, transition and developed OECD countries are presented. The average size of the shadow economy (in percent of official GDP) over 1999-2000 in developing countries is 41%, in ...

Millifluidic Synthesis of Core–Shell Resonators For Tunable Sonic BandGaps in Acoustic Metamaterials
Millimeter‐scale core–shell acoustic resonators are fabricated by a gravity‐assisted dripping approach and incorporated into epoxy composites at controlled volume fractions. The resulting alumina–core resonator composites show tunable low‐frequency acoustic attenuation, demonstrating a scalable route for integrating locally resonant metamaterial units ...

Conformal Coating and Transfer of 2D Nanomaterials via Dynamic Interface Engineering
This review discusses conformal coating and transfer of two‐dimensional (2D) nanomaterials with a focus on dynamic interface engineering. By actively regulating nanosheet transport and interfacial contact during film formation, recent dynamic coating strategies overcome the limitations of conventional passive approaches and enable geometry‐adaptive ...

Xenon flash lamp annealing modulates oxygen‐vacancy states in 1‐nm‐thick ALD In2O3 transistors within a single 139 µs pulse. The photon‐induced defect engineering shifts the threshold voltage, improves bias‐stress stability, and narrows device‐to‐device variation across 64 devices. Combining pristine and treated transistors yields NMOS inverters with a
