Luminosity Profiles of Merger Remnants

open access: yes, 1999
Using published luminosity and molecular gas profiles of the late-stage mergers NGC 3921, NGC 7252 and Arp 220, we examine the expected luminosity profiles of the evolved merger remnants, especially in light of the massive CO complexes that are observed ...

Spider Silk: Rapid, Bottom‐Up Self‐Assembly of MaSp1 into Hierarchically Structured Fibers Through Biomimetic Processing

open access: yesAdvanced Functional Materials, EarlyView.
Spider dragline silk has extraordinary mechanical properties due to the underlying hierarchical organization of the fiber across multiple length scales. A biomimetic platform for MaSp1 is developed, the main protein component of dragline silk, and thereby elucidates the parameters governing its rapid self‐assembly from soluble protein into complex ...

Efficient and Scalable Radiative Cooling for Photovoltaics Using Solution‐Processable and Solar‐Transparent Mesoporous Nanoparticles

open access: yesAdvanced Functional Materials, EarlyView.
Graded refractive index (GRI) structures are prepared from the layer‐by‐layer spray coating of the mesoporous SiO2 nanoparticles, showing high solar transparency and thermal emissivity. Under outdoor conditions, after 50 days, the GRI‐coated photovoltaics show on average 6.65 ± 1.48 °C lower than that of the non‐coated references, maintaining 80.9 ± 8 ...

2D Vermiculite Nanolaminated Membranes for Efficient Organic Solvent Nanofiltration

open access: yesAdvanced Functional Materials, EarlyView.
Intercalating multivalent cations into 2D vermiculite nanolaminates significantly improves the structural stability and sieving capabilities of membranes in both aqueous and organic media, rendering them effective for organic solvent nanofiltration. Abstract Membrane separation technology has found widespread application in molecular sieving and water ...

Virus‐Assembled Biofunctional Microarrays with Hierarchical 3D Nano‐Reticular Network

open access: yesAdvanced Functional Materials, EarlyView.
Virus‐assembled microdots with a wrinkled pattern induced by the high‐pressure carbon dioxide method show a morphology similar to sunflowers. Abstract Three‐dimensional (3D) hierarchical wrinkled materials built with biological entities have so far remained exclusive to nature.

Designing Metastable P3‐type Layered Negative Electrodes with High Na Vacancy Concentration for High‐Power Sodium‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
A metastable high‐vacancy concentration layered P3‐type Na0.5Cr0.5Ti0.5O2 negative electrode material has been synthesized from its K analogues P3‐type K0.5Cr0.5Ti0.5O2 using a facile room temperature ion‐exchange method. The P3‐type Na0.5Cr0.5Ti0.5O2 demonstrates a gravimetric capacity of 125 mA h g−1 and high‐rate performance (80% charging in 3 min ...

Perfect Ultraviolet Absorbers via Disordered Polarizonic Metasurfaces for Multiband Camouflage and Stealth Technologies

open access: yesAdvanced Functional Materials, EarlyView.
An ultrathin polarizonic metasurface achieves multiband camouflage and stealth with near‐perfect ultraviolet (UV) absorption, visible light blending, and infrared signature masking. Leveraging earth‐abundant materials, this design creates a reflective color palette through polarizonic effects, integrating transparent and non‐plasmonic materials.
