Giant Intrinsic Chirality Amplification of Aqueous Lead Halide Perovskite Nanocrystals via H‐Bond Driven Self‐Assembly Superstructures

open access: yesAdvanced Functional Materials, EarlyView.
Water‐assisted monoclinic CsPbBr3 transformation strategy is applied for synthesizing aqueous CsPbBr3/CsPb2Br5 nanocrystals with superior water‐repellent and excellent optical property. Low temperature enhanced hydrogen bonding network self‐assembled CsPbBr3/CsPb2Br5 nanocrystals into asymmetric superstructures, which exhibit notable circularly ...

Can Life develop in the expanded habitable zones around Red Giant Stars?

open access: yes, 2005
We present some new ideas about the possibility of life developing around sub-giant and red giant stars. Our study concerns the temporal evolution of the habitable zone.

Observation of Two‐Photon Resonant Raman Scattering via the Biexciton Level in Two‐Dimensional Halide Perovskite (C6H5C2H4NH3)2PbI4

open access: yesAdvanced Functional Materials, EarlyView.
Efficient two‐photon resonant Raman scattering (TRRS) is observed in the layered perovskite (PEA)2PbI4, with the biexciton level acting as an intermediate state. TRRS undergoes two‐photon frequency shift upon input frequency tuning, persists up to 90 K, and shows clear threshold behavior and polarization selection rules.

Giant Vortex Lattice Deformations in Rapidly Rotating Bose-Einstein Condensates

open access: yes, 2003
We have performed numerical simulations of giant vortex structures in rapidly rotating Bose-Einstein condensates within the Gross-Pitaevskii formalism. We reproduce the qualitative features, such as oscillation of the giant vortex core area, formation of

A Host‐Guest, Zeolite/Organocation Material With Isotropic Zero Thermal Expansion

open access: yesAdvanced Functional Materials, EarlyView.
The use of selected organic structure directing agents for the hydrothermal synthesis of targeted zeolites exhibiting negative thermal expansion provides a straightforward strategy to obtain a new class of host‐guest, nanostructured, crystalline zero thermal expansion materials made of light and abundant elements.

Residual‐Lithium‐to‐LiF Conversion Enables a LiF–Fluorinated Carbon Interphase for Reconstruction‐Resistant Ni‐Rich Cathodes

open access: yesAdvanced Functional Materials, EarlyView.
A fluorine‐rich acrylate monomer (PFHEA) was solvent‐free applied to NCM90 and thermally decomposed under Ar to convert residual lithium into LiF and form a pre‐built LiF/fluorinated amorphous carbon (LiF/FC) interphase. The LiF/FC layer suppresses NiO rock‐salt reconstruction and microcrack propagation, lowers interfacial resistance, and improves Li ...

Photothermal‐Activated Antibacterial Amyloid‐Polyphenol‐Iron Hydrogels for Synergistic Wound Healing

open access: yesAdvanced Healthcare Materials, EarlyView.
We report a thermally triggered supramolecular hydrogel (LTFe) formed by Fe3+ and tannic acid on lysozyme amyloid fibrils. Fe3+ enables rapid gelation and photothermal transduction with an efficiency of 88.56%. The LTFe hydrogel exhibits excellent biocompatibility, potent antibacterial activity against E. coli and S.
