Rainbow Photonic Crystals: Self‐Assembly of Carbohydrate Bottlebrushes Block Copolymers

open access: yesAdvanced Materials, EarlyView.
Full‐color reflective 1D photonic crystals, capable of a tunable, responsive, and reversible color with high repeatability, are created from the self‐assembly of carbohydrate‐based brush block copolymers (BR01‐04). Abstract Tunable and responsive photonic crystal systems are the subject of great research interest owing to their ability to actively ...

Peptide‐Induced Ferroelectricity in Charge‐Transfer Supramolecular Materials

open access: yesAdvanced Materials, EarlyView.
Bio‐inspired supramolecular charge‐transfer amphiphiles self‐assemble into nanoribbons in water, where peptide chirality‐induced symmetry breaking generates robust ferroelectricity across multiple systems. These water‐processable organic ferroelectrics also enhance neuronal outgrowth and electrophysiological maturity, offering a versatile strategy for ...

In Situ Amine Formation to Modulate MOF‐Derived PdIn N‐Doped Carbon Catalysts

open access: yesAdvanced Materials, EarlyView.
An amine‐assisted approach converts PdIn‐MOF into PdIn intermetallic nanoparticles embedded in N‐doped carbon. In situ‐generated amines trigger early Pd nucleation, producing smaller PdIn domains than direct pyrolysis. Amine sterics and basicity tune composition and particle size, while solvent and amine co‐determine textural features.

Electron Channeling Contrast Imaging of Ferroelastic Domains

open access: yesAdvanced Materials, EarlyView.
A simple scanning electron microscopy technique, electron channeling contrast imaging, unveils nanoscale ferroelastic domains and their coupling to functional properties in oxide heterostructures. The work demonstrates high‐resolution mapping of both surface and buried domains, broadening the experimental toolbox for ferroic and quantum oxide systems ...

Field‐Free, Deterministic Giant Spin‐Orbit Torque Switching of 1.3 T Perpendicular Magnetization With Symmetry‐Lifted Topological Surface States

open access: yesAdvanced Materials, EarlyView.
We show a giant, bias‐field free, deterministic, spin‐orbit‐torque switching of perpendicular hard magnets with HC over 1.3 T. By combining the three‐fold 3m symmetry from topological insulator surface states with the rectangular mm2 symmetry from the 2 x 1 intercalation in Cr3Te4, the interface symmetry is significantly reduced into a unidirectional m

Femtosecond‐Laser‐Fabricated 3D CYTOP Microfluidic Chips Enabling Super‐Resolution Live Imaging of Cell Behavior in Confined Microspaces

open access: yesAdvanced Materials Technologies, EarlyView.
Using two‐photon polymerization of SU‐8 together with mold processing allowed the creation of defect‐free, flexible 3D microfluidic structures with sub‐micrometer precision in CYTOP. The fabricated CYTOP microfluidic chips enabled super‐resolution imaging of cancer cells in the microchannels, clearly visualizing previously undetectable fine structural ...
