Emergent Ferromagnetism at LaFeO3/SrTiO3 Interface Arising from a Strain‐Induced Spin‐State Transition

Advanced Materials Interfaces, EarlyView.
Strain at the LaFeO3/SrTiO3 interface induces spin‐state disproportionation, creating a checkerboard pattern of low‐ and high‐spin Fe3+ ions. This unusual configuration leads to interfacial ferromagnetism in an otherwise antiferromagnetic insulator. Using electron microscopy, spectroscopy, and density functional theory, this work reveals a new route to

Xerogel Films with Ordered Silica Nanorods Enable Fine‐Tuned Polarized Structural Colors in Modular Nanocomposite Films

Advanced Materials Technologies, EarlyView.
Xerogel films with aligned silica nanorods are prepared through a facile stretching and air‐drying approach. By controlling the alignment of silica nanorods and configuring multilayer film stacks, vibrant and tunable polarized structural colors with hues including green and orange are achieved.

Adaptive Elastin‐Like Hydrogel with Unidirectional and Controllable Anisotropic Actuation for Soft Robotics and Tissue Engineering

Advanced Materials Technologies, EarlyView.
Fiber‐reinforced elastin‐like tubular scaffolds are engineered to achieve anisotropic and reversible actuation under external stimuli. By adjusting fiber's angle, actuation behavior is finely tuned, enabling distinct actuation responses, even within different regions of the same scaffold.

Mode‐dependent Far‐field Radiation of Circularly Polarized Light by a Single Plasmonic Nanohelix

Advanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
The numerical simulations explored the chiroptical response and far‐field radiation behaviors of single plasmonic nanoantennas transitioning into helical structures. This study highlights the ability of these plasmonic nanohelices to regulate the far‐field directionality of radiation power and circular polarization in plasmon‐exciton coupled systems ...

A Dual‐Emissive DNA‐Templated Silver Nanocluster with Near‐Infrared I and II Emission

Advanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
This study presents a dual‐emissive DNA‐stabilized silver nanocluster with a nanosecond‐lived NIR‐I emission band and a microsecond‐lived NIR‐II emission band. Mass spectrometry establishes that the nanocluster has molecular formula (DNA)2[Ag17]11+. DNA sequence variations reveal critical nucleobases for stabilization, and modifications at the DNA 5 ...

The Influence of the Supporting Substrate on Single‐Particle Circular Differential Scattering of DNA Assembled Nanorod Dimers

Advanced Optical Materials, EarlyView.
For most microscopy measurements the sample is placed on a substrate, which causes symmetry breaking, especially relevant for chiral plasmonic nanostructures. DNA origami mediated X‐shaped AuNR dimers showing high structural purity in solution, exhibit significant diversity in lineshapes and signal intensities for their circular differential scattering

Large Electrogyration Effect in Ferroaxial NiTiO3 at Near Infrared Wavelengths

Advanced Optical Materials, EarlyView.
A large electrogyration effect (electric field‐induced optical rotation) is observed in a ferroaxial crystal NiTiO3 at near infrared wavelengths. The Ni2+ d‐d transitions, featuring strong magnetic dipole character, play an important role in producing the pronounced effect.

Precision Construction of Chiral Optical Fields with Nine Controllable Degrees of Freedom

Advanced Photonics Research, EarlyView.
Chiral optical fields (COFs) offer multiple controllable degrees of freedom (DOFs), enabling applications in optical tweezers, manufacturing, and encryption. However, achieving precise sidelobe control remains a challenge. This work introduces a modular multilayer annular phase plate to fine‐tune COFs by manipulating nine DOFs.
