An efficient approach to mechanically planar chiral rotaxanes

, 2014
We describe the first method for production of mechanically planar chiral rotaxanes in excellent enantiopurity without the use of chiral separation techniques and, for the first time, unambiguously assign the absolute stereochemistry of the products ...

Sulfur‐Free Ultrahigh‐Refractive‐Index Polymers Enabled by Densely Packed Oxygen‐Bridged Dibenzofuran‐Cardo Architectures

Advanced Functional Materials, EarlyView.
A new class of sulfur‐free, oxygen‐bridged dibenzofuran‐based polymers is developed for ultrahigh‐refractive‐index applications. The rigid π‐extended architecture and enhanced molecular polarizability enable exceptional optical performance, combining refractive indices up to 1.848 with high Abbe numbers and full visible transparency. This work offers a

Chiral polyoxometalate–cyclodextrin frameworks via Mn-mediated assembly: Enhanced stability and catalytic activity

Polyoxometalates
The application of polyoxometalate (POM) as building blocks to construct chiral POM-based functionalized frameworks remains a long-standing challenge. In this study, we report a chiral assembly by blending inorganic POMs and organic cyclodextrin (α-CD ...

Generation of out-of-plane polarized spin current by spin swapping

Nature Communications, 2023
The generation of spin currents and their application to the manipulation of magnetic states is fundamental to spintronics. Of particular interest are chiral antiferromagnets that exhibit properties typical of ferromagnetic materials even though they ...

Constraints on chiral operators in N=2 SCFTs [PDF]

, 2014
: We study certain higher-spin chiral operators in (formula presented)(formula presented) superconformal field theories (SCFTs). In Lagrangian theories, or in theories related to Lagrangian theories by generalized Argyres-Seiberg-Gaiotto duality (“type A”

High‐Throughput Discovery of Quantum Frustrated Materials

Advanced Functional Materials, EarlyView.
Physics‐guided discovery of frustrated kagome and triangular magnets. ABSTRACT Geometrical frustration provides a fertile platform for realizing exotic quantum phases such as spin liquids, yet, the predictive identification of frustrated magnets remains limited.

Dynamic Interfacial Charge Regulation for High-Fidelity Broadband Circularly Polarized Light Detection. [PDF]

Adv Sci (Weinh)
A photoelectrochemical circularly polarized light detector combines a multilayer chiral photonic film with a dynamically regulated BiVO4‐RGO‐MXene transducer. Broadband optical modulation from 360 to 830 nm is converted into stable electrical outputs through low‐noise solid‐liquid interfacial charge transfer, enabling self‐powered CPL discrimination ...

Disorder‐Broadened Topological Hall Phase and Anomalous Hall Scaling in FeGe

Advanced Functional Materials, EarlyView.
By systematically introducing defects into FeGe via ion‐beam modification, we demonstrate that disorder broadens the temperature regime over which the topological Hall effect ‐ a signature of skyrmions or other chiral textures — appears, while also increasing its magnitude.

Load Distributing Metamaterials Via Discrete Optimization

Advanced Functional Materials, EarlyView.
Mechanical metamaterials are computationally optimized to homogenize transmitted forces by minimizing the spread of reaction forces. The resulting architectures transform localized loading into broader, more uniform force distributions and experimentally demonstrate robust load spreading under quasi‐static and impact loading.
