Challenges of II‐VI and III‐V Blue Quantum Dot Light‐Emitting Diodes

Advanced Materials, EarlyView.
Blue‐emitting electroluminescent quantum dot light‐emitting diodes (QD‐LEDs) face critical challenges that limit their practical application, including short operational lifetimes, low color purity, broad spectral linewidths, and unpredictable transient effects like blinking and positive aging.

Beyond No No Tension: JWST z > 10 Galaxies Push Simulations to the Limit

The Open Journal of Astrophysics
JWST has identified some of the Universe's earliest galaxies, repeatedly pushing the frontier to ever higher redshifts and stellar masses. The presence of such extreme galaxies at such early times, with large stellar populations and high star-formation ...

Quadruple Helix Inversions of Liquid Crystals Orchestrated by Direct Chirality Transmission of an Intrinsically Chiral Light‐Driven Molecular Machine

Advanced Materials, EarlyView.
A molecular motor with four‐state dynamic chirality is integrated into liquid crystals, enabling quadruple sequential helix inversions and high helical twisting power. Due to high motor efficiency, the supramolecular helicity can be controlled by near‐infrared light via upconversion nanoparticles, resulting in a robust, multistate, photoresponsive soft

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

Advanced 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 ...

Fabrication of GaN Nanowire Arrays via Electrodeless Photoelectrochemical Etching and its Application on UV Photodetectors

Advanced Materials Interfaces, EarlyView.
A local electric field‐enhanced electrodeless photoelectrochemical (ELPEC) etching method facilitates the anisotropic evolution of GaN nanostructures from nanocones to hollow nanocones and eventually to nanowire arrays. This rapid, mask‐free approach offers a practical and scalable route for fabricating ultraviolet photodetectors with improved ...
