Intrinsically‐Stretchable and Patternable Quantum Dot Color Conversion Layers for Stretchable Displays in Robotic Skin and Wearable Electronics

open access: yesAdvanced Materials, EarlyView.
Intrinsically‐stretchable, heavy‐metal‐free quantum dot color conversion layers are produced via a versatile crosslinking strategy. The color conversion layers exhibit minimal backlight leakage under mechanical strain, support high‐resolution patterning, and integrate seamlessly with micro‐light‐emitting diodes. Their incorporation in haptic‐responsive

Charge Transport and Carrier Polarity Tuning by Electrolyte Gating in Nickel Benzenehexathiol Coordination Nanosheets

open access: yesAdvanced Materials, EarlyView.
This work reveals that charge transport in nickel benzenehexathiol coordination nanosheets is governed by variable‐range hopping reflecting structural disorder. Electrolyte gating induces a switch in dominant carrier polarity from p‐type to n‐type and leads to an improvement in thermoelectric performance.

Full Wafer Scale Manufacturing of Directly Printed TiO2 Metalenses at Visible Wavelengths with Outstanding Focusing Efficiencies

open access: yesAdvanced Materials, EarlyView.
The highest experimentally determined focusing efficiency is reported here by using the direct imprinting of all‐inorganic TiO2 metalens arrays. Absolute efficiency greater than 80% and relative efficiency greater than 90% are achieved by optimization of all fabrication parameters controllable in the additive manufacturing process.
